    摘要:

    提出公安宣传资源配置的最优化模型,对公安宣传的效果进行量化评判,解决在固定资源的条件下最大化公安宣传效果,采用诈骗案件数据进行最优化模型验证。定义宣传成本和宣传对象,定义模型最优化目标为最小化社会被害损失,通过不同宣传对象的平均损失、被害可能性推导最优化模型。利用贝叶斯公式转化特定人群受到伤害的统计信息,简化目标函数,构造拉格朗日函数。计算权重矩阵和参数向量,利用KTT条件或Matlab求解非线性最优化方程。利用收视数据和D市被害人年龄及其被诈骗金额数据,根据客观数据得出在不同类型媒介需要投入的比例,资源配置的最优化模型可操作性强,得出结论清晰明确,可直接指导实践工作。

    Abstract:

    This research proposes the optimisation model of propaganda resource allocation in the field of public security. This model can quantitatively evaluate the effect of public security propaganda. It solves the problem of maximising the effect of public security propaganda in the condition of fixed resources, and the optimisation model was verified by using the data of fraud cases. Define the propaganda cost and the propaganda objects, and set minimising the loss of social victimisation as the optimisation objective of the model. The optimisation model was derived from the average loss and the possibility of victimisation of different propaganda objects. The Bayesian formula is used to transform the statistical information of a specific population. Simplify the objective function, and construct the Lagrange function. Calculate the weight matrix and parameter vector, utilise KTT condition or MATLAB to solve the nonlinear optimization equation. By using the audience rating data and the data of the age of the victims and the amount of the victims cheated in D city, the proportion of the investment needed in different types of media was obtained according to the objective data, and the propaganda resource allocation scheme which could directly guide the practice was obtained. The optimisation model of resource allocation has strong operability and the conclusions drawn from this model are precise and clear. This model is based on objective data with strong operability, which is simple to apply, convenient to calculate.
