A chance constraint based multi-item production planning model using simulation optimization
Albey, Erinç; Uzsoy, R.; Kempf, K. G. (IEEE, 2016)We consider a single stage multi-item production-inventory system under stochastic demand. We had previously proposed a production planning model integrating ideas from forecast evolution and inventory theory to plan work ... -
Churn prediction for mobile prepaid subscribers
Can, Zehra; Albey, Erinç (Institute for Systems and Technologies of Information, Control and Communicatio, 2017)In telecommunication, mobile operators prefer to acquire postpaid subscribers and increase their incoming revenue based on the usage of postpaid lines. However, subscribers tend to buy and use prepaid mobile lines because ... -
Collaborative prepositioning network design for regional disaster response
Koyuncu, Burcu Balçık; Silvestri, S.; Rancourt, M.‐È.; Laporte, G. (Wiley, 2019-10)We present a collaborative prepositioning strategy to strengthen the disaster preparedness of the Caribbean countries, which are frequently hit by hurricanes. Since different subsets of countries are affected in each ... -
Combining and solving sequence dependent traveling salesman and quadratic assignment problems in PCB assembly
Alkaya, A. F.; Duman, Ekrem (Elsevier, 2015-09-10)In this study we undertake the optimization of chip shooter component placement machines which became popular in assembling printed circuit boards (PCB) in recent years. A PCB is usually a rectangular plastic board on which ... -
A computational study of lower bounds for the two dimensional bin packing problem
Serairi, M.; Haouari, Mohamed (Elsevier, 2010-08-01)We survey lower bounds for the variant of the two-dimensional bin packing problem where items cannot be rotated. We prove that the dominance relation claimed by Carlier et al. between their lower bounds and those of Boschetti ... -
A continuous approximation approach for assessment routing in disaster relief
Huang, M.; Smilowitz, K. R.; Koyuncu, Burcu Balçık (Elsevier, 2013-04)In this paper, we focus on the assessment routing problem which routes teams to different communities to assess damage and relief needs following a disaster. To address time-sensitivity, the routing problem is modeled with ... -
Cost allocation mechanisms in a peer‐to‐peer network
Özener, Başak Altan; Özener, Okan Örsan (Wiley, 2019-01)This study analyzes a cooperative game between a service provider and a set of users. We consider a P2P network where the service provider broadcasts the content across the network and the users collaborate to seed the ... -
A cost-sensitive decision tree approach for fraud detection
Sahin, Y.; Bulkan, S.; Duman, Ekrem (Elsevier, 2013-11-01)With the developments in the information technology, fraud is spreading all over the world, resulting in huge financial losses. Though fraud prevention mechanisms such as CHIP&PIN are developed for credit card systems, ... -
Çevik yöntemlerde cosmic i̇şlev puanı ve hikaye puanının birlikte kullanımı
Ertaban, C.; Gezgin, S.; Bağrıyanık, S.; Albey, Erinç; Karahoca, A. (CEUR-WS, 2017)Hikaye Puanı (SP: Story Point), Scrum ve Kanban gibi çevik yöntemlerde kullanılan en yaygın metriklerden birisidir. Subjektif bir metrik olsa da kullanışlı ve basit olması nedeniyle çevik ekiplerin birikim listelerinde ... -
Decision rule bounds for two-stage stochastic bilevel programs
Yanıkoğlu, İhsan; Kuhn, D. (Society for Industrial and Applied Mathematics Publications, 2018)We study two-stage stochastic bilevel programs where the leader chooses a binary here-and-now decision and the follower responds with a continuous wait-and-see decision. Using modern decision rule approximations, we construct ... -
Delegation vs. control of component procurement under asymmetric cost information and simple contracts
Kayış, Enis; Erhun, F.; Plambeck, E. L. (Informs, 2013)A manufacturer must choose whether to delegate component procurement to her tier 1 supplier or control it directly. Because of information asymmetry about suppliers’ production costs and the use of simple quantity discount ... -
Developing a collaborative planning framework for sustainable transportation
Özener, Okan Örsan (Hindawi Publishing, 2014)Currently, as being the highest petroleum consuming sector in the world, transportation significantly contributes to the total greenhouse gas emissions in the world. Road transportation not only is responsible for approximately ... -
Development of lower bounds for the scheduling of setup tasks in serial production lines
Pessan, C.; Neron, E.; Haouari, Mohamed (Inderscience Publishers, 2013)Efficient production resettings are necessary to achieve production flexibility. For this reason, it is of primary importance to reduce the setup time required to switch the production from one product type to another, and ... -
Disaster preparedness using risk-assessment methods from earthquake engineering
Battarra, M.; Koyuncu, Burcu Balçık; Xu, H. (Elsevier, 2018-09-01)Analyzing the uncertainties associated with disaster occurrences is critical to make effective disaster preparedness plans. In this study, we focus on pre-positioning emergency supplies for earthquake preparedness. We ... -
Discrepancy search for the flexible job shop scheduling problem
Hmida, A. B.; Haouari, Mohamed; Huguet, M.-J.; Lopez, P. (Elsevier, 2010-12)The flexible job shop scheduling problem (FJSP) is a generalization of the classical job shop problem in which each operation must be processed on a given machine chosen among a finite subset of candidate machines. The aim ... -
Discrete time/cost trade-off problem: a decomposition-based solutionalgorithm for the budget version
Hazır, Ö.; Haouari, Mohamed; Erel, E. (Elsevier, 2010-04)This paper investigates the budget variant of the discrete time/cost trade-off problem (DTCTP). This multi-mode project scheduling problem requires assigning modes to the activities of a project so that the total completion ... -
The effect of multiple operating room scheduling on the sterilization schedule of reusable medical devices
Göktürk, Elvin Çoban (Elsevier, 2020-09)We study scheduling problems of operating rooms (ORs) and sterilization of reusable medical devices (RMDs) where RMDs are the tools that have to be sterilized in order to be reused in the other surgeries. During their ... -
Energetic reasoning revisited: application to parallel machine scheduling
Hidri, L.; Gharbi, A.; Haouari, Mohamed (Springer Science+Business Media, 2008-08)We consider the problem of minimizing makespan on identical parallel machines subject to release dates and delivery times. We present several new feasibility tests and adjustment techniques that consistently improve ... -
Enhanced energetic reasoning-based lower bounds for the resource constrained project scheduling problem
Haouari, Mohamed; Kooli, A.; Neron, E. (Elsevier, 2012-05)We present new and effective lower bounds for the resource constrained project scheduling problem. This problem is widely known to be notoriously difficult to solve due to the lack of lower bounds that are both tight and ... -
