Sourcing from emerging economies may yield direct cost savings, but companies often face greater risk of supplier responsibility problems due to many factors, with lax regulatory enforcement in these regions being one of them. Intuitively, to mitigate such risks, companies can design incentive schemes in sourcing contracts and invest in screening mechanisms for supplier sourcing. However, the r...

Determining the optimum number of suppliers and the optimum quantities to order from each of them is a critical problem for any supply chain. This paper has mathematically arrived at conditions to identify the appropriate sourcing strategy in a multi-period scenario for a stochastic supply and a stochastic demand environment. It has also obtained the total order quantity, optimum number of supp...

    Supplier selection,   Multi-objective decision making,   Fuzzy Compromise programming,   Supply chain management,   Quantity discount .   Supplier selection is naturally a complex multi-objective problem including both quantitative and qualitative factors. This paper deals with this issue from a new view point. A quantity discount situation, which plays a role of motivator for buyer, is con...

In today’s severe competitive environment the selection of appropriate suppliers is a significantly important decision for effective supply chain management. Appropriate suppliers reduce purchasing costs, decrease production lead time, increase customer satisfaction and strengthen corporate competitiveness. In this study a multiple sourcing supplier selection problem is considered as a multi ob...

This paper reviews inventory models with multiple supply options and discusses their contribution to supply chain management. After discussing strategic aspects of supplier competition and the role of operational flexibility in global sourcing, inventory models which use several suppliers in order to avoid or reduce the effects of shortage situations are outlined. Further, related inventory pro...

Supplier selection and order allocation decisions are the main parties of a supply chain network which has high impact on economic performance this network. This study using an Economic Order Quantity (EOQ) concept proposes optimization model for integrated supplier problem where lot sizing, discounts, disruptions contributed among first studies in research area. To address uncertainty, scenari...
