Parametric analysis is the process of determining the highly predictive equations necessary for parametric estimating. Together, parametric estimating and parametric analysis constitute parametric cost analysis. Johnston (), probably the first book on parametric cost analysis, provides foundational theory, methods, and results from case. Parametric Modeling Using High-Level Objects (HLOs) At the core, there are fundamentally three approaches to estimating: Bottom up 3, in which the project is decomposed to individual components that can be estimated by some other means, often expert judgment for labor.; Analogy, in which historic budgets or actual expenditures are used as a basis for current estimates.

The technique used is a parametric cost system, not the square foot cost system used by most who quote an up-front building cost. To help calculate the parameter quantities and price them as quantified, this book comes with 5 electronic templates to calculate program scope; i.e. – space, configuration, HVAC loads, plumbing and electrical. Parametric modeling can be quite complex and needs to be fed with a lot of data, and that's why it's only used by large governmental agencies (such as the NASA). answered 8 years ago by MaplePM (46, points) – edited 8 years ago by MaplePM.

Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms. schedule where the spacecraft development phase takes place within years or less. The development team staffs up much faster, there is widespread use of behavioral and cross-cutting computerized models (which Operations Cost/Yr Vs Launch Year will reduce the need for work force intensive change control boards, etc.), and there is a.

Additional Physical Format: Online version: Large, Joseph P. Development of parametric cost models for weapon systems. Santa Monica, Calif.: Rand Corp., Statistical cost models are widely used in the Department of Defense for estimating the cost of next-generation weapon systems.

This paper presents a brief survey of the evolution of such models from the post-World War II period to the present time. Cost Engineering Vol. 43/No. 2 FEBRUARY 31 A parametric cost model is an ex-tremely useful tool for prepar-ing early conceptual estimates, when there is little technical data or engineering deliverables to pro-vide a basis for using more detailed esti-mating methods.

However, according to the DoD/DoA, there are currently no real-world examples of parametric models for estimation of sediment treatment project costs (Myers, ).

If Cheops thought about cost at all when building the Great Pyramid he would have In the Air Force published Source Book of World War II Basic Data: Airframe Industry [11, which presented a number.

Currently, in equipment system cost estimation, parametric models are applied widely. In this paper, on the base of the concrete analysis on the adopted cost estimation model, the discussion was.

The development of a parametric model for the variable portion of the Cost Per Flying Hour (CPFH) of an ‘unknown’ aircraft platform and its application to diverse types of fixed and rotary wing aircraft development programs (FA, Su, Dassault Rafale, T-X candidates, AW, Airbus RACER among others) is presented.

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.

Cost of Software Development The Air Force faces a large reduction in defense spending. Concurrent with that reduction is a continued requirement for the development of new weapon systems to replace aging and hard to maintain older systems.

A major portion of. Comparisons with other classes of models. Parametric models are contrasted with the semi-parametric, semi-nonparametric, and non-parametric models, all of which consist of an infinite set of "parameters" for distinction between these four classes is as follows: [citation needed] in a "parametric" model all the parameters are in finite-dimensional parameter spaces.

Parametric estimating is an acceptable method, according to the Federal Acquisition Regulation (FAR), for preparing proposals based on cost or pricing data or other types of data. The primary benefit from developing a parametric estimating capability is a more streamlined estimating and proposal process for both Industry and Government.

The primary goal of Parametric Modeling with Creo Parametric is to introduce the aspects of Solid Modeling and Parametric Modeling.
