“…Apart from the efficiency assessment, the study examined a relationship between environmental efficiencies and economic growth in attaining sustainability. Djordjević et al (2018) employed a non-radial DEA model for an evaluation of railway efficiency of European countries regarding a level of safety at railway level crossings. Laurinavičius and Rimkuvienė (2017) using DEA provided results on the analysis of agricultural sectors efficiency of 28 EU member states (for 2010-2014).…”

Measuring sustainable development requires multidimensional attitude as the process is characterised by compound relationships between social, economic and environmental spheres. The paper aims at assessing selected effects of sectoral employment for the three dimensions of developmental processes. We examine employment efficiency in 25 EU countries concerning four sectors: agriculture, industry, market services, and non-market services. We use a non-radial DEA input-oriented model, which allows the assessment of the general efficiency of labour resources, as well as the evaluation of in-depth efficiency in the three dimensions of the economies under study. The novelty of the research lays in both multidimensional attitudes to the effects of labour engagement as well as intersectoral comparisons of the employment results. We categorise the EU countries according to efficiency in gaining the sustainable development and its three dimensions. Generally, the "old" EU members are of higher efficiency than the "new" states. Our research shows desirable movements of labour force that are necessary to improve efficiency and thus offers some advice for a rational development policy. It appears that it is necessary to limit agricultural employment in favour of non-market and market services and, to a lower extent, of industry. We conclude that the structural changes in employment specified by patterns observed in the highly developed EU countries are favourable for realising the aims of sustainable development.

“…Based on the obtained results by the application of the DEA method, DMUs are classified as efficient or non-efficient. One of the advantages of the DEA method is that it does not require any prior assumptions on underlying functional relationships between inputs and outputs [7]. The mathematical formulation of the classical input oriented Charnes, Cooper, and Rhodes (CCR) DEA model [111] can be written as:…”

“…However, in some real applications, the production process may also use undesirable inputs and generate undesirable outputs. However, a method for treating both undesirable inputs and outputs simultaneously in non-radial DEA models has been introduced by Djordjević et al [7]. One non-radial DEA model was presented by Wu et al [113] in the field of energy and environmental efficiency.…”

Considering the ability of the DEA method in efficiency evaluation and the advantages of the non-radial DEA model, the proposed model M has been chosen for application and evaluation in SC.…”

Supply Chain Management (SCM) represents an example of a complex multi-stage system. The SCM involves and connects different activities, from customer’s orders to received services, all with the aim of satisfying customers. The evaluation of a particular SCM is a complex problem because of the internally linked hierarchical activities and multiple entities. In this paper, the introduction of a non-radial DEA (Data Envelopment Analysis) model for the evaluation of different components of SCM, primarily in terms of sustainability, is the main contribution. However, in order to confirm the novelty and benefits of this new model in the field of SCM, a literature review of past applications of DEA-based models and methods are also presented. The non-radial DEA model was applied for the selection and evaluation of the environmental efficiency of suppliers considering undesirable inputs and outputs resulting in a better ranking of suppliers. Via perturbation of the data used, behavior, as well as the benefits and weaknesses of the introduced model are presented through sensitivity analysis.

The level crossings in the United States experience a significant number of accidents every year. The accidents can be reduced with the application of various countermeasures (e.g., traffic signal preemption, flashing lights, barrier cubs, gates). However, the application of countermeasures for all the level crossings in the United States is not feasible due to monetary limitations. Moreover, each countermeasure has a unique level of effectiveness and installation cost (e.g., the most effective countermeasures are typically more expensive than the least effective ones). Hence, selection of potent and cost-effective countermeasures at the riskiest level crossings is imperative to improve safety. While improving safety at level crossings with the
