The assessment of efficiency of a cybernetical and economical system of “transport–resources”

In the paper the assessment of efficiency of cybernetical and economical systems of “transport – resources” type with the failure transportation system has been presented. The system consists of single sender of resources and single receiver as well as the store of resources as a buffer enabling the receiver to work continuously even in the standby situation of the lack of resources from the receiver. The so-called function of loss is the measure of efficiency of the systems (in economical aspect). The function deals with a total loss of the system connected with costs of taking over resources from the sender, costs of storing the resources and costs of standby resources from external contractors (in case of deficit). In the function of loss the additional profits of the system have been taken into account which result from the sales of excess of the resources in the store (in the situation of excess) to the external contractors. Based on of the detailed analysis of the function of loss for different variants of system operating it was possible to draw very useful and practical conclusions which enable such a functioning of the system (through the proper choice of its parameters that) it could operate most effectively (suffer a relatively low loss).
