SMV = Basic time + (Basic time * Allowance)

Basic time = Observed time * Rating

Observed time = Total Cycle time / No of cycle

Rating = (Observed Rating * Standard rating) / Standard rating

Efficiency = (Earn minute * Available minute) * 100


Earn minute = No of Pc’s (Production) * Garments SMV







Available minute = Work hour * Manpower



Organization Efficiency = (Basic pitch time / Bottle neck time) * 100



Basic Pitch time (BPT) = Total Garments SMV / Total Manpower



UCL = Basic pitch time/Organization Efficiency or {UCL is calculated by adding 10% of BPT}


LCL = 2 * Basic pitch time – UCL or {UCL is calculated by minus10% of BPT}



Performance = {Earn minute * (Available minute – Off standard time)} * 100


Balancing loss = {AML – (TML/AML)} * 100



TML = Operational SMV / BPT



Capacity = 60 / Capacity time in minute




Line target = (Work hour/SMV) * Present operator * Organizational efficiency


Factory capacity = (Work hour / SMV) * Total worker * Working day * Efficiency


CPM = (Total over head cost of the month / No of SMV earners * Work minutes)*Efficiency
