CONTENTS: 1) Geriatric Issues of Aging Software by Capers Jones: Capers Jones discusses the need of every company to evaluate and consider best practices for maintenance and to avoid common worst practices. 2) Performance-Based Software Sustainment for the F-35 Lightning II by Lloyd Huff and George Novak: This article describes some of the revolutionary conclusions and products of an analysis of the sustainment for the F-35 and provides a look ...
This paper presents a high-level modeling and simulation (M&S) approach that is intended to be used early in the systems engineering lifecycle. The approach leverages behavior modeling techniques for designing executable function flows (i.e. functional simulation). It is built on system architecture products (such as DoD Architecture Framework (DoDAF) products) and is referred to as Executable Architecture (EA). EA is designed to provide a higher-level view or abstraction of certain ...
This briefing presents an architecture modeling approach for service-oriented architectures such as the Net-Centric Enterprise Services (NCES). The approach is driven by operational mission threads. It uses Unified Modeling Language and the Department of Defense Architecture Framework to capture, analyze, and present the architecture products. Steps in this approach include: 1. Formulating activity models for a mission thread. 2. Mapping the activities to NCES and existing systems. 3. Developing logical ...
