Autonomation
Autonomation describes a feature of machine design to effect the principle of （じどうか jidouka), used in the Toyota Production System (TPS) and lean manufacturing. It may be described as "intelligent automation" or "automation with a human touch". This type of automation implements some supervisory functions rather than production functions. At Toyota, this usually means that if an abnormal situation arises, the machine stops and the worker will stop the production line. It is a quality control process that applies the following four principles: # Detect the abnormality. # Stop. # Fix or correct the immediate condition. # Investigate the root cause and install a countermeasure. Autonomation aims to prevent the production of defective products, eliminate overproduction and focus attention on understanding the problems and ensuring that they do not reoccur. Purpose and implementation Shigeo Shingo calls autonomation "pre-automation". It separates workers from machines throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota Production System
The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices. The TPS is a management system that organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers. The system is a major precursor of the more generic " lean manufacturing". Taiichi Ohno and Eiji Toyoda, Japanese industrial engineers, developed the system between 1948 and 1975. Originally called " just-in-time production", it builds on the approach created by the founder of Toyota, Sakichi Toyoda, his son Kiichiro Toyoda, and the engineer Taiichi Ohno. The principles underlying the TPS are embodied in The Toyota Way. Goals The main objectives of the TPS are to design out overburden ( muri) and inconsistency ( mura), and to eliminate waste ( muda). The most significant effects on process value delivery are achieved by designing a process capable of delivering the require ...

Sakichi Toyoda
was a Japanese inventor and industrialist. He was born in Kosai, Shizuoka. The son of a farmer and sought-after carpenter, he started the Toyoda family companies. His son, Kiichiro Toyoda, would later establish Japan's largest automaker, Toyota. Toyoda is referred to as the "King of Japanese Inventors". Toyoda Automatic Loom Works Toyoda Automatic Loom Works was the engineering manufacturing company established by Sakichi Toyoda in 1926. It earned him the moniker of father of the Japanese industrial revolution. He is also the founder of Toyota Industries Co., Ltd. Toyoda invented and innovated numerous textile-focused weaving devices, introducing innovative fueling systems used to power his Toyoda-branded machines. His most famous invention was the automatic power loom in which he implemented the principle of '' Jidoka'' ( autonomous automation). The principle of ''Jidoka'', which means that the machine stops itself when a problem occurs, became later a part of the Toyota P ...

Semi-automation
Semi-automation is a process or procedure that is performed by the combined activities of man and machine with both human and machine steps typically orchestrated by a centralized computer controller. Within manufacturing, production processes may be fully manual, semi-automated, or fully automated. In this case, semi-automation may vary in its degree of manual and automated steps. Semi-automated manufacturing processes are typically orchestrated by a computer controller which sends messages to the worker at the time in which he/she should perform a step. The controller typically waits for feedback that the human performed step has been completed via either a human-machine interface or via electronic sensors distributed within the process. Controllers within semi-automated processes may either directly control machinery or send signals to machinery distributed within the process. Centralized computer controllers within semi-automated processes orchestrate processes by instructin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shigeo Shingo
was a Japanese industrial engineer who was considered as the world’s leading expert on manufacturing practices and the Toyota Production System. Life and work After having worked as a technician specializing in fusions at the Taiwanese railways in Taipei, at the end of the World War II, in 1945, he started to work at the Japan Management Association (JMA) ( :ja:日本能率協会) in Tokyo, becoming a consultant focused on the improvement of factory management. Gathering tips from the improvement experiences in the field he had in 1950 at Toyo Ind. (now Mazda) and in 1957 at the sites in Hiroshima of the Mitsubishi Heavy Industries, since 1969 Shingō got involved in some actions in Toyota Motor Corporation ( Toyota) for the reduction of set-up time (change of dies) of pressing machines which took him to the formulation of a specific technique based on operational analysis, which shortened set-up times from 1 to 2 hours (or even half a day) per each exchange of dies to a rapid ...

Overproduction
In economics, overproduction, oversupply, excess of supply or glut refers to excess of supply over demand of products being offered to the market. This leads to lower prices and/or unsold goods along with the possibility of unemployment. The demand side equivalent is underconsumption; some consider supply and demand two sides to the same coin – excess supply is only relative to a given demand, and insufficient demand is only relative to a given supply – and thus consider overproduction and underconsumption equivalent. Overproduction is often attributed as due to previous overinvestment – creation of excess productive capacity, which must then either lie idle (or under capacity), which is un profitable, or produce an excess supply. Explanation Overproduction is the accumulation of unsalable inventories in the hands of businesses. Overproduction is a relative measure, referring to the excess of production over consumption. The tendency for an overproduction of commodit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poka-yoke
is a Japanese term that means "mistake-proofing" or "inadvertent error prevention". A poka-yoke is any mechanism in a process that helps an equipment operator avoid (''yokeru'') mistakes (''poka'') and defects by preventing, correcting, or drawing attention to human errors as they occur. The concept was formalized, and the term adopted, by Shigeo Shingo as part of the Toyota Production System. Etymology Poka-yoke was originally ''baka-yoke'', but as this means "fool-proofing" (or " idiot-proofing") the name was changed to the milder ''poka-yoke''. Poka-yoke is derived from ''poka o yokeru'' (ポカを避ける), a term in shogi that means avoiding an unthinkably bad move. Usage More broadly, the term can refer to any behavior-shaping constraint designed into a process to prevent incorrect operation by the user. A simple poka-yoke example is demonstrated when a driver of the car equipped with a manual gearbox must press on the clutch pedal (a process step, therefore a poka-yoke) ...

Taiichi Ohno
was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which inspired Lean Manufacturing in the U.S. He devised the seven wastes (or muda in Japanese) as part of this system. He wrote several books about the system, including ''Toyota Production System: Beyond Large-Scale Production''. Life Born in 1912 in Dalian, China, and a graduate of the Nagoya Technical High School (Japan), he joined the Toyoda family's Toyoda Spinning upon graduation in 1932 during the Great Depression thanks to the relations of his father to Kiichiro Toyoda, the son of Toyota's founding father Sakichi Toyoda. He moved to the Toyota motor company in 1943 where he worked as a shop-floor supervisor in the engine manufacturing shop of the plant, and gradually rose through the ranks to become an executive. Influence Ohno's principles influenced areas outside of manufacturing, and have been extended into the service arena. For example, the fi ...

Just-in-time Manufacturing
Lean manufacturing is a production method aimed primarily at reducing times within the production system as well as response times from suppliers and to customers. It is closely related to another concept called just-in-time manufacturing (JIT manufacturing in short). Just-in-time manufacturing tries to match production to demand by only supplying goods which have been ordered and focuses on efficiency, productivity (with a commitment to continuous improvement) and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow and throughput times by further eliminating activities which do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service. Lean manufacturing is particularly related to the operational model implemented in the post-war 1950s and 1960s by the Japan ...

Loan Word
A loanword (also loan word or loan-word) is a word at least partly assimilated from one language (the donor language) into another language. This is in contrast to cognates, which are words in two or more languages that are similar because they share an etymological origin, and calques, which involve translation. Loanwords from languages with different scripts are usually transliterated (between scripts), but they are not translated. Additionally, loanwords may be adapted to phonology, phonotactics, orthography, and morphology of the target language. When a loanword is fully adapted to the rules of the target language, it is distinguished from native words of the target language only by its origin. However, often the adaptation is incomplete, so loanwords may conserve specific features distinguishing them from native words of the target language: loaned phonemes and sound combinations, partial or total conserving of the original spelling, foreign plural or case forms or indecli ...

Autonomous
In developmental psychology and moral, political, and bioethical philosophy, autonomy, from , ''autonomos'', from αὐτο- ''auto-'' "self" and νόμος ''nomos'', "law", hence when combined understood to mean "one who gives oneself one's own law" is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a (relatively high) level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Sociology In the sociology of knowledge, a controversy over the boundaries of autonomy inhibited analysis of any concept beyond relative autonom ...
