Atenção especial tem sido dada às atividades de documentação e suporte a projetos em Engenharia de Software, principalmente quando estão relacionadas a sistemas complexos e equipes distribuídas. Geralmente apenas se registram as informações relativas às decisões finais de determinada fase. Não são documentadas as razões de cada decisão e nem as alternativas que foram consideradas e descartadas. A captura e recuperação, de maneira eficiente, deste tipo de informação é a finalidade do estudo do Design Rationale. O registro destas informações pode facilitar a manutenção, o reuso e também a própria fase de elaboração do projeto, na medida em que possibilita um melhor entendimento do sistema, por meio da disseminação de conhecimento, comunicação e integração entre a equipe de projeto. A questão é quando e como capturar estas informações sem muita interferência junto às atividades usuais dos projetistas, a fim de que os benefícios possam superar os custos envolvidos nesta tarefa. O presente trabalho tem como objetivo mostrar com razões plausíveis a grande utilidade da aplicação da técnica de Design Rationale em projetos de sistemas ERP, propondo um novo modelo de representação das decisões de projeto para estes sistemas.; Special attention has been given to documentation and support activities in Software Engineering design...

Production systems design is critical to achieving manufacturing performance and objectives. Although generic approaches to this design are available they may not be able to objectively address specific manufacturing configurations. Here it is argued that product oriented manufacturing (POM) organization offers advantages in relation to the function oriented one. Based on this, a methodology specially addressing POM systems design, and prototype of a Computer Aided Design System based on the methodology were develop. A brief description of both is presented.

The design of production and logistic systems is a process of managing both technical and organisational variants in order to identify the best solution for a given system. This paper discusses design issues of production systems that are applied to an internal logistic system in the automotive industry. As far as the production systems design (PSD) is concerned, three basic classes of software tools usually pertain: computer-aided design (CAD), process simulation, and information systems. However, these software tools have been used with low levels of integration. Vik et al. (2010b, 2010c) proposed integrating these software resources in production systems and developed an advanced tool called integrated design of systems (IDS). The proposed IDS tool involves a wide set of functions for the most common tasks of PSD, from conceptualisation to implementation, including systems analysis (P-Q, cluster, and material flow analysis), automatic generation of simulation models, generation of alternatives for the layout of facilities and factories, material flows display, transportation system design, and iterative buffer size specification. The IDS approach takes advantage of simulation, CAD systems, and their integration. This paper will demonstrate the concept and functionalities of the proposed tool in a real industrial case study.; Fundação para a Ciência e Tecnologia

This paper discusses production systems design issues, applied to the production system layout of a manufacturer of lighting fittings and components. In this paper, production systems design software tools – Information Systems, Simulation and Computer Aided Design are integrated, exploring ways of dealing with data diversity and assuring valid and efficient production system layouts, taking advantage of the mentioned data integration. This integration is implemented on Microsoft Access (databases with system knowledge repository), AutoCAD (layout design) and WITNESS (simulation). The software package developed was called IDS (Integrated Design of Systems). This approach can help on global system optimization that considers all important system resources and system performance measures. Solutions are expected to be faster to achieve and better than solutions obtained with non-integrated approaches. IDS approach is open and accessible, thus enabling different companies to use this advanced production systems design tool, taking advantage of simulation and CAD systems and their integration. This application intends to validate the concept and functionalities of the proposed tool, on a real industrial case study.; This work has been supported by FCT – Fundação para a Ciência e Tecnologia (algoritmi)

Education and training are important elements in patient safety, both as a potential contributing factor to risks and hazards of healthcare associated injury or harm and as an intervention to be used in eliminating or preventing such harm. All too often we have relied on training as the only interventions for patient safety without examining other alternatives or realizing that, in some cases, the training systems themselves are part of the problem. One way to ensure safety by design is to apply established design principles to education and training. Instructional systems design (ISD) is a systematic method of development of education and training programs for improved learner performance. The ISD process involves five integrated steps: analysis, development, design, implementation, and evaluation (ADDIE). The application of ISD using the ADDIE approach can eliminate or prevent education and training from being a contributing factor of health associated injury or harm, and can also be effective in preventing injury or harm.

This research develops a comprehensive approach to identify and deal with real options in" projects, that is, those real options (flexibility) that are integral parts of the technical design. It represents a first attempt to specify analytically the design parameters that provide good opportunities for flexibility for any specific engineering system. It proposes a two-stage integrated process: options identification followed by options analysis. Options identification includes a screening and a simulation model. Options analysis develops a stochastic mixed-integer programming model to value options. This approach decreases the complexity and size of the models at each stage and thus permits efficient computation even though traditionally fixed design parameters are allowed to vary stochastically. The options identification stage discovers the design elements most likely to provide worthwhile flexibility. As there are often too many possible options for systems designers to consider, they need a way to identify the most valuable options for further consideration, that is, a screening model. This is a simplified, conceptual, low-fidelity model for the system that conceptualizes its most important issues. As it can be easily run many times...

Naval ship design and construction has been in existence for thousands of years. Over that time, many tools have been developed to aid naval architects in the quest for an optimal design, whether fast and sleek like a racing boat or big and square like an oil tanker. In any case, the basic naval architecture design principles are the same. The following thesis discusses the use of systems engineering principles, including the Pugh concept selection tool and design spiral methodology. Additionally, Chapter 3 provides an example of those principles and methods as they are applied to the hull design for a high-speed naval vehicle. The combination of system engineering principles and methods provided a rapid convergence to a feasible hull design that exemplified the methods taught in the Systems Design and Management program. Furthermore, recommendations are made for the future of naval vessel design through the use of genetic algorithms for an accurate representation of the value of "real options" as they may apply to marine vessel design.; by William L. Hagan, III.; Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2008.; Includes bibliographical references (leaves 64-66).

This thesis seeks to offer an answer to the problem of how to design, implement and support information systems that effectively and efficiently support e-learning within universities. This problem is increasingly prevalent and important to the operation of universities. It is also a problem where existing solutions are limited in terms of variety, quality and explicit theoretical guidance. This thesis formulates a specific Information Systems Design Theory (ISDT) “An Information Systems Design Theory for Emergent University E-learning Systems“ as one answer to this problem. The ISDT is formulated using an iterative action research cycle that encompasses the design, support and evolution of the Webfuse information system at Central Queensland University (CQU) from 1996 through 2009. The Webfuse system was used by tens of thousands of staff and students. It is the knowledge gained through this experience that, in two separate stages, is used to formulate design theory. The final ISDT recognises that diversity and rapid on-going change are for a number of reasons, the key characteristics of e-learning within universities. Consequently, the ISDT specifies both process and product models that aim to enable the e-learning information systems to be emergent. In particular the ISDT proposes that emergent e-learning information systems will encourage and enable greater levels of e-learning adoption in terms of quantity...

Thesis (PhD) - Indiana University, School of Education, 2008; Increased use of computing technology in support of learning necessitates the collaboration of instructional designers with technology designers. Yet the instructional designer portrayed in current instructional design textbooks does not participate in technology design but instead designs instructional strategies and materials that are implemented by others. For instructional systems design as a field to move towards the kinds of collaborative work required for the development of effective, innovative educational technologies, there is a need for methods that can integrate the concerns and activities of both instructional and technology designers. This research critically examines a human-computer interaction design method, contextual design (CD), assessing how practitioners employ and characterize it as a method and explores its potential utility in instructional systems design. CD is briefly described and available evaluative studies are summarized. Next, three studies are presented: a case study of CD usage in the design of a digital music library, a case study of CD integrating with another design approach called PRInCiPleS, and a learning-oriented analysis of CD work models. Based on the findings of the literature review and these three studies...

The design of production and logistic systems is a process of managing both technical and organizational variants in order to identify the best solution for a given system. This is a very well-known industrial engineering issue, where the objectives for designing such a system have been changing over the last decades. Former approaches were concerned about material handling costs only but more recent works include re-layout and product mix costs, together with a great concern on processes – high service levels, optimal scheduling policies, setup times and costs, etc. Nowadays, the rapid technological progress and the associated competitive problems lead to a great need of fast and successful solutions to deal with continuous change (re-design) of the currently used industrial systems. Flexibility, modularity, efficiency and robustness are generally highly desired system properties. For general design of industrial systems, three basic types of software tools are used: Computer Aided Design, Simulation and Information Systems. These tools help on improving the utilization of system resources like equipment, manpower, materials, space, energy, information, etc. Nevertheless these three types of software tools have been used with low levels of integration. This absence of an adequate data connection and integration of outputs cause time delays in the design process...

Automation of government financial management (GFM) systems is one of the core elements of the reform program since ready availability of timely and accurate information is critical to the management of government finances and public funds; and it may simply not be possible to obtain the information required for economic management in a timely manner without some degree of automation, in view of the large transaction volumes involved and their dispersal across multiple sites around the country. These systems are also referred to as integrated financial management information systems (IFMIS). As described in this handbook, IFMIS consists of a number of modules which support the different functional processes associated with GFM. These include modules for macroeconomic forecasting, budget preparation, budget execution (including cash management, accounting, and fiscal reporting), managing the size of the civil service establishment and its payroll and pensions, debt management, tax administration, and auditing. This handbook tries to fulfill the need and to provide information related to the entire systems life cycle...

Mestrado em Informática e Gestão; With the growing, pervasive use of information systems (IS) by most organizations, particularly companies in technology-intensive businesses such as banking, questions arise as to the effective success of those systems, how to measure it and, most of all, what influences it. User satisfaction, even if not an end goal of IS organizations, is frequently used as a measure of that success and it has been empirically shown to correlate with other more direct measures. Several research lines, then, look at what influences user satisfaction, particularly what characteristics of information systems and their development processes tend to result in higher user satisfaction. The research reported here looks at the specific case study of a Portuguese bank, for which a comprehensive survey is undertaken yearly to record the satisfaction of its thousands of IS users’ regarding its numerous information systems. Additional primary data was collected to characterize the information systems and their development processes, which, once structured and standardized alongside the user satisfaction survey results provided the basis for a quantitative analysis of the relationships between IS success, measured by user satisfaction...

peer-reviewed; This paper reports the findings of a detailed study of Web-based systems design (WBSD) practices in Ireland based on data collected over a 3-year period (2002–2005), the objectives of which were to (1) contribute towards a richer understanding of the current “real-world” context of WBSD by characterising the profile of a typical project (team size, timeframe, nature of requirements, etc.) and identifying the key challenges, constraints, and imperatives (i.e. “mediating factors”) faced by Web-based system designers, and (2) understand how those contextual parameters and mediating factors influence the activity of WBSD as regards the selection and enactment of whatever design practices are therefore engaged (i.e. the use of methods, procedures, etc.). Data was gathered through a survey which yielded 165 usable responses, and later through a series of semi-structured qualitative interviews. Using grounded theory, an explanatory conceptual framework is derived, based on an extension of the “method-in-action” model, the application of which to WBSD has not been previously investigated in depth. It is proposed that this framework of WBSD issues is valuable in a number of ways to educators, researchers, practitioners...

An Information Systems Design Theory (ISDT) is a prescriptive theory that offers theory-based principles that can guide practitioners in the design of effective Information Systems and set an agenda for on-going research. This paper introduces the origins of the ISDT concept and describes one ISDT for Web-based Education (WBE). The paper shows how this ISDT has, over the last seven years, produced a WBE Information System that is more inclusive, flexible and is more closely integrated with the needs of its host organization.
