Hurricane forecasts are intended to convey information that is useful in helping individuals and organizations make decisions. For example, decisions include whether a mandatory evacuation should be issued, where emergency evacuation shelters should be located, and what are the appropriate quantities of emergency supplies that should be stockpiled at various locations. This paper incorporates o...

earned value management (evm) is the process of integrating the time and cost management within the framework of project scope management. the earned value has provided methods for predicting the cost for projects. in large part, these methods have not been improved upon since their beginnings and remain unsubstantiated as to accuracy. in this direction, several mathematics formulas have been d...

Forecasting the unit cost of every product type in a factory is an important task. However, it is not easy to deal with the uncertainty of the unit cost. Fuzzy collaborative forecasting is a very effective treatment of the uncertainty in the distributed environment. This paper presents some linear fuzzy collaborative forecasting models to predict the unit cost of a product. In these models, the...

Accurate load prediction is an effective way to reduce power system operation costs. Traditionally, the Mean Square Error (MSE) a common-used loss function guide training of accurate forecasting model. However, MSE unable precisely reflect real costs associated with errors because cost caused by in probably neither symmetric nor quadratic. To tackle this issue, paper proposes generalized cost-o...

At a Glance: This article describes a prototype of a discrete event simulator-Y4 (Yield Forecaster)-capable of simulating defect related yield loss as a function of time, for a multi-product IC manufacturing line. The methodology of estimating yield and cost is based on mimicking the operation and characteristics of a manufacturing line in the time domain. The effect of particles introduced dur...

This article discusses how to quantify the forecasting quality of IT business value. We address a common economic indicator often used to determine the business value of project proposals, the Net Present Value (NPV). To quantify the forecasting quality of IT business value, we develop a generalized method that is able to account for asymptotic cases and negative valued entities. We assess the ...

[//129]Abstract Two major problems in selecting experts for the Delphi Technique in cost sensitive educational forecasting are considered: 1. Differentiation between levels of expertise; 2. The relevance of experts in forecasting areas where the subject matter is cultural values rather than technology. It is hypothesized that where values comprise the forecast subject matter there will be no si...

decision making on budgeting is one of the most important issues for executing managers. budgeting is a major tool for planning and control of projects. in public and non-profit organizations and institutions, estimating the costs and revenues plays an important role in receiving credit and budgeting. in this regard, in the present paper the case of isfahan municipality is considered. one of th...
