2003 in St.Petersburg, IPME, RAS), [115–118] and the papers [2,4,7,14,15,42,54,69] In the area of economy and finance, there are the following applications of the risk LP-theory: Credit risks; Analysis of bank credit activity; Security portfolio risk; Risk in problems of efficiency; Modelling of bribes; Swindle risk of managers; Fraud risk with investments; Management of state and development of the company (bank) by risk criterion; Non-success risk in struggle of companies for profitable orders; Non-success risk at financing building projects with reservation; Estimation and management of bank personnel; Risk of rent business; Risk of loss of quality and market; Risk of insurance; Risk analysis in money and commodity markets (Technical Analysis) In the area of engineering and ecology, there are the following applications of the risk LP-theory: Risk of explosion in a submarine; Risk estimation of car accidents on the crossroads without traffic lights; Non-success risk of debugging and operational tests of complex objects; Risk of the man injury by electrical current in a room; 378 E.D.Solojentsev Safety on the railway; Explosion risk of a artillery warehouse; Accident risk in an intrinsically dangerous room; Drowning risk for a submarine; Risk analysis of the ship power station; Explosion and fire safety of gas and oil transmitting stations; Risk modelling of three-channel system of nuclear station safety; Economic safety of a defense enterprize; Operation safety of the ground-based space structure; Risk insurance at realization of space activity; Analysis of technogenic safety; Safety estimation of the divergence of trajectory of ships; Risk monitoring in functioning systems of the rocket starting complex; Risk modelling and estimation on nuclear-dangerous plants; Risk modelling and analysis in power systems; Safety management of the nuclear reactor; Risk of resource prolongation of worn power equipments The applications list of the non-success risk LP-theory confirms that the risk LP-theory is attractive for engineers and economists The examples of use of the non-success risk LP-models in business showed the efficiency of LP-models in sense of accuracy and robustness, opportunities of risk analysis and risk management The examples of the use of the non-success risk LP-theory in engineering showed the high efficiency concerning opportunities of estimation of failure risk or accident and revealing weaker elements in the system, for which it is necessary to increase reliability by allocating resources in the first place Comparison of features and similarities of the non-success risk LPtheory with other methods of risk estimations and object classifications and also the above review of applications of this theory in economy, engineering and business allow us to speak about creation of the new scientific direction in the theory and practice of risks We name the direction the scenario logic and
