Abstract:
|
Spare parts are critical to operational readiness. Their availability depends on logisticians' choices for reorder points and order quantities. Simulation allows planners to calculate these control variables without making unwarranted assumptions (e.g., demand is Poisson). Imagine a simulation of a spare parts inventory system that requires daily part demand data as an input. If you only have demand history bucketed monthly, how do you proceed? Converting monthly data to daily data is an example of the time series disaggregation problem. We discuss current (inadequate) solutions to this problem and present a (less inadequate) solution that suffices for some instances of interest.
