2 Preliminaries : Bounds and expansions for Erlang C

  title={2 Preliminaries : Bounds and expansions for Erlang C},
  author={A. Janssen and J. V. Leeuwaarden and B. Zwart},
We apply a new corrected diffusion approximation for the Erlang C formula to determine server staffing levels in cost minimization and constraint satisfaction problems. These problems are motivated by large customer contact centers that are modeled as an M/M/s queue with s the number of servers or agents. The proposed server staffing levels are refinements of the celebrated square root staffing rule, and have the appealing property that they are as simple as the conventional square root… CONTINUE READING
