1.2 Two models ( Model A and Model B) of a simple product are to be produced on an assembly line. Because of the nature of demand for these products, it is preferable to design the assembly line for mixed production rather than for separate production in batches. The line output required for the two types of models, per week. Model A= 400 units and Model B = 200 units. The diagram below shows the precedence relationships of the work elements as well the elements times. Certain elements are common to both models: Model A consists of elements: 1, 2, 3, 4, 6, 7, and 8 Model B consists of elements: 2, 3, 5, 6, 7, 8, and 9 6 9 N 5 7 8 1 2 3 4 5 5 6 7 8 9 Element Element duration (min) 0.2 0.4 0.7 0.1 0.3 0.1 0.32 0.6 0.26 12.1.
