Applying Value-Focused Thinking (VFT) and Analytical Hierarchy Process (AHP) to Determine the Authority for Rig-Owned Transportation Management at PT Pertamina Hulu Rokan Zone 4

This study aims to identify the appropriate authority responsible for managing rig-owned transportation within Pertamina Hulu Rokan Zone 4 by employing mixed-method approach, integrating both qualitative and quantitative methodologies. Value-Focused Thinking (VFT) generates values, alternatives, and objectives. Analytical Hierarchy Process (AHP) quantifies and prioritizes criteria and alternatives. VFT, through expert interviews, enhances the initial set of criteria and alternatives by introducing additional sub-criteria and alternatives. AHP is then employed to prioritize the outputs from VFT through a structured computational process. Ultimately, the selected authority established a new operation support function, which is preferred over the existing SCM-RAM system and the Well Intervention (self-managed) alternative
