Operational rescheduling of production plans using technologies and algorithms of flexible production systems
The application of technologies of flexible production systems is proposed to make a decide of drawing up of production plans for complex structured systems. The electric steelmaking is considered as an example. The steel processing schemes are described taking into account the available aggregates of various groups and types. The ways to produce some steel grades using alternative technological routes are found. This allows one to consider several variants of the original production schedule and ways of its rescheduling in the course of production process. Possible processing schemes of steelmaking production are described, and aggregates of various groups and types are presented. There is a dependence between the processing schemes and the resulting steel grade, which significantly complicates the process of making and adjusting the schedule. The authors substantiate the need for the application of flexible production systems technologies under the conditions of a metallurgical enterprise. The main stages are determined and an algorithm for synthesizing of possible options for operational rescheduling is developed. It depends on the current organizational and technological situation.
