Description

Bidirectional collaborative linkage method for process version and maintenance procedure and related device Technical Field The application relates to the technical field of intelligent manufacturing, in particular to a bidirectional collaborative linkage method of a process version and a maintenance procedure and a related device. Background Currently, in manufacturing industries with extremely high requirements on process stability and production compliance, such as medicine and chemical industry, the problem of process version iteration update and equipment maintenance procedure adaptation and disconnection is particularly remarkable, and the requirements of full-link synergy are difficult to meet, and the method is specifically expressed as follows: (1) The process and maintenance management is split, the adaptive response is lagged, the problem of isolation of process management and maintenance management data is commonly existed at present, and a dynamic bidirectional association mechanism of process version and maintenance procedure is not established. For example, the invention patent application with chinese patent publication No. CN117455462a discloses a repair project informatization management system based on repair process structured data, which can only implement structured configuration, automatic production and resource statistics of a repair process, and does not establish a correlation map with a process version, and cannot respond to a change of repair requirements caused by update of the process version. For another example, although the design, process and simulation cooperation of the beauty engine CAPP (independently developed computer aided process design software for the number of beauty Yun Zhi) is realized, the beauty engine CAPP focuses on the product development stage, does not cover the linkage scheduling of equipment maintenance procedures in the production process, and needs to manually re-comb the maintenance procedures after the process version is changed, so that the response time is longer than 30 minutes, and the maintenance procedures are adapted and disjointed with the current production process, thereby seriously affecting the production efficiency. (2) The maintenance priority evaluation is on one side, the resource allocation is unbalanced, the existing maintenance priority evaluation method has obvious limitation, and a multi-dimensional quantitative weighting evaluation model is not formed. For example, the qualitative assessment method described in ICHEME related literature is only based on a single-dimensional quantification mode of equipment fault degree, core data such as process criticality, production task delivery urgency, resource matching degree and the like are not combined, so that high-priority maintenance requirements are omitted, low-priority requirements occupy a large amount of resources, and resource mismatch rate is high. (3) The maintenance procedure adjustment has no verification link and the trial-and-error cost is high, and the prior art lacks an effective front simulation verification closed loop after the maintenance procedure adjustment. For example, the above patent application relates to only inspection data collection after maintenance, and no adjusted suitability verification link is provided. For another example, the virtual simulation technology mentioned in Shanxi daily report related report is mostly applied to product design or production flow optimization, is not specifically used for the adaptation verification after the maintenance procedure adjustment, and causes the problem that the maintenance procedure is easy to be mismatched with equipment and technology, the secondary maintenance rate exceeds 40%, and the trial-and-error cost is extremely high. (4) The existing system does not form a full-flow traceable log system for process version change and maintenance procedure adjustment, cannot meet the requirement of compliance standards such as GMP, ISO9001 and the like in the pharmaceutical industry and the chemical industry on the traceability of the production process, and lacks complete records of key data such as information before and after process change, maintenance adjustment details, operation main bodies, verification results and the like, so that compliance risks exist, and the industry suitability is limited. In summary, the prior art fails to open up the data flow and the service flow from the process design to the maintenance execution, and has systematic defects in dynamic linkage, intelligent decision, simulation verification and compliance tracing. Therefore, an innovative scheme capable of realizing intelligent, bidirectional and closed-loop coordination of process version and maintenance procedure is needed to improve the overall adaptability, resource efficiency and compliance level of the production system.
