A mailed-questionnaire survey was used to examine 23 questions about LPD principles and practices. The target population for the study was Brazil＇s largest product development and design companies. The study identified that although the automobile sector is seen as a reference in the adoption of lean practices, there is still potential for improvement by establishing partnership relations with suppliers, and with those on the other points of the chain by identifying what provides value to clients. Set-based concurrent engineering is also a practice that needs to be better developed, as well as the value stream mapping tool to identify waste and activities that add value to the product development process. There has been no previous study of this nature in Brazil that characterizes the sector and highlights its importance in relation to the global scene, providing incentives to international investors. The value of the work is in the results that allow diagnosing the lean development practices that are most used in the automotive sector. Moreover, the survey questions can be applied in other economic sectors and at companies of other sizes. The study contributed to providing a systematic view of the product development process from the perspective of people, processes, and technology, and assists companies and academics manage change.展开更多

China faces unprecedented opportunities for development, although there are many challenges it must face, It has become a strategic choice for all automotive enterprises to implement supply chain management in order to achieve competitive advantages. At present, most researches on supply chain partnerships have been carried out based on enterprises in developed countries. Very few theoretical and empirical studies have been based on developing countries, and in particular, only a few scholars have examined supply chain partnerships in China. Based on the joint ventures, this paper is a review of partner theories and process of partner relationship. With respect to the supply chain partnership strategy and process and partners＇ capability literature, there is limited research on the special background such as joint ventures or Chinese automotive industry. Some literature on partners＇ capabilities is based in favor of the operational aspects.展开更多

The conspicuous results of alloy optimization with thermodynamic simulations for semisolid processing of commercial AM60 alloy were present. The results indicate that the available processing temperature range of AM60 alloy is 170 ℃. The temperature sensitivity of solid fraction decreases with increasing solid fraction or with decreasing temperature above eutectic reaction temperature of AM60 alloy. When the solid fraction φs is 0.4, corresponding processing temperature is 603.8 ℃ and the sensitivity -dφs/dT is 0.0184. The effects of various alloying elements on the solidification behavior and SSM processability of AM60 alloy were calculated with Pandat software.展开更多

It was identified the need to redesign the regulation sieve system harvester, which is a compound assembly in the harvester＇s grain cleaning system, with the objective to reduce the costs and improve the ergonomic aspect, keeping the same efficiency from the original project. The improvement was developed by studying the original design and identifying possible project fails, such as components and manufacturing process which could be eliminated. For this, it was needed to do a research about rules and project considerations that must be applied in the products development and ergonomic too, specifically about geometric forms and anthropometric measures. From the redesign of this system, it is verified that it is possible by a study to identify possible improvements, and to develop a new system by a simple project, improving the ergonomic, reducing the cost and keeping the same efficacy from the original project.展开更多

Therefore, a new multilateral model of cross-industry alliance needs to arise. The advanced charging technology of Internetdistributed mobile energy can link up with many market participants closely and form an effective and multilateral win-win cross-industry alliance. This new industry alliance can realize unexpected multiple goals, for example,(1)consumers who have purchased new energy vehicles can avail free charging;(2) potential vehicle buyers can be encouraged to use new energy vehicles;(3) the new energy vehicle manufacturers can expand their production scale;(4) the new energy vehicles sellers(4 S shop) can expand their sales volume;(5) large shopping malls can attain more income;(6) financial institutions can absorb more deposits;(7) governments can further promote low-carbon traffic. This article analyzes the cross-industry alliance and its forming mechanism.1)展开更多
