Attributes, supplier

The combined grey system theory and uncertainty theory-based approach for supplier selection is proposed to solve the multi-attribute supplier selection problem. The grey system theory is employed because ffie selection of supplier attributes... 

Several classes of ABS which show the above general characteristics but with specific attributes are recognised. One supplier for example classifies ABS materials into the following categories ... 

Where you have required your subcontractors to send a certificate of conformity (CofC) testifying the consignment s conformity with the order, you cannot omit all receiving checks. Once supplier capability has been verified, the C of C allows you to reduce the frequency of incoming checks but not to eliminate them. The C of C should be supported with test results. Therefore you need to impose this requirement in your purchasing documents. However, take care to specify exactly what test results you require and in what format you require them presented, as you could be provided with attribute data when you really want variables data. 

The trick is to meet EuroVI at affordable cost, while retaining the fuel economy and drivability attributes that are keys to Diesel s acceptance in the marketplace. Now the question is what is the best way to meet it A variety of options must be considered cost, robustness, complexity and application constraints. As 2007 begins, car manufacturers and suppliers are scrambling to make sure that, whatever they commit to in production, it will not be more costly than what the other companies devise. Over the past few years and for a long time, Diesel clean-up has been a very competitive and strategic field. 

The major causes of spectral variation were (1) instrumental drift, as Goodacre and Kell realized, but also (2) sample history, as discussed above. In particular, variations in the supplier or even the batch of tryptic soy agar (TSA) used for cell culturing led to spectral variations that differed in degree among disparate species. This phenomenon was attributed to the differential metabolic capabilities of the species with respect to the changed nutrients. 

Potassium nitrate in cloth sacks stowed next to baled peat moss became involved in a ship fire and caused rapid flame spread and explosions [1]. Heat transfer salt from a new supplier was added to a pilot plant reactor salt bath. Some 12 h after start of heating to melt the bath contents a muffled explosion occurred, attributed to presence of organic impurities in the new salt [2],... 

For any new excipients, APIs or drug products (where new does not necessarily mean novel, but new to the receiving site) there are additional testing criteria, e.g. supplier audits, third-party contract laboratory audits, analytical method transfers, sample management/tracking, etc. For those key excipients, where there is on-site historical experience, it still behoves both parties to check whether the local grade/supplier used by the CMO is equivalent to that used by the supplier (Worsham, 2010). There are many examples of differences in excipient physical properties, e.g. particle size, which have been attributed to different excipient sources that could ultimately impact on the performance of those excipients in formulated products (Frattini and Simioni, 1984 Dansereau and Peck, 1987 Phadke et al., 1994 Lin and Peck, 1994). 

While matrix effects are generally attributed to sample constituents, sample preparation can also lead to matrix effects. Mei et al. [115, 124] demonstrated that matrix effects could be caused by the brand of sample tubes that are used in the sample storage step of the assay. In this example, the solution was to switch to a different supplier for the tubes. In addition, while it is generally reported that... 

As with other packaging components, the incoming tests and specifications of metered valves, inspection attributes, and AQLs (acceptable quality levels) will need to be coordinated with the supplier. The valve should be considered as a critical package component and have incoming performance tests, such as spray weights and weight loss [13,14], The performance test could be conducted on a sample of the valve lots from either scale-up or pilot trials before the validation lots are prepared. This information may also be available for each lot from the supplier. It is recommended that each test shown in Table 3 be conducted on at least three valve lots as part of the validation program. 

Every application needs to be evaluated on its merits for the range of properties required. A database of previously successful applications is a distinct advantage. An analysis of the main attributes of an application is needed, e.g., compression, shear, static, dynamic, or wear. Many of these factors are not on the supplier s data sheets and the information needs to be obtained from the supplier or by experimentation. 

No matter what tool is used to determine if the vendor is appropriate for the scope of work, the real challenge begins with the negotiation of the contract and subsequent initiation of the work. Any vendor or supplier is an extension of the sponsor firm s operations. Ultimately they are partners in the outcome of the project. Supplier partnership is a concept that can be applied to any supplier. Suppliers are viewed as an extension of the customer s overall operation. Critical attributes of a partner relationship are... 

The extent and breadth of these attributes will vary, depending on the status of the supplier-customer relationship. Initiation of a partner relationship generally begins at the qualification stage. The previously mentioned tools of vendor category and regulatory requirements set the foundation for the vendor qualification program. 

In this age of low cholesterol, low fat foods, replacement of a portion of red meat with vegetable protein in heat-and-eat prepared foods is very attractive to both consumer and supplier. However attempts to add a significant portion of soy protein to fresh ground beef have been less than successful based on consumer acceptance. Perceived changes in the traditional psychophysical attributes of hamburger are the major causes of product rejection (1.2). 

Readers can obtain the latest and more detailed data and information from suppliers and/or software programs. The guides presented in this book only provide a means to compare the general performances of different plastics. Since new developments in plastic materials are always on the horizon it is important to keep up to date. It is important to ensure that the fabricating process to be used to produce a product provides the properties desired (Chapter 3). Much of the market success or failure of a plastic product can be attributed to the initial choices of material, process, and their cost. 

There are numerous types of paint employed in the protection of steel and they are designed to meet the conditions imposed by the environment in which they are expected to function. For steel exposed to the atmosphere, the most common type of paint system is based on alkyl resin and this may be mixed with other types or may itself be chemically modified for a specific purpose, e.g. vinyl toluenated or styrenated to give rapid drying. Other generic types are chlorinated rubber, vinyl, acrylic, epoxy, and polyurethane. All have particular attributes and limitations and selection is usually a matter of discussion between user and supplier. 

This requirement is usually met by means of the audit conducted by the pharmaceutical or healthcare company. The audit examines the quality assurance attributes of the supplier s process, the firm s general capability maturity, and the suitability of its equipment or service suggested for use on the project. Suppliers in this context may be understood to include equipment vendors, service suppliers, or the pharmaceutical or healthcare company s in-house software development department. Regulators hold pharmaceutical and healthcare companies accountable for the use of suppliers whose capability assessment indicates their inability to deliver validatable, compliant software. ...
