Size And Cost Reduction Of The Antenna 3000, Mario Mignott, Austin Deaver, Josh Madaris

Senior Design Project For Engineers

For our senior design project, we have partnered with Compass Technology Group to improve its Antenna 3000 manufacturing process. The Antenna we are working on is not actually called this, but due to NDA regulations, we will disguise it as the Antenna 3000. This will include finding a way to minimize material costs and labor hours involved to assemble this product together. Our minimum success criteria will be to reduce both the manufacturing time and materials' cost by 20%. Our primary approach to solving this problem will be to implement Lean Six Sigma practices such as the DMAIC principle.

Throughput And Yield Improvement For A Continuous Discrete-Product Manufacturing System, Md Shahriar J. Hossain

LSU Doctoral Dissertations

A seam-welded steel pipe manufacturing process has mainly four distinct major design and/or operational problems dealing with buffer inventory, cutting tools, pipe sizing and inspection-rework facility. The general objective of this research is to optimally solve these four important problems to improve the throughput and yield of the system at a minimum cost.

The first problem of this research finds the optimal buffer capacity of steel strip coils to minimize the maintenance and downtime related costs. The total cost function for this coil feeding system is formulated as a constrained non-linear programming (NLP) problem which is solved with a search …

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 …

Optimization Of Rfid System Coverage In A Manufacturing Environment, Scott D. Malatesta

Master's Theses

This paper compiles existing ideas, theories, and experiments across multiple disciplines to provide guidance for a company looking to implement an optimal RFID system in their production facility. The desire is to maximize the information received by the system while minimizing the cost. Four potential layouts of RFID antennas, two with overlapping antenna coverage and two with non-overlapping layouts, are first analyzed to understand the special coverage and the number of antennas required. The value of information is then quantified to determine whether higher coverage layouts are worth the additional costs associated with the higher number of antennas required. It …

The Application Of Gage R&R Analysis In S Six Sigma Case Of Improving And Optimizing An Automotive Die Casting Product’S Measurement System, Qizheng Ren

Masters Theses & Specialist Projects

With the rapid development of automation technology in automotive manufacturing processes, massive and efficient production is a current trend. Therefore, measurement systems with accurate and automated measuring instruments are sought by automotive companies and suppliers. However, the problematic measuring instruments with unreliable accuracy and stability lead to erroneous measurements and wrong quality decisions that cause manufacturers huge profit losses. An effective method called “measurement system analysis” can be applied to define and eliminate erroneous measurements to ensure adequate reliability. An automotive transmission die casting parts supplier called company T was suffering a serious profit loss due to the erroneous measurements …

Design For Manufacturing Of Sports Equipment, Cedrick Bit, Christopher L. Head

Industrial and Manufacturing Engineering

The purpose of this project was to validate industrial designs for a product in its conceptual stage and suggest/implement design changes that suit the contracting company’s needs while assuring the product maintains its basic functional requirements. Techniques and methods used to validate the design include 3‐D solid modeling, physical product application using rapid prototyping to produce the product. Methods of design for manufacturing were analyzed in the design. Processes used in the validation and verification of the design include solid modeling design, methods of measurements, fixture design and manufacturing processes. Full design specifications and solid model files were finalized and …
