65-556: Industrial engineering is an engineering profession that is concerned with the optimization of complex processes , systems , or organizations by developing, improving and implementing integrated systems of people, money, knowledge, information and equipment. Industrial engineering is central to manufacturing operations. Industrial engineers use specialized knowledge and skills in the mathematical, physical , and social sciences , together with engineering analysis and design principles and methods, to specify, predict, and evaluate

130-461: A 5,000 dollar incentive with an additional 5,000 dollars once that money was exhausted for the person that was able to accurately produce arms for the government. Because the cotton gin had not brought Whitney the rewards he believed it promised, he accepted the offer. Although the contract was for one year, Whitney did not deliver the arms until 1809, using multiple excuses for the delay. Recently, historians have found that during 1801–1806, Whitney took

195-439: A broad math and science foundation spanning chemistry , physics , mechanics (i.e., statics, kinematics, and dynamics), materials science , computer science , electronics/circuits, engineering design , and the standard range of engineering mathematics (i.e., calculus , linear algebra , differential equations , statistics ). For any engineering undergraduate program to be accredited, regardless of concentration, it must cover

260-489: A contract to manufacture muskets in 1798 were mostly monetary. By the late 1790s, Whitney was on the verge of bankruptcy and the cotton gin litigation had left him deeply in debt . His New Haven cotton gin factory had burned to the ground, and litigation sapped his remaining resources. The French Revolution had ignited new conflicts between Great Britain, France, and the United States. The new American government, realizing

325-429: A dominant economic force, and slavery was sustained as a key institution of Southern society. Eli Whitney has often been incorrectly credited with inventing the idea of interchangeable parts, which he championed for years as a maker of muskets ; however, the idea predated Whitney, and Whitney's role in it was one of promotion and popularizing, not invention. Successful implementation of the idea eluded Whitney until near

390-665: A fair amount of standardization of artillery pieces, although not true interchangeability of parts. He inspired others, including Honoré Blanc and Louis de Tousard , to work further on the idea, and on shoulder weapons as well as artillery. In the 19th century these efforts produced the "armory system," or American system of manufacturing . Certain other New Englanders, including Captain John H. Hall and Simeon North , arrived at successful interchangeability before Whitney's armory did. The Whitney armory finally succeeded not long after his death in 1825. The motives behind Whitney's acceptance of

455-443: A farm laborer and school teacher to save money. He prepared for Yale at Leicester Academy (later Becker College ) and under the tutelage of Rev. Elizur Goodrich of Durham , Connecticut, he entered Yale in the fall of 1789 and graduated Phi Beta Kappa in 1792. Whitney expected to study law but, finding himself short of funds, accepted an offer to go to South Carolina as a private tutor. Instead of reaching his destination, he

520-449: A gin which substituted circular saws for the spikes) and their cotton gin company went out of business in 1797. One oft-overlooked point is that there were drawbacks to Whitney's first design. There are claims that the use of wires rather than pegs was proposed by Mrs. Greene, but these are disputed. After validation of the patent, the legislature of South Carolina voted $ 50,000 for the rights for that state, while North Carolina levied

585-810: A largely similar span of such foundational work – which also overlaps heavily with the content tested on one or more engineering licensure exams in most jurisdictions. The coursework specific to IE entails specialized courses in areas such as optimization , applied probability , stochastic modeling, design of experiments , statistical process control , simulation , manufacturing engineering , ergonomics / safety engineering , and engineering economics . Industrial engineering elective courses typically cover more specialized topics in areas such as manufacturing , supply chains and logistics , analytics and machine learning , production systems , human factors and industrial design , and service systems . Process (engineering) Semiconductor process engineers face

650-467: A license tax for five years, from which about $ 30,000 was realized. There is a claim that Tennessee paid about $ 10,000. While the cotton gin did not earn Whitney the fortune he had hoped for, it did give him fame. It has been argued by some historians that Whitney's cotton gin was an important if unintended cause of the American Civil War. After Whitney's invention, the plantation slavery industry

715-439: A month after his 59th birthday. He left a widow and his four children behind. One of his offspring, Eli Whitney III (known as Eli Whitney Jr.), was instrumental in building New Haven, Connecticut's waterworks. During the course of his illness, he reportedly invented and constructed several devices to mechanically ease his pain.

ISBN   0-7506-6507-6 . Eli Whitney Eli Whitney Jr. (December 8, 1765 – January 8, 1825) was an American inventor, widely known for inventing the cotton gin in 1793, one of the key inventions of

845-431: A process, system, or organization operates. In fact, the industrial in industrial engineering means the industry in its broadest sense. People have changed the term industrial to broader terms such as industrial and manufacturing engineering , industrial and systems engineering , industrial engineering and operations research , industrial engineering and management . Industrial engineering has many sub-disciplines,

910-456: A separate program in 1909 through the efforts of Hugo Diemer . The first doctoral degree in industrial engineering was awarded in 1933 by Cornell University . In 1912, Henry Laurence Gantt developed the Gantt chart , which outlines actions the organization along with their relationships. This chart opens later form familiar to us today by Wallace Clark . With the development of assembly lines ,

975-495: Is a general consensus among historians that the roots of the industrial engineering profession date back to the Industrial Revolution . The technologies that helped mechanize traditional manual operations in the textile industry including the flying shuttle , the spinning jenny , and perhaps most importantly the steam engine generated economies of scale that made mass production in centralized locations attractive for

1040-411: Is also a significant milestone in the field. Engineering is traditionally decompositional. To understand the whole of something, it is first broken down into its parts. One masters the parts, then puts them back together to create a better understanding of how to master the whole. The approach of industrial and systems engineering (ISE) is opposite; any one part cannot be understood without the context of

1105-432: Is different in that it is based on discrete variable math, whereas all other engineering is based on continuous variable math. We emphasize the use of linear algebra and difference equations, as opposed to the use of differential equations which are so prevalent in other engineering disciplines. This emphasis becomes evident in optimization of production systems in which we are sequencing orders, scheduling batches, determining

1170-433: Is generally credited as being the father of the industrial engineering discipline. He earned a degree in mechanical engineering from Stevens Institute of Technology and earned several patents from his inventions. His books, Shop Management and The Principles of Scientific Management , which were published in the early 1900s, were the beginning of industrial engineering. Improvements in work efficiency under his methods

1235-477: Is the branch of Engineering most closely related to human resources in that we apply social skills to work with all types of employees, from engineers to salespeople to top management. One of the main focuses of an Industrial Engineer is to improve the working environments of people – not to change the worker, but to change the workplace." "All engineers, including Industrial Engineers, take mathematics through calculus and differential equations. Industrial Engineering

1300-475: Is the use of ultra-violet photolithography which is then followed by wet etching , the process of creating an IC pattern that is transferred onto an organic coating and etched onto the underlying semiconductor chip. Other examples include the ion implantation of dopant species to tailor the electrical properties of a semiconductor chip and the electrochemical deposition of metallic interconnects (e.g. electroplating ). Process Engineers are generally involved in

1365-619: The African slavery system in the Southern United States to become more sustainable at a critical point in its development. Whitney applied for the patent for his cotton gin on October 28, 1793, and received the patent (later numbered as X72) on March 14, 1794, but it was not validated until 1807. Whitney and his partner, Miller, did not intend to sell the gins. Rather, like the proprietors of gristmills and sawmills , they expected to charge farmers for cleaning their cotton – two-fifths of

1430-531: The Industrial Revolution that shaped the economy of the Antebellum South . Whitney's invention made upland short cotton into a profitable crop, which strengthened the economic foundation of slavery in the United States and prolonged the institution. Despite the social and economic impact of his invention, Whitney lost much of his profits in legal battles over patent infringement for the cotton gin. Thereafter, he turned his attention to securing contracts with

1495-783: The CPRET acronym to be used as name and mnemonic for this definition. The purpose of the following examples is to illustrate the definitions with concrete cases. These examples come from the Engineering field but also from other fields to show that the CPRET definition of processes is not limited to the System Engineering context. Examples of processes Examples of environment Examples of mission Examples of constraints Examples of products Examples of resources Examples of elements as inputs Examples of transformations The CPRET formalized definition systematically addresses

1560-493: The Industrial Revolution to establish and implement factory systems. The efforts of James Watt and Matthew Boulton led to the first integrated machine manufacturing facility in the world, including the application of concepts such as cost control systems to reduce waste and increase productivity and the institution of skills training for craftsmen. Charles Babbage became associated with industrial engineering because of

1625-594: The North the adoption of interchangeable parts revolutionized the manufacturing industry, contributing greatly to the U.S. victory in the Civil War . The cotton gin is a mechanical device that removes the seeds from cotton, a process that had previously been extremely labor-intensive. The word gin is short for engine. While staying at Mulberry Grove, Whitney constructed several ingenious household devices which led Mrs Greene to introduce him to some businessmen who were discussing

1690-530: The United States for another 70 years. Before the 1790s, slave labor was primarily employed in growing rice, tobacco, and indigo , none of which were especially profitable anymore. Neither was cotton, due to the difficulty of seed removal. But with the invention of the gin, growing cotton with slave labor became highly profitable – the chief source of wealth in the American South, and the basis of frontier settlement from Georgia to Texas. " King Cotton " became

1755-470: The bachelor, masters, and doctoral level. In the United States, the undergraduate degree earned is either a bachelor of science (B.S.) or a bachelor of science and engineering (B.S.E.) in industrial engineering (IE). In South Africa , the undergraduate degree is a bachelor of engineering (BEng). Variations of the title include Industrial & Operations Engineering (IOE), and Industrial & Systems Engineering (ISE or ISyE). The typical curriculum includes

1820-546: The concepts he introduced in his book On the Economy of Machinery and Manufacturers which he wrote as a result of his visits to factories in England and the United States in the early 1800s. The book includes subjects such as the time required to perform a specific task, the effects of subdividing tasks into smaller and less detailed elements, and the advantages to be gained from repetitive tasks. Eli Whitney and Simeon North proved

1885-407: The desirability of a machine to separate the short staple upland cotton from its seeds, work that was then done by hand at the rate of a pound of lint a day. In a few weeks Whitney produced a model. The cotton gin was a wooden drum stuck with hooks that pulled the cotton fibers through a mesh. The cotton seeds would not fit through the mesh and fell outside. Whitney occasionally told a story wherein he

1950-772: The development of decision support systems in supply such as material requirements planning (MRP), one can emphasize the timing issue (inventory, production, compounding, transportation, etc.) of industrial organization. Israeli scientist Dr. Jacob Rubinovitz installed the CMMS program developed in IAI and Control-Data (Israel) in 1976 in South Africa and worldwide. In the 1970s, with the penetration of Japanese management theories such as Kaizen and Kanban , Japan realized very high levels of quality and productivity. These theories improved issues of quality, delivery time, and flexibility. Companies in

2080-407: The elements of human motion into 18 basic elements called therbligs . This development permitted analysts to design jobs without knowledge of the time required to do a job. These developments were the beginning of a much broader field known as human factors or ergonomics . In 1908, the first course on industrial engineering was offered as an elective at Pennsylvania State University , which became

2145-571: The end of his life, occurring first in others' armories. Attempts at interchangeability of parts can be traced back as far as the Punic Wars through both archaeological remains of boats now in Museo Archeologico Baglio Anselmi and contemporary written accounts. In modern times the idea developed over decades among many people. An early leader was Jean-Baptiste Vaquette de Gribeauval , an 18th-century French artillerist who created

2210-399: The factory of Henry Ford (1913) accounted for a significant leap forward in the field. Ford reduced the assembly time of a car from more than 700 hours to 1.5 hours. In addition, he was a pioneer of the economy of the capitalist welfare ("welfare capitalism") and the flag of providing financial incentives for employees to increase productivity. In 1927, the then Technische Hochschule Berlin

2275-605: The famed evangelist Jonathan Edwards , daughter of Pierpont Edwards , head of the Democratic Party in Connecticut, and first cousin of Yale's president, Timothy Dwight , the state's leading Federalist , further tied him to Connecticut's ruling elite . In a business dependent on government contracts, such connections were essential to success. Whitney died of prostate cancer on January 8, 1825, in New Haven, Connecticut, just

2340-485: The feasibility of the notion of interchangeable parts in the manufacture of muskets and pistols for the US Government. Under this system, individual parts were mass-produced to tolerances to enable their use in any finished product. The result was a significant reduction in the need for skill from specialized workers, which eventually led to the industrial environment to be studied later. Frederick Taylor (1856–1915)

2405-476: The first milling machine circa 1818. Subsequent work by other historians (Woodbury; Smith; Muir; Battison [cited by Baida ]) suggests that Whitney was among a group of contemporaries all developing milling machines at about the same time (1814 to 1818), and that the others were more important to the innovation than Whitney was. (The machine that excited Roe may not have been built until 1825, after Whitney's death.) Therefore, no one person can properly be described as

2470-512: The first time. The concept of the production system had its genesis in the factories created by these innovations. It has also been suggested that perhaps Leonardo da Vinci was the first industrial engineer because there is evidence that he applied science to the analysis of human work by examining the rate at which a man could shovel dirt around the year 1500. Others also state that the industrial engineering profession grew from Charles Babbage’s study of factory operations and specifically his work on

2535-471: The government complained that Whitney's price per musket compared unfavorably with those produced in government armories, he was able to calculate an actual price per musket by including fixed costs such as insurance and machinery , which the government had not accounted for. He thus made early contributions to both the concepts of cost accounting , and economic efficiency in manufacturing. Machine tool historian Joseph W. Roe credited Whitney with inventing

2600-456: The government in the manufacture of muskets for the newly formed United States Army. He continued making arms and inventing until his death in 1825. Whitney was born in Westborough , Massachusetts , on December 8, 1765, the eldest child of Eli Whitney Sr., a prosperous farmer, and his wife Elizabeth Fay, also of Westborough. The younger Eli was famous during his lifetime and after his death by

Industrial engineering degrees accredited within any member country of the Washington Accord enjoy equal accreditation within all other signatory countries, thus allowing engineers from one country to practice engineering professionally in any other. Universities offer degrees at

2795-536: The inventor of the milling machine. Despite his humble origins, Whitney was keenly aware of the value of social and political connections. In building his arms business, he took full advantage of the access that his status as a Yale alumnus gave him to other well-placed graduates, such as Oliver Wolcott Jr. , Secretary of the Treasury (class of 1778), and James Hillhouse , a New Haven developer and political leader. His 1817 marriage to Henrietta Edwards, granddaughter of

2860-415: The manufacture of straight pins in 1832 . However, it has been generally argued that these early efforts, while valuable, were merely observational and did not attempt to engineer the jobs studied or increase overall output. Adam Smith's concepts of Division of Labour and the "Invisible Hand" of capitalism introduced in his treatise The Wealth of Nations motivated many of the technological innovators of

2925-400: The money and headed into South Carolina in order to profit from the cotton gin. Although Whitney's demonstration of 1801 appeared to show the feasibility of creating interchangeable parts, Merritt Roe Smith concludes that it was "staged" and "duped government authorities" into believing that he had been successful. The charade gained him time and resources toward achieving that goal. When

3055-504: The name "Eli Whitney", though he was technically Eli Whitney Jr. His son, born in 1820, also named Eli, was known during his lifetime and afterward by the name "Eli Whitney Jr." Whitney's mother, Elizabeth Fay, died in 1777, when he was 11. At age 14 he operated a profitable nail manufacturing operation in his father's workshop during the Revolutionary War . Because his stepmother opposed his wish to attend college, Whitney worked as

3120-817: The need to prepare for war, began to rearm. The War Department issued contracts for the manufacture of 10,000 muskets. Whitney, who had never made a gun in his life, obtained a contract in January 1798 to deliver 10,000 to 15,000 muskets in 1800. He had not mentioned interchangeable parts at that time. Ten months later, the Treasury Secretary, Oliver Wolcott Jr. , sent him a "foreign pamphlet on arms manufacturing techniques," possibly one of Honoré Blanc's reports, after which Whitney first began to talk about interchangeability. In May 1798, Congress voted for legislation that would use 800,000 dollars in order to pay for small arms and cannons in case war with France erupted. It offered

Note: process definition and modeling are interdependent notions but different the one from the other. This definition requires a process description to include the Constraints, Products, Resources, Input Elements and Transformations. This leads to

3315-458: The results obtained from systems and processes. Several industrial engineering principles are followed in the manufacturing industry to ensure the effective flow of systems, processes, and operations. These include: These principles allow the creation of new systems , processes or situations for the useful coordination of labor , materials and machines and also improve the quality and productivity of systems, physical or social. Depending on

Common semiconductor devices include Integrated Circuits (ICs), Light-Emitting Diodes (LEDs), solar cells , and solid-state lasers . To produce these and other semiconductor devices, semiconductor process engineers rely heavily on interconnected physical and chemical processes. A prominent example of these combined processes

3510-405: The value, paid in cotton. Resentment at this scheme, the mechanical simplicity of the device and the primitive state of patent law , made infringement inevitable. Whitney and Miller could not build enough gins to meet demand, so gins from other makers found ready sale. Ultimately, patent infringement lawsuits consumed the profits (one patent, later annulled, was granted in 1796 to Hogden Holmes for

3575-595: The war. The American Institute of Industrial Engineering was formed in 1948. The early work by F. W. Taylor and the Gilbreths was documented in papers presented to the American Society of Mechanical Engineers as interest grew from merely improving machine performance to the performance of the overall manufacturing process, most notably starting with the presentation by Henry R. Towne (1844–1924) of his paper The Engineer as An Economist (1886). From 1960 to 1975, with

3640-509: The west realized the great impact of Kaizen and started implementing their own continuous improvement programs. W. Edwards Deming made significant contributions in the minimization of variance starting in the 1950s and continuing to the end of his life. In the 1990s, following the global industry globalization process, the emphasis was on supply chain management and customer-oriented business process design. The theory of constraints , developed by Israeli scientist Eliyahu M. Goldratt (1985),

3705-866: The whole system. Changes in one part of the system affect the entire system, and the role of a single part is to better serve the whole system. Also, industrial engineering considers the human factor and its relation to the technical aspect of the situation and all of the other factors that influence the entire situation, while other engineering disciplines focus on the design of inanimate objects. "Industrial Engineers integrate combinations of people, information, materials, and equipment that produce innovative and efficient organizations. In addition to manufacturing, Industrial Engineers work and consult in every industry, including hospitals, communications, e-commerce, entertainment, government, finance, food, pharmaceuticals, semiconductors, sports, insurance, sales, accounting, banking, travel, and transportation." "Industrial Engineering

3770-489: Was Phineas Miller, another Connecticut migrant and Yale graduate (class of 1785), who would become Whitney's business partner. Whitney is most famous for two innovations which came to have significant impacts on the United States in the mid-19th century: the cotton gin (1793) and his advocacy of interchangeable parts . In the South, the cotton gin revolutionized the way cotton was harvested and reinvigorated slavery. Conversely, in

It became the U.S.'s chief export, representing over half the value of U.S. exports from 1820 to 1860. Whitney believed that his cotton gin would reduce the demand for enslaved labor and would help hasten the end of southern slavery. Paradoxically, the cotton gin, a labor-saving device, helped preserve and prolong slavery in

3900-405: Was based on improving work methods, developing of work standards, and reduction in time required to carry out the work. With an abiding faith in the scientific method, Taylor did many experiments in machine shop work on machines as well as men. Taylor developed "time study" to measure time taken for various elements of a task and then used the study observations to reduce the time further. Time study

3965-588: Was convinced to visit Georgia. In the closing years of the 18th century, Georgia was a magnet for New Englanders seeking their fortunes (its Revolutionary-era governor had been Lyman Hall , a migrant from Connecticut). When he initially sailed for South Carolina, among his shipmates were the widow ( Catherine Littlefield Greene ) and family of the Revolutionary hero Gen. Nathanael Greene of Rhode Island. Mrs. Greene invited Whitney to visit her Georgia plantation, Mulberry Grove . Her plantation manager and husband-to-be

The husband-and-wife team of Frank Gilbreth (1868–1924) and Lillian Gilbreth (1878–1972) was the other cornerstone of the industrial engineering movement whose work is housed at Purdue University School of Industrial Engineering. They categorized

A single cotton gin could generate up to 55 pounds (25 kg) of cleaned cotton daily. This contributed to the economic development of the Southern United States , a prime cotton growing area; some historians believe that this invention allowed for

4160-531: Was rejuvenated, eventually culminating in the Civil War. The cotton gin transformed Southern agriculture and the national economy. Southern cotton found ready markets in Europe and in the burgeoning textile mills of New England . Cotton exports from the U.S. boomed after the cotton gin's appearance – from less than 500,000 pounds (230,000 kg) in 1793 to 93 million pounds (42,000,000 kg) by 1810. Cotton
