  2. Chemical plant cost indexes - Wikipedia

    en.wikipedia.org/wiki/Chemical_plant_cost_indexes

    A cost index is the ratio of the actual price in a time period compared to that in a selected base period (a defined point in time or the average price in a certain year), multiplied by 100. Raw materials, products and energy prices, labor and construction costs change at different rates, and plant construction cost indexes are actually a ...

  3. List of price index formulas - Wikipedia

    en.wikipedia.org/wiki/List_of_price_index_formulas

    The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12]

  4. Core recovery parameters - Wikipedia

    en.wikipedia.org/wiki/Core_recovery_parameters

    It is the borehole core recovery percentage incorporating only pieces of solid core that are longer than 100 mm in length measured along the centerline of the core. In this respect pieces of core that are not hard and sound should not be counted though they are 100 mm in length.

  5. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...

  6. Cost-weighted activity index - Wikipedia

    en.wikipedia.org/wiki/Cost-weighted_activity_index

    The cost of each category and the level of activity in the base year are determined. The level of activity is then measured in a subsequent year, and the percentage changes are weighted together by the costs in the base year to get an overall percentage change in output.

  7. Expense and cost recovery system - Wikipedia

    en.wikipedia.org/wiki/Expense_and_cost_recovery...

    An expense and cost recovery system (ECRS) is a specialized subset of "extract, transform, load" (ETL) functioning as a powerful and flexible set of applications, including programs, scripts and databases designed to improve the cash flow of businesses and organizations by automating the movement of data between cost recovery systems, electronic billing from vendors, and accounting systems.

  8. Batch normalization - Wikipedia

    en.wikipedia.org/wiki/Batch_normalization

    In a neural network, batch normalization is achieved through a normalization step that fixes the means and variances of each layer's inputs. Ideally, the normalization would be conducted over the entire training set, but to use this step jointly with stochastic optimization methods, it is impractical to use the global information.

  9. Facility condition index - Wikipedia

    en.wikipedia.org/wiki/Facility_Condition_Index

    Within the US Federal Government, the "condition index" (CI) is a general measure of the constructed asset's condition at a specific point in time. [2] Within the US Federal Government, CI is calculated using the same formula of the ratio of Repair Needs to Plant Replacement Value (PRV) but results are presented as a percentage where higher ...
