Science and Engineering
❖ Engineering and science have developed in a parallel, complementary fashion, although not always the same place.
❖ Whereas science is concerned with the quest for basic knowledge,
❖ Engineering is concerned with the application of scientific knowledge to the solution of problems and the quest for a “better life”.
Science and Engineering
❖ In its efforts to solve problems, engineering provides feedback to science in areas where new knowledge is needed.
❖ Thus, science and engineering work hand in hand.
Job, Occupation and Profession
Is engineering a job, or an occupation, or a profession?
❖ What is the difference?
Is engineering a job, or an occupation, or a profession?
❖ Job: a piece of work; especially: a small miscellaneous piece of work undertaken on order at a stated reset (Marriam-Webster Dictionary)
❖ Occupation: An activity that serves as one’s regular source of livelihood; a vocation.
Exp. I have a job at a restaurant and my occupation is a cook.
❖ Profession:
❖ It requires extensive formal education,
❖ special organization set and enforce various standards for members of the profession,
❖ a significant service is provided to the public,
❖ the work requires significant skill, judgment and discretion.
Designing a building would be called a profession, whereas, constructing a building is an occupation.
Engineering
Engineering
❖ The profession in which a knowledge of the mathematical and natural science gained by study, experience and proactive is applied with judgement to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind.

The Engineering Process
❖ Analysis is concern with resolving something into its basic elements so it is concerned with existing systems.
❖ Synthesis is concern with combining elements into a whole so it concerned with a new or improved system.

Beginning of Engineering
❖ We choose 1750 as the beginning of modern engineering for two reasons:
❖ Engineering schools appeared in France in the 18th century,
❖ The term civil engineering was first used in 1750.
❖ To understand the role of industrial engineering (IE) in today’s complex world, it is helpful to learn the historical developments of engineering that were involved in the progress of IE.
Historical Developments
Historical Developments
❖ Principles of early engineering were first taught in military academies and were concerned primarily with road and bridge construction and defenses.
❖ Interrelated advancements in the fields of physics and mathematics laid the groundwork for practical applications of mechanical principles.
Historical Developments (cont.)
❖ The first significant application of electrical science was the development of the telegraph by Samuel Morse (1840).
❖ Thomas Edison’s invention of the carbon lamp (1880) led to widespread use of electricity for lighting purposes.
Historical Developments (cont.)
❖ The science of chemistry is concerned with understanding the nature of matter and learning how to produce desirable changes in materials. ❖ Fuels were developed needed for the new internal
combustion engines. ❖ Lubricants were needed for mechanical devices. ❖ Protective coatings were needed for houses, metal
products, ships, and so forth.
Historical Developments (cont.)
❖ Five major engineering disciplines (civil, chemical, electrical, industrial, and mechanical) were the branches of engineering that came out prior to the 1st World War.
❖ Developments following 2nd World War led to other engineering disciplines, such as nuclear engineering, electronic engineering, aeronautical engineering, and even computer engineering.
Historical Developments (cont.)❖ As industrial organizations merges to capitalize on the
rapidly developing array of technological innovations, the size and complexity of manufacturing units increased dramatically.
❖ Mass production (production of a large number of similar products efficiently) was made possible through two important concepts:
❖ Interchangeability of parts
❖ Specialization of labor
❖ Through mass production the unit cost of consumer products was reduced dramatically.
Historical Developments (cont.)
❖ During the early part of this movement it was recognized that business and management practices that had worked well for small shops and farms simply were inadequate for large, complex manufacturing organizations.
❖ The need for better management systems led to the development of what is now called “industrial engineering”.

Industrial Engineering
Definition of Industrial Engineering
❖ The formal definition of industrial engineering has been adopted by the Institute of Industrial Engineers (IIE):
“Industrial Engineering is concerned with the design, improvement, and installation of integrated systems of people, materials, information, equipment and energy. It draws upon specialized knowledge and skill in the mathematical, physical, and social sciences together with the principles and methods of engineering analysis and design to specify, predict, and evaluate the results to be obtained from such system”.
Scope ❖ The degree of industrial engineering is evidenced by the wide range of such
activities as research in biotechnology, development of new concepts of information processing, design of automated factories, and operation of incentive wage plans.
Chronology of Industrial Engineering
❖ Eli Whitney, showed that machine tools could make standardized parts to exact specifications.
❖ Frederick W. Taylor is known as “father of scientific management”. He is done potential improvements to be gained through analyzing the work content (minimum amount of work required to accomplish the task) of a job and designing the job for maximum efficiency. Taylor’s methods brought about significant and rapid increases in productivity.
❖ Frank B. and Lillian Gilbreth are husband and wife engineering team. They applied efficiency methods to their home and 12 children! Frank B. Gilbreth extended Taylor’s work considerably. Gilbreth’s primary contribution was the identification, analysis and measurement of fundamental motions involved in performing work.
❖ Henry Ford, used moving assembly line to make Model T unfinished product moved by conveyor past work station. Also He paid very well for 1911 ($5//day!)
❖ W. Edwards Deming, credited with teaching Jason quality control methods, used statistics to analyze process. His method involve workers in decisions.
❖ Henry L. Gantt, developed the Gantt chart. What is Gantt chart? Give an example of the Gantt Chart. It will be asked in Quiz 1.
❖ W.A. Shewhart developed the fundamental principles of statistical quality control in 1924.This was another important development in providing a scientific base to industrial engineering practise.
❖
Developments on IE❖ During the 1920s and 1930s much of fundamental work
was done on ❖ economic aspects of managerial decisions, ❖ inventory problems, ❖ incentive plans, ❖ factory layout problems, ❖ material handling problems, ❖ principles of organization.
Diversity
❖ Industrial engineering is a diverse (various) discipline concerned with the design, improvement, installation, and management of integrated systems of people, materials, and equipment for all kinds of manufacturing and service operations.
❖ Industrial engineering is concerned with performance measures and standards, research of new products and product applications, ways to improve use of scarce (limited) resources and many other problem solving adventures.
❖ An Industrial Engineer may be employed in almost any type of industry, business or institution, from retail establishments to manufacturing plants to government offices to hospitals. What is the role of the Industrial Engineering in a sector you choose? It will be asked in Final Exam.
❖ Because their skills can be used in almost any type of organization, and also industrial engineers are usually distributed among industries than other engineers.
❖ For example, industrial engineers work in insurance companies, banks, hospitals, retail organizations, airlines, government agencies, consulting firms, transportation, construction, public utilities, social service, electronics, personnel, sales, facilities design, manufacturing, processing, and warehousing.
Efficiency
❖ Industrial engineers determine the most effective ways for an organization to use the basic factors of production - people, machines, materials, and energy. They are more concerned with people and methods of business organization than engineers in other specialties.
❖ To solve organizational, production, and related problems most efficiently, industrial engineers design data processing systems and apply mathematical analysis such as operations research.
❖ They also develop management control systems to help in financial planning and cost analysis, design production planning and control systems to coordinate activities and control product quality, and design or improve systems for the physical distribution of goods and services.
❖ Industrial engineers conduct surveys to find plant locations with the best combination of raw materials, and transportation.
❖ They also develop wage and salary administration systems and job evaluation programs.
Activities
❖ Install data processing, management information, wage incentive systems. ❖ Develop performance standards, job evaluation, and wage and salary
programs. ❖ Research new products and product applications. ❖ Improve productivity through application of technology and human factors. ❖ Select operating processes and methods to do a task with proper tools and
equipment ❖ Design facilities, management systems, operating procedures ❖ Improve planning and allocation of limited resources ❖ Enhance plant environment and quality of people's working life ❖ Evaluate reliability and quality performance ❖ Implement office systems, procedures, and policies ❖ Analyze complex business problems by operations research ❖ Conduct organization studies, plant location surveys, and system
effectiveness studies❖ Study potential markets for goods and services, raw material sources, labor
supply, energy resources, financing, and taxes.
Impact of Related Developments
Impact of Related DevelopmentsThe evolution of the industrial and systems engineering profession has
been affected significantly by a number of related developments.
Impact of Operations Research
❖ The development of industrial engineering has been greatly influenced by the impact of an analysis approach called operations research.
❖ This approach originated in England and the United States during 2nd World War and was aimed at solving difficult war-related problems through the use of science, mathematics, behavioral science, probability theory, and statistics.
Impact of Related Developments (cont.)
Impact of Digital Computers
❖ Another development that had a significant impact on the IE profession is the digital computer. Digital computers permit the rapid and accurate handling of huge quantities of data, so permitting the IE to design systems for effectively managing and controlling large, complex operations.
❖ The digital computer also permits the IE to construct computer simulation models of manufacturing facilities in order to evaluate the effectiveness of alternative facility configurations.
❖ Computer simulation is emerging most widely used IE technique. The development and widespread utilization of personal computers is having an exciting impact on the practice of industrial engineering.
Impact of Related Developments (cont.)
Emergence of Service Industries
❖ In the early days of the industrial engineering profession, IE practice was applied almost fully in manufacturing organizations. After the 2nd World War there was a growing awareness that the principles and techniques of IE were also applicable in non-manufacturing environments.
❖ Thousands of Industrial Engineers are employed by government organizations to increase efficiency, reduce paperwork, design computerized management control systems, implement project management techniques, monitor the quality and reliability of vendor-supplied purchases, and for many other functions.
Challenges of Future
Challenges of the Future
❖ The world has a finite amount of nonrenewable resources. One of the major challenges for future engineers is to learn accomplish the engineer’s mission in recognition of these constraints.
❖ Another major challenge facing the engineering profess is to design systems and processes that are compatible with our natural environment.
Challenges of the Future (cont.)
❖ A major challenge that future engineers will encounter is that of designing products that are safe and reliable.
❖ There is also an increasing emphasis on improved quality.
❖ Perhaps the greatest challenge facing the engineering profession is to become involved in political issues and to provide assistance to lawmakers in design of social systems.
