(1) Marketplace type purchase (sales)
Transaction System Using Agents This transaction system is a system in which agent software working on the Internet performs negotiations and collects negotiations based on target values and negotiation rules determined in advance by owners (buyers or sellers). The agent software has an ability to convert an instruction from the owner into two, a target value and a negotiation rule, and can automatically negotiate based on the target value and the negotiation rule.

The roles of "exchange", "owner" and "agent" in the present system will be described below. An exchange located on the Internet provides one or more agents with a place to negotiate. The role of the exchange here is the following three. The first is to inform the other agent that one agent has entered the exchange. Second, the condition presented by one is transmitted to the other. Third, let one know that one has left the exchange. In addition, exchanges provide, in principle, only a place for trading and do not intervene in the negotiation of each agent, but in special cases, they may be set to intervene in the negotiation. . Also, entry and exit of each agent is not affected by the exchange's intention based on the agent's settings. In addition, the agents do not have to enter all at once, and can enter at a different time. This also follows the settings of the agent.

[0096] At an exchange, a plurality of negotiations may be conducted in parallel by an agent, but the exchange does not need to be connected in time. The exchange does not have the role of showing the negotiation title and the contents of the negotiation, such as "transaction about XX", or organizing the negotiation. Therefore, we do not know in principle what kind of negotiations the seller and the buyer have.

The owner starts the agent for each negotiation. The owner can set the negotiation target value and the negotiation rule for the agent in an interactive manner. Multiple agents can be activated for the same negotiation. The agents may perform the same or different functions.

The contents of the negotiation can not be known except by the two agents involved. Since the agent's presentation of the condition and the expression of satisfaction / dissatisfaction with the negotiation are shown only for the other individual agent, when the negotiation is completed, the two agents who are the parties to the negotiation leave, so other agents will not , You can only know the fact that you have been sent off. However, the agent can also notify the agent other than the party of the fact of the conclusion of the negotiation based on his / her own intention.

The agent can record the conditions given during the negotiation and the actual outcome of the negotiation in a record. As a result, at the time of the next business negotiation, the advantage obtained by this system that can assist in deriving the advantageous condition setting for the owner is as follows. First, by leaving the negotiation to the agent (software), Indirect costs such as labor costs involved in negotiations can be reduced. Secondly, it is possible to reduce the variation in the result of the negotiation by the person in charge of the negotiation. Third, operation outside normal working hours or 24 hours operation is possible. Fourth, an effective negotiation method can be derived by analyzing the records of the negotiation conditions and the results of the negotiations.

The field of application of the present system is preferably a field in which it is highly significant to use a negotiating agent and to have it performed by agent software. In particular, commercial transactions in which prices and transaction conditions are not uniform and are expected to fluctuate depending on the partner or situation, commercial transactions that require instantaneous judgment (real-time processing) from the presentation of conditions to conclusions, It may be applied to commerce where it is necessary to limit the exposure of profiles such as names and faces.

When the selling side or the buying side is singular, the operation of the exchange can be performed by one of the agents on the singular side. If there are multiple agents on the same side, leaving the exchange to one agent allows you to know the trading conditions of other agents via the exchange, and for the agent that operates the exchange, This is because it works advantageously. In the singular case, there is no worry. Further, when there are a plurality of exchanges on the Internet, it is possible to increase the number of negotiating agents by connecting to each other (virtual exchanges). FIG. 3 shows a marketplace type purchase (sales) in this embodiment. It is a flowchart which shows an example of operation | movement of the transaction system using an agent.

First, the owner A (seller or buyer) starts the agent software for A and calls the A negotiation agent (step S302).

Next, the owner A informs the negotiating agent A of the negotiating proxy request in an interactive manner (steps S304 to S304).
Step S306).

Next, the request is interpreted by the negotiation agent A, and a target value and a negotiation rule are set (step S3).
08). Here, the “target value” can be converted into a numerical value such as a target value in price, transaction amount, delivery date, quality (product / service), specification, payment condition, delivery condition, and the like. Priority among target values, order of offer, rules of numerical conversion field, negotiation start and negotiation duration, selection of negotiation counterparties, whether to modify the offer by yourself if you are not satisfied with the counter offer, and It is an agreement on how to report to the owner.

The target value and the negotiation rule interpreted by the negotiation agent A are presented to the owner A (step S310), and the setting information is confirmed by the owner A (step S31).
2). It is preferable that the expression used for confirmation is displayed on the terminal in an expression that can be easily understood by ordinary people. Creation of the setting information approval document and conclusion of the contract are also performed (steps S314 to S324). This proves that the transaction performed by the A negotiation agent is on behalf of the owner A.

Next, the A negotiation agent of the owner A sets an offer and registers participation in the exchange (step S32).
8). Here, “offer” is a target value set based on the negotiation rule (initial value). Negotiation rules are not shown at all to the opposite (counter) negotiation agent. The exchange has been registered in advance (step S33).
2) Announce the appearance of the other negotiating agent. Thereby, the A negotiation agent can know the existence of the B negotiation agent who is the negotiation partner.

Next, negotiation start by the negotiation agent is started, and an offer is announced (step S33).
2). This is shown only to the opposite B negotiating agent. The offer destination can be specified in advance in the negotiation rules because there is a concern that the competitor is participating in the opponent in a mask. Here, the B negotiation agent also has its own target value and negotiation rules set by the owner B, similarly to the A negotiation agent.

Next, the B negotiation agent receives the offer (step S334).

Next, search for a counter offer (offer of the negotiating agent on the other side) (step S342),
The contents are confirmed (step S344). The search range of the counter offer can be specified in advance in the negotiation rules because there is a concern that the competitor is participating in the opponent with a mask.

Next, a determination of satisfaction / dissatisfaction is made based on the "target value" and the "negotiation rule" (step S34).
4) Satisfaction / unsatisfaction is notified to the negotiating agent on the opposite side (step S346, step S354). If both are satisfied (negotiation completed), closing is performed (step S348, step S336, step S35).
0). If either is unsatisfactory, one or both reset the target value and resume negotiations (step S35).
8, Step S360, Step S336, Step S
338). Which one resets the target value is based on the negotiation rules determined by each party (the negotiation ends here if none of the target values is reset). Here, the resetting of the target value is automatically performed by the negotiation agent based on the negotiation rule. The offer from the other negotiating agent (counter offer) will also be referred to during this reset.

Next, the negotiating agent reports the result of the negotiation to the owner (step S352). After the negotiation result is not notified to any other agent, the negotiation is terminated and the negotiation agent automatically leaves the exchange in the following cases (steps S362 to S366). -When the negotiating agent's own negotiation period expires (time-out)-When the negotiation with all the opposite negotiating agents is completed-When the negotiation period of all the opposite negotiating agents ends ( Timeout) ・ If no modified offer is generated from either negotiation agent based on the negotiation rules

(2) Transaction System Using Purchasing (Sales) Coordinator In this transaction system, the coordinator arranges negotiations on behalf of a plurality of owners (sellers or buyers) on the same side or their agents. Can be. "Coordinator"
Can understand the demands of not only multiple owners, but also their delegates, and replace those (scattered) demands with goals and negotiation rules that satisfy the whole, leading the entire owner to agreement. According to the target value and the negotiation rule, it is possible to go to the negotiation field by itself or to request a negotiation agent (software) for negotiation.

Hereinafter, the roles of the coordinating place, the coordinator, and the manager of the coordinator in the present transaction system will be described.

[Coordination site] provided on the Internet
Coordinates the requirements of multiple (single) owners or their agents (agent software).
Here, the role of the adjustment field is the following four. First of all,
The function setting information of the coordinator is posted and transmitted to the coordinator (owner or negotiating agent). Second, the presence of the coordinator who has entered the coordination hall is communicated to the coordinator. Third, the fact that the coordinator has been activated is transmitted to other coordinators who have not entered the coordination hall. Fourth, the coordinator is notified of the fact that the coordinator who has left the coordination place has left.

Here, the "coordination place" provides only a place for coordinating transactions, and does not intervene in principle to the coordinator and the coordinator (owner or agent). In some cases, it can be programmed to intervene. The entry and exit of the coordinator and the coordinator are based on each intention or setting and are not affected by the intention of the coordination site in principle, but in special cases, the entry and exit of the coordinator are forced by the function of the coordination site be able to. The coordinator does not have to enter all at once. You can also enter at different times. In the case of a negotiating agent, follow the setting of the negotiating agent. Also, at the coordination hall, a plurality of coordination projects may be performed in parallel, but the coordination hall does not connect. The coordinator does not know at all what kind of coordination is being performed. For example, it does not have the role of indicating the adjustment title or the content of the adjustment such as “Adjustment for XX” or of organizing the adjustment.

The “coordinator” collects the requests of a plurality of coordinators and creates a unified target value and negotiation rules. The coordinator depends on the presence of the coordinator who first entered the coordination area,
It is automatically activated in the coordination area. The coordinator is interactive,
Understand the coordinator's requirements, compile target values and negotiation rules, and do so until a unified target value and negotiation rules are set that will satisfy all coordinators. The result of adjustment (or progress) is communicated to the adjusted person. In principle, the coordinator's existence and requirements are treated anonymously with other coordinators in the same coordination project. However,
By giving the coordinator a notice in advance, non-anonymous treatment (policy of disclosure) can be performed. The coordinator does not deal with the dissatisfaction of the coordinator that has arisen during the coordination process without explicit instructions. The coordinator
Do not chase or take measures not to leave the coordinator's exit from the coordination place that occurred during the coordination process. The coordinator performs the negotiations himself or requests another existing negotiation agent (software). The behavior at the time of negotiation execution may be the behavior of the above-mentioned “negotiation agent”. In carrying out the execution, it is possible to request a substitute by doing it by himself or by depositing a target value and negotiation rules with another existing negotiation agent (software).

The “coordinator manager” manages the coordinator's performance. The coordinator's settings (timing to enter the coordination hall, coordination rules, coordination theme areas, handover to the negotiation phase, etc.) can be determined. The adjustment method needs to be communicated to the person to be adjusted. In order to check the coordinator's actual performance, the coordinating process and results are recorded, so that problems and troubles in the coordinating process can be dealt with and the setting method can be improved.

The merits obtained by the present transaction system will be described below. Even in the case of using a negotiating agent (software), if only purchasing or selling alone is used, the labor for negotiating business negotiations can be simply reduced, and effects such as buying power and selling power cannot be expected. However, in this transaction system, the use of a "coordinator" has the effect of finding an unprecedented price range, a new supply destination, and a new demand destination, especially in the case of goods that benefit from scale. There is expected.

In the case where the coordinator on the purchasing side is used, demand is expected to be reduced to reduce the price and stabilize the quality (by mass production).

Further, when a coordinator on the sales side is used, the supply amount is collected to speed up sales negotiations,
It is expected that there will be more customers who demand stable large-volume supply, and the accuracy of production and inventory plans will be improved.

The fields to which the present invention is applied (basically, what kind of product field is suitable) include the following fields.・ Functionality is emphasized and the system of functions is clear (functional products). For example, PC peripherals, general-purpose semiconductor parts (memory, CPU), module products such as HD, automobiles Parts and building members. -Sales volume per type is large and prices vary depending on the quantity (mass-produced products). For example, general consumer goods such as PCs, home appliances, automobiles, foods, middle foods, furniture, furniture, etc. Equipment, etc.・ Stable supply at a low price ・ Stable quality (raw materials, raw materials), for example, various mineral resources such as oil and iron ore, food raw materials such as corn, electric power, gas, communication services, transportation Social infrastructure services such as services.・ Selling and buying will not take place unless there is a message that draws attention from both sellers and buyers. , Financial products in general.

If the number of coordinators is limited to one (one case) as an option, the coordinating field may be integrated with the coordinator. The reason that the coordinating place was originally independent of the coordinator (s) is that the provision of information to the coordinator (owner, negotiating agent) is distorted because a specific coordinator is linked to the coordinating place. There is danger.

FIG. 4 shows purchase (sales) in this embodiment.
It is a flowchart which shows an example of operation | movement of the transaction system using a coordinator.

First, as a preliminary procedure, the coordinator's manager executes the coordinator's function setting (step S4).
02 to step S406). That is, a function setting such as an entry timing to the adjustment place, an adjustment rule, a method of agreeing the adjustment rule, and whether or not to pass to the negotiation phase is performed. Here, the “entrance timing” is determined by, for example, how many coordinators (owners, negotiating agents) have entered. Various methods are conceivable for the adjustment rule, for example, "take an average value", "take a maximum value (minimum value)", "follow the opinion of the owner who handles the largest amount".
The adjustment rules are not determined uniformly, but can be determined for each of target values and negotiation rules described later. Some of the adjustment rules are not determined in advance, but are determined at the time after the adjustment is started. In addition, the “adjustment rule agreement method” is a method for determining what adjustment rule is to be adopted, and includes, for example, “take majority vote”, “adopt the default value determined by the coordinator”, and the like. It also includes "measures when no agreement is reached." Also, "Setting of delivery of negotiation phase"
That is, after the coordination, the coordinator sets whether to act as a negotiating agent or to request another negotiating agent to negotiate. These settings need to be communicated to the coordinator (owner or agent) entering the coordination hall.

Then, the coordinator (= owner of adjustment (seller or buyer) or negotiating agent (agent software)) registers participation in the coordination hall (step S41).
4 to Step S418). The registration history is transmitted to the coordinator via the coordination hall.

Next, the coordinator enters the coordination hall (steps S408 to S412). The timing to enter the coordination hall is as set by the coordinator's manager. The coordinator
Set the reconciliation rule to the coordinator (owner or negotiating agent)
And agree with. The coordinators (owners and negotiating agents) who should reach an agreement are limited to those who already exist at the coordination site (software). In other words, the opinion of the coordinator who entered the coordination room after the coordination of the coordination rules is not reflected.

Then, the adjustment is started, and the coordinator (owner or negotiating agent) informs the coordinator of the request for adjustment (steps S422 to S428). Requests from the owner are communicated according to a form presented by the coordinator. The request from the negotiating agent is transmitted to the coordinator in a predetermined electronic form.

Then, the request is interpreted by the coordinator,
The target value and the negotiation rule are adjusted according to the adjustment rule (steps S430 to S440). "Target value"
As an example, the value can be converted into a numerical value such as a target value in price, transaction amount, delivery date, quality (product / service), specification, payment condition, delivery condition, and the like. The “negotiation rules” are rules for performing actual transaction negotiations after adjustment. This includes arrangements of priorities and offers between target values, rules for numerical conversion fields, negotiation initiation and duration, selection of negotiation partners, and how to report to the coordinator. . The target values and the negotiation rules interpreted by the coordinator are adjusted according to the adjustment rules. The adjusted target value and negotiation rules are confirmed by the coordinator. The expressions used for confirmation are those that can be understood by ordinary people. A contract will also be signed. It is proved that the adjustment made by the coordinator is on behalf of the coordinator.

Then, the adjustment is completed at the following points, and the adjuster leaves the adjustment place (steps S442 to S450). -When the adjustment is completed-When the coordinator's adjustment continuation period ends (time-out)-When the coordinator determines that the adjustment is not possible according to the preset adjustment rules and the adjustment rule agreement method , And report the result of the adjustment to the coordinator (owner or negotiating agent). After coordination, the coordinator acts as a bargaining agent or asks another bargaining agent to negotiate.

(3) Purchasing Agent Service with Purchasing Agent Right The purchasing agent service with purchasing agent right in the present transaction system is a method by which a purchasing agent (agent software) who has acquired a purchasing agent right from a purchaser for a fee pays the purchase agent service. It is a service that earns a reward through execution, but it is not a mere purchasing agency service, but a service that implements the purchasing agency service after obtaining the authority to execute the purchasing agency service for a fee. This is a system in which the purchaser acts as an incentive to lead the sales negotiation more advantageously to the purchaser in order to recover the fee for acquiring the right to purchase.

As an advantage of this service, the purchase agent can see the amount obtained by subtracting the paid commission right from the commission of the purchase agent service as the profit.
On the other hand, by adopting this service, the purchaser can also reduce part or all of the business such as sales negotiations, contracts, and payments related to the procurement of goods and services.

[0132] The number of contacts for the purchaser is limited to one for one purchase case. However, there may be more than one buyer at the counter. Also, there can be more than one purchase agent. Usually, a plurality of purchase agents raise one hand and make a proposal.

The field to which this service is applied is exemplified below.・ Purchase price and terms may be advantageous depending on the choice of suppliers and negotiation methods. ・ Situation where buyers have only limited choice of suppliers. ・ By collecting multiple buyers and buying in bulk. , Which can lower the purchase price ・ A case where the agent is likely to coordinate the agent's purchase with another buyer (one person in the figure, but does not appear in this figure)・ If you want to reduce the burden of indirect tasks such as purchasing suppliers, requesting quotes, order management, etc. that occurred on the buyer side. ・ Restrict the exposure of profiles such as the name and face of the buyer. Case of Necessary Transaction FIG. 5 is a flowchart showing an example of the operation of the transaction system that executes the purchasing agency service with the purchasing agency right in the present embodiment. It is a diagram.

First, candidates for a purchase agent are registered (steps S502 to S506). The buyer will indicate to the buyer that he is a potential buyer,
Apply for purchase agent registration to the purchaser.

Then, the purchaser presents the purchase requirement and provides information to the purchase agent candidate (step S50).
8). The buyer will be able to respond to the registered purchase agent candidate
Provide purchase requirements. Please note that based on the buyer ’s will,
Reference information such as a past trading history may be provided.

Next, a purchase agent proposal is made to the purchaser by the purchase agent candidate (step S510 to step S510).
512). The proposal is described so that the buyer can understand it.

Items included in the proposal contents include, for example, purchase item, purchaser, purchase condition target (specification / quality, delivery date, payment condition, etc.), purchase price target, purchase agent right fee,
Remuneration amount for the procurement agency service (an example of how to determine the amount of remuneration may be a concept based on a success fee in addition to a fixed amount fee. As an example of a concept of a success fee, the actual purchase amount is the purchase price at the time of proposal. The success fee may be determined depending on how much less than the expected amount is.), A method of reporting the purchase result, setting of a proxy right fee, and the like. The purchase commission is usually positive, but may be negative. The right to purchase the agent may be paid in points.

[0138] The purchaser determines the purchase agent candidate with the best proposal, and requests the purchase agent service (steps S514 to S528). The superiority of the proposal is left to the buyer's judgment. At the same time as the request, the purchaser issues a purchasing agency right, and the purchasing agency purchases this right for a fee (purchase agency right fee).

Next, the selected purchasing agent performs a purchasing agent service (step S530 to step S530).
544). "Purchasing agent service" means that a purchasing agent handles some or all of the procedures that should be performed with suppliers, such as sales negotiations, provision of goods and services, and payment of goods and services. is there.
The purchase agent notifies the purchaser of the result of the purchase agent (step S536). The purchase agent can receive a reward for performing the purchase agent service from the purchaser (step S540 to step S544). The purchaser needs to pay for the supplier or the distribution / settlement company (steps S546 to S554), but the reward for the purchase agency service here needs to be considered separately.

It is to be noted that the purchase agent service with the purchase agent right may be replaced with a sales site and implemented as a sales agent service with the agent agent.

(4) Purchasing Agent Service with Purchasing Agent Right that Independently Operates the Hall and Agent Management The purchasing agent service with the proxy agent right in this transaction system that insulates the hall operation and agent management makes the operation of the election hall independent. By doing so, the purchase agent candidate can know the presence or absence of the purchase item and the timing of the actualization without depending on the purchaser's system, and independently set the function setting management of the purchase agent candidate This is a service that can automatically perform a proposal activity of a purchase agent candidate. In addition, a plurality of purchase agent candidates can be managed simultaneously.

The role of the “election site” will be exemplified below.・ Manage multiple candidate agents and entry / exit of multiple buyers ・ Convey the existence of buyers who entered the election hall to the candidate agents ・ Existence of candidate agents who entered the election hall・ Transfer to the purchaser candidate the fact that the buyer who has left the election ground has been sent off. ・ The fact that the candidate who has left the election ground (or the selected purchaser) has been sent off. , Tell the buyer

In the present service, non-intervention by the election hall is in principle required. In other words, the election hall provides only a venue and does not intervene in principle with respect to potential purchasers and purchasers. The entry and exit of the purchasing agent (candidate) and the purchaser are based on their respective intentions or settings, and are not basically influenced by the intention of the election hall. However, in special cases, the election hall may be controlled to intervene in the adjustment.

The purchase agent candidates do not have to enter all at once. You can also enter at different times. This also follows the setting of the purchase agent candidate. At the election hall, a plurality of purchase cases may be elected in parallel, but the election hall does not talk about the details of the purchase cases among the procurement agent candidates. In other words, the election hall has no idea what kind of candidate election is being held. For example, "○
It does not have the role of showing the title of the purchase case or the details of the purchase case, such as "election about ○", or coordinating.

In the following, the manager of the purchase agent candidate in the present service manages the execution of the purchase agent candidate. Here, the purchase agent can determine the timing of entry to the election hall, the proposal content, the proposal content modification rule, the purchase agency right fee, and the like.

In order to check actual proposals and service execution contents of the purchasing agent, the process and results of the proposals and service implementation are recorded, thereby coping with defects and troubles and improving the setting method. Can be.

FIG. 6 is a flow chart showing an example of the operation of the transaction system for executing a purchase agency service with a purchase agency right that makes the space management and agent management independent in the present embodiment.

In the transaction system shown in FIG.
Is different from the transaction system shown in (1) in that software for realizing the election hall and software for realizing the manager of the purchase agent candidate are newly added.

The election hall has a function of managing entry and exit of purchasers and purchase agent candidates (step S604, step S610, step S622, step S62).
8, step S654, step S650).

The manager of the candidate agent sets the function of the candidate agent (step S606), and receives the report of the service execution by the candidate agent (step S6).
58) It has a function.

It is to be noted that the purchase agent service with the purchase agent right may be replaced with a sales site and implemented as a sales agent service with the agent agent.

(5) Purchase Proposal Service with Purchase Proposal Right The purchase proposal service with purchase proposal right in the present transaction system is a system in which a purchase proposer who has acquired a purchase proposal right from a purchaser for a fee pays off by performing the purchase proposal service. It is a service that obtains.

[0153] The "purchase proposal" mentioned here does not perform the above-mentioned purchase agency business, but instead obtains a reward by proposing to the purchaser useful information for performing the purchase business.

The reasons why the purchase agency business is not performed (cannot be performed) include, for example, the following.・ If the purchasing agent does not have sufficient ability to perform the purchasing business ・ If there are any restrictions such as contractual relationship between the buyer and the supplier, and it is difficult to perform the purchasing business by a third party immediately. As a result, the proposer can continue to provide the purchasing agency service based on the proposal result. However, this is the case where there is no such restriction.

In the case of performing the purchase agent service, it is also possible to perform the “purchase agent service with purchase agent right” described above.

The advantages of this service will be described below. First, the purchase proposer can regard the amount obtained by subtracting the paid purchase proposal right fee from the purchase proposal service fee as profit. On the other hand, by adopting this service, the purchaser can also reduce the work load for sales negotiations related to the procurement of goods and services, and can derive advantageous profits for himself.

[0157] The contact point of the purchaser is limited to one for one purchase case. However, there may be more than one buyer at the counter. There can be more than one purchase proposer. Further, usually, a plurality of purchasing agents raise one hand and make a proposal.

[0158] The field to which this service is applied is basically the same as the purchasing agency service with the purchasing agency right.

FIG. 7 is a flowchart showing an example of the operation of the transaction system for executing the purchase proposal service with the purchase proposal right in the present embodiment.

First, a purchase proposer candidate is registered (steps S702 to S706). In order to show the buyer that he is a potential buyer,
Apply for purchase proposer registration to the purchaser.

Next, the purchaser presents purchase requirements and provides information to the purchase proposer candidate (step S708). The purchaser presents the purchase requirement to the registered purchase agent, but may provide reference information such as a past sales history based on the purchaser's intention.

Next, a purchase proposal service is proposed to the purchaser by the purchase proposal candidate (step S710).
Step S712). The proposal is described so that the buyer can understand it. The “proposal contents” include, for example, purchase item, purchaser, purchase condition target (specification / quality, delivery date, payment condition, etc.), purchase price target, purchase proposal right fee, reward amount for purchase proposal service, Includes items such as reporting methods and purchase proposal right fees. Here, the purchase proposal right fee is usually plus, but may be minus. Further, the purchase proposal right fee may be paid in points.

Next, the purchaser determines the purchase proposal candidate with the best proposal, and requests the purchase proposal service (steps S714 to S726). The superiority of the proposal is left to the buyer's judgment. Upon request, the purchaser issues a purchasing agency right, and the purchasing agency purchases this right for a fee (purchasing agent right fee) (step S728).

Next, the selected purchase proposer performs a purchase proposal service (step S732 to step S732).
742).

[0165] The "purchase proposal service" is to provide information that is useful for a buyer to negotiate sales and purchase in the future. This is roughly divided into the following two types. One is to predict how suppliers will negotiate sales. Based on the prediction result, the buyer can consider what kind of sales negotiation should be performed. Here are the viewpoints of the sales negotiations here. -How to change the offered price or price that the supplier will do-How to change the conditions other than the price that the supplier will do (specification / quality, delivery date, packing, delivery method, after-sales service, etc.) and how to change it Is based on the prediction and derives and proposes a negotiation method considered to be beneficial for the buyer. For example, there are the following two methods. -How to change the offer price or price on the purchaser's side-How to present conditions other than the purchaser's price (specifications, quality, delivery date, packing, delivery method, after-sales service, etc.) and how to change it The result of the proposal is notified to the purchaser (step S738). The purchase proposer can receive a reward for performing the purchase proposal service from the purchaser (steps S740 to S742).

Note that the purchase proposal service with purchase proposal right of the present embodiment may be replaced with a sales site and implemented as a sales proposal service with sales proposal right.

(6) Purchase Proposal Service with Purchase Proposal Right that Independently Operates the Venue Management and Agent Management The purchase proposal service with the purchase proposal right in this transaction system that makes the venue operation independent of the agent management is provided with the aforementioned purchase proposal right. This is a method in which the operation of the election hall of the purchase proposal service and the function setting management of the purchase proposal candidate are made independent. By making the operation of the election hall independent, the purchase proposer candidate can know the presence or absence of a purchase item and the timing of actualization without depending on the purchaser's system. Also,
By independently providing the function setting management of the purchase proposer candidate, the proposal activity of the purchase proposer candidate can be automatically performed. Further, a plurality of purchase proposer candidates can be managed at the same time.

The role of the “election site” is exemplified below.・ Manage multiple purchase proposer candidates and entry / exit of multiple purchasers ・ Convey the existence of purchasers who have entered the election hall to the purchase proposer candidates ・ Existence of candidate purchase proposers who have entered the election hall To the purchaser ・ Transfer the fact that the buyer who has left the election hall has been removed to the purchaser candidate ・ The fact that the purchaser candidate who has left the electoral ground (or the selected purchaser) , Tell the buyer

In the present service, non-intervention by the election hall is in principle required. In other words, the election hall provides only a venue, and does not intervene to the purchaser candidate and the purchaser. The entry and exit of the purchase proposer (candidate) and the purchaser are based on their respective intentions or settings, and are not affected by the intention of the election hall. However, in special cases, the election hall may be controlled to intervene in the adjustment.

It is not necessary for the purchase proposer candidates to enter all at once. You can also enter at different times. This also follows the setting of the purchase proposal candidate.

At the election hall, a plurality of purchase cases may be elected in parallel. However, the election hall does not talk about the contents of the purchase case between the purchase proposer candidates. In other words, the election hall has no idea what kind of candidate election is being held. For example, it has no role to indicate the title of the purchase case or the details of the purchase case, such as “election for XX”, or to coordinate the purchase.

The role of the manager of the purchase proposer candidate is to manage the execution of the purchase proposer candidate. Here, the purchase proposer can determine the entry timing to the election hall, the proposal content (as described above), the proposal content modification rule, the purchase proposal right fee, and the like.

By recording the process and results of the proposal in order to check the actual content of the purchase proposer, it is possible to deal with problems and troubles in the proposal process and to improve the setting method. .

FIG. 8 is a flowchart showing an example of the operation of the transaction system for executing a sales proposal service with a sales proposal right that makes the space management and the agent management independent according to the present embodiment.

In the transaction system shown in FIG.
Is different from the transaction system shown in (1) in that software for realizing the election hall and software for realizing the manager of the purchase agent candidate are newly added.

The election hall has a function of managing entry and exit of purchasers and purchase agent candidates (steps S804, S810, S824, and S83).
0, step S856, step S856).

The manager of the purchase agent candidate sets the function of the purchase agent candidate (step S806), and receives the report of the service execution by the purchase agent candidate (step S8).
60) Has functions.

It should be noted that the purchase proposal service with a purchase proposal right that makes the space operation and agent management independent of this embodiment is replaced with a sales site, and is a sales proposal service with a sales proposal right that makes the space operation and agent management independent. May be implemented.

(7) Joint Purchasing Service with Purchasing Representative Right The joint purchasing service with purchasing representative right in the present transaction system is a joint purchasing (purchasing and distribution) system in which a purchasing representative who has acquired a purchasing representative right from a purchaser for a fee is paid. A service that earns rewards through performance. In addition, it is not simply a joint purchase (purchase + distribution) service, but a joint purchase is carried out after obtaining the authority to execute the joint purchase service for a fee. For the purchasing representative, in order to regain the fee for acquiring the purchasing representation right, this is a system in which an incentive works to lead the buying and selling negotiation more advantageously to the buyer.

There are the following three points different from the above-mentioned "purchasing agent service with purchasing agent right". 1. 1. The primary buyer as seen from the supplier is the purchasing representative (that is, the purchasing representative is at risk of purchasing). 2. The purchase representative (primary purchaser) does not need to disclose to the supplier at the time of purchase that the secondary purchaser who is the distribution destination is the purchaser. The point that the purchasing representative does not need to disclose the price at the time of distribution to the secondary purchaser (including the distribution unit price) to both the supplier and other secondary purchasers at the time of distribution.

The merit of this service is that the purchasing representative can see the difference between the distribution and the profit. Here, a relationship of “difference generated by distribution” = “total amount of goods collected from distribution destination” − “article purchase price paid to supplier” is established. On the other hand, by adopting this service, the purchaser can also reduce the work load for sales negotiations related to the procurement of goods and services, and derive advantageous profits by reducing the purchase price.

There are a plurality of purchasers for one purchase case. Purchasing representative candidate (before purchasing representative is decided)
Although there are a plurality of buyers, the number of grantees of the purchasing representative right is narrowed down to one.

The field to which this service is applied is basically the same as the purchasing agency service with the purchasing agency right.

FIGS. 9 and 10 are flowcharts showing an example of the operation of the transaction system for executing the joint purchase service with the purchase representation right in this embodiment.

First, the buyer (plural) firstly
The purchase representative candidate is notified that the purchase case is scheduled (steps S902 to S904).

Then, a purchase representative candidate is registered (steps S906 to S910).

Further, the purchase representative candidate applies for registration of the purchase representative registration to the secondary purchaser in order to indicate to the secondary purchaser that the candidate is a purchase representative candidate (step S908).

Subsequently, the purchaser presents the purchase requirement to the purchase representative candidate and provides information (steps S912 to S912).
Step S916). The secondary purchaser presents purchase requirements to the registered purchase representative candidates. Further, based on the intention of the secondary purchaser, reference information such as a past trading history may be provided.

Next, a suggestion of a joint purchase service to the secondary purchaser is made by the purchase representative candidate (step S).
916). The content of the proposal is described so that the secondary purchaser can understand it. The “proposal contents” include, for example, purchased item, purchaser, distribution condition target (specification / quality, delivery date, payment condition, etc.) to the secondary purchaser, distribution price target to the secondary purchaser, purchase representative right fee (Payment to the secondary purchaser), remuneration system of distribution service (for example, the following system is conceivable: remuneration for implementation of distribution service, that is, remuneration for performing service, distribution profit, ie, profit generated by distribution (distribution) (Some or all of the total price-purchase price) is considered as a reward), the method of reporting the proposal content, and the setting of the purchasing representative right fee. Here, the purchasing representative right fee is
Usually plus, but may be minus. The purchasing representative right fee may be paid in points.

Next, the purchaser determines the purchase representative candidate with the best proposal, and requests the joint purchase service (steps S918 to S936). The superiority of the proposal is left to the buyer's judgment.

At the same time as the request, the purchaser issues a purchasing agency right, and the purchasing agency purchases it for a fee (distribution right fee) (steps S938 to S940).

Next, the selected purchasing representative performs joint purchasing (steps S942 to 964). In “joint purchasing”, the purchasing representative will handle procedures such as sales negotiations, provision of goods and services, and payment for goods and services that should be performed with suppliers. Also, the purchasing representative has the risk of purchasing from the supplier.

Next, the purchasing representative distributes the jointly purchased goods and services to the secondary purchaser (step S94).
4 to Step S946). The amount and method of distribution will depend on the intended secondary buyer's wishes.

Next, the purchase representative receives a reward. Here, there are the following three methods for receiving a reward. 1. Method of receiving and receiving bills separately from the billing of goods and services (step S950 to step S950)
964). 2. A method for billing and receiving as part of the goods / services price (step S transaction management center 1002 to step S1024). In this case, the secondary purchaser does not see the distribution service fee. 3. Combining the methods 1 and 2 to separate the billing for goods and services and billing as part of the goods and services (not visible to secondary purchasers)
(Step S1026 to Step S1026)
1054).

Through this service, the purchasing representative can see the amount obtained by subtracting the paid purchasing representative right fee from the distribution service fee as revenue.

Note that the joint purchase service with the purchase representation right of the present embodiment may be replaced with a sales site and implemented as a joint sale service with the sales representation right.

(8) Joint Purchasing Service with Purchasing Representation Right that Independently Operates Shop Management and Agent Management The joint purchasing service with purchasing representation right that makes shop management and agent management independent in this transaction system has the above-mentioned purchasing representation right. This is a service that separates the operation of the election hall of the joint purchasing service and the function setting management of the purchasing representative candidate. By making the operation of the election hall independent, the purchase representative candidate can know the presence or absence of a purchase item and the timing of actualization without depending on the purchaser's system. Further, by independently providing the function setting management of the purchase representative candidate, the proposal activity of the purchase representative candidate can be automatically performed. Also, a plurality of purchase representative candidates can be managed simultaneously.

The role of the election hall is exemplified below.・ Announce the plan of the joint purchasing service drafted by (Purchase Representative candidate function setting manager) ・ Manage multiple Purchasing Representative candidates and manage the entrance and exit of multiple buyers ・ Enter the election hall Notifying the purchasing representative of the existence of the buyer who has entered the election hall ・ Informing the buyer of the existence of the purchasing representative candidate who has entered the election hall ・ The candidate of the purchasing representative who has exited the election hall・ Inform the buyer of the fact that the candidate of the purchasing representative who has left the election hall (or the selected purchasing representative) has left.

In this service, non-coordination by the election hall is in principle required. In other words, the election hall provides only the venue and does not intervene with the purchasing representative candidate and the buyer. However, in special cases, the election hall may be controlled to intervene.

The entry and exit of the purchase representative (candidate) and the purchaser are based on each intention or setting, and are not affected by the intention of the election hall. Purchasing representative candidates do not have to enter all at once. You can also enter at different times. This also follows the setting of the purchase representative candidate.

At the election hall, a plurality of purchase cases may be elected in parallel, but the election hall does not talk about the contents of the purchase case between the purchasing representative candidates. In other words, the election hall has no idea what kind of candidate election is being held. For example, it has no role to indicate the title of the purchase case or the details of the purchase case, such as “election for XX”, or to coordinate the purchase.

The role of the manager of the purchase representative candidate is exemplified below.・ Draft a joint purchasing service plan. The plan will be announced to buyers through the election hall. The plan also specifies election rules.

The manager manages the execution of the purchase representative candidate. Here, the purchasing representative candidate includes the timing of entering the election hall, the proposal content (as described above), the proposal content modification rule,
You can decide the purchasing representative right fee.

In order to check the actual proposals and service execution contents of the purchasing representative, the manager records the proposals and the service implementation process and results in a record, thereby coping with defects and troubles, and setting the method. Can be improved.

The manager selects a purchase representative candidate.
That is, if the number of candidates whose proposals are satisfied is divided into some among the buyers, candidates are selected. Disagreeing groups (buyers who disagree with the final selected candidate) will not be forced to participate in the service (such buyers will be removed). However, there is a way for the manager to re-propose to the disapproving group that a candidate supported by the disapproving group should be set aside and treated as another joint purchase.

FIGS. 11 and 12 are flowcharts showing an example of the operation of the transaction system for executing the joint purchasing service with the purchasing representation right that makes the space management and agent management independent in the present embodiment.

In the trading system shown in FIGS. 11 and 12, the trading system shown in FIGS.
The difference is that software for realizing the election hall and software for realizing the manager of the purchasing agent candidate are newly added.

The election hall has a function of managing entry and exit of purchasers and purchase agent candidates.

The manager of the purchase agent candidate drafts a joint purchase service plan (step S1102), sets the function of the purchase agent candidate (step S1110), and selects a purchase representative based on the plan (step S1110). Step S113
0), and has a function of receiving a report of service execution by the purchase agent candidate (step S1160, step S1222, step S1254).

[0210] The joint purchase service with a purchase representative right that makes the store operation and agent management independent of this embodiment is replaced with a sales site, and is a joint sales service with a sales representative right that makes the store operation and agent management independent. May be implemented.

(9) Simultaneous assignment service of purchasing agency right and sales agency right The simultaneous assignment service of purchasing agency right and sales agency right in the present transaction system allows distributors who want to obtain the handling authority even for a fee, to the supplier This service is selected based on the judgment of both buyers. In this service, suppliers, distributors and buyers enter, and when a sales transaction is performed between the supplier and the buyer, an appropriate distributor is selected through a center provided on the Internet. is there.

The combination unit of the participants in the system is
One supplier: n distributors (plural companies): one purchaser.

[0213] Distributors are not selected based on one-sided notification from either the supplier or the purchaser, but are selected based on an agreement between the two. Many existing distributors have investor relationships with suppliers and buyers, kickback systems, point systems, etc., and will either stick to suppliers or buyers or stick to the system Increasing trends will result in less flexibility for suppliers and buyers to choose distributors. In this method, a distributor selected by agreement between both the supplier and the buyer conducts the transaction.

[0214] The selected distributor can perform exclusive or preferential sales negotiations by obtaining the sales agency right from the supplier and the purchasing agency right from the purchaser.

The suppliers, purchasers, and distributors are all connected via a network such as the Internet, and the above-described appointment procedure is automatically performed through a center provided on the Internet, so that the efficiency of the appointment is improved. Appointment procedures can be performed.

[0216] As a background situation in which a supplier and a purchaser use a distributor, for example, there are the following cases. -Cases in which buyers do not like direct transactions (cases in which they want to reduce the burden of administrative tasks associated with transactions)-Cases in which suppliers do not like direct transactions (in which they want to reduce the burden of administrative tasks associated with transactions, or increase sales through channel development) Case that focuses on)

The role of the center in this service will be described below. 1. All suppliers, distributors and buyers participating in the service are registered with the center. Suppliers, distributors, and buyers can communicate and record in one of two ways:
One is a method in which communication is performed via a center and a record is left in the center, and the other is a method in which communication is performed without the center and a record of the communication is immediately delivered to the center. It is. 2. Communication between suppliers, distributors and buyers is recorded at the center. 3. Registration of a distributor candidate list (including various conditions) is performed. Register candidate distributors and sales requirements based on supplier wishes. In addition, a distributor candidate list and purchase requirements can be registered based on the purchaser's request. further,
An input / change form for automating the registration procedure can be automatically generated. 4. Set the sales agency right fee and the purchase agency right fee. You can register sales agency fees and purchasing agency fees based on the distributor's wishes. This registration content can be changed according to the case and the destination (sale destination, supplier). Further, an input / change form for automating the registration procedure can be automatically generated. 5. Distributor profile information is stored and can be referenced by suppliers and buyers as needed. The information can be added or modified by each supplier and each purchaser at their own convenience. Further, the shared part and the non-shared part can be separated as necessary. 6. Sales agent fees and purchasing agent fees can be collected as deposits from distributors. Withdrawing the sales agent right and purchasing agent right from the deposit,
Pay suppliers and buyers. 7. If the deposit is not used, a distributorship fee and a purchasing agency fee can be charged to the distributor. Payment based on billing and confirmation of receipt can also be made through the center.

Next, the registration items of the supplier and the purchaser to the center are exemplified below. 1. Distributor Candidate Name Candidate names can be given by one of the following policies. (1) Positive list (if the name of the desired candidate is given and selection from them is permitted) (2) Negative list ( 1. Names you do not want and prohibit selection from them (in other words, names from other sources are allowed). Distributor profile information Information registered by suppliers and purchasers at their convenience. You can register information that is visible only to each supplier or each purchaser. 3. Terms and conditions This includes, for example, the expiration date on which the proxy fee is valid, the qualifying transaction, the terms of delivery from and to the supplier (only suppliers can be seen), the terms of delivery to the buyer. And billing conditions for the purchaser (only the purchaser can be seen).

Next, the registration items of the distributor candidate to the center are exemplified below. 1. Sales Agent Fee and Purchase Agent Fee It cannot be seen by other distributors. 2. Payment method This includes a method of paying sequentially by invoice, a method of pooling a considerable amount of money in advance at the center by deposit and debiting it at the time of billing.

There are restrictions on the values of the sales agency right fee and the purchase agency right fee. The sales agency fee and the purchase agency fee may be negative values. That is, depending on the power relationship between the distributor and the supplier or the power relationship between the distributor and the buyer, the proxy right may be set to a negative value. A negative value means that the distributor will "get" the agency fee instead of paying the agency fee. Further, one or both of the sales agency right fee and the purchase agency right fee may be omitted.

FIGS. 13 and 14 are flow charts showing an example of the operation of the transaction system for realizing the simultaneous assignment service of the purchasing agency right and the selling agency right in the present embodiment.

First, a sales (purchase) intention is displayed, and a distributor is registered (step S130).
2 to step S1330). There will be direct discussions on goods and services transactions in the pre-negotiation activities between buyers and suppliers. Both buyers and suppliers prefer to trade via distributors based on their wishes. The center generates an entry form for registration and prompts suppliers and buyers to register. According to the input form, suppliers and buyers register the desired distributor.
Suppliers and buyers can query distributor profiles through the center.

Next, a sales agency right fee and a purchase agency right fee are set (steps S1332 to S134).
6). The center generates an input form for setting and urges the registered distributors to set. According to the input form, the distributor sets a sales agency right fee and a purchase agency right fee, and applies to the center.

Next, the optimum distributor is selected (steps S1348 to S1352). An optimal distributor is automatically selected from registered distributors based on a selection logic.
The selection logic is determined in advance based on the agreement between the supplier and the purchaser. The selected distributor will automatically be given the right to sell,
The purchaser is granted the right to act on behalf of the buyer. One or more distributors may be selected. In the case of a singular, exclusive delegation rights can be obtained. In the case of a plurality, it is possible to obtain preferential agency rights. However, unless there are special conditions, they will have equal rights. The selected distributor does not guarantee any exclusive or preferential agency right to the distributor requested by a route other than this system. Exclusive and preferential agency rights are guaranteed only by distributors via the system. The selected distributor can refuse to receive sales agency rights and purchasing agency rights. The refusal is at the discretion of the distributor and there is no particular need to disclose the reason.

Here, as specific circumstances leading to refusal, for example, the following can be considered.・ If the trading price is uncertain and profits are deemed to be poor after deduction of proxy rights ・ If competition between distributors is severe and profitability is not expected

Next, goods and services are traded via the distributor.

Here, prior to the transaction of the goods and services, the payment of the sales agency right fee and the purchase agency right fee described below may be paid.

[0228] Through the center from the distributor, the sales agency fee is paid to the supplier, and the purchase agency fee is paid to the purchaser.

In the case of making a payment by deposit, the sales agency right and the purchase agency right can be deducted from the money deposited in advance at the center as a deposit from the supplier or the purchaser (step S1402). Step S1418).

[0230] If the deposit is not paid, the center issues a bill to the distributor. The sales agency right fee and the purchase agency right fee are paid based on the bill (steps S1424 to S1430).

Here, the sales agency right fee can be processed by being included in the payment of the goods and services to the supplier. In addition, the purchase agency right fee can be processed by subtracting it from the purchaser's bill for goods and services.

If automatic selection of the distributor by the center is impossible, the process is repeated from the distributor registration. When automatic selection proves impossible, the center informs suppliers and purchasers of it.

Under the permission of the supplier, the center can disclose the list of distributor candidates desired by the supplier to the purchaser. Under the permission of the purchaser, the center can disclose the distributor candidate desired by the purchaser. The center can disclose the supplier list to the supplier (step S1432 to step S14).
36). Suppliers and buyers re-register as distributors and have centers automatically select them. If the distributor who satisfies the selector does not appear after repeating any of the above methods, the service is terminated.

Next, an example of the distributor automatic selection logic described in steps S1348 to S1352 in FIG. 13 will be described below.

First, distributors satisfying both are extracted from the candidate list registered by the supplier and the purchaser. At this time, the extracted candidate is 1
If it is a name, it will be automatically nominated as a distributor, but if there are two or more extracted candidates, priority will be given among them and the best distributor will be selected .

Next, as a methodology for selecting an optimal distributor from two or more distributor candidates, for example, the following method can be considered.

First, scoring is performed based on an additional item or a deducted item. In other words, the center specifies items such as past performance (delivery, payment, sales follow-up, etc.) and the expected effects of the transaction (strengthening relationships, nurturing effects, etc.), and provides a scoring form to suppliers and buyers. Distribute (this can be done at the same time as distributor registration).

Next, the supplier and the purchaser assign a quantitative evaluation score to each distributor according to the scoring form.

Then, the center calculates the total point addition and the total point deduction, and ranks the distributors based on the calculation results, and selects the optimal distributor.

For example, in the following case, the automatic selection logic changes little by little depending on the method of presenting the distributor candidate list of the supplier and the purchaser. -In the case of positive list x positive list (when both the supplier and the buyer register the positive list) It is possible to adopt the selection logic as described above.・ In the case of a positive list x negative list (when one of the supplier and purchaser registers the positive list and the other registers the negative list) From the list obtained by subtracting the names listed in the negative list from the positive list, Take the selection logic as follows. -In the case of negative list x negative list (when both the supplier and the buyer register the negative list) Since neither the supplier nor the buyer has the desired distributor, the center presents a candidate distributor. Subtracts the names appearing on both negative lists from the list registered in advance, and sets this as a temporary positive list. Then, the temporary positive list is notified to the supplier and the purchaser. The supplier and the purchaser newly register the positive list based on the provisional positive list (they also perform the scoring based on the added items and the deducted items), and then take the above selection logic.

(Regarding a case where part of the decision flow of the owner relating to the selection of the agent is transferred to the coordinating place or the election hall) The following decision may be made in the form provided by the function of the owner. May be transferred to a coordinating place or election hall that is set up independently of this.・ Extraction of agent candidates and judgment of prioritization ・ Judgment of quality of service proposed by agent
