generatepdm {mfpp}

Function to generate a PDM matrix for flexible project planning problems.

Description

Function to generate a PDM matrix for flexible project planning problems.

Usage

generatepdm(N,ff,cf,mTD,mCD,mRD,w,nR,nW,scale=1.4,QD=FALSE,lst=FALSE)

Arguments

N

Number of tasks (a numeric value)

ff

flexibility factor between [0,1] (a numeric value).

cf

connectivity factor (a numeric integer).

mTD

max value of TD (a numeric positive integer).

mCD

max value of CD (a numeric positive integer).

mRD

max value of RD (a numeric positive integer).

w

number of modes (a numeric integer).

nR

number of resources (a numeric integer).

nW

number of possible extra tasks (a positive numeric integer).

scale

scale parameter, the default value is 1.4 (a numeric value).

QD

logic parameter, the default value is FALSE, which means, the quality domain is neglected.

lst

(logic parameter, the default value is FALSE, which means, the output is a PDM matrix, while TRUE means the output is a PDM list including number of modes (w) and the number of resources (Rs).

Value

PDM

[PEM,TD, CD, QD,RD] is a Project Domain Matrix (a numeric matrix), where;

PEM

An N by N upper triangular matrix of logic domain (a numeric matrix).

TD

N by w matrix of task durations (a numeric matrix).

CD

N by w matrix of cost demands (a numeric matrix).

QD

N by w matrix of quality parameters (a numeric matrix).

RD

N by w*nR matrix of resource demands (a numeric matrix).

w

Number of completion modes (scalar, if the output is PDM list (lst=TRUE)).

Rs

Number of resources (scalar, if the output is PDM list (lst=TRUE)).
