Choosing among seven BASES

In this paper, the selection of a BASE Case was every bit as important as the simulation itself. The production team had been familiar with simulations and had used their results on previous projects. The team was concerned with the design of additional capacity for a current production line along with their ability to gain approval for the proposed project. They knew that simulation could be the basis for their decisions. But first they had to ask the right questions. This production line, at a major food manufacturer, had been simulated and reviewed. Since the original simulation, it was noted that the Cartoner speed and overall efficiency had been stated at too high a level. New simulations were required to support the project. While 88% efficiency had been used in the prior simulation, the historical efficiency was only at 60%. But that level of productivity would be considered unacceptable as a BASE to request the purchase of additional equipment.
