One of the most effective tools of Industrial Engineering is capacity study & analysis of a sewing line to increase or improve productivity. By using method, time, capacity, and production study, it is possible to improve productivity while reducing wastage. Two important attributes have been considered, one is possible standard method for each process, and another is considerable time. Time study took to record the actual individual capacity of each worker. I have recorded the time to make each process for each worker to find out the optimum number of operator and helper, type of machines, and individual capacity. To find out the (standard minute value) S.M.V, process wise capacity has been calculated, in addition to that I have calculated the target, capacity, manpower, line graph, labor productivity and line efficiency. Line has been balanced considering the bottleneck and balancing process where the balancing process has shared the excess time after the production in the bottleneck process. After applying all those processes, I have compared before & after situation of balancing the line, labor productivity and line efficiency. Finally proposed production layout has been modeled and ensures a better productivity.
