Spare Parts On Demand Using Additive Manufacturing : A Simulation Model For Cost Evaluation., Stefan Jedeck

Electronic Theses and Dissertations

Little is known about the impact of additive manufacturing in the spare part supply chain. A few studies are available, but they focus on specific parts and their applications only. A general model, which can be adapted to different applications, is nonexistent. This dissertation proposes a decision making framework that enables an interested practitioner/manager to decide whether using additive manufacturing to make spare parts on demand is economical when compared to conventional warehousing strategy. The framework consists of two major components: a general discrete event simulation model and a process of designing a wide range of simulation scenarios. The goal …

Safe Operations Above Fl600, Lt. Col. Stephen Hunter

Space Traffic Management Conference

Safe Operations Above FL600

Abstract

With the increase in likelihood of near-term development of revenue-generating point-to-point suborbital flights and the increase in high-altitude-long-endurance commercial operations above FL600, the criticality of addressing operations above class A airspace has never been more pressing. While the Federal Aviation Administration describes the National Airspace System, it doesn’t offer a description that includes a top. Technological, physiological, physical and administrative limitations have relegated most air operations to FL600 and below. As that changes, previous work on Space Traffic Management (STM) concepts begin to take on new life and add to sincere considerations for adaptation or …

Using A Work System Metamodel And Usdl To Build A Bridge Between Business Service Systems And Service Computing, Steven Alter, Alistair Barros

Business Analytics and Information Systems

This paper explores the support for more comprehensive modeling of service systems than that possible through modeling methods developed through partial perspectives, with uncertainties about their wider suitability and need for integration with other methods in this domain. It responds to a Dual Call for Papers from INFORMS Service Science and IEEE Transactions on Service Computing requesting contributions that address the barely explored challenge of establishing links between business views of service systems and more technical views from service computing. Competing definitions of service reveal that most business views of service emphasize acts or outcomes produced for others, whereas a …

Application Of Goldratt’S Thinking Process To Constraints Within An Emergency Department—A Case Study, Augustine O. Amonge

Masters Theses & Specialist Projects

Emergency department (ED) acts as a feeder to many hospitals as it determines a large proportion of admissions. ED also acts as a buffer zone for many patients who cannot get care in other institutions due to insurance issues. Most hospitals are trying to invest heavily on their EDs, but cannot meet patients’ satisfaction in terms of cost and quality of care. There is great need for EDs to understand customers’ expectation given the rising cost of healthcare.

The focus of this study is at an ED center in Bowling Green Kentucky, using theory of constraints (TOC) thinking process application …

Dynamic Project Time And Cost Evaluation Under The Combined Influence Of Contract, Quality, And Uncontrollable Change, Thomas V. Hammock

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation proposes a method that quantifies the dynamics caused by disruptions due to multiple changes that can occur during the progression of a large scale project. To begin, equations consisting of multiple parallel event sequences are derived that define the relationship between individual process events and the final project completion time. Matrix notation and a precedence matrix concept are used in this derivation to produce equations that are best suited for computer programming applications. This relationship is the foundation upon which the equations are built to calculate the variation impact on each event of a large scale project. Pursuing …

Factors Affecting Dimensional Precision Of Consumer 3d Printing, David D. Hernandez

International Journal of Aviation, Aeronautics, and Aerospace

This paper investigates the factors affecting dimensional precision of consumer-grade 3D printing, attempting to isolate and mitigate sources of error. The focus is on creating engineering prototypes of, tooling for, or finalized instances of mechanical devices. A specific fused deposition modeling printer – the Ultimaker 2 – is analyzed in terms of meeting precise physical dimensions, consistent shapes, and predictable surface finish. Extensive trial and error resulted in removal of several sources of bias, with square test articles exhibiting a lower-than-anticipated mean percentage error of -0.387% (SD = 0.559), a value comparable to other modern manufacturing techniques.

Green Supply Chain Management In Chinese Electronic Manufacturing Organisations; An Analysis Of Senior Managements’ Perceptions., Eoin Plant, Yusen Xu, Gareth R.T. White

Articles

Green supply chain management and reverse logistics has emerged as a key area of research interest. Recent environmental regulations have also stimulated interest in this field. However, information sharing is a pre- requisite to efficient and effective logistics utilisation. Manufacturing organisations in China were argued to be 10-20 years behind their Western counterparts in relation to information sharing in their supply chains (Li and Yuan, 2009). This barrier needs to be addressed if China is going to maintain and grow its manufacturing position in the world, attempt to address green supply chain issues and their negative externalities. A systematic literature …

Construction Degree Graduates: An Evaluation Of Depth Of Skill Understanding And Skill Priority By Construction Industry Professionals, Ben F. Bigelow, Edelmiro Escamilla, Lauren Kuecker

The Professional Constructor

Previous studies have been conducted to determine the skills the construction industry expects graduates and entry level professionals to possess. The majority of those studies report soft skills and technical expertise as the main qualities graduates should have upon entering the industry. Many differing skills have been reported, but neither the expected depth of understanding in those skills nor the industry’s priority of those skills have been explored. To do so, a survey was administered to members of the Construction Industry Advisory Council at Texas A&M University asking these questions. Depth of understanding was evaluated on a four level basis …

Steps within the framework are illustrated using five projects from three countries. This work assumes that the ultimate objective of the project is local operational sustainability with the NGO’s presence …

A Rolling Horizon Auction Mechanism And Virtual Pricing Of Shipping Capacity For Urban Consolidation Centers, Chen Wang, Hoong Chuin Lau, Yun Fong Lim

Research Collection School Of Computing and Information Systems

A number of cities around the world have adopted urban consolidation centers (UCCs) to address challenges of last-mile deliveries. At the UCC, goods are consolidated based on their destinations prior to their deliveries into city centers. Typically, a UCC owns a fleet of ecofriendly vehicles to carry out such deliveries. Shippers/carriers that make use of the UCC’s service hence no longer need to be restricted by timewindow and vehicle-type regulations. As a result, they retain the ability to deploy large trucks for the economies of scale from the source to the UCC which is located outside the city center. Furthermore, …
