产品协同设计中的任务调度方法研究

Research on Task Scheduling Method for Product Cooperative Design

分析并行工程下协同设计的特点，提出一种事件触发的任务调度策略。为了合理地进行任务调度，在提出调度获益函数的基础上建立了协同设计的任务调度模型。运用遗传算法求解该调度模型。结果显示了该调度算法的有效性，从而为产品的协同设计任务调度提供了一种有效的方法。

Cooperative Design carried out by multidisciplinary specialists is emphasized in Concurrent Engineering. In order to accelerate the whole design pr0cess,task executing pr0cess shou1d be scheduled rationa1ly.Because of the uncertainty of the design process and diversity of affecting factors, the scheduling method shouldbe f1exible. In this paper, the characteristics of cooperative design are analyzed and an event - driving taskscheduling strategy is proposed. Based on the pr0fit function of schedule proposed a scheduling model is set up.To solve this scheduling prob1em which is NP-Completeprob1em,a genetic alg0rithm is used and the result of aexample shows it'svalidity. Thus this paper offers a effective task scheduling method for product cooperativedesign .
