Approver Selection Optimization for Access Management

We describe the problem of matching approvers to access requests in a dynamic environment at IBM. We cast the problem as a minimum-weight set-covering formulation and develop an integer-programming methodology to efficiently solve instances in a real-time environment. Our solution, which has been successfully deployed at IBM, uses state-of-the-art optimization tools from COIN-OR.
