This paper defines the production possibility set and constructs the multiple objective programming for matrix-type organization on the basis of the Charnes, Cooper and Rhodes (CCR) model. Then the efficiency score of the complex system can be calculated through solving the multiple objective programming. Compared with the traditional data envelopment analysis (DEA) model shows the new model ca...

Data Envelopment Analysis (DEA) is a methodology that computes efficiency values for decision making units (DMU) in a given period by comparing the outputs with the inputs. In many cases, there are some time lag between the consumption of inputs and the production of outputs. For a long-term research project, it is hard to avoid the production lead time phenomenon. This time lag effect should b...

In 2020, China put forward the goals of “peak carbon dioxide emissions” and “carbon neutrality” (“double-carbon”) it is urgent for energy industry to achieve green transformation. Aiming at rigid requirements carbon-peaking carbon-neutrality (“double-carbon”), this study established a performance evaluation index system an supply chain four-tier structure based on “double-carbon” goals, calcula...

one of the most popular approaches to measuring productivity changes is based on using malmquist productivity indexes. in this paper we propose a method for obtaining interval malmquist productivity index (impi). the classical dea models have been before used for measuring the malmquist productivity index. the current article extends dea models for measuring the interval malmquist productivity ...

This paper is aimed at evaluating the performance and efficiency of technical-vocational training colleges. This could pave the ground for improving the efficiency of these colleges and determining the right amount of budget they need. This paper tries to answer the questions about the ways of evaluation the efficiency of technical-vocational colleges of provincial capitals and improving the ef...

Some specific geometric data envelopment analysis (DEA) models are well known to the researchers in DEA through so-called multiplicative or log-linear efficiency models. Valuable properties of these models were noted by several authors but the models still remain somewhat obscure and rarely used in practice. The purpose of this paper is to show from a mathematical perspective where the geometri...

The importance of supplier selection is nowadays highlighted more than ever as companies have realized that efficient supplier selection can significantly improve the performance of their supply chain. In this paper, an integrated model that applies Data Envelopment Analysis (DEA) and Support Vector Machine (SVM) is developed to select efficient suppliers based on their predicted efficiency sco...

فنون و روش‌های ریاضی برنامه‌ریزی و تصمیم‌گیری اگر-چه جوابی بهینه را ارایه می‌دهند؛ اما تحت شرایط و مفروضات خاصی از این توانایی برخوردار هستند. علی‌رغم دامنه وسیع کاربرد تصمیم‌گیری‌های چند معیاره در دنیای واقعی، این رویکرد نیز محدودیت‌ها و چالش‌های خاص خود را دارد. رویه هایی نیز برای انتخاب متدمناسب وجود دارد که البته بعضا این رویه‌ها ابزاری برای حذف تکنیک-ها تا انتخاب تکنیک مناسب می‌شوند. در رو...

In this paper, we will propose a Slacks-Based measure (SBM) of efficiency in DEA. This scalar measure deals directly with the input surplus and the output shortage of the decision making unit (DMU) concerned. It is unit invariant and monotone decreasing with respect to input surplus and output shortage. Furthermore, this measure is decided only by consulting with the reference set of the DMU an...

More than 200 papers have been published in the last 20 years on the topic of health supply chains (HSC). Looking at the research methodologies employed, less than 15 papers apply data envelopment analysis (DEA) models. This is in contrast to, for example, A Network Data Envelopment Analysis (NDEA) Model for Supply Chain Performance Evaluation where several reviews on respective NDEA models hav...
