摘要:

The Central Electricity Generation Board of Britain is in the process of being privatized, and it has been suggested that the discount rate for investments used by the privatized entity should be much higher than the one previously used by the CEGB. This raises interesting conceptual issues which are relevant to both shareholder and publicly owned utilities. The analysis presented in this article suggests that in order to achieve the lowest economic cost of generation the privatized utility should continue to use the same discount rate it had when it was a government entity.

摘要:

This paper presents a new and better method for teaching the derivation of the appropriate form of a multi-attribute utility function under various assumptions of utility independence. This new method has three advantages over the usual mathematical method for teaching this subject. First, because our method is a natural elaboration of the method often used to teach single-attribute utility assessment, students learn multi-attribute utility assessment as an extension of single-attribute utility assessment. Second, because our method uses the same visual representation used in teaching single-attribute utility assessment (the tree), students who learn by using visual representations may learn the multi-attribute concepts better. Finally, our method clarifies the assessments needed to determine the weights for each term in the multi-attribute utility function.

摘要:

An estimate error may not be avoided when predicting future cash outcomes. The bounded interval estimate is a common allowance scheme to compensate for the inherent estimating error. We introduce the propagation of errors technique to evaluate capital investment alternatives with estimate errors. A number of examples are presented to show its adaptability in capital investment analysis. The results are then compared with other approaches.

摘要:

This case study examines the real situation where a considerable inventory savings exists by introducing an advanced manufacturing equipment that provides much needed manufacturing flexibility for a manufacturer of disks for airplane turbine engines. The case also documents the actual economic analysis procedures conducted by the firm by presenting the sensitivity analysis of the key input variables, probabilistic analysis and simulation analysis. Due to the nature of proprietary information, the actual company name has been disguised.

摘要:

For Analytic Hierarchy Process applications having separate benefit and cost output vectors, Saaty has recommended choosing a solution using a simple benefit/cost ratio procedure. But, even when benefits and costs are known with certainty and measured in dollars, it is shown that this procedure does not, in general, yield an optimal solution. An incremental analysis, with further specification of an appropriate cutoff rate, is shown to be required. Saaty's procedure is also shown to be sensitive to arbitrary semantic changes in benefit and cost labelling, while proper procedures, such as the one proposed herein, do not have that sensitivity.
