The article discusses the main problems and features of test planning of serviceability of flexible production systems (FPS) equipment, taking into account all possible factors. The basic dependencies of repair and verification at variable operating modes have been monitored and possibl1e ranges of system existence depending on internal factors and changes in working time, environmental characteristics and factors affected the system have been derived. As the result of the analysis, mathematical modeling and determination of critical conditions of existence of the system have been carried out. The basic criteria and tolerances for the normal operation of FPS equipment have been determined. The calculated dependencies for the further improvement of the system and the parameters for the smooth operation of the equipment by means of a mathematical analysis have been found. Methods of test planning of operability of FPS equipment have been developed, the time frame of stopping various systems for the slightest l ss of production capacity, taking into account the duration of the diagnostic work of used equipment has been determined. The planning of inspections for a product that is in a state of readiness for action, possible only after replacement, is considered. These circumstances allow us to determine the optimal interval between inspections by the criterion of minimum expected costs, attributed to the average time of serviceability for the cycle in steady state. When planning inspections of a product that is in a state of static readiness for action, the possibility of making erroneous decisions during the inspection is taken into account. The products which start to act at occurrence of some emergency conditions which moments of occurrence are casual and have distribution W (t) are considered. It is determined that inspections and necessary repairs allow to increase readiness, if at the same time certain conditions concerning quantitative ratios of the sizes influencing it are fulfilled.
