Homme: A Modelling Environment for Multiple Applications

Procedia Computer Science, 2021

Increasing complexity in today's manufacturing and production industry due to the need for higher flexibility and competitiveness is leading to inconsistencies in the iterative exchange loops of the system design process. To address these complexities and inconsistencies, an ongoing industry trend for organizations to make a transition from document-centric principles and applications to being model-centric is observed. In this paper, a literature review is presented highlighting the current need for an industry-wide transition from document-centric systems engineering to Model-Based Systems Engineering (MBSE). Further, investigating the tools and languages used by the researchers for facilitating the transition to and the integration of MBSE approach, we identify the most commonly used tools and languages to highlight the applicability of MBSE in the manufacturing and production industry.

The definition of Integrated Information Systems is not an easy task. In consequence, the development of models is a prerequisite when trying to identify the information requirements of an organization. The complexity inherent to production environments makes the definition of a unique model infeasible. Thus, a three layer architecture is proposed as a framework for building Task, Domain and Dynamic models. Each model focuses on one aspect but all of them are needed to reach an understanding of a particular production domain. This paper introduces a series of primitive constructs that allow the definition of high level classes of models (metamodels). Specifically, it describes in detail the Function-Task Metamodel that is employed to represent the different types of activities that are performed in a Production Enterprise.

An approach that simplifies software development of the model based decision support systems for environmental management has been introduced. The approach is based on definition and management of metadata and data related to computational model without losing data semantics and proposed methods of integration of the new modules 5 10

Current manufacturing systems have a very structured production model, expecially when high complexity and precision is required, as in semiconductor devices manufacturing. In addition, rapid changes in both production and market requirements may occur, hence great flexibility is essential. This goals, together with the capability of adding new features as well as removing some model limitations, often impose to re-engineer periodically existing models, reducing as much as possible the time-to-market of a new product. Updating a model generally also requires to improve existing applications, both re-writing software components as well as adding new features to existing components. Here the model currently used inside STMicroelectronics facilities to define production flow (the sequence of operations to be performed in order to make products) is considered. First, the model is described highlighting its limitations, then an enhanced object-oriented model is introduced, in order to provide both a better management of all entites through aggregational and constitutional hierarchies and a significant time reduction of production flow definitions through a flexible inheritance mechanism. In addition, required improvements on existing applications are considered, introducing an enhanced environment capable of supporting the enhanced model while preserving both technical and economic investments thus avoiding radical changes in existing environment.

Many large software systems are tightly integrated with their physical environments and must be adapted when their environment changes. Typically, software development methodologies do not place a great emphasis on modeling the system's environment, and hence environmental changes may lead to significant and complicated changes in the software. In this paper we argue that (1) the modeling of the environment should be an integral part of the process, and (2) to support software evolution, wherever possible, the software should be automatically generated. We present a model-integrated development approach that is capable of supporting cost effective system evolution in accordance with changes in the system's environment. The approach is supported by a "meta-architecture" that provides a framework for building model-based systems. This framework has been successfully used in various projects. One of these projects, a site-production flow visualization system for a large manufacturing operation, is analyzed in detail.

Today’s competitive conditions call for detailed comparative analyzes of manufacturing processes in order to get competitive products. This analysis involves the development of faithful and robust models for the supervision and management of all organizational and operational activities of companies. Efficient modelling involves the selection and use of appropriate tools for modelling, simulation and analysis of manufacturing processes. The diversity of manufacturing processes often makes it necessary to implement specific modelling tools. MM-DSL is a platform independent language for specifying and implementing specific modelling tools. The core objective of the MM-DSL language is the implementation of the modelling method concept. The paper presents the mechanisms underlying the MM-DSL language as well as its use for building the modelling tools specific to the manufacturing systems.

This paper presents a novel modelling approach for hybrid industrial plants. It is based on the introduction of object-oriented concepts to the Differential Predicate Transition nets. To handle the system complexity a top-down methodology is considered, where class models are successively refined and decomposed. The UML language is also used to represent different views of the modelled system. A cane sugar factory is used as an example to illustrate the proposed approach.

This paper provides a survey of model management literature within the mathematical modeling domain. The first part of the survey is a review and a summary of the literature. After giving some basic definitions of modeling, modeling life cycle, and model management, two representative algebraic modeling languages followed by three approaches to modeling are introduced. These approaches are database, graph-based, and knowledge-based. The discussion is followed by a review of two specialized model management systems. The second part of the survey is a categorization of various modeling systems based on the modeling functions they provide and some of their features. These functions include life cycle support and model base administration. The degree of model independence provided by model management systems and the implemented environment systems is also summarized. The last part of the paper provides directions for future research.
