LOG 1000 – Module 3 – Life Cycle Logistics Fundamentals Knowledge Review Questions Devon needs to match each situation with its appropriate support factor. Reliability Maintainability Other Support Factors Replacing glass with plastic will reduce performance life span Design includes coupling that is easy to access during repairs High grade plastic requires less packing material for transit Design includes coupling that has a 50% greater life span Personnel have experience replacing new exterior panel Proposed coupling uses parts already in inventory New exterior panels have longer time between replacement Replacing plastic will require higher grade repair personnel Use of proposed exterior panel requires new tooling machinery Devon needs to identify which activities fall within each category. Design for Support Design the Support Support the Design Identify capability Perform Maintenance Task Analysis Perform Sustaining Engineering tasks Establish supportability objectives Determine levels of repair Establish technical data needs Perform Functional Analysis Identify likely modes of failure Identify support equipment requirements Devon needs to match the System Operation Area to the appropriate Supportability Expectation. System Operation Area Supportability Expectation Human Capability and Limitations Personnel using the bomber will not likely be in a hazardous or radioactive environment Mission Frequency and Duration The bomber and the accompanying avionics suite will likely be in the air three to four times each week Anticipated Service Life The avionics suite should be functional for at least 4,500 service hours Mobility The bomber will likely be deployed in a theater that is a long distance from supply outposts and allies Deployment The avionics suite will be deployed to a theater that has high temperature variations in a single day

Devon needs to identify the Design Interface activity by phase. Materiel Solution Analysis Technology Maturation and Risk Reduction Engineering and Manufacturing Development Specify measurable support performance requirements Develop a baseline comparison system Draft Product Support Plan Provide procedures to develop supportability assessments Perform trade-off analyses Produce prototypes Design parameters to address operational effectiveness Develop alternative support concepts Assess ability to meet Key Performance Parameters Devon is thinking through the consequences of omitting system design parameters. System Design Parameter Consequences of System Design Parameter Omission Affordability All available funds have been depleted after one year of deployment because the logistics costs were minimized Safety Access to avionics suite can be dangerous due to the proximity to the fuel lines Anti-Tamper The highly sensitive information in the software for the avionics suite was accessed by an unauthorized person Human Factors Engineering The repair personnel have not been trained on how to repair the avionics system Disposal At the end of the life cycle, the software fell into the hands of an adversary Devon has been investing some examples of the benefits of standardizing parts in the avionics suite. Benefit Example Reduce the Variety of Parts The team has worked to redesign the system to use five sizes of composite fastener, instead of seventeen sizes Enhance Interoperability These fasteners have been easier for the repair personnel to replace because fewer changes of tools and required Provide Cost Savings 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 The fasteners have been validated, and have a known life span, resulting in a predictable replacement schedule before breakage. Reduce Acquisition Lead- Time The proposed fasteners have been designed and validated by logistics and do not require the design process.

Devon has identified some examples of problems that can effect specific logistic footprint variables. Variable Example Reliability The system breaks every 25 hours of use, requiring repair Weight During the Analysis of Alternatives, the decision was made to use a denser material for exterior panel Volume Several tooling components must be added, resulting in more repair space required Personnel The average maintenance person does not have the qualifications to repair the new avionics suite Cost The added repair components are in excess of the budget line item allocated for system sustainment Maintainability The avionics suite is placed in such a way that is difficult to access
