DESCRIPTION
ABSTRACT:
Muhammad Ashraf, General Manager Finance and Administration, Lahore University of Management Sciences, was getting increasing complaints that telephone calls were not being attended by operators. Data on the operator service times for different calls, and call arrival pattern is given. At the surface the problem seemed to be that of not enough servers (or inefficient servers). However, mathematical analysis using spreadsheets showed that the problem lay somewhere else.
