Operational Management of Long-cycle Production Parts Based on the AnyLogic Simulation Model

The article examines the construction of a simulation model for a portion of a machining production area operating in a pilot production environment, where batch production is combined with the processing of one-off pilot parts. The simulation model was built using AnyLogic software. Three types of parts were selected as agents: two batch parts with long production cycles (over a month) and experimental design work, conventionally combined into a single "pilot parts" agent. The model architecture utilized a cyclical approach to reflect the manufacturing processes of batch parts with long production cyclesmore accurately. The use of a cyclical approach, as opposed to a linear one, allows for the parts returned for the machining, for example, in the "machining - heat treatment - machining" cycle to be taken into account. The model includes blocks for creating processing queues in front of each piece of equipment. A queue is created when the processing intensity, the batch being launched, and interruptions in the processing of batch parts during the rapid launch of pilot parts desynchronize. Primary information on the receipt of workpieces, their arrival time, and quantities is entered using an Excel spreadsheet. Modifying the primary data in the spreadsheet allows for the simulation of various production situations. The process of model construction, data preparation, and potential production process indicators for management decision-making are described. A comparison of cyclical and linear approaches for constructing simulation models is presented, demonstrating the advantage of the cyclical approach for parts with long cycle times and repetitive processing. The proposed model allows for the simulation of the process of launching parts into processing, taking into account the required criteria: equipment load or production cycle duration.
