Resilience Assessment

AbstractOrganizational and technical approaches have proven successful in increasing the performance and preventing risks at socio-technical systems at all scales. Nevertheless, damaging events are often unavoidable due to a wide and dynamic threat landscape and enabled by the increasing complexity of modern systems. For overall performance and risk control at the system level, resilience can be a versatile option, in particular for reducing resources needed for system development, maintenance, reuse, or disposal. This paper presents a framework for a resilience assessment and management process that builds on existing risk management practice before, during, and after potential and real events. It leverages tabular and matrix correlation methods similar as standardized in the field of risk analysis to fulfill the step-wise resilience assessment and management for critical functions of complex systems. We present data needs for the method implementation and output generation, in particular regarding the assessment of threats and the effects of counter measures. Also included is a discussion of how the results contribute to the advancement of functional risk control and resilience enhancement at system level as well as related practical implications for its efficient implementation. The approach is applied in the domains telecommunication, gas networks, and indoor localization systems. Results and implications are further discussed.

The Impact

In this paper, we introduce a new risk-informed decision-making methodology for use during early design of complex systems. The proposed approach is based on the notion that a failure happens when a functional element in the system does not perform its intended task. Accordingly, risk is defined depending on the role of functionality in accomplishing designed tasks. A simulation-based failure analysis tool is used to analyze functional failures and their impact on overall system functionality. The analysis results are then integrated into a decision-making framework that relates the impact of functional failures and their propagation to decision making in order to guide system level design decisions. With the help of the proposed methodology, a multitude of failure scenarios can be quickly analyzed to determine the effects of decisions on overall system risk. Using this decision-making approach, design teams can systematically explore risks and vulnerabilities during early, functional stage of system development prior to the selection of specific components. Application of the presented method to a reservoir system design demonstrates these capabilities.

The Air Force is fielding a computer-based command and control system to support fighter base mission requirements. The acquisition strategy for this system was to purchase it as a Non-Developmental Item (NDI). Since the hardware and software were in the Air Force inventory, it was determined that system development was not necessary. Initial implementation and installation occurred without system-level specifications or performance requirements. This paper presents the results of a Human Factors Engineering evaluation of the system from three perspectives: an Expert's view, a Military Standard view, and a User's view. Two primary lessons resulted from the evaluation: First, the multi-perspective evaluation technique is valuable and highly recommended for use in other HFE evluations. Second, the purchase of NDI or commercial off-the-shelf (COTS) items should be viewed from the systems perspective, i.e., even though subsystems may be NDI, the system may be developmental.

Under the current trend of globalization, companies develop products not only to target a single market but to sell them to the entire world. Companies realize the importance of collaborative design, or workshare, to develop global regional engineering centers to balance design variations while ensuring local market success. This paradigm shift enables diverse customer values to be integrated into products but also introduces challenges in the management of work distribution. Extensive industry case studies have shown that capability and capacity of the regional centers drive the workshare decisions; however, this strategy overlooks the interdependence of the design systems causing many delays and quality problems. Seeing the opportunity, this paper presents a method to identify and to quantify the system-level workshare risk based on the couplings of system components to evaluate the overall workshare scenarios. The risk analysis consists of two key elements in terms of two relationships, the division of work for distributions (i.e., component coupling) and the work assignments of the distributed teams (i.e., workshare coupling), as well as an algorithm to combine the relationships to calculate the workshare risk. To illustrate the steps of the risk analysis, this paper applies it to a hair dryer design as a case study. The paper also discusses the usages and characteristics of the risk analysis, and concludes with the future research and the next steps of generalizing the method to other product development projects.

E-commerce is a very rapid development of trade in various fields, including pharmaceuticals. One process is the provision of prescription or non-prescription drugs from pharmacies. The management practice is still done manually, which involves the buying and selling process in person. Besides, processing and drug supplies are also done manually. These reasons make the process less effective and efficient, so it is necessary to develop an information system in buying and selling (e-commerce), improving performance, and reaching the target market. This system development uses the SDLC (System Development Live Cycle) concept and e-commerce, specifically in the pharmaceutical sector. This process is carried out from requirements to testing. The development is an e-commerce website that can help in the pharmacy's buying and selling process. Besides, the website is capable of connecting with customers. The system can integrate existing supplies into a pharmacy information system. The design of this system uses the programming languages PHP and MySQL. The results were tested using the Black Box method with the results that all processes and functions performed were carried out correctly. The developed website can be implemented in e-commerce at the pharmacy.

Case management is used within a broad range of human services programs. The author examines case-management practice from a systems perspective, exploring interorganizational issues and case managers' fiscal authority. Case managers' potential to produce systems change has been underdeveloped because most case managers cannot influence the distribution, type, and supply of resources within their local delivery systems. Strategies designed to enhance case managers' system-level effectiveness are discussed. Program examples in mental health, community-based long-term care, and health care are analyzed.

The Advanced Dish Development System (ADDS) project is an advanced, system-level dish/Stirling solar power system development activity aimed at the remote power marketplace. Unlike any of the other U.S. Department of Energy (DOE) Concentrating Solar Power (CSP) program sponsored activities, the ADDS project is being integrated by Sandia National Laboratories (SNL). Although SNL and the National Renewable Energy Laboratory (NREL) help the DOE manage the CSP program, previous system development activities were all integrated by industry partners, with SNL and NREL providing technical support. The ADDS project is a technology development activity with the specific objective of fielding a remote, off-grid, water-pumping dish/Stirling system on an Indian reservation in the Southwestern U.S. To meet this objective, the WGAssociates (WGA) solar concentrator and controls, and the SOLO 161 Stirling Power Conversion Unit (PCU) were selected for the major components. The WGA concentrator and controls technology are well advanced and utilize structural facet mirror technology and concentrator structure and controls technology developed over decades with DOE and private investment. The SOLO 161 Stirling PCU, including solar receiver and controls, has also benefited from decades of development. Two ADDS designs have been developed. A first-generation (Mod 1) grid-connected prototype system was fielded at the National Solar Thermal Test Facility (NSTTF) in Albuquerque, NM in the summer of 1999, primarily for the purpose of reliability improvement. In 2000, an upgraded, second-generation (Mod 2) system, including a standalone water-pumping ADDS was developed, and in 2001 it was installed and demonstrated at the NSTTF. While the value of remote power electricity is greater than for utility power, (estimates range from 20 to more than 50 cents per kilowatt-hour) the remote environment presents additional requirements. The ADDS project has been a first step in the development and demonstration of a dish/Stirling system that can potentially address this large commercial opportunity. Integration of the ADDS has also been challenging and rewarding. As a result of the ADDS project, insights beyond specific component expertise have been obtained. Even though we have not been able to achieve our original objective of fielding a dish/Stirling system on an Indian reservation because of reduce budgets, the ADDS project has been successful in that most of the original system specifications and technical objectives were met or exceeded. It has also served as a valuable test bed for the evaluation of advanced technology in a system context. The ADDS technology and results are presented in other papers. In this paper, the integration philosophy and approaches utilized in the various stages of the ADDS project are presented and described. Insights gained from integration of the ADDS are also discussed.

The Future

This paper identifies a significant emerging problem in the definition and development of future ATC system enhancements. Metaprototyping (prototyping at the system level) in the Integration and Interaction Laboratory (I-Lab) will allow the FAA to initiate a new process for RE&D of the future NAS that will support the active involvement of system operators and users. Initial simulation studies have begun and will continue to address interaction among planned, future ATC automation programs in support of the people within the NAS. Preliminary results form these studies and the process for the conduct of metaprototyping will be described. The key difference between the I-Lab effort and previous prototyping is the integration of concepts, models and system elements within the context of the future system as opposed to prototyping of individual components or system elements. The I-lab is a tool for systems engineering and research activities to envision the future and guide development to achieve that vision. At each step the resulting information will be used to support the FAA's efforts to establish and maintain a future system definition and relevant research and development programs to achieve enhanced efficiency for the end-users, and NAS resources and personnel. In addition, the process by which system prototyping is effected will be established including the roles of RE&D organizations, outside researchers, operational personnel, and system users.

In the Midwest U.S. dominated corn-soybean landscape, agroforestry systems can be particularly valuable for increasing the provisioning and regulatory capacity of the agricultural landscape. However, these systems have not yet been broadly integrated into the landscape of this region since they are mostly relegated to marginal lands. A growing body of literature suggests a path to increase the adoption of agroforestry in the Midwest U.S. lies in the incorporation of low-input food-producing tree species that provide economic incentives for farmers. Studies of the system-level integration of such approaches have proceeded by using the currently available cultivars and breeding selections of various tree nut and fruit species. While existing varieties and breeding selections provide the opportunity for initial system development and integration, their broad adaptability to the Midwest U.S. and its marginal land-types is unexplored. Thus, a second tier of research includes the genetic improvement and adaptation of tree crop selections to their respective target environments throughout the Midwest U.S. Fortunately, select tree crops of interest are amendable to systematic breeding and have wild relatives that are endemic across the region. In this paper, we discuss the value of these wild relatives for broadening the adaption of cultivated tree crop selections by using the hazelnut as an example species. We present a framework using geospatial tools to define and prioritize target environments for breeding and, in turn, exploiting wild relative germplasm.
