摘要:

Investment in chlorine plants presents an interesting problem in engineering economics. The size of the electrolytical cells and their designed current density must be selected from a wide range of technically feasible alternatives, with different cost implications. This study develops a minimum-cost criterion, which is consistent with the present value maximization principle of investment ranking, and builds it into a computer program for current density and cell size optimization in mercury-type cell installations. In an industrial application the program would find the optimum under technical and economic specifications given by the investor. The analysis in this paper is based on results obtained with a set of hypothetical but realistic technical functions, used in conjunction with over one hundred successive parametric combinations pertaining to the investment situation. How plant size, electrolytical power rate, price of mercury, cost of capital, economic life and tax-depreciation affect optimum cell-room design are explored, and the potential financial losses attributable to non-optimal solutions are estimated.

摘要:

This paper concerns itself with providing the means by which a decision-maker may choose among competing projects and arrive at the optimal allocation of the firm's scarce dollar resources. The problem is handled in the mathematical programming framework. The model holds with or without the assumption of capital rationing and permits the incorporation of the effects of growth and of alternative financial mixes on the cost of capital for the firm. When iterated, the model equates marginal revenue to marginal cost, thus yielding the optimal investment level for the firm. Several investment alternatives not considered in the existing literature on the subject are examined, and some novel interpretations of the constraints and results are offered.

摘要:

This paper presents a procedure for calculating system and component utilization patterns or load curves which describe the use of a single service facility by several independent agencies. Such load curves are frequently used to allocate cost of the facility among the agencies it serves. The procedure is a computer model that establishes a link between data that are readily obtain ed and data that are required by allocation formulas. The model derives detailed load curves for each agency and for the-total system. A Monte Carlo procedure is suggested in which the model may be used to estimate the sensitivity of allocation formulas to error in the underlying data.

摘要:

Five of the seven factors in most common use for compound interest calculations involve a uniform series of payments (or receipts). These interest factors, for use when interest is compounded at discrete points in time, are commonly referred to as the uniform series present worth factor, the uniform series compound amount factor, the capital recovery factor, the sinking fund factor and the uniform series gradient conversion factor. The proper use of these five factors requires that the period of time between the compoundings of interest coincide with the period of time between the uniform payments. If the interest is compounded more frequently (assume by an integer number of times) than the payments, then the best way to apply the compound interest factors is to determine the effective interest rate between payments. If interest is compounded less frequently than the payments (assume there are an integer number of payment periods within each compounding period), the correct solution procedure is not well known. Three methods are discussed for solving problems when interest is compounded less frequently than payments are made. It is argued that the method proposed in this note is better than the other two methods in popular use from both a theoretical and practical standpoint.
