The wide range of products and services that are being sourced today has made the company’s procurement organization an increasingly important function. The complexities of managing sourcing options is greater than ever making the procurement function critical for overcoming an increasingly global, complex and uncertain sourcing environment. This paper discusses an overview of relevant sourcing...

In this paper, a mathematical programming model is presented for integrated problem of closed loop supply chain network design and supplier selection. The suppliers  propose discount policy based on purchase amount and loyalty of buyers which are both taken from the elements of RFM (Recency, Frequency and Monetary) technique. The main objective of this paper which is formulated by a mixed-integ...

Little attention is given in the literature to decisions on the appropriate selection of suppliers, and on assigning order quantities to these suppliers, in the case of multiple sourcing, with multiple criteria and with suppliers' capacity constraints. Only a few mathematical programming models to analyse such decisions have been published to date, and these have tended to consider only net pri...

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

A supplier has a periodic review inventory system that provides several lead-time options to its customers. The inventory replenishment lead time is a multiple of the inventory review cycle. Customers are classified into two groups: short lead-time customers requiring the product immediately and long lead-time customers who allow the supplier the flexibility to deliver immediately or in the nex...

This article outlines a hybrid method, incorporating multiple techniques into an evaluation process, in order to select competitive suppliers in a supply chain. It enables a purchaser to do single sourcing and multiple sourcing by calculating a combined supplier score, which accounts for both qualitative and quantitative factors that have impact on supply chain performance. Keywords—Analytic hi...

Traditional sourcing arrangements for after-sales support of capital-intensive products such as airplanes, weapons systems, and manufacturing equipment have centered around physical assets. Typically, customers would pay the supplier of maintenance and repair services (usually the product manufacturer) for the resources, such as spare parts, that were needed to maintain the products. In recent ...

An effective supplier selection process is very important to the success of any manufacturing organization. The main objective of supplier selection process is to reduce purchase risk, maximize overall value to the purchaser, and develop closeness and long-term relationships between buyers and suppliers in today’s competitive industrial scenario. The literature on supplier selection criteria an...

A decades of offshoring production across the world, companies are rethinking their global networks. Local sourcing is receiving more attention, but it remains challenging to balance the offshore sourcing cost advantage against the increased inventories, because of its longer lead time, and against the cost and (volume) flexibility of each source’s capacity. To guide strategic allocation in thi...
