MODELING AND CALCULATION OF PERFORMANCE INDICATORS OF COMPUTER INFORMATION SYSTEMS

Wednesday, February 26, 2020
The efficiency of modern companies depends largely on the efficiency of computer information systems (CIS). The efficiency of the CIS can analyzed by modeling and calculating their performance indicators. For the analysis and mod- eling of the CIS of the “client-server” class, the most widely used mathematical apparatus of Petri nets and the theory of queuing. Representation of the CIS in the form of a Petri net makes it possible to obtain information about the structure and dynamic behavior of the CIS. The most effective in the case of modeling and analysis of corporate information systems with a service-oriented architecture (SOA) are colored Petri nets (CPN). CPN is a graph-oriented language for designing, describing, modeling, and managing distributed and parallel CIS. Unlike a classic Petri nets, data typing based on the color set concept plays an important role in CPN.
