Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...
Sustainable product design is becoming an important component of the development of consumer products. Currently there are limited design resources to aid in the creation of environmentally sustainable products. The purpose of this research is to theorize a new method for integrating sustainable design knowledge into the early design phase...
Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil...
Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...
A number of computational tools now exist to aid in developing conceptual solutions based on a functional description of a design problem. A key limitation of these tools is the way results are organized for presentation to the user. In general, results are an undifferentiated mass of potential solutions. Analysis...
Post-Consumer Recycled (PCR) resin grades have been successfully incorporated into plastic ink supply cartridges, with 80% of cartridge products containing 45% to 70% recycled polyethylene terephthalate (rPET). With this tremendously successful experience, incorporation of recycled polypropylene (rPP) into Injection Stretch Blow Molding (ISBM) bottles has been attempted to increase sustainability...
The total manufacturing cost for a part is determined by its process plan, and the total cost includes both processing and material handling costs. This research examines the cost impact of assuming an arbitrary layout when evaluating alternative process plans for production in a new facility. A designed experiment was...
Silicon carbide (SiC) and aluminum nitride (AlN) exhibit a combination of thermal and mechanical properties that are relevant to applications in electronics, aerospace, defense and automotive industries. However, the successful translation of these properties into final applications lies in the net-shaping of these ceramics into fully dense microstructures. Increasing the...
The purpose of this study was to determine the effects
of providing behavioral objectives prior to instruction on
the achievement of students in a one-semester college
general chemistry course and to determine the effect of
providing behavioral objectives of selected chemistry
experiments in the acquisition of achievement associated
with laboratory...
Work occupies a considerable amount of time in most peoples’ lives and can be a source of great pleasure or a source of pain. To enhance peoples’ experience at work, we must first understand how to measure and improve the design of work. This research sought to do just that,...
