FOP SIM LENGTH This option specifies the time to run for each simulation iteration. No default is assumed, so the user has to specify a value for it whenever IOP SIMULATION is VAL YES. FOP SIM CONFIDENCE This option specifies the required confidence for the simulation, a number between zero and one. Currently, only 90%, 95%, or 99% can be specified. FOP SIM ERROR If IOP SIM RUNS is 0 or left unspecified, the simulator takes this error as the stopping criterion, it will run until the error precision is reached. It must be a value between 0.0 and 1.0. 7.4 Miscellaneous options IOP ELIMINATION This option specifies the method by how vanishing markings are managed and eventually eliminated. Specifying VAL REDNEVER means that the stochastic process being considered explicitly regards the vanishing markings as ordinary states. With this option, only a steady-state solution is possible. Using an embedded DTMC, measures related to immediate transitions are computed, and vanishing (non-absorbing) loops present no problems. Specifying VAL REDAFTERRG means that the reachability graph constructed includes explicitly the vanishing markings, but these are then eliminated numerically before generating the underlying CTMC. With this option, any type of solution is possible, and vanishing (non-absorbing) loops present no problems, but measures related to immediate transitions are not computed. Finally, specifying VAL REDONTHEFLY means that vanishing markings are eliminated during the reachability graph construction. With this option, any type of solution is possible, but vanishing (non-absorbing) loops are considered an error and measures related to immediate transitions are not computed. 58
