The present paper discusses the operational behaviour of feeding system (i.e. the main functionary part) of the sugar plant. The system consist of three subsystems (having a number of units with different configurations) i.e. the crushing system, bagasse carrying system and the steam generation system. The units of crushing and bagasse system are in series while the units of Boilers and steam generation system are in parallel. Taking constant failure or general repair rates for each subsystem, the steady state availability are evaluated. Availability tables for various failure and repair rates with graphs are given followed by a parameter.
