We consider a single-facility location problem, where agents are positioned on the real line and partitioned into multiple disjoint districts. The goal is to choose (where public facility be built) so as minimize total distance of from it. This process distributed: positions in each district first aggregated representative for district, then one representatives chosen location. indirect access ...

Abstract The facility location of a competing firm in market has great importance supply chain management. two-stage competitive model formulates the decision process an entrant facing both and price competition. In this paper, we incorporated quantity as variable into with objective maximized profit. Sequential mode simultaneous were applied to simulate different behavior. We developed approxi...

In this paper we introduce a new facility location model, called backup multifacility location problem by considering the ideal radius for each customer. In this problem the location of clients are given in the plane. A radius is assigned to each client. We should find the location of new facilities, which some of them may fail with a given probability, such that the sum of weighted distances f...

Location Based Services (LBS) has become an important field of research with the rapid development of Internet-based Information Technology (IOT) technology and everywhere we use smartphones and social networks in our everyday lives. Although users can enjoy the flexibility, facility, facility and location-based services (LBS) with the Internet of Things, they may lose their privacy. An untrust...
