When a network performs poorly, its users often complain to the folks running it, demanding improvements. To improve the performance, the operators must first determine exactly what is going on. To find out what is really happening, the operators must make measurements. In this section we will lo..

摘要:敏捷制造認(rèn)識(shí)到不穩(wěn)定的市場(chǎng),并試圖通過滿足客戶不斷變化的需求來提高公司的競(jìng)爭(zhēng)力。在這樣做的同時(shí),參與敏捷制造的競(jìng)爭(zhēng)者需要同制造供應(yīng)商,競(jìng)爭(zhēng)對(duì)手合作,或者與這兩者同時(shí)合作。由于市場(chǎng)的內(nèi)在性質(zhì)是不穩(wěn)定的和復(fù)雜的,對(duì)于經(jīng)營變化的潛在能力,不確定性和復(fù)雜性是必不可少的。這種首要潛在能力的支柱是人們..
