Abstract

The article analyzes the instability causes of construction and assembly works (CAW) schedules which leads to the construction works and logistics instability. The “nature” of multi-variant management solutions is considered. The contradiction of requirements to the basic organizational and technological model (OTM) to solve scheduling problems of CAW and construction works is revealed. The basic “an object construction technology model” as “an object techno-logical dependencies models” is considered. A new approach is proposed to solve the problem of CAW scheduling, which includes two-step managerial decisions development at the CAW planning stage and construction works organization stage. At the first stage, the problem is reduced to finding a solution (and not to determining an optimal variant). At the second stage, the problem is solved through optimization.
