This paper develops a model for the closed-loop supply chain network design with disruption risk. By considering supply disruption, two factors including extra inventory and lateral transshipment are used as resilience strategies. The main purpose is to reduce the supply chain costs due to the location decisions, quantity of products between different levels and lost sale. Disruption in a suppl...

This research considers a supply chain under the following conditions: (i) two heterogeneous suppliers are in competition, (ii) supply capacity is random and pricing is endogenous, (iii) consumer demand, with and without an intermediate retailer, is price dependent. Specifically, we examine how uncertainty in supply capacity affects optimal ordering and pricing decisions, supplier and retailer ...

The main purpose of this research was to build on Fisher’s (1997) seminal article. First, it expands on the Fisher framework by empirically establishing the link between the firm’s environmental characteristics and the firm’s level of supply chain fit (SCF). The results indicate a negative relationship between environmental uncertainty and SCF indicating that, as the level of environmental unce...

We study the competition of two supply chains which are subject to supply uncertainty. Each supply chain consists of a supplier and a retailer. The retailers engage in Cournot competition by determining order quantities from their exclusive suppliers. The suppliers may not be able to fulfill the retailer orders at all time due to various causes. We examine the decisions of the suppliers and ret...

REQUIRED) Uncertainty is a major problem in any supply chain. Inventory and excess capacities used to cope with uncertainty are significant cost drivers. Advanced information systems have been employed to support information exchange along the supply chain and were successful in synchronizing supply and demand and downsizing inventories. However, close cooperation requires mutual trust as a bas...

This paper investigates the impacts of both the demand uncertainty and the supply disruption probability on the decisions of two sourcing strategies: one is dual sourcing and the other is single sourcing with contingent supply. The expected profit functions and the optimal decisions of the buyer are derived and compared. Then sensitivity analysis is given through numerical examples. Explicit in...

Supply chain is an organized combination of inbound logistics, production plants and multiechelon distribution network. Decentralized distribution networks are common and prone to exogenous and endogenous uncertainties. Information uncertainty from the downstream customer and material uncertainty from the upstream supplier makes the supply chain behavior more complex. Previous attempts made to ...

this paper presents a theoretical model in order to determine tile expected rate of durable good`s supply over time. the social plaliner maximizes tile sum of the discount ed net benefit. subject to the stochastic fluctuation in the stock of durable goods. it turns out that a social planner increases the expected rate of supply since uncertainty increases the user's loss from the view poin...

We study the strategic design of a supply chain for new products. Planning a supply chain for a new product requires addressing both uncertainties in demand and cost and changes in market conditions over time. We develop a mathematical programming model for new products that includes both financial viability and robustness relative to uncertainty. An example based on a Fortune 200 company’s eff...

Supply Chain Management (SCM) refers to the problems where the decisions of supply, production and demand are integrated in a single framework. A typical supply chain faces uncertainty in terms of supply, production and demand. Therefore, SCM is largely about managing uncertainty and risks. This paper introduces a simulationand optimisation-based decision support system that helps the scheduler...
