Abstract

This study aims to systematically review the application of sensitivity analysis in operational decision-making based on linear programming. The research method used is a Systematic Literature Review (SLR), analyzing scientific articles published between 2018 and 2024 from databases such as Scopus, ScienceDirect, SpringerLink, and Google Scholar. The review focuses on how sensitivity analysis is employed to evaluate the stability of linear programming solutions in the face of parameter changes, such as objective function coefficients, constraint bounds, and resource availability. The results indicate that local sensitivity analysis approaches are the most commonly used due to their simplicity and ease of interpretation. However, they fall short in capturing parameter interactions and complex uncertainty. Therefore, recent studies have started to explore global sensitivity methods, such as Morris and Sobol techniques, as well as geometric visualization approaches to provide a more holistic understanding. This study recommends integrating both local and global approaches and utilizing computational tools to enhance the robustness of operational decisions. The findings are expected to serve as a reference for more adaptive, efficient, and resilient decision-making under uncertainty.

Abstract

This study is a mini literature review aimed at exploring the use of the Math Master software in enhancing students’ computational thinking skills. Computational thinking is a crucial 21st-century skill, particularly in technology-based mathematics learning. This article reviews several relevant studies that discuss the use of educational software, specifically Math Master, in helping students solve mathematical problems systematically, logically, and efficiently. The review findings indicate that Math Master can serve as an interactive tool that supports conceptual understanding and encourages algorithmic thinking among students.

Abstract

Penelitian ini membahas pengambilan keputusan ekonomi dalam konteks persaingan, promosi, dan kolaborasi bisnis dengan menggunakan pendekatan teori permainan. Metode yang digunakan adalah Systematic Literature Review (SLR) terhadap 10 artikel ilmiah yang terbit pada periode 2020–2025, terdiri atas jurnal nasional dan internasional. Analisis difokuskan pada tiga model teori permainan, yaitu Nash Equilibrium, Prisoner’s Dilemma, dan Mixed Strategy. Hasil kajian menunjukkan bahwa Nash Equilibrium berperan dalam menjaga kestabilan strategi harga dan promosi pada pasar yang kompetitif. Model Prisoner’s Dilemma mengungkapkan bahwa persaingan berlebihan dapat menimbulkan kerugian bersama, sehingga kolaborasi bisnis mampu menghasilkan nilai ekonomi yang lebih optimal. Sementara itu, Mixed Strategy relevan dalam ekonomi digital karena membantu pelaku usaha menghadapi ketidakpastian pasar. Penelitian ini menegaskan bahwa teori permainan berfungsi sebagai kerangka strategis dalam pengambilan keputusan ekonomi modern serta memiliki implikasi bagi pengembangan kebijakan dan strategi bisnis berbasis kolaborasi. ABSTRACT This study discusses economic decision-making in the context of competition, promotion, and business collaboration using a game theory approach. The method used is a Systematic Literature Review (SLR) of 10 scientific articles published between 2020 and 2025, consisting of national and international journals. The analysis focused on three game theory models, namely Nash Equilibrium, Prisoner's Dilemma, and Mixed Strategy. The results of the study show that Nash Equilibrium plays a role in maintaining the stability of pricing and promotion strategies in competitive markets. The Prisoner's Dilemma model reveals that excessive competition can cause mutual losses, so that business collaboration can produce more optimal economic value. Meanwhile, Mixed Strategy is relevant in the digital economy because it helps businesses deal with market uncertainty. This study confirms that game theory serves as a strategic framework in modern economic decision-making and has implications for the development of collaboration-based business policies and strategies.
