Business forecasting

The output from the mathematical model

Management activities are intricate and require a scientific approach to study and forecast outcomes. This is where management science comes in, which is closely linked to two essential disciplines, operations research, and industrial engineering. The credit for the development of modern scientific management techniques goes to Frederick Taylor, known as the father of management science, who spearheaded the development of systematic management techniques in Philadelphia in the 1880s.

Taylor defined management science as an approach that integrates scientific research methods to address business problems. Additionally, there are different levels at which management science research can be carried out.

At the fundamental level of mathematical disciplines, there exist three levels: optimization, probability, and theory of dynamical systems. On the other hand, the modeling level deals with the analysis of business models, mathematical analysis, data collection and analysis, computer implementation, experimentation, and problem-solving. This level falls under management science, with economics and statistics playing a crucial role as primary drivers.

The application level of economics for engineering disciplines is the third and final level. Its aim is to create tangible results that make a difference in the real world. It endeavors to initiate change and act as a catalyst for progress.

Characteristics of management science

Primarily there are five characteristics of management science. These five characteristics are as follows:

1. Functional relationships examination from an overview of systems

It is imperative to recognize that the actions of one department can have significant repercussions on the operations of other departments within an organization. Therefore, it is crucial to identify all crucial interactions and assess their impact on the organization as a whole.

During the early stages, management science projects intentionally establish a functional relationship that fosters significant interaction between their individual components and related elements, ensuring they are all integrated into a unified problem statement. The system overview examines the entire area under the manager's control, providing a foundation for investigating performance issues at various levels.

2. Interdisciplinary approach

Management science operates on the basic principle of analyzing a problem from various perspectives and tackling it from multiple angles. This approach enables it to effectively resolve complex issues that may have otherwise been difficult to solve.

A chemical scientist, engineer, or mathematician may approach problem-solving with different theories, manufacturing processes, or mathematical relationships. Similarly, a chartered accountant may analyze the relationship between inventory management, cost components, and the organization's balance sheet by considering various cost factors, including overheads, expenses, and direct labor costs.

The interdisciplinary nature of management is essential because a problem can have various individual aspects that require expertise from different fields such as biology, accounting, economics, mathematics, engineering, statistics, psychology, and more.

3. Understand and uncover different problems for studies:

In management science, the third trait highlights the likelihood of encountering new problems while attempting to solve existing ones due to the involvement of multiple disciplines. Given that numerous problems are interconnected, it is imperative to approach each issue from various angles and first acknowledge its existence. However, it is crucial to recognize that not all interrelated problems can be remedied using the same approach, and diverse solutions must be employed.

This is to ensure that maximum benefits are obtained.

4. Using the modeling process approach for solving problems

Management science employs a methodical approach to problem-solving, utilizing a modeling process that relies on mathematical models to find solutions.

5. Application of science to decision making

Incorporating scientific principles into the decision-making process is a key aspect of management science. Businesses face a plethora of complex decisions each day, which are influenced by various departments and situations. Due to this complexity, management science is often utilized to tackle these problems effectively. As the outcomes of these decisions can impact the organization at multiple levels, it is crucial to apply this process with utmost care and diligence.

This is the reason why the use of management science is very crucial in decision making.

Management science tools

The following are a few of the tools which are designed specifically to solve the problems of management with the help of management science.

1. Decision matrices

A decision matrix is a useful tool in problem-solving situations that involve investment and allocation. It allows for a tabular representation of potential solutions, which can aid in identifying a limited number of viable options.

2. Decision tree

A decision tree is a mathematical model that is used to solve decision-making problems and is represented with the help of a tree.

3. Network models

Project management tools are essential for managing complex projects and planning. Commonly used network models include CPM and PERT. CPM focuses on controlling costs and time, while PERT is used in research and development projects.

4. Mathematical programming

Mathematical programming involves optimizing the achievement of a specific goal within predetermined constraints and requirements. Its applications are diverse, spanning across military engineering, business economics, and public service sectors.

Mathematical programming is used primarily as an aid to the allocation problems’ solution.

5. Branch and bound

6. Dynamic programming:

When faced with a multitude of problems, or even just one particularly complex problem, there is a step-by-step method that can be used to find a solution. This method is specifically designed to tackle managerial-level problems and can be applied when alternative solutions exist for the problem at hand.

Dynamic programming is focused on examining sequential decisions, making it a powerful tool for decision making. This approach is typically sequential, but can be adjusted to fit that format if it is not already.

7. Game theory

Game theory is a field of mathematics that analyzes strategic interactions in competitive situations where the outcome of an individual's decisions depends on the actions of others. It has applications in diverse areas such as business, warfare, and biology, but is particularly relevant in management science for decision-making. John Forbes Nash Jr. is credited with founding game theory.

8. Markov chains

When the units or system change with time then Markov chains are used to predict the outcome.

9. Simulation models

Simulation models are employed to analyze intricate systems that cannot be studied effectively through other models. The primary and descriptive message type simulation model is utilized in management science when all other models prove ineffective.

10. Queuing model

This model is commonly referred to as the waiting line model and is used to analyze various problems with different queues. Special descriptive models are developed to predict the performance of these queues.
