Procurement Strategies with Unreliable Suppliers
We propose and analyze a general periodic-review model in which the firm has access to a set of potential suppliers, each with specific yield and price characteristics. Assuming that unsatisfied demand is backlogged, the firm incurs three types of costs: (i) procurement costs, (ii) inventory-carrying costs for units carried over from one period to the next, and (iii) backlogging costs. A procur...
متن کاملOnline Procurement Intermediaries with Differentiated Suppliers*
Industrial buyers who seek to procure inputs have the option of contracting the process out to procurement intermediaries. Many of these intermediaries now operate using Internet-based software to enhance the efficiency of their services. We develop a theoretical model of a buyer who wishes to procure an input from one of many differentiated suppliers. The buyer chooses between conducting the p...
متن کاملOptimal Pricing and Procurement Strategies in a Supply Chain with Multiple Capacitated Suppliers
The scenario considered in this paper is a supply chain with multiple suppliers, all of whom have limited capacity. The demand over a finite planning horizon is known, and an optimal procurement strategy for this multiperiod horizon is to be determined. We supplement this scenario with the entry of a new supplier who is looking to price their products competitively. A single pricing decision is...
متن کاملOptimal Procurement Auctions of Divisible Goods with Capacitated Suppliers
The literature on procurement auctions (reverse auctions) typically assumes that the suppliers are uncapacitated (see, e.g. Dasgupta and Spulber, 1990; Ankolekar et al., 2005; Chen, 2004; Che, 1993). Consequently, these auction mechanisms award the contract to a single supplier. We consider a model where suppliers have limited production capacity, and both marginal costs and the production capa...
متن کاملA Single Supplier Procurement Model With Random Yield
In this paper, we develop a procedure for selecting a supplier. Suppliers are characterized by their lead time, price and quality (random yield). Each purchased item is acceptable with a given probability and independent of the others. We assume the demands are deterministic with no set-up cost and backordering is allowed. For each supplier, an optimal ordering policy is developed. We prove the...
