  1. 1. Our Project Title On: Effect of work study & time study on production and quality. Southeast University
  2. 2. Name : MAZADUL HASAN SHESHIR ID: 2010000400008 Batch: 13th Batch (Session 2009-2013) Department: Wet Processing Technology Email: mazadulhasan@yahoo.com Blog: www. Textilelab.blogspot.com Southeast University Department of Textile Engineering PREPARED BY ©right
  3. 3. Objectives of project work: To implement of work study charts to obtain maximum utilization of the resources( Man, Machine & Materials) and to optimize workplace by changing. The plant layout & workstation, using the process charts. Southeast University
  4. 4. Role of industrial engineering department in apparel industry: Importance of industrial engineering (IE) tools that can be used to improve upon the productivity of their factories and thus enhance the profits. Very few companies have been operating with a full fledged industrial engineering department and even those which boast of as an industrial engineering department(IED) in their factories are not allowing freedom and scope to function to its full capabilities. The role of IED is important for the garments industry for the following two reasons: It’s highly labor –intensive industry.  Effective planning is emerging as one of the key factors for the garments manufacturing industry. Southeast University
  5. 5. Garments manufacturing diagram: Fabric from stores Cutting section Sewing section Finishing section Finished garments to warehouse Southeast University
  6. 6. Topics covered during the project work: • Plant layout & workstation design. • work study & time study concepts on production and quality. Southeast University
  7. 7. Workstation Design: Workstation Design are described below- 1. Space requirements. 2. Consideration of the space requirement for the movement of material handling equipment. 3. Easy access to safety stops in case of emergency. 4. Easy access to machine for inspection and lubrication, maintenance and repair. 5. Space between one machine to another machine. 6. Appropriate ventilation, lighting & safety. Southeast University

  10. 10. Work Study Method Study Work Measurement What is work study?  Work study is mainly concerned with the examination of human work. There are two parts of work study: Southeast University
  11. 11. • To eliminate wastage of time and labor. • To reduce fatigue and boredom of work by avoiding unnecessary movements. • To find a best way of doing a job. • To have more utilization of materials, machines and workers. • To improve the design of work place layout. • To standardize the method, obtained after conducting the motion study. • To train the individual operator in its practice as per standardized methods. Why work study? Southeast University
  12. 12. • Set target • Manpower allocation • Calculate efficiency • Production planning and control • Determine cost • Incentive schemes Why Work Measurement is Important? Southeast University
  13. 13. Work Measurement Techniques  Time Study: Directly observing an operator.  Pre-Determined Motion Time Study System: Analyzing the motions used to carry out the activity.  Analysis of Past Records: Using previous records/ Studies available in the factory. Southeast University
  14. 14. Time Study To determine the time it should take for a qualified worker to perform a specific task using a specified method by directly observing an operator. Southeast University
  15. 15. Time Study Sheet of IE Department: Southeast University
  16. 16. Observed time X 1. Compute the basic time Basic Time = 2. Compute the standard minute value SMV = Basic Time + Allowance Standard rating How it Works? Observed rating Southeast University
  17. 17. GSD layout of IE: Southeast University
  18. 18. SL Operation Observed time Standard time 1 Seam right shoulder 15” 10” 2 Bind neck 16” 10” 3 Seam left shoulder 14” 11” 4 Bind sleeve openings 14” 12” 5 Seam sleeves 14” 12” 6 Attach sleeves 36” 30” 7 Cut & fold label 7” 4” 8 Attach label 16” 12” 9 Bartack shoulder & neck 10” 6” 10 Hem bottom 16” 12” Total time 158” 119” Practically process following in the sewing floor: List of processes to produce T-shirts: Southeast University
  19. 19. SI Operator Process Observed time Rating Basic time Allowance time Standard time 1 Rahima Stay sewing 9” 80% 7.2” 20% 8.6” 2 Nazma Collar fitting 3” 75% 2.25” 20% 2.7” 3 Moyna Collar sewing 30’ 85% 25.5” 20% 30.6” Time measurement table: Southeast University
  20. 20. For this process operation is 2, but making time taking around 10 min. seam joining uneven, seam, broken stitch, puckering needle hole and down grade quality etc defects are coming more which clearly indicate that garment piece handling by the operator are not proper, they need to trained how to handle the fabric or the proper method of stitching the garment. Practically process following in the sewing floor: Southeast University
  21. 21. Southeast University
  22. 22. In this case, we need to follow PDCA process improvement chart which can give us a solution. PDCA Figure : The Shewhart Cycle is a fundamental idea for continuous process improvement. Southeast University
  23. 23. Benefits of TQM: The benefits of TQM can be classified into the following two categories: 1. Customer satisfaction oriented benefits. 2. Economic improvements oriented benefits. 1. Customer satisfaction oriented benefits: The benefits under this category are listed below: (a) Improvement in product quality. (b) Improvement in product design. (c) Improvement in production flow. (d) Improvement in employee morale and quality consciousness. (e) Improvement of product service. (f) Improvement in market place acceptance. 2. Economic improvements oriented benefits: The benefits under this category are as follows: (a) Reductions in operating costs. (b) Reductions in operating losses. (c) Reductions in field service costs. (d) Reductions in liability exposure.
  24. 24. Time Study Exercise Process Name = Side Seam Observed Time = 35.27 Sec Observed Rating = 92% Allowance = 25% Basic Time = (35.27 X 0.92) Sec = 32.45 Sec SMV = 32.45 + (32.45 X 0.25) Sec = 40.56 Sec Capacity = (3600 ÷ 40.56) Pcs/ Hour = 88 Pcs/ Hour
  25. 25. Some suggestions:
  26. 26. Existing Proposed  Operation are not arranged in sequence,  Intersection of material flows occur.  Material movement is more.  Material handling is more.  Operation are arranged in sequence,  Intersection of material flows avoided.  Material movement is minimized.  Material handling is minimized. Southeast University
  27. 27. Conclusion  WITH THE APPLICATION OF WORK STUDY CHARTS IN APPAREL MANUFACTURING, THE EFFECTIVE UTILIZATION OF RESOURCES ( MAN, MATERIAL & MACHINES) CAN BE ACHIEVED.  THE COST INVOLVED IN USING THESE CHARTS ARE VERY MINIMUM AND A SOLUTION CAN BE DERIVED IN A SHORT PERIOD OF TIME. Southeast University
