How to create and use transfer function for multi input multi output systems

I have a system of dryer machine, the system has multiple inputs that are time dependent. At the end of the process, i get multiple outputs. For example ;

Inputs : Fan time, Heater time, condenser valve time, mass of laundries etc.

Outputs : Initial moisture value, final moisture value.

I have 4 different systems with 10 experiments of each. That means i have all the inputs and outputs for every experiment. To prevent try and fail for further experiments, i want to create a transfer function. But i don't know how. I will be pleased if somebody can help me.

@Osman Mert,

I do not understand what kind of transfer funciton you want to create. Is a transfer function (as you intend the term) (A) a complex function of frequency, or (B) a linear equation with four independent variables, or something else. The answer will depend on whether the inputs and outputs are truly time dependent. Please provide plots showing how the variables change with time.

I am not sure what values are time-dependent and what values are not. I am surprised that you say fan time and heater time are time-dependent. Please provide a plot of heater time versus time. Is final moisture value time-depndent? I doubt it. I am surprised that initial moisture value is an output. I would expect initial moisture to be an input, in a dryer experiment.
