Abstract: A method of controlling a pressure swing adsorption unit in which a manipulated variable such as a capacity factor used by such unit in setting the bed cycle time is updated with a manipulated variable computed within a controller. The controller has a feed forward level of control in which the updated manipulated variable is calculated from a probability function when the product is likely to go off spec as determined by the probability function. In such manner, an optimal manipulated variable can be calculated that will maximize recovery in a manner that the probability of the product going off spec will be acceptable. If a specific impurity within the product is above a targeted range, a change to the optimal manipulated variable is computed with the use of a feedback level of control utilizing fuzzy logic.

Abstract: A vehicle transportation system, comprising the gathering of information consisting of vehicle availability and vehicle destination from a vehicle supplier interested in transporting vehicles from a first location to a second location and storing the vehicle availability information and said vehicle destination information into a centralized computer. An integrated framework programmed to match a vehicle with travelers and passengers to drive or be transported by the vehicle from the first location to the second location and making the vehicle availability information and vehicle destination information accessible via web page on the internet. A “supply chain” model to optimize the distance traveled, the number of vehicle and driver/traveler change overs and the time spent in between change overs and centralized auto terminals to allow for vehicle and driver exchanges.
