Construction work consumes a large amount of
construction reinforcement steel and it demands this steel in
various particular sizes according to structural designs. The
steel have to be cut to the right sizes before uses. The cutting
process creates a lot of trim loss and costly wastes. This
research develops a new procedure for arranging cutting
plans with minimum trim loss. The procedure is based on
the optimization of one dimensional cutting stock problem.
A set of efficient cutting patterns is generated first and then
the cutting replications are determined from the
optimization. The problem model has oversupply
constraints which do not allow cutting any item more than
the demanded pieces. Few remaining under supplied items
are lastly cut using the best fit decreasing algorithm.
Therefore, the cutting plans created from this procedure
will not make any oversupply which becomes waste and they
will cut all pieces exactly as demanded. Test results
indicated that this developed procedure could produce low
trim-loss cutting plans. Also, the suitable number of efficient
cutting patterns and the suitable allowable trim loss of the
patterns could help result good cutting plans.
