ABCanalysis {ABCanalysis} R Documentation

## Computed ABC analysis: calculates a division of the data in 3 classes A, B and C

### Description

divide the Data in 3 classes A, B and C such that

A=Data[Aind] : with low effort much yield

B=Data[Bind] : yield and effort are about equal

C=Data[Cind] : with much effort low yield

### Usage

ABCanalysis(Data,ABCcurvedata,PlotIt=FALSE)


### Arguments

 Data vector(1:n) describes an array of data: n cases in rows of one variable, if matrix or dataframe then first column will be used. ABCcurvedata only for internal usage, list from ABCcurve PlotIt default(FALSE), if variable is used, a plot is made, set with arbitrary value

### Details

Pareto point: Minimum distance to (0,1) = minimal unrealized potential

BreakEven Point: B_x is the x value of the point, where the slope of ABCcurve equals one.

For further description to p in variable AlimitIndInInterpolation see ABCcurve

### Value

Output is of type list which parts are described in the following

 Aind vector [1:j], A==Data(Aind) : with little effort much Yield Bind vector [1:l], B==Data(Bind) : effort and Yield are balanced Cind (vector [1:m], C==Data(Cind) : much effort for little Yield ABexchanged Boolean, TRUE if Point A is the Break Even and point B is the Pareto Point, FALSE otherwise A c(Ax,Ay), Pareto point or BreakEven Point indicated by ABexchanged B c(Bx,By), Pareto point or BreakEven Point indicated by ABexchanged C Submarginal point: minimum distance to [B_x,1] smallestAData Boundary AB, defined by point A or B with ABexchanged smallestBData Boundary BC, defined by point C AlimitIndInInterpolation index of AB Boundary in [p, ABC], the interpolation of the ABC plot BlimitIndInInterpolation index of BC Boundary in [p, ABC], the interpolation of the ABC plot
