the automobile industry’s wastewater not only contains high levels of suspended and total solids such as oil, grease, dyestuff, chromium, phosphate in washing products, and coloring, at various stages of chassis manufacturing but also, a significant amount of dissolved organics,resulting in high bod or cod loads. suspended solids can be removed from the wastewater by chemical precipitation. h...

the development of a number of different rapid prototyping (rp) technologies with wide-ranging capabilities, features and applications has created the problem of selecting an appropriate rp system for engineering educational institutions as well as manufacturing organizations intending to adopt this new technology. this paper presents an rp decision support system (rp dss) for ranking and selec...

Count data sometimes exhibit a greater proportion of zero counts than is consistent with the data having been generated by a simple Poisson or negative binomial process. For example, a preponderance of zero counts have been observed in data that record the number of automobile accidents per driver, the number of criminal acts per person, the number of derogatory credit reports per person, the n...

We propose a nonparametric model for global cost minimization as a framework for optimal allocation of a firm’s output target across multiple locations, taking account of differences in input prices and technologies across locations. This should be useful for firms planning production sites within a country and for foreign direct investment decisions by multi-national firms. Two illustrative ex...

In order to obtain a good result in the laser welding process, the laser welding technology for manufacturing an automobile body is studied in this research. The robot, the seam tracking system, and CW Nd:YAG laser are used for the laser welding robot system. Especially, the development of the laser-stripe sensor is highlighted. The laser-stripe sensor can measure the profile of the welding obj...

The pervasive computing systems inside modernday automobiles are made up of hundreds of interconnected, often replaceable components. These components are put together in a way specified by the customer during manufacturing, and can then be modified over the lifetime of the automobile, as part of maintenance or upgrading. This flexibility means that system implementers cannot know in advance wh...

A hypertext-based interactive tool supporting the management of large software libraries is presented. We claim that a simple, pragmatic approach to software reuse is best suited to aid the software engineer in solving the practical problems of software connguration from reusable components. When developing the system described in this paper emphasis has been put on the semi-automatic classiica...

The “resource-based view of the firm” has become an important conceptual framework in strategic management but has been widely criticized for lack of an empirical base. To address this deficit, we utilize a new method for identifying inter-firm differences in efficiency within the context of stochastic frontier production functions. Using data on Japanese and U.S. automobile manufacturers, we d...

The mass customization can make customized products with the mass products efficiency, which will become mainstream manufacturing mode in the 21 century. The design for mass customization is the most important factor in the mass customization, on the base of extracting the excellences of the modulization design and the variant design, the article brings forward an idea of module-based variant d...

The concept of “lean” has roots in mass production, originally in the automotive industry, and most famously, at Toyota, where Ford Motor’s original Rouge manufacturing complex was used as its benchmark. Toyota’s managers studied the text of Today and Tomorrow, a book written during 1926 by Henry Ford. Ford conceived the idea of a moving assembly line, after observing the meat packing plants in...
