Description

Assets life cycle management appraisal procedure based on the multiobjectives decision ideal point method
?
Technical field
The present invention relates to a kind of assets life cycle management appraisal procedure based on the multiobjectives decision ideal point method, belong to power grid asset management assessment technical field.
Background technology
Fast development along with China's electrical network, when how the management of power grid asset is implemented in power network safety operation, how to improve the assets profitability, prolong the electrical network economy life-span, realize assets benefit maximization and minimization of cost, become the key issue that power grid enterprises need to solve.The operation link is many, working interface is complicated, the phenomenon of multihead management, has had a strong impact on the real-time control efficiency of operation of power networks and existing assets life cycle management management mode exists.And operation organizational form and state-of-art are incompatible, are unfavorable for the control of electrical network overall coordination and company's intensivization development.Thereby cause the efficiency of management low, overall life cycle cost is bigger than normal.
In view of this, general thought and goal task in conjunction with " five is large " System Construction, turn to direction with intensive, flattening, specialty, take unified information platform, unified management standard, unified supporting as guarantee, according to efficiency comes first, goal orientation, suit measures to local conditions, the principle of safety and stability, form management and concentrate novel power grid asset management operation mode efficient, that resource intensive is shared, business integration connects, General Promotion power network development ability and efficiency of operation.By the system comprehensive index system of formulation under " five is large " system, and use multiobjectives decision ideal point method model, management is assessed to the power grid asset life cycle management, for the power grid asset management is provided decision support.
Summary of the invention
The objective of the invention is: for the power grid asset management is provided decision support, guaranteeing the reliable while of power grid security, improve the service efficiency of power grid asset, reduce overall life cycle cost, realize power grid asset lean, overall process, comprehensive management, the present invention discloses a kind of assets life cycle management appraisal procedure based on the multiobjectives decision ideal point method.
Technical scheme of the present invention is that assets life cycle management administrative evaluation index system under foundation " five is large " system is carried out pre-service to index again, uses at last the multiobjectives decision ideal point method to obtain evaluation result.
The inventive method may further comprise the steps:
1, make up one with huge construction program, build greatly, large operation, general overhaul, large marketing be as the tree-shaped assessment indicator system of first class index.
Electrical network core business link under " five is large " system makes up tree-shaped Index system framework from safety, usefulness, three aspects of life cycle costing by analysis.In this Index system framework, huge construction program, large build, large operation, general overhaul, market as first class index greatly.According to the characteristics of " five is large " system, safety, usefulness, life cycle costing as the two-level index under every system.And the different technical characteristics of the every individual system of foundation, make up corresponding key index as three grades of indexs from safety, usefulness, three aspects of life cycle costing.
2, the unification, the nondimensionalization that carry out pointer type are processed.Comprising: the nondimensionalization of cost type index unification, interval type index unification, achievement data is processed, the setting of index weights.
In order to realize the comparable of dissimilar index values, need to carry out unification, the nondimensionalization of pointer type and process.
