ASSIGNMENT PROBLEM A: Consider the following four step process: -AA-Btcto- The following data are available for the four steps: A B D Activity time per unit (min) 0.25 0.33 0.2 0.5 Capacity per worker (units/min) 4 3 5 2 Number of workers 2 3 2 4 Suppose the steps in activity D are made easier, so the activity time per unit in step Dis reduced by 50% (to 0.25 minutes per unit). If the assignment of workers to steps remains the same, by how much does the capacity of the entire process increase in units per minute
