ABCanalysis (version 1.1.0)

ABCanalysis: 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,PlotIt,ABCcurvedata)

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.

PlotIt

if variable is used, a plot is made, set with arbitrary value

ABCcurvedata

only for internal usage, list from 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

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
