We propose a multi-step procedure that integrates fuzzy clustering analysis and

data envelopment analysis (DEA) to group bank branches into managerial

clusters and to investigate their operational performance. We build and expand

on previous research by including fuzzy clustering. We look for changes in

clustering composition due to branches belonging to multiple clusters, and

changes in operational efficiency performance due to fuzzy clustering. All this

while looking at influential branches. Our premise is that fuzzy clustering allows

differentiating clusters beyond scale/size, and that it affects operational efficiency

performance.

1 - Identifying New Service Opportunities For Driving Safety

Enhancement Based On Driving Behavior Analysis: Commercial

Vehicle Case In Korea

The goal of this research is to identify service opportunities for enhancing driving

safety for commercial vehicles (including intra-city buses, express buses, and

trucks). Based on an analysis of vehicle operational data in conjunction with

accident data, new service opportunities for enhancing driving safety are

identified. The service opportunities would contribute to developing new services

for commercial vehicle companies and related authorities in Korea.

2 - Development Of A Daily Health Behavior Index For

College Students

Recently, a smart wellness service has been developed to support daily wellness

management for college students. During a day, the service collects health

behavior (activities, sleep, and diet) data of a student via smart devices. As part of

the service, a daily health behavior index was developed to evaluate the student’s

health behaviors based on the collected data. Daily health behavior data of 47

college students were collected during a four-week experiment and used to

develop the index. This talk presents how the index was developed and utilized in

the service.

1 - On-site Personalized Product Recommendations: A Field Study

Consumers receive on-site personalized product recommendations about

alternative products based on their past behavior. In this paper, we study the

effectiveness (click and purchase) of these recommendations based on products

(1) browsed, (2) put on wishlist, or (3) bought, using a large dataset from a major

e-retailer. We examine the extent to which these effects differ for products with

different price levels, in different product categories, as well as depending on how

long after the initial interaction with the product source are the recommendations

presented. The findings provide suggestions for improving the on-site

recommendation for e-commerce websites.

An Empirical Study

Use a unique dataset collected from one of the largest classified ads website in

China, we empirically examine the effect of offline call intensity on online

customer purchase probability and the carryover effect of call intensity. We find

that online customer purchase probability is increasing in call intensity but at a

decreasing rate. In addition, there exists a strong carryover effect where the call

intensity in the past 4 weeks does not fade away but have a positive effect on

recent customer purchase. Our estimations show that both too much or too little

call intensity will result in considerably worse outcomes.

Websites retarget their customers by sending e-mail with personalized product

recommendations based on their past browsing behavior and preferences. In this

study, we examine the effectiveness of such e-mail communication across two

types of product recommendations: content-based recommendations and visual

recommendations. We conducted a large-scale randomized field experiment to

investigate how these effects vary depending on customers’ purchase stage and

the temporal distance between their last website visit and receiving the email. The

study provides insights for e-commerce websites regarding the improvement of

their e-mail retargeting campaigns.

1 - A Decision Framework For Uber-like Transportation Platform

The rising platforms such as Uber, Lyft and Sidecar empower individuals to

provide short-range point-to-point ridesharing services other than traditional

transportation services (e.g. bus, subway, taxi). This paper aims to provide

decision support tools for such peer-to-peer transportation businesses. We divide

the business operations into three stages: resource identification, resource

allocation and task assignment, and use optimization models and prospect theory

in decision making to formulate the three stages. Computational results will be

reported.

This project applies machine learning to remotely sensed imagery to train and

validate predictive models of vegetation health. We processed eleven years of

NASA MODIS data and applied gradient boosted machines to the lagged data to

forecast future values of vegetation health. We assessed the predictive power of

our model across space, time, and land use categories. Our models have

significantly more predictive power on held-out datasets than simpler baselines.

We constructed an open source tool that predicts per-pixel vegetation health in a

user-specified region of interest at 16-day intervals. This tool is useful in regions

where clouds prevent real-time monitoring of vegetation dynamics.

3 - Profit Optimization For Rare Earth Permanent Magnet Value

Recovery Under Supply And Demand Uncertainties

Rare earth permanent magnets (REPMs) play an essential role in green energy

production and yet face a significant supply risk. To alleviate the risk, value

recovery from end-of-life product is proposed. This research develops an

inventory management strategy for REPM recovery under market supply and

demand uncertainties. A linear programming (LP) model is then developed to

find an upper bound for the proposed strategy. Several scenarios are evaluated

with a hard disk drive (HDD) example. The proposed strategy helps increase the

profit, and the performance is well comparable to the upper bound.
