National Center for Transportation and Industrial Productivity, Newark, NJ

Nexus Supply Chain Management System

• Developed and maintained a MySQL database to store/update supplier, materials and

demand data

• Analyzed the relationship between profit allocation and inventory control

• Implemented a web application with ASP.net/MVC to create a website for users to input

and update supply chain model data and display model output in table and graphic form

Implementation of Maintenance Decision Support System in New Jersey, FWHA-NJDOT

• Initiated a Python script to automatically retrieve and convert weather forecast data

• Designed weather information database in MySQL server and wrote SQL store procedures

• Developed a integer programming model using CPLEX to minimize the service time of

salt spreading operation in winter period

Variability of Travel Times on New Jersey Highways, FWHA-NJDOT

• Collected and analyzed travel time data collected on I-295 using TRANSMIT, Bluetooth,

INRIX and GPS Techniques

• Developed a DP model using to optimize travel time data collection schedule for a traffic

network with 20 routes in New Jersey. Operation cost was reduced by 30%
