  Hereinafter, an embodiment of a component selection device, a transition diagram drawing program, and a component selection method according to the present invention will be described with reference to the drawings.

[First Embodiment]
The first embodiment of the present invention will be described below.
FIG. 1 is a block diagram showing an electrical configuration of a component selection apparatus 10 according to the first embodiment. The component selection device 10 is a so-called information processing device, and displays a transition diagram in which components having a context of improvement are represented by nodes and links on a monitor 22 described later. The context of the improvement is a relationship between a part derived from the improvement (child part) and a part before the improvement (parent part), a so-called parent-child relation, each having different specifications. The user of the part selection device 10 selects a part that replaces the part to be replaced by checking the transition diagram.
The parts to be replaced are parts used in a plant including, for example, a gas turbine, and the maintenance time and the like of the parts are managed by a customer who is a plant delivery destination. Then, information on the part to be replaced is notified to the manufacturer of the part, and the part is selected by the manufacturer. That is, the part selection apparatus 10 is used by a manufacturer of parts that delivers parts to customers as an example.

The component selection apparatus 10 according to the first embodiment includes a CPU (Central Processing Unit) 12 that controls the operation of the entire component selection apparatus 10, a ROM (Read Only Memory) 14 in which various programs, various data, and the like are stored in advance, and a CPU 12 RAM (Random Access Memory) 16 used as a work area at the time of execution of various programs according to the above, and an HDD (Hard Disk Drive) 18 as storage means for storing various programs and various data.
Further, the component selection device 10 includes a keyboard, a mouse, and the like, and includes an input unit 20 that receives input of various operations, a monitor 22 such as a liquid crystal display device that displays various images, and other information processing via a communication line. An external interface 24 that is connected to a device or the like and transmits / receives various data to / from other information processing devices or the like is provided.

  The CPU 12, ROM 14, RAM 16, HDD 18, input unit 20, monitor 22, and external interface 24 are electrically connected to each other via a system bus 26. Therefore, the CPU 12 accesses the ROM 14, RAM 16, and HDD 18, grasps the operation state of the input unit 20, displays an image on the monitor 22, and transmits / receives various data to / from other information processing apparatuses via the external interface 24. Etc. can be performed respectively.

The HDD 18 stores a component database in which the order of improvement between components is described together with component information indicating the components. The parts database is generated for each type of parts (for example, moving blades and stationary blades in the case of gas turbine parts).
FIG. 2 is a schematic diagram showing the configuration of the component database 30. The component database 30 associates a component version, a recommended flag, a subsequent component, and a specification difference for each component code that is identification information indicating a component. The component version, recommended flag, subsequent component, and specification difference are collectively referred to as component information.

  The component version is information indicating a component change history.

  The recommended flag is a recommended part (hereinafter referred to as “recommended part”), and is arbitrarily set. In the parts database 30 according to the first embodiment, “1” is described as a recommended part as an example. Note that the latest version of components is not necessarily recommended. Even the latest version of a part may be a part dedicated to a particular customer, and such parts are less versatile and may not be recommended.

  The succeeding part is a part obtained by improving the part indicated by the part code, and the part version of the part is described. As described above, the improvement context between the parts is specified by the version information that is the change history of the parts, so that the improvement context of the parts can be easily grasped. When there are a plurality of subsequent parts, the part versions are described in the subsequent part 1, the subsequent part 2, the subsequent part 3, and the like.

  The specification difference is information indicating a difference in specifications between components in the context of improvement. As shown in the example of FIG. 2, “addition of coating” is described as a specification difference for a Ver1.1 part obtained by adding a coating to a Ver1.0 part. When there are a plurality of subsequent components, the specification differences are described in the component 1 specification difference, the component 2 specification difference, the component 3 specification difference, and the like corresponding to the subsequent components.

  The component database 30 shown in FIG. 2 is created in advance, and each piece of information is input by the user of the component selection device 10, for example.

  The input unit 20 is operated by a user of the component selection device 10 and functions as an input unit that receives an input of a component code. Note that the part to which the part code is input, that is, the selected part is, for example, a part to be replaced.

The CPU 12 reads the parts in the context of the improvement including the parts indicated by the part code input by the input unit 20 from the parts database 30 in a chain. That is, the parts derived from the improvement are read out from the parts database 30 in the following formula.
Then, as shown in FIG. 3, the CPU 12 draws the read component as a node 32, and at the same time, draws a transition diagram 36 in which a link 34 (line) that connects nodes 32 indicating components before and after improvement is drawn. Displayed on the monitor 22. The transition diagram 36 has a tree structure because the nodes 32 indicating the parts before and after the improvement are connected by the link 34. By visualizing the transition diagram 36 in a tree structure, the user of the component selection device 10 can easily grasp the component derived by the improvement.

  As described above, the user of the part selection device 10 can easily select a part to replace the part to be replaced by inputting the part code of the part to be replaced and displaying the transition diagram 36 on the monitor 22. .

  The transition diagram 36 shown in FIG. 3 is generated based on the parts database 30 shown in FIG.

  Although the component version is drawn as a label on the node 32, the present invention is not limited to this, and a component code may be drawn as a label. An image based on the specification difference described in the component database 30 is drawn on the link 34. Thereby, the user of the part selection apparatus 10 can grasp | ascertain the difference in the specification between components easily.

  Furthermore, a node 32 indicating a recommended part is highlighted as a replacement for the part to be replaced. The highlighted node 32 is a component whose recommended flag is “1”. Thereby, the user of the part selection apparatus 10 can grasp | ascertain easily the recommended part which can be proposed to a customer. The component selection apparatus 10 according to the first embodiment draws the node 32 with a double line as an example of highlighting, but is not limited to this, for example, a color change or a component version drawn as a label on the node 32 The font may be highlighted by changing the font.

  In addition, the component for which the component code is input via the input unit 20 is highlighted differently from the recommended component.

In the transition diagram 36, as shown by the area surrounded by the broken line in FIG. 3, the nodes 32 of compatible parts are connected by a straight link 34 or a branched link 34. The nodes 32 connected by the branched link 34 are, for example, a node 32 of “Ver1.0” and a node 32 of “Ver2.0”.
On the other hand, the nodes 32 indicating incompatible parts are not coupled by the link 34. For example, since the node 32 of “Ver1.2” and the node 32 of “Ver2.1” are not connected by the link 34, the parts indicated by these nodes 32 are not compatible. Also, the “Ver1.1” node 32 and the “Ver2.0” node 32 branched from the “Ver1.0” node 32 are not coupled by the link 34 and are not compatible.

  FIG. 4 is a flowchart showing a flow of processing (hereinafter referred to as “component selection processing”) performed by a person in charge in order to select a maintenance target component (hereinafter referred to as “target component”). The person in charge is also a user of the component selection device 10.

  First, in step 100, the person in charge determines whether or not the target part needs to be replaced. When the target part needs to be replaced, the process proceeds to step 102, and the target part does not need to be replaced. Shifts to Step 104.

  In step 102, since there is no need to replace the target part, the part selection process is terminated, and the target part is repaired or cleaned instead of replacing the part.

  In step 104, the person in charge inputs a part number indicating the target part to the part selection apparatus 10 via the input unit 20 of the part selection apparatus 10.

  In the next step 106, a transition diagram 36 including the target part is displayed on the monitor 22 of the part selection device 10.

  In the next step 108, the person in charge investigates the target part using the transition diagram 36.

  In the next step 110, as a result of the investigation, the person in charge determines whether or not a recommended part replacing the target part, that is, a recommended part compatible with the target part is displayed in the transition diagram 36. The process proceeds to step 112. If the determination is negative, the process proceeds to step 120.

  In step 112, the person in charge determines whether there are a plurality of recommended parts. If the determination is affirmative, the process proceeds to step 114. If the determination is negative, the process proceeds to step 118.

In step 114, the person in charge investigates the past purchase record of the customer. The purchase performance is the orientation (hereinafter referred to as “customer purchase orientation”) in selecting the past parts by the customer.
The customer purchase orientation is, for example, a performance orientation that desires increased output and high efficiency, a cost orientation that desires a low cost, and an identity orientation that desires the same part without changing the part.

  In step 116, the person in charge selects a recommended part to replace the target part by checking the specification difference drawn in the transition diagram 36 for the part corresponding to the purchase result of the customer, and the part selection process is terminated.

  In step 118, which shifts to a negative determination in step 112, since there is only one recommended component, the person in charge selects the recommended component as a component that replaces the target component, and the component selection process ends.

  In step 120, which shifts to the case where a negative determination is made in step 110, the person in charge selects a part based on the part manufacturing strategy. The manufacturing strategy is, for example, the presence / absence of a stock item, a sales policy, and the availability of continuous production of parts.

  In the next step 122, if the person in charge determines that the target part should be replaced with a newer version of the part (hereinafter referred to as “compatible part”), the process proceeds to step 124. . On the other hand, if the person in charge determines that the same part should be replaced, the process proceeds to step 126.

  In step 124, the person in charge selects a compatible part as a part that replaces the target part, and the part selection process ends.

  In step 126, the person in charge selects the same part as the target part, and the part selection process ends.

  FIG. 5 is a flowchart showing a flow of a transition diagram drawing process (transition diagram drawing program) executed by the CPU 12 of the component selection device 10 when the component selection device 10 draws the transition diagram 36. The transition diagram drawing program is stored in a predetermined area of the HDD 18 in advance. The transition diagram drawing process starts when a component code is input to the component selection device 10 via the input unit 20. That is, the transition diagram drawing process is step 106 in the part selection process.

  First, in step 200, the oldest part version, that is, the part information of “Ver1.0” is read from the part database 30 among the parts having the context of improvement including the input part code.

  In the next step 202, it is determined whether or not a recommendation flag is described in the read component information. If the determination is affirmative, the process proceeds to step 204. If the determination is negative, the process proceeds to step 206.

  In step 204, the node 32 corresponding to the read component information is drawn with a double line.

  In step 206, the node 32 corresponding to the read component information is drawn with a single line.

  In the next step 208, the component version is drawn as a label on the node 32.

  In the next step 210, it is determined whether or not a subsequent component is described in the read component information. If the determination is affirmative, the process proceeds to step 212. If the determination is negative, the process proceeds to step 218.

  In step 212, a link 34 for coupling with the node 32 of the subsequent part is drawn.

  In the next step 214, the specification difference is drawn.

  In the next step 216, the component information of the subsequent component is read and the process returns to step 202. By returning to step 202, the presence / absence of the recommendation flag of the subsequent component is determined and the node 32 of the subsequent component is drawn. After that, by further repeating the steps, parts in the context of improvement are read out from the parts database 30 in a chain.

  On the other hand, in step 218, which is shifted when a negative determination is made in step 210, it is determined whether or not the nodes 32 of all parts in the context of improvement have been drawn. If the determination is affirmative, a transition diagram drawing process is performed. When the determination is negative, the routine proceeds to step 220.

  In step 220, the component information in which the node 32 is not drawn is read, the process proceeds to step 202, and the above steps are repeated until the nodes 32 of all the components in the context of improvement are drawn.

As described above, the component selection apparatus 10 according to the first embodiment includes the HDD 18 that stores the component database 30 in which the component code corresponding to each of a plurality of components and the order of improvement between components are described. Then, the part selection device 10 receives the input of the part code indicating the part by the input unit 20, and the parts in the context of improvement including the part indicated by the input part code are chained from the part database 30. In addition, the read part is drawn as a node 32, and a transition diagram 36 in which a link 34 connecting the nodes 32 indicating parts before and after the improvement is drawn is displayed on the monitor 22.
Therefore, the component selection apparatus 10 according to the first embodiment visualizes the relationship between the components derived by the improvement, and enables easy selection of the components.
