Abstract
Provided is an analysis apparatus, including a work cost calculation unit configured to calculate a change in a work cost of a target plant when at least some target work, among work of an operator required to operate the target plant, is automatized. The analysis apparatus may include an automation cost calculation unit configured to calculate an automation cost for automatizing the target work; and a cost comparison unit configured to compare the work cost to the automation cost.
Claims13
An analysis apparatus, comprising
- at least one processor;
- a worklist generation unit, in the at least one processor, configured to detect those work operations by an operator that affect each other, and which converts contents of the work operations by the operator that affect each other into a worklist such that the work operations by the operator that affect each other are included in a single piece of work;
- a work independence determination unit, in the at least one processor, configured to determine an independence of each of the work operations by the operator that affect each other in the worklist;
- a work cost calculation unit, in the at least one processor, configured to calculate a change in a work cost of a target plant including a device and a pipeline when at least some target work, among the work operations of the operator required to operate the target plant including the device and the pipeline, is automated;
- an automation cost calculation unit, in the at least one processor, configured to calculate an automation cost for automating the at least some target work;
- and
- a cost comparison unit, in the at least one processor, configured to compare the work cost with the automation cost when the target plant is operated for a predetermined period after the automating,
- whereby the at least some target work is automated when a decrease in the work cost is greater than the automation cost.
