Abstract

An apparatus or system is used for planning the rotation of part usage between shafts or plants based at least on schedule information relating to operation and inspection-purpose shutdown, attribute information relating to part life, part maintenance periods, and other part attributes, and part information relating to the parts to be used in the rotation.

Claims

1. A rotation planning apparatus comprising:

an operation schedule input means for accepting schedule information relating to equipment operation and shutdown for inspection of a plurality of shafts, and transmitting corresponding information,

a part type/attribute input means for accepting attribute information relating to lives, maintenance periods required, and other attributes of a plurality of parts, and transmitting corresponding information,

a part information input means for accepting part information relating to the plurality of parts as well as to replacement parts to be used in rotation with at least some of the plurality of parts, and transmitting corresponding information,

a part allocation processing means for receiving the corresponding information transmitted by said operation schedule input means, said part type/attribute input means, and said part information input means, allocating appropriate parts based on the corresponding information received, and outputting part allocation information,

an allocation establishment judging means for receiving said part allocation information, judging whether the appropriate parts can be put into operation during allocated operating periods, and outputting allocation establishment information, including an allocation of the plurality of parts and the replacement parts to the shafts, and

a display means for receiving the allocation establishment information and displaying the allocation establishment information, a total operation time of each of the plurality of parts, and a maintenance schedule for each of the plurality of parts for implementing a rotation plan.

2. The rotation planning apparatus as set forth in claim 1, further comprising an evaluation function calculating means for performing data calculations on established rotation plans, calculating evaluation values for said established rotation plans, and outputting the evaluation values to the plan display means.

3. The rotation planning apparatus as set forth in claim 1, further comprising monitoring information input means for receiving operation information from sensors on said shafts and outputting monitored information.

4. The rotation planning apparatus as set forth in claim 3, further comprising operation condition setting means for setting operating conditions and outputting operating condition set information.

5. The rotation planning apparatus as set forth in claim 4, further comprising life calculation means for receiving the monitored information and the operating condition set information, calculating part damage levels, calculating reductions in part service lives, determining part service life reduction information, and outputting the part service life reduction information to the part allocation processing means and the allocation establishment judging means.

6. A rotation planning system comprising a plurality of rotation planning apparatuses connected through a telecommunications line, at least one of said rotation planning apparatuses comprising:

an operation schedule input means for accepting schedule information relating to equipment operation and shutdown for inspection of a plurality of shafts, and transmitting corresponding information,

a part type/attribute input means for accepting attribute information relating to lives, maintenance periods required, and other attributes of a plurality of parts, and transmitting corresponding information,

a part information input means for accepting part information relating to the plurality of parts as well as to replacement parts to be used in rotation with at least some of the plurality of parts, and transmitting corresponding information,

a part allocation processing means for receiving the corresponding information transmitted by said operation schedule input means, said part type/attribute input means, and said part information input means, allocating appropriate parts based on the corresponding information received, and outputting part allocation information,

an allocation establishment judging means for receiving said part allocation information, judging whether the appropriate parts can be put into operation during allocated operating periods, and outputting allocation establishment information, including an allocation of the plurality of parts and the replacement parts to the shafts, and

a display means for receiving the allocation establishment information and displaying the allocation establishment information, a total operation time of each of the plurality of parts, and a maintenance schedule for each of the plurality of parts for implementing a rotation plan.

7. The rotation planning system as set forth in claim 6, wherein the at least one of said rotation planning apparatuses further comprises an evaluation function calculating means for performing data calculations on established rotation plans, calculating evaluation values for said established rotation plans, and outputting the evaluation values to the plan display means.

8. The rotation planning system as set forth in claim 6, wherein the at least one of said rotation planning apparatuses further comprises monitoring information input means for receiving operation information from sensors on said shafts and outputting monitored information.

9. The rotation planning system as set forth in claim 8, wherein the at least one of said rotation planning apparatuses further comprises operation condition setting means for setting operating conditions and outputting operating condition set information.

10. The rotation planning system as set forth in claim 9, wherein the at least one of said rotation planning apparatuses further comprises life calculation means for receiving the monitored information and the operating condition set information, calculating part damage levels, calculating reductions in part service lives, determining part service life reduction information, and outputting the part service life reduction information to the part allocation processing means and the allocation establishment judging means.
