Knowledge integration and sharing for collaborative molding product design and process development

This study presents a systematic approach to developing a knowledge integration and sharing mechanism for collaborative molding product design and process development. The proposed approach includes the steps of (i) collaborative molding product design and process development process modeling, (ii) an ontology-based knowledge model establishment, (iii) knowledge integration and sharing system framework design, (iv) ontology-based knowledge integration and sharing methods development, and (v) ontology-based knowledge integration and sharing mechanism implementation. The mechanism can support collaborative molding product design and process development by providing functions of knowledge integration and sharing. Results of this study facilitate the knowledge integration and sharing of collaborative molding product design and process development to satisfy the product knowledge demands of participants, and thus increase molding product development capability, reduce molding product development cycle time and cost, and ultimately increase molding product marketability.     

Risk evaluation of customer integration in new product development under uncertainty

This study mainly focuses on the risk evaluation of customer integration in new product development. Customer integration in product innovation projects has been widely recognized a best practice to enhance innovation success rate and reduces the development cycle time, but it also has many potential risks including loss of know-how, much dependence on customer, and limitation to incremental innovations, etc. Unfortunately, there are few researches about risk evaluation for customer integration which is important to the risk management of the co-innovation process. Further, evaluating customer integration risk involves much subjectivity and vagueness. To manipulate this problem, a novel evaluation approach for assessing customer integration risk under uncertainty is proposed. The novel approach integrates the merit of rough set theory in handling vagueness and the strength of group analytic hierarchy process (GAHP) in modeling hierarchy evaluation. Finally, an application in a project of mobile phone development is provided to demonstrate the application and potential of the methodology.     

Knowledge networking to support medical new product development

New product development (NPD) in the pharmaceutical industry is very knowledge intensive. Knowledge generated and used during medical NPD processes is fragmented and distributed across various phases and artifacts. Many challenges in medical NPD can be addressed by the integration of this fragmented knowledge. We propose the creation and use of knowledge networks to address these challenges. Based on a case study conducted in a leading pharmaceutical company, we have developed a knowledge framework that represents knowledge fragments that need to be integrated to support medical NPD. We have also developed a prototype system that supports knowledge integration using knowledge networks. We illustrate the capabilities of the system through scenarios drawn from the case study. Qualitative validation of our approach is also presented.     

基于产品生命周期信息集成的研究

From integration to composition: On the impact of software product lines, global development and ecosystems

Three trends accelerate the increase in complexity of large-scale software development, i.e. software product lines, global development and software ecosystems. For the case study companies we studied, these trends caused several problems, which are organized around architecture, process and organization, and the problems are related to the efficiency and effectiveness of software development as these companies used too integration-centric approaches. We present five approaches to software development, organized from integration-centric to composition-oriented and describe the areas of applicability.     

Knowledge-based integrated product design framework towards sustainable low-carbon manufacturing

With a global challenge on the serious ecological problems, low-carbon manufacturing aiming to reduce carbon emission and resource consumption is gaining the ever-increasing attention. Due to the significant impact on the product lifecycle, low-carbon product design is considered as an effective and attractive approach to improve the eco-market trade-off of electromechanical products. Existing low-carbon product design approaches focus on solving specific low-carbon problems, and how to explore and navigate the integrative design space considering low-carbon and knowledge in a holistic perspective is rarely discussed. In response, this paper proposes a knowledge-based integrated product design framework to support low-carbon product development. An ontology-based knowledge modelling approach is put forward to represent the multidisciplinary design knowledge to facilitate knowledge sharing and integration. Subsequently, a function–structure synthesis approach based on case-based reasoning is presented to narrow down the design space to generate suitable design solutions for achieving desired functions. A multi-objective mathematical model is established, and the multi-objective particle swarm optimization is adopted to solve the low-carbon product optimization. Furthermore, a decision-making ranking approach based on the closeness degree is employed to prioritize the potential solutions from Pareto set. Finally, a case study of low-carbon product design of hydraulic machine is demonstrated to show the effectiveness.     

A collaboration model for new product development through the integration of PLM and SCM in the electronics industry

As customer requirements for high-tech products vary and become complicated, the lifecycle of these products becomes much shorter. In response to this market environment, many manufacturing companies have established a global simultaneous launch strategy for new products to occupy markets before competitors. In this process, careful scheduling of the global simultaneous launch strategy is critical. In particular, to meet the launch schedule for each country in which a new product will be released, a collaboration process among relevant departments must be prepared, and correct product information should be maintained among major cooperative work support systems according to new product development business processes. This paper suggests a collaboration model integrating product lifecycle management and supply chain management as an approach to supporting complicated new product development procedures. We use a practical case study to evaluate this model.     

A Web-enabled product definition and customization system for product conceptualization

Abstract: Owing to rapidly changing customer needs and much shorter product life cycles, for developing a successful product it is imperative to employ more efficient and flexible approaches for product conceptualization. To meet this demand, a Web-enabled product definition and customization system (PDCS) is proposed, from a design-knowledge-handling viewpoint, in this paper. It comprises two phases, namely product definition based on the laddering technique and a novel design knowledge hierarchy, and product customization based on an integrated methodology of conjoint analysis and Kohonen association techniques. Basically, this system is a method of conducting design decision-making via customer involvement, i.e. a strategy for transforming customer preference into a specific product concept. A case study on wood golf club design is used to illustrate and validate the proposed Web-enabled PDCS.
