What is Industrial Engineering?

The Industrial Engineer analyzes and specifies integrated components of people, machines, and facilities to create efficient and effective systems that produce goods and services beneficial to mankind.

Industrial Engineering is concerned with the design of production systems.

What is a Production System?

The IE focuses on "how" a product is made or "how" a service is rendered.

Anywhere there is a "value-added" enterprise, there is a production process.

The goal of Industrial Engineering is improving the "how." .

What is meant by improving?

Productivity means getting more from the resources being expended, namely being efficient.

Quality judges the value or effectiveness of the output.

Generally, the criteria for judging improvement are productivity and quality.

Integrated Approach

Integrated Approach

Why emphasize the system?

Production processes are composed of many interacting parts, all of whom work together. Experience has taught that changes to one portion may not result in improvements to the whole. Thus Industrial Engineers generally work with tools that emphasize systems analysis and design.

Industrial Engineering focuses on systems design.

Are Industrial Engineers directly concerned with manufacturing?

All IE's take at least one manufacturing course, which deals with manufacturing processes, and other courses closely associated with manufacturing.

Every IE is therefore knowledgeable about metal working machinery and processes. Further, related courses address manufacturing as a system.

The manufacturing industry has and remains a manifest concern of Industrial Engineering.

Fundamentally, Industrial Engineering has no basic physical science like mechanics, chemistry, or electricity. Also because a major component in any production system is people.

Industrial Engineering has a person portion. the human aspect is called ergonomics/human factors.

A more subtle difference between Industrial Engineering than other engineering disciplines is the concentration on discrete mathematics. IE's deal with systems that are measured discretely, rather than metrics which are continuous. The industrial engineering courses employ mathematical models as a central device for understanding their systems.

What Makes Industrial Engineering different from other engineering disciplines?

What are the basic sciences for Industrial Engineering?

System characterization thus employ Mathematical, Statistical, and Computer models and methods Industrial Engineering tools such as Optimization, Stochastic processes, and Simulation. the IE tools to understand traditional production elements as economic analysis, Production planning, Facilities design, Materials handling, Manufacturing systems and processes, Job analysis, and so forth.

Why is statistics important in Industrial Engineering?

All IE's take at least one course in probability and one course in statistics.

Industrial Engineering specialty

courses that follow these include

quality control, simulation, and

stochastic processes.

Further the traditional courses in production planning, economic risk assessment, and facilities planning employ statistical models for understanding these systems.

Some of the other engineering disciplines take some probability and statistics, but none have integrated these topics more into their study of systems.

How does computing influence Industrial Engineering?

Probably no other aspect of technology has greater potential impact on Industrial Engineering than computing. Like all other engineers, IE's take computer programming. Specific Industrial Engineering specialty courses like real-time control and simulation expanding the role of computer science principles within Industrial Engineering.

Both computer science and Industrial Engineering share a common interest in discrete mathematical structures.

What are the specialties of Industrial Engineering?

Finally Ergonomics deals with the human equation.

Industrial Engineering at the undergraduate level is generally seen as a composition of four areas.

Operations Research (OR) includes a. Optimization, b. Decision analysis, c. Stochastic processes, d. and Simulation.

Production generally includes such aspects as economic analysis, production planning and control, quality control, facilities design, and other aspects of world-class manufacturing.

Third is Manufacturing processes and systems.

Role of Industrial Engineer

Industrial engineers analyze and evaluate methods of production and point out ways to improve them. They decide how a company should allocate its limited tangible resources (equipment and labor) within the framework of existing physical constraints (physical plant).

An industrial engineer’s most difficult task is communicating his observations and suggestions to company executives, many of whom are emotionally invested in their traditional way of doing business.

Industrial engineers must be tactful in what they say and in how they say it. In addition to tact, being a successful industrial engineer requires charm and the willingness to stand by one’s recommendations even in the face of unresponsive management.
