针对当前燃气轮机关键部件维护及维修管理中由人工统计计算维修间隔，造成费时耗力、准确性低的问题，提出燃气轮机视情维修决策模型，结合燃气轮机已经运行时段的历史运行数据和待预测时段的实际运行计划，对部件维修周期进行预测。提出等效服务系数的概念，根据2个时段的等效服务系数，建立4种预测模型，并利用 ASP.NET 技术，实现了基于 B/S 架构的燃气轮机视情维修决策系统。该系统可在线自动计算燃气轮机相关部件的使用寿命，并决策计算维修周期，为科学制定维修计划和进行备件信息管理工作奠定基础。该决策系统已应用于工程实际，取得了良好的效果。

Aiming at time-consuming, labor-intensive and low-accurate manual statistical calculation in key part maintenance and maintenance management of gas turbines, this paper proposes a condition-based main-tenance decision-making model for gas turbine which predicts component maintenance cycle in combination with historical operation data of gas turbine in the past running period and actual operation plans in the pre-dictive period. The concept of equivalent service factor is proposed. Based on whether the equivalent service factors of two periods are equal, four decision-making models are established, and by using ASP.NET tech-nology, a condition-based maintenance decision-making system based on B/S structure for gas turbine is de-veloped. The system can calculate service life of relevant components of gas turbine automatically online and determine and calculate maintenance cycle to lay a foundation for making scientific and feasible maintenance plan and conducting information management of spare parts. Finally, the decision-making system is put into engineering practice, from which favorable application effect was achieved.
