Quality of a layout has the most direct impact in the manufacturability of a design. Traditionally, layout quality is ensured in the first order by design rules, i.e. if a layout is free of design rules violation, it is a good layout. It is assumed such a layout will be fabricated to specification. Moreover, a design rule clean layout also ensures the electrical performance of the circuit it re...

This research presents several heuristics to optimize the location of crossovers in a conveyor-based Automated Material Handling System (AMHS) for a semiconductor wafer fabrication facility. The objective is to determine the location of crossovers that minimizes the total cost of the expected work-in-process on the conveyor and the cost of installing and operating the AMHS with the crossovers. ...

This paper presents the layout and functionality of Version 2 of the Taxonomy Workbench and Theory Demonstrator which is being developed at the Centre for Cognitive Science. The Theory Demonstrator uses multimedia/multimodal hypertext to present the taxonomy of unimodal output modalities which has been developed as part of addressing the research agenda of Modality Theory. The Workbench functio...

This paper presents a new approach for the optimal facility siting considering the uncertainty of toxic release in one of the installed facilities. The proposed formulation incorporates the effect of wind speed, wind direction and atmospheric stability to calculate the risk of death via probit functions and Monte Carlo simulation. The overall problem is initially modeled as a disjunctive progra...
