Availability Analysis of Carded Sliver Yarn Production System Using Numerical Technique

Abstract

This research work focuses on analysis of Long Term Availability (LTA) And Transient Availability (TA) of the complex system namely Carded Sliver yarn Production System of a Textile Industry with the application of Markov Method (MM). The mathematical model for the system concerned has been developed on the basis of actual working conditions. The model developed is being solved using numerical method namely Runge-Kutta (RK) to compute TA i.e. Time dependent. Further LTA has been computed by applying normalizing condition, and recursive method. On the basis of LTA and TA analysis the most critical subsystem has been identified. Here, component D i.e. Draw Frame is most critical component in the present case. Further, repair priorities have been proposed on the basis of impact of Repair Rate (RR) on LTA and TA of the system chosen. The proposed repair priority for component D, B and C are I, II and III respectively.
