Evaluation of automated storage and retrieval in a distribution center
(Massachusetts Institute of Technology, 2020)
In the face of e-commerce growth and rising customer delivery expectations, companies must adapt to meet shorter contract shipping requirements with existing infrastructures. The "Amazon effect", an evolution resulting in ...
Reducing variations in a highly constrained environment in order to increase production capacity
(Massachusetts Institute of Technology, 2020)
Variations and the negatives effects it causes on production capacity and planning are topics of significant interest in the manufacturing communities. This research investigates the hypothesis that, when operating in a ...
Additive manufacturing applications and implementation in aerospace
(Massachusetts Institute of Technology, 2020)
Many aerospace companies are turning to additive manufacturing solutions to stream-line current production processes and open opportunities for on-demand producibility. While many OEMs are drawn to the appeal of the benefits ...
Organizational architecture design and assessment of statistical feasibility for FSDA implementation in an airplane subassembly
(Massachusetts Institute of Technology, 2020)
Boeing is a ubiquitous name and prominent leader in the aerospace industry, maintaining dominance in part by continuously seeking to improve. Boeing is now embracing a charter to become a Global Industrial Champion in ...
Modifiable stability and maneuverability of high speed unmanned underwater vehicles (UUVs) through bioinspired control fins
(Massachusetts Institute of Technology, 2020)
Underwater Vehicles generally have control fins located only near their aft end, for making controllable changes in directions. This design allows for stability of control; however, the turns are typically large in comparison ...
Design and development of a novel liquid desiccant air-conditioning system
(Massachusetts Institute of Technology, 2020)
The Direct Evaporative Closed Air Loop (DECAL) system is a novel high efficiency liquid desiccant air-conditioning (LDAC) system which runs primarily on thermal energy rather than electricity. It is designed for residential ...
Analysis of tool path optimization in large scale additive manufacturing
(Massachusetts Institute of Technology, 2020)
In large scale extrusion additive manufacturing, otherwise known as Big Area Additive Manufacturing (BAAM), systems, a heated extrusion will deposit thermoplastic material above its glass transition temperature along a ...
On the potential of convolutional neural networks for estimating the structural response of two-material structures
(Massachusetts Institute of Technology, 2020)
During the past years, the neural networks drew more and more interest from the solid mechanics community. In particular, they have proven to provide a powerful framework for constitutive modeling. This work takes first ...
Estimation of precursors for extreme events using the adjoint based optimization approach
(Massachusetts Institute of Technology, 2020)
We formulate a generalized optimization problem for a non-linear dynamical system governed by a set of differential equations. The plant under focus is the 2-D Kolmogorov flow, as this flow has inherent turbulence which ...
Incorporating contact management and marine dynamics in decentralized auction bidding for autonomous surface vehicles
(Massachusetts Institute of Technology, 2020)
This research studies techniques that can be applied to practical multi-task multi-vessel marine applications to manage mission planning for autonomous surface vehicles (ASVs). This thesis investigated the use of a ...
