A further consideration when combining databases from multiple suppliers is how to identify and deal with redundant compounds. Here, some method of mapping multiple supplier information onto a single compound is needed for efficiency. Generally, all information can be mapped, although some consideration of cost and supplier reliability may allow a hierarchy of supplier information to be applied. 

Standards are available today in small pressurized cans that are extremely convenient to use with a gas-sampling valve for injection. Again supplier reliability with verification are a must. 

Therefore, for commercial suppliers, reliability issues have come more and more into the focus of engineering and research activities. Reliability has become a key parameter for the success of MEMS in a market with distinct safety implications [2-7]. 

Delivery Meeting time windows on delivery and supplier reliability are monitored here. 

Factories do not, as a general rule, analyse alkylbenzene supplies on a regular basis. Only occasional checks to monitor general quality are recommended, provided there is a long history of supplier reliability. It is however essential to check each batch of alkylbenzene used in research and development programs, or where the supplier is relatively unknown or problems in sulphonation are encountered. 

Supplier reliability measures the variability of the supplier s lead time as well as the delivered quantity relative to plan. Poor supplier reliability hurts responsiveness and adds to the amount of inventory the supply chain must carry.

Given a series of tests with the new material, the average yield x would be compared with Po. If x < Po, the new supplier would be dismissed. If X > Po, the question would be Is it sufficiently greater in the light of its corresponding reliability, i.e., beyond a reasonable doubt If the confidence intei v for p included Po, the answer would be no, but if it did not include Po, the answer would be yes. In this simple apphcation, the formal test of hypothesis would result in the same conclusion as that derived from the confidence intei val. However, the utility of tests of hypothesis lies in their generality, whereas confidence intei vals are restricted to a few special cases. 

Fewer parts means improved reliability, fewer stoek eosts, fewer invoiees from fewer suppliers and possibly fewer quality problems. 

Some operators are experieneing engine shutdowns beeause of autoignition problems. The response of the engine suppliers to reetify the situation has not been eneouraging, but the operators feel that the redueed reliability eannot be aeeepted as the norm. ... 

The advent of ISO 9000 certification has helped bring the quality issue to a focus. While ISO 9000 emphasis is on documentation of methodology and performance to the documented methods, the discipline that results is a direct step toward improvements in reliability. Out of this seems to come a goal of continuous improvement. This is a sharp contrast to the high growth era that took place in the early 1980s when poor quality on the part of the equipment suppliers was a significant factor in the lack of reliability at the field operation level. 

The RMDB consists of two mayor sections computer data storage and retrieval system, and backup microfilm data bank file. The computer data storage and retrieval system is used for die standard reliability and maintainability data listing, special calculations, and searches. This data bank system has been established to facilitate remote terminal access compatible with the GIDEP remote terminal programs. The microfilm data bank file is used for storage and distribution of supplier s documents, failure analysis curves, description of methods used in the collection of the data, and additional background information too extensive to include in the computer data bank. 

The requirements of the automotive industry are more demanding than some other industries. Automotive products have to be safe, reliable, and maintainable, protect the occupants, and have minimal impact on the environment in their manufacture, use, and disposal. The automotive sector is a very competitive market and as a consequence costs have to be optimized. There is little margin for excessive variation, as variation causes waste and waste costs money and time. Therefore several methods have evolved to reduce variation. Among them are SPC, FMEA, MSA, and many other techniques The automotive industry believes that the more their suppliers adopt such variation reduction techniques the more likely it will be that the resultant product will be brought to the market more quickly and its production process be more efficient. 

We aim for total customer satisfaction. Customers are those who buy our products our suppliers, our staff, and all people with whom we have contact. We will treat each other with care and respect and strive for excellence in all we do to provide a high level of service to all customers, internal and external. We will thereby provide finished products and services to the highest standards of quality, safety, reliability, and durability. 

In order to verify that the products or services meet the specified requirements you will need to carry out tests, inspections, assessments, etc. and these need to be performed against unambiguous standards of acceptability. You need to establish for each requirement that there are adequate criteria forjudging compliance. You need to establish how reliable is reliable , how safe is safe , how clean is clean , how good is good quality . Specifications often contain subjective statements such as good commercial quality, smooth finish, etc., and require further clarification in order that an acceptable standard can be attained. The secret is to read the statement then ask yourself if you can verify it. If not, select a standard that is attainable, unambiguous, and acceptable to both customer and supplier.

The reason for this requirement is so that data from the customer can be transmitted quickly and reliably. The customer may need to change quantities and delivery dates due to variations in production. This does not mean the changes will always be to shorten delivery times but on occasions the delivery times may need to be extended owing to problems on the assembly line or as a result of problems with other suppliers. The customer may not have made provision to store your product so urgently needs to be able to inform you to hold or advance deliveries. 

ECAR was established in 1967, and its current membership includes 29 major electricity suppliers in nine east-central states serving more than 36 million people. The current full members ol ECAR are those utilities whose generation and transmission have an impact on the reliability of the overall region. 

With the opening of the transmission network to all resource suppliers, many marketing entities entered the game in the mid-1990s. Many of these marketers are subsidiaries of already established gas suppliers. Some have been created solely for the electric industry. Still others have been formed from the utilities themselves. All of these etitities arc competition-motivated. Facility planning and reliability issues, while important to their business, are left to other organizations. 

Neutralizing capacity is not the only measure of a required amine feed rate. Once all acidic characteristics have been neutralized, amine basicity becomes the important issue because this raises the pH above the neutralization point, to a more stable and sustainable level. Consequently, in practice we are concerned with the level of amine necessary to raise the condensate pH to a noncorrosive level. This practical amine requirement is difficult to obtain from theoretical calculations because it must take account of the amine volatility, DR, and the boiler system amine recycling factor (as well as temperature). As noted earlier, the basicity of an amine has little or no relationship to its volatility or DR, so that reliable field results are probably a more important guide in assessing the suitability of an amine product than suppliers tables. 

Finally, the recording of many signals from the output of the analytic and electrochemical instrumentation requires a reliable multi-pen recorder or an equivalent recording system based on a data acquisition card and appropriate software. The recorded signals are normally in the range of a few mV to 10V. The use of reliable temperature controllers and thermocouples is also crucial for the success of the experiments. A lot of suppliers of such equipment can be easily found and will not be reported here. 

With spherical segments, optical figuring and testing is a proven and reliable process, well suited for mass-production. Serial production of diffraction-limited, large optics is already under way for laser fusion projects, with European suppliers increasing their capacity to approximately 1,000 m2 per year Aspherical segments would certainly be feasible as well, but the inherent risk and potentially lower quality need to be properly evaluated. In figuring optical... 

Each component shall be tested for conformity with all appropriate written specifications for purity, strength, and quality. In lieu of such testing by the manufacturer, a report of analysis may be accepted from the supplier of a component, provided that at least one specific identity test is conducted on such component by the manufacturer, and provided that the manufacturer establishes the reliability of the...
