Logistic Support Analysis (LSA)

 

1. Logistic Support Analysis (LSA)

1) Definition

 

LSA is the activity which checks, defines, analyzes and makes concrete the logistic support elements through the lifecycle of the weapon system, provides the information required to establish the support system of the main equipment in the entire process of the weapon system acquisition management, to optimize the operational cost of the weapon system and utilize the system engineering method for the continuous logistic support in the operation for the ILS task.

 

2) Failure definition / Scoring criteria

 

(1) Definition

It is an activity which define, identify and set up the scoring criteria for the failure affecting the weapon system and is the basis document of the LSA

(2) Role

The purpose of the failure definition / scoring criteria is to provide the credible RAM analysis standard by the approach with the consistent methods and standard to the functions and sub-functions for various tasks required to achieve the variety of mission for the equipment, provides the failure modes for the RAM analysis and FMECA, is used as the basic data for the judgment of the quantity of maintenance labor and writing the technical manual and as the measure for the RAM element analysis evaluation.

3) In Process Review (IPR)

 

(1) Definition

The relevant agency reviews the ILS element development process of the weapon system under the R&D at a suitable time to upgrade the quality of the final product and to lead the optimal ILS element development

4) LCN family tree

 

(1) Definition

The LSA Control Number (LCN) is the code granted to input and output the LSA data processing system and the convenience in the analysis while performing the LSA task and configures the classification system for the items to the tree structure in line with indenture level based on the LCN granted to the item.

(2) Role

The LCN indicates the functional and physical assemble, integration and breakdown procedure for the entire system including the main, supporting and training equipment and is used as a key item for the data input or output through the SOLOMON system.

5) General breakdown list

 

(1) Definition

The General Breakdown List (GBL) is the list of the LSA-related information based on the actual analysis items required for the LSA as a result of the drawing system analysis.

(2) Role

The GBL functionally and physically classifies the top and bottom structures in the weapon system, is the specific list of the item under the analysis which identifies the specific information of the part and provides the LSA, source, Maintenance and Recoverability(SMR) code, non-military code, criticality code, CAGE code, failure rate, MTBF and quantity for the H/W item based on the breakdown drawing of the part for the production.

6) Functional Group Code (FGC)

 

(1) Definition

It is the standard index system which systematically grants the number to break down / set up the component, assembly and part depending on the functional specification of the system.

(2) Role

It provides the standard for the writing order of the technical manual and maintenance allocation chart (MAC) and affects the breakdown order of the system on the maintenance allocation chart. It clarifies the configuration order of the repair parts, list manual on the special parts, maintenance allocation chart and the order of the maintenance manual.

7) Failure Mode, Effects and Criticality Analysis (FMECA)

 

(1) Definition

It defines the failure modes, identifies the effect and quantifies and analyzes the criticality result affected on the equipment and operator in the weapon system.

(2) Role

The FMECA is used to eliminate or minimize the possibility for the failure by identifying the possibility for the critical failure and reflecting on the design.

(3) Related standard / benchmark

MIL-STD-1629A FMECA procedure

 

8) Reliability Centered Maintenance (RCM)

 

(1) Definition

It logically decides the requirement and properness for the preventive maintenance work to prevent the failure based on the previous operation data and the result of the FMECA for the maintenance item and is the process which analyzes the optimal element of the selected preventive maintenance

(2) Role

It identifies the work, type and cycle of the preventive maintenance through the Reliability Centered Maintenance (RCM) analysis to provide the basic data for the technical manual and the configuration for the maintenance level and element

9) Source, Maintenance and Recoverability (SMR)

 

(1) Definition

The Source Maintenance Recoverability (SMR) code identifies the acquisition method, maintenance level selection, recovery or disposal limit for all the items with 5 alphabets and means the supply type, replace level, repair level or recoverability, disposal concept and level for the item as a result of the LSA

10) Maintenance Task Code

 

(1) Definition

It is the package of 6 data elements which uniquely identifies the maintenance task related to the item under the analysis. The first 5 digits provide the information related to the task performance itself and the 2 digits in the last place is the serial code to identify the task of the first 5 digits

(2) Role

- Express the operation / maintenance task for the item
- Fundamental basic data to identify the maintenance task / develop proper maintenance requirement to minimize the maintenance support element
- Consist of 6 codes

11) RAM Matrix

 

(1) Definition

Integrated data for the maintenance task by summarizing the MTBF, MTTR and availability for the item under the analysis

(2) Role

The RAM summary data deduces the maintenance task(planned/unplanned) for the failure mode and works as the fundamental data for the LSA by indicating the work report, required time and reliability of the items under the analysis

12) Maintenance level selection data

 

(1) Definition

It identifies the maintenance man-hour, supply item(repair parts, consumable items, etc.), test equipment and tools for the unscheduled task that is identified as a high safety hazard severity item based on the severity classification and relative critical value of the failure mode identified by the FMECA, and the scheduled task identified by the RCM analysis.

(2) Role

It is the main function of the LSA, determines “Which level performs the maintenance” with the minimum cost considering the logistic support concept after the maintenance identified and provides the logical analysis procedure for the SMR code in the process of judging “Which level performs the repair”
