You can use time series methods but it will not be the same, because you will be approximating a complex model with a much simpler one.

You could always try neural networks, provided you have sufficient data to train one.

Probably the simplest way is to build a multiple regression model with a good "fit", that is one whose residuals are normally distributed with constant variance over the range of the dependent variable. Hopefully you would not have to do any data transformations to get a good fit.

Look in any basic statistics text under "Multiple Regression".
