Simulation Model and Analysis for Uncertain Demand and Replenishment Policies in Supply Chain
نویسندگان
چکیده
This paper describes a special purpose simulation model developed for analysing supply chain (SC) behaviour and performance in the presence of uncertainty. A SC is viewed as a series of facilities that performs procurement of raw materials, its transformation to intermediate and end-products, and distribution and sales of the end-products to customers. Uncertainties perceived in these SC data are described by imprecise natural language expressions and they are modelled by fuzzy sets. Also, this paper proposes the process of each object in SC and various replenish policies. The application of SC simulation in analysing and quantifying the effects of changing uncertainty in customer demand is discussed and illustrated by a numerical example.

Optimal replenishment and credit policy in supply chain inventory model under two levels of trade credit with time- and credit-sensitive demand involving default risk
Traditional supply chain inventory modes with trade credit usually only assumed that the up-stream suppliers offered the down-stream retailers a fixed credit period. However, in practice the retailers will also provide a credit period to customers to promote the market competition. In this paper, we formulate an optimal supply chain inventory model under two levels of trade credit policy with d...
متن کاملApplying queuing theory for a reliable integrated location –inventory problem under facility disruption risks
This study considers a reliable location – inventory problem for a supply chain system comprising one supplier, multiple distribution centers (DCs), and multiple retailers in which we determine DCs location, inventory replenishment decisions and assignment retailers to DCs, simultaneously. Each DC is managed through a continuous review (S, Q) inventory policy. For tackling real world conditions...
متن کاملDevelopment Model for Supply Chain Network Design by Demand Uncertainty and Mode Selection
It is necessary to consider the impact of demand uncertainty to model the comprehensive approach for supply chain network design. This paper presents four echelons, multiple commodity, and strategic–tactical model for designing supply chain network. Uncertain demand, transportation mode selection with lead time configuration has been considered. A numerical example has been implemented to verif...
متن کاملEffects of integrating physical and financial flows through a closed-loop supply chain network under uncertain demand and return
The impact of financial challenges on the profit of a supply chain, have caused the researcher to model the supply chain network by considering the operational and financial dimensions. Also, the establishment of a closed loop supply chain (CLSC) network has a high effect on economic profit. So, the purpose of this study is to design a stochastic closed loop supply chain network by considering ...
متن کاملCoordination of green supply chain network, considering uncertain demand and stochastic CO2 emission level
Many supply chain problems involve optimization of various conflicting objectives. This paper formulates a green supply chain network throughout a two-stage mixed integer linear problem with uncertain demand and stochastic environmental respects level. The first objective function of the proposed model considers minimization of supply chain costs while the second objective function minimizes CO...
