phase3R Documentation

Function to simulate the effects of the change of customer claims.

Description

Phase 3 selects P percent of nodes (i.e. tasks) or arcs (i.e. dependencies), where the score value can be changed up to the maximal change effects.

Usage

phase3 (x,p=0.10, s=0.50, nW=0)

Arguments

x

is either a Project Domain Matrix (a numeric matrix), where PDM=[LD,TD, CD, <QD,RD>]. LD is an N by N upper triangular matrix of logic domain (a numeric matrix); TD is an N by w matrix of task durations (a numeric matrix); CD is an N by w matrix of cost demands (a numeric matrix); QD is an optinal N by w matrix of quality parameters (a numeric optional matrix); RD is an N by w*nR matrix of resource demands (a numeric optional matrix), or PDM list, which contain a PDM matrix, and the number of completion modes (w) and the number of resources.

p

Probability of structural change (default value is p=0.10).

s

Increase/decrease ratio of priorities (default value is s=0.50).

nW

Number of unplanned tasks (default value is nW=0).

Value

PDMout

PDM matrix with same structure as the input PDM matrix (a matrix).
