Trust in product data quality (PDQ) is critical to successful implementation of the model-based enterprise (MBE). Such trust does not extend to the exchange and the reuse of three-dimensional (3D) product models across the product life cycle because verifiable traceability in the product data is lacking. This assurance is especially crucial when “siloed” manufacturing functions produce the product data that is not fully interoperable and thus requires frequent reworking to enable its reuse. Previous research showed how public key infrastructure (X.509-PKI) from the X.509 standard could be used to embed digital signatures into the product data for the purposes of certification and traceability. This paper first provides an overview and review of technologies that could be integrated to support trust throughout the product life cycle. This paper then proposes a trust structure that supports several data transaction types. Then, the paper presents a case study for common configuration management (CM) workflows that are typically found in regulated industries. Finally, the paper draws conclusions and provides recommendations for further research for enabling the product life cycle of trust (PLOT).

A case study analysis of festival management is presented to determine how the tourism potential of these events can be improved. The results highlight some of the unique management problems that festival organizers face which are often a reflection of the stage of growth of the organization and stage in the product life cycle. Recommendations for festival organizers and tourism agencies are provided.

AbstractDealing with component interactions and dependencies remains a core and fundamental aspect of engineering, where conflicts and constraints are solved on an almost daily basis. Failure to consider these interactions and dependencies can lead to costly overruns, failure to meet requirements, and lengthy redesigns. Thus, the management and monitoring of these dependencies remains a crucial activity in engineering projects and is becoming ever more challenging with the increase in the number of components, component interactions, and component dependencies, in both a structural and a functional sense. For these reasons, tools and methods to support the identification and monitoring of component interactions and dependencies continues to be an active area of research. In particular, design structure matrices (DSMs) have been extensively applied to identify and visualize product and organizational architectures across a number of engineering disciplines. However, the process of generating these DSMs has primarily used surveys, structured interviews, and/or meetings with engineers. As a consequence, there is a high cost associated with engineers' time alongside the requirement to continually update the DSM structure as a product develops. It follows that the proposition of this paper is to investigate whether an automated and continuously evolving DSM can be generated by monitoring the changes in the digital models that represent the product. This includes models that are generated from computer-aided design, finite element analysis, and computational fluid dynamics systems. The paper shows that a DSM generated from the changes in the product models corroborates with the product architecture as defined by the engineers and results from previous DSM studies. In addition, further levels of product architecture dependency were also identified. A particular affordance of automatically generating DSMs is the ability to continually generate DSMs throughout the project. This paper demonstrates the opportunity for project managers to monitor emerging product dependencies alongside changes in modes of working between the engineers. The application of this technique could be used to support existing product life cycle change management solutions, cross-company product development, and small to medium enterprises who do not have a product life cycle management solution.

This research was - case study in Rstin company for the steel structures in Erbil- addressed the cost technique of product life cycle, as discussed the kinds, relevance and the stages of the life cycle of the product, also it referred to the corporate governance of discussing its inception the concept and importance of the principles, objectives, and mechanisms was addressed to the technical aspects of the overlap between the cost of the product life cycle corporate governance and show the appropriate techniques used in each stage of the life cycle of the product and how it achieved by a reduction of costs. The result of this study indicates that the integration between the product life cycle cost and corporate governance works on reduce costs through the various stages of product life cycle. It also concluded that this integration increases the company ability to compete in market which leads to rise in its market share and eventually lead to maximize the profit which has been achieved through the optimal use of a company available resources. It also found that the techniques of life cycle cost of the product cannot be applied without support of the company directors, throughout the technical requirements of the application. Corporate governance ensures directors of the company to utilize firm resources which makes the company to achieve several stakeholders' objectives.
