Implementation of RFID in a low volume high flexibility assembly plant : item-level tagging
(Massachusetts Institute of Technology, 2010)
The implementation of an RFID checkpoint system in a low volume high flexibility assembly plant, aimed at tracking the flow of parts within the facility, was studied. A pilot revealed the suitability of the technology to ...
Developing an improved production planning method for a machining cell using an active-nondelay hybrid scheduling technique
(Massachusetts Institute of Technology, 2010)
We examine the production planning and scheduling of a job shop environment of a machining cell in a manufacturing facility. This thesis addresses the scheduling limitations in the machining cell that can result in unbalanced ...
Control of WIP and reduction of lead time in a food packaging company
(Massachusetts Institute of Technology, 2010)
High inventory holding costs, strain on warehouse capacity and the competition of lead time are concerns of a food packaging manufacturer. In this work, causes of high WIP were identified and three approaches were developed ...
Statistical control and experimental design for edge bead reduction in laminating process
(Massachusetts Institute of Technology, 2010)
Edge bead formation is a well-known phenomenon typically happening in the lamination due to the physics of this process. It causes the defect of high edge observed in the carton roll after the laminated carton sheets are ...
An optimization grouping method in a multi-line manufacturing system
(Massachusetts Institute of Technology, 2010)
A tailored product grouping method using binary integer linear program for optimization is developed for two production lines in a food packaging manufacturer. A mathematical model is created to assign products to the two ...
Assembly cell layout and Kanban system design for an oilfield services company
(Massachusetts Institute of Technology, 2010)
The thesis describes the layout design of new gauge assembly lab for an oilfield services company. A relationship diagram was created to categorize all the workstations and activities in the assembly line. Three layouts ...
An application of Value Stream Mapping to reduce lead time and WIP in a make-to-order manufacturing line
(Massachusetts Institute of Technology, 2010)
Significant growth in the sales is expected in the coming years for the product family that is the focus of this research. In order to meet the takt time for the future demand, improvement on the current processes and ...
Implementation of RFID in a low volume high flexibility assembly plant : process redesign
(Massachusetts Institute of Technology, 2010)
This thesis focuses on the operational improvements in a semiconductor equipment manufacturing company (Varian Semiconductor Equipment Associates). The company faces challenges of highly fluctuating demand as well as complex ...
Quality improvement and control based on defect reduction
(Massachusetts Institute of Technology, 2010)
This thesis addresses the quality improvement in a printing process at a food packaging company now experiencing hundreds of printing defects. Methodologies of Define, Measure, Analyze, Improve, and Control (DMAIC), and ...
Implementation of RFID in a low volume high flexibility assembly plant : module component tracking
(Massachusetts Institute of Technology, 2010)
The purpose of this thesis is to help Varian Semiconductor Equipment Associates, Inc. (VSEA) to smooth the production and reduce the manufacturing cost. Without an efficient way to track on its high-value components, VSEA ...
