In this paper, we present a new approach that can further enhance the efficiency of ordinal optimization. Our approach intelligently determines the optimal number of simulation replications (or samples) and significantly reduces the total simulation cost. Numerical illustrations are included. The results indicate that our approach can obtain an additional 74% computation time reduction above and beyond the reduction obtained through the use of ordinal optimization for a 10-design example.

  • Perturbation analysis of stochastic Petri nets

    This paper addresses the sensitivity analysis of stochastic Petri nets (SPNs) using simulations. The goal is to evaluate the derivatives of performance measures with respect to timing parameters. To characterize the underlying stochastic processes of SPNs, we use a generalized semi-Markov process (GSMP) representation and propose a new representation, called GSMP*, which differs from GSMP in the routing mechanism. By using existing results on perturbation analysis of GSMPs and by extending them to GSMP*, unbiased sensitivity estimators are obtained for SPNs simulated under a GSMP or GSMP* framework. Most importantly, we prove that only one simulation run is needed for evaluating both the performance measures and their derivatives for a class of free-choice nets simulated under a GSMP framework and for any free-choice net simulated under a GSMP* framework.

  • Virtual space

    The Parallel (and Distributed) Discrete Event Simulation (PADS) community - over it's more than 20 years of existence - has achieved remarkable results in getting the execution of simulations of discrete event systems faster, involving multiple, logically and/or physically dispersed, communicating computational resources. A solid, mature and empirically approved body of foundational concepts, models, systems, methods and algorithms are at hand and well documented in more than 50.000 pages of research papers. PADS simulation engines, model and software libraries, and operating systems have proven feasibility and applicability of these results in solving real world problems. Despite the (healthy) self-criticism of it's proponents ("Will the field survive?"), PADS was - and is - a success! With this talk we aim at a prospect for the challenges posed by the emerging new models of computational and communication, the evolving new paradigms of interaction and coordination, the new styles of system design, and even the availability of new technologies, for which - in my opinion - no other community qualifies better than the PADS community.

  • Abstract simulators for the DSDE formalism

    We present the DSDE (Dynamic Structure of Discrete Events) formalism, a methodology for representing discrete event systems that change structure dynamically. We prove that the DSDE formalism is closed under coupling and that it can be used to construct hierarchical and modular models. The abstract simulators which are necessary to execute dynamic structure models are also presented. These simulators allow a description of models independent of the actual simulation procedure, and thus encourage model reuse.

  • A model for real-time simulation of large-scale networks based on network processor

    Real-time network simulation refers to simulating computer networks in real time so that the virtual network can interact with real implementations of network protocols, network services, and distributed applications. This paper proposes a new model for real-time simulation of large-scale networks based on powerful network processor. The scheme takes advantage of discrete event system simulation model to simulating large-scale network. This paper describes the implementation of network simulation technology based on Intel IXP2400 platform. Experiment results show that the model can simulate large- scale network, learn routing entries automatically and forward packets at wire-speed.

  • Rates of convergence for budget dependent stochastic optimization algorithms

    This paper is concerned with convergence rates of stochastic optimization algorithms depending on the budget. The underlying problems naturally arise from a wide range of applications in Monte Carlo optimization and discrete event systems, for example, optimization of steady-state simulation models with likelihood ratio, perturbation analysis, or finite-difference gradient estimators, optimization of infinite-horizon models with discounting etc. Frequently, one wants to minimize a cost functional /spl alpha/(/spl middot/) over IR/sup r/. We are mainly interested in the situation where the value of /spl alpha/(/spl theta/) for a /spl theta//spl isin/IR (or its gradient) is difficult to compute, and only a gradient estimator is available, which can be computed by simulation. The quality of the estimator may depend on the parameter value /spl theta/ and the computing budget. Assuming that a gradient estimator is available and that both the bias and the variance of the estimator are functions of the budget, we use the gradient estimator in conjunction with a stochastic approximation (SA) algorithm. Our interest is to figure out, how to allocate the total available computational budget to the successive SA iterations. We find the convergence rates in terms of the number of iterations, and the total computational effort. Our results are also applicable to root-finding stochastic approximations.

  • Analytic perturbation analysis of discrete event dynamic systems

    This paper considers a new analytic perturbation analysis (APA) approach for discrete event dynamic systems (DEDS) with discontinuous sample-path functions with respect to control parameters. The performance functions for DEDS usually are formulated as mathematical expectations, which can be calculated only numerically. APA is based on new analytic formulas for the gradients of expectations of indicator functions, therefore, it is called an analytic perturbation analysis. The gradient of performance function may not coincide with the expectation of a gradient of sample-path function (i.e., the interchange formula for the gradient and expectation sign may not be valid). Estimates of gradients can be obtained with one simulation run of the models.<<ETX>>

  • Method and Implementation for Consistency Verification of DEVS Model against User Requirement

    In this study, we propose a new method to assist the consistency verification of a discrete event simulation model, specified by DEVS formalism, against user requirement specification, expressed in natural language. Our approach is composed of successive steps of consistency verification. The first is the validity check of UML diagrams against the user requirement specification. The second step is verification of event sequences between an UML diagram and a DEVS model. The proposed verification method has been implemented in an automated tool named VERIDEVS. Inputs to VERIDEVS are UML diagrams and DEVS Graph, and outputs are verification result tables. VERIDEVS consists of a drawing element parser, activation composer, state composer, sequence generator, and sequence comparator.

  • A framework for hybrid modeling/simulation of discrete event systems

    This paper presents a hybrid modeling/simulation framework within which both accuracy in models and speed in simulation experimentations are obtained. Based on the Zeigler's DEVS formalism and associated system theory, the framework is based on the transformation of selected DEVS model into equivalent analytic ones to simulate both analytic and simulation models within a single environment. For high-speed hybrid simulation, the authors extended DEVSim++ which is a realization of the DEVS formalism in C++. To exemplify the proposed approach, the authors demonstrate performance modeling and simulation of a simple communication network.<<ETX>>
