Transactional Complexity Evaluation for Human-Machine Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional approaches fail to accurately evaluate the complexity of processes involving humans and computer systems, as they do not consider humans as part of the system during the evaluation process.
Innovation Solution
A method and apparatus that determine the complexity of transactions by calculating the natural log of the inverse product of success probabilities from state diagrams associated with both human and computer system entities, incorporating empirical observations for human state transition probabilities.

Engineering Contradiction Analysis
1Measurement precision
If conventional structural, informational, or descriptive complexity formulae are used, then the complexity of non-human processes can be determined, but they cannot evaluate processes involving humans in the loop
Solution Approach 1:
The patent segments the human-in-the-loop process into distinct components: human actions, system actions, and their interactions. By creating separate state diagrams for human and system entities and evaluating their probabilities independently, then combining them through the transactional complexity formula, the method achieves both measurement precision for each component and versatility for the overall human-system process evaluation.
2Productivity
If designers use rough estimates of complexity, then design decisions can be made quickly, but the accuracy of complexity evaluation is insufficient
Solution Approach 1:
The patent applies preliminary action by pre-defining state diagrams, transition probabilities, and the transactional complexity formula before actual design evaluation. This framework allows designers to quickly evaluate multiple design alternatives using the established mathematical model, maintaining both speed and accuracy. The state diagrams and probability assignments are prepared in advance, enabling rapid calculation when design decisions need to be made.

AI summary
One embodiment of the present invention provides a system that determines the complexity of a transaction between a first entity and a second entity. The system starts by determining a first probability of success for a portion of the transaction which is associated with actions of the first entity. The system then determines a second probability of success for a portion of the transaction which is associated with actions of the second entity. The system next calculates a transactional complexity for the transaction based on the first probability of success and the second probability of success.
