Research ArticleOpen accessEvery word in the titleCost Analysis of a Two Dissimilar-Unit Cold Standby Redundant System Subject to Inspection and Random Change in UnitsG. S. Mokaddis, C. H. MattaProblem statement: This study deled with the cost analysis of a two dissimilar unit cold standby redundant system subject to inspection and random change in units. In this system each unit works in two different modes normal and total failure. Assuming that the failure, repair, post repair, interchange of units and inspection times are stochastically independent random variables each having … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,298 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestment, Taxes and the Cost of Capital: An Euler Equation Specification TestHuntley SchallerProblem statement: Previous studies (primarily employing goodness-of-fit tests) have found it difficult to provide clear and direct evidence that taxes and the interest rate have a strong influence on investment. Approach: The objective of this study was to test whether the cost of capital, which includes taxes and the interest rate, affects investment. This study used the Euler equation for … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 7,616 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleCost Elasticities of Reliability and MTTF for k-out-of-n SystemsAli Muhammad Rushdi, Abdulaziz Efain AlsulamiThe application of the concept of cost elasticity of reliability was extended from the parallel system to the partially redundant or k-out-of-n:G(F) system (or k-out-of-n system, for short). An expression for the cost elasticity of reliability was derived for a general k-out-of-n system. The expression yielded acceptable results for a wide range of values for k, n, and component reliability. … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 7,295 accessesView PDFCite
