Jidoka
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 throug ...

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 required res ...

Kaizen
is concept referring to business activities that continuously improve all functions and involve all employees from the CEO to the assembly line workers. ''Kaizen'' also applies to processes, such as purchasing and logistics, that cross organizational boundaries into the supply chain. It has been applied in healthcare, psychotherapy, life coaching, government, and banking. By improving standardized programs and processes, kaizen aims to eliminate waste and redundancies (lean manufacturing). Kaizen was first practiced in Japanese businesses after World War II, influenced in part by American business and quality-management teachers, and most notably as part of The Toyota Way. It has since spread throughout the world and has been applied to environments outside of business and productivity. Overview The Japanese word means 'change for better', with the inherent meaning of either 'continuous' or 'philosophy' in Japanese dictionaries and in everyday use. The word refers to any ...

Andon (manufacturing)
Signboard In manufacturing, andon ( ja, アンドン or あんどん or 行灯) is a system which notifies managerial, maintenance, and other workers of a quality or process problem. The alert can be activated manually by a worker using a pullcord or button or may be activated automatically by the production equipment itself. The system may include a means to pause production so the issue can be corrected. Some modern alert systems incorporate audio alarms, text, or other displays; stack lights are among the most commonly used. “Andon” is a loanword from Japanese, originally meaning ''paper lantern''; Japanese manufacturers began its quality-control usage. Details An andon system is one of the principal elements of the Jidoka quality control method pioneered by Toyota as part of the Toyota Production System and therefore now part of the lean production approach. The principle of Andon works as such: if there are any production issues happening in Production line, the aff ...

Radical (Chinese Character)
A Chinese radical () or indexing component is a graphical component of a Chinese character under which the character is traditionally listed in a Chinese dictionary. This component is often a semantic indicator similar to a morpheme, though sometimes it may be a phonetic component or even an artificially extracted portion of the character. In some cases the original semantic or phonological connection has become obscure, owing to changes in character meaning or pronunciation over time. The English term "radical" is based on an analogy between the structure of characters and inflection of words in European languages. Radicals are also sometimes called "classifiers", but this name is more commonly applied to grammatical classifiers (measure words). History In the earliest Chinese dictionaries, such as the '' Erya'' (3rd century BC), characters were grouped together in broad semantic categories. Because the vast majority of characters are phono-semantic compounds (), comb ...

Kanji
are the logographic Chinese characters taken from the Chinese family of scripts, Chinese script and used in the writing of Japanese language, Japanese. They were made a major part of the Japanese writing system during the time of Old Japanese and are still used, along with the subsequently-derived syllabic scripts of ''hiragana'' and ''katakana''. The characters have Japanese pronunciation, pronunciations; most have two, with one based on the Chinese sound. A few characters were invented in Japan by constructing character components derived from other Chinese characters. After World War II, Japan made its own efforts to simplify the characters, now known as shinjitai, by a process similar to China's simplified Chinese characters, simplification efforts, with the intention to increase literacy among the common folk. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characte ...

Automation
Automation describes a wide range of technologies that reduce human intervention in processes, namely by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern factories, airplanes, and ships typically use combinations of all of these techniques. The benefit of automation includes labor savings, reducing waste, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision. Automation includes the use of various equipment and control systems such as machinery, processes in factories, boilers, and heat-treating ovens, switching on telephone networks, steering, and stabilization of ships, aircraft, and other applications and vehicles with reduced hu ...

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 autonomy ...

Sino-Japanese Vocabulary
Sino-Japanese vocabulary, also known as refers to Japanese vocabulary that had originated in Chinese or were created from elements borrowed from Chinese. Some grammatical structures and sentence patterns can also be identified as Sino-Japanese. Sino-Japanese vocabulary is referred to in Japanese as , meaning 'Chinese words'. ''Kango'' is one of three broad categories into which the Japanese vocabulary is divided. The others are native Japanese vocabulary (''yamato kotoba'') and borrowings from other, mainly Western languages (''gairaigo''). It is estimated that approximately 60% of the words contained in the modern written Japanese dictionary are ''kango'', with about 18%–20% of words being used in common speech. The usage of such ''Kango'' words also increases when they are used in formal or literary contexts, or to express abstract or complex ideas. ''Kango'', the use of Chinese-derived words in Japanese, is to be distinguished from ''kanbun'', which is historical Literary Ch ...

Lean 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 Japa ...

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 indeclin ...
