If they are really unskilled, then they will probably forget to push the button while the machine's still open. So, an automatic solution should be choosen Yes, this is very true. which is referring to the closing of door. But that isn't. :-( As mentioned before, door activity is not a conclusive indication of filling activity! Vending machines record the number of products sold, but I have yet to see one that can tell how much stock it has. Some machines can't even tell whether they have any stock at all - they just have a sensor to determine whether a product is actually dispensed as a result of a vend attempt; if not, they refund the money. In fact, some machines - ones where you can actually see the stock - don't even do this. They just assume that the customer won't be so stupid as to select an obviously sold-out product! Or am I missing something? Yes - door opening is a Necessary condition for a refill, but not a Sufficient condition. |
