Approach for siting a support facility for transporting supplies in emergency cases in the Republic of Bulgaria
In this paper, the author determines the most suitable transportation location for intervention in a large scale disaster in the Republic of Bulgaria, by means of the Weber Problem and the Weiszfeld method. The objective is to minimise the cost of transporting emergency supplies across the country by locating a support facility, and thus reaching the area of event at the lowest possible cost. A brief description of the Weiszfeld method is provided in the paper. Further, using recent population data of both provinces and municipalities, the method is applied respectively to obtain the results. They were compared in terms of spatial correspondence and the final facility location was fixed. Erecting the supply site is recommended to help decrease the losses.No sponso
Iterative methodology on locating a cement plant
In this study, a cement plant location was determined by considering essential parameters such as the locations of resources and their importance in the manufacturing process. A crucial mathematical problem, named Weber problem, reinforced the decision of the method of allocating the factory. Additionally, not only the limitations of the cement production but also the importance weights of goods used in the manufacturing were taken into account in the iterative methodology in order to answer the engineering question via the mathematical problem. As a result, by optimizing the case through the iterations introduced in the paper, the location of the cement plant was set. Hence several losses such as extra travel distances and time wasting in transportation were minimized.No sponso
Revisiting several problems and algorithms in continuous location with lp norms
This paper addresses the general continuous single facility location
problems in finite dimension spaces under possibly different â„“p norms
in the demand points. We analyze the difficulty of this family of problems
and revisit convergence properties of some well-known algorithms.
The ultimate goal is to provide a common approach to solve the family
of continuous â„“p ordered median location problems in dimension d (including
of course the â„“p minisum or Fermat-Weber location problem
for any p ≥ 1). We prove that this approach has a polynomial worse
case complexity for monotone lambda weights and can be also applied
to constrained and even non-convex problems.Junta de AndalucÃaFondo Europeo de Desarrollo RegionalMinisterio de Ciencia e Innovació
Stochastic Multifacility Location Problem under Triangular Area Constraint with Euclidean Norm
The multifacility location issue is an augmentation of the single-location problem in which we might be keen on finding the location of various new facilities concerning different existing locations. In the present study, multifacility location under triangular zone limitation with probabilistic methodology for the weights considered in the objective function and the Euclidean distances between the locations has been presented. Scientific detailing and the explanatory arrangement have been acquired by utilizing Kuhn-Tucker conditions. The arrangement strategy has been represented with the assistance of a numerical illustration. Two sub-instances of the issue in each of which the new locations are to be situated in semi-open rectangular zone have likewise been talked about
