Towards a Model-Driven Architecture Process for Developing Industry 4.0 Ap

Abstract

Emerging technologies in the industrial area lead to continuously increased complexity concerning systems development. Varying approaches dealing with the same problem generate a number of heterogeneous solutions instead of concentrating on a mutual toolset in order to provide a common basis. Having recognized this problem, the German industry introduced the Reference Architecture Model for Industry 4.0 (RAMI 4.0), proposed in the standardized technical specification DIN SPEC 91345. Providing a three-dimensional model on how to structure industrial systems, the starting point for the discussion on how to deal with the upcoming complexity has been set. However, due to the current state of research, only the frame to work in has been specified. In this paper the idea of following an approach based on Model-Driven-Architecture (MDA) in order to develop future industrial systems is introduced. To achieve this, firstly the concepts of RAMI 4.0 are analyzed and a detailed description regarding their applicability for developing specific architectures is given. The approach itself and its application are demonstrated by a real-world case study, which is created with the help of the RAMI Toolbox.Index Terms-Model driven architecture (MDA), RAMI 4.0, systems engineering, process modeling.

Mathematical Models for Order Batching and Assignment in a Deep-Frozen Warehouse

“…Three different scenarios are considered for experiments: In the first scenario, each order contains only one item, we refer to this set of instances as Single. In the second scenario, each order contains a random number of items in the interval [1,5], we refer to this set of instances as Middle. In the third scenario, each order contains a random number of items in [1,10], we refer to this set of instances as Multiple.…”

“…An optimized warehouse management system (WMS) is nowadays at the basis of a successful business. Intelligent systems utilizing operations research and advanced analytics techniques are needed to enhance efficiency [1]. For example, it is estimated that the overall picking process typically represents 60% of total cost in a warehouse operation [2] and approximately 50% of a picker's time is spent in traveling with/without articles [3].…”

Towards a Domain-Specific Approach Enabling Tool-Supported Model-Based Systems Engineering of Complex Industrial Internet-of-Things Applications

“…Theoretically, as Lake explained, the development of such a complex system needs to be structured according to the phases of its life-cycle in order to prevent confusion, misunderstanding or even conflict [31]. This is why the authors of [32] originally proposed a process model for developing Industry 4.0 applications based on RAMI 4.0, which is extended according to novel advances in this work. To give a small excerpt, Figure 3 provides an overview of how the process model correlates with the architecture definition.…”

Manufacturing Execution Systems for the Food and Beverage Industry: A Model-Driven Approach

“…Leal et al [48] developed a model-driven approach (smartHMI4I4) providing reusable Application Programming Interface (API) and widgets as a global framework to guide the HMI design and generation for different devices across Industry 4.0 application scenarios. Binder et al [49] proposed a model-driven system development process integrating RAMI 4.0 to provide a common basis for the development of Industry 4.0 systems reducing the complexity of engineering processes and heterogeneity of platforms and toolsets.…”
