Solution Overview

Problem

In social simulations, the linkage destination between simulators often changes based on the data state and simulated policies, requiring significant labor for creating or updating control in each simulator.

Innovation Solution

A data control method that uses a control unit to execute logic based on action logic, determining data transmission destinations among simulators based on pre-stored target attributes, facilitating efficient data transmission and reducing the need for simulator-specific linkage descriptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional simulator linkage methods (FMI/HLA) are used to enable data sharing between simulators, then overall simulation capability is achieved, but the work of creating or updating control in each simulator requires much labor when linkage destinations change

Engineering Contradiction:
Improvelinkage destination flexibilityVSAvoidcontrol creation and update labor
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent introduces an integrated simulator system as an intermediary that manages data transmission between multiple simulators. This mediator handles the complexity of linkage control, allowing individual simulators to focus on their specific simulation functions while the integrated system manages the dynamic routing of data based on changing linkage destinations

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements dynamic linkage destination determination by allowing the integrated simulator system to adaptively route data between simulators based on changing simulation states and policies. The linkage destinations are not fixed but can be dynamically adjusted without requiring manual updates to each simulator's control code

Inventive Principle:
Principle #15Dynamics

2Reliability

If data transmission waits for all simulators to be ready, then data consistency is maintained, but transmission efficiency decreases

Engineering Contradiction:
Improvedata consistencyVSAvoiddata transmission efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The integrated simulator system performs preliminary actions by pre-establishing data transmission pathways and preparing receiving simulators in advance. This allows data to be transmitted as soon as it becomes available at the source simulator, rather than waiting for all simulators to be simultaneously ready, thus improving transmission efficiency while maintaining data consistency through the coordinated management of the integrated system

Inventive Principle:
Principle #10Preliminary action

AI summary

A data control device (1) successively executes logic based on action logic that describes action of an object. When the fact that the object has moved to a predetermined position is notified from a traffic simulator (3A) in accordance with execution of specific logic, the data control device (1) determines to which of a first shop simulator (3B) and a second shop simulator (3B) data of the object is to be transmitted using an attribute of the object stored in advance. The data control device (1) transmits the data of the object to the shop simulator (3B) to which the data of the object is determined to be transmitted. Such processing of the data control device (1) can be applied to social simulations used in a local government or a transportation infrastructure, for example.
