recently the concept of facility efficiency, which defined by data envelopment analysis (dea), introduced as a location modeling objective, that provides facilities location’s effect on their performance in serving demands. by combining the dea models with the location problem, two types of “efficiencies” are optimized: spatial efficiency which measured by finding the least cost location and al...

We develop a general method for cost-sharing that is approximately budget balanced and group strategyproof. We use our method to design cost sharing mechanisms for two NP-complete problems: metric facility location, and single source rent-or-buy network design. Both mechanisms are competitive, group strategyproof and recover a constant fraction of the cost. For the facility location game our co...

Dispersed manufacturing achieves the greatest cumulative competitive advantage by dissecting a supply chain and assigning each process to an optimal location. Dispersed manufacturing has been an integral part of global manufacturing in China. This paper presents a bi-objective model for the supply chain design of dispersed manufacturing in the context of rising business operating costs in coast...

The facility location problem in a market environment where other similar facilities are already activated has been studied extensively in the international bibliography. What has not been materialized however, with only a few incomplete exceptions, is software specialized on the specific problem. Given the huge number of models of the problem, the even greater number of their solution methods ...

We consider a competitive facility location problem with two players. Players alternate placing points, one at a time, into the playing arena, until each of them has placed n points. The arena is then subdivided according to the nearest-neighbor rule, and the player whose points control the larger area wins. We present a winning strategy for the second player, where the arena is a circle or a l...

We consider a competitive facility location game on a network in which consumers who are located on the vertices wish to connect to the nearest facility. Knowing this, each competitor locates a facility on a vertex, trying to capture the largest-possible market share. Focusing in the two-player case, we study conditions that guarantee the existence of a pure-strategy Nash equilibrium in this fi...
