The growth of sanitary products shipped through cold logistics, in recent years, has been sustainable and significant. This increase brings with it challenges aimed at maintaining the products in the established temperature ranges which can assure and keep their temperature in optimal levels so that quality can be kept as this might affect the health of customers. The mismanagement deficiencies of the cold chain affect the profitability of the companies in the chemicalpharmaceutical sector, due to the returns caused by the delivery of low-quality products. In this context, this research proposes a solution that includes the application of three tools: Jidoka, the MRP II planning system, and the Standardization of Work to reduce the level of returns. The proposal is based on the improvement of the packaging process, by applying new inventory policies, optimal mechanisms for the management...

Tropical high-mountain permafrost has a unique thermal regime due to its exposure to strong solar radiation and to rough surface snow morphology, which reduce ground heat transfer from the surface. Latent heat transfer and higher albedo that occur during the snow-covered season contribute to positive feedback that supports the presence of permafrost. This preliminary study reports on the thermal state characteristics of tropical mountain permafrost in Peru. This work also evaluates the potential combined impact of the El Niño–Southern Oscillation (ENSO) in the mountain permafrost of the Coropuna and Chachani volcanic complexes, both located at the western edge of the southern Peruvian Altiplano. Temperature monitoring boreholes were established at 5,217 m at Coropuna and 5,331 m at Chachani, and electrical resistivity was surveyed in both sites. This 7-year discontinuous record of per...
