  3. The maintenance plan creation process according to Claim 1 , wherein, if the first assembly line is stopped, the downtime is calculated on the basis of the working time required to carry out maintenance work on the first assembly line.
  4. The maintenance plan creation process according to Claim 1 , wherein, based on the working time required for the work on one or more work objects included in the maintenance work to be carried out on the second assembly line, the maintenance work plan for the second assembly line is created in such a way that a work object which requires a longer working time among the one or more work objects is preferably assigned so that it is carried out before the second production process.
  5. The maintenance plan creation process according to Claim 4 , wherein, if a work object exists that requires working time that is less than or equal to the downtime, the maintenance work plan for the second assembly line is created such that the work object is assigned before the second production process, and if a work object that requires working time that is less than or equal to the downtime does not exist, the maintenance work plan for the second assembly line is created such that one or more processes from a plurality of processes contained in a work object under the one or more work objects are assigned to be carried out before the second production process, and the remaining processes from the plurality of processes are assigned to be carried out after the second production process.
  6. The maintenance plan creation process according to Claim 1 , furthermore encompassing: causing a display to show: (i) production plans that include production processes for the first assembly line and the second assembly line, and (ii) a preparatory work plan linked to the production plans; and: highlighting the following works (iii) and (iv) that are included in the preparatory work in conjunction with each other: (iii) the first preparatory work, which specifies the work of removing the work unit from the first assembly line after completion of the first production process, and (iv) the second preparatory work, which specifies the work of attaching the work unit removed from the first assembly line to the second assembly line.
  7. The maintenance plan creation process according to Claim 6 , which also causes the display to highlight the downtime.
  8. A maintenance plan creation device comprising: a receiver that receives information about a work unit attached to a first assembly line to which a first production process is assigned; a determiner that, based on the received information, determines the presence or absence of a second production process to be carried out after the work unit has been removed from the first assembly line and attached to a second assembly line following completion of the first production process; a computer that, if it is determined that the second production process is present, calculates the downtime of the second assembly line resulting from the waiting time until the completion of the first production process; and a creator that generates a maintenance work plan based on the calculated downtime.
  9. A program that causes one or more processors to execute the maintenance plan creation procedure according to any of the Claims 1 until 7 executes.
  10. A maintenance procedure comprising: obtaining information about a work unit attached to a first assembly line to which a first production process is assigned; determining, based on the information obtained, the presence or absence of a second production process to be carried out after the work unit has been removed from the first assembly line upon completion of the first production process and attached to a second assembly line; calculating, if the presence of the second production process is determined, the downtime of the second assembly line resulting from the waiting time until the completion of the first production process; and causing a maintenance worker to perform maintenance work to be carried out on the second assembly line during the calculated downtime of the second assembly line.

Description

[Technical field] The present invention relates to a maintenance plan creation method, a maintenance plan creation device, a program and a maintenance method. [Background technology] There are devices used to mount components onto substrates. To maintain the quality of these devices, maintenance processes, such as cleaning, are performed. Patent Literature (PTL) 1 discloses a device that notifies other devices that have previously completed their processes of the remaining working time required for processes to be performed on substrates supplied by upstream devices. The other devices that receive the notification compare the notified remaining working time with the time required to perform self-maintenance work, and if the self-maintenance work can be completed within the remaining working time, the self-maintenance work is carried out. As described, the other remaining devices that completed the processes earlier perform maintenance using a waiting time until the one device has completed the work, for example, if differences occur in the times at which the devices complete the processes due to an unexpected fault in one device. This allows the operating rate of an assembly line consisting of the above-mentioned devices to be increased while the necessary maintenance processes are carried out. [List of objections] [Patent literature] [PTL 1] Unexamined Japanese patent application, publication number 2009-081170 [Summary of the invention] [Technical problem] Even in a system that includes a large number of assembly lines, there is a need to maintain the quality of each assembly line while simultaneously reducing the degradation of the operating rate of each assembly line.
