Model for optimization of phase processes by the linear programming method

Abstract

The problem of optimization of a multiphase production process by the linear programming method is very frequent in manufacturing practice. Instead of a classical solution to the problem, i.e. creation of constraint equations per production phase, the paper proposes the methodology of forming of a unique (summary) table which can be used for creation of a complex mathematical model of the problem in a matrix form. The method is illustrated on the example of an optimization process of manufacturing and mounting of a hydraulic valve for regulation of pressure and flow, which is foreseen for installation on hydraulic bar feeders for CNC machines.
