Abstract
A new approach for dealing with a huge number of cutting pattern combinations encountered in two-dimensional Cutting Stock Problem (CSP) is described. Firstly, cutting patterns are produced according to a novel cutting method LF(Lease Fit) algorithm which can effectively cuts a sequence of small rectangular pieces from a big stock, heuristically maximizing the stock’s utilization ratio. Then Genetic Algorithm (GA) is applied to search for a near optimal solution which consists of many patterns namely a pattern combination. To evaluate the combination’s fitness, LP (Linear Programming) algorithm is used in polynomial time without bringing about much error. The performance and efficiency are justified by numerical experiments.
