Abstract
A method of production planning includes steps of: (a) collecting sample data points for a resource type, each of the sample data points representing an individual relationship among arrival workload, initial work-in-process (WIP) workload and input workload of the resource type; and (b) establishing a capacity model that models the relationship among arrival workload, initial WIP workload and expected input workload of the resource type according to the sample data points collected in step (a), a first predetermined objective function, and a first set of predetermined constraints.
