Heuristic Solution For Separated Manufacturing Process, James Dee Davis
Heuristic Solution For Separated Manufacturing Process, James Dee Davis
Masters Theses
Downtime is a major issue for manufactures. Downtime may occur from breakdowns, quality issues, lack of manpower, lack of materials, or in this case a lack of storage containers. A manufacturing system was studied that consists of an injection machine that supplies two assembly lines. The injection machine suffered from frequent downtime from lack of containers. The process was analyzed for root cause of downtime. After analysis of the system it was found that the injection process had high variability in production quantity and quality. The scheduling scheme called for production until all available containers were full regardless of actual …
A Lean Information Management Model For Efficient Operations Of An Educational Entity At The University Of Tennessee, Harshitha Muppaneni
A Lean Information Management Model For Efficient Operations Of An Educational Entity At The University Of Tennessee, Harshitha Muppaneni
Masters Theses
A software based Management Information System (MIS) is designed and implemented in the Department of Industrial and Systems Engineering at University of Tennessee to handle different types of data requests that are currently processed through multiple steps. This thesis addresses the current resource intensive data management model in educational institutions and proposes a decentralized and customized solution. The proposed software based data management system provides information to authorized sources in the requested format with minimal or no time consumption. The quantification of the new systems’ impact is done by comparing it with current data management process using Graph Theoretic Approach …
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 …
