This paper is devoted to the analysis and computation of overall as well as various subsystem availabilities of a urea fertilizer plant. Based on the analysis, appropriate maintenance strategies for different situations have been developed. Using Lagrange's multiplier technique the cost of maintenance and manpower is analysed. By minimizing the maintenance cost allocation to various subsystems, the optimum repair policy is determined.
