This study aimed to economic evaluation of ostrich production in Sistan region by the use fuzzy conception in five platforms including (1 bird, 30 birds, 50 birds, 100 birds and 200 birds). The result showed that amount of benefit cost for 30, 50, 100 and 200 was 0.20, 0.26, 0.30, 0.31 and present value was 105, 549, 1460, 2927 million rials. According to the results obtained from present value...

We address the problem of workkow requirements speciica-tions under realistic assumptions that it involves experts from diierent domains (diierent business policies), where not all the possible execution scenarios are known beforehand. Using recent results on reasoning about actions, we formalize the notion of the speciications' correctness. To address this, we propose a high level language AW ...

Three dedicated approaches to the calculation of the risk-adjusted net present value (rNPV) in drug discovery projects under different assumptions are suggested. The probability of finding a candidate drug suitable for clinical development and the time to the initiation of the clinical development is assumed to be flexible in contrast to the previously used models. The rNPV of the post-discover...

In most practical cases, it is impossible to find an explicit expression for the distribution function of the present value of a sequence of cashflows that are discounted using a stochastic return process. In this article, the authors present an easily computable approximation for this distribution function. The approximation is a distribution function which is, in the sense of convex order, an...

This work addresses the problem of workflow requirements specifications considering the realistic assumptions that, it involves experts from different domains (i.e. representatives of different business policies); not all the possible execution scenarios are known beforehand, during the early stage of specification. In particular, since the main purpose of a workflow is to achieve a certain (bu...

A frequently encountered challenge in high-dimensional regression is the detection of relevant variables. Variable selection suffers from instability and the power to detect relevant variables is typically low if predictor variables are highly correlated. When taking the multiplicity of the testing problem into account, the power diminishes even further. To gain power and insight, it can be adv...

When countries attempt to stabilize annual inflation rates that are greater than 40 percent, the domestic stock market appreciates by 24 percent on average. The present value of the long-run benefits to shareholders of reducing high inflation outweighs the present value of the short-run costs. In contrast, the average market response is economically weak and statistically insignificant if the p...

Interaction Value Analysis is a modeling methodology originally intended to illustrate how full connectivity between members of an organization affects the shape of the organization. Technology is already transforming workplaces into fully-connected networks by providing instant access, subject only to the availability of the communication participants, as well as perfect knowledge of the abili...

The present value model says that an asset's price equals the sum of current and future discounted expected future payoffs from ownership of the asset. I explore the limits of the present value model by testing its ability to explain the pricing of storable commodities. For commodities the payoff stream is the convenience yield that accrues from holding inventories, and it can be measured direc...
