Abstract

The paper describes the availability analysis of Web systems. The analysed systems are modelled as a set of tasks that use data, obtained in an interaction with other tasks, to produce responses. System is reliable - we do not discuss the failure and repair process of the elements. We realise the functional analysis of a Web system measured by a functional availability, i.e. the probability that a client will receive a correct response within a given time limit. The metric is calculated by simulation software developed by authors and based on the Monte-Carlo technique. We model the input load by fuzzy numbers and receive a fuzzy representation of the Web system availability changes during a day. Simulation results of for a testbed system are given.
