Estimation of the cost function of a two-echelon inventory system with lost sales using regression
Multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. In this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. We have assumed the demand i...
متن کاملCost Evaluation of a Two-Echelon Inventory System with Lost Sales and Approximately Normal Demand
The inventory system under consideration consists of one central warehouse and an arbitrary number of retailers controlled by a continuous review inventory policy (R;Q). Independent Poisson demands are assumed with constant transportation times for all retailers and a constant lead time for replenishing orders from an external supplier for the warehouse. Unsatis ed demands are assumed to be los...
متن کاملParametric replenishment policies for inventory systems with lost sales and fixed order cost
In this paper we consider a single-item inventory systemwith lost sales and fixed order cost. We numerically illustrate the lack of a clear structure in optimal replenishment policies for such systems. However, policies with a simple structure are preferred in practical settings. Examples of replenishment policies with a simple parametric description are the (s, S) policy and the (s,nQ) policy....

متن کاملConstrained backorders inventory system with varying order cost: Lead time demand uniformly distributed
Probabilistic model; Inventory; Varying order cost; Holding cost; Lead-time demand; Uniform distribution; Safety stock Abstract This paper discusses the probabilistic backorders inventory system when the order cost unit is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead time deman...
