Functional Analysis & Allocation Report for Preliminary Design

This report provides a comprehensive review of the Functional Analysis & Allocation (FA&A) process within the preliminary design stage of systems engineering. It explores the purpose, inputs, outputs, staging, and supporting processes of FA&A, emphasizing its role in translating system-level requirements into detailed functional and performance design principles. The report discusses various approaches and methods for functional analysis, including Functional Flow Block Diagrams and functional trees, and functional allocation. A case study is presented to illustrate the application of FA&A in analyzing the requirements for light railway systems, focusing on the challenges and improvements related to level crossings. The report also covers methods for functional allocation, outlining how functions are assigned to system components and the technical bases for allocation decisions, along with the importance of operational experience in refining functional allocations. The report is based on the course materials, textbook, and tutorial solutions.
