In today's competitive semiconductor business environment, wafer manufacturers are facing continuous pressure to accurately predict cycle time and tool utilization, gauge the impact of changes in capacity available, assess the impact of changes in product mix and quantity, and determine action plans to improve operational performance. Discrete event simulation (DES) is a widely used approach to perform such an analysis. However, DES has some inherent shortcomings for these planning tasks. Analytical models, like queueing networks, have much shorter response times and additional advantages compared to DES. But due to the complexity of semiconductor manufacturing systems (SMS) queueing models were not able to model all the peculiarities of those. This paper provides an overview of the main features of the IBM Enterprise Production planning and Optimization System (EPOS), a queueing network based system, which closes this gap. EPOS has been in use in the 300 mm fabrication of IBM in Fishkill for more than 2 years and has turned out to be an invaluable tool to analyze the trade-offs of cycle time and capacity within this complex environment.

This work presents a study undertaken to characterise the FINISTERRAE supercomputer, one of the biggest NUMA systems in Europe. The main objective was to determine the performance effect of bus contention and cache coherency as well as the suitability of porting strategies regarding irregular codes in such a complex architecture. Results show that: (1) cores which share a socket can be considered as independent processors in this context; (2) for big data sizes, the effect of sharing a bus degrades the final performance but masks the cache coherency effects; (3) the NUMA factor (remote to local memory latency ratio) is an important factor on irregular codes and (4) the default kernel allocation policy is not optimal in this system. These results allow us to understand the behaviour of thread-to-core mappings and memory allocation policies.

Since the beginning of human spaceflight, spacecraft designers have emphasized simplicity of design to minimize failures and have relied on a large ground staff to assist flight crews. As spacecraft and missions have grown in complexity, human workload has grown, keeping operational costs high and limiting productivity. A more progressive approach to automation can address these problems if risk can be reduced. We believe that a major contributor to risk of automation is weak architecture, leading to designs that are difficult to understand, analyze, verify, and operate. This paper explores architectural considerations of human-rated automation for space systems, where safety is paramount. Improved architectural concepts for automation are analyzed. We focus on goal-oriented control, and how goaloriented analysis and design address the concerns associated with increased automation.

Electric, hybrid-electric, and turbo-electric distributed propulsion technologies and concepts are beginning to gain traction in the aircraft design community, as they can provide improvements in operating costs, noise, fuel consumption, and emissions compared to conventional internal combustion or Brayton-cycle powered vehicles. The National Aeronautics and Space Administration (NASA) is building multiple demonstrators and testbeds to buy down airworthiness and flight safety risks for these new technologies, including X-57 Maxwell, Hybrid-Electric Integrated systems Testbed (HEIST), Airvolt, and NASA Electric Aircraft Testbed (NEAT). This paper addresses the safety system design process used at NASA Armstrong flight Research Center, specific hazards associated with these new electric propulsion technologies, including an extensive investigation into the emergency-stop system for a HEIST, and other best practices. In general, the best course of action is to actively design out hazards associated with these systems, but when removing these hazards is either impossible or impractical, other safety protocols including keep-out zones, lock-out/tag-out, and other practices should be implemented.

NAVAL ENGINEERS JOURNAL 1993年第3期105卷 152-166页

作者： ZAHN, PB ROSBOROUGH, J CARLSTROM, R Peter B. Zahn:is a section chief in the Naval Architecture Department at Advanced Marine Enterprises. He is responsible for software development and special trials support. He has led the Flooding Casualty Control Software (FCCS) development effort since joining AME in 1989. He is also responsible for the material handling strikedown and stowage (MHS&S) software development program as well as special trials support for the ACVLAP and T-AGOS 19 programs. Prior to joining AME Mr. Zahn spent nine years with various companies of the ARCTEC Group. His experience includes field trials in venues from the Caribbean to the Bering Sea as well as model tests and engineering design and development efforts. Mr. Zahn received his B.S. in naval architecture and marine engineering from Webb Institute in 1980 and has published various papers on pollution prevention offshore systems and icebreaker design and performance. He is a member of ASNE and SNAME. John Rosborough:has been a naval architect for the Naval Sea Systems Command (NavSea) for the past 15 years. He is currently assigned to the Hydrodynamics Division with responsibility for aircraft carrier stability evaluations and as a task leader for computer-aided ship design development. In the Stability Division he was previously responsible for stability analyses on various amphibious ships SWATHs and foreign ships. He manages the upgrade and augmentation of SHCP at NavSea and is the Navy's technical point of contact for evaluating shipboard stability software and transitioning technology to the fleet. Mr. Rosborough received his B.S. in naval architecture and marine engineering from the University of Michigan in 1977. He is a member of USNI and the Association of Scientists and Engineers at NavSea. Richard Carlstrom:is a naval architect with Advanced Marine Enterprises. He has been responsible for software development in support of a variety of major programs including FCCS and SHCP and is a specialist in stability evaluations for complex ships such as CVs CVNs

The Flooding Casualty Control software (FCCS) was developed under the auspices of the Naval Sea systems Command (NavSea) and is currently being deployed on a variety of ships in the neets of both the U.S. Navy and the U.S. Coast Guard. The primary objective of FCCS is to enable damage control personnel to identify critical stability conditions, especially when related to the loss of reserve buoyancy due to battle damage and the destabilizing effects of large quantities of firefighting water, in a timely manner. FCCS was initially deploved in 1990. It utilizes the standard algorithms of the Ship Hull Characteristics Program (SHCP). The user interface was designed to allow quick familiarity for shipboard users, primarily the damage control assistant (DCA) and his staff. Intact stability evaluations include the effects of topside icing, high winds, personnel crowding, heavy lifts over the side, high speed turns, and towing. FCCS also supports ballasting analysis for amphibious ships as well as providing bottom reaction and beached stability data for grounding incidents. Bv providing a tool for the ''fuel king'' and DCA to generate the required daily updates on the current ship load and liquids status, FCCS is assured of an accurate baseline in the event of damage. The design allows the evaluation of the ultimate ship stability status for a damage event using simple compartmentation and flooding status inputs. Evaluation of the adequacy of resulting stabilitv, as well as identification of such critical stability parameters as off center loading, margin line immersion, and negative GM, are accomplished by the program. Guidance is provided for the user to initiate appropriate flooding related damage control activities. Initially fitted on USS Oliver Hazard Perry Class frigates, FCCS databases have been for the USCG Hamilton class high endurance cutters, USS Arleigh Burke class Aegis destroyers, and a variety of other U.S. Navy and U.S. Coast Guard ship classes.

To establish a planning basis for future avionics systems, the Naval Air systems Command (NAVAIR) conducted an avionics architecture investigation during 1992-1993, culminating in a final report published in August 1993. In the course of the study, U.S. Industry provided significant information to a NAVAIR avionics database for both technologies and systems integration methods. From the study emerged an implementation strategy to allow NAVAIR to develop effective avionics systems in the future that use commercial products and standards where applicable but also allow the ready use of new and emerging technologies. Recommended strategies concentrate on the development process, especially the use of sound systems engineering techniques and the maximum practical use of commercial standards and products. This paper reviews the methodology employed during the NAVAIR investigation, and presents the key findings and resulting implementation strategies. The paper concludes with a brief summary of current implementation plans at NAVAIR.

The experimental ATM network services environment (EXPANSE) prototype provides an experimental testbed for multimedia multiparty telecommunications services over heterogeneous communications networks. The EXPANSE software architecture supports the functional separation of call and connection control. At the call control layer an object-oriented, transaction-based call model provides for the co-ordination of the negotiations among users for the establishment, modification and disconnection of telecommunications services. The connection control layer provides an object-oriented protocol for the dynamic establishment, modification and release of network connections which include the control and allocation of network resources required for multimedia multiparty services. The EXPANSE software includes an application programming interface (API) to the signalling protocol at the call control level. The API provides a uniform and powerful interface to the call model and allows different applications to co-ordinate the control of local resources and session state.

作者： Kristen Baldwin Dr. Charles Dickerson Dr. Abe Meilich John Osterholz Malcolm Touchin Dr. Steve Bratt Panelist Deputy Director Office of the Secretary of Defense (OSD) Software Engineering and System Assurance Office of the Deputy Under Secretary of Defense Acquisition and Technology Chair INCOSE Architecture Working Group (AWG) INCOSE AWG Leadership Team former Director BAE Systems Architecture and Interoperability for the DoD Chief Information Officer Technical Manager Systems Engineering Innovation Centre (SEIC) Loughborough University CEO W3C (invited) World Wide Web Consortium (W3C)

In May 2006, a task was issued by the U.S. Deputy Under Secretary of Defense for Acquisition and Technology (DUSD (A&T)) to develop a systems of systems engineering Guidebook. The Office of the Secretary of Defense (OSD) convened a small group of Government, Industry and Academia, and selected the Stevens Institute of Technology to lead the project. During the summer and autumn of 2006, the International Council on systems engineering (INCOSE) was honored to be invited to provide a global representation of the systems engineering community in support of the OSD writing of a systems of systems, systems engineering (SoS SE) Guide. On 22 December 2006 the draft SoS SE Guide, version 0.9, was released for review and use by the systems engineering community. Industry and academia have been asked to submit their comments as part of the effort to pilot the recommendations in the Guide. In 2007, OSD has been actively engaging a sample of DoD SoS programs to pilot the Guide, especially with respect to the 16 OSD SE processes. The responses will become part of the first update to the Guide. At this panel, OSD will present the background and motivation for writing the Guide, along with an update on the pilot. Both OSD and INCOSE will discuss their insights. As part of the broad SE community review, the Guide will also be viewed from the UK perspective of Capabilities Based Acquisition. Looking to the future, the concepts and practices of Net Centricity, Network Enablement of Capabilities, and Semantic Web will be considered and how they might be more deeply integrated into future versions of the Guide. This panel will provide opportunities for INCOSE to continue to work with OSD and collaborate on SoS SE.

作者： Baker, C Krull, R Snyder, G Lincoln, W Malone, TB Clifford C. Baker CIE CHFEP is a senior staff scientist at Carlow International Incorporated. He has applied most of his 24 years of experience in the application of human engineering technology to maritime systems. Mr. Baker has directed much of Carlow's efforts to reduce ship workload and to improve human performance and maritime safety through application of human factors methods and data. He is a Certified Industrial Ergonomist (CIE) as well as a Certified Human Factors Engineering Professional (CHFEP). Both certifications were granted by Oxford Research where Mr. Baker also serves as an Advisory Board member. Russell D. Krull P.E. is a senior engineer with A&T/Proteus Engineering with more than 18 years of experi-ence in marine engineering naval architecture and program management including 16 years of active duty in the U.S. Coast Guard. Recent experience includes advanced ship design studies engineering software development technical support for the USMC Advanced Amphibious Assault Vehicle propulsion systems analyses ship structural engineering and cargo handling systems engineering. Mr. Krull has an M.S.E. in naval architecture and marine engineering and an M.S.E. in industrial and operations engineering from University of Michigan and a B.S. in ocean engineering from the U.S. Coast Guard Academy. Capt. Glenn L. Snyder USCG. Regrettably since this paper was originally written Capt. Snyder has passed away. At the time of his death he was an operations specialist assigned to the Coast Guard's Deepwater Capabilities Replacement Project as Chief of Human Systems Integration. He served as commanding officer of the patrol boat Cape George (WPB-95306) the icebreaking tug Biscayne Bay (WTGB-104) and the cutter Legare (WMEC-911). A 1975 graduate of the U.S. Coast Guard Academy Capt. Snyder held an M.A. in national security and strategic studies from the U.S. Naval War College and an M.A. in international relations from Salve Regina College. In addition he was a 1998 fellow of the Foreign Service

The U.S. Coast Guard is in the concept exploration phase of its Integrated Deepwater System (IDS) acquisition project. This project will define the next generation of surface, air and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) assets used to perform the Coast Guard's missions in the IDS environment (>50 NM off the U. S. coastline). As part of early technology investigations, the needs exist to: (1) analyze the workload requirements of the IDS, (2) identify alternative means to perform ship's work, and (3) optimize ship manning consistent with ship workload, performance criteria, and the available tools and equipment aboard. To reduce shipboard work requires an understanding of the mission and support requirements placed on the vessel and crew, how these requirements are currently met, and how requirements might otherwise be met to reduce workload and crew size. This study examined currently implemented workload and manpower reducing approaches of commercial maritime fleets, U.S. and foreign navies, and foreign coastguards. These approaches were analyzed according to evaluation criteria approved by the IDS acquisition project team. From this, strategies for shipboard work reduction that may be considered for adoption by the IDS were identified and analyzed according to performance and costs factors. Ten workload-reducing strategies were identified: damage control, bridge, multiple crewing, engineering, risk acceptance, modularity, deck, enabling technologies, ship/personnel readiness, and operability and maintainability.
