Maintenance Scheduling for Combined Mandatory and Periodic Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
System/facility managers face difficulties in formulating an optimal maintenance schedule for industrial machines like robots, machine tools, and peripheral equipment, as they struggle to incorporate periodic component replacement and checkup operations into existing maintenance dates, especially when mandatory maintenance is scheduled.
Innovation Solution
A maintenance scheduling device and method that acquire mandatory maintenance information, additional checkup operation information, and determine the feasibility of executing these operations within available time, automatically formulating a schedule that includes periodic component replacements and checkups on the same maintenance date.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If system/facility managers manually create maintenance schedules for multiple machines, then they can ensure mandatory maintenance is performed, but they cannot effectively incorporate periodic component replacement and checkup operations for other machines due to information limitations
Solution Approach 1:
The maintenance scheduling device automatically formulates maintenance schedules by itself, acquiring mandatory maintenance information from information management devices and autonomously determining optimized schedules that incorporate both mandatory maintenance and periodic component replacement operations, eliminating the need for manual schedule creation by system/facility managers
Solution Approach 2:
The maintenance scheduling device serves as an intermediary between information management devices and the maintenance scheduling process, acquiring necessary maintenance information from multiple machines and automatically formulating integrated schedules that balance mandatory maintenance requirements with periodic maintenance opportunities
2Loss of time
If maintenance schedules are created to include multiple operations, then shutdown time is utilized more effectively, but the difficulty of grasping all relevant maintenance information increases
Solution Approach 1:
The system implements feedback mechanisms where information management devices automatically provide mandatory maintenance information to the maintenance scheduling device, which then formulates schedules and can communicate them back, creating a closed-loop information flow that ensures complete and accurate maintenance information is captured and utilized
Solution Approach 2:
The maintenance scheduling device acts as an intermediary that centralizes the collection and processing of maintenance information from multiple sources, automatically acquiring mandatory maintenance information from information management devices and integrating it with periodic maintenance requirements to formulate comprehensive schedules
3Extent of automation
If automated maintenance scheduling is implemented, then optimal schedules can be formulated automatically, but the system requires integration with multiple information management devices
Solution Approach 1:
The maintenance scheduling device is designed with universal functionality to acquire mandatory maintenance information from multiple different information management devices that manage different machines, enabling it to automatically formulate integrated maintenance schedules across the entire production system without requiring separate scheduling systems for each machine

AI summary
When performing maintenance of a machine pertaining to required maintenance items for a robot, a machine tool, and a peripheral apparatus, etc., periodic component replacement work and inspection work of another machine is automatically added and an optimal maintenance schedule is established. The present invention is a maintenance scheduling device that: acquires a work time period pertaining to additional work required for inspection other than the maintenance pertaining to the required maintenance items; and when the additional work can be implemented within a remaining work time period obtained by subtracting the work time period for maintenance pertaining to the required maintenance items from the entire work time period set for the maintenance day, establishes a maintenance schedule to which the additional work is added.
