Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an effective evaluation function for proper control plans, control-oriented evaluation and execution functions, and correcting and verifying functions for maintaining service quality based on agreed service levels in complex service structures involving multiple job application systems.
Innovation Solution
A feed-forward control method and system that integrates monitoring and control of distributed component workflows to maintain agreed service levels by storing service level information, calculating measurement statistics, predicting future states, and adjusting execution environments to ensure compliance with predetermined service quality targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional traffic control technology is used to manage communication traffic in complex service structures, then basic communication flow can be controlled, but service quality based on agreed service levels cannot be maintained
Solution Approach 1:
The patent introduces a service level management device as an intermediary component between the service providing device and service receiving device. This mediator captures service level information from multiple services, integrates it into unified service level definitions, and manages the overall service quality. The intermediary handles the complexity of coordinating multiple services while maintaining clear interfaces with other system components.
Solution Approach 2:
The service level management device performs multiple functions including capturing service level information from various services, integrating disparate service level definitions, managing service quality policies, and coordinating with workflow management systems. This multi-functional approach consolidates what would otherwise require multiple separate control mechanisms into a single universal management system.
2Adaptability or versatility
If multiple job application systems are arbitrarily associated using workflow managing systems to create complex service structures, then service flexibility and adaptability improve, but service quality control becomes difficult
Solution Approach 1:
The system implements feedback mechanisms where the service level management device continuously monitors service level information from multiple services, compares actual performance against agreed service levels, and triggers notifications when service quality deviations occur. This feedback loop enables dynamic adjustment and maintenance of service quality despite the flexible, arbitrarily-associated service structure.
Solution Approach 2:
The patent establishes service level definitions and agreements before services are executed or associated in the workflow system. By pre-defining service level requirements, performance thresholds, and quality criteria, the system prepares control parameters in advance that guide subsequent service quality management, enabling consistent quality control across flexible service compositions.
3Reliability
If service level information from multiple services is integrated and managed, then overall service quality control improves, but information processing complexity increases
Solution Approach 1:
The service level management device segments service level information management into distinct functional components: service level information capture from individual services, service level definition integration, quality threshold management, and notification generation. This segmentation allows each component to handle specific aspects of service level management independently, reducing the complexity of the overall information processing task.

AI summary
A service provision quality control device according to the present invention includes a simulation processing unit which predicts a group of state predicting vector values on the basis of vector values of a current state and a past state of measurement statistic, a judging unit which judges whether a control operation is necessary or not on the basis of the state predicting vector value and a target state vector value whose control target is agreed service level, and an adjusting unit which adjusts evaluation condition of an execution environment repeatedly until control deviation becomes not larger than a predetermined value under the condition that iteration number is not larger than a predetermined value which is corresponding to an upper limit value.
