DEVELOPMENT OF A METHODOLOGY FOR DESIGNING A SIMULATION MODEL OF A GRAIN COLLECTION AND TRANSPORTATION COMPLEX

The relevance of the topic of the work is determined by the fact that the use of simulation modeling allows you to assess the efficiency of the collection and transport complex, identify its bottlenecks, reduce costs and increase productivity [1]. In agricultural production, the most widespread are systems of mass service with waiting. These are systems in which the request received at a given time (all service channels are busy) is queued and waits until the channel is free. Thus, a combine with a full hopper does not leave the system and waits for the next vehicle to unload grain. If a request received in the system (stopping a combine with a full hopper), finds all the vehicles busy loading other combines, it is forced to wait its turn until one of the vehicles is free. After servicing (unloading the hopper), the combines are again serviced after some time.
