Simulation-Based Approach for Optimizing Chicken Consumption Forecasting, Restocking, and Decision-Making in Pinoy Frito

This study focuses on developing a simulation-based framework for optimizing chicken consumption forecasting, restocking, and decision-making in Pinoy Frito, a Filipino fried chicken business. The research integrates Holt-Winters exponential smoothing forecasting and Monte Carlo simulation to capture demand variability and test restocking strategies. Historical sales data, lead times, and operational costs were analyzed to simulate realistic inventory behavior. The main goal is to minimize inventory cost while maintaining target service levels. Results from simulation experiments comparing restocking policies—continuous review (Q,R), periodic review (s,S), and safety stock strategies—show that the proposed system enhances cost efficiency and reduces waste by approximately 10–15%. The findings contribute to data-driven decision-making for small and medium food enterprises and align with the national goals of food security, competitiveness, and sustainability. Chapter 1: Introduction In the food industry, accurate demand forecasting and efficient inventory management are vital for balancing customer needs while minimizing waste and cost. Pinoy Frito, a local fried chicken business, often experiences demand fluctuations caused by factors such as paydays, holidays, and seasonal events. These fluctuations make it difficult to maintain the right level of chicken supply, often resulting in either stockouts that limit sales or overstocking that leads to spoilage. Such inefficiencies directly affect profitability and customer satisfaction, underscoring the need for a more data-driven and adaptive approach to inventory planning. This study focuses on developing a simulation-based framework that integrates forecasting and restocking strategies to enhance decision-making for Pinoy Frito. Using the Holt-Winters exponential smoothing model for demand forecasting and Monte Carlo simulation for evaluating restocking policies, the research aims to provide a systematic approach to managing uncertainty in food inventory. The goal is to determine the most cost-effective restocking strategy that balances holding costs, service levels, and demand variability. Ultimately, this research contributes to the broader goal of improving operational efficiency in small and medium-sized food enterprises. By leveraging simulation-based forecasting and optimization techniques, Pinoy Frito can reduce food waste, ensure consistent product availability, and make informed business decisions. This approach aligns with national initiatives promoting sustainability, competitiveness, and food security through technology-driven innovation. 1 Posted on 17 Nov 2025 — CC0 1.0 — https://doi.org/10.22541/au.176341096.66462683/v1 — This is a preprint and has not been peer-reviewed.

Journal of Industrial and Systems Engineering, 19(2), 130–145.* The simulation shown above used a Holt-Winters method and Monte Carlo simulation; the simulation shows a probability and a trend based forecast. The Holt-Winter model captures the trend patterns shown in the historical sales data while the Monte Carlo simulation adds random fluctuations to forecast different types of outcomes. In this figure, the simulation for Calasgasan shows an average of 0 chickens/day, suggesting that it is either a minimal sales or insufficient data for a reliable forecast. Despite this, the simulation successfully shows the unpredictability and the trend behaviour, allowing a better explanation of sales fluctuation and future demand expectations. Overall, the use of these simulations provides a data-based perspective for understanding the consumption behaviour and organizing a future production and distributions. Chapter 5: Summary and Conclusion This study described the use of predictive analytics and simulation techniques in improving sales forecasting, inventory management, and stock control for Pinoy Frito branches located at Daet, Camarines Norte. Its associated simulation model was designed to analyze sales trends, estimate the demand for each product, and predict inventory needs, thus enabling each branch to make more valuable and effective decisions. By integrating predictive analysis into the business process, this study demonstrated how technology and data modeling can play an important role in operational efficiency and reduction of resource wastage. The simulation results indicate that the capability to forecast future demands will provide the branch man- agers with more reliable planning of restocking activities while avoiding overstocking or understocking situa- tions. Furthermore, the predictive model will provide insight into consumption behavior and market trends, which may also serve as a basis for strategic decisions in future operations. The findings of this paper reveal that predictive analytics can play a relevant role in the modern management of business entities, and especially small and medium enterprises like Pinoy Frito. Simulation-based forecast- ing will enhance sales predictions, allowing each branch to optimize resource utilization, reduce operational 5 Posted on 17 Nov 2025 — CC0 1.0 — https://doi.org/10.22541/au.176341096.66462683/v1 — This is a preprint and has not been peer-reviewed.
