Component exchange procedure identifying method and program

A computer-readable storage medium storing a program for causing a computer to execute a process for determining a procedure to exchange a component of an apparatus, said process comprising:

• storing data concerning a first component corresponding to an error code output from said apparatus into a storage unit;
• receiving failure data of a first operation verification of said apparatus, wherein said first operation verification was carried out after exchange of said first component and an assembling work of disassembled components;
• storing data concerning a second component corresponding to said error code into said storage unit;
• retrieving, from a component data storage storing data of components, and disassembling steps of each said component and assembling steps of each said component, a first disassembling procedure of said first component, wherein said first disassembling procedure comprises steps from a disassembling step that is a reverse step of an assembling step carried out immediately before said first operation verification to a disassembling step of said first component;
• retrieving from said component data storage, a second disassembling procedure of said second component, wherein said second disassembling procedure comprises steps from a primary disassembling step to be carried out when any component of said apparatus is exchanged to a disassembling step of said second component;
• storing said first and second disassembling procedures into a procedure storage;
• determining whether or not said first disassembling procedure is included in said second disassembling procedure;
• after determining that said first disassembling procedure is included in said second disassembling procedure, extracting, from said procedure storage, said disassembling step that is said reverse step of said assembling step carried out immediately before said first operation verification and subsequent disassembling steps among said second disassembling procedure, and storing the extracted disassembling steps into an output data storage;
• and
• outputting procedure explanation data corresponding to the steps stored in said output data storage.

A maintenance apparatus for determining a procedure to exchange a component of an apparatus, comprising:

• a storage unit;
• a procedure storage;
• a component data storage;
• an output data storage;
• a first unit that stores data concerning a first component corresponding to an error code output from said apparatus into said storage unit;
• a second unit that receives failure data of a first operation verification of said apparatus, wherein said first operation verification was carried out after exchange of said first component and an assembling work of disassembled components;
• a third unit that stores data concerning a second component corresponding to said error code into said storage unit;
• a fourth unit that retrieves, from said component data storage storing data of components, and disassembling steps of each said component and assembling steps of each said component, a first disassembling procedure of said first component, wherein said first disassembling procedure comprises steps from a disassembling step that is a reverse step of an assembling step carried out immediately before said first operation verification to a disassembling step of said first component;
• a fifth unit that retrieves from said component data storage, a second disassembling procedure of said second component, wherein said second disassembling procedure comprises steps from a primary disassembling step to be carried out when any component of said apparatus is exchanged to a disassembling step of said second component;
• a sixth unit that stores said first and second procedures into said procedure storage;
• a seventh unit that determines whether or not said first disassembling procedure is included in said second disassembling procedure;
• an eighth unit that extracts from said procedure storage, said disassembling step that is said reverse step of said assembling step carried out immediately before said first operation verification and subsequent disassembling steps among said second disassembling procedure after determining that said first disassembling procedure is included in said second disassembling procedure, and stores the extracted disassembling steps into said output data;
• and
• a ninth unit that outputs procedure explanation data corresponding to the steps stored in said output data storage.

A computer implemented method, comprising:

• the computer executing operations including:
• receiving an error code indicating a failure of assembly of components as a result of verification;
• determining whether a reassembly procedure of a first of the components includes a procedure of a second of the components based on whether the procedure of the second of the components includes a primary procedure necessary when any of the components is disassembled;
• extracting information defining procedures for assembling the first and second components by identifying each operation need for the reassembly;
• and
• displaying the extracted information, where the reassembly procedure of the first of the components includes a disassembling operation that is a reverse of an assembling operation carried out immediately before the verification.
