|Grading Rubric for Stateline Shipping & Transport Case Problem
There are 12 points in each of the five criteria for a total of 60 points possible
|Criteria||0 Unacceptable (0 points)||1 Developing (6 points)||2 Competent (9 points)||3 Exemplary (12 points)|
|1. Develop a transportation model for shipping from the 6 plants directly to the 3 disposal sites. Describe and implement the model.||Did not submit or the objective function and/or constraints are specified with less than 70% accuracy.||The objective function and constraints are specified and described with 70 - 79% accuracy.||The objective function and most or all constraints are specified correctly and adequately described.||The objective function and all constraints are specified correctly in the model and clearly described|
|2. Solve the model given in 1 and describe the results.||Did not solve the model or adequately describe the results.||The model is solved, but its validity is questionable or it is incorrectly described.||The model is solved and the results are mostly valid and mostly correctly described.||The model is solved and the results are valid and correctly described.|
|3. Develop a transshipment model in which each of the plants and disposal sites can be used as intermediate points.||Did not submit or the objective function and/or constraints are specified with less than 70% accuracy.||The objective function and constraints are specified and described with 70 -79% accuracy.||The objective function and most or all constraints are specified correctly and adequately described.||The objective function and all constraints are specified correctly in the model and clearly described|
|4. Solve the model given in 3 and describe the results.||Did not solve the model or adequately describe the results.||The model is solved, but its validity is questionable or it is incorrectly described.||The model is solved and the results are mostly valid and mostly correctly described.||The model is solved and the results are valid and correctly described.|
|5. Interpret the models and draw conclusions||Did not complete the assignment or interpretation and/or conclusions drawn are invalid and/or not intelligibly communicated.||There are errors in interpreting the results; or inappropriate conclusions are drawn; or this is not clearly communicated.||Results are interpreted in a mostly correct manner; conclusions drawn are mostly appropriate; and communicated in a mostly clear manner.||Results are correctly interpreted; appropriate conclusions are drawn and communicated clearly.|
