【摘要】：以串聯(lián)可修生產(chǎn)線緩沖庫(kù)存和可靠性為研究對(duì)象,基于生產(chǎn)協(xié)同性,建立了設(shè)備故障率服從指數(shù)分布、維修時(shí)間服從對(duì)數(shù)正態(tài)分布的串聯(lián)可修生產(chǎn)線結(jié)構(gòu)模型。根據(jù)生產(chǎn)線可靠性的不同要求,以平均修復(fù)時(shí)間的不同置信上限作為修復(fù)時(shí)間提出了最小緩沖庫(kù)存、最大緩存的計(jì)算公式和對(duì)庫(kù)存均衡條件進(jìn)行了分析,通過實(shí)例驗(yàn)證了計(jì)算公式的有效性。繼而推導(dǎo)出生產(chǎn)線可靠性與設(shè)備維修時(shí)間的數(shù)學(xué)關(guān)系,從而得知生產(chǎn)線可靠性不僅與引起設(shè)備故障的各種直接因素有關(guān),還與維修水平、各緩存區(qū)實(shí)際緩存量、瓶頸單元的生產(chǎn)率以及故障設(shè)備在生產(chǎn)線的位置等因素有關(guān),為實(shí)際生產(chǎn)提供了理論參考。
[Abstract]:Taking buffer inventory and reliability of series repairable production line as research object, a series repairable production line structure model with exponential distribution of equipment failure rate and logarithmic normal distribution of service time is established based on production synergy. According to the different requirements of the reliability of the production line, the minimum buffer inventory, the calculation formula of the maximum cache and the equilibrium condition of the inventory are proposed with the different confidence upper limit of the average repair time as the repair time. An example is given to verify the validity of the formula. The mathematical relationship between the reliability of the production line and the maintenance time of the equipment is deduced, and the reliability of the production line is not only related to the direct factors causing the equipment failure, but also to the maintenance level and the actual cache quantity in each buffer area. The productivity of the bottleneck unit and the location of the fault equipment in the production line are related, which provides a theoretical reference for the actual production.
