Configuring Simulation Models Using CAD Techniques: A New Approach to Warehouse Design

摘要

The research reported in this thesis is related to the development and use of softwaretools for supporting warehouse design and management. Computer Aided Design andSimulation techniques are used to develop a software system that forms the basis of aDecision Support System for warehouse design.The current position of simulation software is reviewed. It is investigated howappropriate current simulation software is for warehouse modelling. Special attentionis given to Visual Interactive Simulation, graphics, animation and user interfaces.The warehouse design process is described and common difficulties are highlighted.A Decision Support System (DSS) framework is proposed to give support during allthe warehouse design phases.The use of simulation in warehouse design is identified as being essential forevaluating different warehouse configurations. Several simulation models are used toshow that the warehouse systems special characteristics require a new way of definingthe simulation model and new modelling elements to represent the complex logic of awarehouse system.AWARD (Advanced WARehouse Design) is a data-driven generic model, developedto build warehouse simulation models. It uses Computer Aided Design (CAD)techniques for drawing the warehouse layout and configuring the simulation model.The user has no need for programming skills and a user-friendly interface makes iteasy to use. High resolution colour graphics and a scale drawing of the warehousemakest he dynamic display of the model a good representationo f the real system.Several examples illustrate the use of the AWARD system. The experience andadvantages of the AWARD approach is discussed and the extension of this approachto other areas is explored.
