Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to generate a workscope. An example apparatus includes a workscope mapper, workscope strategy analyzer, and workscope selector. The workscope strategy analyzer is to evaluate each of the plurality of workscopes using dynamic optimization to determine a maintenance value and benefit to an asset associated with each workscope based on a stage in a remaining life of a constraint at which the evaluation is executed and a state of the asset. The dynamic optimization is to determine a prediction of the maintenance value based on a probability of a future change in state and associated workscope value until the end of life of the constraint. The maintenance value, used to select a workscope from the plurality of workscopes, is to be determined by the dynamic optimization as a sum of the associated workscope values until the end of life of the constraint.

Abstract: Some embodiments facilitate creation of an industrial asset item via a rotary additive manufacturing process. For example, a build plate may rotate about a vertical axis and move, relative to a print arm, along the vertical axis during printing. An industrial asset item definition data store may contain at least one electronic record defining the industrial asset item. A frame creation computer processor may slice the data defining the industrial asset item to create a series of two-dimensional, locally linear frames helically arranged as a spiral staircase of steps (and each step may be oriented normal to the vertical axis. Indications of the series of two-dimensional frames may then be output to be provided to a rotary three-dimensional printer.
