Theory And Practice Of Supply Chain Synchronization, Michael Prokle Nov 2017

Theory And Practice Of Supply Chain Synchronization, Michael Prokle

Doctoral Dissertations

In this dissertation, we develop strategies to synchronize component procurement in assemble-to-order (ATO) production and overhaul operations. We focus on the high-tech and mass customization industries which are not only considered to be very important to create or keep U.S. manufacturing jobs, but also suffer most from component inventory burden. In the second chapter, we address the deterministic joint replenishment inventory problem with batch size constraints (JRPB). We characterize system regeneration points, derive a closed-form expression of the average product inventory, and formulate the problem of finding the optimal joint reorder interval to minimize inventory and ordering costs per unit …


Design The Capacity Of Onsite Generation System With Renewable Sources For Manufacturing Plant, Xiao Zhong, Md Monirul Islam, Haoyi Xiong, Zeyi Sun Nov 2017

Design The Capacity Of Onsite Generation System With Renewable Sources For Manufacturing Plant, Xiao Zhong, Md Monirul Islam, Haoyi Xiong, Zeyi Sun

Computer Science Faculty Research & Creative Works

The utilization of onsite generation system with renewable sources in manufacturing plants plays a critical role in improving the resilience, enhancing the sustainability, and bettering the cost effectiveness for manufacturers. When designing the capacity of onsite generation system, the manufacturing energy load needs to be met and the cost for building and operating such onsite system with renewable sources are two critical factors need to be carefully quantified. Due to the randomness of machine failures and the variation of local weather, it is challenging to determine the energy load and onsite generation supply at different time periods. In this paper, …


Life Cycle Sustainability Analysis (Lcsa) Of Polymer-Based Piping For Plumbing Applications, Andy J. Rivas Bolivar May 2017

Life Cycle Sustainability Analysis (Lcsa) Of Polymer-Based Piping For Plumbing Applications, Andy J. Rivas Bolivar

Senior Honors Projects, 2010-2019

Water conveyance systems play a critical role in modern developed areas. Polymer pipes have been used for about a century, and their convenient physical properties have positioned polymers as the leading material in the piping industry. Having such influence in the market means that changes in current material selection and manufacturing could lead to significant reductions in the footprint associated with their products. Currently, there are no comparative lifecycle assessments that evaluate the different polymer selections commercially available, which makes it hard to determine what products have the least impact on the environment. Understanding how such impacts are relative to …


A Study Into The Production Efficiency Of Cal Poly Chocolates, Fernando Calderon Mar 2017

A Study Into The Production Efficiency Of Cal Poly Chocolates, Fernando Calderon

Industrial and Manufacturing Engineering

The project objective was to: identify ways to reduce the production cost of Cal Poly Chocolates. The project was executed through the DMAIC approach, a data driven improvement cycle. Using several industrial engineering tools, six improvement opportunities were found. Three project deliverables were created and three process changes were recommended. The total annual savings, if recommendations are implemented, sum to $1700.
