Abstract

Nowadays, experts believe there are abundant sources of risks in a supply chain. An important group of risks against a supply chain is the disruption risks group, which disturbs the flow of material in the chain and may lead to inefficiency in providing the final product in the supply chain. The aim of this article is to investigate the control of costs of disruption in a supply chain by considering the possibility of disruption. In fact, this research focuses on determining the best combination of suppliers and quota allocation with regards to disruption in suppliers. The proposed multi-objective mathematical model in this paper is a mixed-integer programming (MIP) model with objective functions to minimize transaction costs of suppliers, expected costs of purchasing goods, expected percentages of delayed products, expected returned products, and to maximize expected evaluation scores of the selected suppliers. Due to the uncertainty of demand and supplier disruption in the real world, their values are also considered uncertain; the proposed multi-objective model is studied by using a scenario-based stochastic programming (SP) method. In this method, all possible predictions for demand and disruption values are simultaneously included in the model; objective function results have more optimal value than a separate solution of the model for each predicted value.

基于场景的方法求解多目标供应商选择和配额分配问题

如今，专家们认为供应链中存在着大量的风险来源。供应链上的一组重要风险是中断风险组，它扰乱了供应链中的物料流动，并可能导致供应链中提供最终产品的效率低下。本文的目的是通过考虑中断的可能性来研究供应链中断的成本控制。事实上，本研究的重点是在供应商中断的情况下确定供应商和配额分配的最佳组合。本文提出的多目标数学模型是一个混合整数规划(MIP)模型，其目标函数是最小化供应商的交易成本、期望采购成本、期望延迟产品百分比、期望退货产品百分比，以及最大化所选供应商的期望评价分数。由于现实世界中需求和供应商中断的不确定性，它们的价值也被认为是不确定的;采用基于场景的随机规划方法对多目标模型进行了研究。在该方法中，所有可能的需求和中断值预测同时包含在模型中;目标函数的结果比每个预测值单独求解的模型具有更优的值。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
