Abstract

This study aims to analyze the performance of a queueing system in a small-scale coffee shop operation using the Monte Carlo simulation method based on historical data from 2022–2026. Coffee shop operations exhibit stochastic characteristics influenced by fluctuations in customer arrivals and service time variability. Data on daily visitors, revenue, cost, and profit were processed using Microsoft Excel to construct empirical probability distributions. The simulation was executed through thousands of iterations to ensure statistical stability. The results indicate that the model effectively captures operational uncertainty, with convergent average daily profit and measurable downside risk assessed through percentile analysis and Value at Risk (VaR). The findings provide an analytical foundation for managerial decision-making regarding service capacity and cost control strategies. Monte Carlo simulation proves to be an effective tool for performance evaluation and risk management in small-scale service businesses.

Abstract

The growing global demand for energy and the depletion of fossil fuel resources have accelerated the transition toward sustainable energy systems. Biomass has emerged as an important renewable energy source due to its abundance, carbon-neutral characteristics, and relatively stable energy supply. However, biomass has complex chemical compositions such as cellulose, hemicellulose, lignin, moisture, and ash, which significantly affect combustion characteristics and energy performance. This study analyzes the relationship between biomass composition, combustion characteristics, and energy stability using a bibliometric approach. A dataset of 3,521 scientific publications from the Scopus database (2021–2026) was analyzed using VOSviewer and Bibliometrix. The results show increasing research trends in biomass combustion and thermochemical processes. However, the integration between biomass composition and energy stability remains limited, indicating important opportunities for future interdisciplinary research in biomass-based energy systems.
