The dynamics of aggregate planning

J. Dejonckheere, S. M. Disney, M. Lambrecht, D. R. Towill
2003 Production planning & control (Print)  
Filter theory allows us to relate these dynamics directly to present day production planning strategy as observed in much industrial practice.  ...  These strategies range from "level scheduling" (i.e. lean production) right through to "pure chase" (i.e. agile manufacture) with appropriate simple algorithmic control support via APIOBPCS software.  ...  a dynamic performance comparison (as distinct from the costs comparison of Table 2 ) we need to examine how the paint factory might have responded to the "level scheduling" and to the "chase" strategies  ...

Optimal Factory Scheduling using Stochastic Dominance A* [article]

Peter R. Wurman, Michael P. Wellman
2013 arXiv   pre-print
We examine a standard factory scheduling problem with stochastic processing and setup times, minimizing the expectation of the weighted number of tardy jobs.  ...  Because the costs of operators in the schedule are stochastic and sequence dependent, standard dynamic programming algorithms such as A* may fail to find the optimal schedule.  ...  Acknowledgements We are gratefu l to the anonymous reviewers and stu dents in the U-M Decision Machines Group for sug gestions about the presentation of this work.  ...
