Design-analysis philosophy

One of the earliest innovative approaches to product development with direct implication for design for the environment was product-aimed rationalisation based on the value analysis philosophy [5], This systematic method for achieving the necessary functions of a product at the lowest possible cost starts, in contrast to traditional cost-reduction methods, by asking such fundamental questions as ... 

Clauses A.3.1 through A.3.8 provide examples of methods used by some owners/operators in evaluating existing SIS. These methods are provided as examples and should not be considered the only acceptable approaches. The owner/operator should select a method or methods based on their hazard- and risk-analysis philosophy and prior design practices with consideration for the following ... 

Section 2.1 briefly presents the design philosophy employed to guide the design analysis process, while Sect. 2.2 discusses the key design objective that were established. 

Although national standards that cover the basic design philosophy are available, these have serious tunitations when apphed to this type of structure. The aim of this section is to demonstrate how the limitations may be overcome by imdertaking fundamental design analysis, and also to indicate those critical areas that demand special consideration. The detailed design analysis presented here considers the possibility of failme due to local instabihty, the effect on the dynamic response of the flexible foxmdation provided by the platform, and the determination of thermal stresses at critical locations. 

The first problem area of the so-called anisotropic analysis will be broken down into two subareas shear-extension coupling and bend-twist coupling. We have already observed for the most complicated laminate in the design philosophy proposed earlier that the A,q and A26 stiffnesses are both zero. There is no shear-extension coupling in the context of that philosophy. However, in contemporary composite structures analyses, it is relatively easy to include the treatment of shear-extension coupling, so you should not be overwhelmed by that behavioral aspect or by the calculation of its influence. 

The first task in applying a spacing table to a facility is to ensure it corresponds to the philosophy of protection adopted by the company. Where limited space is available to provide the required spacing, an examination of the equivalent fire and explosive barriers or active fire suppression system should be confirmed. This analysis should be accepted by the company as part of the design risk analysis. 

Our philosophy in preparing this book has been to include information that will help the user make decisions. In this respect, we envision each table to be something the user will consult when reaching a decision point in designing an analysis or interpreting results. We have deliberately chosen to exclude information that is merely interesting, but of little value at a decision point. 

A common mistake in many safety reviews is to delve into the analysis without a basic understanding or agreement of how the facility was designed or intended to be operated. Prior to a discussion of the hazards and consequences, the team should identify and agree to the design philosophy of the facility under review. Sometimes, some features of a facility are assumed, but never documented.
