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.

Illumination is one of the important factors in machine-vision systems, and optimization of illumination is essential to acquire high-quality images during an inspection process. This paper proposes optimization process of the light color and intensity for inspection of active matrix organic light emitting diode (AMOLED) panels using a random-search method. The raw image acquired by a line scan camera had low luminance uniformity due to the surface condition of the AMOLED. The brightness deviation of the image was corrected to increase uniformity. The image quality after the correction was evaluated using a kind of image index, namely Tenenbaum gradient. The random-search method switched the dimming levels of the color source until a better image index was obtained. The random search was formulated for a multi-dimensional vector to be used in an arbitrary number of color sources. The random value in this study was generated using Gaussian random method, and was terminated when the size of a random vector became sufficiently smaller. The random-search method for automatic light control of AMOLED inspection showed 0.6% difference in the image index between the equal-step search and the proposed method. However the number of iterations in the proposed method was 22 but that of the combinations was 20484.

Autonomous grasping operations in dynamical environments are key elements of solutions for Factory-of-the-Future scenarios. The manipulator has to cope with a broad variety of objects with different shapes, materials and uncertain poses but at the same time it should provide reliable grasping and placement operations. Within this context, tactile sensors mounted directly on the grippers are a promising solution for monitoring the grasping process. They operate independently from light or line of sight configurations, thus offer a new object detection modality, besides optical-based systems. We receive an imprint of the grasped object with a spatial resolution according to the sensor pattern. However, in case of grippers with a flexible structure and material, this method generates spurious measurements if the gripper is deformed during a manipulation process. This effect disturbs the evaluation of the gripper's state or object position. In this paper, we develop the specification of a tailored tactile sensor configuration able to handle gripper deformations. Based on the results we present a proof-of-concept implementation.

The integration of the wireless network into the control loop of Networked Control Systems NCSs, given the stochastic behavior of wireless communication, can degrade the system performance i.e, its Quality of Control (QoC). It is necessary to study the implications of the communication constraints because control systems need a perfect communication medium. The performance of wireless network and its Quality of Service (QoS) must thus be analyzed in order to guarantee a good QoC. The present paper proposes an analysis of QoS performance metrics for networked systems (networked robots) using an analytic model based on Markov chain theory. The Markov model describes the IEEE 802.11 Distributed Coordination Function (DCF) for periodic round trip traffic of Wireless Networked Control System (WNCS).

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.

Industry 4.0 aims at highly flexible and digitized model of industrial production that is smarter and more reliable than the current possibilities. This requires vertical integration of different operations in a manufacturing to promote reconfigurable smart factory. This investigation proposes a method to schedule maintenance operations using formal methods considering power balance and production constraints in process industries. First, we provide an optimization model for scheduling maintenance and operation along production schedules. Second, we use timed model checking to schedule maintenance considering various physical and operating constraints. Third, we illustrate the method in a smart aluminium factory. The main contribution of this investigation is the integration of optimization models and formal methods in one framework, which leads to verified production/maintenance schedules and contributes to the objectives of Industry 4.0.

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.

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.
