Abstract: This paper presents a new methodology for providing insight into manufacturing using key performance indicators (KPIs), and to achieve a Smart Manufacturing (SM) using a simple indicator. This indicator is very easy to understand for factory owner, production manager and installation staff, and so on. It is Smart Manufacturing Kaizen Level (SMKL). I4.0 was announced by Germany in 2011. Also, Industrial IoT and SM has become a global trend now. Various consortiums related to this trend have been established in each country, such as PI4.0, IIC, RRI and IVI. There are very significant discussions in every consortium. However, there are some issues to achieve a SM. First, it is difficult for factory owners to understand the Return on Investment (ROI), and to make the decisions of continuous investment. Second, especially for Small and Medium Enterprises (SMEs), the company has few or no IIoT experts and only limited consultants who can support the SM. By using SMKL, factory owner will be possible to understand the ROI, and to make the decisions of continuous investment. In addition, SM system can be easily constructed by using the international standardization technology for industry (OPC UA, FDT®, PLCopen®, AutomationML). In this paper, we propose a use case for SMKL and created a demonstration using miniature machines and 3D simulator and proved the effectiveness of our proposal. Also, it is concluded that SMKL use case takes important role to assist the MBSE approach for SM.

Abstract: Expanding (of) ICT, machines and its components are (able to be) connected with cloud, data base and data center. In the field of machine condition maintenance, future smart maintenance technology activities called smart maintenance 　with CBM (Condition Based Monitoring) are working on. The overview of smart maintenance and signal processing method are introduced.　For following smart maintenance, development of evaluation method is required. Because CBM criteria is based on machine component domain like design information, machine component operating data and machine component condition. Further, there is a problem that it is difficult to uniformly set a criteria because a mechanical component operation is depending on an operating condition and its environment. In this paper, new initiatives of evaluation method for smart maintenance are proposed.

Abstract: For realizing Smart Manufacturing, utilization of Internet of Things (IoT) is being greatly advanced. IoT for industrial use is called Industrial IoT (IIoT), and widely applied in the infrastructure-based industries such as petrochemical plants, water supply and wastewater management, and building management etc. IIoT has been enabled to connect various devices and equipment installed in the field (Physical space) to the data era (Cyber space) via the network,and construction of next-generation system with such connections has been progressed. Such a system is called Cyber Physical System (CPS), and various data from the connected devices are collected, stored, processed, and fed them back to the system to improve the system efficiency. In order to construct a more advanced CPS, it is necessary to connect more field devices to the system and collect more data. Therefore, IIoT devices which is installed to CPS has been facing complicated requirement such as, connectivity which enables existing devices to connect to the system, robustness which support long-term continuous operation of the system, and spindle-less which can minimize system downtime due to preventive maintenance and repair.

Abstract: Business owners of control systems have to ensure their system operations are protected from various security threats. Especially for control systems in critical infrastructures, business owners should deploy security countermeasures that fulfill mission assurance to continue their business function. The purpose of this paper is to introduce security measures that enable business continuation along with satisfying mission assurance. The proposed security introduction framework in this paper enables business owners of control systems to obtain exhaustive security measures from the viewpoint of technical, operational, and management aspects with reasonable effort. The proposed security introduction framework can be applied to a wide variety of control systems.

Abstract: To identify cyber threats is critical for securing industrial control systems (ICSs) effectively. However, it is difficult to identify threats for target ICSs without knowledge of cybersecurity professionals and hard for ICS engineers to achieve the process. This process can be automated with "cyber attack emulation" technology. The key components to realize cyber attack emulation technology is threat modeling methodologies and application of them. This paper provides a possible framework for ICS cyber attack emulation based on threat modeling methodologies.

Abstract: If industrial assets such as programmable logic controllers (PLCs) and field devices such as sensors and actuators, which make up control systems, are networked via the IoT (Internet of Things), cyber-security measures will become an issue. To implement effective security measures, configuration management of each asset is important. It is therefore a goal to appropriately manage information concerning the installed software and settings information related with the network and system passwords. Unlike IT systems, however, control systems consist of a multitude of assets, which are difficult to systematically manage. It is also a problem that when the asset-configuration management is automated, the original control function may be hindered. In this study, therefore, we model various asset-configurations for a control system and design a data structure based on SCAP (Security Content Automation Protocol). We also propose an “asset-configuration-management agent” that incurs low processing load. As a result of prototyping and evaluating this agent, we have demonstrated that (i) its effect on real-time control can be suppressed and (ii) asset-configuration management can be automated.

Abstract: Recently, cyber security of safety instruments systems (SIS) are become important issues. SIS has a critical roles to protect industrial plants and industrial automation control systems (IACS). If security threats make the safety functions disabled and degraded, serious or fatal accidents would occur in the plant. Even without an accident, the threats could down its operation of manufacturing or degrade social infrastructure services. SIS which is a part of IACS shall perform two functions, functional safety and cyber security. To achieve both functions in IACS has been a difficult problem because each has been based on independent technologies and standards. IEC TR 63069: 2019 had been developed to report a technical study on the compatibility between them, and described the terms, concepts and development. However, IT/OT (Information Technology and Operational Technology) cooperation was not yet sufficiently discussed because of the lack of experiments. For example, modifications, impact analysis, patch managements, incident response and plan to recover. This paper considers the cooperation functions of IACS during incident response against cyber attack, and especially proposes IT/OT operational functions of IACS engineering tool.

Abstract: In a control system, a network is often constructed because a central monitoring room monitors the status of control devices and sensors arranged in a wide area. Information from control devices and sensors is transmitted to the central monitoring room using a specific communication protocol. Therefore, many sensors and control devices can be accessed from outside by connecting to a system in the central monitoring room or via a computer in the central monitoring room. Attackers can take over control systems and gather information without the risk of physical intrusion. In order to avoid such vulnerabilities, it is necessary to introduce a defense method into the system, but it is difficult to introduce a system used in the information system due to the characteristics of the control system. We will examine the defense method considering the characteristics of the control system. In this paper, we focus on communications performed between control devices and sensors, and consider a white listing protection method that defines communications that are transferred by network switches. In particular, an object of the present invention is to protect against an attack due to connection of an unauthorized device and an attack for performing unauthorized communication from an authorized devices. In addition, in generating a white list, we discuss functions necessary to reduce the generation cost and management cost.

Abstract: This paper focuses on a day-ahead scheduling problem on power generation of thermal power plants and charge/discharge (C/D) of battery energy storage systems based on the information of the interval prediction of photovoltaic (PV) /demand power. Our purpose is to obtain an exact range of each optimal operation schedule for any possible PV/demand profiles of the interval prediction. If the solution is monotonically increasing or decreasing with respect to the parameter, we can easily find the exact range of the solution in a finite number of trials. In order to obtain the exact range, it is important to find out what problem possesses monotonicity. In previous work, we have shown that monotonicity is preserved in various power system settings. However, it is not clear whether monotonicity is preserved for the problem considering ramp limit of the thermal power plant. Thus, we investigate whether monotonicity is preserved for this problem by using numerical simulation.

Abstract: In our previous paper, we proposed a stable process approach to model dynamics under heavy-tailed noise. In this framework, stochastic linearization is a powerful tool to evaluate the systems' stationary fluctuation. In this paper, we give a method to tighten the error bound of the linearization by means of scaling.

Abstract: In real-world social infrastructures, reliable controllers such as load-frequency control for power systems are already implemented and work well. To further improve the control performance in a reliable manner, bi-layered control with inheriting the exiting controller is proposed: the existing controller generates the reference control signal in the upperlayer, and multiple sub-controllers individually coordinate the reference in the lower-layer to actuate the infrastructure system. The coordination is characterized by designable parameters that represent the degree of the interlayer connection. Then, the learning strategy of the parameter with guaranteeing the safety of the overall system is proposed.

Abstract: Recent years, it is expected that the penetration of renewable energy enables to save the fossil fuel and prevent global warming. However, the power generation output depends on the surrounding environment, and the balancing of power demand/supply is a key problem for the introduction of a large amount of renewable energy. In this paper, we focus on a design method of H2 type preview load frequency control (LFC) and evaluate the achievable performance from the viewpoint of prediction length and information accuracy.

Abstract: In this paper, we deal with a realization problem of cyber physical systems. Cyber physical systems are known to include many heterogeneous dynamical modules such as physical systems, control rules, or optimization algorithms. The connections between modules, which can be different kind of subsystems, need ``transformation of signals'' between physical quantities and information signals. In the realization of such transformation, we should care about what kind of mechanism is possible or not for its purpose. For example, the passivity based methodology to connect subsystems is convenient for guaranteeing the stability of the total systems, however the problem of the physical realization of the feedback connection emerges. From above discussion, in this paper, we focus on our previously proposed hierarchical control and optimization of power networks based on passivity methodology and discuss a problem what structures are physically realizable.
