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.
Some examples of indirect costs and their drivers are: indirect costs for maintenance, with the possible driver of this cost being the number of machine hours; or the indirect cost of handling raw-material cost, which may be driven by the number of orders received; or inspection costs that are driven by the number of inspections or the hours of ...
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.
The difficulty measure is related to the difficulty of the program to write or understand, e.g. when doing code review. The effort measure translates into actual coding time using the following relation, Time required to program: = seconds
The following examples include fictional numbers, lack complexity concerning the cost drivers and are merely used to display the method of cost breakdown analyses. Transportation and corrugated boxes are very illustrative examples as they allow a simple break down of the total cost into the single cost drivers.
For example, the arithmetic complexity of the computation of the determinant of a n×n integer matrix is () for the usual algorithms (Gaussian elimination). The bit complexity of the same algorithms is exponential in n, because the size of the coefficients may grow exponentially during the computation.
The minimum-cost flow problem (MCFP) is an optimization and decision problem to find the cheapest possible way of sending a certain amount of flow through a flow network.A typical application of this problem involves finding the best delivery route from a factory to a warehouse where the road network has some capacity and cost associated.
In the context of pharmacoeconomics, the cost-effectiveness of a therapeutic or preventive intervention is the ratio of the cost of the intervention to a relevant measure of its effect. Cost refers to the resource expended for the intervention, usually measured in monetary terms such as dollars or pounds. The measure of effects depends on the ...
