Academic Experiences
“Improvement of Beds Rotation System in VA Hospital”, August 2012 – January 2013
It is a team-work six sigma green belt project that is going to improve beds rotation efficiency
for shortening hospital’s waiting list.
 Apply DMAIC methodology to identify and eliminate the dominant process variation
sources.
 Collect, analyze and quantify data that enable process improvement.
 Apply data analysis and problem solving tools, like Minitab and Arena, to calculate
the optimal results on both analytical and simulative ways.
 Improve beds rotation system by increasing beds cleaners working efficiency from 71%
to 85%, theoretically.
“Visualization of Tesserae Authors’ Network”, June 2013 - March 2014
It is a multi-area project which refer to database building knowledge and visualization social
network skills.
 Apply SQL to build a huge database based on UB Classic Department raw data.
 Filtrate most concern data which score is higher than 9.5.
 Build early multiple layers of database and deeply analyze data and pick up valuable
information with SQL code.
 Convert table-type data to vivid network view with visualization tool GEPHI.
Thesis
“Evaluating Shortfall Distribution in Periodic Inventory Systems with Stochastic
Correlated Demands and Leadtimes”, April 2014 - February 2015
It is my master’s thesis which is going to calculate minimum safety stock of distributor in
supply chain when demand size from customers and lead time from suppliers are totally
stochastic and correlated.
 Establish mathematic model of the whole process in MATLAB.
 Simulate the all steps in ARENA.
 Compare analytical results from MATLAB and simulation results from ARENA in
MINITAB.
 All processing results and final results are all in 95% confidence interval which
means research model built in MATLAB is correct. Hence, there is a way to figure
out distributor’s safety stock although demands and lead times are not stable.
