Helpful Hints for Application of OM

Topic

Hints
Control Charts Modify my Excel worksheet, R50425e.xls, to create control charts for at least two important variables.  Show at least one of these control charts out of control. Implement some change.  Show control charts back in control.
Process Analysis Document two processes using Process Flowcharts.  Modify my Excel worksheet, R506rfe.xls, to create the flowcharts.  Have at least 10 steps in each flowchart with no more than 60% of any one type (O → ■ D ▼).  In your Analysis Section, revise the two flowcharts.  
Factor Rating
(see Ch 7 Supp)		 Create a table of factors vs. sites that summarizes the important information and provides a basis for the assigned scores.  Provide a credible rationale for the weights that discusses the relative importance of the factors.  For each factor, provide a credible rationale for the scores that justifies the relative importance of each site.  Have at least one negative entry in each column of the Comparison Matrix.
Facility Layout Consider at least four criteria, such as face-to-face communication, safety, flexibility for new products, time to implement.  For Analysis Section, use the Factor Rating explained above (where the layouts correspond to sites) to select the best layout.
Work Measurement (Time Standards) Modify my Excel worksheet, R508S4e.xls, to determine the time standard(s).  Typical analysis may involve using the value of the time saved to justify the cost of the new technology.
Learning Curves Modify my Excel worksheet, R50806.xls, to create at least two learning curves.
Project Management Have at least ten activities. Have no more than 50% of the tasks as critical tasks. Provide a credible rationale for the major task times.  Typical analysis may involve revising some initial task times in order to reduce a costly overrun.
Selecting Suppliers Consider at least three suppliers and at least four criteria, such as service quality, cost, knowledge, technical support, . . .  .  For Analysis Section, use the Factor Rating explained above (where the suppliers correspond to sites) to select the best supplier.
ABC Analysis Clearly explain the different inventory control procedures for the three classes of inventory items (Classes A, B, and C). Justify all assumptions of any model, such as EOQ (values of holding cost and ordering cost).  Analyze a small sample (20-30 items), then project the cost savings to the entire inventory.  For some cases, my Excel worksheet, ABCAnalysis.xls, found in Chapter 12, may be helpful.
MRP and CRP For the Application Section, present a Master Production Schedule with at least 3 products and 6 time periods (see Russell page 553). Present the Bills of Material (Figure 12.6) for the products included in the Master Production Schedule. Develop the time-phased Inventory Records (Example 12.1) for at least 3 important components by modifying my Excel worksheet, aommrp.xls found in Chapter 14. 

For the Analysis Section, present the inventory usage data for the 3 important components if MRP were not used. Determine the reduction in inventory costs for these 3 components using MRP. Then project the reduction in inventory costs for the entire inventory. Finally, include the costs of developing and operating the MRP system to determine the net savings.  If appropriate, include the evaluation of at least one PC MRP package.

Create similar files and analysis for a CRP project.
Waiting Lines Justify all assumptions, such as the Poisson Arrival Rate and the Exponential Service Time. Justify the value of the customer waiting time cost.
All topics For your Analysis Section to be convincing, there must be a strong link between the data presented in the Application Section and the financial results presented in the Analysis Section.
