Dynamic environments are usually characterized by high uncertainty with respect to future production needs. In traditional layout evaluation, emphasis is placed on factors such as proximity and adjacency since they increase material handling efficiency reducing operational costs. It is usually recommended to consider additional factors in the analysis, such as robustness, flexibility, sufficiency, and use of space. These factors reinforce the idea that layout flexibility is in part related to other types of manufacturing flexibility. In this article, a method to evaluate and improve layout flexibility in dynamic environments is proposed. More explicitly, it is proposed the measurement of the enablers of a layout that is capable of reacting to external and internal uncertainties that arise due to changes in the production needs. The proposed method is implemented in nine stages using matrices to measure the impact of proximity between departments, using production space and an association with other types of manufacturing flexibility for layout flexibility evaluation. The present study also presents a proposition in which the traditional Quality Function Deployment (QFD) analysis is performed in reverse. The method is illustrated in a case study carried out in a company in the metal component processing industry.
