The problem of allocation of solid municipal waste (SMW) disposal objects is extremely acute for Russia. The complexity of such tasks is primarily due to their interdisciplinarity, i.e., a significant amount of social, economic and technical data and environmental information to be taken into account. In many countries, multi-criteria methods have been used for this purpose, which have proved their effectiveness, making it possible to work out a compromise and objective solution. The methods of T.L. Saaty - analysis of hierarchies (AHP) - and analysis of networks (ANP) are considered, as well as the examples of their use for choosing sites for landfills and waste incinerator plants.
