Three times Value Analysis

In our society everything revolves around the notion of VALUE. In engineering the Value is the judgment made on the product, based on user expectations and motivations, expressed by a dimension that increases or remains at least equal when the satisfaction of user needs increases and/or the product related expenses decrease. This paper presents: 1-a concrete example of modular design, using the Value Analysis approach in a concrete case related to the machinery for crushing materials, 2-a modern and original method for optimizing the selection of a manufacturing process for a part, for maximizing its performance and minimizing its cost, to attain the sustainable development objectives, using Value Analysis approach, 3-a modern and original method for optimizing the selection of the material needed to obtain a new product ¿ for maximizing its performance and minimizing its cost ¿ to obtain the sustainable development objectives. From here the name of the book: Three times Value Analysis Consciously or unconsciously, many people, engineers, designers, researchers, business people, politicians, etc., ... believe, think and act according to the principles of Value Analysis.
