Multi Criteria Decision Analysis (MCDA) is a powerful tool that can help you make well-informed decisions by considering multiple criteria and alternatives. It combines qualitative and quantitative aspects to assess complex problems, taking into account the potential trade-offs, conflicts, and synergies between different objectives.
MCDA is formal approach for selecting the best among identified choices, considering several different factors or criteria that are often in conflict with one another.
There are various MCDA methods, such as Analytic Hierarchy Process (AHP), Weighted Sum Model (WSM), and ELECTRE. Each method has its strengths and weaknesses, but all seek to simplify complex problems and provide decision-makers with the information they need to make informed choices.
MCDA methods can be applied in a wide range of fields such as environmental management, urban planning, healthcare, business, and transportation, among others.
Carrying out a Multi Criteria Decision Analysis typically involves the following steps:
Decision Tree Analysis is a graphical technique that helps visualize and evaluate decision-making processes under uncertainty. It represents decisions as branches of a tree-like structure, with each ‘node’ representing a decision point, chance event, or an outcome.
Consider a simple example of a company deciding whether to invest in a new project or not. The decision tree will have two decision branches (invest and don't invest) and potential outcomes for each, such as profit or loss, which are further divided based on the likelihood of occurrence.
To construct a decision tree, follow these steps:
Decision Tree Analysis can be applied in various real-life contexts, such as:
Decision Matrix Analysis, also known as the Pugh Method, is a systematic approach to evaluating and comparing multiple alternatives based on specified criteria, where each criterion is assigned a weight according to its importance. This technique is particularly valuable when you need a simple yet transparent way to make trade-offs among different alternatives.
A Decision Matrix consists of rows and columns, representing alternatives and evaluation criteria, respectively. The essential components of a Decision Matrix Analysis include:
Alternatives | The options being considered in the decision-making process. |
Criteria | The factors or aspects used to assess and compare the alternatives. |
Weights | Quantitative values assigned to criteria, reflecting their relative importance. |
Scores | Values assigned to each alternative according to their performance with respect to each criterion. |
Weighted Scores | Calculated by multiplying individual scores by their respective criteria weights. |
Total Weighted Scores | The sum of weighted scores for each alternative, forming the basis for comparison. |
To conduct a Decision Matrix Analysis, follow these steps:
Differential Analysis, also known as Incremental Analysis, focuses on assessing the changes in costs, revenues, and profits resulting from different decision alternatives. This approach emphasizes the differences between alternatives rather than focusing on their total or individual values. By analysing these incremental differences, you can make more informed decisions that maximize the benefits and minimize potential drawbacks.
Consider, for example, the make or buy decision, where a company must decide whether to produce a product in-house or to outsource production. Differential Analysis can help identify and compare the additional costs associated with each alternative. Such costs may include materials, labour, rent, and other overheads.
Some key factors to consider in a thorough Differential Analysis include:
To demonstrate the usage of Differential Analysis, let's consider a simple example. Assume that a bakery wants to decide whether to invest in a new oven. The new oven would increase electricity costs, necessitate employee training, and have an acquisition cost, but it would also increase production capacity, leading to higher revenues. A Differential Analysis would help the bakery compare the incremental costs and benefits of purchasing the new oven against not making the investment.
In the real world, Differential Analysis is used in a variety of contexts to facilitate decision-making. Here are a few scenarios in which this approach can prove quite useful:
In business and personal decision-making, risks are an inevitable aspect that cannot be ignored. Proper evaluation of risks helps minimise potential negative consequences and increase the likelihood of success. Decision Risk Analysis involves the identification, analysis, and assessment of uncertainties associated with potential outcomes of a decision-making process.
Key objectives of Decision Risk Analysis include:
There are several ways to categorize risks involved in decision-making:
Several techniques can be employed to evaluate and manage the risks associated with decision-making effectively. Some popular methods include:
By employing these techniques, decision-makers can better understand and navigate the uncertainties and risks inherent in their choices, leading to more informed and robust decisions. Using a blend of these techniques can provide a comprehensive picture of risks and their potential impacts, ensuring a more holistic approach to decision-making.
Decision Analysis is a crucial part of Further Mathematics.

It enables a comprehensive understanding of the internal and external factors affecting a decision, which allows for better assessment of potential outcomes and improved strategic planning for future growth.
To perform decision tree analysis, follow these steps: 1) Draw a decision tree with branches representing choices and uncertainties, 2) Assign probabilities and values to branches, 3) Calculate the expected values for each decision, and 4) Choose the decision with the highest expected value.
Break-even analysis helps in decision making by determining the level of sales or production at which a business covers its costs, without making a profit or loss. It identifies the minimum point of financial viability and assists in evaluating the profitability of various choices, aiding in informed decision-making, and highlighting potential risks.
Decision matrix analysis is a quantitative technique used in decision-making to compare and prioritise different options by evaluating them against chosen criteria. It involves creating a decision matrix that highlights the choices, criteria, and their assigned weights. This helps to identify the most suitable option by calculating the total scores for each choice.
Decision analysis is a systematic, quantitative approach to evaluating and making complex decisions, often involving uncertainty, risk, and multiple criteria. It involves constructing decision models, analysing data, and producing recommendations to guide informed decision-making.
