Assigning priorities in technological hubs using simulation and fuzzy logic
The tasks of priorities assignment to applications, work, actions and simply objects of activity are
decided long ago and in different ways. In purely technical systems, including computer and communication
systems, where serving processes can be programmed explicitly, such tasks are considered to
be practically solved, because: first, two counterprocesses are analyzed (the service process and the
waiting process), If the serving node is busy, and secondly, the time parameters are taked into account
mainly. In this case, as a rule, the waiting time for some classes of applications is minimized. However,
in schemes of multi-nomenclature productions, especially high technology products, the efficiency
of production or the production site depends not only on the direct losses of time, since delays can be
evaluated in a different way, taking into account the funding resources, urgency resources and even the
administrative resource. Therefore, clear rules and algorithms can become fuzzy, and the task of minimizing
losses is complicated. This article is devoted to the joint application of simulation modeling and
fuzzy logic algorithms in the tasks of priorities operational assignment for application in technological
hubs. Particular attention is paid to the development of a unified program function for fuzzy priorities
assignment in models created through the licensed software package Actor Pilgrim. The information
links of this program function with the internal atomic data structures of simulation model are also
considered. The considered models are intended for use in two-scale adaptive fuzzy control systems.
