Avaliação e monitoramento da eficiência nas áreas de apoio dos sistemas produtivos

Abstract

The indicators for measuring productivity and efficiency of production areas are wellknown in the academic and business worlds. In contrast, the supporting branches of the production systems where the inputs and outputs are unclear, it is imperative to make research advancements. The general objective of this study is to propose methods to analyze and monitoring, longitudinally, the efficiency of the support area of the production system from a multinational company in the metal-mechanic segment. A case-based modeling was performed using DEA DDF through the internal benchmarking procedure. For this reason, a pilot application was developed in the Material Control and Production Planning sector of the company under study. The main results take into account the proposal of a conceptual model for identifying system variables, which can be replicated for other support areas. Furthermore, a dashboard for monitoring monthly the sector's efficiency is presented, with relevant information for the area managers. The contributions of the work can be divided into theoretical and practical. Among the theoretical contributions, the generic conceptual model for evaluating efficiency, the validation, and applicability of the DEA DDF as a recurring indicator for monitoring efficiency and the empirical discussion on the effect of adding new DMUs in relation to the displacement of the efficient frontier stand out. Finally, in the business context, the study contributes by providing a dashboard for monitoring the results achieved by the support area, in addition to introducing an indicator for measuring the efficiency of support areas with high replicability, which is different from the widely used indicators that measure effectiveness.
