3、方，設(shè)計(jì)者和級(jí)進(jìn)模不能完全實(shí)現(xiàn)熱處理過(guò)程中，材料特性、創(chuàng)意設(shè)計(jì)了解甚少的服務(wù)環(huán)境和設(shè)計(jì)思想。這些分歧將影響級(jí)進(jìn)模進(jìn)度。 因此，如果程序設(shè)計(jì)熱處理是在早期設(shè)計(jì)階段，目標(biāo)是縮短開(kāi)發(fā)時(shí)間、降低成本、穩(wěn)定質(zhì)量， 實(shí)現(xiàn)了從傳統(tǒng)的發(fā)展模式，同時(shí)并行順序?qū)?huì)實(shí)現(xiàn)。</p><p>　　并行工程是把電腦整合系統(tǒng)設(shè)計(jì)為載體,在每個(gè)階段開(kāi)始后，工廠要考慮，例如制造、熱處理、成本等因素，以避免錯(cuò)誤。并行方式駁回有缺陷的連續(xù)方式，給連續(xù)
