Construction equipment has a great impact on the overall cost of
construction projects. Therefore, careful planning and selection of
appropriate combination of equipment is essential for the economic
success of the contractor. In practice, the process of equipment selection is
mainly based on manufacturer’s recommendations and the contractor’s
intuition without using any scientifically based method.
This paper discusses a model for selection of an optimal set of construction
machines by applying the multi criterion AHP method. The model is based
on comparison of alternative sets using the selected criteria functions
which are defined by the user at the start of each optimization. The
proposed method has been successfully tested on a case of construction of
embankment on a highway section on Corridor X in Serbia. The criteria
functions were: output, unit price and profit per unit. A sensitivity analysis
was also performed to check the stability of the final decision.
