Abstract: Techniques relate to facilitating assignments of tasks to promote efficient resource timetables. A first communication from a client device is received that corresponds to an electronic request to sue a resource to complete a task. A task type of the task and a client corresponding to the electronic request are identified. Usage data corresponding to the task type and client are identified. A task-assignment duration is defined based on the usage data and a buffer time period. An availability in a timetable of a resource that is of a duration that is at least as long as the task-assignment duration is identified. A second communication identifying a start time of the availability is transmitted to the client device. A third communication is received that accepts the start time, and a fourth communication is transmitted to a device controlling use of the resource that identifies the client, task and availability.
