Hybrid particle swarm optimization for multiobjective resource allocation

Resource allocation （RA） is the problem of allocating resources among various artifacts or business units to meet one or more expected goals, such a.s maximizing the profits, minimizing the costs, or achieving the best qualities.

System deployment optimization in architecture design

Optimization of architecture design has recently drawn research interest. System deployment optimization （SDO） refers to the process of optimizing systems that are being deployed to activi- ties. This paper first formulates a mathematical model to theorize and operationalize the SDO problem and then identifies optimal so- lutions to solve the SDO problem. In the solutions, the success rate of the combat task is maximized, whereas the execution time of the task and the cost of changes in the system structure are mini- mized. The presented optimized algorithm generates an optimal solution without the need to check the entire search space. A novel method is finally proposed based on the combination of heuristic method and genetic algorithm （HGA）, as well as the combination of heuristic method and particle swarm optimization （HPSO）. Experi- ment results show that the HPSO method generates solutions faster than particle swarm optimization （PSO） and genetic algo- rithm （GA） in terms of execution time and performs more efficiently than the heuristic method in terms of determining the best solution.

New product design strategies with subsidy policies

Industrial development can enrich people’s lives,but it also causes environmental pollution,which is an area of significant concern among governments,consumers,and companies.Governments formulate some environmental policies,which motivate industry by providing greater incentives for green product development.Consumers are classified into two groups - ordinary and green market segments - according to their environmental awareness and attitudes.In this regard,companies need to reconsider their primary product design strategies.By investigating the interactions among customers’ preferences,firms’ product strategies,and government subsidy policies,this paper presents a theoretical model for new product design strategies.After detailed theoretical analysis of such strategies,we found that to motivate firms to choose environmentally friendly product design strategies, governments should inaugurate effective subsidy policies.After simultaneously considering environmental issues and firms’ benefits,we designed a subsidy policy.With such a policy,firms can change their primary product design strategies and develop both green and ordinary products,thereby increasing the firms’ profits and improving the total environmental quality.

Resource allocation for multiuser STBC-BF MIMO-OFDM downlink with imperfect channel information

To improve the performance of a multiuser MIMO-OFDM system with imperfect channel status information, a downlink adaptive resource allocation algorithm which combines space-time block coding and beam forming (STBC-BF) is proposed. The algorithm allocates the subcarriers with a shared manner. A zero forcing processing with joint Rx-Tx is used to suppress the co-channel interference (CCI) and to construct uncorrelatedchannels for STBC. An adaptive power allocation for the STBC equivalent channels can increase signal to interference and noise ratio at the receiver. Simulation results show that under the condition of an imperfect CSI, the proposed algorithm improves the system performance and reduces the number of BS transmit antennas required.

Resource allocation for cooperative diversity systems based on quadrature modulation

To improve the error performance and the resource utilization of cooperative systems, the optimum resource allocation, i.e., power allocation and partner choice, for an adaptive decode-and-forward (DF) cooperative diversity system based on quadrature modulation is investigated. The closed-form expression of the bit error rate (BER) system performance is derived and an optimal power allocation (OPA) algorithm is proposed to optimize the power allocation between the local and relayed signals under the minimum BER criterion. Based on the OPA algorithm, a partner choice strategy is proposed to determine the partner locations specified by various cooperation gains. Simulation results show that the proposed resource optimization algorithms are superior to the unoptimized algorithms by significantly reducing the BER and improving the cooperative gain, which is useful to simplify the practical partner choice process.
