In type’s production management techniques, operations management is one of the most powerful techniques for production floor management decision making. The application of the techniques is conducive to solve many complex problems associated with assembly controlling, scheduling which otherwise are more difficult to solve. Assembly Line Balancing (ALB) technique is one of the most efficient method of operations management for solving workload related problems and increasing line efficiency. A case study has been carried out at Envoy Textile Limited in Savar about workload allocation and bottleneck related problem. The experimental result shows significant improvement in productivity and line efficiency as compared to the existing system.
