在信息技术迅速发展的背景下,利用计算机技术进行审计证据的处理与评价具有重要意义。D-S证据理论能够进行不确定性推理,可以用于处理审计证据判断的不确定性,因此开发基于D-S证据理论的审计证据评价系统是可行的。在阐述D-S证据理论基本原理的基础上,分析审计证据评价系统的功能需求,设计系统的功能结构,阐述审计证据合成模块的程序流程,并基于B/S结构实现该软件系统。该系统能够提高审计证据的证明效力,降低审计风险。
Under the background of the rapid development of information technology,it is of great significance to manage and evaluate audit evidence using computer technology.D-S evidence theory is an effective means to make uncertainty reasoning,thus can be used to deal with uncertainty in audit evidence.Consequently it is practical to develop audit evidence evaluation system based on D-S theory.The elementary principle of D-S theory is firstly described.Then the functional requirements are analyzed and the functional structure is designed.Finally the flow of the evidence fusion module is explained and the evaluation system is implemented with B/S structure.The use of this system can enhance the proof performance of audit evidence and decrease the audit risk.
