Simultaneous production planning of make-to-order (MTO) and make-to-stock (MTS) products using simulation optimization. Case study: Soren Restaurant

Abstract

AbstractCurrently, due to the high quality of foods and services, some restaurants are moving towards service development by increasing production capacity, restaurant salon capacity, and prepared productions for quick response. However, the investment priority sectors for development are not clear. Restaurant planning, due to the lack of stable demands, is very difficult and not possible by means of mathematical models. Accordingly, in this paper, a method based on discrete event simulation was used to simulate the processes of order receiving, raw materials warehousing, and production in the kitchen of a five-star restaurant in Tehran. Important parameters from the perspective of restaurant management were optimized using design of experiments. Numerical results showed that, in accordance with the geographical conditions and public interests in traditional foods, the increase of restaurant salon capacity has higher priority and could lead to increased net profit. Additional studies revealed that to incr...
