Rough mill simulator version 3.0: an analysis tool for refining rough mill operations.

摘要

ROMI-3 is a rough mill computer simulation package designed to be used by both rip-first and chop-first rough mill operators and researchers. ROMI-3 allows users to model and examine the complex relationships among cutting bill, lumber grade mix, processing options, and their impact on rough mill yield and efficiency. Integrated into the ROMI-3 software is a new least-cost grade mix solver that determines the most inexpensive grade mix to process with regard to both purchase and processing costs. In addition, ROMI-3 now has a new gang-ripsaw optimizer that determines the optimal fixed-blade saw spacing sequence based on the user's lumber width distribution, cutting bill, and processing configuration. For each simulation, ROMI-3 reports the amount of lumber and number of cutting operations required to complete processing of a cutting bill, as well as part tallies by lumber grade and overall..
