Network Model for Planning Internal Movements in the Hajj

摘要

The purpose of this paper is to identify issues in the Hajj internal transportation network and model the situation in order to draw general policy decisions in management of this unique situation. The most important constraints in this case are the religious ones, actually they define the transportation and the movement of the people from one place to another. Any model must reflect these constraints in order to be implementable. These religious constraints are represented as time and space constraints. A temporal capacitated network is developed to represent the situation, with the objective to minimize congestion of traffic on roads and overcrowding of the holy places. This objective is chosen to enable the visitors to perform their duties as easily as possible. In section 2 the authors describe the Hajj situation briefly, and in section 3 identify issues to be considered in the modeling process. In section 4 they develop the model, and in section 5 present a numerical example and the conclusion of this paper.
