Abstract
The article deals with the modeling of logistic processes of construction with the help of probability theory. Random deviations accompany any natural process, and even more so logistic processes in construction. Practice sets such tasks in which various factors play a significant role in the processes under consideration, but the number of these factors is so large that it is not always possible to trace cause-and-effect relationships between them. Elements of uncertainty, complexity, multiple causes inherent in random phenomena and processes in logistics, and therefore require special methods for their investigation, study and management. Such methods are developed by probability theory.
