Abstract

Control systems for logistic and transport systems are among the most complex control systems in existence. Currently control systems are only fully tested at the shop floor after commissioning. This means a lot of costly failures occur at the startup stages of control systems. The goal of this paper is to describe the extended role that simulation can play in evaluating of fully automated logistic systems and their control systems before commissioning. We followed a three-step approach in evaluating both logistic and logistic control systems. A simulated control system was used to control simulated, emulated, and real prototypes of logistic resources. Three different simulation packages have been used; Simple++, AutoMod, Arena. The control system was implemented in all three simulation packages to control logistic resources at the Connekt TestSite. The TestSite is a special laboratory for testing new technologies in logistic automation.
