## Generalized Assignment Problem to Minimize Emergency Evacuation Routing in Istanbul Grand Bazaar

#### İlkay Saracoglu [1] , Gül Yücel [2]

In this study, the exit door assignment problem was discussed to determine route with the shortest distance and least density for the users of  Istanbul Grand Bazaar in case of a emergency. The evacuation plan was considered as Generalized Assignment Problem (GAP) which is 0-1 mixed integer programming model. The components of evaluation model consist of the length, area, user density as well as the streets in Grand Bazaar and their connection with exterior. In the study, 12 of doors in Grand Bazaar which are directly opened to intracity roads and 15 nodal points among junction points which are related to these doors were taken in consideration. A route is suggested with the aim of ensuring a safe evacuation at minimum density and in the shortest time in case of any emergency.  Grand Bazaar has more than one hundred thousand visitors daily depending on the season due to its characteristics of being a the historical trade center feature. Based on the study results, it is foreseen that there will be density at some exit doors in cases of emergency. Any evacuation plan in case of emergency must evaluate these routes and to take necessary physical precautions should be taken. At the same time, this evaluation may constitute a basis for improvement works devoted to use of other doors as well.
