The system automatically identifies a set of service requirements and clearance requirements for a given trip, and handles tasks involved in arranging service providers for the set of service requirements to allow scheduler to self-build the trip. The system further obtains necessary information to automatically populate necessary forms to obtain the required clearances for the trip. Service requests and confirmation for the service requests are archived with reference to the service requirement of the trip and the parties relevant to the requests and confirmation are provided with real-time notification for receipt of such communications. The system also employees an online auction scheme to promote competition among the service providers to provide the schedulers with higher quality of service at lower price.
