Informative and Formal Description of Structure Dynamics Control Task of Cyber-Physical Systems
The authors propose the informative and formal description of Structure Dynamics Control Task of Cyber-physical Systems (CPS). The main advantage of proposed poly-model multicriterion approach for the structure dynamics control tasks decision is that, in comparison with previously developed control models oriented on CPS simulation, proposed models allow to increase the efﬁ ciency, validity and, in general, the quality of the SD control CPS due to the original combination of their static and dynamic models
System design where cyber-physical applications are securely coordinated from the cloud may simplify the development process. However, all private data are then pushed to these remote “swamps,” and human users lose actual control as compared to when the applications are executed directly on their devices. At the same time, computing at the network edge is still lacking support for such straightforward multidevice development, which is essential for a wide range of dynamic cyber-physical services. This article proposes a novel programming model as well as contributes the associated secure-connectivity framework for leveraging safe coordinated device proximity as an additional degree of freedom between the remote cloud and the safety-critical network edge, especially under uncertain environment constraints. This article is part of a special issue on Software Safety and Security Risk Mitigation in Cyber-physical Systems.
Cyber-physical systems (CPS) are widely used due to the “Industry 4.0” concept development within which digital enterprise transformation and the use of new management techniques based on the Internet of Things (IoT) and Big Data analytics assume primary importance. In general, CPS is a class of information systems whose computational elements are integrated into physical processes and objects; such systems can interact with each other using Internet protocols. The growing number of situations requiring CPS implementation determines the necessity of CPS design that takes into account the specific factors of a subject area. The CPS structure includes hardware and software which in many ways affect the security and cost of a technical solution, the convenience of user interaction with the system. A significant CPS programs feature is ensuring long-term performance and high sustainability which is largely complicated by the lack of unified solutions (templates) for CPS software design. This obstacle affects the realization of other software requirements as well. The purpose of the study is to identify ways to optimize the cost/quality ratio of the CPS software being designed that uses the technologies of the Internet of Things and present findings in the form of recommendations suitable for further use. One of the methods that realize complex organizational and technical solutions evaluation is Value Engineering (VE). CPS software functions have been identified and the anticipated system software structure has been determined. The results of applying the VE method to CPS software have been reflected and the conclusions considering the practical significance of the study have been drawn. The analysis has been carried out within the priority area of scientific development established in the National research university Higher school of economics (Perm) – “Research on control methods in cyber-physical systems”.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
Many electronic devices operate in a cyclic mode. This should be considered when forecastingreliability indicators at the design stage.The accuracy of the prediction and the planning for the event to ensure reliability depends on correctness of valuation and accounting greatest possiblenumber of factors. That in turn will affect the overall progress of the design and, in the end,result in the quality and competitiveness of products
