________ forecasting methods use historical demand to make a forecast.

A) Qualitative
B) Time-series
C) Causal
D) Simulation

Time-series forecasting methods use historical demand data to identify patterns and trends in the data that can be used to make a forecast. These methods include techniques such as moving averages, exponential smoothing, and trend analysis. Qualitative methods rely on expert opinions, and causal methods focus on understanding the underlying factors that drive demand. Simulation methods use mathematical models to simulate demand under different scenarios.
