A service supply chain optimization model with application to tourism industry Min Kyu Hwang1 and Young Hae Lee2* Department of Industrial and Management Engineering Hanyang University S. Korea 1 munggu@hanyang.ac.kr 2* yhlee@hanyang.ac.kr Abstract: The service industry is getting bigger in all the countries. In spite of this situation, the researches focused on service supply chain are not much. In particular, the studies related to service supply chain optimization rarely exist. This study deals with service supply chain optimization model with application to the tourism industry. In this study the structure of tourism supply chain based on a real tour industry is established and an optimization model of the tourism supply chain will be developed which reflects some characteristics of the service. In order to develop the mathematical model, mixed-integer nonlinear programming is used. And the developed model is solved by a meta heuristics method. Key words: service supply chain, optimization, mixed-integer nonlinear programming, meta heuristics method * Corresponding Author
