of IMS-VIPNET project to Fiscal 2002 | |
(1) Task1-1:
Design of Technology Knowledge Infrastructure Architecture |
We
continued to study a system that will make data management more sophisticated
and useful, based on GPM expressions developed in the previous fiscal year.
We also extended the basic infrastructure based on 4 layers: The layer for
connecting existing systems (layer 1); the data integration layer (building an
ontology, conversions and databases corresponding to each data ontology, etc.)
(layer 2); the layer for applied Technology Knowledge Infrastructure technologies
(data mining technologies, safety assessment technologies, and environmental impact
assessment technologies) (layer 3); and the user presentation layer (display of
attributes / documents / 2D & 3D figures via the Internet) (layer 4). |

Task1-2: Building a Technology Knowledge Infrastructure
Environment |
We
developed programs necessary for technologies to convert CAD data to GPM data,
and convert data in GPM format back to CAD data (CAD data conversion server).
Additionally, the Tokyo Internet Research Center (TIRC) widely published CAD data
in the Internet environment, and performed experiments on sharing class libraries
that will serve as the core of the ontology.
| | *Plant
Data Warehouse Infrastructure | Focused on a database based on GPM expressions for the integrated
management of information relating to the
plant life cycle, including design, operation, maintenance, and disposal.
| | *CAD
Data Conversion Server | In order to enable the reuse of total plant life cycle and
increase the value of data assets, we notonly converted
and accumulated plant data in the GPM DB, but also converted needed datafrom
the GPM DB, in a format suitable for business support systems, and built a mechanismfor
providing data. In other words, we made it possible to convert data back and forth
betweenthe GPM DB and business support systems. | CAD data has a more complex structure than the data used
for ordinary e-commerce. We aimedto develop a system
that would provide bi-directional conversion capability for data included anumber
of geometrical shapes. | We performed verification testing on the system, and confirmed
its usefulness.

Task1-3: Verification
Testing of Virtual Enterprise Network via Technology Knowledge Infrastructure
Last
year, we developed CPM, GPM-XML, data warehouse functions, and agent functions,
based on basic Technology Knowledge Infrastructure architecture.
We applied these
to some actual process plants, and performed verification testing of accumulation
and sharing of information and technology, and verified the usefulness of basic
architecture and GPM, GPM-XML, data warehouse functions, and agent functions.
This fiscal year, we performed
the experimental verification of bi-directional data conversion between
CAD and GPM-XML as shown in. We conducted basic studies on the possibilities of
creating a flow of data between Virtual Enterprises inside and outside the company,
via functions for integrating data with GPM DB, and converting data from the GPM
db back to CAD data.Additionally, we used the TIRC verification environment
to test the ability of the Technology Knowledge Infrastructure browser to run
in an enterprise that has a firewall set up, and measured the times taken to display.
For test data, we used a virtual 3D model of a process plant having a relatively
large amount of data.
Through this we were able
to confirm the ability of the Technology Knowledge Infrastructure browser to send
and receive data from behind a firewall, and send and received data without stress.
