Abstract—The integration of SaaS service for group user in cloud is challenging, notably because the service’s QoS and member’s personalization QoS preference in group are uncertain. This is a timely and importance problem with the advent of the SaaS model of service delivery. Therefore, before the SaaS service been utilized, the service alternatives must be ranked for group user based on services’ QoS and QoS preference expressed by interval numbers. So, QoSaware SaaS services selection with interval numbers for group user (QSSSIN_GU) is proposed, in order to identify the pros and cons of alternatives. This approach can obtain the group optimal service when the member’s QoS preference in group is personalized and the QoS of service alternatives expressed by interval numbers. Finally, four experiments are given to demonstrate the benefits and effectiveness of QoS-aware SaaS services selection with interval numbers for group user. That is a feasible and supplementary manner in selecting the SaaS services for group user with interval numbers.
