网络协同设计过程的任务分解算法模型研究

云制造通常需要云端资源协作完成一项任务,为了进行云制造任务的分解,以实现合理的资源匹配,文中首先充分考虑了云环境下的任务属性,研究了基于物元模型的任务表达方法;其次,对传统的顺序任务分解方法(OTD)进行改进,来修正不可行解来获得可行解,增加了解的多样性,避免了分解失败重新启动分解程序而消耗的时间和精力;最后,以固定卷...

Research on task decomposition algorithm model in network collaborative design process

Cloud manufacturing is a task that usually needs to cooperate in cloud resources.In order to decompose cloud manufacturing tasks and reasonably match resources,firstly,the task attributes in cloud environment were fully considered,and expression methods based on matter-element model were studied;secondly,the traditional ordered task decomposition(OTD)was improved,and infeasible solutions were corrected to obtain feasible solutions,so as to increase the diversity of solutions and avoid the waste of time and energy caused by restarting the decomposition program due to failure;finally,taking the manufacturing task of fixed hoist in cloud environment as an example,the research method was verified.
