Job Plan Creation System Prioritizing Interrupted Jobs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing job plan creation systems for production facilities fail to efficiently reconfigure job plans based on job progress, leading to wasted or duplicated processes such as preparation of cutting tools and machine setups, especially when job priorities change or jobs are interrupted.
Innovation Solution
A job plan creation system that prioritizes interrupted jobs over delayed and not-started jobs, extracts and postpones appropriate jobs based on predetermined conditions like job type and delivery time, and reverses job order to optimize resource allocation and reduce waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the job plan is reconfigured without considering the interruption state of jobs, then the job plan can be simplified and created quickly, but interrupted jobs will be postponed resulting in wasted or duplicated preparation processes
Solution Approach 1:
The system performs preliminary classification of jobs into interrupted, delayed, and not-started categories before reconfiguring the job plan. By identifying interrupted jobs in advance and prioritizing them in the reconfigured plan, the system prevents wasted preparation processes while maintaining efficient plan creation
Solution Approach 2:
The system uses feedback from job execution status (interruption, completion, delay) to dynamically adjust job priorities in the reconfigured plan. This feedback mechanism ensures that interrupted jobs are recognized and prioritized, preventing resource waste while maintaining overall productivity
2Loss of substance
If interrupted jobs are prioritized over delayed and not-started jobs in reconfiguration, then preparation processes are avoided and waste is reduced, but the complexity of job plan creation increases
Solution Approach 1:
The system segments jobs into distinct categories (interrupted, delayed, not-started) based on their execution state. This segmentation allows for targeted priority assignment without requiring complex overall restructuring, reducing the perceived complexity while achieving resource optimization
Solution Approach 2:
The system changes the priority parameter of jobs based on their execution state. By automatically adjusting priority values according to whether jobs are interrupted, delayed, or not-started, the system achieves intelligent resource allocation without complex manual intervention
3Ease of operation
If jobs are allocated without considering preparation job status, then resource allocation is simplified and faster, but preparation jobs may be wasted or duplicated
Solution Approach 1:
The system performs preliminary checking of preparation job status before allocating new jobs to resources. By identifying which preparation jobs are already in progress, the system can make informed allocation decisions that prevent waste while maintaining operational simplicity

AI summary
Provided is a job plan creation system capable of creating an efficient job plan when the job plan is reconfigured on the basis of the progress of the jobs after the completion of the jobs that day and by the job starting time of the following day, for example. A job plan creation system extracts an interrupted job that has been started but has not been completed, a delayed job that should have been started based on the job plan but has not been started, and a not-started job that is scheduled to be started on the job plan and so has not been started from the job plan, and creates the job plan while setting priorities in the order of the interrupted job, the delayed job and the not-started job.
