A supply chain analytics approach for optimizing milk collection routing in multi-depot networks
Neroni, Mattia; Rinaldi, Marta - In: Supply chain analytics 10 (2025), pp. 1-18
This study presents a supply chain model for optimizing milk collection routing in multi-depot networks. The problem consists of a fleet of vehicles that leaves their depots (i.e., typically the driver's houses), visits an assigned set of farms to collect the raw milk, and delivers it to the...

Algorithmic trading system with adaptive state model of a binary-temporal representation
Stasiak, Michal Dominik - In: Risks : open access journal 13 (2025) 8, pp. 1-12
In this paper a new state model is introduced, an adaptative state model in a binary temporal representation (ASMBRT) as well as its application in constructing an algorithmic trading system. The presented model uses the binary temporal representation, which allows for a precise analysis of...

An integrated analytics model for supplier selection and order allocation with machine learning and multi-criteria optimization
Hayati, Enty Nur; Jauhari, Wakhid Ahmad; Damayanti, Retno; … - 2025
Sustainable Supplier Selection and Order Allocation (SSSOA) are critical strategic decisions in supply chain management. The decision-making process becomes complex under uncertainty, especially in a multi-supplier, multi-item, and multi-period environment. This study proposes a four-stage...

Bayesian estimation of two-parameter power Rayleigh distribution and its application
Irfan, Mohd; Sharma, Anup Kumar - In: Statistics in transition : an international journal of … 26 (2025) 3, pp. 59-79
This paper explores classical and Bayesian approaches to the estimation of unknown parameters and reliability functions for the power Rayleigh distribution. The maximum likelihood estimator (MLE) method is considered in classical estimation. The Bayesian estimation, on the other hand uses...
