Construction similarity in the process of creating ordered construction families

Purpose: Theory of construction similarity has its roots in the theory of physical similarity. The model in the theory of construction similarity is a model construction. Model in the theory of similarity of construction and technology is construction and technology standard. Design/methodology/approach: The fundamental aim of the work is the selection of design features in particular type sizes of series of types that allows obtaining physical, stereomechanical and simple states that are identical as in the model construction. The basic form of the record of series of construction types is program and relation parameterization. Features are determined for the items stored in the form of series of construction and technology types. Research limitations/implications: Analysed methods develop algorithmisation of engineers and technologists environment and support integration with the process of preparation the production. Practical implications: Described methods were being developed on practical examples of creating the series of types of hydraulic cylinders used in mining. Originality/value: Method of the constructional similarity, technological similarity presented in the paper are basis of selection of design features in the process of series of types and module systems of constructions and technology creating. All of these methods support intensive development of the types of technical features and affect on their competitive on the ready market.
