Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The technical scheme of the invention is further explained in detail by combining the drawings as follows:
the invention provides the following services for community users with close geographic positions: the system comprises a community group buying module, a product trial eating use module, a vegetable buying module, a nearby characteristic commodity buying module, a child picking-up module, a neighbor looking-up and old people looking for, a neighbor looking-up and flower and pet looking for, a neighbor looking-up and water and electricity looking for, a community windward vehicle, a parking space sharing module, a property notification pushing module, an owner chatting module and the like, wherein all functions are realized through the community group buying module, the owner issuing module, the trial eating trial use module and the like, and the system structure chart is shown in fig. 5. After the whole process is completed by three functions of community group buying, owner releasing and trial use, the buyer and the seller need to evaluate the product or service of the other party, and the system calculates respective credit value through a credit model to provide a basis for subsequent interaction.
The schematic diagram of the model of the group purchase B2CC in the multi-level community of the present invention is shown in fig. 1. In the B2CC mode, a merchant provides group buying service for community users close to the geographic position, group buying information published by a general block can be pushed in a plurality of sub-blocks according to the geographic position, and the group buying information is delivered uniformly after being intercepted. The mode relies on trust established by the relationship of geography, the purchase amount can be increased by utilizing the psychology of people, and meanwhile, the trust management system is used as the guarantee, so that the user can feel more relieved about various services. The B2CC mode optimizes the logistics mode of the current online shopping: on one hand, the multi-level group purchase mode of 'group purchase by different versions and unified delivery' can save energy, reduce emission and reduce logistics garbage; on the other hand, the sub-version group purchase initiated by the nearby merchants can achieve the purposes of facilitating residents, effectively utilizing peripheral resources and optimizing resource allocation.
The group buying function in the invention adopts a multilayer group buying mode, which is mainly embodied in a multilayer design mode of a master plate and a sub-plate and a sound credit evaluation management function, and fig. 2 shows the overall structure of the multilayer group buying design of the invention. The master plate block provides group purchase service for one area, the branch plate blocks serve community residents with the same delivery address, and the plate owners are plate managers regardless of the master plate block or the branch plate blocks. The general block is added by applying for a general commodity general distributor with higher credit, the general distributor needs to upload effective proofs before applying for adding the block, such as basic information of a legal person business license, an applicant identity card, a mobile phone number, an account opening bank and the like, if the general distributor needs to provide a health license, if an agent product needs an agent book, a product authorization book and the like, the general distributor can enter the block after the approval of the master. The community residents need to provide effective identification and determine the receiving address when joining the plate dividing blocks, one plate only has one receiving address, and the receiving address cannot be modified.
The design scheme of the multi-level group purchase function is shown in figure 3, and the whole process is as follows:
after the merchant releases the commodity in the general edition block, the information included in the released commodity is as follows: name of the goods, description of the goods, picture or video, expiration date, delivery area, minimum number of people in group, etc. After the review of the master layout owner of the master layout is passed, the sub-layout owners click a 'sharing' function to forward the order to the sub-layouts. The residents in the block community can follow the order and pay, and the general block merchant can check the condition of the block community. The community residents can cancel the order through the order cancellation function of the commodity before the merchant releases the goods, and the merchant does not schedule the delivery any more.
After the order cutting time is up, the system can automatically classify and gather orders in the sub-block to the server according to the block, and group purchase information of each sub-block is displayed in corresponding commodities of the total block, and the method comprises the following steps: group buying community, pickup location, buyer name, buyer phone number, buyer address, purchase quantity, etc.
The merchant arranges the goods according to the receiving address and the detailed order condition, clicks a 'delivery' button to start delivery, the order states of all community users are converted into a 'to-be-received' state, and the edition separation owner can check the order following condition of the edition and assist the post-delivery affairs. The general distributor delivers the goods to a specified position of a community, generally a group buying community gate, with the assistance of a version separating owner.
After the community user successfully takes the goods, clicking 'confirm delivery' in the system, and evaluating the dealer in the general block within a specified time. The edition separating main body checks the current order state, and if a user forgets to take goods exists, the edition separating main body has three modes to send a prompt: clicking a goods taking function, and sending a message to a user client through a system to inform a user of taking goods; selecting a 'short message sending' function in the system to send the information of the order and the goods taking place to the user; and selecting a 'call making' function in the system to call the group purchase user and inform the user of taking the goods.
If the commodity has quality problems, the buyer can click the function of applying for selling, the problem commodity is described in the following interface through pictures and characters, after the image-text information after applying for selling is published, the publisher and the seller receive detailed descriptions, the buyer and the seller need to coordinate and solve within 7 working days, and the publisher coordinates and promotes the problem to be solved.
After all users, merchants and the edition separating main evaluate each other, the system calculates the reputation value of each related party according to the corresponding algorithm in the trust management method, and finally the whole order process is finished.
The group purchase commodities can be released in the community section by a resident merchant in the community section (or section). The information included in the issued product is: commodity name, commodity description, picture or video, expiration date, delivery time, minimum group size, etc. After the edition-based main audit checks the commodities issued by the merchants, the community users follow the orders, cut the group after the order arrives at the deadline, and automatically collect the information of the follow group to the merchants. The merchant delivers goods according to the order information, the platemaker assists the merchant in delivering goods, promotes buyers to receive goods, assists in communicating and coordinating various problems in the buying and selling process, and the users confirm the goods receiving in the system after receiving the goods and mutually evaluate the goods. Finally, the split owner charges the merchant a flat charge on successful transactions.
Trial functional blocks. To gain the buyer's trust, the merchant may issue trial activity. The trial commodity is set on the front page of the plate. The merchant sets time and number for trial, community users in the version register trial after reaching specified time, and the system determines a trial user list according to time by adopting a first-come-first-obtain algorithm. After registration is finished, a merchant delivers goods to a community, a community user gives a score and concurrency table evaluation in commodity evaluation after trial use, the system recalculates the credit of the merchant by using a trust management algorithm according to the evaluation given by the user, and then the whole function is finished.
And the community users individually release the function blocks. Community users can publish personal appeal within a section, which can be divided into two cases.
In the first case, community users publish services as service providers. And the group owner carries out verification individual issuing according to the credit and other information given by the system, the verification can be returned if the verification is not passed, and the verification is displayed in the block after the verification is passed. And the residents in the residential area follow orders as required. And paying after the service is finished, evaluating the two parties, recalculating the credit of the merchant by the system according to the evaluation given by the user by adopting a trust management algorithm, and then finishing the whole order.
1. Using scenario one: when a personal user goes out for shopping, for example, buying vegetables, food nearby, other living goods and the like, generation purchase information can be issued in the cell block. Because the publisher is a neighbor and the system has detailed information such as the residence place of the publisher, other users trust the publisher relatively, on the other hand, the publisher tries to select commodities for other neighbors as much as possible in order to maintain the reputation of the publisher in the neighbor eyes, and after the transaction is finished, the two parties mutually evaluate in the system.
2. Using scenario two: the owner goes out to release the windward vehicle information, the user who has to be close to the destination can go on a journey together through the mode of carpooling, needs the carpooler to pay negotiation expense after the stroke is accomplished, and the neighbour goes on a journey factor of safety jointly, can also get through the neighbour relation.
3. Usage scenario three: with the release of the two-child policy, the problem that children get on and off school and pick up the children becomes a difficult problem of many families, but at present, the probability that children in the same community are in the same school is high, so that the App can be used by one parent to pick up and pick up several children together, and the parents who pick up and pick up the children do not have time to pay a certain fee.
In the second case, the community user issues an appeal as a service seeker, and the appeal is invisible to other users after the other users in the block take over the appeal. And after the help is sought, the two parties perform mutual evaluation, and the system calculates and displays respective credit values to finish the help seeking.
1. Using scenario one: the small trouble of the household electrical appliances, such as the fact that a ballast needs to be replaced when the lamp is broken, can release information on the plate and endow certain labor cost. Compared with the service of the home maintenance electric appliance, the service scene has the advantages that the home fee can be avoided among neighbors because the same cell and the close geographical position are in the same place.
2. Using scenario two: the resident is because going out, and the old man at home is looked after to nobody in the short time flowers and plants, pet, can issue the information in district's individual issuing module, and the district resident can follow the order according to self condition, and the publisher can be based on with single reputation value and evaluation selection neighbour, pay and mutual evaluation after accomplishing the service.
Besides, by means of trust built by the geopolitical relations of residents, residents can release information such as local caregivers for finding part and part of the functions nearby and sharing own parking spaces at fixed time points, and finally an intelligent community ecological chain is built through the mode to create a brand-new and green harmonious community.
No matter the total edition is group-purchased, the sub-edition is group-purchased, trial-eating and trial-use and owner individual release, each interaction basically comprises two roles of a buyer and a seller, after the buyer confirms receiving goods, the buyer and the seller mutually evaluate each other, and the credit values of the buyer and the seller are calculated according to the evaluation results. Reputation values consist of a recommended reputation consisting of a long-term reputation and a short-term reputation and direct reputation values, as shown in fig. 4.
The direct reputation calculation method is determined by evaluations given by two parties, and the evaluations are divided into five types: five stars, four stars, three stars, two stars, one star, the default is five stars. For ease of calculation, a mapping function for direct reputation (dirt _ rept) is introduced:
the medium-term and long-term reputation of the recommended reputation consists of four part factors of historical evaluation received two weeks ago, role of an evaluator, historical trading time and historical trading volume.
The evaluation received by the evaluated person two weeks ago is the historical recommended reputation of the evaluated person, and the calculation method of the evaluation is the same as the calculation method of the direct reputation and is recorded as the cust _ rept.
The role of the evaluator may be the buyer and the seller, if the role of the historical transaction (role) is the same as the role in the current interaction (curr _ role), the influence factor on this record is larger, otherwise the influence on the current evaluation needs to be reduced, so the role factor (role _ factor) of the evaluator is:
historical trading time also has a large impact on the current reputation value, and if trades occur long ago, there is a need to reduce the impact on the current trade. The present system defaults to this value as one year. curr _ time represents the current time, time represents the historical transaction time, and the time factor (time _ factor) is calculated by the following equation:
for the same commodity, the record of the larger historical transaction amount is more credible, so the large transaction is more likely to be a true transaction and should have a larger influence, so the volume factor (volume _ factor) function is as follows:
the whole recorded credit factor accp _ factor is:
accp_factor＝role_factor×time_factor×volume_factor
therefore, the long-term reputation value (long _ rept) is calculated by:
the medium-short term reputation of the recommended reputation is to analyze the short term behavior by using the real-body evaluation in the last two weeks. First, two variables need to be introduced: x is a radical of a fluorine atomi＝timei-(curr_time-14)，yi＝cust_repti；xiRepresenting a phaseFor time, yiIndicates user rating, presence (x)1，y1)，(x2，y2)，…，(xn，yn) And (4) sequencing.
And defines the constant:
also:
and:

Parameter(s)
Calculating to obtain;
then, the short-term reputation value is given by:
the recommended reputation is a combination of short-term reputation and long-term reputation:
rec_rept＝0.4×long_rept+0.6×short_rept；
finally, the final reputation values of the two parties after the current transaction are shown in the following formula, wherein the recommendation reputation accounts for 70%, and the direct reputation or the evaluation of the current user accounts for 30%:
rept＝0.7×rec_rept+0.3×dir_rept。
and a community chat module. The user who joins the plate can enter the community chat function through the navigation button at the bottom of the mobile App. The plate owner is an administrator of the chat module, the statement about the illegal publication can be forbidden, and the plate can be kicked out seriously. Any user can share interested group buying, individual publishing, trial and trial in the chat module in a picture-text link mode. The user can set a group message receiving mode, and the group message mode mainly comprises the following steps: reminding, receiving and not reminding, and not receiving. By default, the reminder, i.e., the receipt of any group message, causes the navigation bar icon to blink and prompt for the number of messages. And if the user receives no reminding, the user receives any group message and is identified by a small red icon in the navigation bar, and the user can open the chat function to view. The group messages are not accepted, the users do not receive any prompt information, and the messages which are not viewed are emptied after the message amount exceeds the maximum cache of each user.
And a community news module. The publisher may set up an administrator of the news module, typically a property worker or a person in charge of the proprietary committee. Property notifications, community activities, proprietary board activities, etc. may be published in the module. The publisher and administrator may set-up posts in the news module. The community news module can share the chat module in a picture and text link mode.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
