learning curve function is defined as follows:
Y = aXb
where:
Y = the cumulative average time (or cost) per unit.
X = the cumulative number of units produced.
a = time (or cost) required to produce the first unit.
b = slope of the function when plotted on log-log paper.
= log of the learning rate/log of2.
Y = axb
Where Y = cumulative average time per unit to produce x unitsa = the time taken for the first unit of outputx = the cumulative number of units producedb = the index of learning (log LR/log2)LR = the learning rate as a decimal
=SUMPRODUCT($A$1:A1,SUBTOTAL(9,OFFSET($A$2,,COLUMNS($A$2:A2)-(COLUMN($A$2:A2)-COLUMN($A$2)+1),,1)))
Y = cumulative average time per unit or batch.
a = time taken to produce initial quantity.
X = the cumulative units of production or, if in batches, the cumulative number of batches.
b = the learning index or coefficient
Demonstrated the role of the learning curve dramatically at work when the accountant
Costs required time standard macro to work for a direct needed for the production of a number of units, where it is noted that at the time
The first Istg parchment production of these units for so certain the second time we note that it takes less time than the first time
In the third YK Wen time less than a second, and so on, and the reason is due to t he repeated whenever the production process, there is a chance
Because generate the expertise acquired its improvement in performance and this refers to the decline in the time required for the production of low cost and then
. [17]. It could be argued that the use of learning curves in the performance of activities or products lead to significant savings
In the time required to complete the work, as it is known in the world of business in general is expensive and time-savings
Time means savings in cost and increase in profits. Thus, the importance of the study of the learning curve and requires taken into

A system of incentives at the facility.
And must choose which fits with the curved nature of the work and workers and be done through the use of four types mentioned
Previously any learning curves negative, positive, and the curve of individual and collective, and at various intervals and then choose a curved
The best and that fits with the working conditions.
Learning curves are initially concerned with the relationship between cumulative quantities and cumulative average times (total cumulative time divided by cumulative quantity).
A learning curve is geometric with the general form
Y = aXb.
Y = cumulative average time per unit or batch.
a = time taken to produce initial quantity.
X = the cumulative units of production or, if in batches, the cumulative number of batches.
b = the learning index or coefficient, which is calculated as:
log learning curve percentage ÷ log2. So b for an
80 per cent curve would be log0.8 ÷ log2 = –0.322.
The normal shape of the curve is consistent manner bell, which embodies the first half of a similar picture for the second half. But statistically, it produces a theoretical mathematical expression of organizing data related to particular a large number of independent factors that were selected randomly occurred accidentally.
And regular curves come in different forms depending on the dispersion of data or standard deviations, or the type of area covered by the statistical. In any case, whatever the values of central tendency: the arithmetic mean and median number and often one with each of them. Look like regular models of curves as follows:
Because the theory is a phrase or sentence logically derived from a set of assumptions that proven public to interpret and understand things realistically relate. In spite of the evidence of the validity of the curve is relatively normal reality, this power remained limited non-exhaustive, there are plenty of cases in education and other human sciences that are not understood or interpreted canned sinusoidal normal.
As difficult to consider the normal curve theory, also be considered legally difficult, because the law itself is the theory proved correct / suitability Basically, this mutant version of a more systematic and comprehensive is the law. There exceeded last respect to the normal curve in some Arabic references is named Curve equinoctial. The reason for this is because the label to the form it takes the curve itself, without the data embodied in (or, in fact, without the data as determined by where it seems).
The format, which we call the normal curve is as we have said, the representation of statistical data pertaining to independent factors have occurred by chance or habit, navy without any external controller. The data that results from the normal factors occurred, are likely to be unusual in nature: multiple and varied by the diversity and multiplicity of factors, it represents. Thus, when you take this data organized into categories of high - minimum, a chart known as a regular in education and Calendar sinusoidal normal. It is here we see a lack of validity of the term (curve equinoctial) a statistical concept that specializes in education and psychology
Predictable improvements following the early part of the life of a production contract, when costly mistakes are made.
