Modeling And Research Of Vending Machine Sales System And Logistics Distribution Based On Petri Net

Vending machine is a marketing system which contains the Merchandising and the Distribution. With the development of technology, the vending machines have more functions, for example, load wireless module in traditional vending machines, through the short messaging to monitor vending machine sales and machine status; it makes the system process more complex. To make the system developers, maintenance supplies staff and monitor staff have a unified understanding of vending machine, rational organization and optimize the internal logistics and distribution methods, then make a reasonable logistics control system, it is necessary to establish a system to simulate the dynamic operation of the model accurately, and improve quantitative analysis of effects, to achieve system performance analysis.As the vending machine system is a discrete event dynamic system, we must use a specific modeling tool. This paper introduces the theory of Petri nets. Starting from the basic Petri nets, introducing the basic principles and nature of Petri nets, then use Petri net modeling technique in the vending machine system, finally manufacture a traditional vending machine sale monitoring system and information on short sales of the system Petri net model, perform by using simulation tools. Specific to the wireless technology of vending machines logistics process reengineering issues, bring up a Petri net inhibition of the process model. This kind of model is applicable to describe the wireless information on the logistics and distribution of decision-making, comparing vending machine with the traditional logistics model, simulate the two different shortage distribution process, and analyze process performance improvements in the aspect of time.
