  2. Efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Efficiency_ratio

    The efficiency ratio indicates the expenses as a percentage of revenue (expenses / revenue), with a few variations – it is essentially how much a corporation or individual spends to make a dollar; entities are supposed to attempt minimizing efficiency ratios (reducing expenses and increasing earnings). The concept typically applies to banks.

  3. Efficiency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Efficiency_(statistics)

    The relative efficiency of two procedures is the ratio of their efficiencies, although often this concept is used where the comparison is made between a given procedure and a notional "best possible" procedure.

  4. Days in inventory - Wikipedia

    en.wikipedia.org/wiki/Days_in_inventory

    Days in inventory (also known as "Inventory Days of Supply", "Days Inventory Outstanding" or the "Inventory Period" [1]) is an efficiency ratio which measures the average number of days a company holds its inventory before selling it. The ratio measures the number of days funds are tied up in inventory.

  5. Efficiency - Wikipedia

    en.wikipedia.org/wiki/Efficiency

    Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.

    [5] [6] As the metric is averaged over the length of a player's entire career a decrease in efficiency later in his career means a player can move down in the ranking; Jordan's PER took a big hit in the final two years of his career when he returned to the game with the Washington Wizards, posting 20.7 in his penultimate season and 19.3 in his ...

  7. Seasonal energy efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Seasonal_energy_efficiency...

    The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity.

    Additionally, cost management was evident with an operating ratio improvement to 58.7% from 60.9% a year ago. ... Freight car velocity and fuel efficiency also saw marginal gains, enhancing Union ...

  9. Coefficient of performance - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_performance

    A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new methodology which gives a better indication of expected real-life performance of heat pump ...
