    Six sigma en empresas de infraestructura vial
    (Universidad EIA, 2009) Escobar Garcés, Tatiana; Pérez Ramírez, Lucas; Sierra, Jorge Enrique
    ABSTRACT: The Project that has been developed is SIX SIGMA in road infrastructure companies. It is a methodology based on statistic processes control generating a culture of: improving constantly, focus on the customer. Eliminate re – processes and restructure them, have a statistic control of the processes and pick up profits. The authorization of LATINCO S.A (road infrastructure company) was very important to develop a pilot prove in any of their processes. The pilot prove was developed in the crushing machine process because the importance of the final product in the asphalt mix production. It means, the final product is vital to the construction of a road. To start the pilot prove, the construction site were visited many times where the crushing machine was and the process could be appreciated and besides, listening the worries from the people that work with the process. The opportunity to listen the people who built the machines was useful to understand the operative and technical fundamentals of the plants. From these meetings were born doubts and necessities that had to be fixed: lack of knowledge of the material to be processed, lack of preventive maintenance, bad stock of provisions and deficiency on the historic record of the bad performance of the plant. The SIX SIGMA had to be started to improve the production and fulfill the necessities told for the experts. For the lack of knowledge in the material to be processed petrography essays were done that gave chemical and physical conditions of the material, for the lack of preventive maintenance, the machines’ catalogs were studied (cone y crushing machine) and daily control and horary formats were developed, for the bad stock of provisions, the plant engineer said what kind of provisions were needed and for the bad historic record a statistic analysis were done in the months of July and August creating and starting the data base for the company. When all the implementations were realized, a meeting with the engineer in charge of the plant showed his satisfaction for the results that were obtained and the notable improves: increase of the production, historic records formats, preventive maintenance formats for the care of the machine and generate the culture of the importance to know what kind of material it’s going to be processed helping futures acquisitions.
