Foundation pit engineering is composed of some inter-related and relatively independent sub-engineering which makes it possible to introduce the distributed parallel optimal method into foundation pit engineering design. Based on the genetic algorithm with intrinsic parallelism, a distributed three-level co-evolution model and its corresponding algorithm, which can realize collaborative optimal design...
Establishment of the optimal objective function is the first and a vital step for optimum design. The foundation pit engineering design is a procedure of multi-objective optimization and multi-objective decision. Some of these objectives can be quantitatively calculated, while others cannot. In order to make a comprehensive analysis of the effects of various factors on the optimum design of foundation...
Foundation pit engineering is a complex system with multi-tier and multi-parameter. Since the scheme design and detail structure design belong to two different tiers of its optimum design, the foundation pit engineering's optimum design needs to combine these two tiers for co-optimization. Thus, this paper offered mathematical model for optimum design of foundation pit engineering's scheme, detail,...
In this paper, the optimization method of pump configuration is summarized for backward and bi-directionally pumped Raman amplifiers. Moreover, the power distribution of pumps, 100-channel optical signals, ASE and DRBS is simulated and demonstrated in detail, and DRBS noise power is far less than ASE noise power. For the bidirectional pumping scheme, less than 0.5 dB flatness of both gain and OSNR...
This paper presents a component-based model with a novel ranking method (CMR) for constrained evolutionary optimization. In general, many constraint-handling technique inevitably solve two important problems: (1) how to generate the feasible solutions, (2) how to direct the search to find the feasible optimal solution. For the first problem, this paper introduces a component-based model. The model...
In this paper, a floor plan design application for multilayer substrate is implemented. The simplified evaluation method for thermal, routing and area criterions are discussed and implemented. And then normalize the criterions before the substrate floor plan such that the settings for substrate floor plan are reasonable. And finally, the calculated routing length, area and ANSYS thermal simulation...
