Unit 10: Simulation of a PERT Network (II)

demonstrating its ability to replicate actual traffic patterns. The importance of model validation Notes
underscores the need for careful planning, thoroughness and accuracy of the input data collection
program that has this purpose. Efforts should be made to ensure collected data is consistent with
expected values.

Example: In traffic analysis, it is typically common for a traffic engineer to perform a site
visit to verify traffic counts and become familiar with traffic patterns in the area. The resulting
models and forecasts will be no better than the data used for model estimation and validation.

Resource Allocation and Cost Considerations

PERT to include both random activity durations and project cost considerations. Project costs
include both planned activity costs and penalties for activities exceeding their allowed durations.
Several problem formulations are mentioned, and the determination of a minimum cost schedule
satisfying a predetermined project deadline is discussed in detail. This latter problem is
formulated as a separable programming problem which can be solved by the computer algorithm
documented in the appendices.

PERT/CPM is effectual tool for project planning. PERT stands for critical path method. Even
though these techniques were develop for defence applications they are useful for many
maintenance projects. The conventional “Bat Chart” as given below is adequate for a small
straight forward jobs having around 200 activities. But for larger maintenance projects such as
plant shut down and overhaul jobs where activities are many PERT/CPM techniques help us to
ascertain the logistics of different resources.

Caselet Intel ‘TEN’ to ride Piggyback on Akshaya Network

he ‘Akshaya’ model of e-services delivery will now provide Intel’s latest curriculum
module ‘Technology and Entrepreneurship’ (TEN) through its 2,200 customer service
Tcentres (CSCs) across Kerala.
Mr Anjan Ghosh, Regional Director - Corporate Affairs, Asia-Pacific, Intel, launched the
curriculum at a grassroots stakeholder roundtable held here on Tuesday.
Basic Concepts
The roundtable on ‘ICT as enabler for sustained socio-economic transformation in Kerala’
was jointly organised by Akshaya and Intel.
The roundtable highlighted the diverse sustainability pillars and supporting systems
leading to sustainability of the Akshaya centres.
The Technology and Entrepreneurship course introduces learners to basic concepts and
process of entrepreneurship, and demonstrates how technology can be used to advance a
business idea.
Using internet tools and office applications, learners research and formulate a business
idea, and create and present a business plan for the same.
Earlier Programme
Intel had launched an e-literacy programme in 2005 through Akshaya and the multinational
giant has empowered 86,000 students in Kerala in the age group of 8-16 yrs.
