Suppose that Safeway has decided to install a new system to better compete with walmart. Their system will use RFID technology and suppose that it will allow a full basket of groceries to be scanned automatically without being removed from the cart, and the total tabulated in only a few seconds. Bagging will be simplified to take at most one minute for a whole cart. What system changes will be seen with this system? Check all that apply.

A. Decreased load factor (assuming demand stays the same) coming from increased capacity because processing time at checkout is greatly decreased.

B. Lower congestion in the checkout process because they have removed the manual process of scanning items, thus resulting in less variability.

C. An increase in utilization due to getting customers through the process faster which decreases capacity.

D. Increased congestion in the system resulting from the increased variability in bagging times.
