  • Capabilities in Systems Engineering: an Overview
    Capabilities in Systems Engineering: An Overview Gon¸caloAntunes and Jos´eBorbinha INESC-ID, Rua Alves Redol, 9 1000-029 Lisboa Portugal {goncalo.antunes,jlb}@ist.utl.pt, WWW home page: http://web.ist.utl.pt/goncalo.antunes Abstract. The concept of capability has been deemed relevant over the years, which can be attested by its adoption in varied domains. It is an abstract concept, but simple to understand by business stakeholders and yet capable of making the bridge to technical aspects. Capabilities seem to bear similarities with services, namely their low coupling and high cohesion. However, the concepts are different since the concept of service seems to rest between that of capability and those directly related to the implementation. Nonetheless, the articulation of the concept of ca- pability with the concept of service can be used to promote business/IT alignment, since both concepts can be used to bridge different concep- tual layers of an enterprise architecture. This work offers an overview of the different uses of this concept, its usefulness, and its relation to the concept of service. Key words: capability, service, alignment, information systems, sys- tems engineering, strategic management, economics 1 Introduction The concept of capability can be defined as \the quality or state of being capable" [19] or \the power or ability to do something" [39]. Although simple, it is a powerful concept, as it can be used to provide an abstract, high-level view of a product, system, or even organizations, offering new ways of dealing with complexity. As such, it has been widely adopted in many areas.

Conclusions Glossary Bibliography Biographical Sketch Summary Cybernetics is a science that studies systems of any nature that are capable of perceiving, storing, and processing information, as well as of using it for control and regulation. UNESCO – EOLSS The second title of the Norbert Wiener’s book “Cybernetics” reads “Control and Communication in the Animal and the Machine”. However, it is not recognition of the external similaritySAMPLE between the functions of animalsCHAPTERS and machines that Norbert Wiener is credited with. That had been done well before and can be traced back to La Mettrie and Descartes. Nor is it his contribution that he introduced the notion of feedback; that has been known since the times of the creation of the first irrigation systems in ancient Babylon. His distinctive contribution lies in demonstrating that both animals and machines can be combined into a new, wider class of objects which is characterized by the presence of control systems; furthermore, living organisms, including humans and machines, can be talked about in the same language that is suitable for a description of any teleological (goal-directed) systems.

  • Need Means Analysis
    The Systems Engineering Tool Box Dr Stuart Burge “Give us the tools and we will finish the job” Winston Churchill Needs Means Analysis (NMA) What is it and what does it do? Needs Means Analysis (NMA) is a systems thinking tool aimed at exploring alternative system solutions at different levels in order to help define the boundary of the system of interest. It is based around identifying the “need” that a system satisfies and using this to investigate alternative solutions at levels higher, the same and lower than the system of interest. Why do it? At any point in time there is usually a “current” or “preferred” solution to a particular problem. In consequence organizations will develop their operations and infrastructure to support and optimise that solution. This preferred solution is known as the Meta-Solution. For example Toyota, Ford, General Motors, Volkswagen et al all have the same meta-solution when it comes to automobile – in simple terms two-boxes with wheel at each corner. All of the automotive companies have slowly evolved in to an industry aimed at optimising this meta-solution. Systems Thinking encourages us to “step back” from the solution to consider the underlying problem or purpose. In the case of an automobile, the purpose is to “transport passengers and their baggage from one point to another” This is also the purpose of a civil aircraft, passenger train and bicycle! In other words for a given purpose there are alternative meta-solutions. The idea of a pre-eminent meta-solution has also been discussed by Pugh (1991) who introduced the idea of dynamic and static design concepts.

  • Environmental Systems Analysis Tools for Decision-Making
    Environmental systems analysis tools for decision-making LCA and Swedish waste management as an example Åsa Moberg Licentiate thesis Royal Institute of Technology Department of Urban Planning and Environment Environmental Strategies Research Stockholm 2006 Titel: Environmental systems analysis tools for decision‐making LCA and Swedish waste management as an example Author: Åsa Moberg Cover page photo: Marianne Lockner TRITA‐SOM 06‐002 ISSN 1653‐6126 ISRN KTH/SOM/‐‐06/002‐‐SE ISBN 91‐7178‐304‐0 Printed in Sweden by US AB, Stockholm, 2006 2 Abstract Decisions are made based on information of different kinds. Several tools have been developed to facilitate the inclusion of environmental aspects in decision‐making on different levels. Which tool to use in a specific decision‐making situation depends on the decision context. This thesis discusses the choice between different environmental systems analysis (ESA) tools and suggests that key factors influencing the choice of ESA tool are object of study, impacts considered and information type regarding site‐specificity and according to the DPSIR‐framework. Waste management in Sweden is used as an example to illustrate decision‐making situations, but discussions concerning choice of tools are also thought to be of general concern. It is suggested that there is a need for a number of ESA tools in waste management decision‐making. Procedural tools like Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) should be used e.g. by companies applying for development of waste management facilities and by public authorities preparing plans and programmes. Within these procedural tools analytical tools providing relevant information could be used, e.g.

The objectives of the program are to: significantly increase safety and reliability, reduce the cost of accessing low-earth orbit, attempt to leverage commercial launch capabilities, and provide a growth path for manned space exploration. The safety, reliability and life cycle cost of the next generation vehicles are major concerns, and NASA aims to achieve orders of magnitude improvement in these areas. To get these significant improvements, requires a rigorous process that addresses Reliability, Maintainability and Supportability (RMS) and safety through all the phases of the life cycle of the program. This paper discusses the RMS process being implemented for the Second Generation RLV program. 1.0 INTRODUCTION The 2nd Generation RLV program has in place quantitative Level-I RMS, and cost requirements [Ref 1] as shown in Table 1, a paradigm shift from the Space Shuttle program. This paradigm shift is generating a change in how space flight system design is approached.

  • What's in a Mental Model of a Dynamic System? Conceptual Structure and Model Comparison
    What’s in a mental model of a dynamic system? Conceptual structure and model comparison Martin Schaffernicht Facultad de Ciencias Empresariales Universidad de Talca Avenida Lircay s/n 3460000 Talca, CHILE [email protected] Stefan N. Groesser University of St. Gallen Institute of Management System Dynamics Group Dufourstrasse 40a CH - 9000 St. Gallen, Switzerland Tel: +41 71 224 23 82 / Fax: +41 71 224 23 55 [email protected] Contribution to the International System Dynamics Conference 2009 Albuquerque, NM, U.S.A. Abstract This paper deals with the representation of mental models of dynamic systems (MMDS). Improving ’mental models’ has always been fundamental in the field of system dynamics. Even though a specific definition exists, no conceptual model of the structure of a MMDS has been offered so far. Previous research about the learning effects of system dynamics interventions have used two methods to represent and analyze mental models. To what extend is the result of these methods comparable? Can they be used to account for a MMDS which is suitable for the system dynamics methodology? Two exemplary MMDSs are compared with both methods. We have found that the procedures and results differ significantly . In addition, neither of the methods can account for the concept of feedback loops. Based on this finding, we propose a conceptual model for the structure of a MMDS, a method to compare them, and a revised definition of MMDS. The paper concludes with a call for more substantive research. Keywords : Mental models, dynamic systems, mental model comparison, graph theory, mental model measurement Introduction Mental models have been a key concept in system dynamics from the beginning of the field (Forrester, 1961).

  • Control Theory
    Control theory S. Simrock DESY, Hamburg, Germany Abstract In engineering and mathematics, control theory deals with the behaviour of dynamical systems. The desired output of a system is called the reference. When one or more output variables of a system need to follow a certain ref- erence over time, a controller manipulates the inputs to a system to obtain the desired effect on the output of the system. Rapid advances in digital system technology have radically altered the control design options. It has become routinely practicable to design very complicated digital controllers and to carry out the extensive calculations required for their design. These advances in im- plementation and design capability can be obtained at low cost because of the widespread availability of inexpensive and powerful digital processing plat- forms and high-speed analog IO devices. 1 Introduction The emphasis of this tutorial on control theory is on the design of digital controls to achieve good dy- namic response and small errors while using signals that are sampled in time and quantized in amplitude. Both transform (classical control) and state-space (modern control) methods are described and applied to illustrative examples. The transform methods emphasized are the root-locus method of Evans and fre- quency response. The state-space methods developed are the technique of pole assignment augmented by an estimator (observer) and optimal quadratic-loss control. The optimal control problems use the steady-state constant gain solution. Other topics covered are system identification and non-linear control. System identification is a general term to describe mathematical tools and algorithms that build dynamical models from measured data.
