Для ефективного застосування фізичних аналогій при оптимізації непередбачених ресурсних потоків у проектному середовищі, які виникають, наприклад, при компенсації ризикових подій, необхідна наявність адекватної дискретної адаптивної віртуальної моделі простору управління проектами. Запропоновано метод побудови "гарячої" моделі на основі попередньої віртуальної передислокації її елементів в усіх функціональних областях. Модель практично реалізована при будівництві енергоспоруджень з позитивним технічним ефектом.
For the effective use of physical analogies in the optimization ofemergency resource in the environment of design flows that occur, for example, when payment risk events, you need adequate adaptive virtual space discrete models ofproject management. The proposed method of constructing "hot" based on the model of the previous virtual relocation of its members in all functional areas. The model is practically implemented in the construction energoprojekt with a positive technical effect. Any thermodynamic substance (heat, pressure, weight, etc.), cannot abruptly go through any small area carrying, she must go all the way through all of the elements between the beginning and the end of the transfer without tearing and logistics resource can also move in that sense continuously, and may "jump" to any distance from the project start element to the end, bypassing all the intermediate elements. For playback of such "jumps" in the model a method is proposed, which involves preliminary "hot" relocation of a discrete space-time of the project activities. Under hot-relocation will understand prior changes in the structure of the original ordered discrete space-time, which runs continuously during the execution of the project, regardless ofwhether there are some risk events or not. That is, the current model structure of a discrete space-time is constantly changing, reproducing the current state of the existing cell and storage resources. The developed method of on-line geometrical adaptation of the structure of the elements of the environment to the real needs of the optimization processes, with the Express design of logistics flows, aimed at minimizing losses during the realization of risk events. Tests in Corporation "UNION" showed: the project execution period is reduced by 11 %; the cost of implementation of the project was reduced to 1,25 %; the amount of risk, which managed to be prevented – 17 %.
