  • Application of Lean Techniques to Reduce Preparation Times: Case Study of a Peruvian Plastic Company

    Silva Reyes, Alfredo Jeampiere; Salas Castro, Rosa Fernanda (Research India Publications, 2017-11)
    This article examines the problem of an increase in product returns for a company that produces plastic films for flexible packaging. Among the factors that have resulted in the increase of returned products are defects in the films caused by the poor manipulation of materials and, above all, the hard point in the coils caused by excessive extruder preparation time, causing the extrusion head to overheat as well as uneven extrusion. Extrusion is a key process in the production of plastic materials as it transforms polypropylene and additives into plastic sheets. The delay in the preparation time caused by machine operators leads to the overheating of the extrusion head and, therefore, defective products that are ultimately returned to the company by customers. In order to confront this problem, a proposal was developed using the SMED tool of Lean Manufacturing in order to reduce the preparation time of the extruder and to increase the productivity of the company. For the validation of the proposal, we simulated the system to determine the resulting reduction in extruder preparation time.

    Ramos Palomino, Edgar David; Hilario Meza, Slee; Robles Montes, Diego; Sotelo Raffo, Fernando; Wei Shuo, Lo (International Journal of Innovation, Management and Technology, 2017-02)
    The paper is to explore a model of supply chain management organic coffee in San Martin Region, which was by a long-term research project for organic coffee supply chain management in Peru. The investigation was consolidated with items of researchers who have experiences in the evaluation and analysis of the supply chain of agricultural products worldwide; on the other hand, it is also taken into account the risks affecting the development and fluency through whole supply chain. The contributions here is proposed model of supply chain management organic coffee is suitable for exploring external and internal problems encountered decrease the efficiency of the supply chain. The model is important to analyze and require observations of specialists to collaborate to perform basic modeling that can help solve the problems that improving processes and organizations in the coffee farmers’ cooperatives in the domestic and foreign market, and achieve recognition for their quality and sustainability in Peru.
