Modelo matemático para optimizar el costo del transporte pesado de carga agrícola, utilizando programación lineal, para la compañía de transporte pesado interprovincial Jaime Roldós Aguilera Sociedad Anónima.

Abstract

The objective was to design a mathematical model to optimize the cost of transporting heavy truckloads of agricultural products, utilizing linear programming, for the interprovincial transportation company “Jaime Roldós Aguilera Anonymous Society.” The model was based on the study of fixed costs and variables by which we analyzed the distance, cargo volume, arrival and departure time, fuel and lubricants, and other variables that intervene in the fixation of the cost of transportation. The investigative work had a quantitative and descriptive focus and its non-experimental character design with transverse shortcuts; inductive, deductive, and systemic methods were employed. To collect information, surveys and questionnaires were used as a technique as well as an instrument to provide valid and trustworthy data. With a population of 80 associates from the company and a sample of 66, it was evidenced that 65% of those surveyed were ignorant about the true calculated cost of transportation, and 76% considered that the mathematical model for defining the calculated cost in this economic area was necessary, given that the typical form of calculating it was by simply comparing it with the competition, as indicated by 30% of those who transport these goods. In conclusion: a major change in expenses is reached with the methods of Vogel and Russel which is validated by the system WINQSB, Herramienta Network Modeling.
