Embodiment Construction

[0059] The purpose of the present invention is to provide a MES equipment maintenance early warning method and system to improve the accuracy of equipment maintenance decision-making.

[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, the invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] Since the factors that affect the selection of maintenance methods are often multiple and fuzzy, the AHP is an effective decision-making method for qualitative and quantitative analysis. Combined with two layers of fuzzy comprehensive evaluation, a multi-level early warning maintenance method for MES equipment maintenance is finally constructed. The decision-making model aims to provide scientific basis for equipment maintenance and early warning decision-making.

[0062] The present invention provides an MES (Manufacturing Execution System, Manufac...

Abstract

The invention discloses an MES equipment maintenance early warning method and system, and the method comprises the following steps: constructing a multi-level MES equipment maintenance early warning decision analysis system which comprises a target layer, a criterion layer and a sub-criterion layer, The target layer comprises the grade of MES equipment maintenance early warning, the criterion layer comprises reliability and economy, and the sub-criterion layer comprises the residual service life, the fault frequency and the residual economic life of the equipment; calculating a value of each element of the sub-criterion layer of the equipment according to the measurement data; and determining the maintenance early warning level of the equipment by adopting an APH algorithm according to thevalue of each element of the sub-criterion layer. According to the invention, the multi-level MES equipment maintenance early warning decision analysis system including economy and reliability is established, the maintenance early warning level of the equipment is determined by adopting an AHP-based fuzzy comprehensive evaluation method, maintenance is carried out according to the decision schemecorresponding to the maintenance early warning level, and the accuracy of equipment maintenance decision is improved.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a method and system for early warning of MES equipment maintenance. Background technique [0002] MES is a set of production information management system oriented to the executive level of the workshop of manufacturing enterprises. Equipment maintenance management and inventory management are its important features. [0003] Equipment maintenance includes three parts: equipment inspection, preventive maintenance and predictive maintenance. During the equipment inspection process, the inspection data is sent back to the server in real time for storage, analysis, and alarm. Through the maintenance plan / rule, the on-site terminal is used to perform equipment maintenance, and the data is sent back in real time and the progress is tracked. [0004] Equipment maintenance under the Industrial Internet, from after-sales maintenance to preventive maintenance and then to su...
