A Preliminary Methodological Approach to Models for Manufacturing (MfM)

Abstract

To enhance multidisciplinary design and simulation of complex systems, MBSE (Model Based Systems Engineering) is a methodology where computer aided graphical modeling authoring tools are used to specify functions and behaviors of the systems. Simulation tools bring about a system behavioral abstraction required for the design of complex products. MBSE enables more robust systems engineering, because it results in models and their associated behavioral abstraction. [1].A research approach for modelling manufacturing systems in the aerospace industry, and in particular for FAL (Final Assembly Line), has been proposed by the authors in several research papers during the last years [2], [3]. Functional and data models have been published and deployed using data structures available from commercial PLM systems [4].Recently a new approach for modelling manufacturing systems has been coined as an extension of the previous research to introduce MBSE in manufacturing. A new architecture based on 3-Layers Model (3LM) has been defined: a Data layer, an Ontology layer and a Service layer. Ontology layer is the core of the 3LM. The Ontology layer defines: Scope model, Data model, Behavior model and Semantic model, to further instance information from databases. Scope model is mandatory because manufacturing is a large and wide part of the artifact lifecycle and Data model can cover different several uses across it. This paper presents a preliminary methodology for Models for Manufacturing (MfM) trends and issues that can be addressed in order to support the generation and management of manufacturing ontologies.

Ontology-based system to support industrial system design for aircraft assembly

“…Another EU-funded research project has developed an end-to-end advanced platform for manufacturing engineering and PLM (amePLM) (Lentes und Zimmermann 2017), which bases on a semantic backend and supports engineering activities with its embedded modules and the possibilities to integrate various external tools via adapter agents. Particularly in aerospace industry, a preliminary approach Models for Manufacturing (MfM) with its 3-Layers Model (3LM) -data layer, ontology layer and service layer -was proposed, which inherits MBSE methodology and aims for supporting the generation and management of manufacturing ontologies (Mas et al 2018). Moreover, a Model Lifecycle Management (MLM) system supports the MfM methodology.…”

“…The service layer provides services like simulation, design space exploration, visualize, dashboard etc. (Mas et al 2018). In this paper, the service layer includes four modules: 1) the requirement management module manages the industrial requirements in requirement table ; 2) the architecture definition module serves to coordinate system architecture definition in SysML models and ontology, as well as define the trades; 3) the verification module takes the needed information from ontology layer and pre-processes it for DES model and 3D simulation model.…”

“…Though MBSE supports system development by a structural formalisms, domain specific knowledge of a complex system represented by MBSE models cannot be captured as expected (Yang et al 2021); (2) In aerospace industry, MBSE has been partially adopted during last few years. Although research and development have been conducted applying MBSE to the aircraft product design, the aircraft manufacturing filed is only gaining attentions recently, whereby several corresponding researches are mentioned in (Mas et al 2018). It still lacks solutions to meet the needs of designing an industrial system for aircraft assembly; (3) Unlike the analysis and evaluation in the context of Design-to-Product, such as supporting development of an aircraft system through a Functional Mock-up Interface (FMI) based cosimulation (Hallqvist et al 2017), Design-to-Manufacturing focuses rather on evaluation of factors in manufacturing, such as cost, lead time, etc.…”

A semantic-driven tradespace framework to accelerate aircraft manufacturing system design

“…By converging MBSE and ontology, a preliminary methodology for Models for Manufacturing (MfM) has been proposed, which includes three layers i.e. data layer, ontology layer and service layer (Mas et al, 2018). The Cognitive Digital Twin (CDT) concept has been proposed with the ambition of integrating the conventional digital twins with semantic technology, MBSE and closed-loop lifecycle management technologies (Zheng et al, 2021).…”

A Preliminary Study of Models for Manufacturing (MfM) Applied to Incremental Sheet Forming

“…The three layers of the framework are referred to as Data Base and Interfaces, Ontology and Software Tools layers. This work focuses on the development of the Ontology layer whereas aspects related to system architecture and methodological approach of MfM are further discussed in [7]. The MfM methodology is still in the preliminary phase.…”
