Maintenance information management system and method of providing a maintenance plan

Abstract

In a maintenance management system and a method of providing support, maintenance information concerning generating plants owned by a user is provided to a maker, and the maker analyzes such items of information, and manages the information in a structure maintenance management system. The user accesses the maintenance management system through the Internet, extracts information to be obtained from databases, and implements maintenance activities or drafts a plan. Engineers of the maker register maintenance information through an intranet, and provide engineering support for the maintenance activities promoted by the user.

         3 . The maintenance information management system according to  claim 1 , wherein information on similar maintenance work carried out in the past concerning the major parts requiring maintenance work, on the basis of past maintenance information stored in said history management database, is stored in said planning management database.  
     
     
         4 . A maintenance information management system comprising: 
 a parts management database for storing information on parts making up a facility subject to maintenance owned by a user;    a history management database for storing a history of inspection or replacement of the parts concerning said parts management database; and    a planning management database for storing a maintenance plan concerning the parts, the maintenance plan being made on the basis of estimation of a situation of aged deterioration in the future concerning the parts on the basis of data stored in said parts management database and said history management database.    
     
     
         5 . The maintenance information management system according to  claim 4 , wherein a list of work items concerning major parts requiring maintenance activities as a future maintenance plan is stored in said planning management database.  
     
     
         6 . A maintenance information management system comprising: 
 a parts management database for storing parts information on major parts making up a facility subject to maintenance owned by a user;    a records management database for storing maintenance records concerning the facility subject to maintenance;    a history management database for storing a history of inspection or replacement of the major parts on the basis of the maintenance records stored in said records management database; and    a planning management database for storing a maintenance plan concerning the parts, the maintenance plan being made on the basis of estimation of a situation of aged deterioration in the future concerning the parts on the basis of data stored in said parts management database and said history management database.    
     
     
         7 . A method of providing a maintenance plan concerning major parts making up a facility subject to maintenance owned by a user, comprising the steps of: 
 storing in a parts management database parts information concerning the major parts making up the facility subject to maintenance owned by the user;    storing in a history management database a history of inspection or replacement of the major parts concerning said parts management database; and    estimating a situation of aged deterioration in the future concerning the major parts on the basis of data stored in said parts management database and said history management database, and providing a future maintenance plan concerning the major parts to the user on the basis of the estimation of the aged deterioration.    
     
     
         8 . The method of providing a maintenance plan according to  claim 7 , wherein warehousing/delivery information concerning parts information stored in said parts management database or history information on the inspection or replacement of the major parts stored in said history management database is registered by a service provider for providing maintenance service concerning the facility subject to maintenance owned by the user or by the user.  
     
     
         9 . The method of providing a maintenance plan according to  claim 7 , wherein information on similar maintenance work carried out in the past concerning the major parts requiring maintenance work, on the basis of past maintenance information stored in said history management database, is provided to the user.  
     
     
         10 . The method of providing a maintenance plan according to  claim 7 , wherein a list of work items concerning the major parts requiring maintenance activities as a future maintenance plan is provided.  
     
     
         11 . A method of providing a maintenance plan concerning parts making up a facility subject to maintenance owned by a user, comprising the steps of: 
 storing in a parts management database parts information concerning the parts making up the facility subject to maintenance owned by the user;    storing in a history management database a history of inspection or replacement of the parts concerning said parts management database; and    estimating a situation of aged deterioration in the future concerning the parts on the basis of data stored in said parts management database and said history management database, and providing a future maintenance plan concerning the parts to the user on the basis of the estimation of the aged deterioration.    
     
     
         12 . A method of providing a maintenance plan concerning major parts making up a facility subject to maintenance owned by a user, comprising the steps of: 
 storing in a parts management database parts information concerning the major parts making up the facility subject to maintenance owned by the user;    storing in a records management database maintenance records concerning the facility subject to maintenance;    storing in a history management database a history of inspection or replacement of the major parts stored in the records management database; and    estimating a situation of aged deterioration in the future concerning the major parts on the basis of data stored in said parts management database and said history management database, and providing a future maintenance plan concerning the major parts to the user on the basis of the estimation of the aged deterioration.    
     
     
         13 . A maintenance information management system comprising:
