| 1. Formulate an LP model for this case. (Part A). | Did not submit or LP model is not sufficiently attempted and does not demonstrate a. recognizable attempt to model this case. | LP model is partially correct, but has errors in the objective function or constraints. Described with 70 – 79% accuracy, clarity, and completeness. | LP model has objective function and most constraints correctly specified. Described with 80 – 89% accuracy, clarity, and completeness. | LP model has objective function and all constraints fully and correctly specified. Described with 90 – 100% accuracy, clarity, and completeness. |
| 2. Solve the linear programming model formulated in Criterion 1 (Part A) | Did not submit or did not solve the linear programming model accurately. | Solved the linear programming model with 70 – 79% accuracy. | Solved the linear programming model with 80 – 89% accuracy. | Solved the linear programming model with 90 – 100% accuracy. |
