title: MATLAB Simulation of Production Machines Failure - MTBF & MTTR
body: <p>I want to model production machines' failure in terms of MTBF(mean time between failure) and MTTR(mean time to repair), with exponential distribution. </p>
  
  <p>Actually i am modelling a Discrete Event Simulatin (DEV/DEVS) problem. The problem is concerned with FMS(flexible manufacturing system). It involves six unreliable (likely to fail) machines which can fail during operation. </p>
  
  <ol>
  <li>I want to know how to model unreliable machines in terms of MTBF &amp; MTTR using exponential distribution. </li>
  <li>Also, I want to study the effect of varying MTBF and MTTR values on the problem. e.g. Distribution used: Exponential;MTBF:400,600.....;MTTR:25,50...</li>
