Over the life cycle of a part, it is possible for the user to evaluate the life cycle
when the user replaces it by connecting the life cycle of another part in the market
or a part used by another user to the stage of replacement or disposal.
20.4.2 Prediction and Assessment
A part agent expands the life cycle model by using the state of the part and a deterioration model. Figure 20.7 illustrates how a part agent selects the next stage using
the expanded life cycle of the part. The figure shows a situation where the current
stage is the use stage, and the next possible stages are Stage1, Stage1
, and Stage1
.
A circle denotes an expanded life cycle stage with its property value of profit, cost,
