Abstract: A scheduler integrates worker time and location into customer appointment schedules by obtaining the status of workers' meetings with customers and forwarding updated schedule messages to waiting customers if the worker is late for an appointment due to traffic or unexpected delays at the previous customer meeting. The waiting customers receiving the updated schedules can respond by accepting the updated schedule, adjusting the meeting time or cancelling the appointment. The scheduler eliminates the need for customers to have to wait for long periods of time for service workers to arrive and allows them to adjust the meeting appointment based upon their schedules.
