This article deals with the component modeling under uncertainty. A comprehensive methodology for creation of a component model based on analysis of client requirements and the identification selection of a suitable domain model is proposed here. This article presents the expert system and its methodology that is used for construction of a component model and is a suitable tool for an analysts to create finite component models and for a customer to propose his requirements and own components and to review the design. The methodology uses a system of hierarchical and parallel evaluation steps using fuzzy linguistic variables.
