Designing of integrated system-dynamics models for an oil company
This paper presents a new approach to designing integrated simulation models for large corporations. This approach is based on the use of system-dynamics methods for implementing models of segments of the vertically integrated company taking into account the available direct and feedback links. All models have been designed with the help of power simulation tool - Powersim Studio. In addition, the designed simulation system has been integrated with created genetic algorithm and the corporate data warehouse.

This paper presents the simulation tool for study future ATM systems, based on advanced CNS capabilities. Research Stand for hardware-in-the-loop and human-in-the-loop simulation of Air Traffic Management System is the simulation tool, which includes on-board and ground-based components of the air traffic management system. Due to wide range of integrated components the Stand allows studying advanced concepts and technologies of the whole air traffic management system. The Stand allows running simulation in fast-time and real-time modes. Fast time simulation is applied to the long-term experiments. During this simulation all components work in automatic mode. Real-time human-in-the-loop simulation runs to demonstrate functional interaction between ATM components. The main goals of the researches, conducted on the stand, are: • approbation of pilot and air traffic controller interaction; • approbation of new cockpit and ATC system interfaces; • approbation of new airborne functions; • assessment of changes in air traffic characteristics in case of using CNS capabilities .
In this work is presented a new approach to the designing of intelligent systems of the control of the shareholder value for the vertical-integrated Financial Corporation (VIFK). Developed system based on using of system-dynamics methods for the simulation of the synergic interaction between different business directions of VIFK for the target of shareholder value maximization. Note, the described system has been successfully introduced in biggest Russian banking groups and it is used for the preparing of strategic decisions.
I. The simulation and research into advanced airborne CNS procedures was conducted by the Research Stand for Hardware-in-the-Loop Simulation of Air Traffic Control Systems (KIS UVD) in 2013–2014. II. As part of the research, the following CNS procedures were reviewed: • ITP (In-Trail Procedure) • FIM (Flight-Deck Interval Management) • ACM (Airborne Conflict Management). III. Real-time simulation was conducted with the participation of ATC workstation operator, operator of the advanced cockpit DKS IMA simulator and pilot workstation operator. IV. The research into CNS procedures was conducted using fast-time simulation in automatic mode without operator's participation. V. As part of the work • the cooperation of pilot and ATC during advanced CNS procedures was approbated • the interfaces of CNS procedures for pilot and ATC were tested • performance approbation of CNS procedures in high air traffic conditions with the impact of random factors was held • the quantity characteristics of changes in performance caused by using new CNS procedures were calculated • CNS procedures were compared with standard procedures VI. The results show • Improved performance and prospects using new CNS procedures • KIS UVD stand practicability for simulation and research of airborne and ATC procedures • Need for future research of CNS procedures VII. The future research trends are: • The research of airborne procedures in different air traffic intensity and in conditions where one part of aircrafts is equipped with ADS-B-, ITP-, FIM-, ACM avionics and another part is not equipped • The research of FIM procedure on STAR • The simulation and research of other ADS-B-based procedures (ASIA, SURF) • The research into airborne procedures, connected with weather hazard avoidance • The research into airborne procedures using the real air traffic.
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.
In the article are considered various approaches to the problem of the choice of investments' level of the company: a number of the factors which influence the investment activity of the company is revealed; influence of return on investments (ROI) on the investment policy is analysed. The review of economic researches on determinants of investment policy of the companies is studied, various approaches to calculation of ROI are considered. The basic steps and results of the empirical research based on the russian companies' data are presented.
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.
