These programs optimize the staffing in a multi-skill call center for a single period.

The user must install his own solver library in order to run the cutting-plane optimization.

Implemented Java solver interface : Ilog Cplex (tested with Cplex 8 and 9) and Opsresearch solvers. Later version of Cplex (up to latest version 12.5) should be compatible.
Unfortunately, Opsresearch has been discontinued since many years and it seems to have disappeared from the web. Their jar package is made available here: or124.jar.
