Selection and Evaluation

On the basis of the results of the drying tests that establish size and operating charac teristics, formal quotations and guarantees shoiild be obtained from diyer manufacturers. Initial costs, installation costs, operating costs, produc t quality, diyer operability, and diyer flexibihty can then be given proper weight in final evaluation and selection. 

In evaluation and selection of a filter medium, one should account for the fact that hydraulic resistance increases gradually with time. In particular, the relationship between cloth resistance and the number of filter cycles is defined by ... 

Materials evaluation and selection are fundamental considerations in engineering design. If done properly, and in a systematic manner, considerable time and cost can be saved in design work, and design errors can be avoided. 

Notwithstanding the guidance given below under Evaluation and selection of subcontractors, this requirement does not relieve you of the responsibility for ensuring the quality of subcontracted parts, materials, and services. Therefore, it would be unwise to place orders on a customer-specified subcontractor without first going through your evaluation and selection process. You can obviously take some short cuts but don t make assumptions. The customer will not be sympathetic when you are late on delivery or your price escalates. If you find a subcontractor that can meet all your product/service requirements at a lower price you can submit details to your customer for approval. 

The standard requires the supplier to evaluate and select subcontractors on the basis of their ability to meet subcontract requirements, including the quality system and any specific quality assurance requirements. 

You need to develop documented procedures that define your subcontractor evaluation and selection process and in certain cases this may result in several closely-related procedures for use when certain conditions apply. Do not try to force every purchase through the same selection process. Having purchasing policies that require three quotations for every purchase regardless of past performance of the current subcontractor is placing price before quality. Provide flexibility so that the policies and procedures complexity match the risks anticipated. Going out to tender for a few standard nuts and bolts would seem unwise. Likewise, placing an order for lm of equipment based solely on the results of a third party ISO 9000 certification would also seem unwise.

Coatings, cathodic protection, and chemical additives are used extensively to prevent internal and external pipeline corrosion. The excessive use of incompatible chemical additives has caused severe problems in gas-transporting systems. Costs arising from these problems often exceed the costs of the chemicals themselves. The careful evaluation and selection of chemical additives can minimize these problems and reduce operating costs [I860].

When the trial site is not on a special research facility, the evaluation and selection of held investigators (farmers) may be difficult. The best trial results are normally obtained from those trials conducted on farms where the farmers or techni-cians/agronomists involved with the normal application of pesticides on the farm are involved in the conduct of the trial, and are aware of the objectives so that they avoid treating the trial area with products likely to interfere with the analysis. 

The creative part of the design process is the generation of possible solutions to the problem (ways of meeting the objective) for analysis, evaluation and selection. In this activity the designer will largely rely on previous experience, his own and that of others. 

The designer starts with the set of all possible solutions bounded by the external constraints, and by a process of progressive evaluation and selection, narrows down the range of candidates to find the best design for the purpose. 

A system for synthesis design working with a database of reactions will initially contain only a few reactions and thus produce only a few alternatives. Thus, evaluation and selection are not very important. However, as the size of the database is expanded, more and more alternatives will be obtained for a given target structure. Here again, the development of a general evaluation and selection package will be required to handle the various transforms of the database. 

Naturally, there must be differences in the two types of search procedures. However, they do not originate in the mechanisms for generating reactions the latter is achieved for both types of searches via the formal reaction schemes. Instead, the differences come from the way in which the reactions are evaluated and selected. The various... 

These four procedures are all recommended to be performed in the order shown to achieve optimal parameter estimation followed by a final validation of the gravity sewer process model (Figure 7.7). In the case of design of a new sewer system, procedure number 4 is, of course, not relevant and kinetic parameters for the sewer biofilm must be evaluated and selected based on information from comparative systems.
