human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "robust scheduling to minimize the weighted number of late jobs with interval due date uncertainty"):
  Abstract: We consider the class of single machine scheduling problems with the objective to minimize the weighted number of late jobs, under the assumption that completion due-dates are not known precisely at the time when decision-maker must provide a schedule. It is assumed that only the intervals to which the due-dates belong are known. The concept of maximum regret is used to define robust solution. A polynomial time algorithm is given for the case when weights of jobs are all equal. A mixed-integer linear programming formulation is provided for the general case, and computational experiments are reported.

Includes members:
  Member "min max regret scheduling to minimize the total weight of late jobs with interval uncertainty":
    also connected through other hyperedges:
      (none)
  Member "complexity of interval minmax regret scheduling on parallel identical machines with total completion time criterion":
    also connected through other hyperedges:
