LOG 0570 Test Passed Level of Repair Analysis (LORA) Spring 2024 Defense Acquisition University

LOG 0570 Test Passed Level of Repair Analysis (LORA) Spring 2024 Defense Acquisition University LOG 0570 – Level of Repair Analysis (LORA) After an initial Level of Repair Analysis (LORA) is performed, which of the following may necessitate reevaluation of the LORA? (Select three.) • A change to the equipment or major component cost • A change in failure rates • An engineering change or modification to the system design • Entrance into each new production phase Level of Repair Analysis (LORA) addresses the Directive 5000.01 Life Cycle Logistics policy by: • Providing logistics documentation • Minimizing Total Ownership Cost (TOC) • Ensuring multi-functional buy-in • Reducing DoD’s “logistics footprint” Which three statements are true? • Supportability Analysis strives to optimize total system availability while minimizing cost and the logistics footprint • Supportability Analysis includes analyses and procedures that promote supportability as a design characteristic • The Supportability Analysis Product Support Package describes the spares, resources, and other elements that are evaluated by a LORA model • Supportability Analysis is the set of analyses that quantifies a combat unit’s warfighting capability needs Supportability Analysis includes analyses of: (Select three.) • Business Case Analysis (BCA) • Fault Tree Analysis (FTA) • Condition Based Maintenance (CBM) • Reliability and Maintainability (R&M) Which three of the following are sources for Level of Repair Analysis (LORA0 policy guidance? • MIL-HDBK-502A, Product Support Analysis • DoD Directive 5000.01, The Defense Acquisition System • MIL-HDBK-2155, Failure Reporting Analysis and Corrective Action Taken • DoD Instruction 5000.02, Operation of the Defense Acquisition System A poorly executed Maintenance Plan (MP) leads to a chain reaction that can ultimately affect end-item availability. • True • False Total Ownership Cost includes supply chain or business process costs that logically can be attributed to the operation of a system. • True • False The first step in conducting a Level of Repair Analysis (LORA) is: • Select a LORA process • Create a LORA plan • Collect the input data • Document the LORA process conclusions, recommendations, and issues How do Level of Repair (LOR) codes function within the LORA model? (Select three.) • Provides a tool to construct a hypothetical maintenance alternative • Identifies if an item should be discarded after it fails • Shows the repair level or echelon where an item is fixed after it fails • Identifies the failure mode of each spare part What is the primary mission of the Department of Defense (DoD) Acquisition System? • Decrease the reliance on commercial and non-developmental items • Provide the warfighter with affordable, rapidly fielded, sustainable capability • Increase spending in defense procurement appropriations • Develop systems that will increase Foreign Military Sales (FMS) Which of the following statements in true? • LORA addresses corrective and preventive maintenance • LORA addresses neither corrective nor preventive maintenance • LORA addresses preventive maintenance • LORA addresses corrective maintenance Level of Repair Analysis (LORA) does not increase equipment quantity, equipment availability (including reliability), or program capability. • True • False What is the definition of repairables? • Supply items over a certain dollar amount that would be too expensive if identified as consumables • Supply items that can be repaired, but are not repaired, usually due to economic reasons • Supply items that generate requirements for spares • Supply items subject to economical repair and for which the repair is considered in satisfying computer requirements at any inventory level Which of the following are non-economic factors? (Select three.) • Mission criticality • Human safety • Reliability improvement plan • Policy and regulations This type of input data includes number and echelon type, number of operating equipment, and equipment operating hours per month. • Item data • Resource data • Program data • Site data Equipment can be represented by three hardware indentures but are not required to be. One and two indenture representations are also valid. • True • False Improving equipment maintainability: • Reduces failure frequency • Reduces equipment availability • Increases failure duration • Reduces failure duration Capacity = • Quantity x Cost • Total Time x Cost • Quantity x Operational Availability (Ao) • Operational Availability / Quantity A primary LORA objective is to develop and recommend a maintenance scenario that minimizes total ownership costs (TOC). • True • False Which single phrase most accurately describes a primary purpose for conducting an economic LORA? • Maximize equipment capability by increasing maintenance shop time • Minimize total ownership cost by reducing the quantity of weapon systems needed • Minimize life cycle logistics support costs by efficiently allocating maintenance resource and spares • Reduce failure frequencies by increasing reliability
