摘要:

The productivity of a two-station production line is determined by the station breakdown and repair rates, and by the capacity of the lncerscaclon buffer. A model which describes the station breakdown and repair rates as functions of the maintenance and repair inputs to the system la presented.The production function is Incorporated Into a profit function. The values of maintenance, repair, and an aggregate materials-labor inputs aa well as the capacity of the interstation buffer which maximize profit are sought.

摘要:

This paper reports The results of a survey research study of The capital budgeting practices on non-Indus trial (service) corporations, specifically firms in the 1983FortuneService 500 Listing. The survey questionnaire was designed to provide data regarding the entire capital budgeting process - from searching for investment opportunities through post auditing implemented projects. Also, It elicited ‘opinions’ as to the degree of difficulty and degree of importance of various phases of the capital budgeting process. The results indicate that, overall, large service corporations are not as sophisticated in regards to capital budgeting as theory would allow. The most serious weaknesses seem to be the areas of risk assessment, risk adjustment and use of post audits.

摘要:

The use of transform techniques can greatly enhance The task of modeling cash flows. Considerable work has been done since Crubbatrom's on the application of transform technique to cash-flow analysis. However, little attention is given to transform techniques by the engineering economics community at large, as evidenced by the lack of ita coverage In engineering economy textbooks. This paper represents the continual effort of the authors to suggest the use of transform techniques for engineering economy problems. A loan problem is formulated using the traditional method, the Zeta-transform method, and a difference equation approach using matrix methods. Simplified results are obtained using closed-form solutions from both the transform and difference equation methods. The loan problem is extended to an equipment financing situation, which is formulated using the Zeta-transform method and the traditional method as well. An illustrative example is included.

摘要:

This paper provides a criterion that can be applied to evaluate mutually exclusive investment options with different economic lives in an inflationary environment. This criterion - denoted as the equivalent real annual cost procedure - is more computationally efficient thatn the alternative "replacement chain" approach. Moreover, the equivalent real annual cost method is remarkably similar in its calculations and in its intuitive appeal to the well known equivalent annual cost method.

摘要:

We show that when a project is financed with amortized debt, traditional capital budgeting procedures may lead to biased net present values. A model is presented, based on the seminal work of Modigliani-Miller, which allows the net present value of a project to be determined by a weighted average cost of capital that varies with the amortization process.
