Supply chain coordination has become a critical success factor for supply chain management (SCM). In the past few years, the researchers have widely emphasized that cooperation among supply chain (SC) firms is a key source of competitive advantage. This paper is focused on supply chain coordination from the perspective of inventory management. Li and Liu [1] developed a model for illustrating h...

This article examines how research productivity, administrative service, and teaching affect reputational capital in the market for academic economists. Also, we investigate the issue of the durability of reputational capital, estimating the penalties associated with gaps in research output. Our results reveal that (1) the market makes a distiniction between the quantity and the quality of an i...

One of the important issues in supply chain management is the coordination among different members of the supply chain. In this paper, we have studied a two-stage supply chain coordination problem under uncertain cost and demand information. The aim of the paper is to design a coordination mechanism through quantity discount policy under asymmetric information environment that allows the system...

Abstract—Concurrent planning of project scheduling and material ordering can provide more flexibility to the project scheduling problem, as the project execution costs can be enhanced. Hence, the issue has been taken into account in this paper. To do so, a mixed-integer mathematical model is developed which considers the aforementioned flexibility, in addition to the materials quantity discount...

In this research, two risk hedging strategies, the option contract and the advance purchase discount contract, are investigated within a manufacturer–retailer two-echelon supply chain context. This study offers three contributions. First, the optimal decisions under the two contracts from the perspectives of both the manufacturer and the retailer are determined. Second, circumstances under whic...

Nowadays, purchasing decisions are increasingly considering both tangible and intangible factors that in supplier selection. If suppliers have capacity or other different constraints, the problem is to identity the potential suppliers and to allocate the optimal order quantity among the selected suppliers. In this paper an integrated model of analytic hierarchy process (AHP) and preemptive goal...

We present a proportional reaction strategy in a repeated Cournot duopoly game with discounting. The strategy is based on increasing the total output quantity in proportion to deviations from a cartel point. Such a strategy was originally proposed by Osborne (1976) for a static oligopoly. We show that the resulting equilibrium is subgame perfect and weakly renegotiation proof when the possible ...

With the widespread use of manufacturing philosophies such as Just-In-Time (JIT), emphasis has shifted to the simultaneous consideration of cardinal and ordinal data in supplier selection process. Traditionally, many optimization models of supplier selection assume that the average prices of related expenditures are constant. This is far beyond the real situation. In fact, suppliers usually off...

We describe the cost-minimization problem faced by the purchasing department of a multi-plant company when its suppliers offer discounts based simultaneously on plant and on corporate purchases, when discount schedules depend on the total quantity (rather than cost) of ingredients purchased, and when alternative production recipes exist for each final product. We formulate the problem as a nonl...
