Abstract:

In this article we will develop a mathematical model for a cost‐efficient selection of vehicles with varying capacities for line haul transports with leasing options. For this integer optimization problem, which is a variant of the generalized assignment problem known as NP‐hard, we will compare two heuristic solution concepts and try to answer the question in which cases a user should choose an exact or approximate solution concept depending on different data instances of the problem.
