Reinforcement Learning (RL) can solve practical sequential decision problems, even when structures of the problems are less understood. However, some sequential decision problems intrinsically have structural parts that are easily to formulate and distinguish from less understood parts. Exploiting this knowledge may help improve performance of RL. This study proposed and investigated an approac...

Inventory control in a supply chain is crucial for companies desiring to satisfy their customers demands as well as controlling costs. This paper examines specifically supply planning under uncertainties in MRP environments. Models from literature that deals with random demand or lead time uncertainties are described and commented. Promising research areas emerge from this survey. It appears th...

The development of control-oriented decision policies for inventory management in supply chains has received considerable interest in recent years, and demand modeling to supply forecasts for these policies is an important component of an effective solution to this problem. Drawing from the problem of controlrelevant identification, we present an approach for demand modeling based on data that ...

We consider a stochastic inventory control problem in which a buyer makes procurement decisions while facing periodic random demand and two supply sources, namely, a long-term contract supplier and a spot market. The contract between the buyer and the supplier partially shields the latter from the vicissitudes of the spot market, in that the price paid by the buyer to the supplier is only parti...

This paper considers a concurrent pricing and inventory control problem in a stochastic and periodic review setting. Demand in a period is random and depends on the posted price. Other than holding and backlogging costs, the system incurs stock-replenishment costs that consist of both variable and fixed components. At the beginning of each period, a simultaneous decision has to be made on stock...

Store X is a store that sells muslim fashion products. There phenomenon often occurs in one of X's branches, such as the shortage jetblack hijab products stock. This results company's loss opportunity to gain profit and has an impact on high inventory costs. Based this, it known X’s branches does not yet have good system, so necessary apply optimal methods minimize study uses quantitative appro...
