Abstract

This master’s thesis develops a decision-support tool (DSS) for prioritizing investments in port infrastructure, applied to the ports of the South Aegean Region (Greece). The framework addresses the specific challenges of insularity, strong seasonality and geographic dispersion, where service reliability depends not only on demand levels but also on the technical availability of port assets. The methodology integrates (a) a capital-based assessment of investment needs at port and port-authority level, (b) two capital-intensity indicators—Indicator I (€/IMMs) linked to passenger traffic and Indicator II (€/tn) linked to freight volumes—and (c) a structured technical diagnosis through risk drivers (K1–K6) capturing key constraints such as berthing/Ro‑Ro systems, navigability and depths, harbour protection, structural condition, and landside functional capacity and conflicts of use. Building on these drivers, a Technical Risk Footprint (TRF) is applied as a qualitative vulnerability filter per port authority, enabling Indicators I–II to be interpreted through the lens of safety and operational continuity. Results are synthesized via clustering that jointly considers the indicators I, II and TRF, while a hub–spoke intra-analysis is used for heterogeneous multi-port authorities to distinguish hub ports from secondary ports. The application indicates that effective prioritization should follow staged intervention bundles: safety and continuity first, then operational optimization, rehabilitation/resilience, and finally targeted capacity upgrades, complemented by low-cost organizational measures for flow and landside management. The tool provides a consistent basis for documenting priorities and comparing alternative intervention packages.
