It was done inoptimization palace and with a capacity of CHP as a production resource with the aim to increasethe reliability capacity. Decrease the loss and provide the electrical and thermal energies ofindustrial city. The f...

This paper describes results from a demonstration study utilising an integrated approach (SAMREL) for reliability of electricity supply analysis. The SAMREL methodology is based on a power market simulator (EMPS), a power system simulator (PSSE) and the OPAL methodology for reliability and interruption cost assessment. The integrated methodology is used for short and long term planning, such as...

We developed a heuristic procedure to optimize WDM networks with reliability as objective function. Optimization experiments have been carried out on a case study network, exploring the trade-off between network cost and reliability.

An effective anti-jamming system is significant in improving the working reliability of hydraulic drilling rigs. An anti-jamming valve is a core component of an anti-jamming system. A backpropagation (BP) neural network model was established for an anti-jamming valve by analyzing the structure and wo...

We consider steady-state production processes that produce a product and have feasibility constraints and metrics of cost and throughput that are stochastic functions of process controls. We propose an efficient stochastic optimization algorithm for the problem of finding process controls that minimize the expectation of cost while satisfying deterministic feasibility constraints and stochastic...

1. Abstract In this paper a robust and efficient methodology is presented for treating large-scale reliability-based, structural optimization problems under seismic loads using the pushover analysis method. The optimization problem is solved with the Evolution Strategies method, while the reliability analysis is carried out with the Monte Carlo simulation method. In order to reduce the excessiv...

In condition based maintenance (CBM) optimization, the main optimization objectives include maximizing reliability and minimizing maintenance costs, which are often times conflicting to each other. In this work, we develop a physical programming based approach to deal with the multi-objective condition based maintenance optimization problem. Physical programming presents two major advantages: (...
