Which of the following decision support tools is used to determine capacity requirements on the basis of future demand?

Decision trees are a graphical representation of decisions and their possible consequences, including chance event outcomes. They are primarily used for decision analysis, focusing on the potential impacts of various choices rather than predicting future demand or determining capacity requirements. Thus, they do not directly relate to capacity planning.

Capacity cushions refer to the extra capacity a company maintains to handle sudden increases in demand or unexpected disruptions. While relevant to capacity management, capacity cushions do not directly predict future demand. Instead, they are a strategy to manage variability once demand forecasts have been established.

Break-even analysis is a financial calculation to determine the point at which total revenues equal total costs. This tool helps in understanding profitability rather than forecasting future demand or determining capacity needs. Therefore, it is not suitable for assessing capacity requirements based on expected demand.
