An integrated factor analysis model for product eco-design based on full life cycle assessment

Journal of Industrial Engineering and Management, Feb 2016

Purpose: Among the methods of comprehensive analysis for a product or an enterprise, there exist defects and deficiencies in traditional standard cost analyses and life cycle assessment methods. For example, some methods only emphasize one dimension (such as economic or environmental factors) while neglecting other relevant dimensions. This paper builds a factor analysis model of resource value flow, based on full life cycle assessment and eco-design theory, in order to expose the relevant internal logic between these two factors. Design/methodology/approach: The model considers the efficient multiplication of resources, economic efficiency, and environmental efficiency as its core objectives. The model studies the status of resource value flow during the entire life cycle of a product, and gives an in-depth analysis on the mutual logical relationship of product performance, value, resource consumption, and environmental load to reveal the symptoms and potentials in different dimensions. Originality/value: This provides comprehensive, accurate and timely decision-making information for enterprise managers regarding product eco-design, as well as production and management activities. To conclude, it verifies the availability of this evaluation and analysis model using a Chinese SUV manufacturer as an example.

Introduction Eco-design is an approach to product design that makes special consideration of the environmental impact of the product during its entire life cycle. Eco-design of a product, including any variations in ecological design patterns, has a critical impact on the status of the product’s material and value flow during its entire production process. The cost and value of the product and its associated environmental load and consumption of resources are also affected. To this effect, it is necessary to comprehensively evaluate and analyze the status of the material and value flow of a product’s life cycle so as to provide complete and timely eco-design information. There are variable comprehensive evaluation methods on the horizon, However, there are defects and deficiencies in the existing evaluation and analysis methods. For example, some methods only focus on one aspect of the product (economic or environmental factors,) despite varying degrees of impairment, moreover relatively fewer methods for comprehensive evaluation and analysis of the product system. The primary objective of this paper is to build a fully comprehensive evaluation analysis model which can trace, evaluate, and analyze the status of the material and value flow of the product life cycle process, from the three harmonization perspectives (resources, environment, and economy). Based on the concept and principle of the IPAT equation, this paper builds the total factor evaluation analysis model and creates specific evaluation by seeking a strict number of logical relationships between resource efficiency, economic efficiency and environmental efficiency. This paper also completes the analysis of the different stages of resource flow in the life cycle of products by constructing an X, Y, Z multiples evaluation factor at the core of the relationship between the product performance, resource consumption and environmental load. 2. Review on Traditional Evaluation and Analysis Methods of Product For the sake of assessment, the life cycle of a product is usually divided into four parts: procurement, manufacture, use, and disposal (Jeganova, 2004; Yamamoto & Wang, 2003) . Resource and environmental factors are crucial to the product’s design. Environmental performance goals are carefully set for the product, in order to leave minimal environmental impact (COM, 2003; Ortiz, Raluy & Serra, 2007). The objective is not only to reduce the consumption of materials and energy and the emission of harmful substances, but also to make the products and parts easily retrievable, recyclable and re-usable (Bhander, Hauschild & McAloone, 2003; Sakao, 2007) . 2.1. Standard Costs and Variance Analysis Mode This model introduces a standard cost and target cost ideology, and establishes cost standards as well as proportion standards of cost allocation for different product cost types.
