Engineering cost analysis

Two different modeling cases were constructed for 1985 to measure the significance of EPA s underestimate. In the one case, the endproduct uses and resource prices were specified as parameters (engineering cost analysis) and in the other case, the endproduct uses and resource prices were determined as solutions...

Laboratory experiments, transport modeling, field data, and engineering cost analysis provide complementary information to be used in an assessment of the viability of an MNA approach for a site. Information from kinetic sorption/ desorption experiments, selective extraction experiments, reactive transport modeling, and historical case analyses of plumes at several UMTRA sites can be used to establish a framework for evaluation of MNA for uranium contamination (Brady et al, 1998, 2002 Bryan and Siegel, 1998 Jove-Colon et al, 2001). The results of a recent project conducted at the Hanford 100-N site provided information for evaluation of MNA for a °Sr plume that has reached the Columbia River (Kelley et al, 2002). The study included strontium sorption-desorption studies, strontium transport and hydrologic modeling of the near-river system, and evaluation of the comparative costs and predicted effectiveness of alternative remediation strategies.

It should be clear that a complete FMEA approach is not practical for the evaluation of production facility safety systems. This is because (1) the cost of failure is not as great as for nuclear power plants or rockets, for which this technology has proven useful (2) production facility design projects cannot support the engineering cost and lead time associated with such analysis (3) regulatory bodies are not staffed to be able to critically analyze the output of an FMEA for errors in subjective judgment and most importantly, (4) there are similarities to the design of all production facilities that have allowed industry to develop a modified FME.A approach that can satisfy all these objections.

If it deems it necessary, the USEPA can require an expedited response action (ERA) at a site that would require an immediate engineering evaluation/ cost analysis (EE/CA). After a removal action is completed or determined unnecessary, the long-term remedial action must be undertaken. First, a remedial investigation/feasibility study (RI/FS) is performed to determine a proper course of action. This can involve ... 

The chemical engineer (or cost engineer) must be certain to consider all possible factors when making a cost analysis. Fixed costs, direct production costs for raw materials, labor, maintenance, power, and utilities must all be included along with costs for plant and administrative overhead, distribution of the final products, and other miscellaneous items. 

Before a product goes into plant production, it is submitted for cost analysis by the accounting department. The necessary data are supplied by the laboratory director and the plant engineer. An example is given later in Section P, showing how the price of a dye is arrived at. 

The Project Manager and/or Cost Engineer reviewing a cost estimate must establish whether the costs in the labor column reflect base rates, loaded costs, or some intermediate value, such as base rate plus fringe benefits. Failing to do so would result in misleading material to labor ratios and incorrect cost analysis. 

Fortunately the scope of effectiveness of the TFCF can be modified and broadened by the judicious analysis of its cost components shown in Table 19.36. For lack of better information this breakdown is based on the typical cost breakdown in Table 10.1 after backing out the equipment and engineering costs...

A simplified flow for such a system exploration environment is shown in Fig. 2.6. For a given system configuration, a floorplanning tool could be used to extract related physical information. Then different feasibility analysis tools could be applied to evaluate the performance and cost of a given integration solution. Our cost analysis framework could be integrated to answer the what-if questions about the fabrication cost so that a cost efficient implementation could be identified. Of course, many other analysis engines are also required and we will further discuss these issues in the last chapter. 

An engineering economic analysis was performed in order to estimate the costs associated with the manufacture of SiC fiber by the process just described. The basis for the analysis was an assumed plant consisting of ten or more CVD reactors each 10 feet in length. It was assumed that a carbon tow substrate such asT-300 was being coated with...
