Forecasting Cost and Yield

چکیده
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 during wafer processing as well as changes in their densities due to process 2 improvements are taken into account. A spectrum of results are presented for a manufacturing scenario to demonstrate the usefulness of the simulator in formulating IC manufacturing strategies.

The aim of this study is to present a new method to predict project time and cost under uncertainty. Assuming that what happens in projects implementation which is expressed in the form of Earned Value Management (EVM) indicators is primarily related to the nature of randomness or unreliability, in this study, by using Monte Carlo simulation, and assuming a specific distribution for the time an...

Earned value management (EVM) has prepared some methods to forecast final costs of projects. These methods were not developed since the start of formation and were gradually completed, of course with one exception that is its authenticity, they are still remained unchanged. At the present time EVM guide does not apply from schedule indices to forecast schedule for completion of project and ...

Introduction Reliable and timely forecasts provide important and useful input for proper, foresighted and informed planning, more so, in agriculture which is full of uncertainties. Agriculture now-adays has become highly input and cost intensive. Under the changed scenario today, forecasting of various aspects relating to agriculture are becoming essential. But in-spite of strong need for relia...
