Modeling and Analyzing Inter-Satellite Relative MotionTBMG-5219712/01/2024
From a mission operations perspective, swarms pose a planning challenge due to the limited scalability of ground operations. The capabilities needed to support swarm missions go beyond operator-specified geometry, alignment, or separation, but also crosslink communication with maintaining position in the formation. To address scalable control of orbital dynamics, NASA Ames Research Center has patented Swarm Orbital Dynamics Advisor (SODA) — a solution that accepts high-level configuration commands and provides the orbital maneuvers needed to achieve the desired type of swarm relative motion.

Traceability Verification with respect to DO-178 and AS 91152022-26-120005/26/2022
As many business analysts say, following Aerospace guideline DO-178 for developing aerospace software products is not cheap and it comes with a cost. That too, experts say DO-178C can increase the cost of the product above DO-178B, which already increased costs by around 20-40%. So, to keep the cost under control, it is definitely important that we need to develop the software product by following various technical methodology and processes rigorously. DO-178 relies upon significant verification (reviews, tests, and analysis) to assess product quality. However, product quality comes from a quality process, design, and implementation, not just from testing. Performing Traceability verification is one such approach to determine if the requirements are correctly and completely captured, designed, implemented and verified. In this paper we discuss the various phases of the project lifecycle where the Traceability verification needs to be performed. These Traceability verifications are a

Estimation of Fuel Consumption and CO 2 Emissions of Car Travel in Transportation Planning: The Lazio Region Case Study2019-24-025210/07/2019
In transportation planning studies, equilibrium traffic flows and speeds are commonly post-processed to provide estimates of fuel consumption and CO2 emissions. CO2 emissions are tightly linked to fuel consumption. Two methods for this estimation are compared in the paper, depending on whether the fuel consumption factor (per vehicle-km travelled) of different vehicle classes is independent (first method) or dependent (second method) on the average speed of the individual links of the road network. Fuel consumption and emission factors are from the COPERT database by the European Environment Agency. The analysis restricts to cars. The results of the Lazio region case study (Italy) are indicative that the magnitude of the bias that affect the first method compared with the more detailed second method can be as high as 20%.

Multi-Domain Command and Control (MDC2)18AERP02_0102/01/2018
Changing the Face of Modern Warfare We are at an inflection point in the evolution of warfare. While technology is rapidly increasing pace, it is also creating an expansion into multiple, parallel domains, and giving enemy forces more options for both disruption and defense. Technology advances are a key factor to successes spanning the spectrum from humanitarian efforts to complex anti-access/area-denial environments. However, technology is only an enabler, and mindsets must change to allow the technology to be a tool for success, and not ignored due to antiquated doctrine, policies, and guidance. MDC2 represents a new way of thinking about how to coordinate force employment across multiple warfighting domains, and bridging capabilities from old and new technologies. MDC2 itself is not a new technology, but rather a mindset for operational planning, and creating systems that can more easily talk and coordinate with each other.

A Potential Field Based Lateral Planning Method for Autonomous Vehicles2016-01-187409/14/2016
As one of the key technologies in autonomous driving, the lateral planning module guides the lateral movement during the driving process. An integrated lateral planning module should consider the non-holonomic constraints of a vehicle, the optimization of the generated trajectory and the applicability to various scenarios. However, the current lateral planning methods can only meet parts of these requirements. In order to satisfy all the performance requirements above, a novel Potential Field (PF) based lateral planning method is proposed in this paper. Firstly, a PF model is built to describe the potential risk of the traffic entities, including the obstacles, road boundaries and lines. The potential fields of these traffic entities are determined by their properties and the traffic regulations. Secondly, the planning algorithm is presented, which comprises three modules: state prediction, state search and trajectory generation. The state prediction is realized through the lateral

Utilizing Discrete Event Simulation for Schedule Analysis: Processes and Lessons Learned from NASA's GOPD Integrated Timeline Model2015-01-239709/15/2015
In planning, simulation models create microcosms, small universes that operate based on assumed principles. While this can be powerful, the information it can provide is limited by the assumptions made and the designed operation of the model. When performing schedule planning and analysis, modelers are often provided with timelines representing project tasks, their relationships, and estimates related to durations, resource requirements, etc. These timelines can be created with programs such as Microsoft Excel or Microsoft Project. There are several important attributes these timelines have; they represent a nominal flow (meaning they do not represent stochastic processes), and they are not necessarily governed by dates or subjected to a calendar. Attributes such as these become important in project planning since timelines often serve as the basis for creating schedules. Simulation techniques such as discrete event simulation (DES) provide the opportunity to introduce variability into

Advantages of Simulation Based Reliability Growth Planning2015-01-043904/14/2015
The current reliability growth planning model used by the US Army, the Planning Model for Projection Methodology (PM2), is insufficient for the needs of the Army. This paper will detail the limitations of PM2 that cause Army programs to develop reliability growth plans that incorporate unrealistic assumptions and often demand that infeasible levels of reliability be achieved. In addition to this, another reliability growth planning model being developed to address some of these limitations, the Bayesian Continuous Planning Model (BCPM), will be discussed along with its own limitations. This paper will also cover a third reliability growth planning model that is being developed which incorporates the advantageous features of PM2 and BCPM but replaces the unrealistic assumptions with more realistic and customizable ones. The internal workings of this new Tank Automotive Research Development and Engineering Center (TARDEC) developed simulation-based model will be delved into with a focus

Women in vehicle engineering14AUTD09_0109/16/2014
Females have made significant progress cracking the predominantly male domain of automotive engineering. They're now chief engineers, VPs, even a CEO. But why are there still so few of them? Cindy Hess rocketed through the Auburn University College of Engineering in just three years. Graduating as an electrical engineer in 1977, she turned down job offers from aerospace giants Boeing and General Dynamics to join Chrysler Electronics as its first-ever female engineer. In 1981, she was assigned to the automaker's Highland Park, MI, complex. “I was the sixth woman within a workforce of about 6000 engineers at Chrysler at the time,” she recalled. “And it's incredible when I think about what we had to endure to do our jobs in those days.”

Flexible Design and Operation of a Smart Charging Microgrid2014-01-071604/01/2014
The reliability theory of repairable systems is vastly different from that of non-repairable systems. The authors have recently proposed a ‘decision-based’ framework to design and maintain repairable systems for optimal performance and reliability using a set of metrics such as minimum failure free period, number of failures in planning horizon (lifecycle), and cost. The optimal solution includes the initial design, the system maintenance throughout the planning horizon, and the protocol to operate the system. In this work, we extend this idea by incorporating flexibility and demonstrate our approach using a smart charging electric microgrid architecture. The flexibility is realized by allowing the architecture to change with time. Our approach “learns” the working characteristics of the microgrid. We use actual load and supply data over a short time to quantify the load and supply random processes and also establish the correlation between them. The quantified processes are then used

New Metrics to Assess Reliability and Functionality of Repairable Systems2013-01-060604/08/2013
The classical definition of reliability may not be readily applicable for repairable systems. Commonly used concepts such as the Mean Time Between Failures (MTBF) and availability can be misleading because they only report limited information about the system functionality. In this paper, we discuss a set of metrics that can help with the design of repairable systems. Based on a set of desirable properties for these metrics, we select a minimal set of metrics (MSOM) which provides the most information about a system, with the smallest number of metrics. The metric of Minimum Failure Free Period (MFFP) with a given probability generalizes MTBF because the latter is simply the MFFP with a 0.5 probability. It also generalizes availability because coupled with repair times it provides a clearer picture of the length of the expected uninterrupted service. Two forms of MFFP are used: transient and steady state. Other metrics of cost, planning horizon, number of failures within the planning

Planning Complex Sequences Using Compressed RepresentationsTBMG-554708/01/2009
A method that notably includes the use of compressed representations interleaved with non-compressed (time-line) representations of a general scheduling problem has been conceived as a means of increasing, by orders of magnitude, the speeds of computations needed for scheduling complex sequences of activities that include cycles wherein subsets of the activities and/or sequences are repeated. The method was originally intended to be used in scheduling large campaigns of scientific observations by instruments aboard a spacecraft. A typical such campaign could include observations of millions of targets, many observations to be made during long repeated passes. The method would also be useful on Earth for scheduling complex sequences of activities that include cycles.

Design for Manufacturing in Automated Aircraft Assembly Machining2008-01-230309/16/2008
The lack of aircraft fastener object standardization in CATIA has forced many aircraft OEMs and suppliers to custom build and maintain their own fastener definition methods. Content, state and consistency of those Fastener Definitions make a huge difference to subsequent processes, especially in an extended enterprise environment, which becomes more and more common in aircraft manufacturing (e.g. 787). Cenit has been developing an application, which is fully integrated in CATIA/DELMIA V5. It provides design and manufacturing engineers with V5 standard fastener objects and an intuitive workbench to add into a V5 assembly. This paper discusses an industry based end-to-end solution for fastener definition, assembly planning and offline programming contained within a single user interface, which maintains full data associativity in a PLM environment.
