The conception and design of Resource Constrained Embedded Systems (RCES) is an inherently complex endeavor. Non-functional requirements from security and dependability are exacerbate this complexity. Model-Driven Engineering (MDE) is a promising approach for the design of trusted systems, as it bridges the gap between design issues and implementation concerns. The purpose of process models is to document and communicate processes, as well as reuse them. Thus, processes can be better taught and executed. However, most useful metamodels are activity-oriented, and the required concepts of safety lifecycle, such as validation, cannot be easily modeled. In this paper, the authors propose a safety-oriented process metamodel that extends exiting framework to support all safety control requirements. A new safety lifecycle development processes technique has been built to ease its use in a building process of system/ software applications with safety support. As a proof of concept, the feasibility of the approach has been evaluated with an example. The example is an engineering process for building industry control systems with safety requirements for software and hardware resources. A prototype implementation of the approach is provided and applied to the example of industry control systems in the railway domain.

Operator Control

Much has been learned in the past ten years about the dynamic performance of the human operator in control tasks primarily involving visual stimuli. In many human activities, however, sight is complemented or superseded by other senses. One important sense modality whose dynamic use is as yet poorly understood is touch. This paper describes an experimental technique for investigating human operator dynamics in tasks where tactile stimulus information is of primary importance; some exemplary results are presented.

The article analyzes the current regulatory framework for proof of safety, quality assurance, and confi rmation of the conformity of microprocessor-based railway automation and remote control systems in the EAEU. CENELEC standards are briefl y discussed. A brief overview is provided as regards measures to ensure the required level of safety of microprocessor-based railway automation and remote control systems from the point of view of quality management of development, safety management, and confi rmation of the proper functioning of microprocessor systems. The practice of confi rming the railway transport automated process control systems comply with standards in the form of a declaration of conformity per TR CU 003/2011 has been analyzed. It is concluded that there is a need to develop a regulatory framework to ensure regulated analysis and assessment of railway automation and remote control systems following the requirements of functional safety, as well as further development of standardization documents to regulate methods for assessing functional safety.

Purpose: Analysis and determination of the main modern international safety requirements that must be met in the design, development and operation of industrial equipment management systems, as well as confirmation of the need for further improvement of the domestic regulatory framework in this area.Performed analysis of the requirements of modern international standards (IEC 62061, IEC 61508) on the safety of electrical, electronic and programmable electronic control systems for industrial equipment and the existing sequence of protection against hazards; the main features of the architecture of such control systems are identified and algorithms for determining the main indicators of their functional safety (PL; SIL PL; PFHd) and an algorithm for ensuring the required level of security depending on the parameters of existing risks are provided. The analysis of the features of functioning and application of modern international safety standards, which must be observed in the design, development and operation of industrial equipment management systems convincingly confirms the relevance and need for further improvement of domestic regulations in this area. The main parameters (indicators) of safety of functioning of electric, electronic and programmable electronic control systems of industrial equipment are determined. Relevant recommendations are provided on the main aspects of their application and implementation according to IEC 62061 and IEC 61508.The development and implementation of relevant national standards based on IEC 62061 and IEC 61508 should accelerate the further development of technical progress in the field of industrial safety. Confirmed relevance and importance of the need to develop relevant national standards based on IEC 62061 and IEC 61508.

Security Standards

The required level of safety of machines and mechanisms is achieved through the use of appropriate safety management systems for industrial equipment, including programmable electronic ones. Such systems usually include a variety of security devices for managing industrial equipment settings. Since electronic control systems are currently considered the most promising control systems in this area, the study of the security parameters of their application support determines the relevance of this study. This study analyses the main requirements of IEC 61508 and IEC 62061 standards for compliance with modern safety requirements of embedded and applied software for electronic control systems of machines and mechanisms. This study proposes an algorithm for step-by-step implementation of software for electronic machine control systems in accordance with basic security standards for both built-in and application software. Testing has been determined as the main method of verification of application software. Based on the results of the analysis, it was found that the specification of security requirements, both built-in and application software, should highlight the necessary characteristics of each subsystem, providing information that allows choosing the equipment that meets existing security requirements. Relevant recommendations are given on the specifics of practical application of these standards.
