Optimization of Time and Cost in Establishment of Temporary Accommodations after the Crisis

There is a long history of occurrences for events and natural &/ un-natural crisis in Iran. Some natural crisis are as earthquake, flood, storm, reaper, landslide and fire. Generally, in every crisis the homes and accommodations of majority of people are damaged and some people getting into financial and psychological damages. Temporary accommodation of injured people in every crisis is the main task for the authorities of each country. Temporary accommodation operation should be conducted with due observance on the rules such as time, cost and operation of the site. Nowadays, much progresses has been conducted in the world in building of the temporary accommodations and then construction velocity and quality were improved. In this research, Iran’s country conditions were studied and optimization of time and cost of building of temporary accommodations were investigated using both of particle size optimization algorithm (PSOA) and MATLAB software. The aim of research was optimal distribution of demographic blocks in residences so that firstly, do not exceed the capacity of any settlement and secondly, the minimum distance and cost for moving the population is spent. The obtained results showed finally that for optimization of time and cost of operation which demographic block should be moved to what accommodation. Regarding to the limited capacity of every settlement, the population overflow for some demographic blocks should be moved to several settlements. Some advantages for settlements structures compared to others, are as fast installation, low cost, and convenient storage.
