The system self-sustainability is: # the degree at which the system can sustain itself without external support # the fraction of time in which the system is self-sustaining Self-sustainability is considered one of the "ilities" and is closely related to sustainability and availability. In the economics literature, a system that has the quality of being self-sustaining is also referred to as an autarky. ==Formal definition== 1. Let $E$ be a random variable that denotes the steady state number of external entities on which the system depends. Let $p(v)$ be the probability that the system depends on $v$ external entities, $p(v)=P(E=v)$. Then, the system self-sustainability, $S$, is $S=p(0)$. 2. Let $e\_t$ be the expected time during which the system is self-sustaining from time 0 up to time $t$. Then, the system self-sustainability is the steady state fraction of time in which it is self-sustaining, $S=\backslash lim\_\; /$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-sustainability」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
