Abstract:
1. A plan execution control apparatus configured to give an instruction to maintain a plurality of installations connected to each other, wherein system linkage structural data is used to represent a connection structure of the plurality of the installations, and a target reliability is used to indicate a required probability value at which each of the installations is to be normally used through a wired connection path, the plan execution control apparatus comprising: a linkage reliability calculating section configured, for the each of the installations, to extract one or more wired connection paths to the installation based on the system linkage structural data, wherein power is distributed through the one or more wired connection paths, to define a linkage reliability indicating a probability value at which the installation can be normally used through any one of the extracted wired connection paths, using a wired connection path reliability indicating a probability value at which at least one of the extracted wired connection paths can be normally used and a soundness indicating a probability value at which the installation is not faulty, and to calculate a target soundness of each installations such that the linkage reliability of the installation satisfies a target reliability of the installation; a damaged state transition control section configured to provide a damaged state transition structure of the each of the installations; a maintenance time limit calculating section configured to calculate a time limit related to a maintenance work, based on the damaged state transition structure of the each of the installations provided by the damaged state transition control section and the target soundness required for the each of the installations and calculated by the linkage reliability calculating section; a constraint control section configured to recognize and record constraints related to traveling of maintenance personnel, a traveling workload, and a workload; and an itinerary maintenance determining section configured to calculate an itinerary schedule indicating an assignment to an object to be maintained among the installations, based on the maintenance time limit, the constraints, the traveling workload, and the workload.
