This paper discusses the decision support system for the chipping unit of a paper plant. The chipping unit consists of six subsystems arranged in series and parallel configurations. The decision support system for the chipping unit was developed with the help of a mathematical formulation based on Markov Birth-Death process using a probabilistic approach. For this purpose, first differential equations were generated. These equations were then solved using normalizing condition so as to determine the steady-state availability of the chipping unit. After that, decision matrices were developed which provide various availability levels for different combinations of failure and repair rates for all subsystems. The model developed helps in the operations and quantitative management of various maintenance decisions and actions. The results of this paper are, therefore, beneficial in deciding the relative repair priorities of the various subsystems of the chipping unit. [ABSTRACT FROM AUTHOR]
