Augmented Reality (AR) applications gain more and more relevance in various industrial applications, e. g. for product presentations, education, engineering, etc. In the industrial domain, especially in process supervision applications, a number of standards and guidelines have been established to ensure that the design of user interfaces meets the safety requirements of plants or factories. Hence, we seek an evaluation if these guidelines can be applied to AR applications. In this paper, we present the first preliminary results of a case study on the application of those standards to a visual AR application for in-field inspection and servicing scenarios.

A novel autotuning procedure is presented through application to an industrial in-line pH control system. The procedure has three advantages over classical relay auto-tuners: experiment duration is very short (no need for limit-cycle convergence); all data is used for identification (instead of only peaks and switch instances); a parameter uncertainty model is identified and utilized for robust controller synthesis.

This paper deals with estimation of thermal conductivity for temperature control of an aluminum plate considering radiative heat transfer. Aiming at accurate control results, model-based control method needs true values of plant parameters. In our previous research, the nominal values of plant parameters have been used for temperature control experiment. However, for the actual environment in industrial field, physical parameters such as thermal conductivity will change. Therefore this paper reports the estimation result of thermal conductivity of aluminum plate considering radiative heat transfer through experimental data.

Surface cleaning and blasting for the ship hull of oil tankers and passenger ships are conventional operations in a ship yard with surface roughness requirements. Several process parameters affect the blasting quality outcome, such as the distance between the blasting nozzles and ship hull, feed rate of copper grit, grit size, etc. In this paper, a mathematical model is derived to describe the relationship between several input parameters and blasting quality. In addition, a blasting experiment is designed using the Taguchi method in order to reduce the number of experiments required for validating the proposed model. Due to resource and time constraints, the experiments will be carried out as future work.

The basis for the fourth industrial revolution is the availability of accessing all relevant information in real time by connecting all instances involved in the value chain. The ultimate goal is to manage the entire value chain process, improving efficiencies in the production process and coming up with better products and services. The essence of vertical networking comes from the use of cyber-physical production systems (CPPSs) and vertical integration from sensors to the business level of the company. But in order to assure global interoperability, it is mandatory to use industrial standards to model the different views of stakeholders and communicate heterogeneous devices. This paper focuses on the field of process industry, particularly on the oil production process. A modeling approach based on industry standards is proposed. The final goal is to generate, from the models of the plant and data supplier devices, the OPC UA server configuration. The approach has been tested to model part of the Petroamazonas EP Company located in Ecuador.

In distributed model predictive control, accounting for the interactions of subsystems requires exchanging information between controllers. However, challenges arise when controllers may lose the synchronization and when shared information may encounter the divergence due to the switching topology and the imperfection in communication. Managing divergent (or outdated) information is considered in this paper as a consensus problem and solved by an asynchronous consensus protocol. This approach based on multi-agent system paradigm to distributed control requires each controller to agree on some data values needed during action computation with its neighbors. Under certain assumptions, the convergence of consensus protocol is analytically obtained with various communication patterns (for example, directed and delayed communication). As a result, the performance of control system is improved in comparison with the decentralized strategy, and approached to the distributed strategy with sequential timing. Some simulation examples are given to illustrate the efficiency of this approach for the control of irrigation canals modeled by the Lattice Boltzmann method.

In this paper a flexible robot system for assembly operations in a semi structured environment is proposed. The system uses a moveable robot equipped with an arbitrarily mounted 3D camera and a 2D camera on the robot gripper for accurate object detection. The system is developed based on the Robot Operating System (ROS) and uses the state of the art trajectory planner MoveIt for collision free robot motion planning. The object recognition for the system is performed using a combination of the two camera's and robot end effector and the deviation of objects in the robot workspace is found to be in the range of 2.2 mm along X and Y axes. Furthermore, an implementation procedure of the proposed system for assembly task is explained.

Industrie 4.0 as one of the leading research and development initiatives for factory automation systems envisions a hierarchy of Industrie 4.0 components that exhibit a generic structure and behavior related to its utilization within production system life cycles. Each component is equipped with an administration shell containing a virtual representation of its characteristics. However, it is still unclear what kind of information the administration shell must contain. The granularity and the explicit information type must be determined. This paper provides an answer to this question by establishing a theoretical framework classifying Industrie 4.0 components. Criteria will be identified that make it possible to assign any Industrie 4.0 component to a specific production system hierarchy level and serve as meaningful administration shell descriptors.

Time Synchronized Channel Hopping protocol (TSCH) belongs to the new low-power MAC protocols included in IEEE 802.15.4e with better properties as a multihop network in industrial applications. An open issue in the standard is how to build and maintain the communication schedule. In this paper we have implemented a minimal recommended configuration and tested it against one proposed centralized scheduling optimization mechanism in a real WSN application.

Diagnostic facility is one of the most important critical resources in the hospital. Patient scheduling plays an important role in managing these facilities, especially when they are shared between regular and emergency patients. Due to the non-stationary emergency arrival and waiting time targets of emergency patients, it is challenging for hospital managers to make appointment scheduling decision and real time scheduling decisions, i.e., how many regular patients could reserve the service and how to coordinate the service of both types of patients. To deal with this problem, this paper proposes a stochastic integer programming model by considering the uncertainty of emergency patients and their waiting time requirement. The objective is to minimize the weighted idle time, overtime, and patients' waiting time. Monte Carlo optimization is used to solve this model. Numerical experiments are proposed to show the usefulness of the proposed model for investigation of the influence of different parameters.
