Assessing the Impact of Development Disruptions & Dependencies in Analysis of Alternatives of System-of-Systems

Co-investigator: Dr. Karen Marais (AAE)
Sponsor: U.S. Department of Defense, through System Engineering Research Center (SERC)

Synopsis: The objective is to develop and test methods that quantify the impact of system interdependencies and other architecture features in the context of SoS capability development. A variety of methods are investigated towards the goal of navigating the decision space that simultaneously considers the potential positive impacts of interdependencies (e.g., SoS capability) and negative impacts (e.g. risk-likelihood and consequences of disruption). The tools are constructed within an analytic workbench framework that would support tradeoff analysis on cost, performance and resilience, among other metrics, while considering the effect of interdependencies.

BADA files for these vehicles are developed with the help of NASA's Flight Optimization System (FLOPS) and other in-house, integrated aircraft sizing tools.

   
       
 

Agent-Based Enhanced C2BMC Architecture
Co-investigators: Saurabh Bagchi, ECE & Stephen Heister, AAE
Sponsor: Missile Defense Agency

Synopsis: The Missile Defense Agency's mission is to "develop and field an integrated Ballistic Missile Defense System (BMDS) capable of providing a layered defense for the homeland, deployed forces, friends, and allies against ballistic missiles of all ranges in all phases of flight." The present research contract is aimed at achieving a significant improvement in the performance of the Command and Control, Battle Management and Communications (C2BMC) element within the BMDS via disruptive technologies and/or concepts. At maturity, this project will use agent-based models to show the capability of the BMDS to handle large raid sizes with minimal leakage and cost using fixed or adaptive C2BMC architectures.

A Concept for Flexible Operations and Optimized Traffic into Metroplex Regions
Co-investigators: Dr. Landry (IE), Dr. Sun (AAE), and Dr. Wieland (Intelligent Automation Inc.)
Sponsor: NASA Langley Research Center

Synopsis: The objective is to determine whether this new concept of flight plan (Flexible operations and optimized traffic into Metroplex regions) has operational value in the future. This project combines FFS (Flexible Flight Selection Model), LTV (Linear Time Varying Optimization Model), McTMA (Multi-center Traffic Management Advisor Model), and ACES (Airspace Concepts Evaluation System). This concept should allow the NAS to maximize Metroplex airport throughput, increase its resiliency to disruptions, allow maximum flexibility for users, and degrade gracefully under adverse conditions.

Epidemiological Studies Employing Network Theory & SoS Framework
Co-investigators: Prof. Larry Glickman & Prof. George Moore, Department of Veterinary Pathobiology

Synopsis: The recent occurrence of bird-flu has caused enough agitation and concern among all the nations and has spurred massive research into not only developing vaccines and medications but also epidemic and pandemic rescue operations. The development of successful counter measures not only needs installation of massive infrastructure and management of the logistics therein but also novel approaches based on sophisticated theories concerning both the spread of a potential epidemic and the associated socio-political and socio-economic implications. With rapid globalization underway, the control of epidemics can be classified into an SoS problem. A pilot study has been initiated in collaboration with the department of Veterinary Pathobiology to map the spread of bird-flu using the theories of social-network analysis to examine a hypothetical scenario of the incidence of bird-flu in the Marion County of Indiana. The results from this pilot study are then sought to form important input to the bigger issue of developing an action plan.

Serious Games

Co-Investigators: Prof. Sean Brophy, ENE & Prof. David Ebert, ECE
Sponsor: Purdue Discovery Learning Center

Synopsis: The objective is to transform AAE Introduction to Aerospace Design, our sophomore design course, into a semester-long, team-based, multi-player online Serious Game. The game centers on a "Corporate Simulation" theme, in which learners must pursue quests to obtain knowledge in the midst of competition and collaboration with others. The research emphasis of the project is on engineering education, how students learn to design collaboratively and in distributed settings. The long-term goal is for the Game to be extensible and scalable: to educational levels (K-12 through senior UG) and domain applications (other engineering design courses, and corporate training).

Air Force Supply Network and Analysis and Optimization

Synopsis: The Center for Security Policy review of the MCS states that "if the armed forces are to remain capable of successfully performing the multitude of missions levied upon them by our leaders they must have 'among other things'-a dependable and sufficient airlift capacity." However, the current USAF mobility network is unable keep this capability in light of the increasing airlift demands placed upon it for troop transport. Thus, the objective of this research is to model and simulate a supply chain network that is robust and flexible; with both the resources (aircraft, base locations, infrastructure layouts) and the network in which it will operate must be designed and optimized simultaneously.
