We assume that m facility units (hospital, bank, post office, fire department, police station, bus station, etc.) are requested to be established for n cities which are on the same line. We have to choose m cities where the facility units will be established such that total distance from all cities to nearest facility units is minimum. Here, it is supposed that the person who is in the city whi...

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

Unlike other problems found in the oil industry, the allocation of compressors to gas-lifted oil wells lacks formal models and algorithms capable of delivering globally optimal assignments. To this end, this paper casts the compressor allocation problem as a facility location problem. Owing to the special structure of the target problem, an efficient (polynomial time) algorithm is conceived by ...

This paper presents a fault location technique for transmission lines with minimum current measurement. This algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. These current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...

This paper describes new methods for maintaining a point-location data structure for a dynamically changing monotone subdivision S. The main approach is based on the maintenance of two interlaced spanning trees, one for S and one for the graph-theoretic planar dual of S. Queries are answered by using a centroid decomposition of the dual tree to drive searches in the primal tree. These trees are...

network location models comprise one of the main categories of location models. these models have various applications in regional and urban planning as well as in transportation, distribution, and energy management. in a network location problem, nodes represent demand points and candidate locations to locate the facilities. if the links network is unchangeably determined, the problem will be ...
