Modul 1 process planning and standard time calculation

1. MODULE 1 Process Planning and Standard Time Calculation

2. Production System Production system is a set of interacting subsystems with the purpose of transforming production inputs into production outputs.

3. Production System

4. Production System Parameter Production Productivity Efficiency Effectiveness Utilitie Quality Capacity

5. MRP II (Manufacturing Resource Planning)

6. Relationship Between MRP and MRP II

7. Just In Time (JIT) Just In Time is a production system or a modern fabrication management system developed by Japanese – American named Taichi Ohno of Toyota motor vehicles companies. JIT is a concept in which the raw materials used for production activity brought from the supplier of the material was right on time needed by the production process, so it will greatly save even eliminate the cost of inventory. The tool that is used in the JIT called Kanban

8. Kanban JIT production system using a flow of information in the form of a Kanban card-shaped or other equipment such as flags, lights, and others

9. 7 types of waste Over production Waiting Transporting Unnecessary process Inventory Unnecessary movement Rejection

10. 5 S

11. Bill Of Material (BOM) BOM (Bill of Material) is a list of the number of components, material and the ingredients

12. Operation Process Chart Operation Process Chart is a chart performs the process of raw material into a product which the operation steps and inspection belongs.

13. OPC The Benefit of OPC: To know the production costs and machine To know raw material spent (efficiency consideration in each step and inspection) A tool for layout and facilities design. A tool to diagnose work method. A tool for work experience

14. OPC sign

15. Standard Time Standard time is the time needed by the worker on average to do the assignment without pressure in a workstation . Methods to calculating: Directly Indirectly

16. Directly Methods Stopwatch The steps are: Measure the initial time per activity Uniformity test Sufficiency test Standard time decision

17. Directly Methods using Stopwatch Uniform Test Sufficiency test: If N’>N, then need more data

18. Standard Time Calculation Calculate the cycle time (Ws) Calculate the standard time(Wb) Calculate the normal time (Wn)

19. Standard time calculation(notes) = total measurements times N = Number of measurements P (adjustment factors) = 1+∑operator performance level k = allowance

20. Indirectly Calculation Standard Time Data Standard time data is an indirectly time measurement, by tables, curves and formulas gained by direct measurement. It is about the historical data of time needed. In addition, the standard time is known Motion Time Data It is different with company’s standard time which has been developed. Motion time data uses developed table by some institute
