Requirement Specifications

Over the years a lot of strategies emerged to enhance efficiency throughout the product lifecycle of complex products: knowledge management, platform and module strategies as well as integrated requirements management are only a few of the existing product lifecycle management (PLM) strategies. An integrated product model is seen as the backbone of PLM management strategies. Most product structuring approaches propose to develop a functional structure first, considering the given requirements. From this a product structure is derived, which is finally filled with developed parts and assemblies (bill of material, BOM). In early product development phases there has to be a common understanding among the involved departments and domains about the future product appearance. Products based on platform or modular strategies have a high proportion of reused parts and assemblies. Besides, new parts have to be identified, prioritized and developed according to their priority. For this process a reliable, interdisciplinary product structure is essential. Hence, an early bill of material is used to integrate engineering tasks in early development phases and to shorten identification as well as prioritization efforts. This paper proposes an approach to derive an early bill of material from requirement specifications semi automatically.

Changes taking place in project-based manufacturing emphasize the importance of agile manufacturing, product knowledge management and product lifecycle information. The paper describes dependencies between product definition and production strategy covering also other potential areas of research i.e. growth of industrial service business and development of manufacturing and supply networks. As an outcome it can be argued that more research is needed to align product lifecycle management in project-based manufacturing, as well as to cover the evolving information needs of internal and external stakeholders. Due to the increase of industrial services, also services should be included as a part of product definition; the extended product description introduces a new set of requirements that need to be taken into account as a part of product and production strategy definition.

Lifecycle Management

Recently, computational design aiding tools resources are undertaken in modern companies, enhancing high quality product definition development. However, accurate digital product descriptions are attained through multiple software applications, each one seeking to solve focused needs. Regardless significant advances, there still remains a substantial computational deficiency in how these systems interact with each other between the several PLC stages. Plural issues with different origin and nature contribute to such state, increasing the research community interest to contribute with solution that minimizes the problem. In particular, one main issue refers to product and process knowledge exchange along PLC stages. According to this scenario, and with market pressure to increase profits and reduce redundancies, an efficient coordination and management of all the activities taking place along the Production Process must be performed. Hence, promising technologies of Product Lifecycle Management are considered strategic to manage capture of product knowledge along its life, from initial conception to retirement. This paper proposes the use of an ontology to be used in a knowledge-based system, giving support to a comprehensive product model to improve integration and data exchange capabilities trough entire PLC. The capture, handle and re-use of knowledge from multiple disciplines during PLC (e.g. design, manufacture or maintenance), extending capabilities of existent product and process models is the promising main benefit of ontologies development.

Lifecycle Management

The initial core product model (CPM), developed at NIST for the support of in-house research projects, has been extended to create CPM2, intended to support a broad range of information relevant to product lifecycle management. CPM2 is a generic, abstract model with generic semantics. CPM2 gives equal status to three aspects of a product or artifact: its function, its form, and its behavior. Thus, CPM2 can support functional reasoning about a product in the conceptual stages of design, the recording and the modeling of its behavior in the postdesign stages as well as the “traditional” design phases. Three levels of CPM2 models, de-noted as the conceptual, intermediate, and implementation models, are described. Extensions of the initial CPM are briefly pre-sented. The facilities in CPM2 for building experimental intermediate systems are demonstrated and a short illustrative example is given. The full practical evaluation of CPM2 will require the development and use of implementation models.

Lifecycle Management

The notion of an open standards-based product lifecycle management (PLM) framework is gaining momentum. In this paper, we describe the idea of a standards-based collective product model (CPM) and its interaction with domain models native to typical engineering tools. A critical hurdle in the development of the CPM from domain models is assessing the compatibility of information in these native models to its corresponding standards-based representation. To address this, we use the concept of “degree-of-openness” of engineering information. This concept comprises three metrics, namely compatibility, coverage and completeness that are used to evaluate the interoperability of information in tool-specific models with its corresponding standards-based representation. We also demonstrate GT-Diagnostics, a prototype tool that evaluates these metrics. Using electrical and mechanical CAD examples, we illustrate the value of these metrics in understanding the relative interoperability of information for engineering and business decision making. Results indicate that the metrics help to identify the sources of incompatibility of information and the areas of possible improvement in the compared schemas.

Lifecycle Management

Maintainability is an important criterion for product lifecycle management (PLM). Product maintenance needs experience and skills of the product structure and operations. It can significantly improve the understanding of a product and efficiency of product maintenance using user-friendly interfaces to show product details and operations. 3D visualization technology provides a useful tool for the understanding of product and maintenance training. Product structure and the operation process can be clearly shown and run in 3D visualized user interfaces. A framework is proposed for 3D visualization-based training systems in this paper for the aid of understanding in product maintenance. The needs and implementation of the framework are discussed. Two applications are developed to demonstrate the feasibility of the proposed method.

Lifecycle Management

Product lifecycle management is an important aspect of today’s industry, as it serves to facilitate information exchange and management between most, if not all, stages of a product’s existence. As exchanged product information is inevitably subjected to multiple transformations and derivations, information transparency between lifecycle stages can be difficult to achieve. Synthesizing representations of product information across the lifecycle, by creating a lifecycle-stage-independent platform, can provide transparent access to information for both upstream and downstream applications. In this paper, we review previous and ongoing efforts using ontologies as a means to support information integration and interoperability throughout the lifecycle of a product. We propose that existing efforts can be leveraged to create an upper-tiered ontology for product information. The resulting ontology, a core model for product lifecycle information, would support the synthesis and exchange of product information across lifecycle stages, improving access to this information and facilitating lifecycle thinking. We discuss the use of ontologies as a means to create and link paradigm-independent representations. We discuss the translations that product information may face when integrated through ontologies, and the extent to which the integrity of the information can be preserved across the lifecycle. We investigate the role of information quality in the exchange and evolution of product information across the lifecycle. Finally, we discuss the application of an upper-tiered ontology, particularly the advantages offered by increased transparency and interoperability, as a means to support lifecycle thinking for mitigating a product’s sustainability impact.
