論文摘要：
This case study delves into the operational challenges confronted by a company specializing in polyurethane products, particularly elastomers, and those demanding abrasion resistance. Persistent delays in product deliveries, stemming from inadequate production planning and insufficient capacity, underscore the need for a strategic solution. We advocate for the implementation of mixed-integer programming as a production planning tool, aiming to optimize resources and maximize revenue. The proposed mathematical model incorporates constraints related to machine utilization, time allocation, and demand fulfillment. An analysis of production data pinpoints May 2022 as a period of suboptimal efficiency. Following the three-month post-implementation period, the company witnessed a notable 5.85% increase in revenue and a 4.90% improvement in product delivery. Looking ahead, sustained improvement can be achieved by enhancing production capacity through measures such as increased shifts or optimized working.
