A Study on Stock Location Management for Warehouse Layout

Abstract

This study investigates how to seek an optimal allocation for a wafer warehouse in Taiwan The wafer is a fairly critical technological products nowadays Due to the fact that every 3C product needs the wafer such as mobile phones tablets smart watches and even the car keys nearly all of the products have to work functionally with it The management of the warehouse includes storage picking and shipping Considering the constant and rapid changes of technology products shipping is therefore regarded as the priority in the management of the warehouse The current practice is inefficient since the staff sort wafers by the names of customers which directly creates the extra movement and wastes much time Picking is a crucial path of shipping In order to improve the efficiency of picking a new allocation to shorten the route of picking is a necessary issue Here we formulate an integer linear program which involves the stock unit and the frequency Since the layout of warehouse is like a chessboard we adopt the Manhattan Distance to calculate the picking route and solve it by a state-of-the-art optimization solver on the computer We have examined the mathematical model with the authentic data and apply the systematic simulation to present how the optimization solver assigns the location We can therefore conclude that the mathematical model efficiently reduces the picking route which is not only useful but also easy
