percent: Function to calculate desired project completion characteristic of a project structure.

Description

Function to calculate project completion desired charcateristic type either cost, or quality and/or resources with or withoud quality parameters, or score ratio or time duration of a project scenario for the given ratio and completion modes.

Usage

percent(PDM,type=c("c","q","qd","r","s","t"),w=2,Rs=2,ratio=1)

Value

w

Number of completion modes (a numeric integer).

Rs

Number of resources (a numeric integer).

ratio

ratio of desired characteristic of a project between interval [0,1] (a numeric value).

Cc

Project completion cost (a numeric value).

Cq

Project completion quality when quality parameters are not considered (a numeric value).

Cq

Project completion quality when quality parameters are considered (a numeric value).

CR

Minimum resources for the completion when quality parameters are not considered (a numeric value).

CR

Minimum resources for the completion when quality parameters are considered (a numeric value).

Cs

Minimum completion score ratio of a project (a numeric value).

Ct

Minimum task duration to project a project (a numeric value).

Arguments

PDM

is 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).

type

Type to calculate the project completion characteristic either cost or quality with or without defined quality parameters, or resources with or without quality parameters, or minimum completion score or minimum task duration of a project scenario (a logical value).

w

Number of completion modes (a numeric integer).

Rs

Number of resources (a numeric integer).

ratio

ratio of desired characteristic of a project between interval [0,1] (a numeric value).
