Conclusions
Project Overview Purpose is to create a decision support system for the
Beijing Municipal Environmental Protection Bureau (BMEPB)
Objectives of the AQMDSS:
Help BMEPB to understand the contributors to poor air quality
Provide source apportionment tools
Simulate control decisions
Produce next day air quality forecasts
Team Members Project management

Database Design Robust
Referential integrity included within structure
Range constraints to reduce processing errors
Flexible
User interface for adding data to lookup tables
Designed for multiple models– NEI 3.0 + country codes– Additional tables and fields to support processors
and models in the AQMDSS
Includes spatial data for use with GIS
Connectivity No changes to models
Extractors to read data from database
Extract data from database to file structure required by a model
Use parameter values from MIMS scenarios
Convert from metric system to units required by the models
Inserters to write data to the database
User selects data to add to database for later analysis

User Interface Designed to minimize data entry errors
Drop-down boxes and browsers for codes
Screens support referential integrity–Parent/child frames support parent/child
relationships in database
Additional range-checking
Multi-Lingual User Interface MIMS GUI
Editing Java source code to replace strings with lookups to Properties files
Data entry GUIs
Java code looks up strings to display
All strings are in files in the file system to simplify translation and maintenance
Providing AQMDSS using both Chinese and English strings
Easily translatable to other languages (e.g., Spanish)
Default is English for any string not found in target language
Conclusions AQMDSS currently in development
Beijing-based research groups to transfer data from existing databases
Testing next year
Delivery by end of 2005
User training to be performed in both Beijing and the United States
