It is scientifically challenging to determine the inventory level all through the supply chain in such a way that the desired objectives such as effectiveness and responsiveness of the supply chain system can be obtained. Simulation is a means for solving various problems which cannot be solved by regular exact models such as mathematical ones due to their complexity. The present paper is aime...

We study stochastic inventory planning systems with lost sales and censored demand under stationary and non-stationary settings. Contrary to classical inventory theory, we assume that no knowledge of demand is initially available, and lost sales in each period are unobservable. We take a non-parametric approach and propose adaptive inventory policies that generate a sequence of ordering decisio...

this paper is a research on the ordering planning of a supply chain with one supplier, multi buyer and multi deteriorating items. items have fixed life time and expire dates. the ordering period is taken as variable and must be computed the proposed models. the problem is studied via two different approaches the first is the joint replenishment, based on the hwang and chew's model [3] and ...

Poor information and data quality cost organizations in lost sales and revenue due to scrap and rework and contributes to ineffective decision-making by senior management. In a governmental non-profit environment such as the Naval Inventory Control Point (NAVICP), the data resident within the operational databases and systems is the precious commodity that connects the organization with its cus...

In the supply chain by the composition of the supplier and the retailer, the supplier offers products to the retailer for sales while the retailer affects the sales outcome by his effort which is divided into two dimensions. One is for the short-term sales task and the other is for the long-term sales task. For the long-term development of the enterprise, the supplier wants to inspire the retai...
