In This Study We Find Out the Alternate Formula For Production Rate. We Know the Actual Production Rate of from the All 60 Out Comes from We Find Out from the C Programming Computation. But the Computation For Large (More Than 5 Station Un-Paced Production) Un-Paced Production Line Is Difficult Therefore We Make an Arrangement from This Study to Design an Assembly Line Production Who Is Working Efficiently from This Easiest Formula.
