Predicción de tiempos estándar en líneas de ensamble usando mínimos cuadrados en modelos lineales multivariables

Abstract

Currently, the high competitive environment of the assembly industries has been an engine for them to seek differentiating factors for improving their efficiency. One of these factors is the study of methods (referred to the analysis and critical and systematic examination of how a task is carried out at present, facilitating to find more effective methods) and times, which allows alleviating internal and external aspects that affect productivity, since it provides the basis for management decision making. The present work has two basic objectives; firstly, the calculation of standard times within the enterprise operative area and, additionally, the development of a mathematical model for time prediction. For the fulfillment of these purposes, a referential conceptual framework was established about the study of time and multiple linear regression model, to then elaborate the procedure to follow for the development of the mathematical model of prediction, together with its validation. The study concludes with a discussion on the importance of having models to estimate standard times in business decision making, and the establishment of relevant conclusions.
