| description | In this paper, a nonlinear model for locating service facilities is introduced in a competitive region. In the proposed model the factors of travel time, quality of service facilities and price are considered that are the most important effective factors in attracting and maintaining the customers in the competitive environments. For identifying the customers’ probabilistic behavior in selecting the competitor’s and entering firm’s facilities, the spatial interaction model and Logit function are used. Since the decision making for locating is not only based on the sale quantity and market demand captured and ignoring other important organizational goals such as minimizing the cost may provide problems in long term for firms, therefore in addition to the capturing demand, the fixed cost of locating is considered in the model that will provide better results in the real world problems. Due to the computational complexity, a genetic algorithm is developed for solving the model. The numerical results verify the performance of the proposed model and effectiveness of the genetic algorithm in solving it and show that the study of costumers’ probabilistic demand considering the factors of price, travel time and quality of service facilities has the major role in the increasing of sale and profit of the entering firm so that, in spite of selecting the most appropriate locations by the competitor, the sale and profit quantities of entering firm are more than the competitor’s, in the equal situation of price, quality and number of facilities. |
