A new model for Hierarchical Healthcare Facility Location Crisis Nooshin Bajool n bajool@in iut ac ir Date of Submission Department of Industrial Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Mehdi Alinaghian alinaghian@cc iut ac irAbstractHealth care centers are of the most urban users which are directly involved in supplying individual andsocial health Fast inexpensive and right on time access to these centers is of significant importance in anysociety particularly in urban society The main duty of programmers and decision makers in determiningurban optimal location of these centers is in the way that all urban population can have access to thesecenters easily In this research location problem of hierarchical health care facilities is considered Due to indefinite natureof demand a mathematical model relied on fuzzy credibility theory which represented the amount ofdemand as a triangular fuzzy variable Since Iran is among ten disaster prone countries and sixth seismic country though it is impossible tocompensate harms from different perspectives but it is possible to minimize harms by precautionary actionsand suitable programming in confronting of events For instance one the important strategies in order toimprove system s operation and to decrease delay in relief is location of health care centers in relief supplychain Strategic importance of this discussion from different social and economic perspectives expressesnecessities of paying attention to this problem In this research in facing with uncertainty in critical situation an optimization model depending uponmulvey model is offered This model includes determining health care and relief centers at different levelsand by different services Furthermore in order to help to injured people and to avoid congestion in hospitalsand medical centers there must be possibility of establishing temporary facilities and outpatients treatmentcenters to give initial emergency services also sending medical teams and equipment to these centers Since the considering problem is among NP complete problems cluster harmony search algorithm andtaboo search algorithm by using two strategies in a way that in the first strategy this algorithm is mixedwith variable neighborhood search algorithm are used to give solution Taboo search algorithm in twostrategies uses a simple mathematical model to initiate the initial solution In order to improve performanceof the algorithms in optimization problem Taguchi method is used The lower bound of Langrangeanrelaxation method is used to compare meta heuristic algorithms for large dimensional problems Infollowing some sample problems in small and large dimensions accidentally are generated and results ofexact solution and offered meta heuristic algorithms considered and compared together Results show thattaboo search algorithm the first strategy has better efficiency than harmony algorithm Keywords Hierarchical health care facility location problem fuzzy credibility theory Robustoptimization Harmony search algorithm Tabu search algorithm Variable neighborhood search algorithm lagrangean relaxation method
