Voronoi game presents a simple geometric model for Competitive facility location problems with two players. Voronoi game is played by two players known as White and Black, they play in a continuous arena. In the one-round game, White starts game and places all his points in the arena then Black places her points. Then the arena is divided by distance between two players and the player with the ...
In this paper, there are two competitors in a planar market. The first competitor, called, the leader, opens new facilities. After that, the second competitor, the follower, reacts to the leader’s action and opens r new facilities. The leader and the follower have got some facilities in advance in this market. The optimal locations for leader and follower are chosen among predefined candida...
In recent years, the green supply chain has become a key strategy for the competitiveness of organizations, where the reverse and closed-loop supply chains are one way to achieve it. In the current competitive environment, the closed-loop supply chain helps reduce costs by re-using recyclables and reducing environmental pollution by reducing waste and extending product life. In this study, a cl...
In this article we focus on approximation algorithms for facility location problems with subadditive costs. As examples of such problems, we present two facility location problems with stochastic demand and exponential servers, respectively inventory. We present a (1 + , 1)-reduction of the facility location problem with subadditive costs to a soft capacitated facility location problem, which i...
In this paper, some distributed approximation algorithms for uncapacitated facility location problem and fault-tolerant facility location problem are summarized, respectively. The worst-case run time of the distributed version of the uncapacitated facility location problem is ( ) O n , where n is the number of network nodes. In addition, the approximation approach for the fault-tolerant facilit...
We present e cient algorithms for two problems of facility location. In both problems we want to determine the location of a single facility with respect to n given sites. In the rst we seek a location that maximizes a weighted distance function between the facility and the sites, and in the second we nd a location that minimizes the sum (or sum of the squares) of the distances of k of the site...
Plants, distribution centers, and other facilities generally function for years or decades, during which time the environment in which they operate may change substantially. Costs, demands, travel times, and other inputs to classical facility location models may be highly uncertain. This has made the development of models for facility location under uncertainty a high priority for researchers i...
In this paper, we consider the problem of “importance sampling” from a high dynamic range image motivated by a computer graphics problem called image-based lighting. Image-based lighting is a method to light a scene by using real-world images as part of a 3D environment. Intuitively, the sampling problem reduces to finding representative points from the image such that they are in higher densit...
