Subtopic: what is a system? up

Quote: a system is division of a whole into components with properties and actions; it is descriptive but not inherent [»nygaK10_1986]
Quote: a system is a part of the world which someone chooses to see as made of components with properties and actions [»nygaK_1981]
Quote: a system is those aspects of an organization that can be described and analyzed by formal means [»holtAW3_1979]
Quote: a system consists of repeatable events and mutual constraints; an occurrence is one repetition of an event [»holtAW9_1968]
Quote: artifacts are regular and repetitive; reflect the purpose of their creator [»monoJ_1971]
Quote: a system is anything that interacts with its environment in a discrete fashion across a well-defined boundary [»lampL1_1989]
Quote: discrete state machines move from state to state; don't really exist but still a useful abstraction [»turiAM10_1950]

Subtopic: communication up

Quote: classification view of systems depends on a global perspective; communication view is localized and observable, like Plato's cave dwellers [»wegnP10_1986]
Quote: an environment and system communicate by changing values of state functions, e.g., voltages on wires [»lampL1_1989]

Subtopic: system as schema up

Quote: a system requires a schema, i.e., an a priori content and arrangement of parts; otherwise the unity is accidental [»kantI_1781, OK]
Quote: information is the values within the outcome of a process; a variable has multiple values, without changing the type of system [»loseRM3_1997]

Subtopic: foundation of a system up

Note: build a system by keyword, hierarchy, naming, or natural language; e.g., Roman vs. decimal numerals [»cbb_1990, OK]

Subtopic: compexity up

Quote: in a digital device, changing a single bit can have drastic consequences; a radical novelty of computers [»dijkEW12_1989]
Quote: man's creations can be more complex than the laws of nature; e.g., can predict tides but not when a system will overload [»dennPJ9_1980]

Subtopic: system as emergent property up

Quote: system is an emergent property of language; opposite to normal view [»cbb_1990, OK]
Quote: set-points and programs as cause of behavior are still the products of an intelligent act with foreknowledge of regularity [»turvMT_1984]
Quote: set-points such as body temperature are the result of system performance instead of the cause [»turvMT_1984]
Quote: the phoneme may be the consequence of perception instead of an intermediate form [»dreyHL_1979]
Quote: no part of the world is inherently a system [»nygaK_1981]
Quote: mind can not arise from mindless parts; either all matter is consciousness, or consciousness is distinct from matter [»wallAR_1870, OK]

Subtopic: resource up

Quote: a system theory should assume that all resources are limited; including space-time [»petrCA10_1979]
Quote: the absence of certain entities is a resource, e.g., the absence of printing on a piece of paper [»petrCA10_1979]
Quote: tools and jobs seek each other. Use the best tools for a job, and given the tools, find the best jobs [»zipfGK_1949]

Subtopic: systematic knowledge up

Quote: architectonic is the art of constructing a system or a systematic unity to our knowledge [»kantI_1781, OK]
Quote: a system is the unity of various knowledge under one idea, i.e., an a priori form of the whole

Subtopic: rules up

Quote: regular rules are easier to learn, use, describe, and implement [»maclBJ_1987]
Note: there are two kinds of rules: formal rules and regularities; Turing machines and words in a natural language [»cbb_1990, OK]

Subtopic: sets up

Quote: for aggregate success, members must be the same to the system (as observed) and different to the environment (for survival) [»weinGM_1979]
Quote: inanimate aggregates are common, e.g., books and ideas; they survive the destruction of copies or adherents [»weinGM_1979]

Subtopic: self-stabization up

Quote: a system is self-stabilizing when it is guaranteed to arrive and stay at good states from any initial state; i.e., closure and convergence [»schnM3_1993]

Subtopic: misuse of systems up

Quote: the mechanism of scientific management is wrong if applied without the essence [»taylRW_1911, OK]
Quote: you cannot run a business, or anything else involving people, on a theory
[»geneH_1984]
