Identifikace, měření a analýza poruch E-Commerce systémů[Identification, Measurement and Analysis of the E-Commerce System Disturbances]

Contemporary economic development in following global markets advancement evokes needs to look for new methods supporting all processes enabling domestic and foreign business activities. Internet and e-commerce systems exploitation is considered to be a standard here. Various modeling techniques can be used to increase effectiveness of e-commerce systems.
