Integrating various suppliers to satisfy market demand is of great importance for e ective supply chain management. In this paper, we consider the ODE-PDE model of supply chain and apply a classical explicit fourth-order Runge-Kutta scheme for the related ODE model of suppliers. Also, the convergence of the proposed method is proved. Finally a numerical example is studied to demonstrate the acc...

in this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified. providing a measure for bullwhip effect that enables us to analyze and reduce this phenomenon in supply chains with two products is the basic purpose of this paper. demand of products is presented by the first order vector autoregr...

This paper studies the effects of information sharing strategies on supply chain performance. We first consider four common types of information sharing strategies for a supply chain of a single product: (1) order information sharing where every stage of the supply chain only knows the orders from its immediate downstream stage; (2) demand information sharing where every stage has full informa...

Demand fluctuations in the supply chain lead to uncertainty in inventory policy and thereupon the inventory costs increase. This paper considers the impact of forecasting on the demand variation in a serial three-stage supply chain including a retailer, a manufacturer and a supplier. Four forecasting methods are considered and demand variations evaluated as bullwhip effect measure. We use analy...

Growing global demand for energy, result in depletion of easily access source of fossil fuels. To fulfillment of this huge demand, oil and gas industry expanded to develop offshore oil and gas reservoirs in recent years, which made environmental management challenging. IRAN owns one of the biggest offshore gas reservoir in PERSIAN GULF with high geopolitical and financial importance. Along the ...

This paper evaluates three component commonality strategies in supply chain environment: Distinctive Part (DP), Pure Component Commonality (PCC), and Mixed Component Commonality (MCC) strategies. DP is where all products consist of distinctive parts and no common component is used, while PCC is where one or more parts from different products are completely replaced by common components. In MCC,...

Demand forecasting; which sound basis for decision making process, is among the key activities that directly affect the supply chain performance. As the demand pattern varies from system to system, determination of the appropriate forecasting model that best fits the demand pattern is a hard decision in management of supply chains. The whiplash effect can be express as the variability of the de...
