Nowadays, ineffective logistics for the distribution of medicines causes inefficiency in the immediate delivery of these drugs to the population, producing a public health problem. In this sense, the present study, developed in the department of Puno, has the purpose of improving the distribution of medicines and supplies by applying the lean methodology, because Puno has the most deficient installed capacity in Perú.

In this work, the lean methodology has been applied in order to improve the distribution logistics management process. Puno has been selected as the study population, and as samples, the health establishments in the districts of Puno, Melgar and Carabaya have been considered.

To apply the improvement plan and carry out proper monitoring, the Lean engineering tools of VSM were used to represent the process, as well as the Just In Time system was used to apply the improvement plan and the KIPs were used to control the process.

For the distribution in Puno, a new structure of the process was proposed applying a Lean operation tool. The result evidences a reduction of 11.88 hours in the process. In addition, waiting times related to the shipment of medicines were reduced, generating a time saving of 2,5 hours.
