Optimization and sensitivity analysis of computer simulation models by the score function method

Article Abstract:

The score function (SF) method is an appropriate technique for performance evaluation, sensitivity analysis and optimization of complex discrete-event static and dynamic systems such as computer-communication networks, flexible manufacturing systems, PERT-project networks and flow networks. The SF method enables the evaluation simultaneously from a single sample path of the performance and all its sensitivities of discrete-event systems. It also allows users to solve optimization problems.

A simulation model for emergency evacuation

Article Abstract:

A prototype spatial decision support system which is employed by emergency planners in developing contingency plans for evacuations from disaster areas was developed. The CEMPS prototype system interconnects a geographical information system (ARC/INFO) with an object-oriented micro-simulator through a widowing computer operating system. The simulator was written in C++, uses an existing library and adopts an object-oriented viewpoint with a class hierarchy.
