A production scheduling method of MTO-MTS hybrid prefabricated building components

Abstract The invention discloses a production scheduling method of MTO-MTS hybrid prefabricated building components, which comprises the following steps: building a total time calculation model. According to the total time calculation model and whale optimization algorithm, the best schedule of MTO is obtained. Go to the next step when the MTO components are not postponed and the existing inventory quantity is less than the maximum inventory capacity, otherwise, take the MTO optimal schedule as the final production schedule and go to the last step. According to the total time calculation model and heuristic algorithm, MTS components are inserted into MTO optimal scheduling to obtain mixed production scheduling. If the total time of mixed production scheduling is less than or equal to the total time of MTO optimal scheduling, take the mixed production scheduling as the final production scheduling, otherwise take MTO optimal scheduling as the final production scheduling, and then proceed to the next step. Transmitting the final production schedule to the prefabricated assembly line module to execute the production order, and updating the planned completion time of MTO assembly order and the existing inventory quantity of MTS assembly. Acquiring the order information of MTO components to be produced in the order management module and the existing inventory quantity of MTS components in Si the standard component inventory monitoring module The total time calculation model based on delay, inventory and mutual S2 conversion between two modes in MTO-MTS mixed mode is constructed According to the total time calculation model and whale optimization S3 alg orith m, the sched uIi ng o f allI MTO co m p one nts co rresp ondi ng to allI order information is optimized to obtain the best MTO schedu le Take MTO Judging whether MTO components have no delay and lOne whether the existing inventory quantity is less than the Trnmiteinlrdutosceulttepeariae as7 final Is maximnum ni nve nto ry capacity production noo schedule IAll are ves Acco rd ing to the total ti me calcu lati on m odelI and he uristle c algorithm, at least one MTS component is inserted into the MTO optimal schedule to obtain the mixed production schedule Take MVTOV optimal J udg ing whether the total ti me o f mixed p rod ucti on 8 schedule as Noscheduling is less than or equal to the total time of MTO Mial I Ioptimal schedLAlng production scheduleYe Take the mixed production schedule as the final production
