last.time: Last time for a deterministic projects

In ProjectManagement: Management of Deterministic and Stochastic Projects

Last time for a deterministic projects

Description

This function calculates the last time for one project.

Usage

last.time(prec1and2 = matrix(0), prec3and4 = matrix(0), duration, early.times)

Arguments

prec1and2	A matrix indicating the order of precedence type 1 and 2 between the activities (Default=matrix(0)). If value (i,j)=1 then activity i precedes type 1 to j, and if (i,j)=2 then activity i precedes type 2 to j. Cycles cannot exist in a project, i.e. if an activity i precedes j then j cannot precede i.
prec3and4	A matrix indicating the order of precedence type 3 and 4 between the activities (Default=matrix(0)). If value (i,j)=3 then activity i precedes type 3 to j, and if (i,j)=4 then activity i precedes type 4 to j. Cycles cannot exist in a project, i.e. if an activity i precedes j then j cannot precede i.
duration	Vector with the duración for each activity.
early.times	Vector with the early times for each activities.

Value

Last time vector.
