The perceived impact of supply chain management on organizational effectiveness and quality

2010-10-06
2010-36-0173
Few products or services exist that do not require some supply chain management. The more suppliers that are involved the more complex the supply chain management becomes. Even if the entire supply chain from basic raw materials that come from the earth or out of the minds and actions of people, is not considered there is still a supply chain that must be attended and in today's global economy competition is growing every day, and automotive products (vehicles and components) are often developed in one country though it's made based on global architectures, used and applied in other markets, and to find success in this competitive reality, automakers and/or global business migrated from local suppliers to global sourcing and in today's world of global outsourcing, supply chain management plays an ever important, strategic and expanding role in delivering results once automakers are aiming to launch low cost vehicles and recognized as world best-in-class products.

The purpose of this study is to establish the criteria of election of an electrical architecture tailor-made for the emerging markets, to be applied during the whole vehicle's lifecycle. A literature review about related subjects as the meaning of "electrical architecture," its techniques, criteria and methodologies of development, and the definitions of emerging and developed markets is also presented. Based on the bibliographical research, documentary analysis and unstructured interviews with active members of the automotive industry, the criteria for election of electrical architectures for emerging markets was established, as well as their describers and swing-weights, required by the use of the additive aggregation method - a multi-criteria decision taking method. The criteria were applied in two case studies of automotive industry: the developments of a low-cost hatch vehicle and a mid-size luxury sedan vehicle, both designed for emerging markets.

How to use Weibull as tool for a decision making on field issues

Reliability, maintainability/serviceability and security are three qualities of product excellence desired by customers and users of products, however customer expectation for product reliability are continually increasing for almost all product and despite of most of the companies has worked on the philosophy of continuous improvement to meet or exceed the customer's expectations, its difficult to avoid failures or its difficult to ensure zero defect. Once it happens, it generate a customer complaint which is registered by companies. The way that companies used to register the complaints is through their warranty system and also a special database. Most of the companies maintain warranty databases for purposes of financial reporting and warranty expense forecasting. In some cases, there are attempts to extract engineering information from such databases. Another application is to use warranty data to detect potentially serious field reliability problems as early as possible.

In the automotive industries, time and parts production costs are fundamental, mainly in prototyping production. The RTV (Room Temperature Vulcanized) process is an important alternative production to flexible silicone molds when you need to inject polyurethane parts. The objective is time reduction in tooling production and parts. RTV requires notable initial investments in equipments. Many times, this cost does not fit in the automotive third part company's budget. This work shows how is possible to obtain parts by RTV process with excellent quality, without high investments in equipments and without quality loss in produced parts. Lead times and tooling and parts costs are analyzed. Due to equipments low costs, this alternative is accessible not only to automotive industries but also to small and medium suppliers.

Strategies and Proposals to Minimize Squeaks and Rattles - Strong Customers Enthusiasm Improvement Program

2002-11-19
2002-01-3561
According to several customer perception survey, Squeak and Rattle (S&R) is among the top most annoying defects. Consequently, GMB engineering design, development and validation process must be continuously improved and consistently applied to all platforms to guarantee that all products are free from squeaks and rattles. This paper introduces those concepts and discusses some strategies to eliminate or minimize S&R. Concepts and tests results are commented. Finally, the challenge in detection and analysis of S&R is discussed. Objective and subjective evaluation methodologies are being developed and suppliers training and integration have been improved

2000-01-3231
The present work gives an overview of the current situation of failures that may occur in automotive components, showing their distribution in the vehicle and the causes that make them occur, trying to emphasize the different materials which are used in the manufacturing of these components. This work is a technical approach strictly supported by an engineering concept which aims to discuss the different factors which contribute to cause premature failures of automotive components, prior to their utilization in the field or when they are exposed to the most variable conditions of use. One of the most important objectives of this study is to call the attention of design engineers, research engineers and manufacturing people to the importance of the components integrity which shall be taken into primary consideration in the design phase as well as in the specification of the material and process of manufacturing.
