T1 - Knowledge Elicitation through a Pragmatic Inquiry N2 - This is a paper about knowledge in design and how to elicit knowledge from design processes. The paper is a preparation for an empirical study of interaction in the design process. Reasonings of three authors - Schön, Broadbent and Lundequist - on design processes is presented. They all have a pragmatic perspective in common, and regard the process as an activity without a definite form. Design is seen as an activity of creating models of forms and shapes, by addressing expert knowledge ­ in a dialogic way ­ to problematic situations. Due to the pragmatic approach I find the pragmatist Dewey´s understanding of knowledge and elecitation of knowledge appropiate for studying design processes. According to him it is possible to build up objectified descriptions of experiences, also of such, which are based on experiences of emotional and intuitive nature. There need not be a definite border, which separates tacit knowledge from explicit knowledge - when it comes to the question of the possibility of verbal descriptions. Tacit knowledge is possible to articulate within pragmatic thinking. The conclusion is, that it is possible to study the tacit knowledge of design processes, and get some qualitative insights useful for theory building. A study of design processes can look at three different forms of knowledge. It appears as a pre­cognitive understanding of the design situation, as integrated in the design activity - seeing the situation as something known - and in the process of creating something new.

Its field of application comprises buildings constructions, structures and also parts and components for the residential, commercial and un-inhabitant structures with invariability of physical and geometrical parameters in some dimensions. We should mention here in particular such objects as beams, thin-walled bars, strip foundations, plates, shells, deep beams, high-rise buildings, extensional buildings, pipelines, rails, dams and others. DCBEM comes under group of semianalytical methods. Semianalytical formulations are contemporary mathematical models which currently becoming available for realization due to substantial speed-up of computer productivity. DCBEM is based on the theory of the pseudodifferential boundary equations. Corresponding pseudodifferential operators are discretely approximated using Fourier analysis or wavelet analysis. The main DCBEM advantages against the other methods of the numerical analysis is a double reduction in dimension of the problem (discrete numerical division applied not to the full region of the interest but only to the boundary of the region cross section, as a matter of fact one is solving an one-dimensional problem with the finite step on the boundary area of the region), one has opportunities to carrying out very detailed analysis of the specific chosen zones, simplified initial data preparation, simplistic and adaptive algorithms. There are two methods to define and conduct DCBEM analysis developed – indirect (IDCBEM) and direct (DDCBEM), thus indirect like in boundary element method (BEM) applied and used little bit more than direct.

A1 - Akimov, Pavel T1 - Discrete-continual Finite Element Method of Analysis for Three-dimensional Curvilinear Structures N2 - This paper is devoted to discrete-continual finite element method (DCFEM) of analysis for three-dimensional curvilinear structures. Operational and variational formulations of the problem in the ring coordinate system are presented. The discrete-continual design model for structures with constant physical and geometrical parameters in longitudinal direction is offered on the basis of so-called curvilinear discrete-continual finite elements. Element coordinate system, approximation of nodal unknowns, construction of element nodal load vector are under consideration. Element system of differential equations is formulated with use of special generalized block-structured stiffness matrix of discrete-continual finite element. Local differential relations are formulated. Resultant multipoint boundary problem for system of ordinary differential equations is given. Method of analytical solution of multipoint boundary problems in structural analysis is offered as well. Its major peculiarities include universality, computer-oriented algorithm involving theory of distributions, computational stability, optimal conditionality of resultant systems, partial Jordan decomposition of matrix of coefficients, eliminating necessity of calculation of root vectors. Brief information concerning developed software is provided.

T1 - Models generation : from urban simulation to virtual reality N2 - The aim of researches conducted within gamsau about urban simulation, in particular Remus project, is to allow rapid modeling of large and regular urban zones, for purpose of interactive navigation (like VRML) or for realistic rendering (ray-tracing methods). One of problems to be solved in this context is the multiplicity of data formats : inputs come from different sources, and outputs are for heterogeneous systems of visualization. Typically CSG and boundary representation must be generated, treated and converted during building of models. Furthermore, the generated models can be more or less refined, depending on requests and type of use. This paper describes the general context of data models conversion, problems concerning levels of detail and implementation done in Remus, based on object oriented approach.

The resource allocation problem consists in assigning time intervals to the execution of the project activities while taking into account temporal constraints between activities emanating from technological or organizational requirements and costs incurred by the resource allocation. If the total procurement cost of the different renewable resources has to be minimized we speak of a resource investment problem. If the cost depends on the smoothness of the resource utilization over time the underlying problem is called a resource levelling problem. In this paper we consider a new tree-based enumeration method for solving resource investment and resource levelling problems exploiting some fundamental properties of spanning trees. The enumeration scheme is embedded in a branch-and-bound procedure using a workload-based lower bound and a depth first search. Preliminary computational results show that the proposed procedure is promising for instances with up to 30 activities.

Den laufenden Auszahlungen für Löhne, Materialien und fremdbezogene Dienstleistungen stehen dabei erst nach einiger Zeit Fortschrittszahlungen für abgeschlossene Teilprojekte gegenüber. Die Durchführung eines solchen Projekts kann mithin als Investition angesehen werden. Im Gegensatz zu herkömmlichen Investitionen liegen bei Investitionsprojekten die Zeitpunkte der Ein- und Auszahlungen nicht fest, sondern sind Gegenstand der Planung. Zur Lösung des Annahme- bzw. Auswahlproblems bei Investitionsprojekten unter Sicherheit erfreut sich die Kapitalwertmethode breiter Zustimmung. Nach einer Betrachtung bekannter Ansätze zur Maximierung des Kapitalwerts von Investitionsprojekten unter Annahme eines vollkommenen Kapitalmarktes wird aufgezeigt, wie das vorgestellte Modell zur Kapitalwertmaximierung für den Fall beschränkt verfügbarer Ressourcen bzw. eines beschränkten Kreditrahmens angepasst werden kann. Die Bewertung von Investitionsprojekten auf Grundlage des optimalen Projektkapitalwerts setzt die Kenntnis des anzuwendenden Kalkulationszinsfußes und der maximalen Projektdauer voraus. Da diese Größen a priori nicht bekannt sind, entwickeln wir ein Verfahren zur Bestimmung des Kapitalwerts von Investitionsprojekten als Funktion des Kalkulationszinsfußes und der maximalen Projektdauer. Abschließend zeigen wir, wie die erzielten Resultate zur Entscheidungsunterstützung eines Bauunternehmers genutzt werden können.
