A modified multi-criterion optimization genetic algorithm for order distribution in collaborative supply chain

Supply chain collaboration is prevalent in today’s business model, and has been recognized to be one of the important issues in improving competition strength. Order distribution is to determine which order should be allocated to which supplier, it plays a very important role in a collaborative supply chain, because different order distribution infers different benefit under different criteria. However, there is not much research on the order distribution methodology. This paper adopted a framework of a central coordination system, which is equipped with a multi-criteria genetic optimization feature. In the previous multi-criterion optimization genetic algorithm (MCOGA), the analytic hierarchy process (AHP) is deployed to evaluate the fitness values. In this paper, a modified MCOGA is proposed based on the technique for order preference by similarity to ideal solution (TOPSIS). There are two main parts, namely, searching and evaluation, in genetic algorithms. Compared with the MCOGA, the proposed method takes the advantage of less complexity in the evaluation stage. The numerical example of order distribution is used to illustrate the efficiency of the proposed method.     

An integrated multiple criteria decision making model applying axiomatic fuzzy set theory

This article presents a hybrid model for the multiple criteria decision making problems. The proposed decision model consists of three parts: (i) DEA (data envelopment analysis) is used to provide the best combination on the performance parameters of original data; (ii) By the application of AFS (axiomatic fuzzy set) theory and AHP (analytic hierarchy process) method, the weight of each attribute is calculated and (iii) TOPSIS (technique for order preference by similarity to ideal solution) is applied to provide the ranking order of that best combination based on the weights of attributes. In addition, we also provide the definitely semantic interpretations for the decision results by AFS theory. Specially, the model not only employs the performance parameters from raw data, but also considers the preferences from decision-makers that can make the decision results more reasonable. The proposed model is used for robot selection to verify the proposed model. Using the selection index, the evaluation of alternative robots and the selection of the most appropriate are eventually feasible. Moreover, a numerical example for supplier selection is included to illustrate the application of the model for the newly developed problems.     

基于模糊模式识别的动态联盟伙伴选择模型

在基于模糊模式识别的伙伴选择方法中,将TOPS IS方法借助于一个多属性决策问题的“理想解”和“负理想解”去排序的思想应用到其伙伴选择过程中,根据贴近度的公理化定义对TOPS IS方法作以修改,构造出“相对”贴近度,以此折衷地衡量动态联盟合作伙伴的优劣。避免了传统模糊模式识别单纯利用“绝对”贴近度所造成的结果均一化、可比性差的现象,从一定程度上减少了因贴近度选用的不同而造成的结果差异。从某种意义上来说,该种方法可以作为TOPS IS方法的拓展,是本文具有新意之处。
