Nobody here can tell you what the demand is. You have to figure that
out for yourself. Fit a probability distribution to historic data.
There is software that will do that for you. Validate all
distributions with with line managers who know the business BTW. You
can start the system with inventories set at an average level, but
you'll want to "Warm Up" the system to stability before you start
collecting data.
