The Estimation of the Operational Capacity of the Logistic System According to the Level of the Functionality Status of its Constituent Organizations

The operational capacity represents one of the most important characteristics of the logistic system, from the perspective of its reliability. The present paper describes, concisely, in its first part, the theoretic foundations of the analysis and of the evaluation of a logistic system from the point of view of the reliability function and in its second part there are introduced two models of a system which consists of n components, which is operational in the circumstances in which at least k components, out of the n components, are operational. In the two models it’s analyzed the functionality of the logistic system, at its two levels –the upstream level and the downstream level-, from the point of view of the level of the operational status of the suppliers, respectively of the distribution centers. In this context, it results that a special influence is exerted by the number of the logistics centers, as key elements of the logistic system. Finally, it’s carried out an evaluation of the way in which the operational capacity of the introduced logistic system is determined by the functionality statuses of the organizations from which the system is composed.
