Supply chain transportation operations often account for a large proportion of product total cost to market. Such can be optimized by solving the Logistics Service Network Design Problem (LSNDP), wherein logistics service provider seeks cost-effectively source and fulfill customer demands products within multi-echelon distribution network. However, many industrial settings yield instances LSNDP...

Supply chain designs are constrained by the cost-service trade-off. Cost minimization typically leads to physically efficient or lean supply chains at the expense of customer responsiveness or agility. Recently, the concept of leagility has been introduced. Research on leagility, defined as the capability of concurrently deploying the lean and agile paradigms, hinges heavily on the identificati...

There has been a lot of problems for Universities that the main problems of the students are obliged to pay high fees for education and also inability of university to provide appropriate services in terms of quality and quantity of the students. These two factors cause psychological and even physical problems in the country's students an after a while their motivation for continuing education ...

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 aims to evaluate inventory cost of a two-echelon serial supply chain system under vendor managed inventory program with stochastic demand, and examine the effect of environmental factors on the cost of overall system. for this purpose, we consider a two-echelon serial supply chain with a manufacturer and a retailer. under vendor managed inventory program, the decision on inventory le...

We consider a multi-stage production/distribution supply chain subject to stochastic demand. We formulate an optimization problem to determine where to place decoupling inventories, so-called strategic inventories, across the supply chain so as to minimize inventory holding costs subject to a service constraint for satisfying customer demand. We assume demand is normally distributed. For each s...

This paper studied pricing, service level, and production quantity decision problems in a supply chain with one manufacturer and one retailer under demand and production cost disruptions. The joint impact of demand and production cost disruptions on optimal pricing, service level, and production decisions in centralized and decentralized supply chain was analyzed, respectively. By solving the o...

We consider a multi-product serial two echelon inventory system with stochastic demand. Inventories at the downstream location are replenished periodically using an automatic ordering system. Under vendor managed inventory strategies the upstream stage is allowed to adapt these orders in order to benefit from economies of scale. We propose three different VMI strategies, aiming to reduce the or...

We consider customer response time minimization in a two-echelon supply chain system with stochastic demand where the first echelon consists of one production plant and the other of one retailer. Traditionally models of this type only seek to minimize traditional operating costs. However, because of the highly competitive nature of the market, it is also essential for the manufacturer to respon...
