Production of aluminum alloy clad strips requires many processes, and a reduction in the number processes has long been demanded. A method to cast directly from molten metal using twin roll caster with copper rolls is proposed this work. Two types casters were designed tested. One was vertical-type tandem other equipped scraper. The casting conducted an oxidizing atmosphere. at speeds higher th...

In this work we propose a simultaneous scheduling and control optimization formulation to address both optimal steady-state production and dynamic product transitions in multiproduct parallel continuous stirred tank reactors. The simultaneous scheduling and control problem for multiproduct parallel continuous reactors is cast as a Mixed-Integer Dynamic Optimization (MIDO) problem. The reactor d...

This paper addresses the common cycle multi-product lot-scheduling problem in flexible flow lines (FFL) where the product demands are deterministic and constant over a finite planning horizon. Objective is minimizing the sum of setup costs, work-in-process and final products inventory holding costs per time unite while satisfying the demands without backlogging. This problem consists of a combi...

In this report, we examine the workflow management process from a scheduling perspective. Recognizing that effective workflow management requires an ability to efficiently allocate limited resources to tasks over time, we concentrate on characterizing this domain as a continuous distributed scheduling problem and on understanding the requirements and opportunities for providing workflow schedul...

Structured Abstract Page Purpose Powered-wheelchair transducers and systems are presented that provided more control, reduced veer on slopes, and improved energy conservation, while reducing effort. They are especially significant for people with movement disorders who lack sufficient hand-grasp and release ability or sufficient targeting skill to use joysticks. Design/methodologies/approach La...

This paper discusses how simulation was used to evaluate and characterize the scheduling issues in a semiconductor fab and the subsequent implementation of an integrated scheduling solution. The scheduling system was integrated with the fab MES and a number of other data sources including an integrated machine standards database, preventative maintenance scheduling and a Kanban stage calculatio...
