“…The aggregation/grouping approach aims to facilitate the collection, sorting and harmonization of LCI data by defining a data framework or grouping data according to a set of criteria, meaning that similar materials or components are summarized, thereby reducing the effort (Table 8). Favi et al [150] created a structured model and data framework for the life cycle inventory of a generic welded structure. The data frame defines which data from the project documentation, such as welding instructions, CAD models, welding schedules, and material certificates, are relevant and provides the mathematical relationships for automatically generating the LCI based on the data.…”

Life cycle assessment (LCA) has established itself as the dominant method for identifying the environmental impact of products or services. However, conducting an LCA is labor and time intensive (especially regarding data collection). This paper, therefore, aims to identify methods and tools that enhance the practicability of LCA, especially with regard to product complexity and variance. To this end, an initial literature review on the LCA of complex products was conducted to identify commonly cited barriers and potential solutions. The obtained information was used to derive search strategies for a subsequent comprehensive and systematic literature review of approaches that address the identified barriers and facilitate the LCA process. We identified five approaches to address the barriers of time and effort, complexity, and data intensity. These are the parametric approach, modular approach, automation, aggregation/grouping, and screening. For each, the concept as well as the associated advantages and disadvantages are described. Especially, the automated calculation of results as well as the automated generation of life cycle inventory (LCI) data exhibit great potential for simplification. We provide an overview of common LCA software and databases and evaluate the respective interfaces. As it was not considered in detail, further research should address options for automated data collection in production by utilizing sensors and intelligent interconnection of production infrastructure as well as the interpretation of the acquired data using artificial intelligence.

“…), and the available studies do not always declare what is included or not. Some attempts at sectoral standardization have been made, although they have mostly focused on specific tasks, such as developing a holistic strategy (Fet et al, 2013), data retrieval and organization (Favi et al, 2019;Nam et al, 2016), the development of a dedicated tool (Prinçaud et al, 2010) or the definition of new impact eco-financial indicators (Ytreberg et al, 2021). As a result, there is room for improvement in the application of the LCA framework in shipbuilding and vessel operations.…”

“…The way to collect manufacturing information (i.e., welding) brings with it the necessity to integrate the heterogenic nature of the information that comes from different sources, which could lead to a divergent way of interpreting its meaning, causing misinformation, misleads, and errors that increase project costs and development time [11,12]. This practice is known as knowledge-based engineering (KBE) and it is able to capture engineering knowledge systematically into the design system, with the aim to support the engineering activities by the re-use of previous experience [13].…”

Welding is a consolidated technology used to manufacture/assemble large products and structures. Currently, welding design issues are tackled downstream of the 3D modeling, lacking concurrent development of design and manufacturing engineering activities. This study aims to define a method to formalize welding knowledge that can be reused as a base for the development of an engineering design platform, applying design for assembly method to assure product manufacturability and welding operations (design for welding (DFW)). The method of ontology (rule-based system) is used to translate tacit knowledge into explicit knowledge, while geometrical feature recognition with parametric modeling is adopted to couple geometrical information with the identification of welding issues. Results show how, within the design phase, manufacturing issues related to the welding operations can be identified and fixed. Two metal structures (a jack adapter of a heavy-duty prop and a lateral frame of a bracket structure) fabricated with arc welding processes were used as case studies and the following benefits were highlighted: (i) anticipation of welding issues related to the product geometry and (ii) reduction of effort and time required for the design review. In conclusion, this research moves forward toward the direction of concurrent engineering, closing the gap between design and manufacturing.
