Stochastic Modeling of Dynamic Value Networks

Identification Code
Project Focus
Project Type (EU)
Publications ÚTIA
The proposed project deals with modeling and simulation of dynamic value networks, which are increasingly replacing the traditional vertically integrated enterprises. The project´s objective is to develop a stochastic model of the dynamic behavior of a value network, which would account for both the formation of a functioning network out of available nodes and the changes in performance of individual nodes over time. The proposed approach to modeling combines Ulf Grenander´s general pattern theory with stochastic extension of Jay Forrester´s system dynamics. Estimation of the network state and parameter values is formulated as the Bayesian inference problem, whose numerical solution is assumed using a sequential Monte Carlo algorithm. The model is generic enough to cover value networks in diverse industries. The project explores various definitions of the ´value´concept and the relationship between the value transformation over a specific node and the node performance characteristics.
