Abstract: A method for processing workpieces in a process flow including a plurality of operations includes employing a fabrication simulation model of the process flow to determine an estimated completion time for a selected workpiece. The fabrication simulation model simulates the processing of the selected workpiece and other workpieces in the process flow through the plurality of operations. The priority of the selected workpiece is adjusted based on a comparison between a target completion time for the selected workpiece and the estimated completion time.

Abstract: A method for scheduling preventative maintenance tasks includes defining a set of global time periods. Members of a set of preventative maintenance tasks associated with a plurality of machines for are scheduled execution during the global time periods based on capacities of the machines and production targets for the machines. A plurality of time slots is defined for a selected global period having a selected preventative maintenance task scheduled for execution therein. A selected time slot from the plurality of time slots is scheduled for performing the selected preventative maintenance task based on work in process levels for with the associated machine over the time slots.

Abstract: A method includes identifying a queue of workpiece lots awaiting processing in a process tool. At least one of the workpiece lots is associated with an obsolete control thread for controlling the process tool. Each of the plurality of workpiece lots is modeled as a parent lot and a child lot. A completion time for the workpiece lots is optimized by selecting a processing order of the workpiece lots and designating one of the child lots associated with the obsolete control thread as a pilot lot. A first workpiece lot in the selected processing order is processed in the process tool.

Abstract: A method for determining metrology sampling rates for workpieces in a process flow includes determining a current status of the process flow. Future processing of the workpieces in the process flow is simulated based on the current status of the process flow over a predetermined time horizon to predict sampling rates for the workpieces. During the simulating, sampling rules are implemented that consider capacity constraints of a metrology resource in the process flow. Actual workpieces in the process flow are sampled based on the predicted metrology sampling rates.

Abstract: The invention relates to a pharmaceutical composition and a method for treating drug addicts' withdrawal syndrome and detoxifying addicts. The pharmaceutical composition comprises aconitane derivative of formulas I, II, their inorganic acid salts or mixtures thereof, and tetrahydroprotoberberine derivatives of formula II. The method of treatment comprises administering the pharmaceutical composition to drug addicts. The pharmaceutical composition of the present invention produces no drug dependence, excellent effects, fast action and low side-effects.

Abstract: This invention relates to a medication to treat addicts who are addicted to drugs or narcotics (including opium, morphine, heroine, cocaine, marijuana, amphetamine, etc.), the preparative method of this medication, as well as the treatment method for the addicts by using this medication. This medication to treat addiction is aconitane deivative having structures of formula I or II, wherein the formula I, R=.alpha.--OCH.sub.3, .beta.--OCH.sub.3 or .alpha.--OH; R.sub.1 =OAcABz, OH, OABz or H; R.sub.2 =H or OH; R.sub.3 =H or OH; R.sub.4 =H or OH; R.sub.5 =H or OH; R.sub.6 =OCH.sub.3, OBz, OAc or OH; wherein the formula II, R.sub.1 =R.sub.2 =R.sub.3 =OH.This medication to treat addiction is characterized by no drug-dependence, high cure effect, fast action and low side effect.
