The techniques of simulating modelling in the AnyLogic program environment are considered. The object of the study is the production task of a machine tool with computer numerical control (CNC) in pilot batch production (PBP), characterized by a variety of products and a small batch size. To build a digital work model, a variant with parallel chains of events is chosen, reflecting the technological processes of manufacturing each part and the equipment changeover. The paper considers the tools allowing one to encode the existing blocks of the program tool palette under the logic of the described equipment operation. Based on the work results, a simulation model of the computer numerical control machine is created and described, which makes it possible to conduct optimization experiments to check the quality of the made managerial decisions. The aim of the study is to optimize a shift task in pilot batch production using the simulation model. The objective of the study is to create a correct simulation model of the computer numerical control machine in the AnyLogic software environment. The research methods of simulation modelling are used. The novelty of the work lies in creating a simulation model of operating a computer numerical control machine, taking into account the changeovers. The result of the study is the built digital model of the equipment operation, which allows optimizing a shift task according to the required criteria. The findings of the study state that the resulting simulation model reflects the technological processes of manufacturing parts, limitations in the operating mode and equipment changeover processes, which makes it possible to conduct optimization experiments to increase equipment productivity. |
