The Value Analysis Method provides two ways of improving a product or service: reducing the production cost and improving the performance of the product/service by identifying potential development directions.In the present paper the authors describe the characteristics of the functional analysis phase in the Value Analysis methodology for the electrical engineering products area. Also, they propose a new method for determining the importance level of a product's functions. The functions are divided into categories corresponding to the type of energy transfer between the product and the environment. This requires a double ranking method: firstly rating the categories and secondly rating the functions within each category. The method is recommended complex products with multiple functions.In order to validate the proposed method, the authors carried out a research in Romania, on a sample of 88 respondents from the academic and industrial (electrical engineering) field.
Based on both the manufacturer's perspective (an engineering approach) and the customer's point of view (a marketing approach), the Value Analysis Method can determine both directions to reduce production cost and technological change to a product. The method allows the analysis of the possibilities to reduce manufacturing costs based on a detailed investigation of the current cost of a product. The present paper tackles the implementation of the Value Analysis Method in the manufacturing of electrical motors, with application for the flameproof motors. The authors identified four categories of flameproof motor functions: (a) strong undervalued functions, (b) strong overvalued functions, (c) slightly under / over-valued and (d) proportionately valued functions (by the manufacturer). Hence, the data on the production costs are provided by a domestic (Romanian) producer. It examines the method's potential to create solutions to increase efficiency and effectiveness of the studied motors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
