The intelligent human/computer interface communicated by PORT COM with service end data statistics module；
With the index model storehouse of the analysis model evaluated including multiple multidimensional major network repair schedules.
2. major network according to claim 1 overhauls multi-restriction Multi-Objective assessment experts system, it is characterised in that also include using
To be affected according to electric network fault rate, facility reliability and power failure national economy, in the net repair schedule overall merit module
Find the reasoning by cases module of immediate ripe case and control parameter is constrained according to the immediate ripe case,
Searching reaches evaluation module when certain class overhauls the check man of reasonable man-hour parameter.
3. major network according to claim 2 overhauls multi-restriction Multi-Objective assessment experts system, it is characterised in that the case
Reasoning module includes approximate case query unit and optimal solution case storage unit, and the approximate case query unit is to basis
Electric network fault rate value up to standard, maintenance and failure inverse ratio correlation coefficient and power failure national economy affect data, in the index model
Maintenance model in storehouse finds immediate ripe case, and the optimal solution case storage unit is to preserve with maximum failure rate
Under limit, the new case that obtains after economy and reliability are adjusted and using the new case as maintenance model.
4. the optimization method of multi-restriction Multi-Objective assessment experts system is overhauled based on the major network described in claim 3, and its feature exists
In, including：
Step 1：Data integration module obtains power transformating and supplying facility account data, power transformating and supplying facility event data, power transmission and transformation loop board
Account data, power transmission and transformation loop event data and repair schedule task derived data；
Step 2：All data is activations that data integration module in step 1 is obtained are to service end data statistics module, service end
Data statistics module is processed to data, then the parameter of renewal is sent to security assessment module, economic evaluation mould
Fast and reliability assessment module；
Step 3：Parameter initialization, by being contrasted with historical data optimum working condition, if approximate history, is then configured
Parameter is transmitted to maintenance scheduling for power systems PLAN Overall evaluation module, and stores historical data, terminates maintenance scheduling evaluation, if nothing
Approximate history, then inquired about to index model storehouse and reasoning by reasoning by cases module, finds immediate ripe case, and
The parameter for overhauling reasonable man-hour is searched out during by check man, configuration parameter is exported；
Step 4：After output configuration parameter, configuration parameter is transmitted to maintenance scheduling for power systems overall merit module, by input results,
The precomputation result of all kinds of control type indexs is analyzed, optimal solution is stored, terminates maintenance scheduling evaluation.
5. major network according to claim 4 overhauls the optimization method of multi-restriction Multi-Objective assessment experts system, and its feature exists
In in step 2, the safety evaluation carries out reduced value-at-risk by assessing repair schedule, embodies this maintenance meter
Draw improved safety, risk value calculating method：Value-at-risk（D）=probability index（P）× frequency index（F）× the order of severity
（S）；The economic evaluation is concretely comprised the following steps：It is first depending on 3 years consumption ratios of certain type of work history and calculates such work
Economic index value in meansigma methodss（α）And standard deviation（β）If the economic index value of certain plan exists（α±β）It is interior, then write from memory
Recognize judgement qualified；If the economic index value of certain plan exists（α±2β）Interior, then identifying automatically the plan needs subdivision to enumerate
It is bright；
During the reliability assessment, overall control is carried out with annual index, that is, require to consider early stage service work situation, current maintenance
Projected conditions and later stage projected conditions to be scheduled, reliability and electric load all have season undulatory property, therefore reliability evaluation
Using the undulatory property of moving average as the dynamic fundamentals of management.
