LossProduction {ImportanceIndice}

Obtaining indices associated with loss of production.

Description

Allows calculating loss of production per loss source (L.P.L.S.) and its total, maximum estimated production (M.E.P.), percentage of loss of production per loss source (Percentage_L.P.L.S.=P.L.P.L.S.) and its total, n_per_sample, and attention level (A.L.).
Equations:
*L.P.L.S. = total n of the L.S. x R.P. of the L.S. Where R.P. is R2 x (1 - P) when it is of the first degree, or R.P. = ((R2 x (1 - P))x(B2/B1) when it is of the second degree. Where, R2 = determination coefficient and P = significance of ANOVA, B1 = regression coefficient, and B2 = regression coefficient (variable2), of the simple regression equation of the L.S.
*M.E.P. = Total production (P.) + SUM L.P.L.S.1 + ....L.P.L.S.n.
*Percentage_L.P.L.S. = (L.P.L.S./M.E.P.) x 100.
* n_per_sample is n per sample
*A.L. = (n of the L.S. per sample x 0.75)/Percentage_L.P.L.S..
Where, n of the L.S. per sample = n/(number of trees/evaluation frequency/years/number of plant parts evaluated). In this case, the number of trees = 20; evaluation frequency = 12 months per year for leaves, trunks, and branches, two months for bunches of flowers per year, and three months for bunches of fruits per year; years = three; and the number of plant parts evaluated = 12 leaves, 12 bunches of flowers and/or fruits, and one trunk per tree/evaluation. And, 0.75 = 1 percent of loss fruits x 0.75 (safety margin).

Usage

LossProduction(DataLossSource,Prod,Evaluation,SegurityMargen=0.75,
MaximumToleranceOfLossFruits=1)

Arguments

DataLossSource

It is an matrix object containing data from loss sources.

Prod

Matrix with a column containing the production data.

Evaluation

Matrix containing three lines with the number of evaluations performed on each individual, the number of months evaluated and the number of evaluations performed per month. Must have a column for each source of loss.

SegurityMargen

Segurity margen (default=0.75)

MaximumToleranceOfLossFruits

Maximum tolerance in percentage (default=1)

Value

The function returns several indices associated with the production loss.
