This study presents a robust design method for autonomous photovoltaic （PV）-wind hybrid power systems to obtain an optimum system configuration insensitive to design variable variations. This issue has been formulated as a constraint multi-objective optimization problem, which is solved by a multi-objective genetic algorithm, NSGA-II. Monte Carlo Simulation （MCS） method, combined with Latin Hypercube Sampling （LHS）, is applied to evaluate the stochastic system performance. The potential of the proposed method has been demonstrated by a conceptual system design. A comparative study between the proposed robust method and the deterministic method presented in literature has been conducted, The results indicate that the proposed method can find a large mount of Pareto optimal system configurations with better compromising performance than the deterministic method. The trade-off information may be derived by a systematical comparison of these configurations, The proposed robust design method should be useful for hybrid power systems that require both optimality and robustness. 相似文献

The article addresses the general educational concepts of engineering design together with the contrast of current instruction techniques in tertiary institutions. Work at Melbourne is reviewed in this context with particular reference to matching educational objectives to current educational theory. A case study in engineering design is evaluated against this frame of reference and some educational hypotheses are proposed. It is concluded that testing of the proposed hypotheses will require considerable research effort by design educators. 相似文献

The notion of design thinking is becoming more concrete nowadays, as design researchers and practitioners study the thinking processes involved in design and employ the concept of design thinking to foster better solutions to complex and ill‐defined problems. The goal of the present research is to develop a cognitive activity‐based design methodology for novice visual communication designers, which will be achieved by mapping the findings from a comparative analysis of novice and expert visual communication designers' thinking processes onto the prospective methodology. Under the proposed methodology, activity modes take place in a chronological flow under specific guidelines involving various forms of design cognition. The guidelines correlate to design phases from problem structuring to detailed design and to the cognitive processes of divergent and convergent thinking. The methodology gives open‐ended instruction to novices endeavouring to proceed with the design process, solve complex design problems and make better design decisions. This research has value for its unique approach to methodology development. Furthermore, the proposed methodology provides guidance for more effective cognitive activities during the design process and holds potential for implementation in design education due to its focus on the needs of novice designers. 相似文献

As an important element in sustainable building design, the building envelope has been witnessing a constant shift in the design approach. Integrating multi-objective optimization (MOO) into the building envelope design process is very promising, but not easy to realize in an actual project due to several factors, including the complexity of optimization model construction, lack of a dynamic-visualization capacity in the simulation tools and consideration of how to match the optimization with the actual design process. To overcome these difficulties, this study constructed an integrated building envelope design process (IBEDP) based on parametric modelling, which was implemented using Grasshopper platform and interfaces to control the simulation software and optimization algorithm. A railway station was selected as a case study for applying the proposed IBEDP, which also utilized a grid-based variable design approach to achieve flexible optimum fenestrations. To facilitate the stepwise design process, a novel strategy was proposed with a two-step optimization, which optimized various categories of variables separately. Compared with a one-step optimization, though the proposed strategy performed poorly in the diversity of solutions, the quantitative assessment of the qualities of Pareto-optimum solution sets illustrates that it is superior. 相似文献

In order to enhance the reliability of an uncertain structure with interval parameters and reduce its chance of function failure under potentially critical conditions, an interval reliability-based design optimization model is constructed. With the introduction of a unified formula for efficiently computing interval reliability, a new concept of the degree of interval reliability violation (DIRV) and the DIRV-based preferential guidelines are put forward for the direct ranking of various design vectors. A direct interval optimization algorithm integrating a nested genetic algorithm (GA) and the Kriging technique is proposed for solving the interval reliability-based design model, which avoids the complicated model transformation process in indirect ones and yields an interval solution that provides more insights into the optimization problem. The effectiveness of the proposed algorithm is demonstrated by a numeric example. Finally, the proposed direct reliability-based design optimization method is applied to the optimization of a press upper beam with interval uncertain parameters, the results of which demonstrate its feasibility and effectiveness in engineering. 相似文献

Recently, there has been an increased interest in producing electronic courses. However, literature shows that adopting e-learning
does not guarantee improved learning. This is because mixing technology and content does not necessarily yield effective learning.
This paper presents a systematic design process for developing blended courses for undergraduate higher education. The instructional
design process is based on instructional design theories and utilized three taxonomies: Bloom Taxonomy, Redeker Taxonomy and
Guerra scale. A mapping model is proposed and embedded in the design process to develop a blended course starting from the
objectives and content of a traditional course. This paper also presents a evaluation process that estimates the effectiveness
of the selected technologies in the design of the blended course. This effectiveness is evaluated in terms of three dimensions:
course content formats, interaction and collaboration. A case study is presented to demonstrate the proposed design approach
on a System Analysis and Design blended course under development. 相似文献
