In the context of intelligent maintenance, spare part prediction business scenario seeks promising return-on-investment (ROI) by radically diminishing the hidden costs at after-sales customer services. However, the classification of class-imbalanced data with mixed type features at this business scenario is not straightforward. This paper proposes a hybrid classification model that combines C4.5, Apriori algorithms and weighted k-Nearest Neighbor (kNN) adaptations to overcome potential shortcomings observed at the corresponding business scenario. While proposed approach is implemented within CRISP-DM reference model, the experimental results demonstrate that proposed approach doubles the human-level performance at spare part prediction. This highlights a 50% decrease at the average number of customer visits per fault incident and a significant cutting at the relevant sales and distribution costs. According to best runtime configuration analysis, a real-time spare part prediction model has been deployed at the client's SAP system

Comparison of lead time quotation policies in e-commerce environment
Altuntaş, Ecem; Duran, Serhan; Department of Industrial Engineering (2019)
This research is based on problems faced by e-commerce firms while determining lead time for their customers. It is hard to obtain an optimal policy for the tradeoff between serving on-time and quoting short lead times. On-time customer services are positively correlated with rating scores of firms in e-commerce websites. Therefore, in this study, the fluctuation of on-time customer service proportion is used as the main determinant of the rating of the firms and different policies of lead time quotation ar...
UNCERTAINTY CALCULATION-AS-A-SERVICE: AN IIOT APPLICATION FOR AUTOMATED RF POWER SENSOR CALIBRATION
Çetinkaya, Anıl; Kaya, Muhammed Çağrı; Danaci, Erkan; Oğuztüzün, Mehmet Halit S. (2022-01-01)
Providing automated and networked solutions on the cloud will remarkably facilitate ongoing digitalization efforts in Metrology and the calibration industry. The AutoRFPower application was developed to automate the RF power measurement process and uncertainty calculations. This study presents our ongoing research on moving this application to a cloud environment and adapting it to perform power sensor calibrations. The cloud-based application initiates communication with calibration equipment, transfers te...
Robust conditional value–at–risk under parallelpipe uncertainty: an application to portfolio optimization
Kara, Güray; Weber, Gerhard Wilhelm; Department of Financial Mathematics (2016)
In markets with high uncertainties, the trade–off between maximizing expected return and minimizing the risk is one of the main challenges in modeling and decision making. Since investors mostly shape their invested amounts towards certain assets and their risk version level according to their returns; scientists and practitioners has done studies on this subject since the beginning of the stock markets’ establishment. Developments and inventions in the mathematical optimization provide a wide range of solu...
An empirical comparison of customer behavior modeling approaches for shopping list prediction
Peker, Serhat; Koçyiğit, Altan; Eren, Pekin Erhan (2018-06-28)
Shopping list prediction is a crucial task for companies as it can enable to provide a specific customer a personalized list of products and improve customer satisfaction and loyalty as well. To predict customer behaviors, many studies in the literature have employed customer behavior modeling approaches which are individual-level and segment-based. However, previous efforts to predict customers' shopping lists have rarely employed these state-of-the-art approaches. In this manner, this paper introduces the...
Value-based risk management in defense projects pricing with a robust optimization approach
Aker, Kerime Özge; Meral, Fatma Sedef; Department of Industrial Engineering (2015)
In this study, we address the bid pricing problem of a defense company facing with supply chain and financial risks due to long-term project planning. Creating shareholder value has become a quite popular topic in business as value-adding companies are the only ones to survive in the market. We formulate the problem as a value-based performance and risk management model through robust optimization approach in order to cope with various ambiguities over project lifecycle with possible discrete scenario set. ...
