基于批次管理的铁路施工水泥库存控制研究
Research on batch management-based inventory control of cement in railway construction
摘要
Abstract
Effective inventory control of cement silos at concrete mixing stations in railway construction projects is crucial.Considering the unique chemical properties of cement,it is necessary to establish inventory control models with batch management and numerical discretization.Based on the equal-bin method,we constructed 2-equal-bin models and multi-equal-bin models.We optimized these models considering their fixed order bin numbers and developed a variable order bin model.Discussions were conducted on both continuous review and periodic review scenarios.By considering the integer relationship between cement silo capacity and cement transport tanker capacity,we tailored cement silo capacities to reduce operational costs in railway construction projects.Simulation analysis was used to determine the optimal reserve levels,fulfillment rates,and utilization rates of cement silos.The research results indicate that the multi-equal-bin inventory optimization model is suitable for cement inventory control.The introduction of a multiplier coefficient for cement tanker capacities results in unconventional variations in inventory costs.Continuous review strategy is more applicable when cement transport tanker capacities are larger.The multi-equal-bin optimization model prevents excessive capital tied up due to additional cement silo reserves and improves the utilization rates of cement silos.When designing concrete mixing stations,it is advisable to plan cement silo capacities appropriately,preferring smaller but more silos to enhance utilization rates and reduce inventory costs.The equal-bin system inventory control strategies studied in this paper can provide recommendations for storing other materials in tank bodies during railway construction.关键词
