Definition of a System
A system is a collection of interrelated components that work together to achieve a
specific goal. It consists of various elements that interact with each other within defined
boundaries to process inputs and produce outputs.
Key Features of a System:
   1. Interrelated Components: Each part of the system is connected and affects the
      others.
   2. Defined Boundary: Every system has limits that separate it from its external
      environment.
   3. Input-Process-Output Model:
          o   Input – Data or resources fed into the system.
          o   Process – The transformation of inputs into useful outputs.
          o   Output – The result or outcome generated by the system.
   4. Feedback Mechanism: Many systems use feedback to adjust their operations
      and improve efficiency.
   5. Hierarchy of Systems: A system may consist of smaller subsystems that work
      together within a larger system.
Examples of Systems:
   •   Biological System: The human body consists of interconnected organs
       (subsystems) working together to sustain life.
   •   Computer System: A combination of hardware and software that processes
       data to produce meaningful information.
   •   Transportation System: Roads, vehicles, traffic signals, and regulations that
       enable movement.
Concept of a System
A system can be real (physical) or conceptual (abstract). It is structured in a way that
allows efficient functioning towards an objective.
Components of a System:
   1. Entities (Elements) – The individual units that make up the system.
   2. Attributes – Characteristics or properties of each entity.
   3. Relationships – The interactions between different components of the system.
   4. Environment – External factors that affect the system's operation.
Types of Systems Based on Behavior:
   •   Static System – Does not change over time (e.g., a mathematical equation).
   •   Dynamic System – Changes over time due to interactions with the environment
       (e.g., an economy)
       Abstract and Physical Systems
       Systems can be classified into Abstract Systems and Physical Systems based
       on their nature and existence.
       1. Abstract System
       An abstract system is a conceptual or theoretical system that does not have a
       physical form. It exists in the form of ideas, models, theories, or frameworks
       that help in understanding and analyzing real-world phenomena.
       Characteristics of Abstract Systems:
   •   Conceptual in Nature – Exists as an idea rather than a tangible entity.
   •   Used for Analysis and Decision-Making – Helps in planning, designing, and
       understanding complex processes.
   •   Represents Real-World Systems – Used as a blueprint or model for actual
       systems.
       Examples of Abstract Systems:
   1. Mathematical Models – Equations and formulas used to represent real-world
      scenarios. Example: E=mc2E = mc^2E=mc2.
   2. Organizational Hierarchy – A structure that defines the levels of management in
      a company.
   3. Flowcharts and Diagrams – Representing processes and workflows in business
      or computing.
   4. Economic Models – Theories that explain market behavior, such as supply and
      demand models.
    2. Physical System
    A physical system is a tangible system that exists in the real world and consists
    of actual components that interact with each other. It follows natural or artificial
    processes and operates in a defined environment.
    Characteristics of Physical Systems:
•   Has a Physical Existence – Can be seen, touched, or measured.
•   Processes Real Inputs and Outputs – Works with physical materials or energy.
•   Follows Natural or Designed Rules – Operates based on natural laws or human
    design.
    Examples of Physical Systems:
1. Human Body – A biological system made up of organs and tissues that work
   together.
2. Computer System – Includes hardware (CPU, RAM, storage) and software to
   process information.
3. Solar System – A natural system consisting of the sun, planets, and celestial
   bodies.

Deterministic and Probabilistic Systems
Systems can be classified into Deterministic Systems and Probabilistic Systems
based on the predictability of their behavior.
1. Deterministic System
A deterministic system is one in which the output is completely predictable based
on the given input. The system operates under a fixed set of rules and does not involve
any randomness or uncertainty.
Characteristics of Deterministic Systems:
   •   Predictable Behavior – The system always produces the same output for a given
       input.
   •   No Randomness – All events and processes follow a pre-defined pattern.
   •   Can Be Mathematically Modeled – Described by exact mathematical
       equations.
   •   Controlled and Repeatable – If the same conditions are applied, the same
       result will always be obtained.
Examples of Deterministic Systems:
   1. Mathematical Equations – Newton’s second law of motion:
      F=maF = maF=ma
      If force (FFF) and mass (mmm) are known, acceleration (aaa) is always
      predictable.
   2. Traffic Light System – Changes signals at fixed time intervals without
      randomness.
   3. Bank Transaction System – If a customer withdraws $100 from an account with
      $500, the balance will always be $400.
   4. Chemical Reactions – If 2 moles of hydrogen react with 1 mole of oxygen under
      fixed conditions, water is always produced.
2. Probabilistic System
A probabilistic system is one in which the outcome cannot be determined with
certainty and involves randomness or uncertainty. The system’s behavior depends on
probabilities, and different outputs may occur even with the same input.
Characteristics of Probabilistic Systems:
   •   Involves Randomness and Uncertainty – The same input may result in different
       outputs.
   •   Modeled Using Probability Distributions – Predictions are made using
       statistical methods.
   •   Difficult to Predict with Precision – Only likely outcomes can be estimated.
   •   Common in Real-Life Scenarios – Most real-world systems are influenced by
       uncertain factors.
Examples of Probabilistic Systems:
   1. Stock Market Predictions – Share prices change due to multiple unpredictable
      factors like investor behavior and economic conditions.
   2. Weather Forecasting – Meteorologists use probability models to predict rain,
      but it is not always accurate.
   3. Traffic Flow System – Traffic conditions vary depending on accidents,
      roadblocks, and driver behavior.
   4. Medical Diagnosis – A doctor can predict the probability of a disease based on
      symptoms, but the outcome is not always 100% certain.

Open and Closed Systems
Systems can be categorized as Open Systems or Closed Systems based on their
interaction with the external environment.
1. Open System
An open system is a system that interacts with its environment by exchanging matter,
energy, or information. These systems are dynamic and constantly influenced by
external factors.
Characteristics of Open Systems:
   •   Exchange of Energy and Matter – Inputs from the environment are processed to
       produce outputs.
   •   Interacts with the Surroundings – Influenced by external factors such as
       temperature, social interactions, or economic conditions.
   •   Dynamic and Adaptive – Can change over time based on feedback from the
       environment.
   •   Self-Regulating – Uses feedback mechanisms to maintain stability or improve
       efficiency.
Examples of Open Systems:
   1. Human Body – Exchanges energy (food and oxygen intake, heat loss) and matter
      (waste excretion) with the environment.
   2. Business Organization – Receives raw materials, labor, and capital from
      external sources and provides products and services.
   3. Ecosystem – Plants take in sunlight and carbon dioxide and release oxygen,
      interacting with the environment.
   4. Computer Network – A network connected to the internet constantly exchanges
      data with other systems.
2. Closed System
A closed system is a system that does not exchange matter with its external
environment, though it may still exchange energy. Such systems operate in isolation to
maintain internal stability.
Characteristics of Closed Systems:
   •   Limited Interaction with the Environment – No material enters or leaves; only
       energy exchange may occur.
   •   Self-Contained – Operates independently of external influences.
   •   More Predictable Behavior – Since it is isolated, external disruptions have little
       to no effect.
   •   Difficult to Maintain – Most systems in nature tend to interact with their
       surroundings, making true closed systems rare.
Examples of Closed Systems:
   1. Thermos Flask – Keeps liquids hot or cold by minimizing heat exchange with the
      environment.
   2. Greenhouse – Maintains internal temperature and humidity with limited
      exchange with the outside air.
   3. Mechanical Clock – Once wound, it operates without any external input until the
      energy is depleted.
   4. Chemical Reactions in a Sealed Container – No exchange of matter with the
      surroundings, though energy may be transferred.

Real-World Application of Open and Closed Systems:
   •   Engineering: A car engine is an open system because it takes in fuel and air and
       releases exhaust gases. A battery in a sealed circuit can be considered a
       closed system.
   •   Business Management: Companies operate as open systems because they
       rely on employees, suppliers, and customers.
   •   Environmental Science: The Earth's atmosphere is an open system because it
       receives solar energy and exchanges gases with space.

Decision Support System (DSS) - Definition, Characteristics, and Types of
Decisions
A Decision Support System (DSS) is a computer-based system that helps managers
and business professionals make semi-structured or unstructured decisions by
analyzing data and providing insights. DSS enhances decision-making by integrating
data, models, and analytical tools to evaluate different alternatives.
1. Definition of DSS
A Decision Support System (DSS) is an interactive system that provides relevant
information, tools, and models to assist decision-makers in analyzing data and making
informed choices. Unlike routine transaction systems, DSS is designed for complex
decision-making scenarios where there is uncertainty or multiple possible outcomes.
Example of DSS in Action:
A bank's DSS can help managers decide on loan approvals by analyzing customer
credit history, risk levels, and market trends.
2. Characteristics of DSS
   1. Supports Semi-Structured and Unstructured Decisions
          o   Unlike simple operational decisions, DSS helps in decisions that require
              human judgment and analytical models.
          o   Example: A supply chain DSS helps managers decide how much
              inventory to stock based on demand forecasts.
   2. Interactive and User-Friendly
          o   DSS provides an interface where users can enter data, apply models,
              and receive reports.
          o   Example: A financial DSS allows users to input investment data and
              generate risk reports.
   3. Data-Driven and Model-Based

          o   Example: A medical DSS helps doctors assess different treatment
              options for a patient.
3. Types of Decisions in DSS
DSS is used for three main types of decisions:
1. Structured Decisions (Routine & Repetitive)
   •   Fully defined problems where the solution follows a set of rules.
   •   Example: Payroll processing – The system calculates employee salaries based
       on fixed formulas.
2. Semi-Structured Decisions (Partially Defined)
   •   Some decision criteria are known, but human judgment is required.
   •   Example: Marketing budget allocation – DSS provides sales data, but managers
       decide how to allocate funds.
3. Unstructured Decisions (Complex & Unpredictable)
   •   Unique, one-time decisions requiring intuition and expertise.
   •   Example: Mergers and Acquisitions – DSS can analyze financial data, but
       executives must decide based on multiple factors.
4. Simon’s Model of Decision-Making
Herbert Simon proposed a three-phase model for decision-making in DSS:
   1. Intelligence Phase:
          o   Identifying the problem and gathering relevant data.
          o   Example: A company notices a decline in customer retention.
   2. Design Phase:
          o   Developing alternative solutions and analyzing their feasibility.
          o   Example: Considering loyalty programs, discounts, or personalized
              marketing campaigns.
   3. Choice Phase:
          o   Selecting the best alternative and implementing it.
          o   Example: The company decides to introduce a customer rewards
              program.
5. Classification of DSS
DSS can be classified based on their functionality and usage:
1. Data-Driven DSS
   •   Focuses on large databases and real-time data analysis.
   •    Example: Sales Forecasting DSS uses past sales data to predict future trends.
2. Model-Driven DSS
   •    Uses mathematical and simulation models to evaluate decisions.
   •    Example: Financial DSS analyzes investment risks using predictive models.
3. Knowledge-Driven DSS
   •    Uses Artificial Intelligence (AI) and Machine Learning (ML) for expert decision-
        making.
   •    Example: Medical DSS suggests treatments based on AI-driven diagnosis.
4. Communication-Driven DSS
   •    Focuses on team collaboration and shared decision-making.
