The embodiments will be further described with reference to the accompanying drawings for the realization, the function and the advantages of the object of the present invention.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of assets management method.It is the asset management that one embodiment of the invention provides shown in referring to Fig.1
The flow diagram of method.This method can be executed by a device, which can be by software and or hardware realization.
In the present embodiment, assets management method includes:
Step S10, it makes an inventory current asset data, and according to the current asset data, generates assets procurement plan book.
In present pre-ferred embodiments, the current asset data include non-financial assets and fund procurement plan.
The non-financial assets include: (1) fixed assets: each department of national economy production, pipe are ensured on a timing point
Reason, service and resident living are normally carried out, and the Reusability in the defined time limit, and value meets as defined in financial rule
Material goods；(2) stock (inventory): production process is prepared to enter on a timing point and is played a role, and has exited and had produced
Journey but the physical product for not yet selling flow into the market places；(3) other material assets: including soil, forest, underground mineral money
Source, and culture, historical relic assets；(4) intangible asset: patent right, copyright, trade mark right, goodwill, etc..
Present pre-ferred embodiments according to early warning values such as the inventories of current asset data and preset every kind of assets,
And the fund procurement plan in the current year or current season, generate the assets procurement plan book.
By the assets procurement plan book, parent body will appreciate that Lower Establishment needs to buy or lease in certain year
Facilities plan substantially situation grasp in certain time period from Shen and by the plan of needs and corresponding fund planning of equipment
Please, examination & approval, contract signing, contract execution, payment situation and equipment purchasing or the details and relevant fund letter of lease
Breath.
When generating the assets procurement plan book, the formulation project plan, service program, procurement plan etc. first is appraised and decided
Type information, the performance requirement etc. of equipment are purchased, and each plan is aggregated to form assets procurement plan book.Then to buying
Task is examined step by step, and is bidded and purchased, and procurement contract is signed；And then buying task is executed, mainly by supplier
It completes, to the equipment purchased and sampling observation of examining goods of driving in the wrong direction, examines buying equipment whether to meet quantity, performance in procurement contract and want
It asks；Equipment purchase is finally completed, and transfers to assets card management module to carry out assets registration and uses.
Step S20, it is registered using assets of the presetting method to buying.
Present pre-ferred embodiments register the assets of buying using the method for assets card management.
The assets card management can be directed to user group's asset management feature, carry out classified and graded management to assets,
The assets are broadly divided into: fixed assets, intangible asset, are building assets etc. at current assets.Using assets card management
When method registers the assets of buying, the content of two aspects is related generally to: first is that assets encode；Second is that assets are put in storage.
Assets coding is numbered by row wealth portion, numbering be assets classes number+buy the time (two digits)+
Running number+department's coding etc..
For example, the code that assets classes are numbered in asset number are as follows:
GDZC-fixed assets LDZC-current assets
WXZC-intangible asset ZJZC-is building assets
After the assets purchased arrive at the destination, the examination of relevant departments is executed.After acceptance(check), asset number is carried out, so
After fill in " article proof of delivery " and handle storage formality.
Step S30, assets are carried out to the assets for being registered in library and uses management.
The assets realize the integrated management to asset equipment use information using management.To goods yard, shelf and warehouse with
Type, cost and the inventory balance of track equipment are registered.Recording equipment cost, including average purchase cost, it is newest buying at
This and user's declaration standard costs etc..The usage amount for counting any E & SP being stored in inventory, obtains newest at any time
Cost information and article inventory it is horizontal.System, which provides, periodically makes an inventory, and avoids occurring larger difference when once making an inventory in the end of the year.
First verification equipment storage bill, establish equipment card and Unit account of plant, association contract information etc.；Secondly according to lease/borrow/neck
With assets information, specify library facilities, the various status attributes that equipment is set, the bar code for generating new equipment, printing outbound list etc.；
Then the processing such as leased, borrow, receive, dispose according to outbound single pair assets；Finally to give back assets test registration,
And update current outbound state.
Step S40, it is realized using text similarity parser and Intelligentize query is carried out to assets, and according to inquiry content
In service life and purchasing price information, to assets carry out depreciation calculating.
Present pre-ferred embodiments may be implemented Intelligentize query inventory, with, repair and that scraps under state various sets
The increase of standby comprehensive information and equipment and reduction, borrow and give back, the contents such as the transfer of equipment and maintenance record are looked into
It askes, inquiring its condition can any combination.
Present pre-ferred embodiments realize the intelligentized search to query term by text similarity parser.Text phase
It is as follows like property parser process:
(1) search key is pre-processed: including segmenting, taking stop words, word2vec semantic extension,
The word2vec semantic extension stage.
(2) word is indicated in the form of vectors using the Open-Source Tools packet of deep learning: the main think of that vector form indicates
Want the vector operation being reduced to the processing of query text content in vector space, in this way converts similarity spatially to
Similarity semantically.It, can be similar between vector by calculating when inquiry content is represented as the vector of document space
Property measures the similitude between document.The wherein basic thought of vector space model:
Given inquiry content D=D (T1, T2 ... Ti ..., Tn), if Ti can not only repeat but also exist first in a document
Order afterwards, therefore analyzing can be more difficult.For above situation, the sequence of Ti is put aside, and require Ti inequality, at this time
T1, T2 ... Ti ..., Tn can be regarded as n dimension coordinate, per one-dimensional corresponding analog value Wi, therefore D (W1, W2 ..., Wi ..., Wn) is just
It is considered as a n-dimensional vector.
(3) Similarity measures.Cosine similarity calculation formula is widely used in the similarity calculation mistake between text data
Cheng Zhong.Its mathematical expression is as follows:
Wherein x, y are respectively the text term vector (being got by previous step calculating) for comparing similitude.Data are carried out to document
Pretreatment operation, data prediction use cosine similarity meter after converting vector for phrase using vector space model after the completion
The similarity between equations document is calculated, is matched so as to check out from predefined database with query term
Assets process flow.
(4) it according to inquiry content, is searched for from database the service life of the inquiry content, the related letter such as purchasing price
Breath.
(5) pretreatment operation is carried out to the data information that inquiry obtains: the initial data of extraction is generally required to carry out
Normalization and decorrelation handle the influence for reducing noise and linked character to final depreciation result.At data normalization
Reason is variation expression in form, is substantially to compare understanding.The normalization of data is to be allowed to data bi-directional scaling
Fall into a small specific sections.Since each characteristic measure unit in feature vector is different, in order to by index
It participates in evaluation to calculate, needs to carry out standardization processing to index, its numerical value is mapped to by some numerical intervals by functional transformation.
Currently used normalization processing method is z-score method for normalizing, and core concept is as follows:
X=(x- μ)/σ.
Wherein x is initial data (such as: service life, purchasing price etc.), and μ is the average value of original data set, σ
For initial data variance.In feature extraction and processing, it is involved in the problems, such as that high dimensional feature vector tends to fall into dimension disaster
The strong problem with feature association.With the increase of data set dimension, the sample size that algorithm study needs exponentially increases.
In some applications, it is very unfavorable for encountering such big data, and from big data focusing study need more memories and
Processing capacity.In addition, the sparsity of data can be higher and higher with the increase of dimension.It is explored in high-dimensional vector space same
Data set it is more difficult than being explored in same sparse data set.Principal component analysis is a kind of for exploring high dimensional data
The technology of structure.PCA is commonly used in the exploration and visualization of High Dimensional Data Set.It can be also used for data compression, data prediction
Deng.PCA can also be the low-dimensional variable that may have the higher-dimension variable synthesizing linear of correlation unrelated, referred to as principal component.New
Low-dimensional data rally retains the variable of initial data as far as possible.Data projection is realized dimensionality reduction to a lower-dimensional subspace by PCA.
For example, two-dimentional data set dimensionality reduction be exactly a projection is into a line, each sample of data set can be indicated with a value, no
Need two values.Two dimension can drop into 3-D data set, be exactly variable mappings into a plane.Under normal circumstances, higher-dimension phase
Closing data can be by mapping drop at low-dimensional non-relevant data.
(6) pretreated data are substituted into respectively in depreciation formula, the depreciation situation of the separate equations is calculated, after depreciation
The case where carry out minimax and handle, asset depreciation expense is calculated using voting mechanism.
Present pre-ferred embodiments use following the separate equations:
1. the time limit method of average is a kind of most simple and common method.This method is subtracted with the original cost of assets it is expected that net residual
Value acquires annual amortization charge divided by expected life.In each service life, valence of the assets transfer into product cost
Value is trend equal, that the accumulated value of depreciation linearly rises.Its calculation formula is as follows:
Yearly depreciation=(the estimated net salvage of 1-) ÷ is estimated service life (year) × 100%；
Moon amount of depreciation=fixed assets at cost × yearly depreciation ÷ 12.
2. Units-of-production method is to propose a kind of method of amount of depreciation according to real work meter.Its theoretical foundation is assets valence
The reduction of value is the function of assets behaviour in service.Folding is mentioned according to the behaviour in service of the business activities situation of enterprise or equipment to count
It is old.It is assumed that fixed assets cost represent a certain number of service units of purchase (can be mileage travelled number, hours worked or
Yield number), then press service unit's apportioning cost.This method compensates for composite life method only again using the time, does not consider to make
The characteristics of with intensity.Its calculation formula is as follows:
Working unit amount amount of depreciation=fixed assets at cost × (the estimated net salvage of 1-)/estimated amount of work；
A certain fixed assets moon amount of depreciation=this fixed assets this month workload × working unit amount amount of depreciation.
3. double decling balance method refers in the case where not considering that fixed assets expect net residual value, initial solid according to each issue
Determine the amount of money (i.e. net fixed assets) after assets original cost subtracts accumulated depreciation and double depreciation by straight-line method rate calculates fixed assets
Produce a kind of method of depreciation.Its calculation formula is as follows:
Yearly depreciation=2 ÷ are estimated service life (year) × 100%；
Moon amount of depreciation=net fixed assets × yearly depreciation ÷ 12.
4. year aggregative method is the original cost of fixed assets to be subtracted to the remaining sum of estimated net residual value multiplied by a fixed assets still
Serviceable bife is molecule, with estimated service life, the sum of number calculates annual folding for the score of denominator to successively decrease year by year year by year
Old volume.Its calculation formula is as follows:
Yearly depreciation=still service life/estimated service life year sums up × 100%；
Month amount of depreciation=(the estimated net residual value of fixed assets at cost -) × yearly depreciation ÷ 12.
The calculation formula of minimax processing of the present invention is as follows:
Wherein, fiIt is the amortization charge that i-th of depreciation method is calculated, max { f for depreciationiAnd min { fiIt is depreciation
The maximum value and minimum value of expense set.
The advantages of present pre-ferred embodiments, is as follows:
Semantic analysis can be carried out automatically according to input content, the assets to match with input content are searched from database
Data realize the automation inquiry of asset data；Intelligentized asset depreciation can be carried out to input assets, utilize a variety of assets
The depreciation method carries out Statistic analysis after carrying out depreciation to input assets, guarantees the accuracy of asset depreciation.

Type, cost and the inventory balance of track equipment are registered.Recording equipment cost, including average purchase cost, it is newest buying at
This and user's declaration standard costs etc..The usage amount for counting any E & SP being stored in inventory, obtains newest at any time
Cost information and article inventory it is horizontal.System, which provides, periodically makes an inventory, and avoids occurring larger difference when once making an inventory in the end of the year.
First verification equipment storage bill, establish equipment card and Unit account of plant, association contract information etc.；Secondly according to lease/borrow/neck
With assets information, specify library facilities, the various status attributes that equipment is set, the bar code for generating new equipment, printing outbound list etc.；
Then the processing such as leased, borrow, receive, dispose according to outbound single pair assets；Finally to give back assets test registration,
And update current outbound state.
Intelligentize query is carried out to assets Step 4: realizing using text similarity parser, and according to inquiry content
In service life and purchasing price information, to assets carry out depreciation calculating.
Present pre-ferred embodiments may be implemented Intelligentize query inventory, with, repair and that scraps under state various sets
The increase of standby comprehensive information and equipment and reduction, borrow and give back, the contents such as the transfer of equipment and maintenance record are looked into
It askes, inquiring its condition can any combination.
Present pre-ferred embodiments realize the intelligentized search to query term by text similarity parser.Text phase
It is as follows like property parser process:
(1) search key is pre-processed: including segmenting, taking stop words, word2vec semantic extension,
The word2vec semantic extension stage.
(2) word is indicated in the form of vectors using the Open-Source Tools packet of deep learning: the main think of that vector form indicates
Want the vector operation being reduced to the processing of query text content in vector space, in this way converts similarity spatially to
Similarity semantically.It, can be similar between vector by calculating when inquiry content is represented as the vector of document space
Property measures the similitude between document.The wherein basic thought of vector space model:
Given inquiry content D=D (T1, T2 ... Ti ..., Tn), if Ti can not only repeat but also exist first in a document
Order afterwards, therefore analyzing can be more difficult.For above situation, the sequence of Ti is put aside, and require Ti inequality, at this time
T1, T2 ... Ti ..., Tn can be regarded as n dimension coordinate, per one-dimensional corresponding analog value Wi, therefore D (W1, W2 ..., Wi ..., Wn) is just
It is considered as a n-dimensional vector.
(3) Similarity measures.Cosine similarity calculation formula is widely used in the similarity calculation mistake between text data
Cheng Zhong.Its mathematical expression is as follows:
Wherein x, y are respectively the text term vector (being got by previous step calculating) for comparing similitude.Data are carried out to document
Pretreatment operation, data prediction use cosine similarity meter after converting vector for phrase using vector space model after the completion
The similarity between equations document is calculated, is matched so as to check out from predefined database with query term
Assets process flow.
(4) it according to inquiry content, is searched for from database the service life of the inquiry content, the related letter such as purchasing price
Breath.
(5) pretreatment operation is carried out to the data information that inquiry obtains: the initial data of extraction is generally required to carry out
Normalization and decorrelation handle the influence for reducing noise and linked character to final depreciation result.At data normalization
Reason is variation expression in form, is substantially to compare understanding.The normalization of data is to be allowed to data bi-directional scaling
Fall into a small specific sections.Since each characteristic measure unit in feature vector is different, in order to by index
It participates in evaluation to calculate, needs to carry out standardization processing to index, its numerical value is mapped to by some numerical intervals by functional transformation.
Currently used normalization processing method is z-score method for normalizing, and core concept is as follows:
X=(x- μ)/σ.
Wherein x is initial data (such as: service life, purchasing price etc.), and μ is the average value of original data set, σ
For initial data variance.In feature extraction and processing, it is involved in the problems, such as that high dimensional feature vector tends to fall into dimension disaster
The strong problem with feature association.With the increase of data set dimension, the sample size that algorithm study needs exponentially increases.
In some applications, it is very unfavorable for encountering such big data, and from big data focusing study need more memories and
Processing capacity.In addition, the sparsity of data can be higher and higher with the increase of dimension.It is explored in high-dimensional vector space same
Data set it is more difficult than being explored in same sparse data set.Principal component analysis is a kind of for exploring high dimensional data
The technology of structure.PCA is commonly used in the exploration and visualization of High Dimensional Data Set.It can be also used for data compression, data prediction
Deng.PCA can also be the low-dimensional variable that may have the higher-dimension variable synthesizing linear of correlation unrelated, referred to as principal component.New
Low-dimensional data rally retains the variable of initial data as far as possible.Data projection is realized dimensionality reduction to a lower-dimensional subspace by PCA.
For example, two-dimentional data set dimensionality reduction be exactly a projection is into a line, each sample of data set can be indicated with a value, no
Need two values.Two dimension can drop into 3-D data set, be exactly variable mappings into a plane.Under normal circumstances, higher-dimension phase
Closing data can be by mapping drop at low-dimensional non-relevant data.
(6) pretreated data are substituted into respectively in depreciation formula, the depreciation situation of the separate equations is calculated, after depreciation
The case where carry out minimax and handle, asset depreciation expense is calculated using voting mechanism.
Present pre-ferred embodiments use following the separate equations:
1. the time limit method of average is a kind of most simple and common method.This method is subtracted with the original cost of assets it is expected that net residual
Value acquires annual amortization charge divided by expected life.In each service life, valence of the assets transfer into product cost
Value is trend equal, that the accumulated value of depreciation linearly rises.Its calculation formula is as follows:
Yearly depreciation=(the estimated net salvage of 1-) ÷ is estimated service life (year) × 100%；
Moon amount of depreciation=fixed assets at cost × yearly depreciation ÷ 12.
2. Units-of-production method is to propose a kind of method of amount of depreciation according to real work meter.Its theoretical foundation is assets valence
The reduction of value is the function of assets behaviour in service.Folding is mentioned according to the behaviour in service of the business activities situation of enterprise or equipment to count
It is old.It is assumed that fixed assets cost represent a certain number of service units of purchase (can be mileage travelled number, hours worked or
Yield number), then press service unit's apportioning cost.This method compensates for composite life method only again using the time, does not consider to make
The characteristics of with intensity.Its calculation formula is as follows:
Working unit amount amount of depreciation=fixed assets at cost × (the estimated net salvage of 1-)/estimated amount of work；
A certain fixed assets moon amount of depreciation=this fixed assets this month workload × working unit amount amount of depreciation.
3. double decling balance method refers in the case where not considering that fixed assets expect net residual value, initial solid according to each issue
Determine the amount of money (i.e. net fixed assets) after assets original cost subtracts accumulated depreciation and double depreciation by straight-line method rate calculates fixed assets
Produce a kind of method of depreciation.Its calculation formula is as follows:
Yearly depreciation=2 ÷ are estimated service life (year) × 100%；
Moon amount of depreciation=net fixed assets × yearly depreciation ÷ 12.
4. year aggregative method is the original cost of fixed assets to be subtracted to the remaining sum of estimated net residual value multiplied by a fixed assets still
Serviceable bife is molecule, with estimated service life, the sum of number calculates annual folding for the score of denominator to successively decrease year by year year by year
Old volume.Its calculation formula is as follows:
Yearly depreciation=still service life/estimated service life year sums up × 100%；
Month amount of depreciation=(the estimated net residual value of fixed assets at cost -) × yearly depreciation ÷ 12.
The calculation formula of minimax processing of the present invention is as follows:
Wherein, fiIt is the amortization charge that i-th of depreciation method is calculated, max { f for depreciationiAnd min { fiIt is depreciation
The maximum value and minimum value of expense set.
