Abstract: As an important part of fast food restaurant catering management, the restaurant catering process is studied. An Matlab software is used to analyze customer arrival time and service time, and a queuing theory model is set up. Queuing system model is programmed by Lingo software, to test the necessity of improving catering process. And using an industrial engineering method, the unreasonable process and procedures in the existing restaurant catering are improved, a new catering process developed, the improved standard time worked out, and the best number of service desk system determined. The optimal design scheme is feasible, and provides some technical guidance to other fast food restaurants on catering management.

Key words: catering process, queuing theory, Matlab software, Lingo software
