2. Consider three models to be made on a single assembly line. Presented below is the information related to the 3 models with the process times and precedence diagrams for each model (model 1, 2, and 3), cycle time (in hours) of each task is given in the diagram as well. Using the ranked positional weight heuristic, design a mixed model assembly line with a cycle time of CT=2.8hr, assuming the weight assigned to each model is equal
