The supervisor in charge of the Arrival line had the Arrival Coordinator position combined with himself. He was never trained on the [Arrival Coordinator] or Arrival positions so his knowledge is limited at best. He inundated the Arrival Controller with too many airplanes. The Arrival Controller was forced to vector airplanes outside of his airspace for an extended period of time. Aircraft were pulled off the final and several were sent around because the Supervisor/Arrival Coordinator did not take into account a scheduled runway inspection. The Supervisor failed to provide any guidance to the Arrival Controller possibly because he did not know what to do himself. This created a very chaotic and unsafe situation. Do not combine positions with the Supervisor with any more than light traffic and don't combine positions with a Supervisor who has never been certified on those positions. Mandate that Supervisors will be trained on the positions that they supervise so they can help and not hinder the operation.
Traffic Management Coordinator reported that an unqualified Supervisor working several positions created significant traffic problems.
