Production information board updating maintenance 生產(chǎn)部看板的更新維護(hù)。
Record / analyze / update maintenance records of production machines 紀(jì)錄,分析,更新生產(chǎn)設(shè)備維修記錄。
Both temporal and spatial views are taken account into creating sparse position number , lifespan and other node properties for every document node in the tree document structures of z - office . and a new algorithm based document update maintenance is proposed and implemented in the system . with the support of these works , z - office can retrieve all versions efficiently and quickly 具體來說就是利用空間性和時(shí)間性的概念,針對(duì)z - office文檔,為其樹形文檔結(jié)構(gòu)上的每個(gè)節(jié)點(diǎn)位置進(jìn)行稀疏編碼并賦予節(jié)點(diǎn)生存區(qū)間以及其它一些附屬信息,然后在文檔增量存儲(chǔ)上使用了本文提出的文檔更新維護(hù)算法,使得改進(jìn)后的方案不需要往前或往后推算即可直接獲取任意版本的z - office文檔。
