Designing auction parameters for online industrial auctions is a complex problem due to highly heterogeneous items. Currently, auctioneers rely heavily on their experts in design. The ability of predicting how well an will perform prior the start comes handy auctioneers. If item expected be low-performing item, auctioneer can take certain actions influence outcome. For instance, starting sellin...

Existing large industrial control systems often exhibit poor tracking and disturbance rejection capabilities due to a large number of decentralized control loops. To improve these, a stabilizer design procedure is proposed based on H∞ optimization. The procedure is simple to apply and requires only some of the closed-loop transfer functions. Application of the approach in the Syncrude utility p...

Design using free-form developable surfaces plays an important role in the manufacturing industry. Currently most commercial systems can only support converting free-form surfaces into approximate developable surfaces. Direct design using developable surfaces by interpolating descriptive curves is much desired in industry. In this paper, by enforcing a propagation scheme and observing its nesti...

A background briefing on the use of evolutionary computation to optimise industrial designs Executive Summary Nature has a process that optimises the design of living organisms. This process is called evolution. Evolution is based on a set of key principles including the use of a genetic code and Darwinian natural selection. Todayy s scientists and engineers can use the same principles to solve...

Experimental Design (ED) is a powerful technique for understanding a process, studying the impact of potential variables or factors affecting the process and thereby providing spontaneous insight for continuous quality improvement possibilities. ED has proved to be very effective for improving the process yield, process capability, process performance and reducing process variability. However r...

Design must be understood as a word that describes both a process and an outcome. It is the process of turning ideas into material things. The word design can be used with legitimacy in many activities, the design of a sales or financial plan, the design of a new organisation, or the design of a home construction project like building shelves. Many individuals have followed a design process in ...

The chemical process industry aims particularly at energy, capital expenditure and variable feedstock cost savings due to fierce global competition, the Kyoto Protocol and requirements for sustainable development. Increasingly conceptual process design methods are used in the industry to achieve these aims. They are used in: • existing processes to renew parts; • process re-designs based on exi...
