Five characteristics of production scheduling environment help to understand the application environment of scheduling algorithm

The general scheduling problem is an abstraction and simplification of complex, dynamic and multi-objective scheduling problems in a specific production environment, so a scheduling algorithm can classify them by how to express these complexities. Since the actual production environment is very different, a scheduling algorithm should be evaluated according to its suitability for the important characteristics of the corresponding production environment. To help distinguish different production scheduling strategies, five characteristics of typical production scheduling environment are given, which will help people to understand the application environment of various scheduling algorithms. &http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; 1, the boundary conditions production scheduling is often a rescheduling problem, that is, modify the existing production scheduling to adapt to the new job. In order to provide rescheduling, the scheduling algorithm should be able to deal with the initial state in the production system.   Similar production scheduling is usually carried out in a finite time zone, and the optimal solution or suboptimal solution of the system is also obtained within the bounded bounds.   2. Batch size and adjustment cost to effectively solve the scheduling problem in the actual production, the task is often divided into batches, and the cost of changing the existing scheduling structure is considered.   3, processing path in the actual production, the operation of the processing path may need dynamic change, the process sequence may be half ordered.   4, random events and perturbation random events and disturbances include the emergence of key operations, equipment damage, processing operations failure, raw material shortages, processing time/arrival time/delivery date changes.   5, performance Index and multi-objective pursuit of different performance indicators will often get different optimization solution, at the same time, the system goals are mainly multiple targets.
