Level of Repair Analysis. Level of Repair Analysis ( LORA) is used as an analytical methodology used to determine where an item will be replaced, repaired, or discarded based on cost considerations and operational readiness requirements. For a complex engineering system containing thousands of assemblies, sub-assemblies, components, organized ...
A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead. Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units. Any difference between applied overhead and the amount of overhead actually incurred is called over- or under-applied overhead.
The point of total assumption ( PTA) is a point on the cost line of the profit-cost curve determined by the contract elements associated with a fixed price plus incentive-Firm Target (FPI) contract above which the seller effectively bears all the costs of a cost overrun. The seller bears all of the cost risk at PTA and beyond, due to a dollar ...
Equivalent annual cost. In finance, the equivalent annual cost ( EAC) is the cost per year of owning and operating an asset over its entire lifespan. It is calculated by dividing the negative NPV of a project by the "present value of annuity factor": where r is the annual interest rate and. t is the number of years.
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate.

Mean time to repair (MTTR) is a basic measure of the maintainability of repairable items. It represents the average time required to repair a failed component or device. [ 1 ] Expressed mathematically, it is the total corrective maintenance time for failures divided by the total number of corrective maintenance actions for failures during a ...
The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [5] The LCOE is an estimation of the cost of production of energy, thus it tells nothing about the price for consumers and is most meaningful from the investor’s point of view.
