The Loading Metric is a pure measurement of Schedule efficiency and is designed to exclude the effects how well that operation may perform. Calculation: Loading = Scheduled Time / Calendar Time. Example: A given Work Center is scheduled to run 5 Days per Week, 24 Hours per Day. For a given week, the Total Calendar Time is 7 Days at 24 Hours.
Many scientists apply a logarithmic transformation to the observed and simulated data prior to calculating the NSE, and this is referred to as the LNSE. [9] This is helpful when the emphasis is on simulating low flows, as it increases the relative weight of small observations.
The Kling–Gupta efficiency (KGE) is a goodness-of-fit indicator widely used in the hydrologic sciences for comparing simulations to observations. It was created by hydrologic scientists Harald Kling and Hoshin Vijai Gupta. [ 1 ]
In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. [1] It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may ...
In statistics, efficiency is a measure of quality of an estimator, of an experimental design, [1] or of a hypothesis testing procedure. [2] Essentially, a more efficient estimator needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound.
Mean time between failures (MTBF) describes the expected time between two failures for a repairable system. For example, three identical systems starting to function properly at time 0 are working until all of them fail. The first system fails after 100 hours, the second after 120 hours and the third after 130 hours.
Data envelopment analysis (DEA) is a nonparametric method in operations research and economics for the estimation of production frontiers. [1] DEA has been applied in a large range of fields including international banking, economic sustainability, police department operations, and logistical applications [2] [3] [4] Additionally, DEA has been used to assess the performance of natural language ...
Efficiency factors are used in performance rating and remuneration calculation exercises. The efficiency factor is an extremely simple to use and readily comprehensible index, the prerequisite being exact time management for maintaining the allowed times.
