Abstract
Modern conditions of functioning of enterprises within the framework of a market economy, as well as in the conditions of uncertainty and instability of the external environment, require new, highly effective means and methods of managing their economic activity. In this paper, the partial problem of modeling the work of a flexible production-logistic system (FPLS) with the use of a class of models based on the basis of mass management systems (MMS) is considered, which allows one to obtain a sufficiently large number of characteristics that are used in finding the optimal parameters of FPLS, is considered. This problem is modeling of work of the enterprise warehouse using model of mass service system with threshold inclusion and limited resources. The paper noted that an important disadvantage of modern approaches to the organization of production is the fact that all technological systems are regarded as ideal systems, that is, they are deterministic. Observation of real objects that we associate with complex systems demonstrates that they function in conditions of a large number of random factors, so predicting its behavior can only be meaningful within the probabilistic categories. The represented graph of states of the system with threshold inclusion allows one to perform the orientation of the device (a steady stream of intensity requirements λ). It is shown that the material flow can be classified according to the degree of variability. This principle distinguishes between stationary and non-stationary flows, as well as ordinary and extraordinary streams. The service algorithm is allocated. In this work, it is assumed that the execution of the order for the manufacture of one or another type of products is in the order of receipt. A generalized model of formation of stocks is obtained, which links the «enterprise – warehouse» logistics chain and represents a functional cost. It is confirmed that the use of tools of industrial logistics combined with the ideology of modeling of logistic models of the warehouse with the definition of its optimal, in terms of enterprise, parameters, in particular, the model of warehouse management with a deficit. It is suggested to use a class of models for modeling the work of warehouses of the enterprise, which are based on the basis of managed mass service systems and allow one to obtain a sufficiently large number of characteristics used in finding optimal parameters of flexible production and logistic systems (FPLG), which are able to react quickly to market conditions.
