Abstract

This method, Maintenance Aid In Design, (MAID) generates the preliminary Maintenance Analysis Procedure (MAP) for systems in consideration, from the specified inputs. Inputs to the MAID contains four groups of information: (1) defined aid definition; (2) defined failure definitions; (3) relations between aids and failures; and (4) program options. This information is sorted to different tables and interpreted to MAP. Fig. 1 shows the general program flow.

Method for Generating Maintenance Analysis Procedures

This method, Maintenance Aid In Design, (MAID) generates the preliminary Maintenance Analysis Procedure (MAP) for systems in consideration, from the specified inputs. Inputs to the MAID contains four groups of information: (1) defined aid definition; (2) defined failure definitions; (3) relations between aids and failures; and (4) program options. This information is sorted to different tables and interpreted to MAP. Fig. 1 shows the general program flow.

See Fig. 1, subroutine FILL interprets inputs and fills Table 1 aid definitions; Table 2, failure definitions; Table 3, aid or failure remarks; Table 4, the hierarchies for the MAP; and Table 5, the aid-failure relation as shown. Subroutine SORT sorts the Table 5 according to the ascending order of recorded bits format and the specified hierarchies. This ascending order sorting guarantees that the records appearing later in the Table 5 should have at least the same or more aids applied (used) than the early appearing records. Subroutine EVAL then groups the identical records with the same usage of aids and fills the Table 6 as shown. The group indices in Table 6 shows the starting position of the identical group records (record contents is in the first part of the Table 6) in the sorted Table 5.

EVAL also prints out the grouped failures with associated aids and the conflicting usage of aids between failures. EVAL uses Table 2 and 3 to relate the symbolic name...
