Increasing Customer Satisfaction in Queuing Systems with Rapid Modelling

Companies have to increase their customers' satisfaction to keep their competitiveness. In services, waiting has great impact on service level and customer satisfaction. Consequently, in time-based competition, one of the main objectives of service companies is to minimize customer waiting. Waiting can be defined in several ways; however, the ultimate management objective should be the maximization of customer satisfaction. The paper shows how customer satisfaction can be approximated with utility functions and establishes a theoretical background for utility transformation of waiting time. The case study of the checkout system of a real do-it-yourself superstore is used to illustrate the application of the suggested method. The results show that utility related objective function may justify queuing system changes even if the average waiting time does not improve.
