3 - Parallel Computing For The Optimization Of A Large-scale

Dynamic Network - The Internet Of Hearts

Rapid advancements of mobile computing provide an unprecedented opportunity

to empower a next generation mobile health system - the internet of heart (IoH).

The IoH embeds patients into a dynamic network and reveals the change of

patient’s status through network variations. However, it poses a great challenge

for real-time recognition of disease patterns when large number of patients are

involved in IoH. This study develops a novel scheme to optimize the network in a

parallel, distributed manner, thereby improving the the efficiency of computation.

Experimental results show that the developed scheme is effective and efficient for

realizing smart connected healthcare in large-scale IoH contexts.

4 - Control Policies For Iot Manufacturing Systems: A Two Stage

Stochastic Approach

We consider a smart manufacturing setting where materials and machines are

part of an IoT. A two-stage stochastic model is formulated to determine tool

replacement and processing speed decisions based on the availability of the job

arrival as well as machine health and processing status information. Stage 1 uses a

Lyapunov method to cluster jobs for throughput optimization, and Stage 2

employs a stochastic scheduling algorithm to minimize cycle times. We also

analyze the effectiveness of this approach using extensive numerical testing.

1 - Performance Feedback In Competitive Product Development

Daniel P Gross, Harvard Business School,

dgross@hbs.edu

Performance feedback is ubiquitous in competitive settings where new products

are developed. This paper introduces a tension between incentives and

improvement in performance evaluation. Using a sample of four thousand

commercial logo design tournaments, I show that feedback reduces participation

but improves the quality of submissions, with an ambiguous effect on high-

quality output. To evaluate this tradeoff, I develop a procedure to estimate agents’

effort costs and simulate counterfactuals under alternative feedback policies. The

results suggest that feedback on net increases the number of high-quality ideas

produced and may thus be desirable for a principal seeking innovation.

Employee ideas are a valuable starting point to improve operational efficiency. We

empirically investigate how moves between problems and sites affect the

innovation value created by employee ideas for the organization. We document

that the dynamic effects of problem switches differ fundamentally from the effects

of site switches: The innovation outcomes of problem switching employees follow

a concave inverse u-shaped pattern, whereas the innovation outcomes of site

switching employees follow a convex u-shaped pattern over time. We discuss

implications for theory.

This paper analyzes the organization of multiple innovation contests in which

organizers post problems to a group of agents, and elicit innovative solutions. We

compare the contest organizers’ payoffs when they organize multiple contests

simultaneously or when they compete with other contest organizers for the effort

of agents towards solving their problems. We show that depending on problem

structure, more intense competition among organizers and organizing multiple

contests may harm or, counter-intuitively, benefit each organizer. Our findings

explain why organizers find it beneficial to hold multiple contests or organize

similar contests with their competitors simultaneously.

1 - Integrating Data Science In Statistical Practice And Analytics

Steven B Cohen, RTI International, 701 13th Street NW,

The field of data science has served to rapidly expand the knowledge base and

decision-making ability through the combination of seemly disparate and diverse

sources of information and content, which include survey and administrative

data, social, financial and economic micro-data, and content from mobile devices,

the internet and social media. Other attributes of data science include data

visualization; predictive, mathematical and simulation modeling; use of Bayesian

methods, machine learning; GIS and geospatial analytics and Big Data

technologies. In this presentation, attention is given to demonstrate the capacity

of data science to enhance study designs and predictive analytics.

Developing A Scalable Framework For The Future

Michael Chuang, State University of New York, 1 Hawk Drive,

NGS analysis presents a domain for biomedical and information technology

professionals to explore. Due to the large amount of data involved and various

constraints of technologies, we delineate issues to consider to develop a

framework using parallel computing and NoSQL database service to greatly

reduce the required time under less infrastructure investments while achieving

satisfactory accuracy.

3 - Five Steps To Big Data Analytics

Analytics has been categorized as descriptive, predictive and prescriptive.

However, much many challenges lie in the data preparation. Also, analytics is

typically concerned about prediction rather than explaining, leaving manager’s to

question whether to trust results. Hence, data preparation and causal inference

are two important steps in analytics at the beginning and end of an analytics

project life cycle.

We investigate how public transportation planning affects the economic growth

and social development in the urban areas, especially the economic enhancement

zones in US cities. We build visualization tools to help decision makers

understand the impact of future planning and issues of existing system.

This study develops a two-stage stochastic mixed-integer programming model to

manage sustainable pellet processing depots under feedstock supply uncertainty.

The proposed optimization model not only minimizes cost but also mitigates

emissions from the supply chain network. We develop a hybrid decomposition

algorithm that combine Sample average approximation with an enhanced

Progressive Hedging (PH) algorithm. Mississippi and Alabama are selected for

testing ground of this model. The results of the analysis reveal promising insights

that could lead to recommendations to help decision makers to achieve a more

cost-effective environmentally-friendly supply chain network.
