Model For Prioritization Of High Variation Elements In Discrete Production Systems, Bharadwaj Venkatesan
Doctoral Dissertations
The complexity of the modern manufacturing enterprise has led companies to look for techniques and methodologies for improving production performance. Lean manufacturing techniques have been applied in the US with varying degrees of success, and Theory of Constraints (TOC) has been used to emphasize the flow of production and identify performance improvement projects. One aspect of manufacturing for which there has been limited academic or industrial research till date is the impact of variation on production performance and the identification of improvement projects based on variation. This thesis develops a methodology to incorporate random and simultaneous occurrence of variability in …

Astaxanthin, the “king of carotenoids” has been widely used as an animal feed additive for several decades, mainly in the aquaculture industry. Recent studies have led to its emergence as a potent antioxidant available for human consumption. Traditionally it has been chemically synthesized, but the recent market interest has generated interests in producing it naturally via yeast (Phaffia rhodozyma) fermentation, or algal (Haematococcus pluvialis) induction. This work aims to compare these production processes and their impact on the economical, environmental, and societal scale. We also look at the attempts of increasing production yields by altering various …
Interaction Between Primary Resources And Root Causes In Lean Production Systems, Ernest Anene Iwuchukwu
Interaction Between Primary Resources And Root Causes In Lean Production Systems, Ernest Anene Iwuchukwu
Masters Theses
A model to analyze lean systems reliability is developed based on the premises that lean production systems require four primary resources; materials, equipment, personnel, and schedule (Sawhney, R., Subburaman, K., Sonntag, C., Capizzi, C. and Rao, P.V., 2009). The four primary lean resources were independently analyzed, without due consideration to underlying relationships within each other. In this research, relationships and interaction between root-causes and lean primary resources were conceptualized and developed. The development applied a five-phase approach: 1. review of related literature, 2. decompositions of lean primary resources, 3. selection of consensus root causes items and questionnaire construct, 4. survey …
