This study aims to develop a decision-support system using Integer Linear Programming (ILP) to optimize workforce allocation in the sewing department of Jacksonville Creative Concept Mfg. Inc., located in Alaminos. The company currently faces recurring issues of overstaffing and understaffing due to the absence of a structured manpower planning system and the unpredictability of employee attendance, which is heavily influenced by the piece-rate compensation structure. A mixed-methods approach was employed, combining quantitative data from company records and surveys with qualitative insights from interviews and observations. A total of 43 piece-rate sewers participated in the study. Survey results also indicated that employees were open to the use of computerized scheduling tools. The study concludes that the proposed LP-based system can significantly improve operational efficiency and fairness in manpower distribution. Recommendations for future adoption include system training, real-time data integration, and expansion to other departments.
