Abstract The expectations of computer tools to support the conceptual design phase are not yet met. An experimental approach to discover the use of information in conceptual design will give a realistic insight of the information requirements. This can be used to specify future computer support systems. A method to observe the use of information in a conceptual design process has recently been developed. The method has been tested and fine-tuned through the observation of 10 design sessions. Valuable empirical data resides from this experiment. Data has been analyzed in several perspectives. This paper presents the results of the activity/information analysis of the experiment in relation with the quality of the design concept. For the latter a rating system has been defined to quantify this. We have found a significant positive correlation of the amount of information that is communicated and the quality of the design. Furthermore a discussion is given on the relation between information and the activities of the designer. Analysis activities are more communication intensive compared to synthesis and evaluation tasks.

Abstract Conceptual design is the initial stage of the transformation between functional and structural descriptions of devices. Our primary aim is to develop ideas that will allow computer tools for conceptual design to be built. In this paper, we point out a fundamental trade-off between the expressiveness of design languages and the computational complexity of the resulting design problem. Research in computational conceptual design can therefore be viewed as the problem of defining a design language and then devising ways of controlling the size of the resulting design space. We propose that an effective means of controlling complexity is to use knowledge of existing designs to guide the synthesis of novel designs. We illustrate this concept with a program that designs novel mechanical fasteners from knowledge of existing fasteners. We analyze this experiment and highlight several areas for future work.

Aerodynamic Configuration

Aircraft are great and comprehensive technical systems, which are characterised by the great configuration density. This article presents formation of the geometrical conceptual design of the aircraft on the basis of the formal heuristic procedures within the framework of the infrastructural constraints. In addition, this article includes description of influence of the aerodynamic configuration and the volume-weight configuration upon formation of the geometrical conceptual design of the aircraft, as well as description of other mass/inertia characteristics of the aggregates, which are to be installed within the specific aircraft. This article also states that in the case of the "very strict" infrastructural constraints, it is necessary to solve "the inverse" problem of configuration, that is the problem, where initial data for formation of the geometrical conceptual design of the aircraft are determined by the necessary configuration space, which is determined by the infrastructural constraints. The article presents the project problem (in aggregate) of finding rational values for parameters of the geometrical conceptual design of the aircraft as the problem of the multiple criteria discrete optimisation. This article states that it is possible to formulate this problem as the search of the vector of structural parameters (that is, search of the multitude of the admissible alternatives of the drawing and designing solutions).

The Impact

The analysis of climate change in the Russian Federation has been carried out. It has been shown that the major climate change is occurring in the Arctic zone — increased emissions of carbon dioxide and methane, deep permafrost thawing. Due to the change of climatic conditions, improvement of the ecological situation and wide use of biological cleaning systems for a treatment of industrial and household effluents a change of biological systems is taking place. Natural selection of microorganisms capable to use as a nutritious substratum such previously inert materials as polyethylene and polypropylene is intensified. The change of climatic conditions in which complex technical systems are operated, and the impact of biological and ecological factors on these systems dictate the need for revision of approaches to creation, design and operation of appropriate technical means. Actions for standardization of procedure for products climatic qualification taking into account the influence of newly forming climatic, ecological and biological conditions will allow considerably reduce economic losses from corrosion, aging and biodeterioration of complex technical systems. The work has been carried out in the frame of implementation of complex research area 18 “Climatic Tests for Safety Provision and Protection from Corrosion, Aging and Biodeterioration of Materials, Constructions and Complex Technical System in Natural Environments” (“Strategic Areas for Development of Materials and Their Treatment Technologies for the Period until 2030”).

Abstract Gilead et al. offer a thoughtful and much-needed treatment of abstraction. However, it fails to build on an extensive literature on abstraction, representational diversity, neurocognition, and psychopathology that provides important constraints and alternative evidence-based conceptions. We draw on conceptions in software engineering, socio-technical systems engineering, and a neurocognitive theory with abstract representations of gist at its core, fuzzy-trace theory.
