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.
