Business Applications of Operations Research
In a sentence
This book demonstrates how to use mathematical Operations Research techniques and software to solve a wide range of common business problems and optimize decision-making across various management functions.
Operations Research provides a powerful bouquet of mathematical techniques to find the best solutions for the myriad decisions managers face, from daily operations to strategic planning. This book serves as a practical guide, demonstrating how to apply tools like linear and integer programming to solve real-world problems in operations, supply chain, finance, and marketing. The unique approach of this book is its focus on application over theory; using the LINGO software, you'll learn to model and solve complex issues like product mix, facility location, scheduling, and portfolio management. With detailed do-it-yourself instructions, you'll gain an intuitive understanding of these powerful tools, empowering you to build models for your own business needs and make optimal, data-driven decisions, even without a deep background in mathematics.
The four lenses
- Science
- Statistics
- Systems
- Strategy
The model
This model outlines the process by which structuring business problems with clear objectives and constraints, and applying Operations Research techniques, leads to optimal decisions and improved overall business performance.
Problem Structuringdesign lever
The process of formally defining a business problem by identifying key decision variables, formulating a clear objective function to be maximized or minimized, and specifying all relevant constraints and limitations.
Resource Constraintscontextual condition
The documented limitations on available resources, such as budget, time, production capacity, labor, and materials, that define the feasible solution space for a business problem.
Business Objectivescontextual condition
The clearly defined goals of the decision-making process, such as the maximization of profit or revenue, or the minimization of cost, risk, or distance.
Application of Operations Research Modelbehavioral pattern
The use of a mathematical technique (e.g., linear programming, integer programming) and solver software to analyze a structured problem and compute the optimal values for its decision variables.
Decision Optimalityoutcome metric
The degree to which a chosen course of action represents the best possible solution according to the model's objective function, given the specified constraints. This is the direct output of solving an OR model.
Business Performanceoutcome metric
The ultimate organizational outcomes resulting from the implementation of a decision, measured by key performance indicators such as profitability, cost savings, market share, or operational efficiency.

The story
The reader A manager, business professional, or student who is responsible for making complex decisions regarding operations, finance, or supply chains. They want to improve efficiency, increase profits, and make the best possible choices, but are often faced with too many variables and constraints to rely on intuition alone.
External problem
Facing complex business problems—such as determining the optimal product mix, locating facilities, scheduling production, routing vehicles, or allocating budgets—where finding the best solution is critical but difficult due to numerous options and constraints.
Internal problem
Feeling uncertain or intimidated by the complexity of quantitative analysis, and frustrated by making suboptimal decisions based on guesswork or overly simplistic spreadsheets. They worry they are leaving money on the table or are not as efficient as they could be.
Philosophical problem
It's just plain wrong to make critical business decisions with significant financial implications based on gut feel when a scientific, proven method exists to find the optimal solution and maximize value from scarce resources.
The plan
- Learn the fundamental concepts of Operations Research tools like Linear and Integer Programming.
- Follow step-by-step examples showing how to model diverse business problems from operations, supply chain, marketing, and finance.
