CumulativeDecomposition

public CumulativeDecomposition(CPIntVar[] start,
 int[] duration,
 int[] demand,
 int capa)

Creates a cumulative constraint with a decomposition into sum constraint. At any time-point t, the sum of the demands of the activities overlapping t do not overlap the capacity.

Parameters:

start - the start time of each activities

duration - the duration of each activities (non negative)

demand - the demand of each activities, non negative

capa - the capacity of the constraint
