Propuesta de un Modelo Econométrico para el Costo de la Materia Prima en la Producción de Cemento Portland en la Empresa Cemento Chimborazo

Abstract

"An econometric model was developed for the cost calculus of raw material in the Portland cement production of the Chimborazo Cement Enterprise located insane Juan Chico, Chimborazo Province, with a base consisting of 720 from the 2004 — 2007 accounting period as the manipulated data will be more reliable and rapid providing simpliñed information with explicative purposes. The applied techniques were Correlation and Multiple Regression, elected according the adjusted-R resulting near to 1, which foresees that this model will be good. The used software was Excel and Minitab.

The model consists of determining the most relevant monthly cost and economic factor essential as raw material shown in the equation:

Total cost = 3.10*direct labour + 2.46""acquired sandstone + 1.84""energy and fuel + 2.13'salaries and occasional benefits + 0.57*consumption items.

Simulating this model and applying descriptive statistics the variable behavior is observed for a total cost, the sandstone being the raw material contributing with 39% ¡.e. 17564.6 USD and consumption costs with an optimum contribution of 24687 USD representing 12% in the product elaboration.

This econometric model is recommended for a better financing control because

ofthe opportune information for the decision-making."
