For sustainability of environment, legislations in EU, USA, Japan and Australia require manufacturers to take back their products at the End of Life (EOL) and recycle them. The concept of 6R (reduce, reuse, recycle, recover, redesign and remanufacture) is very important for this issue, while reuse has the highest energy and material recovery efficiency. In this study, an integrated product information model has been developed in UML to provide necessary information for any future decision making activities in the EOL stage, such as the replacement analysis of any used part or subassembly. This product information model represents not only product structure but its function, behavior, and their associations in different abstract levels to support replacement analysis of an existing component with a new or a used component available to company. This representation schema provides necessary information for any future decision making activities in the EOL stage, such as the replacement or reuse of any part or subassembly. In an analysis of replacement for a faulty component with a used or new component, this model provides all of the associations of the existing artifact with other artifacts and the environment, not just functional and space requirements, and the relevant modification(s) of the associated objects has to be verified.

New paradigms and accompanying software systems are necessary to support the integration of system level design and discipline level analysis activities for the implementation of product lifecycle management. An information driven product development framework has been developed to integrate these activities using product information model to represents the associativities among design requirements, product models and design parameters. In this paper, product information model is used to not only integrate all the activities and software packages, but also enable formulating and solving design problems using appropriate solution methods. Two engineering examples are solved using three different methods, Genetic Algorithm, Game Based Decision Making method, and Collaborative Decision Making method. The three methods are compared by the numbers of calls to discipline level analysis models. It was shown that collaborative decision making method is capable of finding satisfying solutions with the least number of calls to the computing expensive analysis models.

Material Information

Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material information plays a significant role in the decision making process at any stage of the product life cycle, especially with respect to the sustainability of a product. Material information in the manufacturing stages of a product’s life cycle will relate to the processes used in manufacturing and assembling individual components. The material properties may determine what processes can be used and how these processes should be controlled. To support sustainable manufacturing, the impacts of material choice should be considered during design, when resources are being committed. When comparing material alternatives at design time, it is not as simple as saying one material is “more sustainable” than another. Many different factors determine the sustainability of a product, and each of these factors may be influenced by multiple material properties represented through various information requirements. In order to develop a material information model that can satisfy these information requirements, we need to carefully study the requirements from an information modeling perspective. In this paper, we use activity models to describe design and manufacturing scenarios that rely on the availability of proper material information for sustainability decision making. We will use these models to first define specific scenarios and then to identify the types of material information that is typically required in these scenarios, and collect and categorize key concepts. Based on this study, we will make recommendations that will aid the development of a useful material information model for sustainable decision making.

Environmental Norms

Taking environmental factors into consideration is the primary demand and feature of eco-design. But the environmental factors are often numerous, trivial and related to the entire design phases, which make eco-design difficult to carry out. In order to address this problem, Product Information Model for Eco-design (PIMfE) based on the NIST CPM2 was proposed to provide an organizer and a standard representation for eco-design information. By extending the CPM2, environmental aspects, such as environmental norms, regulations, standards, material selection, disassembly, recycling and environmental impact evaluation, were integrated into product information model. Then the key activities of eco-design namely requirement analysis, detailed design and environmental evaluation could be supported by PIMfE. An example of keypad microphone is used to illustrate the suggested product information model and verify its validity.

Share Information

A lot of information needs to be processed in the MEMS design process, but this information lack the unified expression format at present. This causes the design stage of MEMS not to be able to share information, furthermore causes low design efficiency. A product information model is presented according to MEMS design stage. XML language is used to describe information of each design stage, and an information exchange and sharing platform model has been established to solve MEMS design data sharing and exchange bottleneck question. The XML technology makes the platform reusable and extensible.

As a significantly complicated manufacturing process, shipbuilding requires a sophisticated product information model to achieve the seamless flow of product information. A digital mock-up system (DMU) that builds a prototype in a computer has been proposed for consistent quality control. The DMU system can simulate models and assemblies on-the-fly as well as project real-world manufacturability without the expense and time required to make a physical mock-up. However, establishing a DMU system that can facilitate the use of product information is not easy. Preparing useful product information is costly and requires skilled computer engineers. It is thus often infeasible, especially in small and medium-sized shipyards. This paper describes the development of an affordable DMU system. Newly emerged technologies such as eXtensible Markup Language (XML), Unified Modeling Language (UML), and virtual reality (VR) are utilized to set up a practical DMU system. The DMU system developed has been applied to various commercial ships to verify its functionality and practicability.
