The cost effective management of a supply chain under stochastic influences, e.g. in demand or the replenishment lead time, is a critical issue. In this paper a multi-stage and multi-product supply chain is investigated where each member uses the (s,Q)-policy for inventory management. A bi-objective optimization problem to minimize overall supply chain costs while maximizing service level for retailers...
Complex and delocalized manufacturing industries require high levels of integration between production and transportation in order to effectively implement lean and agile operations. There are, however, limitations in research and applications simultaneously embodying further sustainability dimensions. This paper presents a methodological framework based on optimization and simulation to integrate...
A Mixed Integer Linear Programming model for the design and planning of green supply chains is developed. Strategic and tactical decisions are taken, namely on facility location and capacity installation, supplier selection, technology selection, transportation network definition, supply planning, and product recovery. The aim of this work is to study the use of environmental indicators in these decisions...
When planning the delivery in a supply chain, it is necessary to prepare a schedule of deliveries for different products at different sites during the planning horizon while satisfying demand and respecting material and financial resources constraints. In addition, to manage a supply chain, we need to solve problems such as the JRP (Joint Replenishment Problem) taking into account the problem of organizing...
The most important topic for researchers is supply chain, that takes into account environmental factors and social aspects. That is why top managers prefer taking into account key performance indicators currently. Harmonization of social, environmental and economic components makes development of supply chains sustainable. This document is based on environmental protection; it details the main features...
Collaborative supply chains have become an important element for recent years for many companies to improve their supply chain efficiency. This paper reviews the literature on operation research tools and methods for collaboration in supply chain. First, optimization methods for the collaborative supply chain are presented for both vertical and horizontal collaboration. In horizontal collaboration,...
This work describes a framework for the elaboration and evaluation of management policies for production and transportation supply chains in the forest product industry. The approach deals with the issue of coordination between the tactical and operational decision levels. First, we introduce LogiLab, a software system allowing to model the network and to optimize product flows in the supply chain...
To minimize the logistics cost in upstream and downstream enterprises in supply chain, Bi-level Programming Method is innovatively used in this article to establish the optimization model of the supply chain network distribution. Solving methods for this model are discussed and then an efficient arithmetic combined with layered iterative method is proposed. The model is calculated by Lindo software...
With the reformation of China's electric power and power coal system, several difficulties emerge in planning annual coal purchase and allocation schedule, e.g., with multiple sources, multiple destinations, different shipping vessels. So it is important to research on the transportation and storage problems for regional power coal allocation planning of China. In this study, these concerns are formulated...
The distribution problem in supply chain is studied in this article. To minimize the logistics cost in upstream and downstream enterprises in supply chain, Bi-level Programming Method is innovatively used in this article to establish the optimization model of the supply chain network distribution. Solving methods for this model are discussed and then an efficient arithmetic combined with layered iterative...
In order to analyze the impact of consumer's life-level on R/M integrated supply chain management, a method to describe the effect of the consumerpsilas life-level on the collecting price is shown, then an optimization model of R/M integrated supply chain by applying the description method is improved, and finally, the impact of consumerpsilas life-level on the management of R/M integrated supply...
This paper introduces a meta-heuristic enabled multi-agent optimization architecture for dynamic transportation planning in the supply chain procurement (SCP) plans. When multi-agent systems (MAS) are used for real-time dynamic optimization, agents seek the solution using distributed heuristics. However, distributed heuristics based on local information are prone to converge at local optimality. To...
