Problems solved by technology
In the process of using color petri nets, the use of arc expressions has certain limitations and cumbersomeness. The built model cannot be used universally for the order requirements in every case. Every time modeling needs to change the specific content of the arc expressions. If guard functions are added to the network, more different types of color sets need to be defined, and the logical layering is slightly complicated

Embodiment Construction
[0182] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0183] 1. Basic knowledge
[0184] 1.1 Delivery system
[0185] With the continuous development of information technology, people's lifestyles are also changing accordingly. The accelerated pace of life makes the distribution system emerge as the times require. The distribution of goods is a more convenient, efficient, energy-saving and time-saving way.
[0186] Distribution is the terminal link of commodity circulation, and distribution system is the infrastructure and organizer for commodity distribution. Many powerful production companies and third-party logistics companies have established distribution systems according to their own characteristics to carry out distribution operations for their own products or commodities they operate. Therefore, the distribution system plays a decisive role in the development of enterprises.

The invention discloses a process analysis method based on a type petri net, which belongs to the field of process analysis of a type petri net, and specifically comprises the following steps: proposing a type petri net theory; defining a type storehouse in the net, and defining a classification function on a transition output arc , to classify tokens; define transition functions on transitions to solve the problem of different types of input places and output places of transitions; add constant enabling expressions and counting functions on transitions to define transition triggering rules; jointly define Time function and manpower function are used to solve practical problems. Analyze the two schemes of the distribution system, use the type petri net theory to establish the distribution system model, give the time and manpower parameter table according to the actual situation, analyze the state transition of the two distribution schemes and construct the process transition diagram, use the type petri net theory to analyze Time resource consumption and human resource consumption under different distribution schemes to find a better solution.
Description
technical field [0001] The invention belongs to the field of process analysis of type petri nets, and in particular relates to a process analysis method based on type petri nets. Background technique [0002] Petri nets are a model for describing distributed systems. It can not only describe the structure of the system, but also simulate the operation of the system. The part describing the system structure is called the net (net), and the part describing the system state is expressed through identification. Compared with other net system models, one of the outstanding advantages of petri net is that it is easier to describe concurrency and conflict. As petri nets are widely used in various systems and processes, petri nets are extended. Currently, several advanced petri nets are more mature, including color petri nets, time petri nets, logical petri nets and so on. [0003] The essence of the color petri net is to classify the tokens to realize the folding of the net. Co...
