A systematic literature review to explore traceability and lifecycle relationship

Traceability is the ability to follow a product along its lifecycle. It ensures product safety and quality along the supply chain, managing information generated by several players. Even though regulations establish the information that has to be traced, each player generates much more product (and process) information, which could be used to add value to products, with respect to, not only traceability, but also the lifecycle approach. However, the concepts do not appear to be immediately related in scientific panorama. This paper aims to explore the relationship between traceability and lifecycle through a systematic literature review. Six industries (Software, Manufacturing, Automotive, Automation, Aircraft, and Aerospace) and seven subject areas (Software engineering; System engineering; Industry 4.0; New product development; Process management; Data Management; and Environmental sustainability) were identified through bibliometric analysis. To better explore this relationship in the context of the food industry, a content analysis on lead papers’ sample was performed to identify traceability and lifecycle definitions, methodologies and technologies and their relation. The results of the work, synthetised in a proposed research map, will be of interest to those who are approaching the subject for the first time, and for companies involved in product lifecycle management and food traceability.

A unified product structure management for enterprise business process integration throughout the product lifecycle

Information availability is a key factor for business success and competitive advantage. While created by design engineers, product structure is accessed and referenced by other users involved in product lifecycle from various departments. However, there is a lack of efficient ways of managing product structure information for enterprise business process integration. This study proposes a unified product structure management model to fill in this gap. With this proposed model, the product structure is managed in a unified way and can be accessed by different people with various disciplines in the right formats throughout the entire product lifecycle, including business processes of quotation, sales order processing, design, planning, scheduling, production, and delivery. This research is part of the enterprise business information management system project whose purpose is to streamline the information management for key business processes to integrate multi-disciplines in an enterprise for product development. A prototype system has been implemented to verify the model developed by taking real cases in a mould-manufacturing company. The results show the potential for substantial improvements in industrial competitive advantage.     

Challenges in integrating requirements management with PLM

Nowadays, requirements management (RQM) is mostly not included in the current structures of product lifecycle management (PLM) systems, although RQM has become a critical activity throughout the PLM. Customer requirements with all related product information need not only be integrated with each other, but with all processes and stakeholders involved through the related business functions of product lifecycle. In this paper, we examine the various challenges of RQM, especially related to PLM. Company-specific challenges are identified, when integrating RQM with PLM in a case company acting in the automotive industry. The objective of this study is to find out how product-related information on customer requirements could better be utilised and integrated with PLM. We propose a new integration framework according to which the challenges at different integration levels are categorised. As a final conclusion, the study shows the core points where and how the concepts of PLM and RQM should be developed, as to create requirements integrated solutions for extended products and systems through the lifecycle.

The integration of lightweight representation and annotation for collaborative design representation

Today companies face the unprecedented challenges of a global market, collaborative environments and the concept of management of the entire product life cycle. In supporting this, the challenge is not only how to utilize information management policies, but also how to develop product representation methods to meet the new demands including platform/application independence, support for the product lifecycle, assisting generation of viewpoint-specific representations, rapid sharing of information between geographically distributed applications and users, and protection of commercial security (intellectual property). This paper proposes a product representation approach using the strengths of lightweight representation and annotation and markup practices to allow the association of product data from throughout the lifecycle with the geometric form of the product. The approach, called Lightweight Model with Multi-layer Annotation (LIMMA), integrates the concept of lightweight representation with annotation of boundary-representations (b-rep) of a product and the use of a formalised markup language (XML). Examples of annotation layers and development of models through-life are given, based on the LIMMA approach.

Analysis and modelling of intertemporal relationships in lifecycle design: a case study for investment goods

The relevance of integrating the features of product operation and disposal in product design is growing very strongly in the business-to-business sector, as the purchasers of long-life products increasingly base their buying decision on a lifecycle ??prism??. Within the lifecycle several relationships exist, which may be of oppositional or complementary nature and face the designer with the problem of making decisions crucial to the entire lifecycle. This paper suggests an approach to modelling several cost interdependencies between different lifecycle stages, as available models of lifecycle design do not include these relationships. This developed approach was validated in a case study focused on the design improvement of an investment good aiming at the lowering of operating costs. The case study confirms the structure of the modelled relationships and delivers the first detailed analysis of the relationship between design costs and operating costs.     

Methods for the capture of manufacture best practice in product lifecycle management

The capture of manufacturing best practice knowledge in product lifecycle management systems has significant potential to improve the quality of design decisions and minimise manufacturing problems during new product development. However, providing a reusable source of manufacturing best practice is difficult due to the complexity of the viewpoint relationships between products and the manufacturing processes and resources used to produce them. This paper discusses how best to organise manufacturing best practice knowledge, the relationships between elements of this knowledge plus their relationship to product information. The paper also explores the application of UML-2 as a system design tool which can model these relationships and hence support the reuse of system design models over time. The paper identifies a set of part family and feature libraries and, most significantly, the relationships between them, as a means of capturing best practice manufacturing knowledge and illustrates how these can be linked to manufacturing resource models and product information. Design for manufacture and machining best practice views are used in the paper to illustrate the concepts developed. An experimental knowledge based system has been developed and results generated using a power transmission shaft example.
