• Current Conditions
• Analysis
• Justifications
• Final Recommendations

Company Background

• Originally Perry Technologies (founder John
  Perry)
• Invented one of the first submarines
• Lockheed Martin Corporation
• Maritime Systems and Sensors
• Electronic Systems
• Designs and manufactures prototype automated
  underwater vehicles (AUVs)
• Ramping up to production on specific vehicles
• Riviera Beach, FL
• Contact
• Kirsten Goerl

4
Problem Formulation

• Advanced Deployable System
• Array Installation Unit (AIM)
• Dispenser Transport Vehicle (DTV)
• Prototype Construction
• Make it work philosophy
• No set process for production

5
Project Deliverables

• Further define the assembly flow of the build of
  the DTV
• Segment the design into Subassembly and Install
  levels of integration
• Estimate manufacturing hours for assembly of each
  section

6
Current Conditions

• Riviera Beach is adjusting to a production
  environment
• Engineers accustomed to designing prototypes
• Prototype built in an inefficient and time
  consuming manner
• At the time the prototype was built there was no
  defined production process.
• Prototype built using the drawings as a reference
  and a make it work philosophy.
• No set order of installation

7
Analysis

• Production layout determined by the material flow
• Material Control Kitting Dept Production
  Floor
• Order of installation important
• Small radius
• Obstructions
• Example Hub
• Parts/Sections done in parallel
• Forward and Aft Sections

Human Factors

• Anthropometric
• Parts too heavy for average person to lift
• Hands too small to install parts
• Biomechanical
• Sub-assemblies pushed and pulled together
• Technicians backs were a concern
• Physiological
• Lifting parts repetitively affected the
  cardiovascular system
• Psychomotor
• Only diagrams and drawings are used for buildno
  text
• Difficulty identifying some parts
• Environmental
• Large amount of space required due to its size
• Air-conditioned area

14
Justifications

• Technical
• 4600 parts to 1705 parts
• Ergonomic
• Smaller workspace needed
• Less complexity
• Economic
• Labor from 518.5 to 426.4 hours
• Total savings 4,052.40 /vehicle
• Not including part cost reduction

15
Final Recommendations

• Use assembly flow
• Follow schedule
• Use production floor layout
• Consider enforcing safety protocol
• Wear safety glasses in designated areas
• Make steel toe shoes available for all employees
  on production floor
