چکیده

Money laundering is a complex and dynamic process, which conceals the sources of money.Insurance companies are faced with the challenge of money laundering. It encounters insurancecompanies to legal, operational and reputational risks. Previous studies in insurance investigate the fraudin insurance, whereas money laundering as a crucial phenomenon in insurance is neglected; therefore, we explore for the first time the money laundering in insurance and proposed an efficient statistical method to detect it. In this paper, we propose a useful strategy namely stratified sampling, which distributed allsamples to different strata subject to minimizing the variance of overall amount of money laundered dueto money laundering activities. To solve this objective function we develop an efficient particle swarm optimization (PSO) which is combined with the neighborhood search (NS) algorithm. Then for anumerical example, we run this metaheuristic algorithm and compare the results respect to objectivevalue and CPU time with genetic algorithm and traditional PSO approach. These comparisons imply that PSO algorithm, which is combined with NS, performs better than other methods for this problem; also, results show that the near optimum number of strata is 600. In other word, we divide the insured into 600 groups and survey these samples instead of survey all insured

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
