The Illusion of Capacity in Supply Chain Models for the Semiconductor Industry

presentation slides

Organizations have put significant energy into making smarter decisions in their central planning for the integrated supply chain. But the fundamental representation of capacity and cycle time has remained static and linear - in direct contrast to the complex nature of capacity. This includes central planning for the production of semiconductor based package goods with respect to the first stage of production - Wafer Fabrication (FABs).

This presentation will outline the current start of practice for central planning, the FAB's complexity and the grand challenge of smarter representation of FAB capacity within the current structures.

Comparative Review of Classification Trees

This presentation describes the steps involved in tree methodology for classification purposes.

Classification refers to identifying probable responders to a marketing campaign, fraudsters in business practices, disease in clinical analysis for instance. In the world of large observational data sets, they typically contain missing values and models must be searched.

Tree modeling has the double advantage of being a search technique and of automatically impute missing values.

In this presentation, we will compare the two approaches by way of an example and, if time permits, we will also describe further developments in the area of tree modeling, such as gradient boosting.
