【摘要】：为支持复杂产品装配作业过程的优化与控制、降低建模复杂度,提出一种基于"作业—资源流图"的装配系统分析模型快速构建方法。该方法以装配站为基本分析单元,首先依据装配作业工序与资源的相互作用,建立面向装配现场的工序作业流和资源供给流,实现作业逻辑的快速、直观表述;采用离散事件和状态的提取与表示方法,将作业逻辑模型自动转化为具有离散事件分析能力的Petri网性能分析模型,并利用作业规则设定函数实现在制品和资源配置方案的完整表述。以飞机襟副翼装配的"作业—资源流图"为基础,介绍了装配生产率、资源利用率以及资源配置方案的分析与优化过程,验证了方法的有效性。
[Abstract]:In order to support the optimization and control of the assembly process of complex products and reduce the complexity of modeling, a rapid construction method of assembly system analysis model based on "Activity-Resource flow Graph" is proposed. In this method, the assembly station is taken as the basic analysis unit. Firstly, according to the interaction between the assembly process and the resources, the process job flow and the resource supply flow are established to realize the fast and intuitionistic expression of the job logic. By using the method of extracting and representing discrete events and states, the job logic model is automatically transformed into the performance analysis model of Petri nets with discrete event analysis ability. And the job rule setting function is used to realize the complete representation of the WIP and resource allocation scheme. The analysis and optimization process of assembly productivity, resource utilization and resource allocation scheme are introduced based on the "Activity-Resource flow Graph" of aircraft flaperon assembly, and the validity of the method is verified.
