The Virtual Reality Concept for the Warehouse Simulation Model Implementation

This paper presents a method of warehouse simulation model implementation using concepts of virtual reality (VR). The basic idea is to compare the "real process" controlled by operator with his/her heuristics to the "virtual process" represented by a simulation model, controlled by the optimization algorithm. The optimization algorithm is based on a SD model of the warehouse and decision support module. The SD warehouse model represents the abstraction of "virtual process" and is considered as a model of a model. The state of the "virtual process" is controlled with the help of a decision support module and is compared with the state of the real process on the basis of actual information regarding the state of warehouse. This concept is useful for predictive model validation where the parallel observation of the actual system and virtual one takes place simultaneously, and for the optimization algorithm migration into practice.
