An adaptive large neighborhood search for the multi-compartment inventory routing problem
Gültekin, Ceren (2021-06-10)In this thesis study, we concentrate on an inventory routing problem with a fleet of multi-compartment vehicles which enables the distribution of different products to customers on a delivery route. Using separate compartments ... -
An application for a particleboard plant: Web-based decision support system for quality prediction and digital transformation
As it is same for most of the production procedures, a certain quality level must be derived in the particle board production. In the particleboard production, a series of samples taken from the production line for the ... -
Economic lot sizing problem with tank scheduling
Dereli, Meryem Merve (2021-08)In this study, we consider an Economic Lot sizing Problem with Tank Scheduling (ELSTS). The problem is a real-world problem, which is generally found in fermented beverage and food facilities. A facility might produce an ... -
Mathematical modeling and math heuristic approach for shift selection, lot sizing and worker assignment problem of Vestel
The simultaneous lot sizing and scheduling studies do not implement a worker assignment problem in the literature. This study provides a solution for worker assignment problems with overtime constraints of the Government. ... -
A mathematical modelling approach for dled TV panel design
