基于TCPN复杂产品设计任务资源调度及应用研究

针对复杂产品设计任务模块资源调度冲突问题,在分析TCPN网中资源约束下基本结构的设计任务元活动变迁的输入与输出资源库所数量的基础上,构建基于TCPN网设计任务模块的资源约束TCPN模型,围绕资源约束TCPN网中同步活动任务变迁与非同步活动任务变迁,给出不同的资源约束调度规则,并设计完整的资源约束调度算法与修正算法,研究给出可调度的设计任务模块资源约束TCPN网.最后,以J企业某型号汽车研发项目为例,构建汽车底盘设计模块设计任务元的资源约束TCPN模型并进行求解,给出汽车底盘设计任务模块的可调度资源配置,实现汽车底盘协同研发资源约束TCPN网中的所有设计任务元活动变迁皆可调度.

Research on resource scheduling and application of complex product design based on timing constraint petri nets

For the problem of resource scheduling conflict of complex product design task modules, this study constructs a resource-constrained TCPN model based on TCPN network design task module with the analysis of the number of input and output repository design mission activities under the basic structure of the TCPN network resource constraints on change. Concerning the resource constrained TCPN network synchronization task transition and non-synchronous activity task transition, given different resource constrained scheduling rules, and design a complete resource constrained scheduling algorithm and correction algorithm, this paper presents a schedulable design task module resource constraint TCPN network. Finally, take a J-model car R&D project as an example, resource constraint TCPN model of vehicle chassis design module design task element is built and solved, the schedulable resource configuration of vehicle chassis design tasks module is given, and the meta activity changes of all design tasks in the automotive chassis collaborative R&D resource constraints TCPN network can be scheduled.
