1 - Cyber Attacker Choices In A Three-way Behavioral Security Game

This study focuses on cyber attackers’ choices in a security game involving

attackers, defenders, and users. An attacker can choose to attack the defenders or

the users. Deterrence is measured by the third option of the attacker - no attack.

Conversely, the defenders and users can select either a standard or enhanced

security level. We conducted a behavioral experiment in which 497 subjects

played as attackers over 30 rounds of the game and were incentivized based on

their performance. Defenders’ and users’ joint strategies were manipulated.

Results indicated that subjects were more likely to hack database when

EV(database) was higher, and were more deterred when both EVs were negative.

2 - Sequential Decisions Following Near Misses

Prior near miss experiences have been identified as a contributing factor in

responses to risks of disasters. Researchers found a near miss event could lead

individuals to interpret the risk as either “vulnerable” or “resilient”, while had no

conclusions on what could lead to different interpretations. The current study

hypothesizes that responses to near miss events are determined by psychological

distance. We conducted a behavioral experiment in which 100 subjects were

exposed to a sequence of 20 events. Results indicated that subjects were less likely

to engage in protective measures when a near miss event is psychological distant

to the decision maker and when more near misses were experienced.

3 - Column Generation For Airline Crew Rostering: Practical

Considerations In A Production System

Andreas Westerlund, Optimization Expert, Jeppesen,

Odinsgatan 9, Gothenburg, 411 03, Sweden,

andreas.westerlund@jeppesen.com

Jeppesen’s crew rostering optimizer is today used by around 40 airlines to

produce monthly schedules for their flying crew. The optimizer allows the user to

configure various kinds of business logic and it solves monthly schedules for

problem instances with above 20k crew-members and 100k activities.

In this presentation we will start by defining the rostering optimization problem

in general. Then we will describe our column generation framework that is used

to deal with it. Finally we will look at the specific problem of having an efficient

fixing process in the presence of high degree of symmetry.

4 - The Internet Of Things: Preliminary Research Results

In this research, we look at the emerging field of the Internet of Things and

develop a research agenda for managerial issues. In addition, we will discuss

research in IoT for preventive maintenance. IoT is shown to be beneficial in

reducing costs and increasing profits.

5 - The Ordered Weighted Average Division

The ordered weighted average division is an aggregation operator that aggregates

a set of divisions providing a parameterized family from the minimum to the

maximum division. The work considers a wide range of particular cases including

the average division, the median division and the weighted average division. It

also develops some further extensions including the weighted ordered weighted

average division and the generalized weighted ordered weighted average division.

This approach can be applied in a wide range of problems dealing with the

aggregation of divisions including decision making and computational

intelligence.

Future of Disease Modeling in Clinical and

Public Health

Sponsored: Computing

Sponsored Session

1 - Pandemic Influenza Preparedness

David Morton, Northwestern University,

david.morton@northwestern.edu

We describe three data-driven optimization models that inform resource

allocation in preparing for an influenza pandemic. In particular, we optimize: the

mix of central and regional stockpiles of ventilators, accounting for stochastic

peak-week demand; the spatial allocation of antivirals, considering under-insured

populations and hard-to-reach locations; and, the spatial allocation of multiple

types of vaccines with differing suitability for each prioritized target population.

We discuss challenges and extensions.

2 - Role Of Operations Research In Chronic Disease Management

Mariel Lavieri, University of Michigan,

lavieri@umich.edu

I discuss past and future challenges encountered in managing chronic diseases.

3 - Mathematical Models for Cancer Screening

Fatih Safa Erenay, University of Waterloo,

ferenay@uwaterloo.ca

My talk will provide an overview of models proposed for the optimal cancer

screening problem from societal and personal perspectives. I will start with the

classical models that schedule screening interventions over a planning horizon,

and describe the evolution of the literature towards more dynamic, partially

observable, and personalized models over examples from colorectal cancer

screening. The talk will also highlight the current challenges and recent trends in

cancer screening literature.

Assets and Structured Hedges in Energy Markets

Severe Incompleteness and Methods for Dealing

with It

Invited: Tutorial

1 - Assets And Structured Hedges In Energy Markets –

Severe Incompleteness And Methods For Dealing With It

Glen Swindle, Scoville Risk Partners, 405 Lexington Avenue,

21st Floor, New York, NY, 12, United States,

glenswindle@scovilleriskpartners.com

Risks in energy markets are inherently high dimensional due to large numbers of

delivery locations and physical attributes, stochastic demand, and seasonality. In

contrast, the number of instruments with sufficient liquidity to support hedging

activities is relatively small, and has never been able to span the set of risks

sustained by market participants. This mismatch has spawned an interesting and

arguably unique set of challenges related to the valuation and hedging of energy

portfolios. Here we will survey examples of such, including variable quantity

swaps, generation and structured asset hedges.
