This page consists of sub pages about the different large projects I have done. I only listed the projects of the courses that were primarily project based.
Projects (Course Title- Project Title) in Chronological Order /* I think. Need to confirm and look at my transcripts... */:
Great Problems Seminar: Grand Challenges- Forest Gardening: Research project about Forest Gardening, a more effective way to garden that saves space, money, labor, etc.
Achieving Effective Operations- Yale Health Services: Research project analyzing flow and layout of the old and new Yale Health Services buildings. /* I forgot...was this the project with Kristine DeSotto, Alison and Amanda? */
Supply Chain project in Prof. Zeng's class
Facility Design project in Prof. Johnson's class
Helpdesk Simulation Project: Discrete-event simulation project (using Rockwell ARENA) of the WPI Helpdesk (a service that helps faculty and students with computer, phone, and other electronic troubles) to improve scheduling. /* If you want to see this, then I would need to ask my teammates Kristine DeSotto, Sett Paing Oo, and Prof. Konrad */
Rockwell ARENA Case Study Competition: Modeled a mining operation? I cannot remember exactly
Interactive Qualifying Project (IQP): Facilitating WeBWorK Problem Authoring aka the WPI WeBWorK GUI : Research project on creating a user-friendly Graphical User Interface (GUI) compatible with WeBWorK, an online homework system, that would make it easier for instructors to create/customize homework problems.
I made a tutorial website. My computer science major teammates made the GUI and I helped test it. Our other teammate (math major) analyzed the data from the survey (we created) and interviews we conducted. WPI math professors tested our GUI. I created tutorials using Camtasia and edited them using Adobe Premiere.
Here is the write up.
Applied Stats III: 2^K Factorial Design - Paper Airplane. Also repeated this for the graduate six sigma course Prof. Towner taught.
Technical Writing projects/documents /* One with Mao Jian! */ using Adobe Framemaker and RoboHelp
Examining the impact of regular physician visits on heart failure patients: a use case with electronic health data [Publication] - I was a Summer Undergraduate Research Fellow (SURF) during Summer 2012. We extended this work and I continued this project as my Humanities and Arts capstone/practicum with Prof. Faber. He teaches "Humanities and Hospitals." I used VBA and SAS for this project over that summer. I didn't learn SQL (from Prof. Diane Strong) until the Fall after I finished the VBA code.
MS Access/SQL project in Prof. Strong's class with my Chinese math and computer Science major friends /* I like working with Jian */
Major Qualifying Project- VA Mental Health Integration - I did some additional work. I wish we had added Evy, Laz and Sett as co-authors of the two papers that we published. It was a team effort.
Projects in Prof. Zhu's Data Envelopment Analysis Class - He published my case project in his book Data Envelopment Analysis: Balanced Benchmarking. It is on page 224-229. He gave me a free copy and wrote a nice note. Very nice man. One of my "Model Men." I find it funny that this project is the one in a book. I did this project in a very short time compared to my other projects. Optimization! Super efficiency ;)
Bike Share Kaggle Competition Project with Elisa, Scott, ??, and Dr. Aaron Birt for the Statistical Methods for Data Science class that Prof. Paffenroth taught. We used An Introduction to Statistical Learning: with Applications in R.
I forgot which methods I took for this...Principal Components Analysis (PCA?) using R
We threw a lot of methods at that data set and cross-trained.
Resource Staffing/Cross-Training/Stochastic Programming Project/Manufacturing PhD Qualifier
Prof. Johnson, Konrad and Trapp formulated a two-stage stochastic model with recourse.
I worked with the professors to find data and code a simplified version of the model (proof of concept) in MatLab and called CPLEX to solve it.
For my qualifier, I reviewed various optimization and discrete-event simulation articles on resource staffing.
I did these things in 2014 so it is a blur to me. Honestly, I forget things very easily which is why I typically write things down (document!)...except I don't write until I think I am "right." I need to change my mentality about writing and just write then edit and revise like Prof. Konrad keeps telling me. Just do it!
UMass Coronary Heart Disease Project
TreeAge (Decision Tree/Monte-Carlo/Markov/Microsimulation which is a special case of Agent-Based Modeling...) model
NetLogo (Agent-Based Model) model that I built in the online Introduction to Agent-Based Modeling (ABM) class that Prof. Radzicki teaches. He had to classify the class under System Dynamics because he could not teach it from other programs. We learned ABM using the Railsback and Grimm's Agent-Based and Individual-Based Modeling book
I made a major typo and didn't catch it on the poster I presented at Winter Sim...Heart NOT Heat. That was funny. I need to be more careful. Or people need to be more understanding/less nitpicky. Shall we build a game theory model? Mini-max? Maxi-min? ;)
"Given a (complex systems) problem, what method(s) should we use?"
Opioid Individual Model System Dynamics model with Prof. Saeed Langarudi
Filtered Water vs Bottled Water (aka modified case example of the Bass Diffusion Model) Project in Prof. Radzicki's in person System Dynamics course (Spring 2019). I tried to build the models based on his guidance. Prof. Radzicki did everything/was mentoring/showing us how to build good System Dynamics models. He spent most of class going over how he would build the model like how Prof. Sterman taught him. I contributed a small part...something about how the one time/sunk cost of a water filter is different from the water from tap but he built it. I just sat, watched, listened and thought.
