In this paper, an efficient multi-objective model is proposed to solve time-cost trade off problem considering cash flows. The proposed multi-objective meta-heuristic is based on Ant colony optimization and is called Non Dominated Archiving Ant Colony Optimization (NAACO). The significant feature of this work is consideration of uncertainties in time, cost and more importantly interest rate. A ...

In this paper, Economic Order Quantity ( ) based model for non-instantaneous deteriorating items with imperfect quality, permissible delay in payments and inflation is proposed. We adopt a time-dependent demand function. Also, the effects of time value of money are studied using the Discounted Cash Flow approach. Moreover, we assume that orders may contain a random proportion of defective items...

This paper describes a method of assessing the value of controllable devices such as Flexible AC Transmission Systems (FACTS) in a liberalized electricity market. A sophisticated algorithm using ac optimal power flow (OPF) is often unnecessarily detailed for the purpose of valuating such projects. Input parameters such as expected future generation mix is hard to guess and error prone. Therefor...

Unfortunately the fair value of a liability that is not actively or efficiently traded is not readily ascertainable through a financial market. This is in contrast to publicly traded assets such as bonds and stocks. However various approaches can be taken to determine estimates of such values based on discounted cash flow (DCF) techniques. Such techniques are also used to determine the fair val...

This paper shows that the standard textbook formula for computing the present value of a future random cash flow – the discounted expected value – is formally incorrect and can generate significant errors when used to compute present values. The correct present value method is provided as well as a simple adjustment to the textbook formula which can be used to obtain an approximation to the cor...
