Abstract
A plant maintenance control system designed to be effectuated through use of a computer; the basic aspect of the system relates to the unique results obtainable through particular operations performed by the computer based upon the unique organization and arrangement of the so-called data base complex, such that efficient and detailed control of maintenance expenses for a complicated chemical plant or the like can be readily established.
Claims18
A plant maintenance control method by which control over maintenance expenses is established through a computer data base system, said method comprising:
- providing a data base complex having at least four complete, non-redundant, individual data bases, each data base being composed of a plurality of data base records each of which is adapted to contain data in a hierarchical structure comprising a root segment and dependent or subordinate segments,
- establishing logical pointer relationships between at least said first data base and each of said other three data bases;
- routing data through said computer to and from said data base complex;
- accessing data from said individual data bases by searching segments selectively in each of the data bases based on a preordained selection method and in accordance with said established logical pointer relationships.
A plant maintenance control system in which control over expenses is established through a computer data base system, said system comprising:
- a computer;
- a data base complex having at least four individual data bases, each containing data in a hierarchical structure, each of said hierarchical structures comprising a root segment and dependent or subordinate segments;
- the first data base containing data with respect to maintenance requests for maintenance work to be performed on equipment in said plant;
- the second data base containing data with respect to the project to which the maintenance work is assigned;
- the third data base containing data with respect to the cost center responsible for particular maintenance requests;
- the fourth data base, submod, containing data as to functional groupings of equipment;
- a plurality of terminal devices for routing data through said computer to and from said data base complex;
- means for establishing logical pointer relationships between at least said first data base and each of said other three data bases respectively;
- means for accessing data from the individual data bases by searching said segments selectively in each of the data bases based on a preordained selection method in accordance with said established logical pointer relationships.
