calculate the economic indicators involved in LEA is given. In ensuring
the premise of reliability and safety, the model of economic analysis is
proposed to the purpose of optimal cost. Finally, based on the model of
economic analysis, building nuclear power plant equipment for life cycle
management support system has been studied and the corresponding
design and instances of system are given.

Abstract―In recent years, with the rapid development of network and
extensive adoption of J2EE platform, multi-layer Web structure based
on B/S grows up gradually. Aiming at the intelligent and standardized
management of power plant, this paper gives a detailed introduction of
the structure and function of the identification system for power plants,
as well as designing a database with great flexibility and extensibility
and a system based on J2EE design. This system has improved
the encoding specification, correctness and efficiency greatly. That is
to say, the system, having been put into practice in a power plant in
Guangxi, saves time and labor to a great extent.

Abstract―For least squares support vector machine (LS-SVM) classifier
to the loss of sparseness and generalization, a pruning modeling
method is proposed based on Quadratic Renyi entropy. The kernel principal
component is adopted for data pre-processing, and the training set
is divided randomly. Then the concept of quadratic Renyi entropy is introduced
as the basis of training and pruning in LS-SVM classifier. UCI
typical datasets of classification are used for testing the performance of
this new model. Experimental results show that the new algorithm takes
full account the location of the Lagrange multiplier, thus the sparseness
and generalization ability of the classifier can be improved.

Based on real-value vague sets risk preference score function, this
paper presents an approach for determining scoring value of interval
vague and applies it to multi-criteria decision making problems. The
approach completely embodies risk preference of decision maker as
well as the effect of various uncertain information to decision making.
Finally, an example is given to illustrate the effectiveness of the approach.

To further enhance emergency management skills of an organisation’s
emergency response personnel, emergency response training,especially
3D emergency drill, is currently becoming more and more
important in the petrochemical sector. So, a novel 3D emergency drills
system is designed and developed based on ACP approach, which can
be used for mocking emergency response plan drills and evaluating the
plan. A case study reveals that the performance of the system is good
and the system can meet the needs of emergency response training
and optimizing emergency response plan in petrochemical plants.

This paper presents a mission control approach and an on-board fault
recovery to enable an autonomous underwater vehicle (AUV) to carry
out the oceanographic survey autonomously. The challenges of AUV’
s operability in clutter environment have led the researchers to develop
intelligent control architectures composed of distributed, independent
and asynchronous behaviors, so the multi-agent system is applied.
A fault recovery architecture is designed to call the decision algorithm
and supervise the implementation of the autonomous mission based on
petri net formalism, which can respond to the changes in the environment
and internal issues. The feasibility and the algorithm effectiveness
of the architecture and mission control algorithm are checked by lake
experiment in nominal and degraded situations.

Descending rolling horizon procedure for equipment replacement problem,

To handle the computational complexity of large-scale optimization
problem, a special rolling horizon decomposition procedure is developed
to address equipment replacement problems with long decisionhorizons
and multiple alternatives in this paper. The global objective
is to minimize the total equipment replacement expense. The
rolling horizon procedure decomposes the whole decision-horizon into
serial rolling sub-decision-horizons where equipment replacement
sub-problems are established based on local objectives involving partial
global objective. The rolling horizon procedure can easily handle
the computational complexity of a large-scale equipment replacement
problem. However, the rolling segmentation and merely local optimization
are not able to necessarily lead to the global optimal solution because
local objectives are not completely consistent with the global one.
A terminal penalty is added into the local objective function of each subproblem
to lessen the disadvantageous impact of horizon decomposition.
The terminal penalty is the maximum evaluation of replacement
expense increment for the latter sub-decision-horizons due to merely
considering local optimization in the current sub-problem without any
consideration of the global objective. The theoretical analysis proves
that the rolling replacement procedure with terminal penalty can make
the global objective function values descending as serial sub-problems
are solved and their partial solutions are merged into the global solution
step by step. An extensive experiment was conducted to test the
effectiveness of descending rolling replacement procedure. The computational
results also demonstrate that this procedure is better than
traditional rolling horizon procedure for equipment replacement problem
while only moderate computational efforts are needed.
