Route maps planning priority model in engineering

Economic & mathematical methods and models

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. It predetermines the need for automation and computerization of machine-building production, introduction of modern methods of the digital economy in terms of optimizing the supply curve. This leads to setting 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 for efficient management decision-making. The main planning objective is to form a production schedule, 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 We take the production schedule, the availability of work centers and production facilities into account. The planning levels are compared. At the stage of enlarged planning, a production schedule consists in a calendar schedule for the execution of production routing maps. It allows to evaluate the feasibility of received orders for production by the date of need, to reschedule the constructed schedule when changes and deviations take place in the 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, we obtained a recommended sequence of planning production route maps. The mathematical model of choosing the planning priority for production mapping presented in the work 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.
