Total performance analysis of product life cycle considering the deterioration and obsolescence of product value

Abstract

Environmental consciousness has gained more and more interest in recent years, and product life cycle design that aims to maximise total performance while minimising its environmental load and costs should be implemented. To achieve that, the rise and fall in product value along life cycles should be evaluated properly. This paper proposes a practical evaluation method for the product value along life cycle by correlating it with product functionalities, and design guideline for maximising product performance through product life cycle with balancing its value, environmental load, and costs.
