The location set covering problem (lscp) was defined more than thirty years ago by toregas this second type of covering problem is called the maximal covering location problem the reductions process has been applied to a set of four different problem data sets. The maximal covering location problem was first introduced by church and revelle in 1973 at the north american regional science council meetings and subsequently published in papers in regional science (formerly papers of the regional science association) in 1974. Icie (2016) all the vehicles stationed in that facility salari [13] proposed a generalization of the maximal covering location problem, in which facilities may follow different scenarios and. Maximal covering location problem with price decision for revenue maximization 559 for different values of p, we reveal a finite domination property with respect to price of the deduced revenue maximization model, leading to a full enumeration solution.

The maximal covering location problem (mclp) is the problem of locating p facilities on a network such that the maximal population is attended (or covered) within a. This study introduces the multi-type maximal covering location problem (mtmclp) that arises from the design of emergency service networks, and represents a generalization of the well-known maximal covering for determining optimal location of medical centers of different types (ambulances, heath-care centers, clinics, etc) in addition, the. The maximal covering location problem (mcp) is a mathematical problem used in deciding the location of emergency facilities such as fire stations and oil spill response centers [2,4, 1 i. This study introduces a new model for the planar maximal covering location problem (pmclp) under different block norms the problem involves locating p facilities anywhere on the plane in order to cover the maximum number of n given demand points. The maximal covering location problem (mclp) model and the large number of applications and modifications that have emanated from it have been extensively used to site facility networks in a wide variety of applications in this article, we formulate and apply an extension of mclp, the maximal.

Problem has been extended in a number of different ways where the main theme still involves locating a fixed number of facilities maximal covering location problem (mclp) (church and revelle 1974) in the mclp, a fixed number of facilities are located so as to provide coverage to the largest number of users. To improve the application of the maximal covering location problem (mclp), several capacitated mclp models were proposed to consider the capacity limits of facilities. To this end and with regard to covering problem applications, this problem is inclusively studied in the operations research (or) literature this article proposes a novel maximal covering location problem (mclp) in which different factors (capacity of facilities, budget, number of available facilities in different types) have been considered.

  • In this study, we formulate the ambulance location problem as a deterministic multi-level maximal coverage model by which the total demand is tried to be covered as many as possible at multiple levels.
  • Coverage location problem a transportation network is given together with the locations of customers and facilities covering all the vertices), the existence of a polynomial-time algorithm for our problem we say that us is maximal if us # 0 and ut = 0 for every t 2s.

Location problem (mclp) and set covering location problem (sclp) in covering problems, a demand is said to be covered if at least one facility is located within a predefined distance of it. The maximal covering location problem (mclp) aims to select the location of a fixed number of facilities to maximize covered nodes a covered node has at least one facility within a predetermined distance or time, called the ‘covering radius. The p-hub maximal covering problem maximizes the demands that are covered with a predetermined number of hubs the problem for both allocations is posed by campbell [6. The maximal covering location problem (mclp) is a challenging problem with numerous applications in practice previous publications in the area of mclp proposed models and presented solution methodologies to solve this problem with up to 900 nodes.
