Achieving Sustainable Learning Through Erp Based Supply Chain in Vitro Laboratory
(Elsevier Science Bv, 2011) Gocer, Aysu; Saatcioglu, Omur Yasar; Demir, Muhittin H.; Tuna, Okan; Baltacioglu, Tuncdan; Adali, Erman
In order to enable sustainable learning, practical motivation behind every theory in consideration needs to be experienced extensively. The purpose of this study is to enhance sustainable learning on logistics and supply chain management through an in vitro laboratory environment in which real life supply chain structure is simulated over actual physical flows, and also through enterprise resource planning (ERP) systems, and then to measure the level of sustainability achieved. Research is conducted by including a group of students to a hands-on implementation through both physical and computerized applications in this representative business environment. To support the findings, surveys and focus groups are conducted. (C) 2011 Published by Elsevier Ltd.

Agility and Resource Dependency in Ramp-Up Process of Humanitarian Organizations
(Emerald Group Publishing Ltd, 2019) Qing, Lu; Wu, Jie; Goh, Mark; De Souza, Robert; Lu, Qing
Purpose The ramp-up in humanitarian logistics operations is a stage when the demand surges, often at the start of an emergency. In response, agility is a key strategy used by the humanitarian organizations (HOs). However, the HOs are constrained by their existing resources and have to respond in the ramp-up process under their resource dependency. The purpose of this paper is to develop a framework on agility-building strategies used by HOs for the ramp-up. Design/methodology/approach This study applies both the dynamic capabilities perspective and resource dependence theory to humanitarian relief operations, and develops four testable propositions to explore the agility-building strategies of the HOs for the ramp-up process. A multiple-case study is conducted on six international HOs operating in Indonesia to verify them, in addition to an extensive literature search. Findings The case study shows that the human resource management, pre-positioning, standardization and supplier management of the HOs are all related to their resources and environment in the ramp-up process. The authors highlight the practical differences between the few super large, resource rich and centralized HOs with the second-tier HOs. Research limitations/implications - Given the small sample size and single country as the site of study, some findings may not be applicable to the other HOs or in other regions. Practical implications - The propositions could be applicable to other HOs operating under similar environments, and potentially to the commercial enterprises operating in a highly volatile environment with severe resource scarcity. Originality/value This study provides new insights into ramp-up operations and into how HOs build their agility and reduce their resource dependencies. Theoretically, the paper applies two established theories in the strategic management literature to a new field.

Approaches To Managing Global Sourcing Risk
(Emerald Group Publishing Ltd, 2011) Christopher, Martin; Mena, Carlos; Khan, Omera; Yurt, Oznur
Purpose - Global sourcing can bring many benefits to organisations, but it can also expose them to a number of risks. The purpose of this study is to understand how managers assess global sourcing risks across the entire supply chain and what actions they take to mitigate those risks. Design/methodology/approach - A multiple case study approach was used, involving 15 cases in seven different industries. Each case consisted of interviews with manager; directly involved in the global sourcing decision, supported by documentary evidence. A cross-case analysis was conducted to analyse patterns across different industries. Findings - The study revealed that most companies do not have a structured supply chain risk management and mitigation system. Nevertheless they do use a number of informal approaches to cope with risk. The paper proposes that a multidisciplinary approach is required when dealing with global sourcing risks. It presents a classification of risks covering four categories: supply risk, process and control risks, environmental and sustainability risks, and demand risks. Originality/value - The paper addresses a research gap concerning managers' approaches to assessing and mitigating supply chain risk in a global context. In this context, this study proposes a new categorisation for global sourcing risks and offers a characterisation of global sourcing risk mitigation strategies applicable to different industries.

Assessing Consumer Logistics Functions in Grocery Shopping: Evidence From an Emerging Market
(Routledge Journals, Taylor & Francis Ltd, 2020) Hüseyinoğlu, Işık Özge Yumurtacı; Kotzab, Herbert; Kostepen, Kubra Goksu; Halaszovich, Tilo; Yumurtacı Hüseyinoğlu, Işık Özge
Consumer logistics (CL), focuses on the role of consumers in the logistical processing of goods for the purpose of consumption from point of acquisition to the point of disposal. The objective of this study is to test and validate the CL scale as introduced by Bahn, Granzin, and Tokman for grocery shopping in a previously unexplored country setting, namely in Turkey. Our findings show in contrast to Bahn et al. only six CL functions: information search, transportation management and materials handling, storage management & inventory needs assessment, contingent inventory operations & product acquisition, intra-household communication, and interdependent transportation operations. These six CL functions are more applicable for an emerging market, such as Turkey. These findings are consistent across the different socio-demographic characteristics in our sample.

An Attribution Approach To Consumer Evaluations in Logistics Customer Service Failure Situations
(Wiley, 2012) Oflaç, Bengü; Sullivan, Ursula Y.; Baltacioglu, Tuncdan
The primary goal of this study is to investigate the roles of expectations and purchase criticality on consumers' brand perceptions and attribution behaviors in service delivery failures. The provision of logistics services is often a crucial point in supply chain management that can influence brand perceptions of customers. Indeed, the level and the quality of customer service provided may determine whether the organization will retain existing customers or even attract new ones. As a consequence, a failure in logistics customer service and its effect on overall perceptions of a brand should not be underestimated. Furthermore, the involvement of a third-party logistics (3PL) company in this failure situation can create considerable shifts in the responses of consumers, especially in the attribution behavior for cause of failure. By applying scenario-based experiments, this study demonstrates the dynamics by which customer expectations, purchase criticality and 3PL companies affect consumer brand perceptions and attributions. The results suggest the presence of two expectation-based buffering effects in delivery failures. The first buffering effect is revealed in overall brand evaluation and repurchase intention, while the second buffering effect is observed in consumer brand attribution. The findings indicate that higher expectations may protect the brand and cause more attribution to the third-party service provider. Additionally, it is shown that criticality of the purchase has crucial impacts on brand evaluations and attributions.
Beyond the Literature: a Comparative Analysis of Sustainability Benefits and Risks of Crowd Delivery Businesses in Research and Practice
(Elsevier, 2025) Gocer, Aysu; Izcan, Elif; Vural, Ceren Altuntas
Crowd delivery (CD) business provides an innovative service in managing the tension between delivery speed and cost, while providing work for individuals. While CD is recognized as a promising business in literature, consistently acknowledging its positive impacts on sustainability, real-world practices underscore the prominence of sustainability-related challenges related to managing CD volume, liability, security, trust, and environmental issues. This study aims to bridge this gap between research and practice in CD business sustainability by examining current practices against existing knowledge, investigating sustainability benefits and risks, and identifying discrepancies to understand the business's changing dynamics. In that respect, a multi-method approach is employed, combining systematic literature review (SLR) and semi-structured interviews. Comparative content analysis between research and field data identifies sustainability benefits and risks for CD businesses for environmental, social and economic dimensions and outlines different perspectives of academic studies and field data. This research sheds light on the evolving relationship between theoretical understanding and realworld implementation of the sustainability benefits and risks of CD business under four categories: (1) "research supported by practice", (2) "research/practice transformed", (3) "in practice only", and (4) "in literature only". These categories underscore the dynamic nature of sustainability in the context of CD businesses, demonstrating areas of convergence and divergence between research and practice and highlighting the need for ongoing development of theoretical frameworks to reflect real-world practices. The implications of this study have the potential to both guide academic research towards practical concerns and enable practitioners to improve CD business sustainability for all stakeholders.

A Bi-Objective Multimodal Transportation Planning Problem With an Application To a Petrochemical Ethylene Manufacturer
(Palgrave Macmillan Ltd, 2018) Tokcaer, Sinem; Özpeynirci, Özgür
The aim of this paper is to analyze and improve the freight transportation plan by considering multimodal transportation with maritime, road, and railway transportation. We develop a bi-objective mathematical model, of which objectives are total cost and number of handling operations, an indicator for operational difficulty. The model decides on the optimal multimodal transportation plan including ship chartering and transportation mode decisions. We generate the Pareto frontier to allow an insight into the trade-offs in changing the transportation mix. We test the mathematical model on real-life instance of a petrochemical ethylene manufacturer located in Turkey, originally used in Ozpeynirci et al (Marit Econ Logist 16: 188-206, 2014). In addition to Ozpeynirci et al (Marit Econ Logist 16: 188-206, 2014), this paper considers a secondary objective and includes rail transport as a third mode in the multimodal transportation mix. In order to analyze the changes in ship chartering and mode selection decisions, we introduce three different scenarios and show that small changes in the transportation mode without restructuring the distribution network may result in significant savings.

A Branch and Price Algorithm for the Pharmacy Duty Scheduling Problem
(Pergamon-Elsevier Science Ltd, 2016) Ceyhan, Gokhan; Özpeynirci, Özgür
Pharmacy Duty Scheduling (PDS) is the activity of assigning pharmacies to days during a planning horizon with the purpose of serving society outside regular working hours. In Turkey, pharmacies are retailers who operate during the working hours in weekdays. However, demand for medicine at nights, at the weekends and on holidays must be satisfied by allocating times to pharmacies to open at these times. The problem is a multi-period p-median problem with the additional problem specific constraints, and it is NP-Hard. In this study, we develop a branch-and-price algorithm to solve the PDS to optimality. We decompose the problem into single period problems and apply column generation on the decomposed problem. We propose several enhancements on the algorithm and conduct computational tests on randomly generated instances to compare the performance of the developed algorithm with the state-of art general purpose solver. The branch-and-price algorithm outperforms the state-of-art general purpose solver. (C) 2016 Elsevier Ltd. All rights reserved.

The Causes of Food Waste in the Supplier-Retailer Interface: Evidences From the Uk and Spain
(Elsevier, 2011) Mena, Carlos; Adenso-Diaz, B.; Yurt, Oznur
Food and drink waste is a significant problem for economic, environmental and food security reasons. Government efforts have focused on diverting waste away from landfill through regulation, taxation and public awareness. However, efforts to understand why waste occurs have been limited, particularly in the interface between retailers and suppliers. This research aims to address this problem by identifying the main root causes of waste in the supplier-retailer interface. The research is exploratory in nature as there is a paucity of studies focusing on food waste across the supply chain. Data were collected through 43 interviews with managers in food manufacturing, wholesaling and retailing in two countries: the UK (24) and Spain (19). Data from the interviews and supplementary documentation were analyzed using causal maps. This approach helped to identify the main root causes of waste which were categorized into three groups: (1) mega-trends in the marketplace, (2) natural causes related to the products and processes, and (3) management root causes on which practitioners have a direct impact. The paper discusses the root causes of food waste and good practices identified from the interviews. Differences between the UK and Spain are discussed, presenting potential learning opportunities for practitioners in these countries and highlighting opportunities for further research.

Comparison of Simulated Annealing, Interval Partitioning and Hybrid Algorithms in Constrained Global Optimization
(Springer-Verlag Berlin, 2008) Pedamallu, Chandra Sekhar; Özdamar, Linet
The continuous Constrained Optimization Problem (COP) often occurs in industrial applications. In this study, we compare three novel algorithms developed for solving the COP. The first approach consists of an Interval Partitioning Algorithm (IPA) that is exhaustive in covering the whole feasible space. IPA has the capability of discarding sub-spaces that are sub-optimal and/or infeasible, similar to available Branch and Bound techniques. The difference of IPA lies in its use of Interval Arithmetic rather than conventional bounding techniques described in the literature. The second approach tested here is the novel dual-sequence Simulated Annealing (SA) algorithm that eliminates the use of penalties for constraint handling. Here, we also introduce a hybrid algorithm that integrates SA in IPA (IPA-SA) and compare its performance with stand-alone SA and IPA algorithms. All three methods have a local COP solver, Feasible Sequential Quadratic Programming (FSQP) incorporated so as to identify feasible stationary points. The performances of these three methods are tested on a suite of COP benchmarks and the results are discussed.

Compartmental Disease Transmission Models for Smallpox
(Amer Inst Mathematical Sciences-Aims, 2011) Adivar, Burcu; Selen, Ebru Selin
Mathematical models are importants tool to develop emergency response plans and mitigating strategies for an anticipated epidemic or pandemic attack. With the objective of minimizing total number of deaths, total number of infected people, and total health care costs, mitigation decisions may include early response, vaccination, hospitalization, quarantine or isolation. In this study, smallpox disease transmission is analyzed with a compartmental model consisting of the following disease stages: susceptible, exposed, infectious, quarantined and recovered. Considering natural birth and death rates in a population, two models are developed to study the control and intervention of smallpox under the assumption of imperfect quarantine. First model is an ordinary differential equation (ODE) model assuming exponential distribution function and the latter is a general integral equation model with gamma distribution. Numerical results are provided and model results are compared to demonstrate the differences in the reproduction numbers, which can be described as the threshold for stability of a disease-free equilibrium related to the peak and final size of an epidemic.

Consumer Response To Recovery Efforts for Online Product Failures: an Empirical Study for Turkey
(Routledge Journals, Taylor & Francis Ltd, 2016) Oflac, Bengu Sevil
This study explores recovery satisfaction and repatronage-related differences for different levels and types of distributive, procedural, and interactional justice and tests the mediating role of recovery satisfaction in justice-repatronage relationships for online product failures. Results show that high levels of procedural and interactional justice increase recovery satisfaction and repatronage for the aforementioned type of failures. Findings also indicate that for online product failures, regarding distributive justice, refund creates more recovery satisfaction than exchange. Additionally, recovery satisfaction acts as a mediator between procedural justice and repatronage variables. This mediating role is also valid for the interactional justice-repatronage relationship.

Designing an Optimal Contract Mechanism in a Cellulosic Biofuel Enterprise
(Springer Heidelberg, 2022) Tokcaer, Sinem; Onal, Hayri; Özpeynirci, Özgür
Energy security and environmental concerns resulting from fossil fuel consumption have led to important changes in the U.S. energy policy in the past two decades. One of those is the Renewable Fuel Standard that mandates blending biofuels, especially cellulosic biofuels, with conventional transportation fuels. This requires producing substantial amounts of biomass for which currently there is no established market. Potential producers would grow energy crops only if appropriate guarantees and economic incentives are provided. Similarly, cellulosic biorefineries need a guaranteed and steady flow of biomass at a low price. Biorefinery managers and biomass producers are independent decision-makers operating in a hierarchical order and have conflicting economic interests. We hypothesize a contracting mechanism between biomass producers and biorefineries to address this complexity and formulate the problem as a two-level optimization model. While being a realistic representation, the model is computationally challenging. To address this issue, we introduce a search algorithm based on the optimization theory to solve the optimal biomass price and biorefinery size. We apply this approach to a hypothetical cellulosic biorefinery located in the U.S. Midwest. We present numerical results of the model along with sensitivity analysis on some key parameters. The results show that: (1) current cellulosic biofuel subsidy provided by the US government is highly inadequate to support an economically viable enterprise, (2) distances between biomass producers and the biorefinery and risk-taking behavior of farmers are crucial factors, and (3) under the estimated yield and production costs, Miscanthus would be the main source of biomass.
Determinants of Customers' Intention To Adopt Last Mile-Attended Service Points
(Istanbul Univ, Sch Business, 2025) Oflac, Bengu Sevil; Ozcan, Seda
This study investigates the determinants influencing consumer intention relating to attended service points in last-mile delivery, which has received less attention than the unattended model. In this regard, we examine the effects of perceived value, online shopping delivery risk, and environmental concerns on attended service point (ASP) adoption. Survey data were collected from 299 consumers. We used the structural equation modeling approach by using AMOS software for data analysis. The results indicate that hedonic values associated with ASPs, last-mile incentives, and online shopping delivery risk are critical and positively affect customer attitudes, which turn into intentions toward ASPs. From a managerial perspective, this research offers several insights into e-commerce and logistics service provider companies' ASP penetration strategies in emerging markets. This study contributes to the academic body of knowledge by enriching the literature on the ASP model in last-mile delivery and investigating the determinants that impact consumers' attitudes and intentions to use ASPs in an emerging market context.

The Doer Effect of Failure and Recovery in Multi-Agent Cases: Service Supply Chain Perspective
(Emerald Group Publishing Ltd, 2018) Yildirim, Cansu; Oflac, Bengu Sevil; Yurt, Oznur
Purpose The purpose of this paper is to explore the doer effect of service failure (SF), good prior experience (GPE) and recovery on overall customer satisfaction and repurchase intentions for multi-agents in tourism service supply chain (TSSC). It specifically focuses on internal and external failure and recovery. Design/methodology/approach The study employs a 2x2x3 between-subjects experimental design with 12 diverse scenarios. It aims to examine the main effects of GPE and the interaction effects of SF and recovery on overall customer satisfaction and repurchase intentions. Findings The main findings show that consumers do not show favorable behavioral outcomes when they have GPE with an affiliated party. Results of the experiments demonstrate that for hotels, there is no interaction effect between failure and recovery regarding overall customer satisfaction and repurchase intentions; however, for travel agencies, an interaction effect has been found. This indicates that an internal failure (by travel agency) should be recovered internally to increase the behavioral outcomes for travel agency. However, if there is an external failure (by hotel) then the essential thing is providing a recovery. Originality/value Although the service literature covers failure and recovery in diverse contexts, these concepts are rarely studied from a multi-agent perspective in the service supply chain literature. In such a chain, a failure by a different party may remain unresolved, and this may create a positive effect on another party, if they provide recovery for the failure. This means that the doer of the failure and/or recovery (the party responsible from the failure and/or recovery) may have an impact on behavioral outcomes. However, previous literature has neglected to focus on the important issue of which entity/party performs the failure and/or recovery, and the effect on behavioral outcomes. By focusing on a principal-agent relationship in a TSSC, the study aims to address this research gap.

Drivers of and Barriers Against Market Orientation: a Study of Turkish Container Ports
(Palgrave Macmillan Ltd, 2019) Gocer, Aysu; Vural, Ceren Altuntas; Deveci, Durmus Ali
Privatization transforms the operations-focused and stakeholder-independent approach of container port management into a competition and market-oriented perspective. This integrates a marketing philosophy with the management of the overall port organization. In this way, ports become more responsive to market demand and create profitable and sustainable customer value, so as to achieve competitive advantage. This change is caused both by the evolving port governance systems, as well as by changing market demand, requiring ports to respond to the needs of the supply chains they serve. An increasingly prevalent logistics perspective in maritime transport is accelerating pressure on ports and other members of service supply chains encouraging them to adopt market-oriented strategies. Accordingly, the purpose of this study is to discover both the drivers and the barriers that container ports face while adopting market-oriented strategies. Taking Turkish container ports as the main unit of analysis, this article combines the Delphi method with fuzzy analytic hierarchy processing to identify the prioritized opinions of industry stakeholders. The results indicate that customer relations are perceived to be very important for container ports, in terms of communicating value-added services, and even more important than economic concerns or possessing market knowledge. Often, however, ports define their customers within a limited scope, and fail to adopt a supply chain perspective. Therefore, new strategies, such as market resegmentation including support service providers, or evaluating end-customer demands by analyzing supply chains that include port services, should be developed to eliminate the prioritized barriers. Drivers, such as collecting market information, or building market-oriented teams, can be used more effectively to make market orientation a new competition tool for all ports. Finally, our results provide new variables to scholars studying port marketing and put forward recommendations for testing the relationships between these variables.

Drivers of Geographical Indication Food Supply Chain Performance: a B2b Network Perspective
(Emerald Group Publishing Ltd, 2024) Polater, Abdussamet; Yumurtacı Hüseyinoğlu, Işık Özge; Kingshott, Russel P. J.; Schepis, Daniel; Huseyinoglu, Isik Ozge Yumurtaci
PurposeThis study aims to examine the role relational dynamics, grounded in the theories of social exchange and social capital, play within the context of geographic indication (GI) food supply chain network (FSCN) performance.Design/methodology/approachA total of 30 qualitative interviews were undertaken with key informant stakeholders across a variety of organizations within Turkish GI FSCNs. An open, axial and selective grounded theory coding process was used for the analysis, teasing out critical themes that underpinned the conceptual framework.FindingsThe findings identify the formal and informal mechanisms which govern GI FSCNs. These two forms of governance mechanisms influence network performance, which was found to comprise logistics, production, business and socio-economic performance dimensions. Transparency, GI traceability, trust and psychological contract violations were found to mediate the link between governance and network performance outcomes.Originality/valueTo the best of the authors' knowledge, this study is the first to explore GI FSCNs from the perspective of relationship marketing and through the lens of social exchange and social capital theory. Accordingly, both academics and practitioners can benefit from the study, as it unveils relevant relational factors underpinning such networks.

A Dynamic Logistics Coordination Model for Evacuation and Support in Disaster Response Activities
(Elsevier Science Bv, 2007) Yi, Wei; Ozdamar, Linet
This paper describes an integrated location-distribution model for coordinating logistics support and evacuation operations in disaster response activities. Logistics planning in emergencies involves dispatching commodities (e.g., medical materials and personnel, specialised rescue equipment and rescue teams, food, etc.) to distribution centres in affected areas and evacuation and transfer of wounded people to emergency units. During the initial response time it is also necessary to set up temporary emergency centers and shelters in affected areas to speed up medical care for less heavily wounded survivors. In risk mitigation studies for natural disasters, possible sites where these units can be situated are specified according to risk based urban structural analysis. Logistics coordination in disasters involves the selection of sites that result in maximum coverage of medical need in affected areas. Another important issue that arises in such emergencies is that medical personnel who are on duty in nearby hospitals have to be re-shuffled to serve both temporary and permanent emergency units. Thus, an optimal medical personnel allocation must be determined among these units. The proposed model also considers this issue. The proposed model is a mixed integer multi-commodity network flow model that treats vehicles as integer commodity flows rather than binary variables. This results in a more compact formulation whose output is processed to extract a detailed vehicle route and load instruction sheet. Post processing is achieved by a simple routing algorithm that is pseudo-polynomial in the number of vehicles utilized, followed by the solution of a linear system of equations defined in a very restricted domain. The behavior and solvability of the model is illustrated on an earthquake scenario based on Istanbul's risk grid as well as larger size hypothetical disaster scenarios. (c) 2006 Elsevier B.V.

Efficient Interval Partitioning - Local Search Collaboration for Constraint Satisfaction
(Pergamon-Elsevier Science Ltd, 2008) Pedamallu, Chandra Sekhar; Ozdamar, Linet; Ceberio, Martine
In this article, a cooperative solution methodology that integrates interval partitioning (IP) algorithms with a local search, feasible sequential quadratic programming (FSQP), is presented as a technique to enhance the solving of continuous constraint satisfaction problems (continuous CSP). FSQP is invoked using a special search tree management system developed to increase search efficiency in finding feasible solutions. In this framework, we introduce a new symbolic method for selecting the subdivision directions that targets immediate reduction of the uncertainty related to constraint infeasibility in child boxes. This subdivision method is compared against two previously established partitioning rules (also parallelized in a similar manner) used in the interval literature and shown to improve the efficiency of IP. Further, the proposed tree management system is compared with tree management approaches that are classically used in IP. The whole method is compared with published results of established symbolic-numeric methods for solving CSP on a number of state-of-the-art benchmarks. (c) 2006 Elsevier Ltd. All rights reserved.

An Empirical Investigation of Swift Trust in Humanitarian Logistics Operations [2018]
(Emerald Group Publishing Ltd, 2018) Qing, Lu; Goh, Mark
Purpose Trust is essential for any team working together. In humanitarian logistics operations, relief organizations often have to work collaboratively in hastily formed networks. Trust in such a context, termed as swift trust in the literature, is an important but less explored topic. The purpose of this paper is to empirically explore the antecedents of swift trust as well as its impact on the coordination among the humanitarian workers. Design/methodology/approach The authors choose the humanitarian workers in Southeast Asia as the research sample. An exploratory survey study is conducted in three Southeast Asian countries, namely, Singapore, Indonesia, and the Philippines, with 89 usable responses. Findings The empirical results have shown support for most hypotheses. Third-party certification, competency, similarity in procedure standards and organizational values, can all generate swift trust. Moreover, swift trust can lead to greater openness in information sharing for coordination, though not to active assistance. Both coordination activities would lead to greater coordination effectiveness. Research limitations/implications Future studies could examine the four antecedent conditions for swift trust with better proxies. The connection between swift trust and coordination effectiveness can be explored in depth. Practical implications NGOs and governments could use these means effectively to build swift trust among the humanitarian players. For example, organizing field-oriented training activities would be beneficial for humanitarian workers in both network building and enhancing personal competency. Originality/value The findings point to the importance of swift trust in humanitarian operations and identify several means to enhance this trust. It has filled a research gap on the empirical investigation of the antecedents and impact of swift trust on inter-organizational coordination in humanitarian logistics operations.
