In this paper, we investigate the quality decision of a make-to-order (MTO) supply chain, where there may be different strategies between players. Before and after orders are placed in the market, the quality of the raw materials and the price of the products are set by the supplier and the manufacturer, respectively and production takes place. Due to the volatility of demand, the players are subject...
In this paper, we use a group decision-making (GDM) approach based on the variable precision rough set (VPRS) model to evaluate partner relationship in the value network of a mobile portal. We extend the existing study on VPRS-based GDM where the optimal betak-stable interval is derived for DMk [1]. Firstly, in the value network of a mobile portal, VPRS-based GDM is used to evaluate relationship between...
This paper examine the order allocation problems in a stochastic supply chain. The company in the supply chain can order raw materials from multiple suppliers. At any time of a supply order, the company should decide the optimal order quantities from suppliers to minimize the total purchasing cost and disruption risk, subject to maintaining a specified service level and quality. We develop an integrated...
Order allocation is one of the most critical activities of purchasing management in a supply chain. It is an unequally important multiple criteria decision making problem including cost, quality, delivery and service etc. In real situation, much input information is uncertain. In these cases the theory of fuzzy sets and stochastic theory are two of the best tools for handling this problem. Our fuzzy...
