Learning Curve Analysis Using Intensive Longitudinal And Cluster-Correlated Data, Xiao Zhong, Zeyi Sun, Haoyi Xiong, Neil Heffernan, Md Monirul Islam Jun 2018

Learning Curve Analysis Using Intensive Longitudinal And Cluster-Correlated Data, Xiao Zhong, Zeyi Sun, Haoyi Xiong, Neil Heffernan, Md Monirul Islam

Zeyi Sun

Intensive longitudinal and cluster-correlated data (ILCCD) can be generated in any situation where numerical or categorical characteristics of multiple individuals or study units are observed and measured at tens, hundreds, or thousands of occasions. The spacing of measurements in time for each individual can be regular or irregular, fixed or random, and the number of characteristics measured at each occasion may be few or many. Such data can also arise in situations involving continuous-time measurements of recurrent events. Generalized linear models (GLMs) are usually considered for the analysis of correlated non-normal data, while multivariate analysis of variance (MANOVA) is another ...


Lean Adoption In A Small And Medium Enterprise: Model Validation, Kimberly Deranek, Shweta Chopra, Gretchen A. Mosher Nov 2017

Lean Adoption In A Small And Medium Enterprise: Model Validation, Kimberly Deranek, Shweta Chopra, Gretchen A. Mosher

Shweta Chopra

Globally, numerous manufacturing and service organizations are incorporating lean techniques to identify waste, eliminate non-value-added activities, and increase efficiency. Some small and medium sized enterprises (SMEs) have also incorporated lean principles, yet others remain laggards. There is evidence that suggests if critical success factors (CSFs) exist in SMEs, there is a higher probability of the successful implementation of lean practices. Using a case study approach regarding the successful adoption of lean practices within a SME, this paper validated and tested the credibility of a CSF model. During a 12-month consulting arrangement, the research team used formal and informal observations and ...

Usage Analysis Of Milwaukee County's Paratransit System: The Case Of Potawatomi Casino And Veteran Affairs Medical Center Destinations, Po-Hsueh Chiu Aug 2015

Usage Analysis Of Milwaukee County's Paratransit System: The Case Of Potawatomi Casino And Veteran Affairs Medical Center Destinations, Po-Hsueh Chiu

Theses and Dissertations

In order to protect the rights of seniors and Persons with Disabilities (PWDs), the United States government, through Congress, enacted the Americans with Disabilities Act (ADA) in 1990. The Act ensures that there is equity for persons with disabilities in all aspects of public services including employment, education, transportation, accommodation, commercial facilities and businesses and communication (Federal Register, 2010). In this study, we focus on the problem of transportation of PWDs, specifically in Milwaukee County in Southeast Wisconsin. The study was initiated as a collaborative effort between UWM’s Industrial and Manufacturing Engineering team, UWM’s Director of the Rehabilitation ...


Manufacturing Execution System (Mes) An Examination Of Implementation Strategy, Riley F. Elliott Jun 2013

Manufacturing Execution System (Mes) An Examination Of Implementation Strategy, Riley F. Elliott

Master's Theses and Project Reports

The priorities of executing the manufacturing orders generated by an MRP system are often in operational conflicts with the dynamics of the manufacturing floor. It is not uncommon for a given manufacturing order to reach the shop floor several weeks or longer after being "opened" by an MRP system where it may face a chaotic case of large queues, machine down-time, parts shortage, scrap problems and other resource management constraints. Many companies have resorted to the Manufacturing Execution System (MES) software solution to resolve these problems. This method first gained popularity in mid-90’s within the semiconductor industry. An MES ...


Simulation Modeling For Integrated E-Supply Chain Management, Pornsarun Wirojanagud May 2001

Simulation Modeling For Integrated E-Supply Chain Management, Pornsarun Wirojanagud

Theses

E-supply chain management is an emerging area of interest as companies begin to explore the Internet's potential to restructure supply chain relationships. The environmental impact of e-supply chain management is a critical issue towards sustainability. This thesis discusses and models an integrated e-supply chain network accounting for material and information flows throughout the supply chain in order to analyze the environmental implications and tradeoffis with other system characteristics. The network structure has complex interactions between various entities. In order to understand and analyze dynamic performance, a discrete-event simulation approach is utilized. An integrated tool was developed using the Arena ...

A literature review was conducted to identify some of the requirements for competitiveness and change that are being promoted by leaders in the manufacturing field. A survey was developed based on the literature review and was subsequently administered, via the case study method, at a midwestern US agricultural chemicals firm to determine the company's degree of compliance with the literature''s recommendations. To a large degree, the company complied with the requirements.
