Decision making with use of AHP method in construction
Languages of publication
One of the most difficult problems in construction having to take an objective decision, especially when selecting contractors. The decision making process is both complicated and time consuming (due to the complex nature of construction projects). Many experts, with extensive knowledge of the Construction Industry, take subjective decisions, related to verbal methods of decision making. The previously mentioned difficulties mainly relate to the creation of a relevant criteria set, answering the decision makers questions. A proper criteria set and mathematical tools (like computer calculation algorithms with multi-criteria analysis) could significantly improve objective decision making. The authors present a case study – selection of contractors – with detailed calculations of AHP method.
