Abstract

An object of the present invention is to provide the apparatuses and systems for planning the rotation of part usage between a plurality of shafts or plants.

The rotation planning apparatuses and system each comprise: a schedule information input section 1 for entering the schedule information relating to the operation and inspection-purpose shutdown of the plurality of shafts or plants for which operation plans are to be established; a part type/attribute input section 2 for entering the life, maintenance period requirements, maintenance cost requirements, and other attributes of each part that are predetermined according to the particular type of part; a part information input section 3 for entering the initial status of the parts whose usage is to be rotated, such as the operational status of these parts during the start of rotation planning, and the operation time of the parts; a part allocation processing section 4 by which either of the parts whose attributes have been entered is to be allocated to the entered operating periods between the inspection-purpose shutdown periods of the plurality of shafts or plants; an allocation establishment judging section 5 for judging the presence/absence of discrepancies in the operation plan after part allocation, and; a display plan section 6 for displaying the part allocation information, part-by-part total operating time, part replacement or repair timing covered in the established operation plan.

Claims

1. A rotation planning apparatus comprising;

an operation schedule input means for accepting the input of an operation schedule relating to at least either of a plurality of shafts or plants,

a part type/attribute input means for accepting the input of information relating to at least either the types or attributes of parts,

a part information input means for accepting the input of part information,

a part allocation processing means for allocating parts to an operation schedule relating to at least either of said plurality of shafts or plants, in accordance with the outputs of said operation schedule input means, said part type/attribute input means, and said part information input means, and

an allocation establishment judging means for judging the establishment of said allocation process from the output of said part allocation processing means.

2. Such a rotation planning apparatus as set forth in claim 1 above, wherein the rotation planning apparatus is characterized in that it further has a splitting rule input means for entering said part allocation rules into said part allocation processing means.

3. Such a rotation planning apparatus as set forth in claim 1 above, wherein the rotation planning apparatus is characterized in that said part allocation processing means also performs the allocation process based on the outputs of said allocation establishment judging means and said evaluation function calculating means.

4. Such a rotation planning apparatus as set forth in claim 1 above, further comprising;

an evaluation function calculating means for conducting evaluation calculations based on at least the outputs of said part allocation processing means and said allocation establishment judging means.

5. Such a rotation planning apparatus as set forth in claim 4 above, wherein the rotation planning apparatus is characterized in that it further has a splitting rule input means for entering said part allocation rules into said part allocation processing means.

6. Such a rotation planning apparatus as set forth in claim 4 above, wherein the rotation planning apparatus is characterized in that when evaluations and calculations are conducted by said evaluation function calculating means in accordance with the outputs of said part allocation processing means and said allocation establishment judging means, the sum of the residual lives of parts is used as an evaluation function.

7. Such a rotation planning apparatus as set forth in claim 4 above, wherein the rotation planning apparatus is characterized in that at said part allocation processing means, parts smaller in part number are allocated in normal ascending order of the starting date of the operating period of either of the plurality of shafts or plants, and in that part allocation to one operating period and the judgment relating to the establishment of the allocation are continuously conducted to determine the allocation of parts in normal ascending order of the starting date of the operating period.

8. Such a rotation planning apparatus as set forth in claim 4 above, wherein the rotation planning apparatus is characterized in that a plurality of operation plans relating to all operating periods for which the allocation establishment judgment has been established are set up and in that evaluation data on each operation plan is calculated by the evaluation function calculating means.

9. A rotation planning apparatus comprising;

an operation schedule input means for accepting the input of an operation schedule relating to at least either of a plurality of shafts or plants,

a part type/attribute input means for accepting the input of information relating to at least either the types or attributes of parts,

a part information input means for accepting the input of part information,

a part allocation processing means for allocating parts to an operation schedule relating to at least either of said plurality of shafts or plants, in accordance with the outputs of said operation schedule input means, said part type/attribute input means, and said part information input means,

an operating conditions setting means by which, when rotation is planned, operating conditions are set in accordance with the outputs of said part allocation processing means,

a monitoring information input means for entering the operating information obtained from the objects of rotation planning,

a life calculation means for calculating the lives of parts in accordance with the outputs of said monitoring information input means and said operating conditions setting means, and

an allocation establishment judging means for judging the establishment of said allocation process from the outputs of said operating conditions setting means and said life calculation means.

10. Such a rotation planning apparatus as set forth in claim 9 above, wherein the rotation planning apparatus is characterized in that said part allocation processing means also performs the allocation process based on the outputs of said life calculation means and said allocation establishment judging means.

11. A rotation planning system comprising a plurality of rotation planning apparatuses connected through a telecommunications line, wherein said rotation planning apparatuses comprising;

an operation schedule input means for accepting the input of an operation schedule relating to at least either of a plurality of shafts or plants,

a part type/attribute input means for accepting the input of information relating to at least either the types or attributes of parts,

a part information input means for accepting the input of part information,

a part allocation processing means for allocating parts to an operation schedule relating to at least either of said plurality of shafts or plants, in accordance with the outputs of said operation schedule input means, said part type/attribute input means, and said part information input means, and

an allocation establishment judging means for judging the establishment of said allocation process from the output of said part allocation processing means.
