Integration of MOST and TOPSIS Methods to Support Business Development Strategy Formulation in the Steel Pipe Industry of Surabaya, Indonesia

Abstract

This study develops an integrated decision-making framework to formulate business development strategies for the steel pipe manufacturing industry in Surabaya, Indonesia. The research combines the MOST and TOPSIS methods, supported by the Analytical Hierarchy Process (AHP), to systematically identify, evaluate, and prioritize strategic alternatives. Primary data were collected through expert interviews, focus group discussions, and questionnaires, while secondary data were obtained from industrial reports and publications. The analysis identifies five strategic alternatives derived from the MOST framework and evaluates them using AHP–TOPSIS integration. The results show that investment in production technology and automation ranks as the highest-priority strategy, followed by the development of export-oriented marketing channels and enhancement of quality management systems. Sensitivity analysis confirms the robustness of these rankings. The integrated MOST–AHP–TOPSIS model proves effective in aligning organizational missions with quantitative decision-making, resulting in more objective and evidence-based strategy formulation. This framework provides a practical tool for industrial managers to enhance competitiveness, operational efficiency, and strategic adaptability within the steel pipe sector.
