For rapid product developments in today′s competitive global marketplace, we need tools to facilitate the effective utilization of critical design and manufacturing knowledge obtained during the previous product developments. The Internet technology has very rapidly evolved over past few years. The web is being increasingly used to support various activities of the pro duct development process. Java is a programming language that is highly tuned for the web environment. This paper is concerned with providing the solution of web based manufacturing process development. The architecture of web based application and the implementation of web based manufacturing process developer are discussed.展开更多

Adopting knowledge based engineering to reuse and manage product design knowledge, and combining feature modeling and parametric design based on existing CAD/CAE/CAM system and technology of product family modeling and engineering database, the system establishes a product family knowledge base, which mainly including product family case base and rule base. The system also utilizes WEB technology to let customers to individually customize products remotely through internet. And an applicable example is given in the end.展开更多

To building up such a system, we must follow certain working procedures which usually consist of four steps: to determine the performance objectives, to design the structure of indicator system, to specify the indicators and to set up the weight of indicators. Each step plays a different role in performance evaluation indicator system and has its own impact on the realization of performance evaluation objectives respectively. So the scientifically building up a performance evaluation indicator system is the key to determine whether the intellectual property is protected well or not.展开更多

This is targeted seriously towards firms acquiring Knowledge Systems (KS) in order to nurture the employees' capabilities. Therefore, to enhance performances and their highly creative direction takes consideration of QE (quality engineering) and KS and disciplines complementary to each other. Additionally, the flow of operations and activities of the KS through the application of quality engineering (QE) principles is according to the view of Japanese engineer Taguchi. This aims to achieve good quality in the product design and processes, and also to anticipate problems that may occur before the shipping of the products. In this study, the use of quality control engineering and Taguchi's function methods in determining these properties and the loss caused by the company will be examined. However, the adopted approach of study scope to the society will aid KS. Also, efforts in this direction motivate the employment of a statistical method by Taguchi which relied on the principle of target-oriented quality, representing the value characterising the product quality.展开更多

On-farm trials in phosphate-deficient soils in Western Kenya demonstrated MPR to be as effective as triple superphosphate (TSP) - 20% P, at equal P rates. The aim of this work is to determine the distribution of phosphorus in these phosphate rocks (PRs). The different phosphorus fractions were extracted using the modified Williams extraction procedure and analysis carried on a UV/VIS spectrometer (SHIMADZU UV-220-02 and NOVASPEC II). The analysis showed that the most abundant form of phosphorus in the phosphate rocks was the Inorganic Phosphorus (IP) contributing 74.20% of total phosphorus (TP) for Minjingu, and 83,28% of total phosphorus for Ikutha phosphate rock.展开更多

It is the key phase to ensure that the functional requirement of the design product can be appropriately complied with, and its result is also the rudiment of the subsequent detailed design work. If this important phase can be supported by an increasingly distributed resource environment, and be automated such that its completion requires less manual work, the efficiency of the design process would be largely improved and its ability to promote innovation would be enhanced. Therefore, this study involved a detailed analysis of the functional knowledge integration of the design process, as well as the proposal of a corresponding running model. Based on the model, a computational algorithm and an evaluating method were established to automate functional knowledge integration. A corresponding computer program was developed to prove the feasibility of this approach, and it was used to design a solarpowered wiper blade.展开更多
