A methodology for evaluating fleet implications of mission specification changes

Brett, Paul S. 12 January 2015 (has links)
Civil aviation has matured to become a vital piece of the global economy, providing the rapid movement of goods and people to all regions. This has already led to significant growth and expectations of further growth are on the rate of 5% per year. Given the high projected rate of growth, environmental consequences of commercial aviation are expected to rise. To mitigate the increase of noise and emissions, governing bodies such as ICAO and the FAA have established and are considering additional regulation of noise, NOₓ, and CO₂ while the European Union has integrated aviation into their Environmental Trading Scheme. The traditional response to new regulation is to integrate technologies into the aircraft to reduce environmental footprint. While these benefits are positive on the aircraft level, fleet growth is projected to outpace benefits provided by technology alone. To further reduce environmental footprint, a number of mitigation strategies are being explored to determine the impact. One of those strategies involves changing the mission specifications of today's aircraft by reducing range, speed, or payload in an effort to reduce fuel consumption and has been predominantly focused at the vehicle level. This research proposes an approach that evaluates mission specification changes from the aircraft design level up to the fleet level, forecasted into the future, to assess the impact over a number of metrics to fully understand the implications of mission specification changes. The methodology Mission Specifications and Fleet Implications Technique (MS-FIT) identifies stakeholder requirements that will be tracked at either the vehicle or fleet level and leverages them to build an environment that will allow joint evaluation to facilitate increased knowledge about the full implications of mission specification adoption. Additionally laid out is an approach on how to select prospective routes for intermediate stops based on fuel burn and operating cost considerations. Guidance is provided on how to filter down a list of candidate airports to those most viable as well as regions of the world most likely to benefit from intermediate stops. Three sample problems were used to demonstrate the viability of MS-FIT: cruise speed reduction, design mission range reduction, and the combination of speed and range reduction. Each problem was able to demonstrate different implications from the implementation of the different specification changes. Speed reduction can negatively impacts cost while range reduction has consequences to noise at the intermediate airports. The combination of the two draws in negative implications from both even though the environmental benefits are better. Finally, an analysis of some of the assumptions was conducted to examine the sensitivity to the results of speed and range reduction. These include variation in costs, reductions in annual utilization of aircraft, and variation in intermediate stop adoption. Speed reduction is strongly sensitive to increases in crew and maintenance rates while landing fees significantly eat into the benefits of range reduction and intermediate stops. Minor utilization reductions can significantly reduce the viability of speed reduction as the increase in capital costs offset all the savings from fuel reduction while range reduction is a little less sensitive. Intermediate stop variation does not eliminate the benefits of range reduction and even can provide cost savings depending on the design range of the reduced variant but it can have consequences to airport noise to higher traffic airports. With the proposed framework, additional information is available to fully understand the implications with respect to fuel burn, NOₓ emissions, operating cost, capital cost, noise, and safety. This can then inform decision makers on whether pursuing a particular mission specification strategy is advantageous or not.

Advances in capital replacement modelling with applications

Bouamra, Omar January 1996 (has links)
This thesis addresses the capital replacement modelling problems associated with a mixed, or inhomogeneous, fleet and also takes account of the fleet size problem. Applications considered relate to a fleet of buses and a fleet of medical equipment. The initial chapters introduce the notion of capital replacement modelling and review previous work in the field, as well as reviewing the fleet size problem. Replacement policies are also put in the context of the fleet rather than the context of a 'typical plant'. In the third chapter, we present our first attempt to model capital replacement with variable fleet size over a finite planning horizon. A two cycle model is developed in which the notion of penalty cost for breakdown is introduced. This cost is incurred when demand is not met. To take account of the cost of unmet demand, a simple failure model for plant is proposed. The replacement model is applied to a fleet of ventilators in an intensive care unit of a hospital. In the fourth chapter we develop various models for the case of replacement of a sub-fleet within a mixed fleet. These models themselves have variable finite planning horizon of variable length and build on developments described earlier in the thesis. Other aspects such as the increased cost of sub-optimal policy due to delayed replacement, smaller replacement sub-fleet etc. are also considered. The models developed in chapter 4 are applied, in the following chapter, to a fleet of buses operated by a Malaysian inter-city bus company. Sensitivity analysis on different factors is also carried out. Finally the sensitivity of optimal decision policy to the choice of the replacement model is described in the context of the bus application.

The geology of the Cairnsmore of Fleet granite and its environs, southwest Scotland

Cook, David R. January 1976 (has links)
The thesis is divided into three parts relating to (i) the sedimentary rocks, (ii) the granite and minor intrusive rocks and (iii) the Fleet orefield. The Sedimentary successions around the Cairnsmore of Fleet pluton are divided into two new formations; the Craignell and Knockeans Formations. The former is sub-divided into three facies based upon a geochemical classification of greywackes undertaken using cluster analysis. Facies boundaries within the Craignell Formation and interformational boundaries between this formation and the underlying Moffat Shales and the younger Knockeans Formation are all probably diachronous. Tectonically derived structures within the sedimentary rocks are correlated with those reported from areas elsewhere within the Southern Uplands. Certain structures are, however, unique to this area and some may be related to the emplacement of the Fleet pluton. Mineralogical zones within the extensive thermal aureole surrounding, the granite are described and correlated with previously published facies of contact metamorphism: albite-epidote hornfels, hornblende hornfels and K-feldspar-cordierite hornfels facies. Petrological facies within the granite are described and the classification thus produced endorsed geochemically with the aid of cluster analysis. Chemical trends in separated minerals, are correlated with bulk chemical variation in the granite which is outlined using correlation, regression and trend surface analyses. Geo-chemical and petrological data are compared with published experimental mineralogical studies. Minor intrusive rocks are similar in composition to those occurring throughout Galloway with two notable exceptions of more basic composition. The chemistry of the minor of the Fleet pluton are described the western margin to the Fleet pluton are described in detail for the first time. A distinct mineralogical zoning pattern is spatially related to the granite and consists of an inner zone within the pluton and generally close to the contact in the country rocks, containing dominant chalco-pyrite, pyrrhotite, pyrite and high temperature ores such as pentlandite and arsenopyrite with a quartzose gangue. Outer zones contain veins of sphalerite and mixed carbonate and quartz gangue, and give way to an outermost zone of galena with carbonate and barytes gangue. Geochemical studies on separated ore minerals has enabled the distinction of ores from particular zones and give an indication of their relative temperatures of formation. Wallrock alteration is described and is generally consistent in its characteristics with the changing mineralogy of the vein deposits. The ore deposits are related to the geophysically predicted granite batholith beneath the Southern Uplands, but more specifically to the Fleet pluton. The mineralogy and geochemistry of the deposits are consistent with this, but geochronological studies from other areas suggest that the ores may be at least 40 my younger than the granite. A hypothesis for the origin of the hydrothermal deposits is presented and is based upon data outlined above.

Fleet Introduction Project for the United States Navy's Next Generation Bathythermograph Recorder System

Moss, Larry Reynolds 25 April 1997 (has links)
The following report presents the preliminary design and prototype development phase of a technology insertion program implemented by this author to extend the service life and to improve the performance of the United States Navy's Bathythermograph Data Recorder System onboard Submarines (AN/BQH-7) and Surface Ships (AN/BQH-7A). The performance upgrade will increase the Fleet User's ability to measure sonar performance and will provide more accurate salinity measurements used for submarine ballasting and control. This project is unique not necessarily because Commercial-off-the-Shelf (COTS) and Non-Developmental Item (NDI) componentry is being used but because the focus is on developing a systems engineering process model for (1) the implementation of COTS and NDI technologies in an open systems architecture environment, (2) a maintenance, sparing, and life cycle support model for COTS and NDI programs, and (3) a periodic technology insertion plan for keeping pace with COTS and NDI technology advances and configuration changes. It is intended that this report be used in the future as a good example of the successful implementation of Acquisition Reform and DoD 5000.2B initiatives. / Master of Science
