Linear programming; Papermaking machinery


The purpose of this study was to determine if it is feasible to use linear programming as an aid in the designing of a paper mill. The study was confined to three areas (1) the pulp preparation area, (2) the fiber preparation area, and (3) the electrical power distribution system. This study disclosed that linear programming was helpful in the pulp preparation area in selecting the most economically sized chipper for a given production requirement. It was, however, not practical to use linear programming for the other two phases of the study. The reason for this was due to the fact that the latter two operations could not be set up in terms of linear equations. The conclusion was that where a piece of equipment, such as the disc refiners in the fiber preparation area, had to be in continuous operation throughout the 24 hours of the day and it did not require an attendant it was not possible to set up linear equations. The same was true for the power distribution system. The chipper application, which was studied in the pulp preparation area, differed from the refiner and the power system study on two major points (1) a portion of its output is stored; therefore, it is not necessary for it to be in operation 24 hours a day and (2) it requires an attendant to feed the logs into it. These two factors make it possible to set up a linear equation for each size of chipper. From these equations it is feasible to solve for the most economical unit either graphically or algebraically. The graphical method was by far the simpler of the two for this particular study.
