Abstract: Sugar plant is complex unit, which comprises systems such as feeding, juice extraction, steam generation, refining, crystallisation, etc. To maintain operating unit efficiently, it is necessary to maintain the critical parts of the system. Feeding system is one of the major subsystems of sugar plant. In the present work, performance modelling and behaviour analysis of feeding system of sugar plant have been highlighted. The behaviour analysis of feeding system has been done with the help of performance modelling using probabilistic approach. After drawing the transition diagram of feeding system, the differential equations have been developed. The solution of the equations shows various performance levels for different combinations of failure and repair times of all the subsystems of feeding system. Based on various performance values obtained in availability matrices and plots of failure times/repair times of various subsystems, performance of each subsystem was analysed and maintenance decisions were made for all the subsystems of feeding system.
