EQUILIBRIUM FOR PROCUREMENT STRATEGY BETWEEN TRIAD COMPETITIVE SUPPLY CHAINS

Pricing decisions for complementary products of competitive supply chains

This study considers pricing, production and transportation decisions in a Stackelberg game between three-stage, multi-product, multi-source and single-period supply chains called leader and follower. These chains consist of; manufacturers, distribution centers (DCs) and retailers. Competition type is horizontal and SC vs. SC. The retailers in two chains try to maximize their profit through pri...

Competitive Equilibrium Analysis for Repeated Procurement Auctions

In this study, we conduct a competitive equilibrium analysis for the repeated (sequential) procurement auctions. We consider capacitated suppliers (bidders), each with a U-shaped cost function that captures the economies (and dis-economies) of scale in bidding quantity. Cases with both homogenous and non-homogenous bidders are considered in a symmetric incomplete information setting. First we a...

Retailer’s Procurement Strategy under Endogenous Supply Stability

In this paper, a dynamic model is presented to study retailer’s procurement strategy when supply stability is endogenously determined. The optimal supply stability as well as the optimal purchasing strategy are characterized with a quadratic cost function. Based on these models, the following findings are brought about. Firstly, when the difficulty level of building supply stability exceeds a c...

Scheduling to be competitive in supply chains

We assume an open supply chain environment where organizations in a globalized trading scenario can sub-contract out sub-tasks to other organizations through a contracting process. Manufacturers are assumed to award sub-contracts to bidding suppliers using an auction scheme. Of particular interest in this environment is the task scheduling strategies used by suppliers in response to manufacture...

Collaborative Procurement and Due Date Management in Supply Chains

An efficient Imperialistic Competitive Algorithm for the closed-loop supply chains considering pricing for product, and fleet of heterogeneous vehicles

 This paper investigates a pricing multi-period, closed-loop supply chains (CLSCs) with two echelons of producers and customers. Products are delivered to customers might be defective which are picked up and gathered in the collection center and will be fixed if it is possible and will be returned to the chain. Otherwise, they are sold as waste. This problem is determining price and distributio...
