One of the critical challenges in decision-making is avoiding decisions becoming too subjective or too objective. To address this issue, the chapter focuses on discussion of integrating subjective and objective weighting methods, which provides a balanced approach to improve decision accuracy and reliability. This chapter explores the comprehensive weighting method, emphasizing its importance and outlining the different types available. It highlights the distinctions between comprehensive weighting and traditional subjective or objective approaches, examines the influence of proportion coefficients on weight assignment, and evaluates the effectiveness of various integrated methods. Additionally, the chapter covers the practical implementation of these methods using MATLAB and concludes with a summary of key insights.
