ROUTE MAPS PLANNING PRIORITY MODEL IN ENGINEERING

One of the most important tasks in our country is the further development of the economy of industrial production, including increasing the depth of redistribution of domestic industrial products, predetermining the need for automation and computerization of machine-building production, the creation of modern methods of the digital economy in terms of optimizing the supply curve. This leads to the formulation of the tasks of improving the planning and management system of engineering production. Machine-building enterprises need a capacity planning system that would objectively reflect the established economic situation in order to make appropriate management decisions. The main objective of planning is the formation of a production schedule, the maximum load of work centers, taking into account the existing restrictions and priorities of orders. The paper shows enlarged or inter-workshop planning of a production schedule for a long planning horizon and detailed or operational intra-workshop planning, taking into account the production schedule, the availability of work centers and production facilities. A comparison of the planning levels. At the stage of enlarged planning, a production schedule is planned, which is a calendar schedule for the execution of production routing maps and allows to evaluate the feasibility of received orders for production by the date of need, to reschedule the constructed schedule when changes and deviations are made in production plans. At this stage, during the initial placement of the order in the production schedule for each line, the possibility of fulfilling the order by the specified requirement date is determined. If it is impossible to ensure the production of a particular product by the date of need, the date of its intended release is calculated. The production schedule is transferred to the level of detailed planning - the volume of work per planning interval, for the execution of which the availability of groups of work centers is enough for a given interval. Within this interval, a specific execution time is planned for each operation with the definition of specific work centers that will be involved in the execution of operations. As a result of mathematical calculations, the recommended sequence of planning production route maps is obtained. The mathematical model presented in the work of choosing the priority for planning routing maps of production allows us to calculate the feasibility of orders on time, and also to determine the planned time interval in which each routing map should be completed.
