| 1. Model number of days to repair |
Did not submit or did not model this component in an appropriate manner |
This component was modeled, but the method and/or implementation had mistakes that affected the validity of the model |
Used a method that is recognizably appropriate, but the implementation had minor mistakes |
Used an appropriate method and correctly implemented it |
| 2. Model number of weeks between breakdowns |
Did not submit or did not model this component in an appropriate manner |
This component was modeled, but the method and/or implementation had mistakes that affected the validity of the model |
Used a method that is recognizably appropriate, but the implementation had minor mistakes |
Used an appropriate method and correctly implemented it |
| 3. Model lost revenue due to breakdowns |
Did not submit or did not model this component in an appropriate manner |
This component was modeled, but the method and/or implementation had mistakes that affected the validity of the model |
Used a method that is recognizably appropriate, but the implementation had minor mistakes |
Used an appropriate method and correctly implemented it |
| 4. Provide written description and explanation of the simulation |
Did not submit or described insufficiently. Omitted key points. |
Provided partially developed written description that matches the method 70 - 79% accuracy. |
Provided sufficiently developed written description that matches the method 80 - 89% accuracy. |
Provided fully developed written description that is correct and matches the method used with 90 - 100% accuracy. |
| 5. Combine model components to produce a coherent answer to the question posed in the case study. (a) Answer the question posed in the case study. (b) How confident are you that this answer is a good one? (c) What are the limits of the study? |
Did not submit or result not provided, and/or discussed insufficiently. |
Provided partially correct result. Omitted discussion of confidence. Discussed limitations partially with 70 - 79% accuracy, logic, and clarity. |
Provided sufficiently correct result. Identified confidence and discussed limitations sufficiently with 80 - 89% accuracy, accuracy, logic, and clarity. |
Provided fully correct result. Identified confidence and discussed limitations fully with 90 - 100% accuracy, logic, and clarity. |
