Cyber This, Cyber That...So What?, Eric D. Trias, Bryan Bell [*] 2010 Air Force Institute of Technology

Cyber This, Cyber That...So What?, Eric D. Trias, Bryan Bell [*]

Faculty Publications

This article endorses the idea that cyber operations may be conducted in all war-fighting domains: air, space, cyberspace, land, and sea. In addition, despite the immaturity of cyberspace operational doctrines, the doctrines from air and space remain relevant and applicable to the cyberspace domain. Cyber operations are just another set of tools in the commander's toolbox. Although cyber operations have distinct ways of achieving effects, from an Air Force perspective they are similar too the air and space operations that support air and space (and cyberspace) functions. Known and established cyber operations provide war fighters with viable options to kinetic …


Non Bayesian Conditioning And Deconditioning, Jean Dezert, Florentin Smarandache 2010 University of New Mexico

Non Bayesian Conditioning And Deconditioning, Jean Dezert, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper, we present a Non-Bayesian conditioning rule for belief revision. This rule is truly Non-Bayesian in the sense that it doesn’t satisfy the common adopted principle that when a prior belief is Bayesian, after conditioning by X, Bel(X|X) must be equal to one. Our new conditioning rule for belief revision is based on the proportional conflict redistribution rule of combination developed in DSmT (Dezert-Smarandache Theory) which abandons Bayes’ conditioning principle. Such Non-Bayesian conditioning allows to take into account judiciously the level of conflict between the prior belief available and the conditional evidence. We also introduce the deconditioning problem …


Effect Of Time Pressure And Task Uncertainty On Human Operator Performance And Workload For Autonomous Aerial Vehicle Missions, Trevor Petersen 2010 Embry-Riddle Aeronautical University

Effect Of Time Pressure And Task Uncertainty On Human Operator Performance And Workload For Autonomous Aerial Vehicle Missions, Trevor Petersen

Master's Theses - Daytona Beach

Unmanned aircraft systems (UAS) are being utilized at an increasing rate for a number of military applications. The potential for their use in the national airspace is also of interest to the Federal Aviation Administration, but there are some concerns about the safety of flying unmanned aircraft. The role of a UAS operator differs from that of a pilot in a manned aircraft, and this new role creates a need for a shift in interface and task design in order to take advantage of the full potential of these systems. This study examined the effect of time pressure and task …

Simulation Analysis Of High Velocity Maintenance For The B-1b, Anson R. Park 2010 Air Force Institute of Technology

Simulation Analysis Of High Velocity Maintenance For The B-1b, Anson R. Park

Theses and Dissertations

This thesis explores the impact that High Velocity Maintenance (HVM) will have on aircraft availability rates for the B-1B by examining the proposed changes to the field maintenance and supply processes for the two B-1B squadrons of the 28th Bombardment Wing located at Ellsworth AFB, SD. There is a significant restructuring of depot level maintenance planned with the implementation of HVM, and the impact that this will have on base-level operations is important to determine, for it will provide insight as to whether or not HVM will be a feasible program with a high probability of successfully improving B-1B aircraft …


An Exploration Of The Effects Of Maintenance Manning On Combat Mission Readiness Utilizing Agent Based Modeling, Adam S. MacKenzie 2010 Air Force Institute of Technology

An Exploration Of The Effects Of Maintenance Manning On Combat Mission Readiness Utilizing Agent Based Modeling, Adam S. Mackenzie

Theses and Dissertations

Agent based models have been shown to be powerful tools in describing processes and systems centered on individual behaviors and local interactions (i.e. “bottom-up”) between specific entities. Current application areas tend to be focused within the business and social science arenas, although their usefulness has been demonstrated in the modeling of various chemistry and physics-based systems. Conversely, many highly process-oriented systems, such as manufacturing environments, tend to be modeled via “top-down” methods, including discrete or continuous event simulations among others. As a result, potentially critical attributes of the entities or resources modeled with these methods (spatial properties, “learning curve” or …


A Simulation Based Methodology To Examine The B-1b'S An/Alq-161 Maintenance Process, Ricardo R. Garza 2010 Air Force Institute of Technology

A Simulation Based Methodology To Examine The B-1b'S An/Alq-161 Maintenance Process, Ricardo R. Garza

Theses and Dissertations

The B-1 Bomber is the Air Force’s only supersonic, conventional-only strike platform. This thesis looks at the maintenance procedures associated with the defensive electronic counter measure (ECM) system on the B-1B, designated the AN/ALQ-161. Computer simulation of the current line-replaceable-unit maintenance network for Ellsworth AFB and Dyess AFB is modeled. In addition, two hypothetical repair networks are proposed and analyzed. This research considers the applicability of this type of computer simulation, using ARENA software to study the AN/ALQ-161 repair system. The contribution of this research is a discrete simulation methodology specific to the AN/ALQ-161 LRU repair line. Two response variables …

Fusion Of Imprecise Qualitative Information, Florentin Smarandache, Xinde Li, Xianzhong Dai, Jean Dezert 2010 University of New Mexico

Fusion Of Imprecise Qualitative Information, Florentin Smarandache, Xinde Li, Xianzhong Dai, Jean Dezert

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper, we present a new 2-tuple linguistic representation model, i.e. Distribution Function Model (DFM), for combining imprecise qualitative information using fusion rules drawn from Dezert-Smarandache Theory (DSmT) framework. Such new approach allows to preserve the precision and efficiency of the combination of linguistic information in the case of either equidistant or unbalanced label model. Some basic operators on imprecise 2-tuple labels are presented together with their extensions for imprecise 2-tuple labels. We also give simple examples to show how precise and imprecise qualitative information can be combined for reasoning under uncertainty. It is concluded that DSmT can deal …

Fusion Of Sources Of Evidence With Different Importances And Reliabilities, Florentin Smarandache, Jean Dezert, J.M. Tacnet 2010 University of New Mexico

Fusion Of Sources Of Evidence With Different Importances And Reliabilities, Florentin Smarandache, Jean Dezert, J.M. Tacnet

Branch Mathematics and Statistics Faculty and Staff Publications

This paper presents a new approach for combining sources of evidences with different importances and reliabilities. Usually, the combination of sources of evidences with different reliabilities is done by the classical Shafer’s discounting approach. Therefore, to consider unequal importances of sources, if any, a similar reliability discounting process is generally used, making no difference between the notion of importance and reliability. In fact, in multicriteria decision context, these notions should be clearly distinguished. This paper shows how this can be done and we provide simple examples to show the differences between both solutions for managing importances and reliabilities of sources. …

Individualized Cognitive Modeling For Close-Loop Task Mitigation, Guangfan Zhang, Roger Xu, Wei Wang, Jiang Li, Tom Schnell, Mike Keller, Thomas E. Pinelli (Ed.)

Electrical & Computer Engineering Faculty Publications

An accurate real-time operator functional state assessment makes it possible to perform task management, minimize risks, and improve mission performance. In this paper, we discuss the development of an individualized operator functional state assessment model that identifies states likely leading to operational errors. To address large individual variations, we use two different approaches to build a model for each individual using its data as well as data from subjects with similar responses. If a subject's response is similar to that of the individual of interest in a specific functional state, all the training data from this subject will be used …
