Parametric model of a lunar base for mass and cost estimates by Peter Eckart 1 edition - first published in Written works: Parametric model of a lunar base for mass and cost estimates. Mass Models In the space industry, mass as been found to be a key cost driver. Thus, the NASA Air Force Cost Model (NAFCOM) estimates space missions cost based on mass. NAFCOM has an extensive database containing parametric cost data and technical information at the group, subsystem and component level for many historical NASA programs.
describes the parametric mass and volume models that are used to assess an aerospace hybrid system design. The design tool utilizes input from the thermodynamic system model and produces component sizing, performance and mass estimates. The software is designed such that theFile Size: KB. The data consist of new building projects, built from to The technique of multiple regression analysis is used to develop the parametric cost estimating model by establishing the cost estimating relationships between the building parameters and the building construction cost.

Parametric model of a lunar base for mass and cost estimates by Peter Eckart; 1 edition; First published in ; Subjects: Lunar bases. In general, the spacecraft seemed to range from $, per kg of bus mass, up to $1, per kg of bus mass.
There were two notable classes of outliers to this range. The two gondola designs cost less than $10, per kg, while the four Mars Ascent Vehicles cost more than $2, per Size: KB. Cost Cost ESAS Cost Analysis Context Current NASA cost projections for the Exploration Vision are based on the Exploration Systems Architecture Study (ESAS) recommended architecture.
The estimates are based on parametric cost models, principally the NASA and Air Force Cost Model (NAFCOM). The cost analysis attempted to be conservative. You would look up the rate in a published estimating book and find that each linear foot of wall in this office would require hours of labor.
If you had 2, linear feet, you would estimate the work at hours (2, x = ). Parametric estimating is successful for often-repeated tasks. model, the cost basis of the model, and its critical components and cost drivers. Developing a Parametric Model for Estimating Process Control Costs Larry R.

The cost model, the data used in the model, and the calibration of the model are cost or pricing data required by TINA.
The Federal Acquisition Regulation does not preclude the use of these techniques, and I see no other regulatory obstacles to the use of parametric estimates wherever appropriate.
The new mathematical model for heat exchanger manufacturing cost estimation is developed and a parametric analysis is carried out showing that an optimal length-to-diameter ratio exists. • Digital models have been common in engineering since the late s but today’s focus on Model-based Engineering goes beyond the use of disparate models • Model-based Engineering moves the record of authority from documents to digital models including M-CAD, E-CAD, SysML and UML managed in a data rich environment • Shifting to model-basedFile Size: 2MB.

Parametric model of a lunar base for mass and cost estimates / Article. Estimates indicate that with MW of electric energy about 3, Mg silicates and Al 2 O 3 in a 50 t facility can be produced. [57,71,72,75,76,77,82,83, 91, 93] The system analysis has shown. 36 / Lunar Base Concepts Program was started in 1, and dozen of studies were carried out by NASA, its contractors, the U.S.
Air Force, and other organizations. A biliography of these studies has been compiled by Lowman (1 ), but only a few main concepts can be summarized in this paper.
The great majority of lunar base concepts proposed in the s were predicated. Open Library is an initiative of the Internet Archive, a (c)(3) non-profit, building a digital library of Internet sites and other cultural artifacts in digital projects include the Wayback Machine, and Sonmez () introduced parametric range estimating of building costs using regression models and bootstrap.
To select parameters which have significant impacts on the cost item, parameters which Author: Rifat Sonmez. A steady-state model for first-order magnitude estimates of lunar base masses is presented. The main focus of the model is the derivation of initial and annual resupply mass estimates for a lunar base at certain development stages.
Deferred Maintenance Guide Parametric Estimating Guide. 6 Facility Condition Index (FCI). This is the weighted sum of condition ratings for all nine-facility systems.
For each Center, the FCI is the weighted average of all nine systems for all Center facilities. ► A parametric cost model is combined with an activity-based cost model. ► The activity-based model can estimate costs at multiple levels of any factory. ► The parametric model predicts the unit cost of future integrally bladed discs.
► The uncertainty in manufacturing operation times is taken into by: Parametric estimates are brilliant at the early and concept stages of the project. In fact, the Parametric Estimating Handbook says that “Early costing cannot be done effectively any other way”.
In many cases the model that you use to do the estimate is actually doing the design of the project for you as it is producing the cost. ‘Water Estimator’ Model ; Commuted Sums Model; Operational Cost Model (OPEX) Time Related Cost Model (CAPEX) Road Upgrade Model Maintenance and Response Model ‘Template Projects’ If you produce estimates at the early or concept stages of the project life-cycle, then you may wish to consider producing a parametric model.A PARAMETRIC COST MODEL FOR ESTIMATING OPERATING AND SUPPORT COSTS OF U.S.
