Estimating the optimal number of alternatives to be explored in large design spaces: A step towards incorporating decision making cost in design decision models. ABSTRACT Exploration of design spaces is an important step in decision-based design. In consumer product development, precise design specifications are not known at the beginning of the design(More)
In multiple interaction-state mechatronic devices the interactions between elements of use-environment and elements of the device can have different qualitative structures depending upon the modes of the device operation and the states of the use-environment. This paper describes a modeling framework to support conceptual design of such devices using state(More)
During the cyber security construction process, how to set proper security standard and investment quota in accordance with the important degree of its information is a universal problem of enterprises. We propose a dynamic Invest-Attack Model based on Information Asymmetry between the protectors and attackers of cyber security and make RD analysis to the(More)
Based on the analysis of two current representative modes of financial subsidy to agricultural water by introducing the theory of economics, this paper, set up an incentive model of water-saving in the premise of financial subsidy, in order to explore a financial subsidy mode on agricultural water and agriculture water price mechanism suitable for present(More)
Technological innovations provide an opportunity to improve product performance and reduce cost. Therefore, design organizations are interested in monitoring technological innovations. A large number of innovations are announced every year. Monitoring them manually is very time consuming. We are developing web-based innovation-alert services that can be(More)
Increasingly, complex mechatronic systems are being designed to have higher levels of autonomy and intelligence. This requires them to operate in multiple interaction-states. To facilitate computer-aided conceptual design of complex mechatronic systems, this paper provides a framework for modeling design concepts behind mechatronic systems with multiple(More)
To solve many issues that exist in supply chain management in publishing enterprises in China, combined with an innovative mode case for Tsinghua University Press, this article has proposed a strategy named as integration of branch press platform and distributor. Several comparisons between and analysis of the new strategic mode and outdated supply chain(More)
This paper analyses the effect of network infrastructure imposed on economic growth in China. It also analyses the relationship between network infrastructure and economic growth. And the role Chinese network infrastructure play in economic growth course is discussed in this paper with modified secondary CES Production Function with three factors. Data from(More)
An assessment indictor system for management of urban wetland is established in this paper, based on the Research - Restoration - Recreation framework, which can denote the relationships between the ecological functions and the wetland healthy state. Then with the weight of each indicator decided by analytic hierarchy process, a fuzzy pattern recognition(More)
In order to reduce product development time, we need software tools that can perform automated validation of the proposed design concepts. These tools will ensure that only valid design concepts are transferred to the detailed design stage for further development. This paper provides a step towards the automated validation of proposed design concepts. We(More)
