I. LEARNING CURVEA particular manufacturing job is subject to an estimated 80% experience curve. The first unit required 20 labor hours to complete.Required:a. What is the cumulative average time per unit after four units are completed?b. What is the total time required to produce 2 units?c. How many hours are required to produce the second unit?
II. PROBABILITY ANALYSISSports Club sells cold sodas at FEU’s home basketball games. In the year 2014, the frequency of distribution of the demand for cups of sodas per day is presented below:
Sales volume in cups Frequency2000 48 days5000 80 days6000 144 days8000 32 days
10000 16 days360 days
Determine the 2015’s estimated daily demand for sodas at FEU’s home game using:a. Deterministic Approach (based on most likely event)b. Expected value approach
