Plant Control Team Support Using Work Substitution Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant monitoring and control systems lack a team work perspective, leading to suboptimal performance even when individual operator efficiency is improved, as they do not effectively present information to facilitate cooperative work among multiple operators.
Innovation Solution
A plant monitoring and control apparatus and method that includes an input/output unit for each member, a monitoring and control procedure database, a procedure progress database, a status evaluation unit, a support content determination unit, and a presentation information generation unit, which work together to evaluate member status, identify support needs, determine work substitution possibilities, and generate presentation information to optimize cooperative monitoring and control.

Engineering Contradiction Analysis
1Productivity
If information presentation is optimized for individual operators based on their workload and skill level, then individual operator efficiency is improved, but team cooperation performance does not necessarily improve
Solution Approach 1:
The system merges individual operator status evaluation with team-wide work distribution optimization. The information presentation unit not only presents information tailored to individual operators' workload and skill levels but also coordinates across the team to optimize overall work distribution, thereby combining individual efficiency gains with team cooperation performance improvement.
Solution Approach 2:
The system implements feedback mechanisms where the status evaluation unit continuously monitors individual operator status (workload, skill level, current tasks) and feeds this information back to the information presentation unit. This feedback loop enables dynamic adjustment of information presentation and work allocation, ensuring that both individual efficiency and team cooperation are maintained and optimized.
2Reliability
If the system monitors and evaluates detailed status of each team member to enable work substitution, then team cooperation is improved, but system complexity increases
Solution Approach 1:
The system segments the complex task of team status monitoring into distinct functional modules: a status evaluation unit that collects and processes individual operator data, a work content determination unit that analyzes work substitution possibilities, and an information presentation unit that communicates relevant information. This segmentation reduces overall system complexity by dividing the monitoring function into manageable, specialized components.
Solution Approach 2:
The status evaluation unit serves multiple functions: it monitors individual operator status, evaluates team-wide work distribution, identifies candidates for work substitution, and provides data for information presentation. This multi-functionality reduces system complexity by consolidating multiple monitoring and evaluation tasks into a single versatile unit rather than requiring separate systems for each function.

AI summary
An apparatus comprising: a procedure progress database in which progress status and identification information of a relevant member are recorded for each of pieces of work; a team status evaluation unit which identifies a member requiring support on work in the monitoring and control within a team; an operation support content determination processing unit which determines, as support content, information on the possibility of substitution by a member having the operation authority for the work that the identified member is scheduled to perform; and a presentation information generation processing unit which selects a plurality of persons including the identified member as presentation targets of the determined support content, and generates presentation information in accordance with each of the selected persons.
