this paper presents a deterministic approach for performance assessment of different province’s road safety level at iran. a data envelopment analysis (dea) model considering undesirable input and output indices and a multivariate statistical method, principle component analysis (pca) are used in this paper, while previous studies do not use composite pca-dea method and undesirable input and ou...

in the present study, an application of multilevel modeling approach to the input- output analysis are presented first, the regional input-output table of all provinces in iran was extracted based on the adjusted flegg location quotient method (aflq). second differentiation in the leontief technical coefficients and the backward and forward linkages among various activities and sectors of all p...

data envelopment analysis (dea) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (dmus) where multiple inputs and outputs exist. in the conventional applications of dea, the data are considered as specific numerical values with explicit designation of being an input or output. however, the observed values of the data are sometimes imprec...

Structural parameter identifiability is a property of differential model with parameters that allows for the to be determined from equations in absence noise. One standard approaches assessing this problem via input–output and, particular, characteristic sets ideals. The precise relation between and subtle. goal note clarify relation. main results are: We expect some these facts may known exper...

regional input-output tables historical background goes back to 1950 when its idea was proposed by walter isard. in iran, regional accounts generation started in the fifth development plan before the islamic revolution, but these accounts have been generated only for some provinces. the generation and completion of these accounts and tables on the basis of surveying and mechanical methods or a ...
