16. Why Manufacturing Matters ?  A lot of workers are in manufacturing jobs  More than half of the total R&D performed is in the manufacturing industries  Manufacturing workers earn an average of salary more than service workers  When a manufacturing job is lost, an average of 2.5 service jobs are lost

17. Challenges of Managing Services  Service jobs are often less structured than manufacturing jobs  Customer contact is higher  Worker skill levels are lower  Services hire many low-skill, entry-level workers, except specialist services  Employee turnover is higher  Input variability is higher  Service performance can be affected by worker’s personal factors

18. Decision Making of OM System Design – capacity – location – arrangement of departments – product and service planning – acquisition and placement of equipment What How Who Where When Which

19. Decision Making of OM System operation – personnel – inventory – scheduling – project management – quality assurance What How Who Where When Which

20. OM and Decision Making Tools  Models  Quantitative approaches  Analysis of trade-offs  Priorities Establishing  Ethical Issues

21. Models A model is an abstraction of reality. – Physical – Schematic – Mathematical

22. Models Are Beneficial  Easy to use, less expensive  Require users to organize  Increase understanding of the problem  Enable “what if” questions  Consistent tool for evaluation and standardized format  Power of mathematics

23. Limitations of Models  Quantitative information may be emphasized at the expense of qualitative information  Models may be incorrectly applied and results misinterpreted  Nonqualified users may not comprehend the rules on how to use the model  Use of models does not guarantee good decisions

24. Quantitative Approaches Often to obtain optimal solution to managerial problem Linear programming Queuing Techniques Inventory models Project models Statistical models

25. Analysis of Trade-Offs  Decision on the amount of inventory to stock  Increased cost of holding inventory Vs.  Level of customer service

26. Priorities Establishing (Pareto Phenomenon) A few factors account for a high percentage of the occurrence of some event(s). 80/20 Rule - 80% of problems are caused by 20% of the activities.

27. Ethical Issues  Financial statements  Worker safety  Product safety  Quality  Environment  Community  Hiring/firing workers  Closing facilities  Worker’s rights
