Shop-floor Life Cycle Assessment

Framework for the Performance Assessment of Shop-floor Control Systems

In this paper we discuss the concept and design criteria for a framework that facilitates the performance assessment of shop-floor control systems. Our basic concept includes a simulation model that emulates the shop-floor of a wafer fab, sends information to the control system, and receives information back from the control system. The shop-floor control system is realized as a separate module...

Food Polymeric Packaging Life Cycle Assessment (LCA)

  Food packaging is used to maintain the safety and quality of food during distribution and storage and to protect them from adverse internal and external conditions, such as water vapor, spoilage due to microorganisms, moisture, light, and dust. In this regard, lots of research studies have been done to increase shelf life, safety, and quality to create suitable physico...

Simulation Based Shop Floor Control

This paper presents an overview of simulation-based shop floor control. Much of the work described herein is based on research conducted in the Computer Integrated Manufacturing (CIM) Lab at The Pennsylvania State University, the Texas A&M Computer Aided Manufacturing Lab (TAMCAM), Technion in Israel, and the University of Arizona CIM lab over the past decade. In this approach, a discrete event...

Multiscale Life-Cycle Assessment

A streamlined life-cycle assessment (SLCA) is typically performed at the scale of the completed product. One could also, however, perform SLCAs on components or subsystems (moving down in scale) or on all a corporation’s products (moving up in scale). By analogy with biological ecology, it seems likely that analyses at different scales would ask different questions and reveal different insights...
