Schedule for deterministic projects

Description

This function calculates the duration of the project, the slacks for each activity, as well as the schedule of each activity.

Usage

schedule.pert(
  duration,
  prec1and2 = matrix(0),
  prec3and4 = matrix(0),
  PRINT = TRUE
)

Arguments

`duration`	Vector with the duration for each activity.
`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`.
`PRINT`	Logical indicator to show the schedule represented in a graph (Default=TRUE)

Value

A list of a project schedule and if PRINT=TRUE a plot of schedule.
