Costing RAM design and test analysis model for production facility

The objective of this paper is to provide a model for effective implementation of costing RAM (reliability, availability and maintainability) management in the design and procurement of production facility. This research proposed a two-stem model of costing RAM design and test for production facility. In Step 1, a static model is proposed to find an initial system configuration to meet the required performance based on system RAM and life cycle cost (LCC) and analyze the trade-off relationships between various RAM factors (reliability and maintainability) and LCC. In Step 2, we developed time and failure truncated models for system reliability test and analysis. For computational purposes, we developed computer programs and have shown the sample results. By the sample test run, the proposed model has shown possibilities to provide a good method to analyze system performance evaluation for both design and operational phase. This model can be applied to a wide variety of systems, not only for costing RAM of the production facilities but also for the other kind of equipment.
