Applying Multi-Criteria Decision Aiding techniques in the process of project management within the wedding planning business

Numerous problems that emerge in the process of project management can be presented as multi-criteria issues and solved with the help of the appropriate methods. The contracting authority, selecting one tender out of many available tenders, assesses them, taking into account various criteria, e.g. price, expected execution time and the contractor’s experience. The owner of the company intending to purchase fixed assets requisite for the realization of the project behaves similarly, i.e. the most advantageous model of the device is chosen taking into account not only its price but also production capacity, energy intensity, noise emission, service availability, etc. The investor among many project concepts has to choose the solution which constitutes frequently a compromise between price, usable properties, durability and aesthetics of performance as well as safety of the utilization and impact on the environment. The choice of the investment location depends not only on the market, financial and supply factors but also on the so called soft factors such as perceived quality of institutions and local communities’ attitude. All of these situations can be described in the same way: the best possible choice must be made out of a finite set of decision-making variants evaluated against a finite set of criteria. There are many different methods that can be used to aid decision-maker in this choice, i.a. techniques based on the outranking relation, verbal decision analysis and MACBETH method. In the article they will be compared and the possibilities of their application in different types of decision-making problems will be pointed out. As an illustrating example the case of selecting the best technology of flood levee insulating will be presented.
