This paper considers a buyer who has to decide whether to select a single or two sources of supply for a homogeneous product. The production processes of the suppliers are subject to learning effects, which reduce the production costs and increase the production capacities of the suppliers. This, in turn, enables the suppliers to reduce the sales price, which results in lower acquisition costs ...

This paper studies split-award procurement auctions where a buyer can either divide full production among multiple suppliers or award the entire production to a single supplier. The literature shows that single sourcing usually dominates multiple sourcing. This paper challenges the “winner-takes-all” argument. In a framework of generalized second-price auctions with pre-auction investment, we s...

This paper deals with the optimal allocation of demand across a set of suppliers given the risk of suppliers’ failure to deliver. We consider items that are used in multiple facilities (demand points) and that can be purchased from multiple suppliers with different cost and reliability characteristics. Suppliers have production flexibility that allows them to deliver a contingency quantity in c...

In this paper I develop a theoretical model and analyze the relationship between two bilateral monopolies, investments decisions of downstream …rms regarding technologies speci…c to suppliers, and suppliers’ incentives to merge. The paper discusses the concept of the choice of dedicated versus ‡exible production technology in the context of bilateral monopolies. I aim to answer two questions. F...

Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...

In last decades, mobile factories have been used due to their high production capability, carrying their equipment and covering rough and uneven routes. Nowadays, more companies use mobile factories with the aim of reducing the transportation and manufacturing costs. The mobile factory must travel between the suppliers, visit all of them in each time period and return to the initial location of...

‎This paper proposes a multi-supplier multi-product inventory model in which the suppliers have unlimited production capacity, allow delayed payment, and offer either an all-unit or incremental discount. The retailer can delay payment until after they have sold all the units of the purchased product. The retailer’s warehouse is limited, but the surplus can be stored in a rented warehouse at a...
