Analysis and Proposal for Improvement of the Preventive Maintenance Service Process Using Lean Tools: Case Study

EasyChair Preprint no. 5873

Abstract

This article aims to improve preventive maintenance processes in analytical instrumentation equipment for after-sales service. The evaluation of the problem was carried out by mapping the current value, classifying the types of activities that generate value to be optimized with the use of tools based on lean service, allowing to eliminate waste that affects customer satisfaction. Preventive maintenance was chosen as the activity that generates the greatest value for after-sales services. The use of the following tools is proposed: inventory control ABC, Heijunka, 5s and Kanban. Additionally, the stages of the planning, programming and CRA (consumable, spare and accessory) process were restructured. Regarding the research methodology, it is applicative - experimental level. Achieving as estimated results in the proposal to improve the after-sales service process; lead time decreased by 50.8% and the process cycle time decreased by 18.98%. The case study concludes with the improvement of service quality, customer satisfaction and increased productivity.

Keyphrases: 5 S, Heijunca, Kanban, Mapeo de valor, Servicio Esbelto
