Description of main characteristics of Mass Maintenance Systems is given. Problems of queuing system effectiveness due to loss of time for both arrivals while waiting for service and for servers waiting for arrivals are discussed. System with changeable number of servers is proposed. Calculations are made in order to find out what is influence of main queuing system parameters on the total operational cost regarding time losses. It is shown that decision about system structure depends mainly on system service index and server initial cost.
