In the thesis we present Petri nets as a way of describing workflow processes. We present the structure of Petri nets and describe the way of transitioning between different states of a Petri net. We present the nets on a few simple examples.
In the following, we consider the process of purchasing network equipment, which uses the Build and Price service from Cisco Systems as information support. The process is relatively time consuming if used manually, especially if the process enables multiple corrections and editing of offers, which can be the result of direct negotiations on one hand, and the result of manually entered errors on the other. We describe the whole process using Petri nets and approach its automation and optimization.
The optimization of the process is carried out with a software solution, which in the first phase automates the utilization of the Build and Price service, designed for systematic vendor bid preparation. In the second phase, it efficiently compiles data on desired procurement items for the company's clients within the scope of the proposal. We also provide a rough assessment of the time savings achieved and suggest some further improvements.
