Support in multi-criteria decision-making under uncertainty in a transport company

The problem of finding an appropriate transportation plan for a transport company collaborating with a window manufacturer to reduce transport costs by minimizing the total distance travelled and to provide a minimum car fleet has been presented. The problem involves 3 major manufacturing bases and 15 local storehouses located in all the remaining Polish provincial capitals. Taking into account the fact that some of the parameters of the model may not be accurate due to uncertainty, fuzzy coefficients are used. Using this fuzzy model, optimistic, semi-pessimistic and pessimistic approaches are considered.
