Reliability analysis and design considering disjoint active failure regions
(Wichita State University, 2016-05)Failure of practical engineering systems could be induced by several correlated failure modes, and consequently reliability analysis are conducted with multiple disjoint failure regions in the system random input space. ... -
Reliability assessment and an optimization approach of global supply chain system
(Wichita State University, 2017-05)Due to global outsourcing, supply chain system has become more complex and has faced high risks and disruptions. Many of the disruptions can occur at any time or any stage in the supply chain. Nowadays, businesses and ... -
Repeatability and reproducibility studies: a comparison of techniques
(Wichita State University, 2010-12)Gage Repeatability & Reproducibility (GRR) Studies have become critical in process improvement projects in the manufacturing sectors. There are various methods to conduct GRR study. However, the most widely used is the ... -
A revenue management framework for appointment allocation in rehabilitation outpatient clinics
(2005-12)Rehabilitation outpatient clinics help patients overcome physical disabilities through various rehabilitation services. Appointment scheduling and accepting new patients are very important processes in rehabilitation ... -
Risk based worker allocation and line balancing
(Wichita State University, 2010-12)In general, manufacturing systems could be classified into machine intensive manufacturing and labor intensive manufacturing. From the previous studies, we can infer that worker allocation plays an important role in ... -
Risk oriented stochastic assembly line balancing
(Wichita State University, 2010-08)In a single model manual assembly line, product flows through series of workstations arranged in a sequential manner. Each workstation has a finite number of tasks and each task has probabilistic processing time. Due to ... -
Robot path planning with sensor feedback for industrial applications
(Wichita State University, 2021-05)The research goal of this study is to investigate the use of sensor feedback for robot path planning and optimization. Robots are ideal automation tools for handling highly repetitive manufacturing tasks with unparalleled ... -
Robotic refill friction stir spot welding for aerospace applications
(Wichita State University, 2021-12)The consumption of high-strength aluminum alloys in aerospace industries is increasing and refill friction stir spot welding is found to be a suitable joining technology for aerospace aluminum alloys. Currently, aerospace ... -
Rolling pattern and energy requirements when rolling from supine to side-lying on rigid and soft surfaces
(Wichita State University, 2017-12)Rolling is an activity that most people perform repeatedly on a daily basis. Rolling and repositioning oneself in bed serves to improve comfort, circulation, and sleep quality and prevent decubitus ulcers, commonly referred ... -
Rough set Kansei engineering: multiple users, multiple Kanseis
(Wichita State University, 2010-12)The method proposed in this dissertation addresses the need to relate product features to customer expectations. This is particularly difficult given the variety of consumer perspectives and the uncertainty in their ... -
A sequential Bayesian cumulative conformance control chart for high yield processes
(Wichita State University, 2009-05)For mass production, the traditional approach of drawing the confidence limits was satisfactory when many bad units were being produced; however, the same approach becomes ineffective for high yield processes, when the ... -
Setup approval and self starting schemes for short production runs
(2005-12)A number of approaches have been proposed for applying statistical process control in short production runs. However little has been done to provide a methodology to compare and select from various statistical process ... -
Solution to large facility layout problems using group technology
(2007-05)In this work, a systematic methodology to construct cellular layouts using GT technique for large size problems has been developed. Previous researches in this field have addressed heuristics that can be used to solve only ... -
Solutions to dynamic facility layout problems: Development of Dynamic From Between Chart (DFBC) and its applications to continuous layout modeling
(Wichita State University, 2007-12)Manufacturing facility layout is determined by minimizing the Material Handling (MH) cost associated with the manufacturing of products. A manufacturing facility operates in a dynamic environment where the production rates ... -
Sources of error in relating nanoindentation results to material properties
(Wichita State University, 2010-05)This dissertation consists of four submission-ready papers that address some of the key error sources that affect the accuracy of interpretation of nanoindentation test results to obtain material properties for ... -
Static test simulation of refill friction stir spot welded and riveted coupons using finite element analysis
(Wichita State University, 2019-12)Refill Friction stir spot welding (RFSSW) produces a solid-state lap joint between sheet metals, preferably aluminum alloys, without leaving behind an exit hole in the workpiece. This joining technique was derived from ... -
Statistical comparison of customized and traditional knee implants using Finite Element Analyses
(Wichita State University, 2007-07)According to the National Center for Health Statistics in 2004 over 478,000 people Underwent Total Knee Replacement surgeries in 2004. The number is rapidly growing due to advances in implant surgeries, knee implants, and ... -
Statistical process control implementations within the aviation industry
(Wichita State University, 2021-07)In 1931, Walter Shewhart introduced his work in statistical process control (SPC) through his book, Economic Control of Quality of Manufactured Product. A common confusion in the use of SPC is that it does not fit every ... -
Study of the impact of safety stock placement on shifting bottleneck stages in capacitated supply chains.
(Wichita State University, 2009-05)Uncertainty in a modern supply chain structure originates at the supplier, manufacturing process and the consumer. Different types of products and supply chain structures add to the complexity of managing a supply chain. ... -
