Job Control System Parameter Dependency Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current job control systems in document processing systems face challenges in efficiently handling changes to processing parameters during job execution, leading to unnecessary job aborts and recalculation of intermediate results, which increases response time and costs.
Innovation Solution
A job control system that includes an identifier to mark dependencies of intermediate and final results to parameters, a verifier to assess the validity of these results after parameter changes, and a means to store reusable results, allowing for the reuse of valid intermediate results without full recalculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parameter changes are handled by aborting the job and recalculating all intermediate results, then processing accuracy is maintained, but response time increases and productivity decreases
Solution Approach 1:
The patent segments the job processing into independent intermediate results, each with identified parameter dependencies. When a parameter change occurs, only the affected segments are recalculated while others are reused, resolving the contradiction between maintaining accuracy and improving response time.
Solution Approach 2:
The system performs preliminary identification of parameter dependencies for each intermediate result before execution. This preliminary action enables the verifier to quickly determine which results need recalculation after parameter changes, avoiding full job aborts while maintaining processing accuracy.
2Reliability
If parameter changes are handled by aborting the job, then processing reliability is maintained, but loss of time increases
Solution Approach 1:
The verifier component provides feedback by checking parameter dependencies of intermediate results against changed parameters. This feedback mechanism maintains processing reliability by identifying affected results while minimizing time loss through selective recalculation rather than complete job aborts.
3Manufacturing precision
If all intermediate results are recalculated after parameter changes, then manufacturing precision is maintained, but productivity decreases
Solution Approach 1:
The patent applies local quality by treating each intermediate result individually with its own parameter dependency profile. This allows selective recalculation of only those results with changed parameters, maintaining manufacturing precision for affected results while improving overall processing efficiency.
Solution Approach 2:
The system monitors parameter changes and uses them to determine which intermediate results require recalculation. By linking parameter changes to specific intermediate results through dependency identification, the system maintains accuracy for affected results while avoiding unnecessary recalculation of others, thus improving productivity.

AI summary
A job control system for a document processing system wherein a number of tasks is performed in a workflow includes a user interface to define or change parameters. The job control system includes an identifier to identify and mark dependencies of one or more intermediate and/or final results to parameters. This enables a verifier, also part of the job control system, to verify, during execution of the job, a change in parameter and to determine whether or not an intermediate and/or final result obtained before the change in parameter is still useable despite the occurred change in parameter. The job control system furthermore includes a memory for storing the usable intermediate and/or final results. This enables, in case a parameter is changed, to use those results that are still useable, thus saving time.
