Time-Based Manufacturing System Design for Softwood Lumber Production
… involved a case study of a southern yellow pine lumber manufacturer. Value stream mapping was used to evaluate the current lead time for the lumber manufacturer as well as design future state systems. Current state evaluation discovered an average lead time of 35.3 days according to six months of …
