An Application of a DSML in Industry 4.0 Production Processes

Abstract

One of the goals of Industry 4.0 is to enable mass customization of products and to satisfy specific needs of customers. This goal is often hard to achieve in traditional manufacturing systems. To enable fast production changes, an automatic and flexible production is needed. In this context we propose a Model-Driven Software Development (MDSD) approach and a Domain-Specific Modeling Language (DSML) to model production processes. The language supports two levels of abstraction. A Master-Level (ML) model is used by a process designer to model process steps. A Detail-Level (DL) model is used by Orchestrator, a cluster of industrial computers that manages production, to fill existing ML models with a specification of production logistic and smart resources. A code generator is used to generate machine-readable or human-readable instructions from DL models. Generated code is used for automatic execution of production processes within a simulation or a shop floor. In this paper we provide an application of a DSML, which is capable of modeling production processes that are ready for automatic code generation.

The Syntax of a Multi-Level Production Process Modeling Language

“…One of the key future steps of our research will be to conduct the evaluation of the presented language. Using Modeling Tool, the language is tested by industrial process designers within an industrial use case [35], but we plan to systematically conduct the language evaluation that will include researchers and students from the academic community and process designers from the industry. During the initial MultiProLan validation, process designers were able to easily model the entire production process they needed and send the models to Orchestrator for execution.…”

Towards Trustworthy Horizontal Integration in Industry 4.0 Based on DLT Networks

“…The intended research should try to facilitate interoperability between different production systems by utilizing concepts identified in AIF and offering improvements in the way CBPs are modeled in the domain of Industry 4.0. Modeling of production processes in the domain of Industry 4.0 is essential in order to understand, control, and optimize process operations, and has been an important topic of our previous research [20]. Different notational aspects of CBP models, concerned with their expressiveness and visual representation, and the execution significance that concerns their computability by a machine, should be examined while considering different characteristics of the proposed DLT monitoring platform.…”

SysML4GDPSim: A SysML Profile for Modeling Geometric Deviation Propagation in Multistage Manufacturing Systems Simulation

“…In this context, the capability of generic simulation languages (e.g., Modelica) to verify and validate simulation models is limited to assure the syntactic correctness of the models; for example, checking that the set of variables and mathematical relationships is sufficient to obtain a solution. An interesting alternative to overcome these limitations is the adoption of domain-specific modeling languages (DSML) [6], which include the specific semantics of a studied domain, which would enable the model consistency validation based on these specific semantics. Generic descriptive modeling languages such as SysML [7] support the development of DSML, defining specific profiles that extend the language by adding stereotypes and detailing the semantics through OCL expressions [8].…”
