【摘要】 为应对食品安全系统的复杂性,食品安全危机管理系统集成专家系统、危害分析和关键控制点、自适应调控系统,从而具备多领域知识集成、自我修正偏差能力,并体现管理者的政策成本优化目标。在被控对象的结构分析基础上,引入管理者的成本优化目标,对食品安全政策进行数值模拟。结果表明,尽管离目标较远的控制政策设定具有较低的单位成本,但难以在短期内有效地影响目标变量,长期政策与短期政策配合使用能够起到优化政策总成本的作用。更多还原

【Abstract】 To deal with the complexity of food safety system,the management system should integrate the expert system,hazard analysis critical control point,and adaptive control system.This system can integrate knowledge of multiple areas,be self-adjustable,and optimize the cost of policy mix.We simulate the food safety policies.Although several longterm policies have lower unit cost,they take more time to affect target variable than the short-term policy,which leads to the result that the specified time and achievable minimum cost of policy mix may have areverse relation.更多还原
