An integrated engineering environment is described wherein capabilities are provided for addressing the role of human operators and decision makers in complex systems. The manner in which the environment supports the implementation of a human engineering process as an integral part of a standard systems engineering process is described. The capabilities of a prototype Human Centered Design Environment currently under development are discussed.
An integrated engineering environment is described wherein multidisciplinary capabilities are provided for addressing the role of humans in complex systems. The integration of these capabilities is based on the implementation of a common system design repository in a client-server architecture. The approach is based on the definition of an integrated process to support the engineering of large, complex systems which include humans as operators and decision makers. Such a process is by necessity multidisciplinary in that diverse specialties are required in order to achieve a well-balanced design. The implementation and execution of the process requires a collaborative approach across the various disciplines in order to define desired human roles in the system and to trade off between human and non-human implementation of system functionality. To enable the collaborative process and to manage the complexity of the evolving design, an integrated design environment is defined. The capabilities ofthe integrated environment support both system level and human engineering level design activities.A system data base schema is also defined to enable the implementation of a common design repository for integrated product and process management and to assure interoperabiity of the associated tools within the environment.
This paper will introduce the development of an information representation schema that can be used to support the development of complex human centric systems. Technology that was adopted to support schema evolution to accommodate new methods and tools or schema tailoring for the need of a specific program will also be addressed.
The complexity and sheer magnitude of modern computer based systems require a structured approach for their development. The principal objective of system development is to establish a design which satisfies the system requirements while optimizing the key trade‐offs associated with system functionality, behavior, and implementation. A methodology is presented in this paper for a multi‐domain system design capture approach. The methodology employs five views of the system which address the system design in separate but related domains. The basis for creating an integrated, automated environment for addressing design, capture and analysis of a complex system is discussed by: (1) defining each of the five views and organizing those views into three models of the system, (2) defining the relationships and dependencies between the models of a given system, and (3) identifying opportunities for application of advanced modeling and decision support techniques in the design, capture, and analysis of complex systems.
Abstract. The collection and management of data associated with the design and development of large complex systems is a critical activity supporting the systems engineering process. This paper describes the top level requirements for an advanced data repository supporting systems engineering activities in the development of large, complex, computer-based systems. The repository requirements are addressed in three categories: repository functional requirements, non-functional requirements (e.g., performance, dependability, scalability), and implementation standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
