    摘要:

    以生產(chǎn)物流系統(tǒng)為研究對象，以Petri網(wǎng)為主要工具，提出了面向對象著色賦時Petri網(wǎng)(OCTPN)的建模方法。在以基本Petri網(wǎng)對生產(chǎn)物流各子系統(tǒng)建模的基礎上，對制造加工與生產(chǎn)物流系統(tǒng)進行集成建模，建立了包括制造工藝模型和生產(chǎn)物流系統(tǒng)模型的層次化模型。最后，以汽車后橋車間的制造加工與生產(chǎn)物流系統(tǒng)為實例，建立了OCTPN模型，利用Petri網(wǎng)的活性、可達性等屬性來分析該物流系統(tǒng)的現(xiàn)狀，并用WITNESS軟件對該模型進行仿真。結果表明該系統(tǒng)是活性的，不存在自鎖, 提高了機器利用率，達到了預期效果。

    Abstract:

    Adopting the basic Petri net, the sub-systems models of the manufacturing logistics system were established. The logistics system modeling method with O-O colored timed Petri net (OCTPN) was put forward. This model method did not only have the figure and symbol description mode which was coincident with human thinking mode, but also avoided the model complexity that caused by the system complexity. At the same time, the manufacturing and logistics system has been modeled, the hierarchy model including the manufacturing process model and the logistics system model was established. Took a logistics planning in the automobile rear bridge plant as the example, the system has been modeled and analyzed with OCTPN method. WITNESS has been used in computer-aided model and simulation to design and optimize the production logistics system in the H1 automobile rear bridge plant.
