| Research Abstract |
The purpose of this research is to utilize a methodology and a tool for modeling, simulating and implementing the massively distributed control software for factory automation system based on object-orientation. The following results were obtained.
1) Evaluation of utilization for proposed tool for simulation and modeling.
A systematic methodology was proposed for implementing the simulation models described by Statecharts and event chain model as Java code by using design patterns. And the methodology was implemented by applying a CASE tool and a Java development tool. It was applied to designing and verifying the distributed control system for a practical air-control system. As a result, the design and verification could be completed in two weeks, and it was confirmed the design period could be greatly reduced.
2) Integration of simulation with implementation for distributed control system.
A transformation method from the simulation models described by Java code to the implementation code described by Neuron-C was developed based on the design patterns. It can be applied to developing the control software for material handling unit of factory automation. As a result, the effectiveness of the proposed method was confirmed.
3) Software testing method and tool for verifying implemented code of control nodes based on timed I/O Statecharts.
A testing method and a tester tool were developed by Java code where the black box testing can be automatically applied for the implemented code of simulation models generated from timed I/O Statechart. They were applied to testing the control code for air conditioning system, and it was confirmed that a testing period could be reduced to only one day by using the proposed method and tool.
