基于遗传神经网络的科研项目经费预算方法

Scientific Research Project Budget Estimate Method Based on GA-BP Neural Network

针对科研经费预算准确性与实用性无法兼顾的难题,提出基于遗传神经网络的科研项目经费预算方法.分析了科研项目经费构成及影响预算的关键因素,建立了影响因素的量化表达式,将量化结果作为输入,项目经费预算结果作为输出,利用遗传算法优化BP(Back Propagation)神经网络的权值和阈值,通过训练遗传神经网络预测模型建立输入与输出之间的非线性关系.运用预算实例对预测方法进行了有效性验证.仿真结果表明该方法有较高的预测准确性.

An analysis was made of the component and influencing factors of research budget.Then,a research budget estimate model based on Genetic Algorithm-Back Propagation （GA-BP） neural network was built,of which,GA was used to optimize the weights and thresholds of BP neural network.A nonlinear expression between influencing factors （input） and the budget （output） was created.The effectiveness of the method was tested.Test results show the model based on GA-BP neural network is reliable and accurate.
