A cyber-physical system integrates capacities such as computing, storing and communication along with others in the physical world such as objects tracking and/or objects controlling. According to the IIoT concepts it is possible to infer that CyberPhysical Production Systems (CPPS) systems are normally connected to each other, and also connected to the virtual world of global digital networks. That is why introducing the IEC-61499 standard, will allow the CPPS to implement distributed, flexible and reconfigurable controllers. All this with the aim that industries being more competitive, which are constantly taking decisions in different industrial systems gaining in complexity, this can be improved applying qualitative and quantitative methods like the Fuzzy Analytical Hierarchy Process (FAHP). For this reason, it is necessary to provide the industry with low-cost alternatives which could redirect the CPPS development to a new variety of devices. This paper proposes the development of the FBs networks needed in the control of industrial processes based on the AHP methodology, broadly used in decision making.

In this paper, a four-phase approach for Integrated Procurement-Production (IPP) tactical planning in a multiechelon, multi-product and multi-period Supply Chain (SC) network is proposed. To account for ambiguity and vagueness in some real-world data and preferences, in the first phase of the approach, the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (fuzzy TOPSIS) method is used to obtain the overall performance and risk ratings of the suppliers with regard to a set of qualitative and quantitative criteria. In the second phase, we introduce a novel multi-objective possibilistic mixed integer linear programming model (MOPMILP) for solving an IPP planning considering conflicting goals simultaneously: maximization of the overall performance and minimization of the overall risk. Then, after converting this MOPMILP model into an equivalent crisp multi-objective mixed integer linear programming (MOMILP) model, we use the Goal Programming (GP) approach to solve this MOMILP model in order to find an efficient compromise solution (i.e. an efficient procurement production plan) for the whole SC. The proposed approach and solution methodology are validated through a numerical example.

During the life cycle of an industrial processing plant, a variety of domain specific data models are generated. All these models will be changed independently by a group of engineers over time. Maintaining the consistency of these models involves a time consuming and costly manual process. Here we introduce an interactive roundtrip engineering system for processing industry environments. The system use a complementary rule-based transformation language to provide generation and synchronisation processes. For this, an interactive concept is presented with a knowledge-based system and user interaction. The goal is to have a consistent digital twin of the plant through the whole life cycle in a highly automated manner. This leads to a traceable transformation process which ensures more parallel design phases and an efficient maintenance or reconstruction of the digital plant twin.

A joint research between Politecnico di Torino and COMAU is going on, aimed at defining a task oriented programming approach to allow soft skilled programmers to develop optimized programs for complex robotic cells. Within this paradigm, the user is simply asked to specify the features of the robotic cell and a structured set of tasks defining the required process. The paper is focused on the first step necessary to achieve the overall goal, i.e., the definition of a generic task model. The model is built starting from the analysis of the most important industrial applications, and can include physical and synchronization constraints, as well as various possible requirements and situations relative to the characteristics of the robots in the cell and of the involved work-pieces. A welding process is considered as typical industrial case study, to show how to build the corresponding task model according to the proposed approach.

Ethernet is a promising candidate for networking real-time embedded systems such as automobiles, and it is already used in several embedded scopes, such as airplanes and trains. Moreover, its higher bandwidth enables applications made of dispersed embedded systems that exchange large amounts of data through the so-called Internet-of-Things, such as wide-area video sensing. In this realm, network reservations are an important design element that favor composability in the time domain thereby supporting the design of complex systems. However, reservations may impact negatively on the network bandwidth efficiency due to over-specification, particularly when they are designed to meet worst-case delay constraints. In this work, we use a specific Ethernet protocol that provides real-time reservations, namely FTT-SE, and we assess through extensive simulations the efficiency of a worst-case network delay analysis for sporadic reservations associated to asynchronous messages. Essentially, we compare the analytical worst-case delay with the one observed in the simulations using two data sets comprising up to 20000 and 100000 message sets, respectively, and we change the system configuration, namely properties of the message sets and network and protocol configuration parameters. We find that the analysis is accurate, i.e. matches observations, for a significant percentage of messages in the message sets (up to 60% on average). Conversely, we found that a small percentage of message sets (below 6%) generated rather pessimistic analytic estimates exceeding the observations by 6 times, thus with a negative impact on efficiency. The results we present in the paper, particularly their distributions, inform system designers of how to tune their designs to improve network bandwidth efficiency under strict timing constraints.

To cope with the increasing quantity of wires, thus the weight and integration costs in avionics, an implementation of a new avionics communication architecture with less cables will clearly improve the efficiency of aircraft, while reducing the deployment costs. Furthermore, such a communication architecture shall be efficient to meet the design requirements, in terms of predictability and availability, for the least amount of money. Therefore, the AFDX compatibility, a minimized (re)-configuration effort and costs are among the most important issues to guarantee. On the other hand, the recent research effort towards defining new communication solutions, to guarantee a high availability level with limited cabling complexity for realtime applications, has renewed the interest in ring topology. Therefore, the main objective of this paper is benchmarking the most relevant solutions, based on Ethernet technology and supporting ring topology, vs avionics requirements, and we particularly focus on the main Performance Indicators, specified in IEC 61784-2, of each one of them.

Industrie 4.0, Industrial IoT, and cyber-physical production systems in general introduce high levels of automation. Hence, at shop floor level, for example, the interfaces between human and machines are crucial. If a robot's environment perception is not robust and fail-safe, humans may not be detected properly, which may cause critical consequences. However, given the resource constraints of safety controllers typically used in critical application domains, the implementation of complex computer vision algorithms is often challenging. Here we explore the capabilities the indirect Time-of-Flight environment perception technology provides in order to speed up complex computer vision algorithms. In particular we are investigating the use-case of human detection in the domains of critical and resource-constrained applications, such as factory automation and automotive. We demonstrate that preprocessing based on Time-of-Flight 3D data can reduce computation time of typically used computer vision algorithms, such as Viola-Jones, by up to 50%. Furthermore, we showcase a human detection demonstrator case-study implemented on an AURIX processing system that represents a state-of-the-art safety controller. By exploiting the Time-of-Flight technology's depth and amplitude data in a clever way, safety-critical human detection is enabled on the AURIX platform. Compared to competing environment perception technologies, the outlined solution is hardly achievable with structured light or stereo visioning due to the safety controller's resource constraints.

Hardware-in-the-loop (HiL) Simulation is a powerful method to reduce the risk of system failures leading to expensive damages. Many existing HiL tools require the tester to use proprietary test specification languages, usually unknown to the domain of a PLC programmer. This work presents a novel approach of HiL test specification using programming languages specified by IEC 61131-3. By doing this, PLC programmers are able to specify test cases in the domain they are already familiar with.

This paper is dedicated to the growing role of dependability assessment for wireless networks in industrial automation systems in particular with respect to future flexible production processes. First an overview is given over definitions of dependability and its parameters. Terms are classified in order to derive the key terms for wireless communication with respect to automation applications. Dependability parameters for assets of wireless communication are discussed. Relevant dependability parameters including an up state function (USF) is proposed. The USF can be used in order to assess the dependability of complex wireless automation applications independent of wireless technology. The use of the USF is demonstrated with exemplary measurements of a wireless LAN system.
