    摘要: The present invention can include a method for handling the uncertainty of input variables in the calculation of the net present value (NPV) of a project that utilizes a Monte Carlo approach. Such a method can begin by expressing the equation for the net present value (NPV) in a probabilistic form. The probabilistic form can allow for the input variables to be treated as random variables with triangular distributions. Various equation parameters for the probabilistic NPV equation can be defined. A Monte Carlo computational algorithm can be executed that utilizes the probabilistic NPV equation and the defined equation parameters to produce multiple probabilistic NPV distributions. For each probabilistic NPV distribution, a mean value and a standard deviation can be ascertained. The mean value can represent the present value (PV) of the project and the standard deviation can represent the associated risk of the project.

    摘要: An apparatus and a method of encoding a dirty bit within plural bit control data for controlling an operation by a computer graphics system to simultaneously indicate reset or clear of data for a pixel in the system to quickly update a frame on a screen in an animation application are disclosed. Flexibility of the encoding dirty bits and a trade-off among a relative size of a set of control data available for the system to control the operation are easily achieved by the apparatus and the method.

    摘要: System, method and graphical user interface for a simulation base calculator provides one or more selectable distribution models. One or more input fields are provided for inputting rules with one or more random variables. A processing module inputs one or more of the selectable distribution models and the rules into a simulator running on the system. An output field is provided for displaying one or more aspects of a result determined by the model run on the simulator.
