Uncertain demand is one of the most important uncertainties in supply chain management. Different from the traditional methods, such as dynamic inventory control, estimation of demand, we propose to apply postponement strategy to treat uncertain demand in the process of distribution in supply chain. Postponement has been appreciated in recent decades, mainly in manufacturing period of realizing...

In production planning (PP) periods with excess capacity and growing demand, the manufacturers have two options to use the excess capacity. First, it could do more changeovers and thus reduce lot sizes, inventories, and inventory costs. Second, it could produce in excess of demand in the period and build additional inventory that can be used to satisfy future demand increments, thus delaying th...

Considering the supply chain consists of one supplier and two retailers, we construct the system’s dynamic models which face stochastic demand in the case of non-lateral transshipment (NLT), unidirectional lateral transshipment (ULT) and bidirectional lateral transshipment (BLT). Numerical example simulation experiments of these models were run on Venple. We adopt customer demand satisfaction r...

An important phenomenon in supply chain management, known as the bullwhip effect, suggests that demand variability increases as one moves up a supply chain. This paper examines the influence of different replenishment policies on the occurrence of the bullwhip effect. The paper demonstrates that certain replenishment policies can in themselves be inducers of the bullwhip effect, while others in...

The two objectives of this project were to develop an understanding of the challenges and opportunities of the supply chain of a family of currently marketed products manufactured overseas and distributed/sold worldwide and to increase the agility of the supply chain while achieving a target service level of 99% and maintaining or decreasing costs. A model was created to explore the current sup...

Rumor spreading is an important factor resulting in supply chain demand disruption. A supply-chain demand change prediction model is developed based on a new rumor spreading model, Susceptible-Infective-Isolated-Immune (SI2I) model. In this model, the impact of rumors on demand can be quantitatively reflected by the proportion of ignorants and immunes in the population.

one effective method for improving the performance of supply chain is making coordination among members of supply chain. this paper studies the subject of coordination of supply chain by using an insurance contract. the supply chain consists of one-manufacturer and one-retailer that the retailer is faced with potential demand and returning of goods from customer. acceptance of goods returned is...

This paper aims to examine integration of supply chain and demand chain in emerging markets. We present a research model of demand and supply chain integration which responds to customer’s needs through the integrated information flows. Integration of demand and supply chain synchronizes the key processes in terms of frontend development, product planning, product design, procurement, manufactu...

The bullwhip effect is defined as the distortion of demand information as one moves upstream in the supply chain, causing severe inefficiencies in the whole supply chain. Although extensive research has been conducted to study the causes of the bullwhip effect and seek mitigation solutions with respect to several demand processes, less attention has been devoted to the ...
