Resource Reservation System Preventing Cancellation During Communication Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource reservation systems often cancel meeting room reservations if the information processing terminal cannot communicate with the information processing apparatus, leading to potential double-reservations and inefficiencies.
Innovation Solution
A resource reservation system that prevents automatic cancellation of reservations when communication between the meeting administration server and the meeting room terminal is lost, by setting the terminal state to 'disconnected' only after a predetermined time of non-communication, allowing actual users to continue using the reserved room without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the information processing apparatus cancels reservation when periodic request is not received, then resource availability is improved, but reservation reliability deteriorates
Solution Approach 1:
The system dynamically adjusts the cancellation policy based on communication status. When the terminal is disconnected, the system suspends automatic cancellation even if the predetermined time elapses, whereas when connected, normal cancellation rules apply. This dynamic adaptation resolves the contradiction by making the system flexible enough to preserve reservations during communication failures while maintaining resource availability during normal operations.
Solution Approach 2:
The communication status acts as an intermediary condition that mediates between the periodic request mechanism and the cancellation decision. By introducing this intermediate state check, the system can distinguish between intentional no-shows and communication failures, thereby protecting reservations from spurious cancellations while still enabling legitimate resource reassignment.
2Measurement precision
If the system monitors communication status continuously, then reservation accuracy is improved, but system complexity increases
Solution Approach 1:
The information processing terminal autonomously determines its own communication status by attempting to establish periodic communication with the information processing apparatus. This self-diagnosis capability eliminates the need for complex centralized monitoring infrastructure, as each terminal independently reports its availability state, thereby achieving high measurement precision with minimal added system complexity.
Solution Approach 2:
The system implements a feedback mechanism where the terminal periodically attempts to communicate with the server and reports its status. This simple feedback loop provides continuous information about communication availability without requiring complex monitoring systems, enabling accurate reservation management through regular status updates from the terminal side.

AI summary
A resource reservation system for processing a resource reservation includes an information processing terminal associated with a resource and be capable of receiving a use start operation of starting using the resource, and the information processing apparatus configured to include reservation information including a use start time of day, transmit the reservation information to the information processing terminal in response to a periodic request from the information processing terminal, and receive a use start notification from the information processing terminal in a case where the information processing terminal receives the use start operation, wherein the information processing apparatus does not perform the cancel of the reservation information if the periodic request from the information processing terminal is not received within the constant time and even if the use start notification is not received within the predetermined time from the use start time of day.
