A mathematical model for customer lifetime value based offer management
(Springer, 2018)
Customers with prepaid lines possess higher attrition risk compared to postpaid customers, since prepaid customers do not sign long-term obligatory contracts and may churn anytime. For this reason, mobile operators have ...
A web-based decision support system for quality prediction in manufacturing using ensemble of regressor chains
(Springer, 2020)
In this study we construct a decision support system (DSS), which utilizes the production process parameters to predict the quality characteristics of final products in two different manufacturing plants. Using the idea ...
Optimizing steering of roaming traffic with a-number billing under a rolling horizon policy
(Springer, 2020)
In this study, we focus on single service steering international roaming traffic (SIRT) problem by considering telecommunication operators’ agreements and “a-number billing” while keeping service quality above a certain ...
A CART-based genetic algorithm for constructing higher accuracy decision trees
(SciTePress, 2020)
Decision trees are among the most popular classification methods due to ease of implementation and simple interpretation. In traditional methods like CART (classification and regression tree), ID4, C4.5; trees are constructed ...
Churn prediction for mobile prepaid subscribers
(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 ...
A decomposition based metaheuristic approach for solving rapid needs assessment routing problem
(Elsevier, 2021-09)
This paper proposes a decomposition based tabu search algorithm for solving multi-cover routing problem in the case of rapid need assessment. Rapid needs assessment aims to evaluate impact of a disaster at different sites ...
Optimal pricing and inventory strategies for fashion products under time-dependent interest rate and demand
(Elsevier, 2021-04)
In this work we consider the dynamic pricing problem of a retailer operating in a market with a single fashion item and under time-dependent interest rate. The demand is assumed to be deterministic and dependent on the ...
A data-driven matching algorithm for ride pooling problem
(Elsevier, 2022-04)
This paper proposes a data-driven matching algorithm for the problem of ride pooling, which is a transportation mode enabling people to share a vehicle for a trip. The problem is considered as a variant of matching problem, ...
Robust parameter design and optimization for quality engineering
(Springer, 2022-03)
This paper proposes a methodology to determine the optimal settings of key decision variables that affect the resilience of an engineering design against uncertainty. Uncertainty in quality engineering is often caused by ...
Economic lot sizing problem with tank scheduling
(Elsevier, 2023-07-01)
We introduce a multiple-item economic lot sizing problem where items are produced through the fermentation of some raw materials. Fermentation takes place in specialized tanks that have finite capacities, and duration of ...
