Ontological reasoning in the design space exploration of advanced cyber–physical systems

Cyber–physical systems are becoming increasingly complex. In these advanced systems, the different engineering domains involved in the design process become more and more intertwined. Therefore, a traditional (sequential) design process becomes inefficient in finding good design options. Instead, an integrated approach is needed where parameters in multiple different engineering domains can be chosen, evaluated, and optimized to achieve a good overall solution. However, in such an approach, the combined design space becomes vast. As such, methods are needed to mitigate this problem.In this paper, we show a method for systematically capturing and updating domain knowledge in the context of a co-design process involving different engineering domains, i.e. control and embedded. We rely on ontologies to reason about the relationships between parameters in the different domains. This allows us to derive a stepwise design space exploration workflow where this domain knowledge is used to quickly reduce the design space to a subset of likely good candidates. We illustrate our approach by applying it to the design space exploration process for an advanced electric motor control system and its deployment on embedded hardware.     

中置式高压电容器柜改进设计

分析了南屯煤矿白马河风井变电所高压电容器柜原设计方案存在的问题,并对其进行了改进设计:选用适用于容性负载的真空断路器;添加放电线圈,并将放电线圈与电容器直接并联,使放电线圈与电容器组成一个完整的放电回路;添加接地开关,接地开关既有机械闭锁又有电气联锁,操作方便,安全性高。实际应用表明,改进设计后的高压电容器柜功能更加完善,更加安全、可靠。     

“恋衣狂”张爱玲的服装设计艺术

张爱玲是现代中国自称为"恋衣狂"的仙才作家。她不仅是我国服装文化的研究者,也是身体力行的实践者。她中西交融、化俗为雅、参差对照、猎求奇异和贵族化情结的服装设计艺术,与她的小说《传奇》一样,已成为人们永远讲不完的神话故事。     

Model-guided evaluation of consumer products

An evaluation of a consumer product is presented as an example of how ergonomics models can guide data collection and interpretation by non-ergonomists. The product, a new cooking pan, was compared with its earlier counterpart on performance and safety tests for specific features. Model-guided evaluations produced data which could be well-fitted by linear relationships, and measures derived from the data could be interpreted in physical terms by engineers. This is now the standard methodology for pan evaluation in the client company.

Defining Specifications for Custom Products: A Multi-Attribute Negotiation Approach

Defining product specifications so that customers' needs could be well matched with suppliers' capabilities is a very challenging task in custom product design. This research links technical requirements on product design with product management issues and formulates specification definition as multi-attribute negotiation. Specification negotiation is modeled as an iterative process of give and take in search of a mutually acceptable configuration. A negotiation support system is developed based on a product configuration system to identify among the multiple attributes what to give, what to take, and by how much so as to facilitate specification negotiation operationally.     

Controlling the Cold Roll Forming Design Process

The cold roll forming process requires successive forming profiles to be determined and an appropriate number of profiled roll sets to be designed for the product to be rolled. This paper examines the design process and how one company has put in place a design-production control system that allows designs to be ranked in terms of quality and efficiency. In addition, consideration is given to the proportion of time given to each design task and how non-creative design activities can be automated.
