The use of the Operational Research as fundamental instrument for maximization of the financial income in the company of materials of building site – Malanje

Abstract

The main objective of this article is to present a proposal for the application of Operational Research using linear programming to maximize the financial income of the civil construction material company in Malanje. The study was conducted based on the use of the quantitative method. Meantime, after the problem was formulated the decision variables were defined, the formation of the restrictions and later the objective function was identified according to the estimated profits in each product of the company, which allowed to formulate a mathematical problem with probabilistic modeling, of which six iterations were carried out to find the best optimal solution that would maximize the company's financial income. Through the study carried out, it was concluded that the optimal solution of a linear programming problem to maximize the company's income is the optimal solution or feasible point that presents the highest value for the objective function. From this research, it is possible to understand companies that tend to remain competitive in the market must make a set of efforts to satisfy customer demand.
