Abstract: A computational network system that permits service a group of technicians access to the manufacturer network to provide their work capacity and availability for a specific area. A customer contacts the manufacturer via the computational network system, requesting a service call. Service call request processing results in assigning a service request/demand to a technician based on their qualifications, availability, and proximity. When a service technician is assigned, their availability is decremented. Cancellation of a service call yields an increment in the affected service provider's availability. This information is stored in a in an on-line database residing in the network system. Updates are dynamically reflected as they occur resulting in automated schedule administration of a customer's service requests/demands.
