Military Information Operations Analysis Using Influence Diagrams and Coloured Petri Nets

Abstract: : This report describes how Influence Diagrams, Coloured Petri Net models and related techniques may be used to analyse certain aspects of Military Information Operations. An example is employed to demonstrate these techniques. The example used is a very simplified representation of a Military Command Organisation dealing with a decision problem. The objective of the report is to provide theory, methods and techniques to support the assessment of the effect of Military Information Operations on such organisations. The simplicity of the example permits the basic concepts to be clearly conveyed. They may readily be extended to the analysis of more complex examples as required. The most fundamental and significant concept developed in this report is that of a common quantitative measure of effectiveness that encompasses all types of Information Operations relevant to Information Warfare. This permits the direct comparison of the effectiveness of alternative Information Operation options with one another and also with conventional operations options. This latter ability is essential if Information Operations are to be employed appropriately as part of a broader range of military options.

Concept Design Using Model Based Systems Engineering

Abstract: The value of analytical modeling when performing concept design cannot be overstated. Using a concurrent engineering process and interconnected analytical tools to estimate system size, mass, power, performance, resilience, and cost, engineers can rapidly develop concepts to perform feasibility assessments and configuration trade studies. Perhaps less clear is of the value of descriptive modeling offered by Model Based Systems Engineering (MBSE) practice applied to concept design. Currently there are precious few examples of acquisition programs implementing MBSE across all life cycle phases, and fewer examples of programs that use it during concept development. Concept developers use analytical tools to analyze candidate systems during this phase, but they also need to deal with other aspects of system design such as mission objectives, system requirements, concept of operations, system architecture, and function allocation. These attributes may all be captured and interconnected in a descriptive system model, which is at the very core of MBSE practice. It is shown here how system developers can create and use such a descriptive system model in conjunction with their analytical concurrent engineering tools to rapidly develop concept designs.

A demonstration of the integrated supportability analysis and cost system (ISACS

Abstract: This paper describes the Integrated Supportability Analysis and Cost System (ISACS+) and the features which will be demonstrated. ISACS+ is a distributed, client/server system for evaluating operation and support characteristics of weapon systems and, in future builds, commercial aircraft systems. This tutorial briefly describes the ISACS+ Concept of Operations and how Operation and Support studies are conducted using the ISACS+ tool. This tutorial also describes the architecture used to distribute the ISACS+ software over multiple computing tiers in support of the concept of operations.

On the estimation of operations and maintenance costs for defense systems

Abstract: The estimation of operations and maintenance (O&M) costs for weapon systems has been termed `infeasible' due to: 1) a lack of detailed prior (O&M) costs, 2) a large amount of uncertainty in the operational tempo for the system, and 3) uncertainty in the predicted reliability of system components. This research proposes the creation of a flexible discrete event simulation model to estimate O&M costs by predicting events that occur during a system's life cycle. Such a model takes as inputs a given concept of operations, maintenance strategy, and system reliabilities to determine lifecycle events such as: consumables used and maintenance operations performed on the entire system throughout its life cycle. The uncertain cost of each event can be used to estimate a distribution of total O&M costs. The results can finally be analyzed to determine the attribution of the uncertainty of those costs to all of the different possible sources.

Multi-Domain Modeling and Simulation of an Aircraft System for Advanced Vehicle-Level Reasoning Research and Development

Abstract: In this paper, we describe a simulation based health monitoring system test-bed for aircraft systems. The purpose of the test-bed is to provide a technology neutral basis for implementing and evaluation of reasoning systems on vehicle level and software architecture in support of the safety and maintenance process. This simulation test-bed will provide the sub-system level results and data which can be fed to the VLRS to generate vehicle level reasoning to achieve broader level diagnoses. This paper describes real-time system architecture and concept of operations for the aircraft major sub-systems. The four main components in the real-time test-bed are the aircraft sub-systems (e.g. battery, fuel, engine, generator, heating and lighting system) simulation model, fault insertion unit, health monitoring data processing and user interface. In this paper, we adopted a component based modelling paradigm for the implementation of the virtual aircraft systems. All of the fault injections are currently implemented via software. The fault insertion unit allows for the repeatable injection of faults into the system. The simulation test-bed has been tested with many different faults which were undetected on system level to process and detect on the vehicle level reasoning. This article also shows how one system fault can affect the overall health of the vehicle.
