![]() ![]() This case study given in the paper can be an example of the effectiveness of evaluating other technical solutions in science, engineering, and technology. A case study for new sol-gel corundum 3SG46Hs12Vs grinding wheel instead of conventional white electro-corundum 25AF46L6V one has shown the former’s efficiency despite the lower price of the latter. The lack of a technical-and-economic model encourages irresponsibility and reckless use of valuable resources. The procedure is based on analyzing the boundary between a useful and useless technical solution. One of such possible procedures is developed in this paper. It requires a special procedure, depending on the specific case and conditions for making the cost-benefit evaluation decision. Third, a NPV that is equal to zero represents an indifference towards the project and the need to consider other non-monetary factors before proceeding with the investment.No quotient allows going directly from technical savings to saving time or money. From a financial standpoint, the investment should not be made. ![]() Second, a NPV that is less than zero would represent a loss of value to the organization if the investment were undertaken. 5 From a financial standpoint, these projects should be undertaken because they add value. The capital budgeting process can be viewed as a search for investments with a positive NPV. First, a NPV that is greater than zero adds monetary value to the organization. The calculation of NPV can result in one of three possible scenarios (Table 1). The NPV method is a measure of financial value and one approach to assessing the profitability of a proposed investment. The net present value (NPV) method includes the time value of money and is a superior method for long-term projects, such as those commonly encountered in the practice of anesthesiology. The discounted payback period rule includes the time value of money however, like the ROI method, it is limited by an arbitrary short-term cut-off period that is biased against long-term investments. It includes two main methods of discounting future cash flow. 5 The DCF method estimates the value of an investment’s projected future cash flows as if the cash flows were available today. The DCF method is superior to the ROI method for analyzing capital investment decisions because it incorporates the time value of money. Expressing these future cash flows in terms of their value today is known as the discounted cash flow (DCF) method. For example, one cannot disregard the cost reductions and cost savings of an AIMS resulting from reductions in anesthetic-related drug costs and increases in hospital reimbursement occurring beyond a cut-off period. The ROI method is biased against long-term projects and is based on an arbitrary, short-term cut-off date that ignores the investment’s performance after the cut-off point and disregards the possibility of growing cash flows after that point. However, it measures risk rather than investment returns. ![]() 1 - 4 The ROI method is easy to compute and understand (Table 1). The return on investment (ROI) method is commonly quoted in the analysis of capital investments affecting the practice of anesthesiology, such as the Anesthesia Information Management System (AIMS), handheld computer technology, and the Preoperative Evaluation Clinic. ![]()
