Fuzzy dynamic input–output inoperability model
International Journal of Critical Infrastructure Protection, 2011Abstract This paper describes an extension of the input–output inoperability model (IIM) that accommodates uncertain and vague data. In the resulting “fuzzy version” of the dynamic IIM model (FD-IIM), the level of inoperability of each infrastructure and the Leontief coefficients are specified using fuzzy variables that express expert knowledge about

Agent-based input–output interdependency model
International Journal of Critical Infrastructure Protection, 2010Abstract The modeling and analysis of critical infrastructures and their interdependencies are essential to discovering hidden vulnerabilities and the related threats to national and international security. Over the past few years, several approaches have been proposed to address this problem. The so-called holistic approaches are relatively abstract,

Input-Output+Econometric and Econometric+Input-Output: Model Differences or Different Models?
1998Integrated input-output and econometric models are becoming increasingly widespread. The integrated model attempts to model the dynamic (lagged) time path of the economy which may be in a continual state of disequilibrium as it tracks toward continually shifting equilibria, therefore providing a more realistic picture of the dynamic characteristics of ...

In chapter 2, we set forth the economic base model and the accounts that accompany it. In the next three chapters, we developed the single-industry model further. To develop a usable regional model, we now expand our purview and consider multiple-industry models.

Focus on expansion of a classical input-output model, this chapter introduces a fuzzy input-output model first, then inquires an input-output model with T-fuzzy data and its application, and presents an input-output model with triangle fuzzy data finally.

Disaggregating Input-Output Models [PDF]
, 2014 This Technical Document describes the steps to disaggregate an industry sector in an I-O table using Python. A disaggregation method that based on weight factors is used in this document. The calculation has three parts. The first part is to calculate the disaggregated input matrix DIM, which represents all the input from common sectors into the new ...

Volkswirtschaftliche Input-Output-Modelle
1972In den folgenden Ausfuhrungen werden einleitend produktionstheoretische Begriffe und Annahmen der behandelten Modelle diskutiert. Ausgehend von allgemeinen okonomischen Modellvoraussetzungen und Definitionen wird dann das Input-Output-Grundmodell von LEONTIEF in Form eines Produktions- und Preismodells entwickelt.

Stochastic input-output modeling
Managerial Economics, 2007Input-output data (IO data) are compiled by survey methods, which are based on a sample. It is well known, that IO matrices are not stable overtime. Therefore different actualizations methods have been developed. Econometric methods play important role in the realization of input-output matrices.
