Providing a combination Facility location model for locating critical and important facilities with consider of passive defense principles

One of the objectives defined in the facility location problem is dispersing facility location. On these issues, the goal is maximizing the distance between the facilities according to the constraints are available. These issues use in some cases location radio stations, schools, sales representatives and general location sensitive facilities considering passive defense principles have many applications. On the other hand the facilities operating on the principle of passive defense should be dispersed to each other, should be established in places where they can gain their mission correctly and coefficient error reduced. For considering this issue (coefficient of performance and reduce error candidate points) are suggested technique Data Envelopment Analysis with regard to criteria for choosing locations with efficient distribution model used. So in this paper a new multi-objective model for locating critical and important facility with consider of passive defense principles is presented.
