s-This paper further extends the existing cost model for a fixed-life perishable product in a two-echelon inventory problem into the net profit model. The extended model is subsequently evaluated by comparing its results with those obtained from OptQuest, a commercial simulationoptimization package. Within a limited but reasonable time, the comparative results do not show a significant improvem...

Inventory control is one of the most important issues in supply chain management. In this paper, a three-echelon production, distribution, inventory system composed of one producer, a set of wholesalers and retailers is considered. Costumers' demands can be approximated by a normal distribution and the inventory policy is a kind of continuous review (R, Q). In this paper, a model based on stand...

W consider a two-echelon inventory system with a capacitated centralized production facility and several distribution centers (DCs). Both production and transportation times are stochastic with general distributions. Demand arrives at each DC according to an independent Poisson process and is backlogged if the DC is out of stock. We allow different holding and backlog costs at the different DCs...

In this paper we consider a two-echelon supply chain system consisting of a supplier and a retailer. The supplier has an inventory system and a service unit to process the orders received from the retailer. Demands arrive to the retailer according to a Poisson process. Both supplier and retailer apply one-for-one ordering policy. The supplier’s lead time and the service time of his service unit...

We consider N-stage serial production/distribution systems with stationary demand at the most downstream stage. First, we study classical Clark-Scarf model with both average cost and discounted cost criteria. The optimal echelon base-stock levels are obtained in terms of only probabilistic distributions of leadtime demand. This analysis yields a novel approach for developing bounds and simple h...

Collaboration has been recognized as a significant process that holds the value creation opportunity in supply chain management. Evaluating the value of collaboration is thus necessary for developing the effective collaboration mechanisms. This paper presents the evaluation approach specifically focusing on the supply-side collaboration on inventory decisions between a supplier and a distributo...

This paper analyzes the manufacturers’ strategy of optimizing the direct rebate to the final customer and the wholesale price to a profit-maximizing retailer with a price-dependent stochastic demand. The manufacturer possesses full information about the cost and the functional relationship among demand, price and rebate, but may or may not know about the nature of the underlying demand uncertai...

In traditional supply chain models it is generally assumed that full information is available to all parties involved. Although this seems reasonable, there are cases where chain members are independent agents and possess different levels of information. In this study, we analyze a two-echelon, single supplier-multiple retailers supply chain in a single-period setting where the capacity of the ...

Identifying individual subsurface faults in a larger fault system is important to characterize and understand the relationship between microseismicity and subsurface processes. This information can potentially help drive reservoir management and mitigate the risks of natural or induced seismicity. We have evaluated a method of statistically clustering power spectra from microseismic events asso...
