Cost element methodology

To consider differences in design (e.g., number of cavities, material, etc.), individual correctional factors can also be used, which leads over to the next methodology to be described the cost element methodology, which is also called variable costing.

However, when a firm commitment to build a plant is under consideration, detailed assessment is normally required of all cost elements and of everything that can go wrong and affect the viability of the proposed commitment. The process is described as risk analysis. Many treatises and methodologies are available, as befits the gravity of a subject which can seriously affect the fortunes of major enterprises. We will address the fundamental aspects. 

The developed methodology is illustrated in Figure 1. The overall model consist of four blocks. The inputs of the model are introduced in the Inputs block. The inputs are processed in the Data Process block and then considered for the Simulations block. In the Simulations block, processed climate series, forecasted failure behaviours and vessel accessibihty and operabiUty values are synthesised and OPEX calculations are performed. The cost elements which influence offshore O M activities are then employed along with these results to support the decision making. Final decision choices are determined not only from a power production point of view, but also in terms of cost, revenue and profit. 

Neither of these processes has been commercialized, although some aspects of the methodology were incorporated into a plant operated for a short time by the Elcor Company (31). This company, which operated briefly in western Texas in 1968 using natural gypsum, is the only one known to have commercially attempted to recover elemental sulfur from this material by a two-step thermal process. The Elcor plant was shut down shortly after it began operation. Although most technical problems were said to have been solved, production costs were prohibitive. 

Information on collection, one of the most costly functional elements, is presented in four parts deahng with (1) the types of collection services, (2) the types of collection systems, (3) an analysis of collection systems, and (4) the general methodology involved in setting up col-lec tion routes. 

We have already seen elements of the CA approach when considering the costs due to safety critical failures. A further insight into the way that failure costs can be estimated for non-safety critical failures is also used to support the CA methodology. Estimates for the costs of failure in this category are based on the experiences of a sample of industrial businesses and published material as follows. 

Interest in the development of synthetic schemes and approaches to create molecular recognition elements has blossomed during the past half century for a number of reasons. In contrast to biologically based receptors, artificial mimics have the potential advantages of being less costly, more stable, and better able to withstand harsher conditions.7-12 Furthermore, synthetic methodologies can be used to create receptors for molecules for which an artificial receptor does not exist. These designer materials have enormous potential in catalysis, clinical and pharmaceutical applications, chemical sensors, separation science, and electronics.7-12... 

In this chapter, two aspects of analysis are considered. Firstly, the digestion step of contaminated soil samples is discussed. Secondly, the various techniques of determination of all relevant elements are considered. Important criteria for selecting an analytical technique include detection limits, analytical working range, sample throughput, cost, interferences, ease of use and the availability of proven methodology. These criteria are discussed below for the major atomic spectroscopic techniques.
