Most supplier selection models consider the buyer’s viewpoint and maximize only the buyer’s profit. This does not necessarily lead to an optimal situation for all the members of a supply chain. Coordination models have been developed to optimize the entire supply chain and align the decisions between its entities. Little research has been done on the application of these models in the supplier ...

Modern business environment focuses on improving the operational efficiency of supplier, retailer and customers through integrating their inventory. Although a smoothly running integrated inventory system is ideal, the reality is to deal with imperfectness in transportation. In actual production environments, inventory items are not perfect and defectiveness occurs in random process.  In this p...

Supplier competition and investment of effort are important concerns in supply base design. They are affected not only by the number of suppliers, but also by their capacity profile. This paper studies supply base design in terms of the number and capacities of suppliers, considering both supplier competition and investment of cost-reduction effort. We analyze a buyer who invests in capacities ...

supplier selection is one of the critical activities for firms to gain competitive advantage and achieve the objectives of the whole supply chain. in this paper based on a dea-topsis method for madm problems a flexible strategy for supplier selection is introduced

When designing a sourcing strategy in practice, a key task is to determine the average order rates placed to each source because that affects costs and supplier management. We consider a firm that has access to a responsive near-shore source (e.g., Mexico) and a low-cost offshore source (e.g., China). The firm must determine an inventory sourcing policy to satisfy random demand over time. Unfor...

This paper considers the joint supplier selection, replenishment and manufacturing control problem in a dynamic stochastic context. This problem is characterized by conflicting interests between suppliers, the manufacturer, and clients, which raise the need for coordination and information sharing. This paper contributes to the discourse mainly by developing and resolving an integrated mathemat...

We study the decision of a manufacturer (buyer), expecting new sourcing opportunities in the future, to select between a sole and a second sourcing mechanism for a non-commodity component. In a sole sourcing mechanism, the buyer commits to source from the current supplier. In a second sourcing mechanism, the buyer keeps the option open to source from a new supplier in the future. For a buyer th...

This research proposes a mathematical model in piecewise objective integer with quadratic programming to accommodate discount purchase, holding and transport costs on an integrated inventory control supplier selection problem. The proposed can be used determine the optimal decision, specifically, quantity of product ordered by decision maker stored should have minimal effect total cost. To eval...

Supplier selection is a multiple-attribute decision-making (MADM) problem. Since the decision makers (DMs) such as preferences on alternatives or on the attributes of suppliers are often uncertain, supplier selection becomes more difficult. Grey theory is one of the methods used to study uncertainty, being superior in the mathematical analysis of systems with uncertain information. In this pape...

When demand exceeds supply, retailers hedge against shortages by placing multiple orders with multiple suppliers. This artificial growth in orders can severely affect suppliers, creating excess capacity, excess inventory, low capacity utilization, financial and reputation losses. This paper contributes to the understanding of order amplification caused by shortages, by providing a comprehensive...
