A Lean-DEA approach for continuous improvement in Brazilian public hospitals.

Purpose: Propose an integrated approach of Lean Healthcare (LH) with Data Envelopment Analysis (DEA), establishing best practices for waste reduction and process improvement along with hospital efficiency.

Design/methodology/approach: The study proposes a two-stage approach integrating LH and DEA to enhance hospital efficiency. The first stage identifies efficient hospitals post-LH implementation and projects efficiency for inefficient ones using ideal projections.

A proposed multistage evaluation approach for Higher Education Institutions based on network Data envelopment analysis: A Brazilian experience.

The evaluation of Higher Education Institutions (HEIs) is a challenging task, due to the complexity inherent in the context in which they are inserted, the different institutional profiles, the variety of resources used and the results offered in the performance of their mission. In this way, the present study proposes an evaluative approach that aims to measure efficiency taking into account the diverse activities characteristic of university institutions. To this end, a data envelopment analysis (DEA) approach, known as Network DEA, is used, which encompasses the different processes and subprocesses that take place within these institutions.

The joint use of life cycle assessment and data envelopment analysis methodologies for eco-efficiency assessment: A critical review, taxonomy and future research.

Eco-efficiency has become a cornerstone for any company that seeks to improve their environmental and economic aspects. In this context, the joint use of Life Cycle Assessment and Data Envelopment Analysis, known as LCA + DEA methodology, is an emerging and growing line of research. LCA estimates the environmental impacts of the products or services, while DEA evaluates their efficiency, providing targets and benchmarks for the inefficient ones.

Comparing two CF+DEA methods for assessing eco-efficiency from theoretical and practical points of view.

Nowadays, sustainability has become of increasing concern in policy and the decision making of stakeholders. Companies have been increasing their attention to their environmental performance. In order to measure sustainability performance, different approaches have been proposed.

Joint carbon footprint assessment and data envelopment analysis for the reduction of greenhouse gas emissions in agriculture production.

Operations management tools are critical in the process of evaluating and implementing action towards a low carbon production. Currently, a sustainable production implies both an efficient resource use and the obligation to meet targets for reducing greenhouse gas (GHG) emissions. The carbon footprint (CF) tool allows estimating the overall amount of GHG emissions associated with a product or activity throughout its life cycle.
