1. A method of balancing workload across multiple cells in a cellular manufacturing environment, the method comprising: compiling a listing of a plurality of jobs and cells using a computer operable processor, wherein the plurality of jobs are to be produced by at least some of the plurality of cells, and each of the cells include at least one production device; and auto-splitting the jobs into smaller sized lots using a split-then-merge operation to adapt the lots to cell workloads while returning lot sizes that are no more fine grained than necessary.
