Inside of the EP the tools are many that assist in the good execution of a production, are innumerable the existing tools today, knowing some of them it is known of the existence of MRP (Material Requirementes Planning, or calculation of the necessities of materials) and MRP II (Manufacturing Resources Planning, or planning of the manufacture resources), these in turn function established in the logic of the calculation of necessities, its objectives, its advantages and disadvantages, Corra and Gianesi (1993). Also cited for them Corra & Gianesi (1993, p.122) the functioning of the same ones that? if it bases in a basic register that represent the position and the plans with respect the production and stockage of each item, either it a raw material item, semifinished or finished, throughout the time? . making one it analyzes and knowing geometry the relationship between both can be seen, therefore in the study of Geometry it has the linear system, where if colheta given (determined values) and to the sum in matrix form having the exactness of asked for results, in this way the MRP and the MRPII has much similarity with the system, therefore as in the linear system also it can be collected definitive data as of the stockage and thus transforming them into matrix and later it calculates them in the way that can be supplied the results. In accordance with Robles Jr (2003, p.73): However, the accompaniment of the attendance to the requirements of the Quality requires the creation of appreciable amount of Pointers of Quality. These pointers are sumarizados tables and for the spreading to the different operational and managemental levels. One knows that a production to be good has that to result in quality, and this quality it has some forms of being measured as already it was cited previously, and to be able to apply these measures as table creation is necessary a space knowledge, and also to know to collect these data thus to be able pociona them in the table and to obtain to make a good work, and is assists with it of the geometry that can be carried through the same, when becomes the deepened study of matrices.
