Increasing Production and Transportation Efficiency for Ready-Mixed Concrete–A Multiple Plants Type
Keywords:
Multiple plants, Allocation, Integer linear programmingAbstract
Solving scheduling problems associated with the transportation of ready mixed concrete is regarded as extremely complicated, particularly those involving multi-plant transportation due to many relevant factors under hasty decision-making circumstances. In this study, problems were analyzed into 2 main parts: 1) allocation of production orders to each branch of ready-mixed concrete production plants in proper ways and 2) production and transportation scheduling. In this model, Integer Linear Programming was applied to increase efficiency in proper allocation of production orders to each plant to be applied in production planning. The outcomes obtained result in reduction of waiting time and labor costs, which is able to create satisfaction to construction units based on the criterion of the minimum total travel time spent at a time as an objective.
