METHODS FOR MARSHALING YARD LOCATION PROBLEM
Keywords:
distribution system, heuristic, many-to-many, exact method, marshaling yardAbstract
A cargo railway system is a transportation system, which has approximately the same number of primary sources as number of customers. Flows of carriages from primary sources to customers are concentrated in terminals (marshaling yards) to create a bigger flow between them. This model is called „many-to many“ distribution system, belongs to discrete quadratic programmes and the optimal solution can’t be founded because of time purposes. For estimating the optimal value can be used the lower bound solution of the model. Estimation of optimal value can be used for comparision of “quality” of solutions obtained by aproximative and heuristics methods.
