1、離散制造業(yè)概述HistoryofDiscreteMfg什么是離散制造業(yè)?制造業(yè)按其產(chǎn)品制造工藝過程特點總體上可概括為流程制造和離散制造。相對于連續(xù)制造，離散制造的產(chǎn)品往往由多個零件經(jīng)過一系列并不連續(xù)的工序的加工最終裝配而成。?離散制造行業(yè)–產(chǎn)品為構(gòu)造型，生產(chǎn)過程只有形狀的改變，沒有質(zhì)變–包括計算機、家電、汽車、航天和機械設(shè)備?流程制造行業(yè)–產(chǎn)品為非構(gòu)造型，即通過化學(xué)分解、合成或生物發(fā)酵使物質(zhì)改變成另外一種物質(zhì)–鋼鐵、有色冶金、化肥、石化、化工等?離散、流程混合行業(yè)–產(chǎn)品前半段為流程，后半段為離散。產(chǎn)品成本中包裝占較大比例–制藥、食品加工、酒、煙草等?2
