Fig. 1 is the schematic flow sheet for being used to dynamically adjust the method for product price of one embodiment of the invention.According to this The method of embodiment includes step S1, step S2 and step S3.

In step sl, when the present price end cycle of product, computer equipment is working as present value according to the product The cycle data in lattice cycle and a upper price cycle, obtained the mechanical periodicity information of the product.

Wherein, a product corresponds to multiple continuous price cycles.It should be noted that product of the present invention is not A specific products (such as mobile phone of model " X ", the film ticket of certain film) is limited to, the product can be price cycle Identical product set (such as film ticket of multi-section film), therefore, the scheme of the present embodiment are applicable not only to dynamic and adjust certain The price of individual specific products, and suitable for adjusting the price of identical multiple product price cycle simultaneously.

It should be noted that preferably, the quantity of the price cycle of product is probably predetermined, or restricted bar Part, or it is unconfined；Also, the Cycle Length of each price cycle of product may be fixed or variable, such as may be used The Cycle Length of follow-up price cycle is adjusted flexibly.Preferably, the stop condition of the price cycle of product can be pre-set (as produced Pin Xia cities etc.), or the price cycle of manual termination's product.

Wherein, the cycle data includes product caused any data within a price cycle, such as the valency of product Lattice data, sales data etc..

Wherein, the mechanical periodicity information includes any for indicating product in present price cycle and a upper price week The information of mechanical periodicity situation between phase, rate change information, the sales volume change information of such as product, wherein, the valency Lattice change information is used for the price behavior for indicating product, and the sale change information is used for the sales volume change for indicating product Situation.It should be noted that during a price cycle, product may be corresponding with multiple prices, the film of such as one film Ticket may have different prices in different movie theatre difference plays.Preferably, the mechanical periodicity information of product can indicate product Change in each dimension, wherein, dimension refers to the various factors for influenceing the price of product, as influenceed the price of film ticket Factor includes but is not limited to：Movie name, movie theatre, city, price etc..

As a step S1 example, for a film shown, each price cycle of its film ticket Cycle Length is one day, and at the end of one day (namely present price end cycle), computer equipment is existed by comparing film ticket The cycle data on the same day and in the cycle data of upper one day, obtains the mechanical periodicity information of film ticket, the mechanical periodicity information refers to Show the price reduction of film ticket 5%, and sales volume adds 10%.

In step s 2, computer equipment is according to the mechanical periodicity information and the dimensional information of the product, it is determined that The multiple price units corresponding with next price cycle of the product.

Wherein, the dimensional information includes any information related to the price dimension of product, more as corresponding to product Association between dimension values that individual dimension, each dimension are included, dimension values etc..For example, dimension includes corresponding to film ticket：Shadow Institute, city, price；Wherein, movie theatre, which includes " star is beautiful " and " middle shadow ", city, includes " Shanghai ", " Beijing ", " Chengdu ", " price " Dimension includes 30,40,50, and the dimension values included by " price " dimension are the initial price of film ticket herein, such as the part in Shanghai Play is initially priced at 30, and another part play is initially priced at 40, then when the dimension values of " city " dimension are " Shanghai ", The dimension values of " price " dimension include 30 and 40 accordingly.

Wherein, the price unit represents the granularity for being fixed a price, namely the base unit of adjustment product price.Its In, a price unit can correspond to one or more dimension values, when a unit of fixing a price corresponds to multiple dimension values, the plurality of dimension Angle value can correspond at least one dimension.For example, one of product price unit meets that " city=Shanghai " (namely Shanghai is all Film play), another price unit of product meets " city=Beijing, movie name=Warcraft ", and (namely " Warcraft " in Beijing All film plays), equal sign front end that is above-mentioned or subsequently occurring is dimension, and equal sign rear end is dimension values.

As a kind of preferred scheme, the step S2 further comprises step S21-1, step S21-2 and step S21-3.

In step S21-1, computer equipment constructs the dimension tree of the product according to the dimensional information of product.

The schematic diagrames that is directed to dimension tree that film ticket construct of the Fig. 2 by an example of the present invention.Wherein, film ticket includes Following dimension：Movie theatre, city, price；Wherein, movie theatre includes " star beautiful " and " middle shadow ", city including " Shanghai ", " Beijing ", " into All "；Price includes 30,40,50.It should be noted that Fig. 2 exemplarily only shows the partial periodicity data of product.

It should be noted that if the dimensional information of product does not change, the dimension tree of product be it is constant, therefore, After the dimension tree of first time construction product, the dimension tree can be stored, then make it that in follow-up price cycle step need not be repeated Rapid S21-1's operates to construct the dimension tree of product；(dimension of such as product however, if the dimensional information of product changes Angle value is removed), the dimension tree of product should be reconfigured, therefore, in step S21-1, if the dimension previously constructed be present Tree, then can first judge whether the dimensional information of product changes, if if changing according to after change dimensional information construct The dimension tree of product, if not changing, directly obtain the dimension tree previously constructed.

In step S21-2, computer equipment calculates each dimension in dimension tree according to the mechanical periodicity information of product The corresponding price standard entropy of value.

Wherein, the price standard entropy represents the consistent implementations of the mechanical periodicity distribution of dimension values.

Preferably for a dimension values of product, computer equipment is based on equation below, according to the dimension in dimension tree The mechanical periodicity information of all nodes under value, calculates the price standard entropy H corresponding to the dimension values：

H=-rPP*ln (rPP)-rPN*ln (rPN)-rNP*ln (rNP)-rNN*ln (rNN)

Wherein, rPP=| PP |/SUM, rPN=| PN |/SUM, rNP=| NP |/SUM, rNN=| NN |/SUM, SUM=| PP |+| PN |+| NP |+| NN |, ln represents the natural logrithm using e as the truth of a matter.Wherein, table 1 gives PP, PN, NP, NN definition：

Table 1

Wherein, Δ cyclical sales amount represents the cyclical sales amount change of each node under the dimension values, Δ cycle price Represent the cycle price change of each node under the dimension values, upward arrow represents nonnegative value (namely on the occasion of or 0), downwards Arrow represent negative value.Can be the node of nonnegative value according to corresponding Δ cyclical sales amount and Δ cycle price based on table 1 According to corresponding Δ cyclical sales amount it is nonnegative value and Δ cycle price is that the node of negative value calculates PP is calculated According to corresponding Δ cyclical sales amount it is negative value and Δ cycle price is that NP, root is calculated in the node of nonnegative value to PN NN is calculated according to the node that corresponding Δ cyclical sales amount and Δ cycle price are negative value.

It should be noted that above-mentioned formula is only for example, rather than limitation of the present invention, it will be appreciated by those skilled in the art that Other can be used in calculating the implementation of the price standard entropy of each node in dimension tree, should also be included in the scope of the present invention It is interior.

In step S21-3, computer equipment is according to the price standard entropys of each dimension values being calculated, and based on mark Quasi- entropy minimum principle, the dimension tree is divided into the multiple price units corresponding with next price cycle of product.

Wherein, the standard entropy minimum principle refers to draw to perform based on the minimum dimension values of corresponding price standard entropy Divide operation.

As an example, Fig. 3 is that dimension tree shown in Fig. 2 is divided into multiple units of fixing a price by an example of the present invention Schematic diagram, first, the price standard entropy of each dimension values in computer equipment dimension tree according to Fig. 2, determine dimension values " on Price standard entropy corresponding to sea " is minimum, then dimension tree is divided into the tree comprising " Shanghai " and do not included by computer equipment The tree in " Shanghai "；Then, for including the tree in " Shanghai ", computer equipment determines the price standard entropy of dimension values " 30 " in the tree Minimum, then computer equipment the tree comprising " Shanghai " is further divided into the tree comprising " 30 " and tree not comprising " 30 "；It is right In the tree not comprising " Shanghai ", computer equipment determines that the price standard entropy of dimension values " 30 " is minimum, then computer equipment will not Tree comprising " Shanghai " is further divided into the tree comprising " 30 " and the tree not comprising " 30 ".In Fig. 3, " MIN=X " represents dimension Value X price standard entropy is minimum, and " NON-X " represents not including X, and X is dimension values, do not include as " NON- Shanghai " represents " on Sea ".

Specifically, computer equipment is according to the price standard entropy of each node being calculated, and minimum based on standard entropy Principle, the dimension tree is divided into the implementation bag of the multiple price units corresponding with next price cycle of product Include but be not limited to：

1) computer equipment is according to the price standard entropy, and is based on standard entropy minimum principle, and the dimension tree is divided For the predetermined quantity price unit corresponding with next price cycle of the product.

For example, predetermined quantity is 4, computer equipment is based on standard entropy minimum principle according to the price standard entropy, first Dimension tree is divided into Tree1 and Tree2；Then, computer equipment is according to the price standard entropy, and it is minimum to be based on standard entropy Principle, Tree1 is divided into Tree11 and Tree12, and Tree2 is divided into Tree21 and Tree22, and by Tree11, Tree12, Tree21, Tree22 are as the 4 price units corresponding with next price cycle of product.

In another example predetermined quantity 3, computer equipment is based on standard entropy minimum principle according to the price standard entropy, Dimension tree is first divided into Tree1 and Tree2；Then, computer equipment is selected based on pre-defined rule (such as number of nodes is more) Determine Tree1, and be based on standard entropy minimum principle, Tree1 is divided into Tree11 and Tree12, and by Tree11, Tree12, Tree2 is as the 3 price units corresponding with next price cycle of product.

2) computer equipment is according to the price standard entropy and predetermined support, and is based on standard entropy minimum principle, will The dimension tree is divided into the multiple price units corresponding with next price cycle of the product.

Wherein, the predetermined supports conditions supported to represent predetermined price unit and need to met, such as predetermined support indicate Sales volume is more than 1000 etc..

For example, price standard entropy of the computer equipment according to each dimension values of product, and standard entropy minimum principle is based on, Dimension tree is divided into two trees for meeting predetermined support；The each tree obtained for division, computer equipment is according to product Each dimension values price standard entropy, and be based on standard entropy minimum principle, the tree be further divided into meet predetermined support Two trees of degree；The like, support that the tree for meeting predetermined support can not be obtained.

It should be noted that when that dimension tree can not be divided into the price unit for meeting predetermined support, can be by entirely Dimension tree is as a price unit.

It should be noted that the above-mentioned implementation 1 of the step S21-3) and 2) can be combined.For example, computer Equipment is based on standard entropy minimum principle according to the price standard entropys of each dimension values of product, and dimension tree is divided into satisfaction Two trees of predetermined support；For the obtained each tree of division, computer equipment is according to the prices of each dimension values of product Standard entropy, and standard entropy minimum principle is based on, two trees that the tree is further divided into meeting predetermined support；Class successively Push away, until the tree for meeting predetermined support can not be obtained, or, pass through the tree of division operation acquisition predetermined quantity.

As step S2 another preferred scheme, the step S2 comprises the following steps：Computer equipment is according to The dimensional information of mechanical periodicity information and product, the multiple dimension collections corresponding with product are obtained, wherein, a dimension collection At least one mechanical periodicity situation for closing included each object is same or similar；Then, computer equipment is according to Multiple dimension collections, it is determined that the multiple price units corresponding with next price cycle of product.

Wherein, the mechanical periodicity situation includes but is not limited to price behavior, sales volume situation of change etc., can be based on The mechanical periodicity information of product obtains the mechanical periodicity situation of each dimension or dimension values of product.

Wherein, the object that the dimension collection includes can be the dimension or dimension values of product.Preferably, sale can be based on Amount increase or decrease, the increasing degree of sales volume or reduce amplitude, the raising or reduction of price, the increase rate of price or drop Low amplitude etc. is same or similar to judge the mechanical periodicity situation of which dimension or dimension values.For example, dimension values " Shanghai " are right The sales volume increasing degree answered is 15%, and sales volume increasing degree corresponding to dimension values " Beijing " is 12%, then it is believed that dimension The mechanical periodicity situation for being worth " Shanghai " and " Beijing " is close.

Wherein, computer equipment can by the various ways such as statistical analysis, cluster come according to the mechanical periodicity information with And the dimensional information of product, obtain the multiple dimension collections corresponding with product.

Wherein, computer equipment can determine a price unit based on one or more dimension collections.For example, computer Equipment can directly using a dimension collection as one price unit, or, when based on determined by a dimension collection price When unit can not meet predetermined support, the dimension collection is combined to determine that meets a predetermined branch with other dimension collections The price unit for degree of holding.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than the limit to the present invention System, it should be appreciated by those skilled in the art that any according to the mechanical periodicity information and the dimensional information of product, it is determined that with production Next price cycles of product corresponding multiple price units implementation, should be included in the scope of the present invention.

In step s3, computer equipment is determined during next price cycle in the multiple price unit The price of each price unit.

Specifically, computer equipment can be determined the multiple during next price cycle using a variety of implementations The price of each price unit in price unit.

Alternatively, for each price unit in the multiple price unit, the price unit is calculated Marginal benefit；According to the marginal benefit, it is determined that during next price cycle in the multiple price unit The price of each price unit.The alternative will be described in detail in subsequent embodiment.

Alternatively, it is corresponding according to the price unit for each price unit, computer equipment Mechanical periodicity situation, to improve or reduce the price of the price unit.

For example, in step s 2, computer equipment according to the sales volume change information and dimensional information of product, obtain with Next price cycle of product corresponding two price units：U1, U2, wherein, U1 cyclical sales amount increase, U2 week Phase sales volume is reduced；In step s3, computer equipment improves U1 price, and drop according to U1 and U2 mechanical periodicity situation Low U2 price.

It should be noted that the price range for improving or reducing can be fixed or adjustable, such as different cycle Situation of change corresponds to different price ranges.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than the limit to the present invention System, it should be appreciated by those skilled in the art that any determine during next price cycle in the multiple price unit Each price unit price implementation, should be included in the scope of the present invention.

It should be noted that terminating whenever a price cycle of product, computer equipment just performs the side of the present embodiment Case determines the price of multiple price units corresponding to next price cycle and each price unit.Need furtherly Bright, computer equipment can dynamically be adjusted after second price cycle of product terminates based on the scheme of the present embodiment Whole product price；Preferably, price of the product during its first price cycle is usually predetermined, product its Price during two price cycles can be to predefine or based on determined by the cycle data of first price cycle.

In the prior art, the operator of product is typically based on manual analysis mode to realize the price of product or price adjustment, such as Each dimension of manual analysis product, current share data, price susceptibility (history ring is than data experience) etc., with based on analysis As a result price or price adjustment policymaking are made.However, the manual analysis mode needs to continue the specialized manpower of input, human cost is high, And mainly judged on the basis of historical statistical data based on experience, neither one standard reliably judges scheme so that Its analysis result can not accomplish very accurately, it is poor to further result in effect.

Also exist based on machine learning the scheme fixed a price to single product at present, present invention discover that the program needs A large amount of historical datas are collected, and require long period, all products can not be applied to.

According to the scheme of the present embodiment, adjustment product price can be automated, considerably reduces artificial input, is saved Human cost；, can be according to product in present price cycle and a upper price cycle when the present price end cycle of product Cycle data, and the dimensional information of product, to determine the multiple price lists corresponding with next price cycle of product Member, so as to further determine that the price of each price unit in the plurality of price unit so that the price of each price cycle Unit is dynamically determined, and by variable price unit, being capable of automatic identification influences the key element of price sensitivity, reality The differentiation price of existing product, lifts overall goals；By cycle iterations, it can be good at the strategy of reply market/competing product, and Any product can be applied to.

Fig. 4 is the schematic flow sheet for being used to dynamically adjust the method for product price of another embodiment of the present invention.According to The method of the present embodiment includes step S1, step S2 and step S3, wherein, the step S3 further comprises step S31 and step Rapid S32.Wherein, the step S1 and step S2 are described in detail with reference to the embodiment shown in FIG. 1, will not be repeated here.

In step S31, for each price unit in multiple price units for determining in step s 2, computer is set The standby marginal benefit for calculating the price unit.

Wherein, computer equipment can calculate the marginal benefit of price unit based on below equation：

The marginal benefit of price unit=| Δ cyclical sales amount/Δ cycle price |

In step s 32, computer equipment is according to the marginal benefit being calculated, it is determined that during next price cycle The price of each price unit in the multiple price unit.

Specifically, computer equipment is according to the marginal benefit being calculated, it is determined that described during next price cycle The implementation of the price of each price unit in multiple price units includes but is not limited to：

1) computer equipment is according to the marginal benefit and preset limit information, it is determined that in next price cycle The price of each price unit in period the multiple price unit.

Wherein, the preset limit information includes any restricted information related to the sale of product set in advance, excellent Selection of land, the preset limit information include but is not limited to：Default budget information, default ROI (Return On Investment, Rate of return on investment) information.Wherein, the default budget information includes any limitation letter related to product budget (namely subsidy) Breath is such as the master budget of product input, is the budget of each input price cycle.Wherein, the default ROI information includes appointing What restricted information related to ROI, such as target ROI.

Preferably, computer equipment is ranked up according to the size of the marginal benefit to the multiple price unit, is obtained Must be fixed a price cell queue；Then, computer equipment is according to the preset limit information and predetermined subsidy rule, from the price The larger one end of marginal benefit obtains a price unit and increases subsidy with not putting back to successively in cell queue, and/or, from institute The other end for stating price unit obtains a price unit and reduces subsidy with not putting back to successively, so as to can determine that each price is single The price of member.

As an example, computer equipment is according to corresponding marginal benefit from big to small to identified multiple prices Unit is ranked up, and obtains cell queue of fixing a price as shown in Figure 5：Fix a price unit 1, price unit 2 ..., price unit n, Wherein, | △ draws a bill/△ subsidies | represent the marginal benefit of price unit.In step s 32, computer equipment performs following grasp Make：

If i) current ROI is more than target ROI, computer equipment does not obtain with not putting back to successively from the front end of price cell queue One price unit, and increase the subsidy of acquired price unit, until current ROI is less than target ROI, perform operation ii)； If cell queue of fixing a price terminates for sky, operation.Wherein, after the subsidy of one price unit of increase, (△ always flows current RO1= Water+unit flowing water)/(△ always subsidizes+unit subsidy), wherein, the total flowing water of △ is the change of the overall amount of drawing a bill, and unit flowing water is should The amount of drawing a bill of price unit, △ always subsidies are the change integrally subsidized, and unit subsidy is the subsidy of the price unit.

Ii) if current ROI is less than target ROI, computer equipment does not obtain with not putting back to successively from the rear end of price cell queue A price unit is taken, and reduces the subsidy of acquired price unit, until current ROI is more than target ROI, performs operation i)；If cell queue of fixing a price terminates for sky, operation.Wherein, after the subsidy of one price unit of reduction, (△ is total by current RO1= Flowing water-unit flowing water)/(△ always subsidizes-unit subsidy).

Then after operation terminates, for each price unit, computer equipment can be increased based on the price unit to add deduct Few subsidizes to determine the price of the price unit.

2) computer equipment does not obtain the absolute value highest of marginal benefit with not putting back to from the multiple price unit every time With minimum two prices units, and following operate is performed to this two price units：

The price of the minimum price unit of absolute value of marginal benefit corresponding in this two price units is reduced, and is carried The price of another price unit in high this two prices unit, wherein, the price numerical value reduced and institute's huff Numerical value is identical.

Preferably, reduced obtain two price units with not putting back to every time after or huff is different, such as the first time Reduce or huff is 10 yuan, second of reduction or huff are 5 yuan etc..

As an example, in step s 2, computer equipment determines corresponding with next price cycle of product Four price units：R1、R2、R3、R4.In step S31, the limit of aforementioned four price unit is calculated in computer equipment Income is respectively：T1, T2, T3, T4, and T1<T2<T3<T4.In step s 32, computer equipment is first from this four price units Obtain T1 and T4 (T1 marginal benefit is minimum, T4 marginal benefit highest) with not putting back to, and by T1 5 yuan of price reduction, will T4 price improves 5 yuan；Then, computer equipment takes remaining T2 and T3, and by T2 4 yuan of price reduction, by T3 price Improve 4 yuan.

It should be noted that in this implementation, if current only surplus price unit, can not change the price unit Price, or improve or reduce the price of the price unit based on pre-defined rule.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than the limit to the present invention System, it should be appreciated by those skilled in the art that it is any according to the marginal benefit, it is determined that the institute during next price cycle The implementation of the price of each price unit in multiple price units is stated, should be included in the scope of the present invention.

, can be according to the marginal benefit for each price unit being calculated, to determine according to the scheme of the present embodiment The price of each price unit during next price cycle of product；Further, it is possible to further combined with preset limit information, come It is determined that the price for unit of each fixing a price, to realize that target maximizes (such as flowing water maximum, return rate highest under conditions of restriction Deng).
