This paper studies the coordination issue of a supply chain consisting of one retailer and two suppliers, amain supplier and a backup supplier. The main supplier’s yield is subject to disruption and the retailer faces a random demand. We determine the retailer’s optimal ordering policy and the main supplier’s production quantity that maximize expected profit of the centralized supply chain. We ...

In this paper, we study demand disruption in service supply chain with a client and a vendor. We find the positive demand disruption worse off the double marginalization under wholesale contracts. To address the challenge, we propose a two-part tariff contract under which, the client pays the vendor a fixed fee besides the wholesale price if the service rate was met. The results show the channe...

Supplier selection is one of the most critical activities of purchasing management in supply chain and managers increasingly face sourcing decisions of how to selected suppliers. This paper illustrates the development of a sourcing decision that provides support for the buyer firm in supply chain.The models developed here, involved selecting between single and dual sourcing. Outside and local s...

The recent rise in a number of calamities and terrorist acts has brought much attention to the vulnerabilities of supply chains. Having passed through many hands that span continents and entities, the reliability and timeliness of freight delivery become increasingly difficult to be assessed. Particularly, at seaports which is an indispensible node in global supply chains and where complex sea ...

Supply chain design models in the literature typically assume that facilities never fail. However, in the real world cases facilities are always subject to disruptions of various sorts due to natural disasters, strikes, machine breakdowns, power outages, and other factors. This paper presents an integrated supply chain network design model with the consideration of facility disruptions. Specifi...

Purpose: The main purpose of this article is to explore the trade-off between ordering policies and disruption risks in a dual-sourcing network under specific (or not) service level constraints, assuming that both supply channels are susceptible to disruption risks. Design/methodology/approach: Stochastic newsvendor models are presented under both the unconstrained and fill rate constraint case...

At the strategic level, closed-loop supply chain (CLSC) management involves long-term decisions regarding the location and capacity allocation of forward/reverse logistics facilities, the assignment of products to facilities, and the distribution of products between facilities and their end users or suppliers. Both demand and return handling must be taken into account, and the overall problem b...
