the stochastic models for ship heave motion in irregular sea waves based on white and colored noises are examined. for this purpose the deterministic model transfers to stochastic models by adding different noise terms in force and then these models are solved analytically and numerically. finally an investigation is undertaken to examine the parameter estimation problem of second order stochas...

In this paper, we regard policyholders, insurance companies, and government departments to be an anti-fraud supervision system, explore the of motor vehicle fraud from perspective a tripartite game. Taking into consideration bad reputation records policyholders as state variable, through continuous accumulation in effective time, it creates growth-type warning effect on thus, effectively curbs ...

in this paper, a novel hybrid model based on neural network and game theory is proposed to support the analyzers in oil market. in this model, first the neural network is utilized to learn the oil prices associated with opec production level and usa imports level. then the learned neural network is applied by a game model. finally the nash equilibrium points of the game present the optimum deci...

We develop a political economy model of trade agreements that incorporates contracting costs and uncertainty. The model delivers simple expressions for policy bindings with parameters relating to trade shocks and to political demand shocks. We identified conditions under which the trade volume is positively associated with the payoff of restricting production subsidy/consumption tax. Our model ...
