Radio Frequency Identification (RFID) is an enabling technology that has been widely adopted in the retail industry. The powers of RFID are acknowledged by many, but a lack of understanding of the technology, its limitations, and how to select the right plan for its target installation has slowed efforts to migrate the technology into the aerospace, space, and transportation industries. While RFID is not a new technology, the rate at which it has been integrated into the aerospace industry has been slow due to unique considerations regarding qualification, regulations, and safety. New Department of Defense (DoD) policies requiring an integrated materiel supply chain process that fully supports military operational requirements will further advance the use of RFID technologies.

Presently, most of the companies have combination of process and product layout. Cellular manufacturing is a place where company has established one or more manufacturing cells. Due to competition, Automobile industries are changing existing plant layout to “Cellular Layout” in which manufacturing process is carried out by proper arrangement of machines. This research paper aims at the optimization of cellular manufacturing layout using: cell formation stage, cell layout stage. In the first stage, a heuristic based upon the material flow is developed, which allows the machines to be clustered more naturally. In the second stage, a genetic algorithm is used to optimize the machine layout within each cell, in which a previously defined material handling system is provided. This representation allows the design of the layout and aisle-structure simultaneously, and can be converted into a string representation adaptable by a genetic algorithm for optimization. The number of aisles in the optimized aisle-structure is also minimized.

Abstract Road train vehicles have been applied as one of the common and efficient ways for transportation of goods, specifically hazardous liquid cargos, in different nations. These vehicles have a wide variety of lengths and towing systems such as the fifth wheel or the dolly draw-bar. Based upon specific regulations, they could be authorized to move on specific roads. In order to avoid hazard and danger in case of accidents, safety performance of a B-train vehicle as a specific type of road train vehicles is investigated in this paper. A Multi-Body Dynamic (MBD) model, which consists of a prime mover and two trailers coupled by fifth wheels, are simulated in the initial phase of the study. The developed dynamic model is capable of simulating required tests as well as the SAE lane change, along with a constant radius turn for the purpose of roll and yaw stability analysis and safety evaluation. The effects of variation of the fluid fill level are considered in this research. The trammel pendulum concept is adopted for simulation of fluid movements, known as sloshing, in two articulated tankers of the model.

Abstract Remanufacturing is a process in which used products are disassembled, and their components are repaired and used in the production of new products. This study investigates the impact of various remanufacturing decisions on Original Equipment Manufacturer (OEM) profitability and market cannibalization in an infinite-horizon production scenario for heavy duty vehicle (HDV) clutches. A discrete event simulation model is developed for benchmarking of different scenarios using various factors and their levels. There are two consumer segments as primary customer and grey customer in the market. Three different end of life (EOL) clutch quality conditions are defined, and three different percentages of clutch collect strategies are defined for all EOL products in the market. Therefore, a total of nine combinations (i.e., three quality index and three collecting strategies) are benchmarked in terms of total profit from new and remanufactured HDV clutches, number of customers won, and amount of saved raw material for environmental considerations.

Abstract Fuel cells are a promising energy source on account of their high efficiency and low emissions. Proton exchange membrane fuel cells (PEMFC) are clean and environmental-friendly power sources, which can become future energy solutions especially for transport vehicles. They exhibit good energy efficiency and high power density per volume. Working at low temperatures (<90°C), hydrogen fuelled proton exchange membrane fuel cells (PEMFCs) are identified as promising alternatives for powering autos, houses and electronics. At the middle of the proton exchange membrane (PEM) fuel cell is the membrane electrode assembly (MEA). The MEA consists of a proton exchange membrane, catalyst layers, and gas diffusion layers (GDL). However, most of the researchers have already mentioned that PEMFC are not competitive enough to rechargeable lithium ion battery with respect to price because of the rare metal used such as platinum in it. Presence of platinum in PEM fuel cells is one of the reasons why fuel cells are excluded from commercialization.

Abstract The emergence of electric vehicle (EV) delivery trucks is resulting in health and environmental benefits, less noise, reduction of foreign energy dependency, and economic development opportunities. Green Loading Zones (GLZs) are dedicated curbside spaces for commercial delivery EVs meant to incentivize and accelerate market adoption. This study examined the impact and potential benefits of this strategy for New York City. Discussions with fleets revealed that while they are realizing operational savings and other benefits from the use of EVs, their incremental costs over diesel vehicles can take a very long time to recover, even with existing subsidy programs. Complementary incentives like GLZs can provide further justification for the investment in cleaner technology. Most fleets interviewed would place a high monetary value on guaranteed delivery locations and reduced parking violation expenses. Inclusion of GLZ electrical infrastructure to charge the EV battery could extend the range and operational capacity or permit the fleet to purchase vehicles with smaller battery packs, both of which would increase the cost effectiveness of this technology.
