CPM and
PERT
CPM and PERT
CPM (Critical Path Method) and PERT
(Program Evaluation and Review Technique)
are network based methods designed to assist
in the planning, scheduling, and control of
projects. A project is a collection of
interrelated activities
PERT Networks
In PERT the duration of any activity is
indeterministic. It bases the duration of an
activity on three estimates:
Optimistic Time, a
Most Likely Time, m
Pessimistic Time, b
The range [a, b] is assumed to enclose all
possible estimates of

Some problems

In this lecture we look at some
problems that uses the results
from Duality theory (as discussed
in Chapter 7).

Dual Problem of an LPP
Given a LPP (called the primal problem),
we shall associate another LPP called the dual
problem of the original (primal) problem. We
shall see that the Optimal values of the primal
and dual are the same provided both have
finite fea
MATRIX FORMULATION
OF THE LPps
In this lecture we shall look at the matrix
formulation of the LPPs. We see that the
Basic feasible solutions are got by solving
the matrix equation BX b

of the contraint matrix of the L

Lecture 6
Abstract If in a starting simplex tableau,
we dont have an identity submatrix (i.e. an
obvious starting BFS), then we introduce
artificial variables to have a starting BFS.
This is known as artificial
Algebraic Solution of LPPs - Simplex
Method
To solve an LPP algebraically, we first put it
in the standard form. This means all
decision variables are nonnegative and all
constraints (other than the nonnegativity
restrictions) are equations with nonnegati
The Simplex algorithm
Abstract: In this lecture we discuss the
computational aspects of the Simplex
algorithm. We shall see how a LPP is put
into a simplex tableau. Starting from a BFS,
we explain how to proceed step by step till
we reach the optimal solu

Goal programming
The LPP models discussed so far are based on the
optimization of a single objective function. There
are situations where multiple objectives are to be
met. We now present the goal programming
technique for solving multi objective models.

Goal Programming
Goal Programming is a fancy name for a very simple
idea: the line between objectives and constraints is
not completely solid. In particular, when there are a
number of objectives, it is normally a good idea to
treat some or all of them as

Definition of a Vector
Let p1, p2, , pn be any n real numbers and P an ordered set of these real numbers
that is,

Then P is an n-vector (or simply a vector). The ith com
