Case studies Method

This book discusses sampling and analytical protocol for indoor microbial contaminants. Included are case studies, methods for data interpretation, and discussions of future developments in the field of indoor bioaerosols. 

The research methodology used in this research is a case study methodology. Through this case study, it enabled several sources of evidences and practices to be highlighted. The case study also provides better understanding of the problems faced by the Malaysian automotive components manufacturer. The case study method allows researchers to retain the holistic and meaningful characteristics of the real-life events. Furthermore, the use of case study as a research method based on three conditions as follows [19] ...

AHP has also been applied together with case study methods in different areas like Evaluation of critical success factors of ISO 14001 implementation in a case study in Malaysia (Sambasivan and Fei 2008), Case study to the selection of a multimedia authoring system in software selection (Lai et al. 1999), Case study of design and evaluation of automated cellular manufacturing systems with simulation modeling and AHP approach (Chan and Abhary 1996), just to give some examples available in the literature. 

The case study method a very popular approach that attracts students and tends to encourage them into reflection. Their detractors argue that sometimes the cases used conunonly as examples because of their intrinsic interest are quite far from the real engineering practice. 

This chapter discusses research methods. The multiple case study method is reviewed and is followed by an assessment of the appropriateness of a case study approach. The data collection methods in general and the rationale for using interview and observation in this study to collect primary data are addressed. Archived data are outlined and the issues of reliability and validity are considered. Finally, simulation and simulation-based optimisation methods are introduced. 

Based on the research gaps identified in the last chapter, the multiple case study method has been employed. This method provides a better understanding of the detailed practical operations in Chinese medium-sized manufacturer SCs. They identify the key challenging issues in the case companies, develop appropriate strategies and generate the results in a wider context.

How should the accident cases be selected for in-depth investigations It is common to distinguish between statistical and clinical or case-study methods. In the first case, the accidents that are investigated should provide a representative sample of the total accident population. In the second case, on the other hand, the accidents that are investigated should provide in-depth knowledge about a certain type of accident of particular interest.

When considering secondary or enhanced oil recovery, it is important to establish where the remaining oil lies. Figure 8.21 shows an example of where the remaining oil may be, and the appropriate method of trying to recover it. The proportions are only an example, but such a diagram should be constructed for a specific case study to identify the target oil . 

The study of metastable ions concerns substances that have been ionized by electrons and have undergone fragmentation. The stable molecular ions that are formed by soft ionization methods (chemical ionization. Cl field ionization, FI) need a boost of extra energy to make them fragment, but in such cases other methods of investigation than linked scanning are generally used. 

In most cases, available methods are incomplete or unreliable, and some supporting experimental work is necessary The methods given here shomd allow theoretical feasibility studies, help minimize experimentation, and permit a measure of optimization in final design. 

The search for the optimum can involve many case studies. Often, if time is limited, a rigorous canned computer program is utilized. However, this is expensive. If time is not as much of a factor, the method prevented here will allow the calculations to be handled conveniently by hand or computer having limited core.

Appendix F is a case study by Hjertager et al. illustrating the above method. Such numerical methods will become more widely used in the long term. These techniques will probably remain research tools, rather than routine evaluation methods, until such time as available computing power and algorithm efficiency greatly increase. 

The two methods gave considerably different results when applied to the liquid hydrocarbon storage site case study. The TNT-equivalency method systematically...

Generally speaking, typical major incident conditions correspond to a release of some ten thousands of kilograms of some hydrocarbon at the site of a chemical plant or refinery that is characterized by the presence of obstructed and partially confined areas in the form of densely spaced equipment. The relative agreement with results derived from the multienergy method indicates that application of this concept is a reasonable approach for this case study. 

On the other hand, a TNT equivalency of 3% is expected to fail in situations where typical major incident conditions do not apply. This explains why the outcomes of the two methods applied to the storage site case study differed. 

In this section, three examples of blast calculations of BLEVEs and pressure vessel bursts will be given. The first example is designed to illustrate the use of all three methods described in Section 6.3.2. The second is a continuation of sample problem 9.1.5, the BLEVE of a tank truck. A variation in the calculation method is presented instead of determination of the blast parameters at a given distance from the explosion, the distance is calculated at which a given overpressure is reached. The third example is a case study of a BLEVE in San Juan Ixhuatepec (Mexico City). 

This book brings together a wide range of tools and techniques used by human factors and human reliability specialists, which have proved to be useful in the context of human performance problems in the CPI. Although many human factors practitioners will be familiar with these methods, this book is intended to provide ready access to both simple and advanced techniques in a single source. Where possible, uses of the techniques in a CPI context are illustrated by means of case studies.

QUANTIFICATION PROCEDURE. In order to illustrate the SLIM quantification method, the case study developed in the earlier part of the chapter based on the chlorine tanker filling example will be used. The following operations from Figure 5.6 will be used to illustrate the method.
