1. Penin State WebMa 0/2 pts correct Question3 Argus technologies produces advanced sensor
technologies for the military. As such, the productions run on a monthly level are relatively
small. Since Argus is in competition with other firms, it is making every effort to be as efficient
as possible. Below you'll find some data on the final assembly for three of the most advanced
sensor products produced by Argus Worker Productivity Units/Hour 0.07 0.10 0.08 Required
Production 120 200 140 Workers 13 LIDAR 10 How many hours are required for the LLTV line
in order to meet the production quota? 1714 How many hours are required for the IR line in
order to meet the production quota? 2000
Solution
Part 1:
Data for LLTV
Production target = 120 units
Worker productivity = 0.07 units/hour
Time required to produce 120 units per worker = 120 units/(0.07 units per hour) = 1714.28 hours
With 9 workers the hours required to achieve production target = 1714.28/9 = 190.47 hours
Hours required for the LLTV line to meet target = 190.47 hours
Data for IR
Production target = 200 units
Worker productivity = 0.10 units/hour
Time required to produce 200 units per worker = 200 units/(0.10 units per hour) = 2000 hours
With 13 workers the hours required to achieve production target = 2000/13 = 153.84 hours
Hours required for the IR line to meet target = 153.84 hours
Part 2:
Labor productivity in 2014 = units produced/Labor hours = 20,000/3,000 = 6.67 units per hour
Labor productivity in 2015 = units produced/Labor hours = 27,000/3,950 = 6.84 units per hour
% change in labor productivity = (Productivity in 2015 – productivity in 2014)/productivity in
2014 = (6.84-6.67)/6.67
% change in labor productivity = 2.55%
