Life Cycle Logistics Fundamentals (Module 3)

Life Cycle Logistics Fundamentals (Module 3) Reliability Ans- -New exterior panels have longer time between replacement -Replacing glass with plastic will reduce performance life span -Design includes coupling that has a 50% greater life span Maintainability Ans- -Replacing plastic will require higher grade repair personnel -Design includes coupling that is easy to access during repairs -Personnel have experience replacing new exterior panel Other Support Factors Ans- -High grade plastic requires less packing material for transit -Use of proposed exterior panel requires new tooling machinery -Proposed coupling uses parts already in inventory Design for Support Ans- -Establish supportability objectives -Perform Functional Analysis -Identify capability Design the Support Ans- -Determine levels of repair -Perform Maintenance Task Analysis -Identify likely modes of failure Support the Design Ans- -Perform Sustaining Engineering tasks -Establish technical data needs -Identify support equipment requirements Human Capability and Limitations Ans- Personnel using the bomber will not likely be in a hazardous or radioactive environment Deployment Ans- The avionics suite will be deployed to a theater that has high temperature variations in a single day Anticipated Service Life Ans- The avionics suite should be functional for at least 4,500 service hours Mobility Ans- The bomber will likely be deployed in a theater that is a long distance from supply outposts and allies Mission Frequency and Duration Ans- The bomber and the accompanying avionics suite will likely be in the air three to four times each week Materiel Solution Analysis Ans- -Specify measurable support performance requirements -Provide procedures to develop supportability assessments -Design parameters to address operational effectiveness Technology Maturation and Risk Reduction Ans- -Develop a baseline comparison system -Perform trade-off analyses -Develop alternative support concepts Engineering and Manufacturing Development Ans- -Draft Product Support Plan -Produce prototypes -Assess ability to meet Key Performance Parameters Affordability Ans- All available funds have been depleted after one year of deployment because the logistics costs were minimized Safety Ans- Access to avionics suite can be dangerous due to the proximity to the fuel lines Anti-Tamper Ans- The highly sensitive information in the software for the avionics suite was accessed by an unauthorized person Human Factors Engineering Ans- The repair personnel have not been trained on how to repair the avionics system Disposal Ans- At the end of the life cycle, the software fell into the hands of an adversary Provide Cost Savings Ans- Five lots of 10,000 fasteners were purchased, instead of seventeen lots of 3,000. The price per item was renegotiated. Promote Reliability and Safety Ans- The fasteners have been validated, and have a known life span, resulting in a predictable replacement schedule before breakage. Reduce Acquisition Lead-Time Ans- The proposed fasteners have been designed and validated by logistics and do not require the design process. Reduce the Variety of Parts Ans- The team has worked to redesign the system to use five sizes of composite fastener, instead of seventeen sizes. Enhance Interoperability Ans- These fasteners have been easier for the repair personnel to replace because fewer changes of tools are required. Reliability Ans- The system breaks every 25 hours of use, requiring repair Weight Ans- During the Analysis of Alternatives, the decision was made to use a denser material for exterior panel Volume Ans- Several new tooling components must be added, resulting in more repair space required Personnel Ans- The average maintenance person does not have the qualifications to repair the new avionics suite Cost Ans- The added repair components are in excess of the budget line item allocated for system sustainment Maintainability Ans- The avionics suite is placed in such a way that it is difficult to access Choose the correct definition of the logistics measure of weight: Ans- Total tonnage of deployable consumables, support equipment, energy (fuel, oil, etc.), and spares Using the Affordable System Operational Effectiveness chart (page 3 of 12) Select the design components that promote supportability: (Select all that apply.) Ans- -Reliability -Maintainability Supportability factors include: Ans- The more reliable and maintainable the system is, the less support it will require once it is fielded. The primary objective is to reduce the need for logistics support after a weapon system is fielded. The system design parameter of System Safety: Ans- Addresses risks to personnel and equipment Select the true statement about Parts Standardization. Ans- Parts standardization seeks to use existing parts and equipment rather than designing, developing, and producing new parts. Select all responses that are true about logistics footprint: Ans- -The logistics footprint is the size or "presence" of logistics support required to deploy, sustain, and move a weapon system -A large logistics footprint can adversely affect a rapid deployment and its sustainability -The logistics footprint includes personnel, supplies/equipment, land, and facilities necessary to deploy and sustain a weapon system Choose the correct purpose of Design Interface: Ans- Ensures that logistics support considerations are part of the design process and that the system design is fully supported by the Integrated Product Support elements Parts standardization reduces costs and improves asset availability due to: 1. Enhanced interchangeability, reliability, and availability of parts 2. Reduced proliferation of parts and drawings 3. Diminished single source impacts and parts obsolescence 4. Promotion of commonly used industry parts Ans- All of the choices are correct
