TL;DR: A timed Petri nets framework can be used to model and analyze a supply chain (SC) network which is subject to various risks and the overall system costs can be reduced by mitigation scenarios.

TL;DR: In this article, the authors deal with the development of a new logistics model and its application within the national freight model systems of Norway and Sweden, which operates at the level of individual firm-to-firm relations and simulates the choice of shipment size and transport chain for all the relations within the country, export and import.
Abstract: Practically every international, national or regional freight transport model system in the world lacks explicit treatment of logistics choices (such as shipment size considerations or the use of distribution centres). This paper deals with the development of a new logistics model and its application within the national freight model systems of Norway and Sweden. This logistics model operates at the level of individual firm-to-firm (sender-to-receiver) relations and simulates the choice of shipment size and transport chain for all (several millions) these relations within the country, export and import. A logistics model with deterministic cost minimisation has been constructed for both Norway and Sweden. The full random utility logistics model has not yet been estimated on disaggregate data, but this is planned for both countries. For Sweden, more limited disaggregate models for the choice of mode and shipment size have been estimated.

TL;DR: In this article, an integrated model for supplier selection has been proposed, where the supplier selection problem has been structured as an integrated lexicographic goal programming (LGP) and analytic hierarchy process (AHP) model including both quantitative and qualitative conflicting factors.
Abstract: Competitive international business environment has forced many firms to focus on supply chain management to cope with highly increasing competition. Hence, supplier selection process has gained importance recently, since most of the firms have been spending considerable amount of their revenues on purchasing. The supplier selection problem involves conflicting multiple criteria that are tangible and intangible. Hence, the purpose of this study is to propose an integrated model for supplier selection. In order to achieve this purpose, supplier selection problem has been structured as an integrated lexicographic goal programming (LGP) and analytic hierarchy process (AHP) model including both quantitative and qualitative conflicting factors. The application process has been accomplished in a food company established in Istanbul, Turkey. In this study, the model building, solution and application processes of the proposed integrated model for supplier selection have been presented.

TL;DR: This study proposes integrated fuzzy techniques for order preference by similarity to ideal solution (TOPSIS) and multi-choice goal programming (MCGP) approach to solve the supplier selection problem.
Abstract: Supplier selection is an important issue in supply chain management. In recent years, determining the best supplier in the supply chain has become a key strategic consideration. However, these decisions usually involve several objectives or criteria, and it is often necessary to compromise among possibly conflicting factors. Thus, the multiple criteria decision making (MCDM) becomes a useful approach to solve this kind of problem. Considering both tangible and intangible criteria, this study proposes integrated fuzzy techniques for order preference by similarity to ideal solution (TOPSIS) and multi-choice goal programming (MCGP) approach to solve the supplier selection problem. The advantage of this method is that it allows decision makers to set multiple aspiration levels for supplier selection problems. The integrated model is illustrated by an example in a watch firm.

TL;DR: In this paper, the authors developed a comprehensive framework that synthesizes approaches and contingency variables to manage the sustainability of multi-tier supply chains and sub-suppliers and identified several contingency variables (e.g., power, dependency, distance, industry, knowledge resources).
Abstract: Purpose – The purpose of this paper is to develop a comprehensive framework that synthesizes approaches and contingency variables to manage the sustainability of multi-tier supply chains and sub-suppliers. Design/methodology/approach – Using a systematic literature review, the authors analyse 39 studies and relevant theories to develop a comprehensive framework that integrates research efforts so far. Findings – The authors build a conceptual framework that incorporates four approaches to manage the sustainability of multi-tier supply chains. They also identify several contingency variables (e.g. power, dependency, distance, industry, knowledge resources) and their effect on the proposed approaches. Research limitations/implications – Based on the framework, six research propositions that advance the theories on multi-tier supply chain management, allow lead firms to develop comprehensive sustainable supply chain strategies and set the ground for future research in the area were developed.
