A robust optimization model for sustainable and resilient closed-loop supply chain network design considering conditional value at risk
Lotfi, Reza; Mehrjerdi, Yahia Zare; Pishvaee, Mir Saman; Sadeghieh, Ahmad; Weber, Gerhard Wilhelm (2021-06-01)
One of the challenges facing supply chain designers is designing a sustainable and resilient supply chain network. The present study considers a closed-loop supply chain by taking into account sustainability, resilience, robustness, and risk aversion for the first time. The study suggests a two-stage mixed-integer linear programming model for the problem. Further, the robust counterpart model is used to handle uncertainties. Furthermore, conditional value at risk criterion in the model is considered in orde...
A robust fuzzy approach for constrained multi-product economic production quantity with imperfect items and rework process
Khalilpourazari, Soheyl; Mirzazadeh, Abolfazl; Weber, Gerhard Wilhelm; Pasandideh, Seyed Hamid Reza (Informa UK Limited, 2019-06-28)
This paper aims to develop a robust multi-item EPQ formulation considering rework process and imperfect items. The mathematical model consists of two objective functions targeting minimization of total inventory costs and the total required warehouse space, respectively. Since, in real-world applications, parameters of the mathematical formulation are due to uncertainty, in this paper, Basic Chance Constraint Programming and Robust Fuzzy Chance Constraint Programming models are developed to handle uncertain...
A Knowledge based approach in GMTI for the estimation of the clutter covariance matrix in space time adaptive processing
Anadol, Erman; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2012)
Ground Moving Target Indication (GMTI) operation relies on clutter suppression techniques for the detection of slow moving ground targets in the presence of strong radar returns from the ground. Space Time Adaptive Processing (STAP) techniques provide a means to achieve this goal by adaptively forming the clutter suppression filter, whose parameters are obtained using an estimated covariance matrix of the clutter data. Therefore, the performance of the GMTI operation is directly a ected by the performance o...
A Concept Filtering Approach for Diverse Density to Discover Subgoals in Reinforcement Learning
DEMİR, ALPER; Cilden, Erkin; Polat, Faruk (2017-11-08)
In the reinforcement learning context, subgoal discovery methods aim to find bottlenecks in problem state space so that the problem can naturally be decomposed into smaller subproblems. In this paper, we propose a concept filtering method that extends an existing subgoal discovery method, namely diverse density, to be used for both fully and partially observable RL problems. The proposed method is successful in discovering useful subgoals with the help of multiple instance learning. Compared to the original...
A Probabilistic Approach for Indirect Elicitation of the Preferences of a Decision Maker
Yet, Barbaros (2018-05-28)
Eliciting the preferences of a Decision Maker (DM) is a challenging task in multi criteria-decision making problems. DM preferences can be represented in the form of weights for criteria. Direct elicitation methods can be cognitively difficult for the DM especially when a large number of weights with close values are available. Indirect methods are beneficial in this regard as they use decision alternatives rather than weights for elicitation. However, the accuracy of these approaches can vary depending on ...
