Nondimensionalization is the partial or full removal of physical dimensions from an equation involving physical quantities by a suitable substitution of variables.This technique can simplify and parameterize problems where measured units are involved.
Tactically, this has been accomplished by using the various PCM techniques and tools discussed above in a predictive way. That is, the tools are used to estimate a cost that is used as an absolute value for what a cost should be, or to relatively evaluate the cost of one design or manufacturing process or supplier versus another.
Cost of transport is the efficiency in moving from one place to another; Elasticity is the measurement of the proportional change of an economic variable in response to a change in another; Basic reproduction number is a dimensionless ratio used in epidemiology to quantify the transmissibility of an infection.

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.
An important part of standard cost accounting is a variance analysis, which breaks down the variation between actual cost and standard costs into various components (volume variation, material cost variation, labor cost variation, etc.) so managers can understand why costs were different from what was planned and take appropriate action to ...
Scale analysis anticipates within a factor of order one when done properly, the expensive results produced by exact analyses. Scale analysis rules as follows: Rule1-First step in scale analysis is to define the domain of extent in which we apply scale analysis. Any scale analysis of a flow region that is not uniquely defined is not valid.
The cost driver is a factor that creates or drives the cost of the activity. For example, the cost of the activity of bank tellers can be ascribed to each product by measuring how long each product's transactions (cost driver) take at the counter and then by measuring the number of each type of transaction.
