Abstract

Study on the Two-dimensional Bin Packing Problem with unforeseen dimensional item changes - called disruptions - preventing efficient bin predictions and packing. The aim of the thesis is to develop a proactive and reactive algorithm through a metaheuristic to explore different scenarios and effects in regards to item classes, disruption types, enlargement cases, etc.

Abstract

Every year, the number of parcels transported increases significantly, partly due to the generalization of e-commerce. This increase results in an augmentation of ships, trucks and planes needed to transport all these packages. We study in the master thesis a possible improvement in the loading process, which might result in faster loading and more efficient storage in containers. This improvement comes from the combination of two very different areas, namely augmented reality and the container loading problem. First, a container loading algorithm is developed, allowing to take a large number of boxes and pack them in a container. This algorithm uses a placement heuristic as well as an improvement heuristic to optimize the result. This software will be run on a server and data must be stored in a database, and communication must be possible through an application programming interface (API).
Afterwards, the objective is to combine this algorithm with a program developed on Unity running on a Hololens device. This software allows to visualize and interact with the solution proposed by the packing algorithm and to allow a human operator to assemble the container according to the instructions issued.
In addition to these tools, we also developed a web interface and a box generator

Abstract

Discrete optimization is an important area of Applied Mathematics with a broad spectrum of applications in many fields. This book results from a Special Issue in the journal Mathematics entitled ‘Advances and Novel Approaches in Discrete Optimization’. It contains 17 articles covering a broad spectrum of subjects which have been selected from 43 submitted papers after a thorough refereeing process. Among other topics, it includes seven articles dealing with scheduling problems, e.g., online scheduling, batching, dual and inverse scheduling problems, or uncertain scheduling problems. Other subjects are graphs and applications, evacuation planning, the max-cut problem, capacitated lot-sizing, and packing algorithms.

Abstract

This research topic aims at enterprise-wide modeling and optimization (EWMO) through the development and application of integrated modeling, simulation and optimization methodologies, and computer-aided tools for reliable and sustainable improvement opportunities within the entire manufacturing network (raw materials, production plants, distribution, retailers, and customers) and its components. This integrated approach incorporates information from the local primary control and supervisory modules into the scheduling/planning formulation. That makes it possible to dynamically react to incidents that occur in the network components at the appropriate decision-making level, requiring fewer resources, emitting less waste, and allowing for better responsiveness in changing market requirements and operational variations, reducing cost, waste, energy consumption and environmental impact, and increasing the benefits. More recently, the exploitation of new technology integration, such as through semantic models in formal knowledge models, allows for the capture and utilization of domain knowledge, human knowledge, and expert knowledge toward comprehensive intelligent management. Otherwise, the development of advanced technologies and tools, such as cyber-physical systems, the Internet of Things, the Industrial Internet of Things, Artificial Intelligence, Big Data, Cloud Computing, Blockchain, etc., have captured the attention of manufacturing enterprises toward intelligent manufacturing systems.
