A Maintainability Prediction Method Considering Environmental Impacts and Cost
摘要
Maintainability prediction is one kind of primary maintainability action.Design deficiency would be found through predicting maintainability parameters under certain conditions.Now a main-tainability prediction method that mainly considers maintenance time or maintenance man-hour is a kind of prediction method with a single index.With increasing product complexity and peoples environ-mental consciousness, more attention is paid to environment impacts and maintenance cost or resource consumption in the maintenance process.It is necessary for a maintainability prediction method that can predict maintenance cost and maintenance environmental impacts .A new maintainability predic-tion method is presented in this paper based on analyzing existing maintainability prediction methods.The method is MABTCE(maintenance activity based timing/costing/environment impact assessment) and can pridict maintenance time,maintenance costing and maintenance environmental impacts and then improve maintainability design with prediction results.
