A grocery chain is considering the installation of a set of 4 self-checkout lanes. The new
self-checkout lane setup will replace 2 old cashier lanes that were staffed by a cashier
and bagger on each lane. One cashier mans all 4 self-checkouts (answering questions,
checking for un-scanned items, taking coupons, etc). Checkout on the new lanes takes 2
minutes (customers bag their own orders) while checkout with the old lanes took only
45 seconds. In addition the electricity costs for both setups are $.05 per checkout while
bagging (material) costs are $.1 per checkout with the old system and $.15 for the new
system. The new lanes also require $100 in capital costs. Assume that the lanes are
always in use for 8 hours per day (1 shift) and that a worker makes $10/hour.
a. How many checkouts did the old system provide in a shift?
b. How many checkouts does the new system provide?
c. What is the multifactor productivity for each system?
