The suitability of turbine configurations to different wind resources has been traditionally restricted to considering turbines operating as standalone entities. In this paper, a framework is thus developed to investigate turbine suitability in terms of the minimum cost of energy offered when operating as a group of optimally-micro-sited turbines. The four major steps include: (i) characterizin...

The problem of minimum cost in-network fusion of measurements, collected from distributed sensors via multihop routing is considered. A designated fusion center collects all the sensor measurements and performs a statistical-inference test on the measurements, which are spatially correlated according to a Markov random field. Conditioned on the delivery of a sufficient statistic to the fusion c...

Villaseñor, Eric Ph.D., Purdue University, May 2015. Improving Capacity-Performance Tradeoffs in the Storage Tier. Major Professor: Mithuna Thottethodi. Data-set sizes are growing. New techniques are emerging to organize and analyze these data-sets. There is a key access pattern emerging with these new techniques, large sequential file accesses. The trend toward bigger files exists to help amor...

In this study, by integrating preventive maintenance (PM) into a two-dimensional warranty region, with customized PM (2D PM) is proposed from the manufacturer’s perspective to reduce cost. The cost of 2D derived. tradeoff between and minimal repair saving obtained choosing proper reliability threshold number PMs, advantage illustrated. Second, post-warranty period, bivariate (BPWM) policy consu...

Modular manufacturing is gaining popularity in a variety of industrial applications due to potential cost-savings as well process flexibility that can be achieved with the use small and standardized modules. In this work, framework for supply chain optimization proposed ensures production feasibility help historical data individual modules machine learning-based analysis. A problem formulated w...

We study the strategic design of a supply chain for new products. Planning a supply chain for a new product requires addressing both uncertainties in demand and cost and changes in market conditions over time. We develop a mathematical programming model for new products that includes both financial viability and robustness relative to uncertainty. An example based on a Fortune 200 company’s eff...

Network designing often involves two significant yet contradictive objectives: enhancing the whole network’s transmission efficiency while at the same time lowering the whole network’s designing cost. Deep study of the interplay between major aspects of network planning– network topology, routing algorithm and node’s transmission capability configuration–reveals that good tradeoff canbe achieve...

Cost-effective reconfiguration in ODBMSs is difficult to achieve due to the tradeoff between modularity and efficiency. Existing ODBMS designs offer limited reconfigurability because reconfigurable features are closely woven with the components to improve efficiency. This paper proposes the use of aspects entities used by Aspect-Oriented Programming to localise cross-cutting concerns to separat...
