Over the past two decades, use of network data envelopment analysis in real-world issues has attracted attention many researchers. This is used when output results a decision unit are as input to later units. Uncertainty inputs and outputs each complicates performance evaluation such systems. In this paper, new model heterogeneous hybrid developed measure efficiency units assuming open structur...

in this paper, we introduce a model  to optimization of milk run system that is one of vrp problem with time window and uncertainty in inventory. this approach led to the routes with minimum cost of transportation while satisfying all inventory in a given bounded set of uncertainty .the problem is formulated as a robust optimization problem. since the resulted problem illustrates that grows up ...

feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of local binary pattern features. in this paper, we investigate the use of local binary patterns for percep...

Many robust control problems can be formulated in abstract form as convex feasibility programs, where one seeks a solution x that satisfies a set of inequalities of the form F . = {f (x, ) 0, ∈ D}. This set typically contains an infinite and uncountable number of inequalities, and it has been proved that the related robust feasibility problem is numerically hard to solve in general. In this pap...

In this study, a high-efficiency wireless power transfer (WPT) coil that is robust against interoperability and misalignment was developed by applying an inductive system to drone. The transmitting had ferrite plate applied helical structure included the receiving part. guard-type part sheet. To analyze spiral coils according winding method, z-axis magnetic field vector analyzed. A suitable WPT...
