Data Driven Efficiency for E-Warehousing: Descriptive and Prescriptive Analytics
(University of Waterloo, 2018-05-18)Based on data provided by a warehouse logistics management company, we analyze the warehousing operation and its major processes of order picking and order consolidation. Without access to the actual layouts and process ... -
A data-driven optimization approach for mixed-case palletization and three-dimensional bin packing
(University of Waterloo, 2018-01-18)Palletization is the most standard method of packaging and transportation in the retail industry. Their building involves the solution of a three-dimensional packing problem with side practical constraints such as item ... -
Data-driven Structure Detection in Optimization: Decomposition, Hub Location, and Brain Connectivity
(University of Waterloo, 2018-07-13)Employing data-driven methods to efficiently solve practical and large optimization problems is a recent trend that focuses on identifying patterns and structures in the problem data to help with its solution. In this ... -
A Feasible Lagrangian Approach with Application to the Generalized Assignment Problem
(University of Waterloo, 2019-01-28)Lagrangian relaxation is a widely used decomposition approach to solve difficult optimization problems that exhibit special structure. It provides a lower bound on the optimal objective of a minimization problem. On the ... -
Green Supply Chain Network Design with Emission Sensitive Demand
(University of Waterloo, 2019-04-30)Over the last few decades, the argument for a link between greenhouse gas emissions and global warming has become stronger. In response, there has been a global shift. Politicians are implementing carbon policies while ... -
Hierarchical and Nesting Approaches for the Facility Layout Problem
(University of Waterloo, 2018-08-16)The Facility Layout Problem (FLP) seeks to determine the dimensions, coordinates and arrangement of rectangular departments within a given facility. The goal is to minimize the cost of inter-department flow. It has several ... -
A Lagrangian Approach for The Airfreight Consolidation Problem Under Pivot-weight
(University of Waterloo, 2018-05-23)International airfreight forwarders are faced with the problem of consolidating ship- ments for efficient transportation by airline carriers. The use of standard unit loading devices (ULDs) is a solution adopted by the ... -
Models and Solution Methods for the Pallet Loading Problem
(University of Waterloo, 2018-05-07)The three-dimensional bin packing problem (3DBPP) seeks to find the minimum number of bins to pack a finite number of rectangular boxes. It has a wide array of applications, ranging from airline cargo transportation to ... -
PPE Distribution Planning and Capacity Acquisition During the COVID-19 Pandemic
(University of Waterloo, 2021-09-27)The COVID-19 pandemic caused disruptions to global supply chains and the uncer- tainty surrounding its progression has created challenges in distributing critical supplies such as personal protective equipment (PPE). We ... -
Strategic Blockchain Adoption in Supply Chain Operations
(University of Waterloo, 2021-12-17)Supply chains have often benefited from breakthroughs in information technology. Most recently, blockchain is promising to revolutionize the way supply chains are designed and operated. In this thesis, we explore blockchain ... -
Supply Chain Network Design with Concave Costs: Theory and Applications
(University of Waterloo, 2016-01-13)Many practical decision models can be formulated as concave minimization problems. Supply chain network design problems (SCNDP) that explicitly account for economies-of-scale and/or risk pooling often lead to mathematical ...
