Swerve, Kaitlin A. Castillo, Cichasky A. Catherine

Industrial and Manufacturing Engineering

Carpooling yields great benefits environmentally, socially, and economically for carpooling, however there is no easy to use, safe, and enjoyable application for people to connect with others who are both close in proximity and have schedules that match currently. By creating a database and visual mock ups, our senior project creates the basis for an application called Swerve that matches users by location and schedules and has social and economic incentives. Our research allowed us to further understand the social, environmental and economic benefits and incentives of carpooling. We also looked into current carpooling websites and applications and could not …

Cost-Based Decision Making Model For Regional In-House Versus Outsourcing Logistics, Henrik Darren Lee Dec 2015

Cost-Based Decision Making Model For Regional In-House Versus Outsourcing Logistics, Henrik Darren Lee

Master's Theses

This thesis proposes a model for selecting between insourcing logistics for local distribution and outsourcing these functions to a third-party logistics (3PL) company. Supply chain optimization, as well as global supply chain management, are topics that are now well-covered; local distribution, despite its integral function in an organization, is much less researched. Models exist for network design and optimization, but the practical application of these network models may call for decisions and considerations that are not covered in these optimization models.

A breakeven analysis selection model between using in-house logistic system and 3PL is derived, considering various regional parameters. The …

Ergonomics Analysis Of Touchscreen Utilization As A Function Of Preferred Hand And Gender, Jordan E. Odell Dec 2015

Ergonomics Analysis Of Touchscreen Utilization As A Function Of Preferred Hand And Gender, Jordan E. Odell

Master's Theses

The growth of touchscreen technology has changed the way users interface with a wide range of computing and communication products and systems. Examples range from personal tablets and laptops to industrial applications such as process control, point-of-sales, and ticketing kiosk systems. An important area of application is the automobile industry which is designing cars with touchscreen control panels to replace the previously designed mechanical knobs and buttons. However, interacting with touchscreens does not provide the same tactile feedback as physical mechanisms, therefore they require more precise movement and visual attention, which distracts the user from the primary task.

The purpose …

Creation And Analysis Of Checklists To Improve Raquet Stringing Performance In Tennis Warehouse, Alston S. Nguyen

Industrial and Manufacturing Engineering

Tennis Warehouse has a need to increase the supply of strung racquets and man hours to complete these strung racquets over the course of a year. That is, the demand can be increased by up to 4 times its average load during certain hectic parts of the year (professional tournaments, holidays, and competitive seasons). Not meeting this demand can lead to upset customers, unnecessary waste and replacing of rushed items and shipping costs, and a discouraged customer service representative workforce. The objective of this project is to use a set of checklists to address this problem and attempt to increase …

The Influence Of Cu3(Btc)2 Metal Organic Framework On The Permeability And Perm-Selectivity Of Plla-Mof Mixed Matrix Membranes, Ajay Kathuria, Saleh Al-Ghamdi, Mohamad G. Abiad, Rafael Auras

Industrial Technology and Packaging

Poly(l-lactic acid) (PLLA) - 20% (w/w) and Cu3(BTC)2 metal organic framework (MOF) based mixed matrix membranes (MMMs) were fabricated by a vertical corotating twin screw microcompounder followed by an injection molding process. Water vapor, CO2, O2, and selected aroma mass transfer properties of PLLA and PLLA MMMs were evaluated. The CO2/O2 perm-selectivity of PLLA (αCO2/O2) MMMs increased from 7.6 to 10.3 with the incorporation of 20% Cu3(BTC)2 MOF. Gravimetric permeability studies of trans-2-hexenal performed at 23°C and 50% RH indicated that permeability coefficient of PLLA MMMs …

Cost Effective Analysis Of Big Data, Steven J. Litzsinger, Nehad Dababo Jun 2015

Cost Effective Analysis Of Big Data, Steven J. Litzsinger, Nehad Dababo

Industrial and Manufacturing Engineering

Executive Summary

Big data is everywhere and businesses that can access and analyze it have a huge advantage over those who can’t. One option for leveraging big data to make more informed decisions is to hire a big data consulting company to take over the entire project. This method requires the least effort, but is also the least cost effective. The problem is that the know-how for starting a big data project is not commonly known and the consulting alternative is not very cost effective. This creates the need for a cost effective approach that businesses can use to start …

Tesla Motors Quality Engineering Application And Implementation, Nick Kwan

Industrial and Manufacturing Engineering

Tesla Motors, in Winter 2013 during the author’s coop,had a variety of potential improvement areas regarding their quality engineering team. There were too many overall defects on the vehicles. Those defects were recognized as the cars were passing through inspection, coming off the line, as well as brought by customers to after-purchase service. One of the defects was the Charge-port Door Malfunction, in which the door of the Model S would not open on command. An additional defect was the Windshield Wiper Malfunction, in which the fluid was not hitting the car at the desired angle. Both of these defects …

Strasbaugh Nonconforming Report Optimization, Eden Andersen, Angela Asgekar, Rebecca Gregg

Industrial and Manufacturing Engineering

This paper strives to convey the problems and proposed solutions for Strasbaugh’s Nonconforming Report (NCR) Optimization. Strasbaugh is a world leader in silicon wafer polisher and grinder technologies. After a significant down size to the company parts they used to manufacture now have to be purchased, and many of these incoming parts do not conform to Strasbaugh’s high standards. This has led to an increase in NCRs that need to be processed, which takes up time, resources and money.

The objective therefore became to update the multi-sheet carbon copy paper system to better optimize the use of these reports and …


Warpage And Shape Distortion In Laser Metal Sintering, Xuan Wang May 2015

Warpage And Shape Distortion In Laser Metal Sintering, Xuan Wang

Industrial and Manufacturing Engineering

Selective Laser Sintering (SLS) is the primary method to fabricate metal and ceramic components in additive manufacturing. Due to the anisotropy of powder material, the sintering rate difference will inevitably causes shape change, distortion , and other defects of sintered parts. In this paper, a continuum model was developed to simulate the SLS process. The developed model has been successful to predict sintering kinetics. The impact of processing parameters, such as laser power, scanning speed, hatching distance, and particle size has been studied . The proposed method provides an innovative tool to optimize SLS process parameters.
