This paper aims to outline a proposed knowledge base system (KBS) for the assessment of corrosive damage on metallic pipe conduits. KBS is developed by using two information sources available for assessing the corrosive damage of pipes which are mainly: expert knowledge and field data. In our knowledge, it's a new method that assists the engineer in his task for assessing the degree of damage on metallic pipes, yielding therefore to a rational evaluation of the corrosive damage (hence the ECOR system) on metallic structures of pipeline, and permits to assign the damage degree on the structure qualitatively while using a ladder of indications representing the severity of each damage type (pitting, crater, weight loss and crack), regarding the priority of either repairing or replacing the metal piece. Furthermore, the analytic hierarchy process is implemented overall the system to determine whether the damage severity requires the engineer intervention in a systematic and rational way.
本文旨在概述一个用于评估金属管道腐蚀损伤的知识库系统（KBS）。KBS通过利用两种可用于评估管道腐蚀损伤的信息源来开发，主要是：专家知识和现场数据。据我们所知，这是一种新方法，可协助工程师评估金属管道的损伤程度，从而对管道金属结构的腐蚀损伤进行合理评估（即ECOR系统），并在使用代表每种损伤类型（点蚀、坑洼、失重和裂纹）严重程度的指示阶梯时，定性地确定结构上的损伤程度，同时考虑修复或更换金属部件的优先级。此外，在整个系统中实施层次分析法，以系统、合理的方式确定损伤严重程度是否需要工程师干预。
