Abstract

In this study, the authors develop a systematic network flow model designed to help RMC carriers effectively adjust schedules following ready mixed concrete (RMC) mixer breakdowns. A time-space network technique is employed to formulate the production of the RMC and truck fleet flows in the dimensions of time and space. The model is formulated as a mixed integer network flow problem with side constraints. A solution algorithm, incorporating a problem decomposition technique and the use of a mathematical programming solver, is developed to efficiently solve the problem. Finally, the model and solution method are evaluated by performing a case study. The test results show that the model and the solution algorithm could be useful for actual operations.
