Vehicles Distribution and Lines Planning in Public Transportation A case Study: Wad Medani, Gezira State, Sudan

摘要

Transportation model is popular taxonomy of optimization problems, which concerns with goods distribution from different locations as supply to multiple destinations as demands. This paper proposes a solution for public transportation in Wedmedani city. The solution consists of two parts; the first, is the model that distributes available vehicles according to neighbourhood demands; the second part proposes a new lines planning that minimizes the overall distance and avoids the problem with existing lines plan that follows the star topology. We used Vogel Approximation Method (VAM) to generate initial basic feasible solution then we used this solution as an input for modified distribution method to check its optimality and produced better distribution as a solution. The results show that VAM has ability to find optimal solution in a given dataset according the optimality check achieved by MODI. Clarke and Wright method has been used to generate the lines planning and the obtained results show that the new planning has reduced the total distance by 50 percent.
