PLANNING
AND DECISION AIDS-II
1.
TECHNIQUES
FOR ALLOCATING
RESOURCES.
Resources
are
the assets of the organization and include financial,
physical, human, intangible,
and
structural.
1.1
Budgeting
A
budget
is a
numerical plan for allocating
resources to specific activities.
Budgets are popular
because
they're applicable to a wide variety of organizations
and units within an organization.
1.
There
are four different types of
budgets.
a.
A
revenue
budget is a budget
that projects future
sales.
b.
An
expense
budget is a budget
that lists the primary activities undertaken by a
unit and allocates a
dollar
amount to each.
c.
A
profit
budget is a budget
used by separate units of an organization
that combines revenue
and
expense
budgets to determine the unit's
profit contribution.
d.
A
cash
budget is a budget
that forecasts how much
cash an organization will have on hand
and
how
much it will need to meet
expenses.
2.
These
budgets are based on the
assumption of a single specified
volume--fixed
budgets.
However,
volume can't be predicted exactly.
Therefore, a variable
budget is a budget
that takes into
account
the costs that vary with
volume.
1.2
Scheduling
Scheduling
involves a
list of necessary activities,
their order of completion,
which is to do each,
and
time needed to complete them.
Some useful scheduling tools include the
following.
1.2.1.
The Gantt
chart,
named after Henry Gantt, is a
scheduling chart that visually
shows actual and
planned
output over a period of
time.
A
Gantt
chart is a
specialized bar chart that
shows the current progress on each major
project activity
relative
to necessary completion
dates.
1.
A
project is broken down into
separate main activities listed on the
left side of the
chart.
2.
The
time frame is listed at the top or the
bottom of the chart.
3.
The
duration and scheduling of activities is
shown by a bar.
4.
Gantt
charts do not show interrelationships
among activities.
5.
Software
packages for creating and
using Gantt charts (and
many other decision
tools)
on computer are becoming widely
available.
1.2.2
PERT,
or Program Evaluation and Review
Technique
PERT
is a network planning method
for managing and controlling
large one-time projects. It is a
technique
for scheduling complicated
projects comprising many activities,
some of which are
interdependent.
A
PERT
network is a
flowchart like diagram that
depicts the sequence of activities needed
to complete a
project
and the time or costs associated
with each activity.
1.
All
of the major activities in the project
are specified.
2.
The
sequences of these activities are
determined
3.
A
network
diagram a
graphic depiction of the interrelationships
among activities,
is
constructed.
a.
An
activity
is a
work component to be accomplished, and is
represented
by
an arrow on the network diagram.
b.
An
event
(or node) represents
a single point in time that is the
beginning
or
the ending of an activity.
4.
Three
time estimates for each
activity are determined and an
expected time is
calculated
for each activity.

5.
The
critical
path is the path of
activities and events in the network
that will take
the
longest time to complete
a.
Delays
on any activities on the critical path
mean that the project will
be
delayed.
b.
Slack
is the
degree of latitude about when
various activities can be
started
without
endangering the completion date of the
entire project.
6.
After
the project has begun,
actual times for completion
of each activity are
collected
and recorded on the PERT
network so that any
rescheduling and
adjustments
can be made as quickly as
possible.
Please
remember in PERT charts the
followings:
1)
Events
are
end points that represent
the completion of major activities in a PERT
network.
2)
Activities,
which
are the time or resources required to
progress from one event to another in
a
PERT
network.
3)
Slack
time is the amount of
time an individual activity can be
delayed without delaying the
whole
project.
4)
Critical
path is the
longest or most time-consuming
sequence of events or activities in a
PERT
network.
1.3
Breakeven
Analysis
Breakeven
analysis is a
technique for identifying the
point at which total revenue
is just sufficient
to
cover total costs.
1.4
Linear
Programming
Linear
programming is a
mathematical technique that
can be used to solve
resource allocation
problems.
Linear
programming (LP) is a
quantitative tool for
planning how to allocate
limited or scarce
resources
so that a single criterion or
goal (often profits) is
optimized.
1.
It
is the most widely used quantitative
planning tools in
business.
2.
There
are optimal conditions for
using linear programming.
a.
A
single objective must be
achieved.
b.
Attainable
constraints exist.
c.
Variables
are linearly related to the objective,
i.e., and increase
(or
decrease)
in the variable leads to a proportional
increase (or decrease)
in
the
objective.
2.
CONTEMPORARY
PLANNING TECHNIQUES.
Two
planning techniques that are
appropriate for planning in an
environment that's both
dynamic and
complex
are project management and
scenario planning.
2.1
Project
Management
A
project
is a
one-time-only set of activities that
has a definite beginning and ending
point in time.
Project
management is the
task of getting a project's activities done on time,
within budget, and
according
to
specifications.
Project
Management Process.
There
are seven steps in the
project planning
process.
a.
Define
objectives.
b.
Identify
activities and resources.
c.
Establish
sequences.
d.
Estimate
time for activities.
e.
Determine
project completion
date.
f.
Compare
with objectives.
g.
Determine
additional human resource
requirements.

The
role of the project
manager
a.
The
only real influence project
managers have is their communication
skills and their power
of
persuasion.
b.
Team
members seldom work on just
one project; they're usually assigned to
two or three at any
given
time.
2.2
Scenario
planning
A
scenario
is a
consistent view of what the future is
likely to be.
1.
Developing
scenarios also can be
described as contingency planning.
2.
The
intent of scenario planning is
not to try to predict the future
but to reduce uncertainty by
playing
out potential situations under
different specified conditions.
3.
Scenario
planning is difficult to use when
forecasting random events
3.
Other
Planning Techniques:
3.1
Queuing
or waiting-line models are
mathematical models that
describe the operating
characteristics
of queuing situations.
1.
Queuing
situations can be any
combination of single-server or
multiple-server
queues.
a.
Single-server
queues involved service
provided at a single
point.
b.
Multiple-server
queues occur when a number of
stations draw from a
single
line.
2.
Queuing
models allow managers to vary the
parameters of a situation to
determine
the
probable effects.
3.2
Simulation
Models
Simulation
is a mathematical imitation of reality.
It is used when the situation is too
complex for
linear
programming or queuing theory.
3.3
Decision
Trees
Trees
are graphic models displaying
structures of a sequence of alternative
course of action and
usually
showing payoffs associated with various
paths and probabilities
associated with
potential
future
conditions.
