Scheduling (production processes) - Wikipedia

Mathematical programming methods involve formulating the scheduling problem as an optimization problem where some objective, e.g. total duration, must be minimized (or maximized) subject to a series of constraints which are generally stated as a set of inequalities and equalities. The objective and constraints may involve zero-or-one (integer ...

AN OPTIMIZATION-BASED ALGORITHM FOR JOB SHOP

scheduling of batch machines with setup requirements was addressed in Luh et al. (1997b). A “forward” dynamic programming(FDP) algorithm was embedded within the LR framework for job shop scheduling in Chen et al. (1995). In the method, only machine capacity constraints are relaxed, and part level subproblems are formed and solved byusingtheFDP.
