Experiences in assisted mobility: the SIAMO project

Abstract: This paper presents the results and experiences from the SIAMO project, a work carried out by the assisted mobility group of the Electronics Department of the University of Alcala, in Spain. The main objectives of the project are the design and testing of modular electronics systems fitted to a suitable architecture that can deal with the different needs of potential users. Modularity is one of the advantages of the designed architecture: a standard serial bus is used to link different modules that can be installed or removed easily and quickly over a unique standard basic platform. Action lines of the SIAMO team include: human-machine interfaces, design and testing of new driving and commanding modes, sensory systems to improve safety and navigational skills, and control architectures to implement autonomous navigation with a minimum cost on both the building and wheelchair.

An aggregate model of project-oriented production

Abstract: A production system is studied in which thousands of activities are carried out concurrently subject to precedence constraints and limitations on resources such as skilled labor and equipment. Ideally, management proposes a set of milestone dates, obtains an analysis of which milestones cannot be met, and determines which resources are underused or overused. This process continues interactively until milestones consistent with management's objectives are obtained. The authors derive, from elementary principles and basic assumptions (axioms), a continuous-time model of project execution of an aggregate level of detail. The model is approximated using a set of linear inequalities. This data structure can be manipulated easily and quickly by methods of linear programming to perform the required analysis. >

Economic impact dynamics of complex engineering project scheduling

Abstract: The authors show how scheduling of complex multiprocess manufacturing or construction operations can be examined in an interindustry framework for its impact dynamics on a national or regional economy The technical coefficients of the static Leontief input-output model are replaced by time-phased input coefficients containing additional information on the timing of industry inputs with respect to product completion Coupling engineering project scheduling methods, such as the critical path method (CPM), to SIM (sequential interindustry model) allows the investigation of two distinct engineering-economic issues The first involves the development of the time-phased input coefficients themselves The second involves computation, by SIM, of the dynamic economic impact of large, complex, and lengthy production, construction, and related macroengineering undertakings The resulting total economic impact chronology is determined by the interaction of payment schedules with the regional and national economies, consisting of industries that are themselves described through time-phased input coefficients >

Strategic R&D program selection and resource allocation with a decision support system application

Abstract: Continuous evaluation of engineering project ideas for portfolio selection and resource allocation is one of the most challenging decisions that managers make on an ongoing basis. Decisions regarding project portfolios must be continuously monitored and updated due to the emergence of new opportunities and availability of more profitable projects, changes in the technical and/or commercial success probabilities, possible changes in the organizational objectives and goals, and variations in the forecasts at different points in time as the development and implementation of optimal decision rules take place. This paper presents a decision support system to assist management in systematically allocating resources to competing interrelated R&D projects under uncertainty within semi-structured decision environments. The model and the decision process integrate and extend the attractive features of scoring techniques, pairwise comparison method and probabilistic tradeoff development method. >

Concurrent engineering: The DARPA initiative: encouraging new industrial practices

Abstract: The DARPA Initiative in Concurrent Engineering (DICE), is a program launched in 1988 by the US Dept. of Defense's Defense Advanced Research Projects Agency (DARPA) to encourage the practice of concurrent engineering in the US military and industrial base. The overall goal is to develop an architecture for concurrent engineering in which the people working on a project can instantly communicate with each other and access, share, and store up-to-date information in a transient way, unhindered by geographic separation, organizational structure, product complexity, or incompatible tools, databases, and computing resources. The concurrent engineering services are being developed in conjunction with several pilot projects. All the project members belong to 'tiger teams', interdisciplinary groups that rove across traditional department boundaries, communicating their insights, making recommendations, and negotiating conflicts. >
