Evolving hybrid deep neural network models for end-to-end inventory ordering decisions
Moraes, Thais de Castro; Qin, Jiancheng; Yuan, Xue-ming; … - In: Logistics 7 (2023) 4, pp. 1-18
Background: Over the past decade, the potential advantages of employing deep learning models and leveraging auxiliary data in data-driven end-to-end (E2E) frameworks to enhance inventory decision-making have gained recognition. However, current approaches predominantly rely on feed-forward...

An ensemble learning model for predicting the intention to quit among employees using classification algorithms
Biswas, Ashish Kumar; Seethalakshmi, R.; Mariappan, Prabha - In: Decision analytics journal 9 (2023), pp. 1-13
Employees are often more likely to use social media for job searching, which sometimes causes withdrawal behaviour. This study proposes an ensemble learning model for predicting the intention to quit (IQ) based on selected features, such as job Involvement (JI), organizational commitment (OC),...

A step-size follow-the-leader optimization algorithm with an improved step parameters
Singh, Priyanka; Kottath, Rahul - In: Decision analytics journal 9 (2023), pp. 1-16
Follow the leader (FTL) algorithm is a newly developed optimization algorithm inspired by a sheep's movement within a flock. FTL has been successfully implemented to solve power prediction problems. However, the probability of falling in local optima is high due to randomness in the step...

A Hybrid Particle Whale Optimization Algorithm with application to workflow scheduling in cloud-fog environment
Bansal, Sumit; Aggarwal, Himanshu - In: Decision analytics journal 9 (2023), pp. 1-14
Workflow scheduling aims to optimize task allocation and execution in cloud-fog​ computing environments. Finding an optimal algorithm for workflow scheduling poses a significant challenge due to the complexity and variability of tasks and resources involved. Although meta-heuristic algorithms...

A crossover-based multi-objective discrete particle swarm optimization model for solving multi-modal routing problems
Afrasyabi, Parastoo; Mesgari, Mohammad Saadi; … - In: Decision analytics journal 9 (2023), pp. 1-17
Passengers must use a set of modes and vehicles to reach their destination in complicated urban structures. Choosing an optimal route is a complicated optimization problem for these passengers. This study proposes a multi-objective optimization algorithm to solve the routing problem in the urban...
