Conceptual structure of the logistic process simulation model of repairs management at the power network enterprise

The articlefocuses on the problem of simulating repairs processes to minimize expenses of power network enterprises on inner logistic processes. There have been detected special features of logistic processes of maintenance and repair of assets of power network enterprises. It has been stated that efficiency of management of maintenance and repair processes of assets can be determined by the ratio of their structure-making elements and special features linked to territorial isolation, a great number of repair goods, multilayer management, factors of randomness in realization of repair program. Computer support of management decision making of the logistic processes in the repairs area of the power network is based on simulating structural elements of maintenance and repair processes. The choice of methods is stipulated by the continuously-stochastic way of the process running. There has been developed and submitted the structure chart of technological processes of repairs management of the power network area in Q-charts symbolics, generalized and detailed charts of a simulating algorithm, described their principal of operation. There has been built the graph of interrelation of elements forming the process of repairs management in a power network enterprise. Elements making a stochastic process of interrelation of repair management elements have been detailed, according to quantities of their statuses. Submodel "Consumption of consumed material and technical resources" realized in Arena simulating package has been described in details. The conceptual structure of a simulation model of logistic processes of maintenance and repair of assets of power network enterprise including the description of classes (transacts, resources) and processes, attributes and charts of variable conditions have been provided.
