Optimization of Multi-skill Call Centers Contracts and Work-shifts

Cordone, Roberto; Piselli, Andrea; Ravizza, Paolo; … - In: Service Science 3 (2011) 1, pp. 67-81

Call centers are complex systems in which it is essential to optimize the trade-off between the service level provided to the customers and the cost for the personnel. In this paper we describe a quantitative approach to choose the most suitable contracts to hire the call center operators. The...
