Classification criteria

The literature classification criteria are chosen to represent the most important dimensions of the supply chain configuration problem, as well as describe general characteristics of papers. These dimensions have been identified in previous chapters of the book. Importance and values for each criterion are defined as follows  

This criterion describes which tiers of the supply chain are considered in a paper. It allows judging about units assigning the largest value to configuration decisions. Typical values are supply tier, manufacturing tier, distribution tier, and customer tier. In many papers, the whole supply chain is covered, implying that all tiers are under similar levels of consideration. 

As with specific problems, a particular general problem (e.g., globallzatirMi, coordination) can be the focus of a supply chain configuration study. 

The criterion characterizes a modeling technique used to solve the supply chain configuration problem. Analysis of this criterion reveals the most often used techniques. Values of the criterion include different methods of mathematical programming, simulation, statistical analysis, data modeling, and hybrid techniques. Usually, one method is indicated unless several methods having similar importance to decision-making are used. 

Not aU papers can be classified according to each criterion. For instance, the application area is not defined in all papers.

It is an autoantibody whose autoantigen is the Fc portion of IgG. Rheumatoid factors may be of any immunoglobulin isotype but it is IgM rheumatoid factor that is commonly measured in rheumatoid arthritis. Classification criteria for rheumatoid arthritis include only one serological test, namely rheumatoid factor. However, it is not diagnostic test rather it may be confirmatory when a number of other clinical features are present. 

These classification criteria are summarised in the diagram below ... 

The only difficulty in this method (in addition to the calculations, which are easily carried out using computers) is the fact that it is impossible to analyse tables with values that are missing, so there is a need to choose substances for which there are a whole range of LC and LD values. Since this is impossible, three tables were used, which all have in common the L050 variables for rat and mouse, orally and by intraperitoneal means of penetration, so that the coherence of the three tables and a strong enough relationship between them could be ablished. The purpose was to determine, if, in the absence of one of the classification criteria set by regulation, it was possible to choose another available criterion to determine the risk level of toxicity.

The goal of an effective VTE prophylaxis program is to identify all patients at risk, determine each patient s level of risk, and select and implement regimens that provide sufficient protection for the level of risk. OAt the time of hospital admission, all patients should be evaluated for their risk of VTE, and strategies to prevent VTE appropriate for each patient s level of risk should be routinely employed. Prophylaxis should be continued throughout the period of risk. The risk classification criteria and recommended prophylaxis strategies published... 

Comments on some trends and on the Divides in the Periodic Table. It is clear that, on the basis also of the atomic structure of the different elements, the subdivision of the Periodic Table in blocks and the consideration of its groups and periods are fundamental reference tools in the description and classification of the properties and behaviour of the elements and in the definition of typical trends in such characteristics. Well-known chemical examples are the valence-electron numbers, the oxidation states, the general reactivity, etc. As far as the intermetallic reactivity is concerned, these aspects will be examined in detail in the various paragraphs of Chapter 5 where, for the different groups of metals, the alloying behaviour, its trend and periodicity will be discussed. A few more particular trends and classification criteria, which are especially relevant in specific positions of the Periodic Table, will be summarized here. 

Similar classification criteria may be made by using the total valence-electron concentration previously defined (see equation 4.27) and defining, according to Parthe (1995) the tetrahedral structure equation ...

In the chemical safety report, the hazard assessment of a particular substance is based on the data set provided in the technical dossier. This contains substance-specific information on physicochemical properties as well as on toxicological and ecotoxicological hazards. One objective of the hazard assessment is the substance s hazard identification, which comprises the determination of its physicochemical and hazardous properties for the purpose of classification. Concerning human health hazards, both human and nonhuman information is taken into consideration and evaluated with respect to the classification criteria laid down in the Dangerous Substances Directive and in the CLP Regulation, respectively. However, in most cases human data do not exist, so the hazard identification has to be based on data from animal experiments. With respect to teratogenicity, this hazardous property may in principle be detected in the following toxicity studies ... 

Manufacturers, importers, or downstream users usually classify and label chemicals under their own responsibility. This approach is called self-classification. It means that companies evaluate all available information concerning the intrinsic properties of a particular substance or mixture by applying to it the relevant classification criteria. However, since the available information or interpretation of data may differ from one company to another, each self-classification may result in a different classification and labeling for the same substance. From a regulatory point of view, classification and labeling discrepancies are problematic because they impede a consistent hazard communication on the chemicals market and may put at risk the appropriate protection of humans and the environment.
