Bikeshare Business Model For Cal Poly- San Luis Obispo, Justin Benson, Andrew Neil Gatchalian

Industrial and Manufacturing Engineering

With the increasing admittance of students into colleges and universities across the nation, the need for alternate modes of transportation is becoming more pressing. College and university campuses, as well as small cities, in which there is a college or university, are being overloaded with student cars. In San Luis Obispo specifically, parking on campus as well as downtown can be extremely difficult to find. Traffic is also getting progressively worse, especially at the hour when class begins/ends and student arrive to or leave campus. Financial reasons are yet another deterrent for students at Cal Poly. Parking permits, gas, and …

Redesign Of Talley Farm's "Fresh Harvest" Produce Program, Nicole Bordwell, John Rivera, Jared Toboni

Industrial and Manufacturing Engineering

Fresh Harvest, a Central Coast Community Supported Agriculture (CSA) program run by Talley Farms located in Arroyo Grande, CA, has a rapidly growing customer base. They harvest, package, and deliver boxes of fresh quality produce to almost 3000 subscribers. However, Talley Farms’ space for production and processing is limited and at times required for other aspects of business. This results in a problem where Talley Farms current processing system of produce for the Fresh Harvest program is not suitable for the forecasted growing demand. This report addresses the need to prepare for continued significant growth to the demand for Fresh …

Process Improvements Of Cilantro Harvesting With Ergonomic Considerations, Eric Penningroth, Branden Shimamoto

Industrial and Manufacturing Engineering

The problems presented by Talley Farms to the team were a lower than desired cilantro harvesting capacity and work health pertaining to lower back problems. The project objectives were to address and improve upon both of these objectives. To increase harvesting capacity, a simulation model was created using standard times from time studies. The simulation model helped to compare the different harvesting methods as well as the effect of the utilization of the on-site manager. The throughputs between each of the models were analyzed. To address ergonomic concerns, a work sampling study was conducted and it was determined that kneeling …

Effects Of Patient Factors On Implantation Rates In In Vitro Fertilization, Heidi Richardson, Sofia Soto

Industrial and Manufacturing Engineering

The purpose of this report is to evaluate the effects of patient factors and embryo quality on the implantation rate in In Vitro Fertilization (IVF). For this report, statistical methods are used to test the significance of several patient and embryo characteristics on embryo implantation rate. This project is an analysis of data collected from over 36,000 patients.

The analysis concluded several findings. There was enough statistical evidence to conclude that age was significant in regards to implantation rate and FSH levels. As the patient ages, the amount of FSH levels found in their blood increases. A patient with high …

Analysis And Improvement Of The Security Building At Pg&E Diablo Canyon Nuclear Power Plant, Alyssa Carter, Natalie Christa, Phuong Anh Pham Dinh

Industrial and Manufacturing Engineering

A new Security building was recently designed and built at the Pacific Gas and Electric (PG&E) Diablo Canyon Power Plant (DCPP).This building’s staff and equipment are responsible for performing routine inspections on all personnel entering the facility in order to prevent security-related incidents from occurring at the nuclear power plant. Similar to airport security procedures, the DCPP security building routine inspections include the use of x-ray machines, metal detectors, and explosive detectors.

The Power Plant periodically experiences pre-planned, preventive maintenance outages, that last 4-6 weeks. During an outage, a power plant reactor is shut down for maintenance, repair, and re-fueling. …

A Control-Chart Based Method For Solder Joint Crack Detection, Jianbiao Pan

Industrial and Manufacturing Engineering

Many researchers have used different failure criteria in published solder joint reliability studies. Since the reported timeto-failure would be different if different failure criteria were used, it would be difficult to compare the reported reliability life of solder joints from one study to another. The purpose of this study is to evaluate the effect of failure criteria on the reported thermal fatigue life and determine which failure criterion could detect failure sooner. First, the application of the control-chart-based method in a thermal cycling reliability study is described. The reported time-to-failure data were then compared based on four different failure criteria: …

Design Of Transportation Process For Band Equipment, Marissa N. Blustein, Chris M. Kaye

Industrial and Manufacturing Engineering

The following report documents the attempt to design a safe and reliable process for transporting Louder Space’s musical gear that requires minimal physical demand. Design specifications were derived from customer requirements as well as human factors principles. The transportation process was broken down into systematic process steps and standardized, making use of lean methodologies in order to reduce the number of non-value steps involved. Furthermore, a model portable storage unit for miscellaneous gear was developed to the specifications determined by the band using 3D modeling, as well as certain limiting constraints. Once the customer approved the prototype, the product was …

A Control-Chart Based Method For Solder Joint Crack Detection - Conference Proceeding, Jianbiao Pan

Industrial and Manufacturing Engineering

Many researchers have used different failure criteria in the published solder joint reliability studies. Since the reported time-to-failure would be different if different failure criteria were used, it would be difficult to compare the reported reliability life of solder joints from one study to another. The purpose of this study is to evaluate the effect of failure criteria on the reported thermal fatigue life and find out which failure criterion can detect failure sooner. First, the application of the control-chart based method in a thermal cycling reliability study is described. The reported time-to-failure data were then compared based on four …
