Belief space planning is concerned with the problem of finding the control policy under process and measurement uncertainties. Formulated as a stochastic control problem, the solution of a general Decentralized Partially Observed Markov Decision Process (Dec-POMDP) is a collection of feedback policies for individual agents, maximizing a joint value function. In this paper, we design (m) number of...
Planning under motion and observation uncertainties requires the solution of a stochastic control problem in the space of feedback policies. In this paper, by restricting the policy class to the linear feedback polices, we reduce the general (n2 + n)-dimensional belief space planning problem to an (n)-dimensional problem. As opposed to the previous literature that search in the space of open-loop...
Technology localization is a popular policy in developing countries to reduce the dependency on foreign partners of the industrial manufactures. In this paper, we present a model to analyze the determinant parameters of technology localization process. The model is based on the system dynamics methodology. Our results show that the technology localization becomes stable after a period of time.
Planning under process and measurement uncertainties is a challenging problem. In its most general form, it can be modeled as a Partially Observed Markov Decision Process (POMDP) problem. However POMDPs are generally difficult to solve when the underlying spaces are continuous, particularly when beliefs are non-Gaussian, and the difficulty is further exacerbated when there are also non-convex constraints...
Iran's economy has always been under severe sanctions. These sanctions were almost tolerable for Iran since they did not affect Iran's oil industry which is the main source of foreign currency for the country. The recent sanctions on Iran's oil-dependent economy starting from 2012, put a lot of pressure on the country and the overall country experienced very volatile conditions. As the result, the...
The uncontrolled climate change is one of the most significant threats to the sustainable development of the human societies. Since the establishment of the Kyoto Protocol in 1997, several models have been proposed to limit the emission of Greenhouse Gases (GHGs) by trying to enforce abiding regulations to the participating countries. One of the successful implementations of such models is the Emission...
International Community can decide to establish several types of sanctions on the economy of a country. No matter the reasons of these sanctions, generally, they can have many adverse effects on the economy of the sanctioned country. This depends on the variety and extent of the sanctions. We propose a system dynamics model to capture some of the main reasons behind the economic instability in a sanctioned...
