| Tiivistelmä: | In this paper the authors elaborate on a mathematical programming model that selects suppliers of a multiple item service and simultaneously determines market shares of the suppliers selected. The methodology is based on the collection of total cost of ownership (TCO) information, quantifying all the costs associated with the purchasing process throughout the entire value chain of the firm. In this paper, the authors have modelled the real-life problem of purchasing business air travel within Alcatel Bell. To the best of the authors knowledge, their approach is the first model that makes TCO concept operational in a service-purchasing context. |
