As one of the main contributors to global environmental degradation, mechatronic industry must take the responsibility of improving the environmental performance of its products. Compared with further development of green technology, setting environmental protection willingly and seriously as one of the engineering optimization objectives are also important. This paper analyzes the decision making processes from the viewpoint of product life cycle and serves the purpose of reaching a balance between economic profit and environmental performance for each life cycle participator.

It is beneficial to conduct LCA(Life Cycle Assessment) during early stages of product development, as the earlier the environmental problems associated with the product life cycle are discovered, the less costly and more effective the preventing measures are. However, due to the lack of data communication tools between CAD and LCA systems, life cycle data collection during design stage is difficult. This paper presents a feature-based method of UGNX-LCA integration for sustainable product development. A feature-based multi-view life cycle model for integrating product-process-LCI (Life Cycle Inventory) data is developed based on mapping mechanism between engineering domains of product design, process planning and LCA. Data migration from UGNX models to LCA, including UG modeling feature identification, UG-LC(Life Cycle) feature transformation and LC feature model output are realized by embedded integrator. A case study of data migration from UGNX to LCA is presented to demonstrate the proposed approach.

Abstract Current research trends are extending from partially integrated product and process modeling to life cycle modeling, in order to provide a framework and methodologies based on a holistic approach for the support of sustainable product development. Within given scope we are interested to investigate, if feature technology, introduced in the late seventies and developed over the paste twenty years provides the potential, if further enhanced, to be used as a means to provide basic integration for geometry related processes and models over different product life cycle stages. In a first approach, feature neighborhoods are developed and introduced as an extension, to foster evaluation of disassembly / reassembly on grounds of feature-based product descriptions. An attempt to support product maintenance and material recycling within life cycle modeling while investigating structural dimension and limits of improved feature models as a means of geometry-based model integration.

Reduce Emissions

This article utilized a multicriterial quantitative and qualitative analysis of the influence of eco-friendly methods in reducing emissions over the life cycle of automotive products. The new proposed multicriterial method is applicable where preferential criteria are independent of each other, and where uncertainty has not been incorporated into a formal model. The linear model showed how the values of several criteria related to the options could be combined into an overall value. The main objective of this research was to apply a multicriterial methodology to improve the accuracy of existing approaches in identifying the influence of eco-friendly methods to reduce emissions over the product life cycle, and to assist decision makers in the manufacturing process. The research questions were as follows: Which one of two automotive products (“Bus” or “Truck”) has the best environmental performance (EPP)? Which one of two automotive products (“Bus” or “Truck”) has the best overall environmental performance (EPAPL)? This research provided a detailed comparative analysis of a “Crosstown bus” and a “Tractor truck”, both made at the Industrial Park Romania Brasov, Romania, using a multicriterial analysis. This article provided an answer to the first research question, whilst only presenting the results for the second question. The results of the proposed multicriterial method applications provide a decision support base for environmental managerial decisions in the field of automotive production processes.

Product variety and improvements are the most important issues of today’s product development. Product family engineering is considered to be an effective approach to create new products that apply variability with decreased costs and time. However, given the environmental considerations, this study proposed sustainable product family planning which is a systematic design framework of product function; structure and lifecycle options (i.e. reduce, reuse and recycle). First, relationships between the diverse customer needs, product’s technical attributes and physical architecture are analyzed. Based on the analysis, certain product family plan including a product model change plan, a general product structure model, technical specifications and lifecycle options of each product in the family are established. A life cycle simulation tool is then developed for 1) easy building of various production strategies, product use scenarios and market competition cases, etc.; and 2) environmental and economic evaluations of the product family plan. A case study of personal computers (PCs) product family planning demonstrates an implementation of the proposed methods.

Sustainable Product

Sustainable product design plans the entire life cycle of a product from its raw material selection, conceptual and structural formation, manufacturing processing, and usage to its end-of-life, reuse, and recycle. The product design needs the sustainable knowledge and proper tools. Current computer-aided design systems are insufficient to represent complex relationships of product functions, structures and life cycle options. It is required for design tools to support product life cycle planning with multi-objective optimal solutions. In this paper, our experience in design of a wheelchair is used as an example to discuss the need of design tools. The aim is to define ideal tools for design of sustainable products.
