در این پژوهش وضعیت صنایع در کشور ایران مورد ارزیابی و مقایسه قرار گرفته است . برای این منظور، بر مبنای طبقه بندی استاندارد بین المللی فعالیت های اقتصادی (i.s.i.c) زیرشاخه های دو رقمی صنایع مشخص شده و وضعیت این زیرشاخه ها بر اساس شاخص های منتخب اقتصادی مقایسه و تجزیه و تحلیل میشوند. جهت مقایسع بین زیرشاخه ها و تعیین عملکرد آنها روشهای تحلیل چندگانه بکار برده می شوند. روشهای تحلیل چندگانه به روشه...

Developing realistic models for the evaluation of sustainable supply chains has turned into a major challenge facing managers. The decision-making approaches proposed here consist of two stages. At the first stage, a dynamic-network data envelopment analysis (DNDEA) model is established for the first time, wherein the current efficiency of a business can be influenced by its prior social and en...

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...

data envelopment analysis (dea) is a technique that uses all collected observations to measure performance. this method presents no data about how to operate on dmu. the present research attempted to study a unit with all its subunits, if the unit is efficient, it means that all its subunits are efficient too and if it is an inefficient, it shows clearly that which one of the subunits makes ine...
