Description

Construction project financial management system based on super account book structure and chain code solution
Technical Field
The invention belongs to the technical field of financial management, and particularly relates to a construction project financial management system based on a super account book structure and a chain code solution.
Background
The cash management of construction projects has many problems, mainly including: owner slow/partial payment; the employer withholds the term payment; a payment term issue upon obtaining payment; human error in submitting invoices; delays in payment due to contractual issues and customer unfair practices; the customer abusing a defect period of responsibility (DLP) to retain the remaining payments; and the use of construction information modeling (BIM) is required to develop reliable project cash flows.
Recently, blockchains have been introduced as a kind of distributed ledger, which is implemented by scattering information among all network elements. All information will be automatically approved by an approved consensus mechanism that is automatically shared among the participants according to the agreed ranking policy.
The prior art has the following problems: existing financial management systems do not provide a comprehensive solution in the following respects:
1. providing intelligent contract functions for all parties (namely clients, contractors and subcontractors);
2. automating the reporting during a checkout phase to determine remaining financial obligations;
3. BIM integration is used as a cost information source;
4. intelligent contract functionality is provided to manage the remaining tasks during the defect liability period.
Disclosure of Invention
To solve the problems raised in the background art described above. The invention provides a construction project financial management system based on a super account book structure and a chain code solution, which has the characteristics of safe transaction, record, no need of participation of a third party and guarantee of automatically controlling residual finance in a defect responsibility period by a non-owner through a pre-agreed endorsement policy.
In order to achieve the purpose, the invention provides the following technical scheme: construction project financial management system based on super account book structure and chain code solution, construction project financial management system structure is as follows:
s1, the framework development based on the super account book structure and the chain codes comprises the following steps: trade contracts of different business construction parties under the traditional contract and design-construction method and all requirements of BIM to block chain;
s2, respectively designing intelligent contracts made based on transactions as follows: the construction transaction structure based on the chain code is constructed by the main contractor to the owner, the owner to the contractor, the contractor to the subcontractor and the supplier;
s3, the block chain and intelligent contract component structure is designed as follows: setting the endorsement policy parameters based on BIM of the endorsement policy;
s4, construction project handover-based super account book structure system: supporting an automatic calculation checkout stage in view of all approved transactions being recorded in the ledgers of both parties;
s5, consistency of a dispersed financial system and a construction delivery stage: the scattered financial concept proves that the development is carried out in the whole construction project delivery stage, and the difference between the characteristics of the payment method needs to be considered, particularly the one-time total payment and the cost plus/target cost;
according to S1-S5, the establishment of the intelligent contract based on the transaction comprises the following steps: in the construction process, a block chain is adopted, a mathematical model needs to be developed to quantify all potential transactions representing different financial tasks, and the transactions in the invention are designed to meet the traditional contract and design-construction method, so that the applicability and the expandability of a proposed system are ensured; furthermore, the proposed trade is designed in the BIM dimension, i.e. the results of the 4DBIM (planning and design) dimension and the 5DBIM (cost management) dimension are considered to determine the value of the trade; these transactions are divided into the following specific parts:
the main contractor is to the owner: invoices submitted by the general contractor throughout the project lifecycle; if the traditional contract mode is adopted, the general contractor should submit the invoice in the construction and ending stages; for the design-build approach, the prime contractor may submit invoices throughout the design, construction, and finalization phases; equation 1 shows the structure of a payment request made by a prime contractor to a customer;
Ti,n=(VCWn+MV)-(RV) (1)
wherein T isi,nIs a request for payment on project i that project has completed in the nth month, VCWnIs the monetary value of the completed project in the pay milestone n, MV is the added value, RV represents all contractsThe value of reserved gold is agreed; after the contractor's representative invokes a transaction, the transaction should be automatically checked according to an agreed negotiation consistency mechanism (i.e., time to collect the transaction, range of transaction value, etc.);
owner-to-contractor: owner-to-contractor transactions respond to a previous "contractor-to-owner" transaction, and therefore synchronization between the two transactions should be considered; thus, if the contractor invoked transaction is rejected, then the owner to contractor transaction should not be invoked;
contractors divide contractors and suppliers: whereas blockchain networks enable network parties to share different information between particular parties through designated channels, a contractor may include subcontractors and suppliers in a single blockchain of a project; all accumulated data will be encrypted and not available to all other parties (e.g., owners and consultants); the parameters of the intelligent contract transaction should be designed to include the name of the subcontractor/supplier and an indication of the construction trade package; in design-build and traditional control methods, subcontractors and suppliers typically do not participate in early design and build; thus, the transaction parameters should include their company name and transaction package (i.e., ceiling package, lighting and light package, etc.);
construction transaction structure based on chain sign indicating number: the structure of proposed chain codes includes three categories, namely: adding one party, particularly a subcontractor at a construction stage, in a project network; a financial transaction; and querying the transaction; since the parameters of the transaction are available in the construction phase, the proposed intelligent contract is consistent with both design-construction and traditional contracts;
block chain and intelligent contract component structure: designing a super book structure component, including endorsement and ordering strategies; given that BIM is used to retrieve progress and cost data (4D and 5 DBIM), the interrelationship between BIM and blockchain system must be considered;
BIM based on endorsement policy: transactions may be accepted or rejected according to conventions in the super ledger structure; these conditions are referred to as endorsement policies; the super account book structure is a suitable platform for developing a construction project cash flow system; therefore, the process of endorsement and order transaction should be consistent with the construction process; the process begins with a call transaction; such transactions must comply with agreed-upon endorsement policies and then the endorsed transactions are distributed to committed associates (i.e., owners, contractors, subcontractors) through designed channels; three main channels should be designed in the construction engineering method to provide high level of privacy for each party, namely: channel 1 transfers approved transactions from contractors to owners (the parties involved may be contractors, owners and consultants); channel 2 transfers approved transactions from the host to the contractor (which may include the same members as channel 1 so that the consultant can track financial movements in all projects); channel 3 connects the prime contractor and all other subcontractors; thus, depending on the number of subcontractors and suppliers involved, this channel may be more than one (if the subcontractor is domestic, rather than designated, the consultant and owner may not be involved here);
and (3) endorsement policy parameters: each transaction must satisfy two main conditions, namely the time the transaction was invoked and the value of the transaction; therefore, there should be a correlation between the results of 4D and 5DBIM and the super ledger consensus mechanisms, including endorsement and subscription policies; 4DBIM is used to retrieve each milestone payment information for each transaction package in the project; meanwhile, with the 5DBIM model: calculating an estimated cost and an actual cost for each milestone and each trade package; calculate performance percentage, because it is a parameter that should be submitted with the contractor to owner transaction;
the endorsement policy includes three main parameters: time, monetary value, and project performance percentage; the methodology proposed in this framework enables contracting parties to link project performance with the acceptance/rejection of each payment per milestone; this may allow the primary project party to avoid disputes if there is additional payment (the payment method is the target cost);
super account book structural system based on construction engineering project hands over: given that all approved transactions are recorded in both parties' ledgers, it can support an automated computing checkout phase; accounting for financial obligations and rights not fulfilled by all parties to the project, according to the adopted and agreed payment method (i.e. lump sum, cost addition, etc.); for a lump sum, the financial checkout will be direct; all parties can call the inquiry transaction to check the accumulated payment and compare the accumulated transaction value with the agreed contract value; first, the owner and contractor should check the received reimbursement costs against agreed project values, including price and agreed add-on; if the party agrees to pay all of the invoices, the blockchain network and the intelligent contract may receive a percentage of retention; however, when unpaid invoices are not paid in full, the intelligent contract may be used to obtain those invoices, and the ending phase will be suspended until all financial responsibility is delivered;
in formulating an approval policy, the epilogue phase should be considered by adding approval parameters (such as DLP); thus, any transaction that is invoked after a contracted date should be automatically rejected; if a one-time pay-as-you-go approach is used, the remaining financial Responsibility (RFD) that the owner should pay should be calculated by determining the cumulative value (AV) owed by the owner (i) to the underwriter (J) for all project and the project transaction value (APTV) accepted by the owner (i) to the underwriter (J); in case of the cost-add/target cost payment method, the Paid Profit (PP) should be calculated by determining a difference between the APTV and the paid Project Cost (PC) from the customer (i) to the contractor (j), and then estimating a remaining profit value;
consistency of the dispersed financial system with the construction delivery phase: the dispersed financial concept proves that the development is carried out in the whole construction project delivery stage; taking into account differences between the characteristics of the payment method, in particular the lump sum and the cost plus/target cost; in the construction phase, the transaction process is repeatedly invoked for each payment milestone; three transactions should gather their interrelationships; if the contractor's transaction to the owner is denied, neither the owner's transaction to the contractor nor the subcontractor's transaction to the contractor should be referred; this can ensure consistency between all cost accounting systems of all parties; even if the same transaction should be collected for the last payment in the checkout phase, certain checks must be completed before the DLP session begins; thus, the yield can be estimated.
Compared with the prior art, the invention has the beneficial effects that:
the invention introduces a decentralized financial management system, uses the block chain technology to process all financial tasks of each construction stage, and under different delivery modes and payment modes, the proposed system enables each party to safely and automatically record/call the transaction without the participation of a third party; the proposed method allows non-business owners to automatically control the financial rights remaining during the Defect Liability Period (DLP) through pre-agreed endorsement policies; the system has the ability and operability to provide a secure and extensible platform for all project parties.
