  1. Aggregate planning
    1. A firm plan its manufacturing activities
      1. Vatiety of levels
        1. Operate it as a system
        2. Covers a time between 3 to 18 months
          1. Goal
            1. Achieve a production plan
              1. Effectively utlize resources to satisfy expected demand
            2. Good resource input mix
              1. Influence

                      1. Time horizon=12 months
                        1. Level product demand=one or a few categories
                          1. Demand=fluctuating,seasonal or uncertain
