Manufacturability Evaluation

In the light of growing global competition, organizations around the world today are constantly under pressure to produce high-quality products at an economical price. The integration of design and manufacturing activities into one common engineering effort has been recognized as a key strategy for survival and growth. Design for manufacturability (DFM) requires product designers to simultaneously consider the manufacturing issues of a product along with the geometrical and design aspects. In this paper, part manufacturability was analyzed in detail. An evaluation system of DFM was proposed. Product design can be guided according to feedback information by evaluating the part manufacturability.

Manufacturability Evaluation

In the light of growing global competition, organizations around the world today are constantly under pressure to produce high-quality products at an economical price. The integration of design and manufacturing activities into one common engineering effort has been recognized as a key strategy for survival and growth. Design for manufacturability (DFM) is an approach to design that fosters the simultaneous involvement of product design and process design. The implementation of the DFM approach requires the collaboration of both the design and manufacturing functions within an organization. At present, For some reasons DFM approach is ineffectively including lack of interdisciplinary expertise of designers; inflexibility in organizational structure, which hinders interaction between design and manufacturing functions. Design for manufacture is the practice of designing products with manufacturing in mind. Early consideration of manufacturing issues can shorten product development cycle time, minimi overall development cost and ensure a smooth transition into production. In this paper, part manufacturability under Concurrent Engineering (CE) environment was analyzed in detail. An evaluation system of DFM was proposed according to CE ideas. A fuzzy set-based manufacturability evaluation algorithm is formulated to generate relative manufacturability indices to provide product designers with a better understanding of the relative ease or difficulty of machining the features in their designs. An analytic hierarchy process (AHP) method is introduced to assign weighting factors to features to reflect their functional importance. Results from the case studies show the method available and practicable.

In the light of growing global competition, organizations around the world today are constantly under pressure to produce high-quality products at an economical price. The integration of design and manufacturing (DFM) activities into one common engineering effort has been recognized as a key strategy for survival and growth. In this paper, the importance of DFM and parts information model was introduced in today's manufacturing enterprise. It describes the classification of parts information model; namely: product models, process models and cost models, the main content and research status that the model contained. The author has proposed a semantic network description method of the manufacture parts information of and details its main content, which is the core of this paper.

AbstractIn 2019, the world celebrated the International Year of the Periodic Table of Chemical Elements (IYPT2019) and the IUPAC centenary. This happy coincidence offered a unique opportunity to reflect on the value and work that is carried out by IUPAC in a range of activities, including chemistry awareness, appreciation, and education. Although IUPAC curates the Periodic Table and oversees regular additions and changes, this icon of science belongs to the world. With this in mind, we wanted to create an opportunity for students and the general public to participate in this global celebration. The objective was to create an online global competition centered on the Periodic Table and IUPAC to raise awareness of the importance of chemistry in our daily lives, the richness of the chemical elements, and the key role of IUPAC in promoting chemistry worldwide. The Periodic Table Challenge was the result of this effort.

For a cylinder-beam integrated hydraulic press (CBIHP), the hydraulic cylinder is also functioned as an upper beam. It is the key structural component that outputs the driving force to forge parts. Compared with the traditional three-beam and four-column hydraulic press which has a cylindrical hydraulic cylinder, the structure and force distribution are significantly different for CBIHP. It is able to have higher nominal force and larger section of plunger which the pressure is applied on when the contour geometric dimension is the same. Also, CBIHP has lighter weight and larger section modulus when the nominal force is the same than the traditional hydraulic press. Finally, a 6300KN cylinder-beam integrated hydraulic press, which is the first CBIHP in the world and designed by Harbin Institute of Technology (HIT) in 2012, is also introduced in this paper. It can be seen from the results of numerical simulation for the CBIHP that both of the stresses and displacements on the press in the loading process are allowable.

Standards Development

More and more companies operate today in a worldwide market under conditions of globalization, increased complexity, and competition. In such an environment, business decisions need to be made quickly yet intelligent, substantiated by the most salient and relevant information available. Under the global competition, with a diligent and measured manner, many companies are increasingly treating business like an economic war. Enterprises are methodically monitoring and investigating their competitors, while deploying all the resources they have at their disposal in order to beat their current or future rivals. Competitive Intelligence (CI) has become the ‘latest weapon in the world war of economics’. This paper contributes to the growing body of literature on competitive intelligence by synthesizing knowledge stemming from many years of experience in the standardization arena. The authors aim to show how, in the economic war, engaging in committee-based standards development may be used for winning the competition battle.

Market Pressures

As the world moves online, various pressures drive changes in the way industries and organizations do business: market pressures, for example, global competition; technological pressures, for example, the use of e-commerce to lower the costs of production; and societal pressures, for example, government regulations (Turban, King, Lee, & Viehland, 2004). In considering the implications of the online world for industry, it is necessary to consider both structure and process, where process includes change processes (Gregor & Johnston, 2000, 2001; Johnston & Gregor, 2000). In Giddens’ (1977, 1984, 1991) theory of structuration, process (activity) and structure are reciprocal. As Giddens (1977) states, “social structures are both constituted by human agency, and yet at the same time are the very medium of this constitution”(p. 121) or, as Rose (1999) puts it, “agents in their actions constantly produce and reproduce and develop the social structures which both constrain and enable them” (p.643).

One of the challenges as well as opportunities for the success of wireless communication in the 21st century is the standardization that, in a simplified term, defines how specific technologies are used in a particular wireless communication system. Standardization goes beyond a technical decision made by engineers. This chapter first examines the history and the status of standardization in wireless communications in the world. Global cooperation and competition among different standards are then examined. Finally, the chapter analyzes ITU’s efforts on the 3G standardization that aim to bring harmony among the world’s wireless communication developers and providers.
