Lean Six Sigma Body Of Knowledge For Healthcare Industry Administrators: Implementation Of Lessons Learned In Applied Engineering, Mohammed Ali
Technology Faculty Publications and Presentations
The purpose of this paper is to propose a Lean Six Sigma (LSS) course curriculum for healthcare administration and management majors. It identifies the relevant opportunities and challenges for the application of LSS within the healthcare industry. The paper also discusses the cultural changes necessary to provide an appropriate climate for its long-term success. This work contains a comprehensive description of the body of knowledge in LSS, which were successful in applied engineering. Additionally, the paper describes how LSS may be applied in the hospital setting to improve processes in patient-care services. Upon successful completion of the course, the healthcare …
Design For Waste Reduction And Efficiency Improvement For The Construction Usage Of The Tower Crane, George Merida, Roman Richard
Design For Waste Reduction And Efficiency Improvement For The Construction Usage Of The Tower Crane, George Merida, Roman Richard
Industrial and Manufacturing Engineering
Webcor Concrete Group’s on-site tower crane is currently experiencing unknown forms of inefficiency. The project team used the DMAIC methodology to implement Define, Measure, Analyze, Improve, and Control in order to guide and structure the project. After the project team formulated a problem statement, observations were collected of tower crane deliveries resulting in 470 individual data points. The data was then analyzed using basic statistics, histograms, and lean manufacturing tools in order to identify wastes and inefficiencies. Once the wastes and inefficiencies were identified, root cause analysis was performed. The identified root causes were then used as the basis for …
Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Theses and Dissertations
This thesis presents methods for efficiently controlling a buffer that is located between two non-synchronized manufacturing processes. Several machines with different cycle times and/or batch sizes perform each manufacturing process. The overall operation cycles every T time units. The first objective of the problem is to minimize the average buffer inventory level during one cycle. The second objective is to minimize the maximum inventory level observed at any point during the cycle. This new optimization problem has not been previously considered in the literature. An integer program is developed to model this problem. In addition, two heuristic methods—a simulated annealing …
