This paper addresses the filter design issues for multi-user cooperative non-regenerative MIMO relay systems in both downlink and uplink scenario. Based on the formulated signal model, the filter matrix optimization is first performed for direct path and relay path respectively, aiming to minimize the mean squared error (MSE). To be more specific, for the relay path, we derive the local optimal...

the aim of this study was to develop an optimal sustainable forest plantation based on goal programming and analytic hierarchy process (ahp) methods. this study was carried out in guilan province, north of iran. first of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological makhdoum model by m...

GOAL is a multi-agent programming language based on the BDI paradigm. It is a logic-based language that supports modular agent design based on established software engineering principles and interaction with environments using an environment interface standard (EIS). GOAL recently won the Multi-Agent Programming Contest (MAPC), where two teams consisting of ten agents play against each other in...

Scenario analysis within a multi-stage stochastic programming formulation offers an attractive framework for modelling uncertainties in long-range planning models. However, whether the expected outcome is implicitly / explicitly evaluated, such formulations lead to computationally intensive optimization problems. Focussing here on the scenario planning / multi-period approach for mixed integer ...

A new sensor-selection solution within a Multi-Bernoulli-based multi-target tracking framework is presented. The proposed method is especially designed for the general multi-target tracking case with no prior knowledge of the clutter distribution or the probability of detection, and uses a new task-driven objective function for this purpose. Step-by-step sequential Monte Carlo implementation of...

An effective way for managing and controlling a large number of inventory items or stock keeping units (SKUs) is the inventory classification. Traditional ABC analysis which based on only a single criterion is commonly used for classification of SKUs. However, we should consider inventory classification as a multi-criteria problem in practice. In this study, a new method of Evaluation based on ...

Modem competitive scenario necessitates the achievement of strategic fit between competitive and supply chain strategies, for effective and economic response in filling customer's orders, by a manufacturing enterprise. Towards this end, all the decisions (strategic, planning and operational) with regard to supply chain ought to be in conformity with strategic fit zone along cost efficiency and ...

This paper focuses on the general problem of coordinating multiple robots. More specifically, it addresses the self-election of heterogeneous specialized tasks by autonomous robots, as opposed to the usual multi-tasks allocation problem in multi-robot systems in which an external controller distributes the existing tasks among the individual robots. In this work we are considering a specificall...

In this paper we propose a composite Variational Inequality formulation for modeling multi-mode, multi-class and multi-criteria stochastic dynamic user equilibrium problem in recurrent congestion network with queues. The each mode of travelers is classified into two classes. One is the equipped traveler following stochastic dynamic user-equilibrium with less uncertainty of travel cost, another ...
