Airline-catering plant material handling system analysis with simulation and scaled animation

The authors discuss the applications of simulation and scaled animation at Sky Chefs Inc., and particularly highlight the analysis of complex power and free (P&F) material handling systems (MHSs). Results of analysis related to the design and validation of the system are also presented. A detailed simulation model is developed with GPSS/H language for the P&F conveyor system for the Sky Chefs Miami facility. Graphic animation is interfaced to the simulation model with a general animation software PROOF. With the aid of PROOF, the scaled animation trace file generated from the GPSS/H simulation model made it possible to see the behavior and performance of the designed system in a realistic, smooth, and dynamic environment during the entire life cycle of the system´s development. Animation also gives the systems engineers operational experience with the system and improves the communications between internal/external supplies/customers
