System behavior analysis in the urea fertilizer industry

Abstract

This paper models and analyses a urea plant having subsystems of different operational nature for system parameters using Regenerative Point Graphical Technique (RPGT). A common cause failure is also considered in modeling. Problem is formulated and solved for constant failure/repair rates for each subsystem. A state diagram of the system depicting the transition rates is drawn and expressions for path probabilities mean sojourn times are derived. Analytical discussion is carried out by tables and graphs. Behavioral inferences have been drawn which may useful to concerned industrial personals.
