DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Productivity
47. • Types (Computing Productivity)
• Total productivity
• Multifactor productivity
• Partial productivity
• The choice of productivity measure depends
primarily on the purpose of the measurement.
• For ex., If the purpose is to track improvements
in labor productivity, then labor becomes the
obvious input measure.

customers during the past week. The bank works 5
days/week and the business hours are 10:30 am – 02:30
pm. Compute the productivity measure of its tellers.
• Soln.:
• No. of business hours / day / teller = 4
• Total no. of business hours / day = 5 x 4 = 20
• Total no. of business hours / week = 5 x 20 = 100
• Productivity = (No. of customers served / week) / (No. of
hours tellers worked/week)
= 1497 / 100 = 14.97 or 15 customers / hour

53. • An organization can use productivity
measures to
• compare its performance with that of
competitors,
• assess the relative performance of its
individual departments,
• compare the relative benefits of various
inputs,
• plan the most effective use of resources.
Dept. of ME, JSSATE, Bengaluru 53
Why Productivity is Measured?
54. • Generally, methods, capital, quality, technology and management
affect productivity.
• A misconception is that workers are the main determinant of
productivity. Hence, organizations insist their employees to work
harder.
• The fact is that many productivity gains in the past have come
from technological improvements.
• However, technology alone won’t guarantee productivity gains; it
must be used wisely and thoughtfully.
• Current productivity pitfall results from employees’ use of
computers or smartphones for nonwork-related activities (playing
games or checking stock prices or sports scores on the Internet or
smartphones, and texting friends and relatives).
Dept. of ME, JSSATE, Bengaluru 54
Factors Affecting Productivity
Source: OM by W J Stevenson
55. • Capital/Labour Ratio: is a measure of whether enough investment
is made in plant, machinery, tools, etc. to make effective use of
labour hours.
• Scarcity of some resources: such as energy, water, materials,
skilled labours, etc.
• Work-force changes is steady shift of from blue-collar occupations
to….
• Innovation and technology: will be developed if enough
investment is made in R & D; Strong patenting rules are required.
• Regulatory effects: sometimes, impose substantial constraints
(pollution, health, safety, labour benefits, etc.).
• Bargaining power: of organized labour to command wage increase.
• Quality of work life describes the organizational culture -
motivation to employees for teamwork, commitment, loyalty, etc.

Decision Making
58
Dept. of ME, JSSATE, Bengaluru
• He who has a choice has trouble.
• Every decision ever taken is born out of choices.
59. • A process of consciously choosing an alternative among
the several available.
• Decision making is one of the most important basic
management skills for all of us. It is a cognitive ability. It
can differ from person to person.
• Decisions should neither be taken in haste nor be
procrastinated indefinitely.
• Making a decision which is timely and which is based on
careful analysis of various information is critical for an
operations manager.

Decision Making
60. Dept. of ME, JSSATE, Bengaluru 60
Decision Making Process
https://www.umassd.edu/fycm/decision-making/process/
61. • 1. Identify the decision to be made
• What is the problem on hand?
• What is the objective to be achieved?
• How will the decision impact people or the organization?
• Urgency and criticality of the decision
• 2. Gather relevant information
• What information is needed?
• The best sources of information
• How to get it?
• Involves both internal and external “work.”
• Internal: a process of self-assessment.
• External: obtained online, in books, from other people, and from
other sources.
Dept. of ME, JSSATE, Bengaluru 61
Decision Making Process
62. • 3. Identify the options
• Information collected helps identifying several possible paths of
action or alternatives.
• Imagination and additional information to construct new
alternatives may also be used.
• All possible and desirable alternatives are to be listed.
• 4. Weigh or Evaluate the evidence of each alternative
• Evaluate whether the need identified in Step 1 would be met or
resolved through the use of each alternative.
• Certain options seem favorable, have a higher potential for
reaching the goal.
• Place the alternatives in a priority order, based upon your own
value system.
Dept. of ME, JSSATE, Bengaluru 62
Decision Making Process
63. • 5. Choose among alternatives
• After weighing the evidences, select the alternative that seems to
be best one for you.
• A combination of alternatives may also be chosen.
• The selected alternative may very likely be the same or similar to
the alternative that is placed at the top of the list at the end of
Step 4.
• 6. Implement the chosen alternative (Take action)
• Implement the actions associated with the alternative or option
being selected.
• 7. Analyse the results
• Evaluate whether or not the chosen option has resolved the need
identified in Step 1. If not, certain steps may be repeated.
Dept. of ME, JSSATE, Bengaluru 63
Decision Making Process
64. • Operations decisions range from simple judgments to
complex analyses (these may also involve judgments).
• Judgmental decisions are made by basic knowledge,
experience and common sense.
• Both subjective and objective data is used to arrive at a
choice.
• The decisions are characterized by
– The significance of the decision being made
– The time and cost involved (limitations)
– The degree of complexity of the decision being made
Dept. of ME, JSSATE, Bengaluru 64
Characteristics of Operations Decisions
65. • Significant (or long-lasting) decisions deserve more
consideration than trivial or routine one. Ex., medical
products, investment in new plant, etc.
• Time availability and cost analysis
• Decision complexity increases when a) many variables
are involved, b) the variables are highly interdependent
or sequentially related, and c) the data describing the
variables are incomplete or uncertain.
• Example: new factory location decisions (involve
economical, social, and environmental concerns; cost on
technology and amount of automation).

80. • FC = $6,000, VC = $2 per cake, SP = $7 per cake
• a.
• b. For Q = 1,000, P = Q ( SP − VC ) − FC
• = 1,000 ($7 − $2)− $6,000 = − $1,000
• c. Profit, P = $4,000; Solve for Q using Q = (P+FC)/(SP-VC)
• d. P = $5000, Q = 2000 cakes; We know, P = Q (SP -v) – FC
• $5,00 0 = 2,000 (SP − $2) − $6, 000
• Therefore, SP = $7.50

81. Risk & Uncertainty:
• When probabilities can be assigned to the occurrence of
states of nature (events that may occur in future), the
situation is referred to as decision making under risk.
• When probabilities cannot be assigned to the
occurrence of future events, the situation is called
decision making under uncertainty.
• Decision Criteria used:
– Maximax
– Maximin
– Minimax regret
– Hurwicz
– Equal likelihood (LaPlace)

82. • A Textile MNC is contemplating the future of one of its
plants located in Mumbai. Three alternative decisions are
being considered: (1) Expand the plant and produce
lightweight, durable materials for possible sale to the
military, a market with little foreign competition; (2)
maintain the status quo at the plant, continuing
production of textile goods that are subject to heavy
foreign competition; or (3) sell the plant now. If one of the
first two alternatives is chosen, the plant will still be sold
at the end of the year. The amount of profit that could be
earned by selling the plant in a year depends on market
conditions. The following payoff table is prepared by the
top management of the company:

Decision Making – Risk & Uncertainty
84. • Maximax (Optimistic) criterion
• The decision maker optimistically assumes that ‘good
competitive conditions’ will prevail in the future.
• The decision selected will result in the maximum of the
maximum payoffs.
• Hence,
• Expand: $800,000
• Status quo: $1,300,000 ← Maximum
• Sell: $320,000
• Decision: Maintain status quo

85. • Maximin (Pessimistic) criterion
• The decision maker is pessimistic and assumes that
‘minimum payoffs’ will occur in the future.
• The decision maker selects the decision that will reflect
the maximum of the minimum payoffs.
• Hence,
• Expand: $500,000 ← Maximum
• Status quo: - $150,000
• Sell: $320,000
• Decision: Expand

86. • Minimax regret criterion
• The decision maker attempts to avoid regret by selecting the
decision alternative that minimizes the maximum regret.
• First, select the maximum payoff under each state of nature; then
all other payoffs under the respective states of nature are
subtracted from these amounts.
• The maximum regret for each decision must be determined, and
the decision corresponding to the minimum of these regret values
is selected.

87. • Minimax regret criterion
• Expand: $500,000 ← Minimum
• Status quo: $650,000
• Sell: $980,000
• Decision: Expand

88. • Hurwicz criterion
• The decision maker is neither totally optimistic (maximax
criterion) nor totally pessimistic (maximin criterion).
• The decision payoffs are weighted by a coefficient of
optimism, α, a measure of the decision maker’s
optimism.
• If α =1, the decision maker is completely optimistic; if α =
0, the decision maker is completely pessimistic. (Given
this definition, (1 - α) is the coefficient of pessimism.)

89. • Hurwicz criterion
• For each decision alternative, the maximum payoff is
multiplied by α, and the minimum payoff is multiplied by
(1 - α).
• In the given example, if α equals 0.3 (i.e., the company is
slightly optimistic) and (1 - α)=0.7, the following decision
will result:
• Expand: $800,000(0.3) + 500,000(0.7) = $590,000 ← Maximum
• Status quo: $1,300,000(0.3) - 150,000(0.7) = $ 285,000
• Sell: $320,000(0.3) + $320,000(0.7) = $320,000
• Decision: Expand

90. • Equal Likelihood:
• Each state of nature is weighted equally. That is, it is assumed
that the states of nature are equally likely to occur (weight of
0.5 each since there are two).
• Multiply the weights by each payoff for each decision.
• Select the alternative with the maximum of these weighted
values.
• Expand: $800,000(0.50) + $500,000(0.50) = $650,000 ←
Maximum
• Status quo: $1,300,000(0.50) +$150,000(0.50) = $575,000
• Sell: $320,000(0.50) + $320,000(0.50) = $320,000
• Decision is Expand
