Development of the planning model of the production and cutting of the paper web ensuring the quality of the finished products

Abstract

Abstract The problem of the planning of pulp and paper production has been investigated, a complex of model and algorithmic programs as well as a software of an automated system of planning and calculating of the cutting methods on a longitudinal slitting machine (LSM) is expected to be a result of this planning. An integrated model for planning paper production and multi-stage cutting of rolled and sheet products has been proposed based on methods, models and algorithms of optimal cutting from the condition of the ensuring the products orders fulfillment with minimal losses. A scientifically based method and algorithm of generating a set of acceptable ways of rolls cutting, criteria of generating a set of acceptable ways of rolls cutting as well as an integer algorithm of the result of the problem solving have been considered. All real restrictions encountered in the manufacturing sector have been taken into account. The results of the planning models usage for real production process have been presented.
