The Optimized Model Of Money Laundering Route Based On Multi-objective Programming And Its Arithmetic Study

With the current economic globalization and the rapid development of information technology,the phenomena of economic crimes committed by civil servant are growing increasingly.Meanwhile,the illicit assets amassed by some criminals in the upstream economic criminal activities have been gradually exposed to the public under the high pressure of Chinese government's anti-corruption.For concealing their corpus delicate,these criminals make the way of disposing their illegal asset more hidden and the whole process more ripe and intelligent.Their diverted disposals to the illegal assets not only damage the security of national financial system and the reputation of Chinese government but also bring much more difficulty to our law enforcement and supervision departments,leading to the cost increase of detection.Therefore it is necessary for us to study the path of the transfer of illegal asset with money laundering by the civil servants.The optimized laundering of the illegal civil servant is a problem of the multi-objective and multi-stage optimized choices.At present,the study on the optimized route of the multiple stages and objectives has drawn researcher's wide attention and has made great achievements.But the study concerning the civil servant' money laundering is less involved.This paper is aimed at the systematic study on the optimized money laundering by the civil servant by using multi-objective optimization theory.The main points are summarized as follows:(1)Analyze comprehensively the civil servants laundering progress,and the laundering objectives on different stages.Build the multi-objective programming model of the basic laundering network optimization for achieving the goals of maximizing thequantity,minimizing the risk and shortening the time of money laundering simultaneously.Finally,put forward the algorithm of the basic model by utilizing the improved table dispatching method and proof whether the algorithm is practicable or not through the examples.(2)According to the civil servants' analyses of cost and profit in their real lives,the paper constructs the laundering networks of multi-frequency transfer account on the basis of the basic laundering network;The paper extends the network model of the basic multi-objective laundering on the basis of the multi-frequency cash flows between nodes,and construct the optimization model of multi-frequency and multi-objective laundering network route;Lastly,the paper improves and optimizes the algorithm of the basic model,which is proved to be practicable through the examples.(3)The paper popularizes the laundering network in one stage to multi-stage by utilizing dynamic programming thought and expand multi-frequency and multi-objective model to the optimization model of the money laundering network route of the multiple stages and objectives;Secondly,the paper uses expected utility theory to study the risk appetite of the illegal civil servants,and then puts forward five different choices about laundering objectives they would make in different time periods and with their different appetites.Finally,the paper presents the specific algorithm for the choices of different laundering objectives in accordance with the multiple dynamic programming and max-flow theory.It is proved to be practicable through the examples.(4)The paper proposes the measures for preventing the civil servants from money laundering in the aspects of naked officials flight,large trading,criminal psychologic progress of laundering,and trading hour,etc.aimed at the different choices of the laundering objectives for the civil servants with different preferences under the time pressure.
