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

DataExtractionProcedure

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
