Dimensioning of Multiple Capacity Transport Line with Mutual Traffic Correlation

Transport networks need very effective optimization tool for good utilization of transport line capacities. Planning and dimensioning of capacities can be done in definite planning horizon or to satisfy offered traffic from point to point, crossing multiple lines on the path. Such approach is the crucial part of every Intelligent Transport System (ITS) today. Capacity dimensioning is an important element of resource management and it can be seen as CEP (Capacity Expansion Problem). In the case of CEP for multiple line capacities of transport line with mutual traffic correlation such problem could be more demanding. Mathematical model for optimal capacity sizing of N different transport types (capacity types) is explained, minimizing the total expansion cost. Instead of nonlinear polynomial convex optimization technique, that could be very exhausted, the network optimization method is applied. With such approach an efficient algorithm for three different capacity types is being developed.
