決策樹 / Decision Tree


「釋義」
決策樹是在已知各種情況發(fā)生概率的基礎(chǔ)上,通過構(gòu)成決策樹來求取凈現(xiàn)值的期望值大于等于零的概率,評估項目風(fēng)險,判斷其可行性的決策分析方法。
決策樹是直觀運用概率分析的一種圖解法。由于這種決策分支畫成圖形很像一棵樹的枝干,故稱決策樹。
「應(yīng)用場景」
在今天復(fù)雜、變動不居、各種力量相互依存的世界,沒人能完全準(zhǔn)確地預(yù)測未來。明晰地思考“灰色”問題有時很難。重要的是耐心打開思路、組建合適團隊,以人本主義精神分析所有行動選項。你可以粗略畫一個決策樹,列出所有備選行動和可能的結(jié)果;還可以指定挑戰(zhàn)者尋找漏洞,防止倉促下結(jié)論或陷入團體思維。
In today’s complex, fluid, interdependent world, none of us can predict the future with total accuracy. And it’s sometimes hard to think clearly about gray-area issues. What’s important is taking the time to open your mind, assemble the right team, and analyze your options through a humanist lens. You might sketch out a rough decision tree, listing all potential moves and all probable outcomes, or designate certain people to act as devil’s advocates to find holes in your thinking and prevent you from rushing to conclusions or succumbing to groupthink.
在做重要、艱難的決定時,你可能影響很多人的生活。第一個問題要求你充分認(rèn)識這一現(xiàn)實。
When you make important, difficult decisions, you affect many people’s lives and livelihoods. The first question asks you to grapple hard with that reality.
