This report describes MM, a computer program that can model a variety of mechanical and fluid systems. Given a system's structure and qualitative behavior, MM searches for models using an energy-based modeling framework. MM uses general facts about physical systems to relate behavioral and model properties. These facts enable a more focussed search for models than would be obtained by mere comparison of desired and predicted behaviors. When these facts do not apply, MM uses behavior-constrained qualitative simulation to verify candidate models efficiently. MM can also design experiments to distinguish among multiple candidate models.

Цель исследования анализ и оценка экономической эффективности внедрения информационного моделирования в проектную деятельность. Научная новизна исследования состоит в проведении анализа на более позднем этапе применения информационного моделирования в проектировании. В итоге получены результаты оценки экономической эффективности, позволяющие проецировать и давать укрупненный прогноз роста затрат и доходов организаций, планирующих внедрить информационное моделирование в свою проектную деятельность. / The purpose of the study is to analyze and evaluate the economic efficiency of introducing information modeling into project activities. The scientific novelty of the study lies in the analysis at a later stage of the application of information modeling in design. As a result, the results of the economic efficiency assessment were obtained, which allow projecting and giving an enlarged forecast of the growth of costs and incomes of organizations planning to introduce information modeling into their project activities.
