| Concentrator site choice is a complicated system engineering, which directly related to the construction, operation concentrator during the period of economic benefits and social benefits, and other aspects. Site choice has been one of the hot issues research, and have achieved some results. However, the existing site choice method is still exists too poor, operability subjectivity, cannot satisfy the present defects dressing enterprise requirements, so study science reasonable site choice method is imperative.Paper systematically analyzed the influence factors of concentrator site choice, grey correlation method is used to determine the key factors. Based on the existing site selection method, analyzes the existing approach the shortage, and purposefully presents petri nets solve use time thinking site choice. Papers comprehensive cost, environmental protection, safety, constructs the three aspects of the evaluation index system of selecting sites. Based on the petri nets method using time established concentrator site choice model, and combined with model and calculation method of characteristics of ant colony algorithm, using adaptive to the site choice petri nets model is solved by time. Through the case analysis, fully demonstrates the petri nets site choice based on time method of the entirety, scientific and maneuverability,This paper proposes the concentrator petri nets based on time, site choice method system is dressing enterprise site choice of a kind of new ideas and methods, and this method system with existing universal applicability in other areas, the value of the site promotion.
