High Bay Storage Control System

Introduction

Vertical Storage Solutions (VSS) is a supplier of high bay pallet storage systems for warehouses. A high bay system is essentially a large shelving unit for storing pallets in a warehouse (Figure 1). Each set of shelves is separated from the next by a narrow aisle. Electrically operated cranes move along the aisles horizontally and up and down vertically in order to move pallets to shelf locations in the high bay system. Each crane can also move along the end of the shelving system so that it can move from aisle to aisle and to a loading area where pallets can be loaded onto and off the cranes. High bay systems are much higher than conventional pallet racking, which is designed to be accessible to fork-lift trucks. High bay systems often are built two or three storeys below ground level and may be several storeys high. The typical height of a high bay system may be 25 metres (80 feet).

VSS has an existing software package that controls its high bay systems and wants to rewrite it. The existing system is written in C and uses C-ISAM files to store data. The supplier of the C-ISAM libraries is discontinuing support, and VSS wants to move its system to a newer platform. The existing storage control system (SCS) interfaces to other warehouse management systems (WMS) through a series of text files that are transferred into a specific directory on the machine that runs the SCS. VSS want to change this interface so that other WMS can send messages to the SCS using SOAP-based web services.
