A Mixed-integer Linear Programming model is proposed to determine the optimal number, location and capacity of the warehouses required to support a long-term forecast for a business with seasonal demand. Discrete transportation costs, dynamic warehouse contracting, and the handling of safety stock are the three main distinctive features of the problem. Four alternatives for addressing discrete ...

The Economic Order Quantity (EOQ) problem is a fundamental problem in supply and inventory management. In its classical setting, solutions are not affected by the warehouse capacity. We study a type of EOQ problem where the (maximum) warehouse capacity is a decision variable. Furthermore, we assume that thewarehouse cost dominates all the other inventory holding costs. We call this the EOQ-Max ...

In order to realize the intelligent management of a power materials warehouse, Internet Things based on wireless sensor networks (WSNs) is promising effective solution. Considering limited battery capacity nodes, optimization topology control and determination amount collected data are critical for prolonging survival time WSNs increasing satisfaction warehouse supplier. Therefore, in this pape...

Web cache technologies have been developed as an extension of CPU cache, by modifying LRU (Least Recently Used) algorithms. Actually in web cache systems, we can use disks and tertiary storages since access time of disks (or even online tapes) is still shorter than time required for retrieving web pages from origin severs. Thus, we can remove the restriction of cache size that has been the most...

This article will introduce an inventory model for deteriorating items under a ramp-type demand rate. In the sequel, preservation technology has appeared to reduce deterioration rate of items. The is considered time-dependent. Due demand, retailers may face complete and partial backlogged shortages. We suggest two-warehouse effect when retailer faces storage capacity problem. this model, it wou...

In this paper we shall discuss with the optimal ordering policy for two warehouse inventory model of non-instantaneous deteriorating items and stock-dependent demand. Here shortage is not allowed. Here the holding and deteriorating costs in both warehouses are different and assumed that the holding cost in the RW(rented warehouse) than in the OW(owned warehouse) the optimal solution are shown. ...

The study of agricultural product's inventory is significant to lower its logistics cost, reduce the waste during the logistics courses and guarantee its quality. Deteriorating items can be studied by the way of literature review according to time varying of demand, inventory shortage and deteriorating rate while multi-warehouse according to the number of renting warehouse, capacity and demand ...

In this paper, a supply chain model with power form stock-dependent demand rate is developed, incorporating the effect of learning and inflationary environment. In order to bring their research closer to reality, all the cost parameters involved in the model are considered fuzzy in nature. The demand rate is assumed to be a polynomial form of current inventory level in Own-warehouse. To display...

Using ProModel simulation language, a universal warehouse storage simulation model has been developed. Applications of the model have been executed with success to analyze the storage capacity and rack efficiency of a medium volume, low stock-keeping unit (SKU) warehouse and a medium volume, large SKU warehouse. The model is scaleable and can be modified to simulate any warehouse configuration,...
