Influence of geometric variables on spur gear volume
International Journal for Simulation and Multidisciplinary Design Optimization, 2020 Gear system optimization is currently topical amongst researchers. To this end, problem formulation is key and therefore knowledge of parameter influence and variation behaviour is indispensable.

Optimal experimental design for optimal process design: A trilevel optimization formulation
AIChE Journal, 2019 AbstractTypical optimal experimental design (OED) methods aim at minimizing the covariance matrix of the estimated parameters regardless of the intended application of the model that is being estimated. This can unnecessarily increase the experimental costs.

Discrete Mathematics, 1984 The tools in search of A-optimal designs are listed and the authors derive A-optimal chemical balance weighing designs (that is, \(N\times n\) matrices with elements 1, -1 and 0) for \(N\geq 7\), \(n\leq 6\).

Agriculture, 2022 In disturbance-assisted seed filling vacuum seed-metering devices, the suction hole causes difficulty in quickly and stably sucking seeds when used for high-speed seeding and the large working negative pressure demand is used. To address this difficulty,

Proceedings of the 22nd ACM Conference on Economics and Computation, 2020 We study the optimal method for rationing scarce resources through a queue system. The designer controls agents' entry into a queue and their exit, their service priority -- or queueing discipline -- as well as their information about queue priorities, while providing them with the incentive to join the queue and, importantly, to stay in the queue ...

SSRN Electronic Journal, 2010 This paper introduces three methodological advances to study the optimal design of static and dynamic markets. First, we apply a mechanism design approach to characterize all incentive-compatible market equilibria. Second, we conduct a normative analysis, i.e. we evaluate alternative competition and innovation policies from a welfare perspective. Third,

Design optimization of a three-stage transmission using advanced optimization techniques
International Journal for Simulation and Multidisciplinary Design Optimization, 2019 Gear transmission systems are very important machine elements and their failure can lead to losses or damage of other mechanical components that comprise a machine or device. Since gears are applied in numerous mechanical devices, there is need to design
