Abstract

The invention provides an integrated production task scheduling method for task reliability. The method comprises the specific steps that 1, based on a manufacturing system, a production task and an internal relation of a manufactured product, determining a key machine and a key process influencing task reliability are determined; 2, determining the performance state of each machine; 3, quantifying a product quality deviation index; 4, establishing a QPPN model according to task requirements; 5, giving a heuristic rule based on task reliability; 6, searching a production task scheduling optimal solution; and 7, analyzing the result, and comparing the result obtained by the production scheduling method with the result of the production scheduling method which does not consider the task reliability. According to the method, the influence of production task scheduling on the quality of the manufactured workpiece is fully considered, the defect that production scheduling and product quality detection are independently considered in the traditional manufacturing process is fundamentally overcome, the task reliability of a manufacturing system is improved, and the method has very good practical value.

Description

technical field [0001] The invention provides a task reliability-oriented integrated production task scheduling method, which belongs to the field of production management. Background technique [0002] The manufacturing industry is the economic lifeline of a country. Strong manufacturing support is the prerequisite for the country's stable development, and advanced manufacturing technology is undoubtedly the core competitiveness of the manufacturing industry. With the increasingly complex functions and structures of the manufacturing system and the intensified changes in market demand, in an intelligent environment, the production scheduling method optimized at the manufacturing system level is becoming more and more important in production. It can not only ensure the complex production environment The on-time completion of the next production task has a key impact on the quality of the produced product and the performance of the manufacturing system itself. Therefore, the...
