The modification of the amount of operational potential during the exploitation phase of a complex technical object

An operational potential is the measure of a usability of a technical object. The operating and service processes carried out during an exploitation phase change the quantity of the operational potential enclosed in the object. The operating processes decrease and the service processes increase this potential. Therefore, during the exploitation phase, the usability of the machine changes. Describing a process of changes in the operational potential as a time function, it is possible to determine a moment of time at which the operation process should be stopped and the service process should be started to avoid disability of the object. This issue is especially important in the case of a complex, crucial, technical object, because, for such an object, the moment to start the service process has to be determined several months in advance. In the paper, a function of the amount of the operational potential enclosed in the object is described. Next, the
