This paper deals with the food flow for intercontinental KLM flights. The aim of this research is to design a framework to optimize the processes of food assembly and subsequently apply the framework to increase the throughput time at the intercontinental department of KLM Catering Services. A discrete event simulation model is created to compare key performance indicators for different design alternatives. In this simulation model different amount of equipment is handled together with different settings for a robot. With the use of this simulation model a combination of design alternatives is proposed.
