Managers are constantly faced with choices that can determine the success or failure of their organisations. Whether it is allocating resources, planning projects, or managing risks, the ability to analyse decisions systematically is essential. This Series provides the foundation for understanding how structured approaches can transform complex business challenges into manageable solutions, preparing you to engage confidently with the analytical tools that will be explored throughout the course.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS The aim of this Series is to equip you with the fundamental principles and techniques of business decision analysis, enabling you to define, explain, and apply these concepts in practical situations. By the end of the Series, you will be able to recognise the elements of decision analysis, interpret operational research approaches, and appreciate the role of mathematical and simulation models in guiding managerial choices. We shall commence this Series by examining the basic elements of decision analysis, including types of decision situations and the use of decision trees. Next, we will explore the operational research approach, focusing on systems, system analysis, and modelling. Following that, we will move into the mathematical foundations of decision analysis, where transportation, assignment, and game theory models will be introduced. Afterwards, we will consider managerial applications such as inventory control, line balancing, routing, sequencing, and project management. Finally, we will wrap up by studying risk and simulation, highlighting how probability judgments and simulation techniques can be applied to business decision situations. Series Learning Outcomes Upon completing this Series, you should be able to: • 2.1 define the basic elements of decision analysis, • 2.2 explain different types of decision situations and illustrate them using decision trees, • 2.3 describe the scope of operational research and analyse the role of systems and system analysis in decision-making, • 2.4 demonstrate how to construct and interpret models within operational research, • 2.5 apply mathematical programming techniques such as transportation and assignment models to business decisions, • 2.6 analyse conflict situations using the principles of game theory, • 2.7 evaluate managerial applications of decision analysis including inventory control, line balancing, routing, sequencing, and project management, • 2.8 apply probability judgments to managerial decisions and design risk profiles for business scenarios, and • 2.9 demonstrate the use of simulation techniques to model and solve business decision problems. 1.1 Elements of Decision Analysis 1.1.1 Basic concepts of decision analysis Decision-making in business involves choosing among alternatives to achieve organisational goals. Decision analysis is a structured approach that applies logical, mathematical, and
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS statistical techniques to evaluate options and select the most appropriate course of action. It helps managers reduce uncertainty and make choices that are consistent with organisational objectives. A key feature of decision analysis is its reliance on criteria (standards used to judge alternatives) and alternatives (possible courses of action). By systematically comparing these, decision analysis provides clarity and confidence in managerial choices. Fill in the blank: Decision analysis provides managers with a structured way to reduce ______ when making choices. 1.1.2 Types of decision situations Business decisions can be classified into different situations depending on the level of certainty involved. These include:
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS • Decision under certainty: All outcomes are known and predictable. • Decision under risk: Probabilities of outcomes are known, but the exact result is uncertain. • Decision under uncertainty: Neither outcomes nor probabilities are known, making choices more complex. Managers must recognise which situation they are facing, as this determines the tools and techniques to be applied. Fill in the blank: When probabilities of outcomes are known but results remain uncertain, the situation is described as decision under ______.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS 1.1.3 Decision trees as analytical tools A decision tree is a graphical representation of possible choices and their outcomes. It uses branches to depict decisions and consequences, allowing managers to visualise complex scenarios. Decision trees are particularly useful in situations involving risk, as they can incorporate probabilities and expected values. For example, a company deciding whether to launch a new product can use a decision tree to map out possible market responses, associated costs, and expected revenues. This helps in identifying the most profitable option. Fill in the blank: A decision tree represents choices and outcomes using ______ that branch out from a starting point. Pilot questions 1.1
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS 1. Which term refers to a structured approach that applies logical and mathematical techniques to evaluate options? 2. What type of decision situation occurs when all outcomes are known and predictable? 3. Which tool uses branches to represent choices and outcomes in decision analysis? 4. In which type of decision situation are probabilities known but exact outcomes uncertain? 5. What are the two key features of decision analysis that guide managers in making choices? 1.2 Operational Research Approach to Decision Analysis 1.2.1 Definition and scope of operational research Operational research (OR) is the application of scientific methods, mathematical models, and analytical reasoning to support decision-making in complex organisational situations. It seeks to provide optimal or near-optimal solutions to problems involving limited resources, competing objectives, and uncertainty. The scope of OR extends across industries such as manufacturing, logistics, healthcare, and finance. It helps managers design efficient systems, allocate resources effectively, and evaluate alternative strategies. Fill in the blank: Operational research applies ______ methods and analytical reasoning to support decision-making in organisations.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS 1.2.2 Systems and system analysis in decision-making A system is a set of interrelated components working together to achieve a common goal. In business, systems may include production processes, supply chains, or information networks. System analysis involves studying these components, their interactions, and their impact on overall performance. System analysis helps managers identify bottlenecks, inefficiencies, and opportunities for improvement. By viewing the organisation holistically, decisions can be made that enhance overall effectiveness rather than optimising isolated parts. Fill in the blank: A system is defined as a set of ______ components working together to achieve a goal.
