Model-Based Design of Defense Cyber-Physical Systems to Analyze Mission Effectiveness and Network Performance

Abstract

This paper discusses two modeling and simulation (M&S) issues for defense cyber-physical systems (CPSs): 1) model-driven development via model interoperation and 2) simulation analysis between interoperated models. To clearly describe the network capabilities between the CPSs within network-centric warfare (NCW), we first modeled communication factors separately from the overall CPSs. The CPS models and the network model were considered discrete event systems, which were realized with DEVSim++ and ns-3, respectively. For the simulation of the two types of models, we interoperated them with high-level architecture-based middleware to preserve the independence of each one. The goal for NCW analysis is to find a balance between the computational, physical, and communication factors of the defense CPSs to achieve their missions within a networked environment. In the case study of network-centric ground warfare, the CPS models generate mission effectiveness to be analyzed according to realistic network conditions; and at the same time, the network model enables the analysis of the network performance given validated combat scenarios. We expect this paper will help simulation experts interactively analyze computational and physical capabilities of the CPSs as well as communication effects between the CPSs.INDEX TERMS Network-centric warfare, system of systems, discrete event system, model interoperation, linear regression analysis, measure of effectiveness, measure of performance.

A Simulation Budget Allocation Procedure for Finding Both Extreme Designs Simultaneously in Discrete-Event Simulation

“…Compared to the OCBAbw procedure, the higher robustness of the proposed procedure is attributed to considering additional information when allocating further replications. Although both procedures take into account the sample meanμ i and the sample variance s 2 i , the proposed procedure considers the number of collected samples N i as well, as shown in (8). However, the OCBAbw procedure uses onlyμ i and s 2 i as specified in its main allocation rule below [21]:…”

“…Discrete-event simulation is widely used to analyze modern industrial complex systems, such as manufacturing [1], military [2], smart grid [3], telecommunications [4], and transportation [5]. The most significant advantage of the simulation is that, with just a few assumptions, it can accurately analyze complex systems that cannot be described using closed-form analytic models [6].…”

A Time Domain-Based Iterative Method for Helicopter Maritime Search Area Planning and Construction of the Simulation Environment

“…Niping Jia et al proposed an operational effectiveness evaluation method of a swarming UAV combat system based on a system dynamic model [23]. Bong Gu Kang et al used discrete event simulation to analyze the mission effectiveness and network performance of defense cyber-physical systems [24]. In this paper, an agent-based simulation environment for maritime search missions was constructed.…”

Enhancing the Noise Robustness of the Optimal Computing Budget Allocation Approach

“…Discrete-event system simulation is a powerful tool for analyzing modern industrial systems such as telecommunication [1], manufacturing [2], microgrid [3], transportation [4], healthcare [5], and military [6] systems that cannot be described as a closed-form analytic model [7]. As one of the essential applications of simulation, simulation-based optimization (SBO) finds the optimal configurations of the systems' decision variables (i.e., the optimal designs) that satisfy the given optimal requirements of the system performance (e.g., maximize the performance) using simulations [8].…”
