“…Integrating the output of these systems to process planning tools and vice versa is a hard quest since there is no geometrical counterpart to the technological knowledge required by the process planner (Iudica et al 1990;Dartigues et al 2007). Further, assembly process planning activities are hardly addressed in computer-aided manufacturing (CAM) or computeraided process planning (CAPP) systems and are usually delivered as isolated tasks (Kardos et al 2020); generating expert knowledge to support these systems would require an assembly information model combining the CAD model with the assembly process .…”

Product development requires sharing information of a diverse nature between several actors. Since the new products resulting from this process often require assembly as part of their manufacturing processes, it becomes necessary to promote a functional information representation for the assembly domain. Several authors have proposed different core concepts to represent the information related to assembly. However, the resulting body of knowledge is fragmented and lacks a unified concept and definition of the information this concept should contain to be broadly adopted by the academy and industry. This study aims to identify and characterize the core concepts used to enclose the assembly information (e.g., assembly features, ports, connectors, and others) by conducting a literature review in the domain of discrete manufacturing, considering the period between 1985 and 2022. It was found that the literature is rich in concepts but often diverging: a clear depiction of the assembly information required by the involved stakeholders during the whole product development process remains elusive. This work's contribution addresses this gap by identifying the perspectives from which the assembly information can be studied, and the information required to describe the assembly process fully. The resulting information requirements were used to assess the existing approaches addressing assembly information representation. These findings can be used as a base to establish a comprehensive assembly information representation in the future.

“…To this end, a constraint model could be used, where assembly operations, as well as the whole product, are resembled through featurebased representations, which constitute the macro-level problem. On the other hand, feedback from micro-level, which is represented as feasibility cuts, helps integrate the solutions to the problems into a single, efficient computer-aided process planning package [26]. Traditionally, an experienced design engineer would need to extract the properties of the suitable RAD process of the product, as well as its own features, from the associated Computer Aided Design models.…”

Despite their contributions to the financial efficiency and environmental sustainability of industrial processes, robotic assembly and disassembly have been understudied in the existing literature. This is in contradiction to their importance in realizing the Fourth Industrial Revolution. More specifically, although most of the literature has extensively discussed how to optimally assemble or disassemble given products, the role of other factors has been overlooked. For example, the types of robots involved in implementing the sequence plans, which should ideally be taken into account throughout the whole chain consisting of design, assembly, disassembly and reassembly. Isolating the foregoing operations from the rest of the components of the relevant ecosystems may lead to erroneous inferences toward both the necessity and efficiency of the underlying procedures. In this paper we try to alleviate these shortcomings by comprehensively investigating the state-of-the-art in robotic assembly and disassembly. We consider and review various aspects of manufacturing and remanufacturing frameworks while particularly focusing on their desirability for supporting a circular economy.

“…Also, new collaboration groups are forming as the Industrial Ontology Foundry (IOF) [16,17] or the European H2020 project OntoCommons: ontology-driven data for industry commons [18] in order to standardize and to support the industry with advanced data interoperability, using reference ontologies. Another problem is the need to improve the efficiency of assembly processes in the manufacturing industry, where computer-aided process planning (CAPP) is gaining importance, which aims to identify appropriate resources while minimizing the total assembly time [19].…”

Ontology-Based Analysis of Manufacturing Processes: Lessons Learned from the Case Study of Wire Harness Production

Effective information management is critical for the development of manufacturing processes. This paper aims to provide an overview of ontologies that can be utilized in building Industry 4.0 applications. The main contributions of the work are that it highlights ontologies that are suitable for manufacturing management and recommends the multilayer-network-based interpretation and analysis of ontology-based databases. This article not only serves as a reference for engineers and researchers on ontologies but also presents a reproducible industrial case study that describes the ontology-based model of a wire harness assembly manufacturing process.
