[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0037] See also Figure 1 , Figure 1 A schematic diagram of a process flow of a construction claim method provided by an embodiment of the present invention;

[0038] like Figure 1 As shown, the method includes steps S101 to S105.

[0039] S101. Collect historical claim cases and establish a claim case database;

[0040] S102. Extract the causes of claims from historical claim cases and establish a database of the causes of claims;

[0041] In steps S101-S102, historical claim cases are collected and stored according to their characteristic categories. A claim case database is then established. This classification can be categorized by project type, such as building construction or water conservancy. The causes of claims are extracted from these historical claim cases. These are non-contractor factors encountered during the project that cause the contractor to incur expenses or time losses, such as delayed start, cost increases, and design changes. A claim cause vocabulary is then created based on the extracted claim causes for each historical claim case. This construction of a claim case database and claim cause vocabulary facilitates subsequent query matching.

[0042] S103. Match the claim cause of the pending claim case in the claim cause database, and find all historical claim cases containing the claim cause of the pending claim case in the claim case database based on the matching results, and use all the found historical claim cases as reference cases for the pending claim case;

[0043] In step S103, the case to be claimed is a case that needs to be analyzed for claims in this application. It can be a case that is under construction or a case after the construction is completed. By performing query matching through various matching methods such as project category matching, field matching, and word meaning recognition, multiple reference cases to be claimed can be obtained. This provides accurate reference objects for subsequent mathematical analysis, thereby improving the success rate of claims.

[0044] S104. Extract the claim cause chain in each pending claim reference case and construct a claim cause network;

[0045] S105. Perform mathematical analysis on each claim cause chain and claim cause in the claim cause network to obtain a response strategy for the pending claim case;

[0046] S106. Outputting a successful case containing the claim cause of the pending claim case from the pending claim reference case, extracting the claim evidence and claim standard of the successful case and using it as a claim reference for the pending claim case.

[0047] Steps S104-S106 are the process of constructing a claim cause network, then mathematically analyzing the claim cause network and providing a claim reference. This effectively utilizes the big data information of the claim case library and analyzes the relationship between the claim cause network and the claim causes of the pending claim cases, providing important reference and decision-making assistance for the construction party to avoid risks in a timely manner, seize claim opportunities and successfully file claims.

[0048] The process of constructing the claim cause network in step S104 is further described below. Figure 2 As shown, for each reference case to be claimed, follow the steps below:

[0049] S201. Read the claim reason in the reference case to be claimed;

[0050] S202, extracting key claim information from the claim reason and obtaining the claim cause;

[0051] S203. Form a claim cause chain according to the order in which the claim causes occur;

[0052] Steps S201-S203 describe the process of extracting the claim cause chain from the reference case to be claimed. For ease of understanding, a specific embodiment is used for illustration:

[0053] For example, in a reference case where a claim is pending;

[0054] The reason for the claim read was: the owner failed to provide the production and living space for the mechanical and electrical installation section on time, which resulted in the contractor taking two months to start work after arriving at the base, increasing costs.

[0055] Three causes of claim can be raised from the reasons for the claim: failure to provide the construction site on time, delayed start of work, and increased costs.

[0056] The chain of causes of the claim is: failure to provide the construction site on time → delayed start of work → increased costs → claim;

[0057] It should be noted that there may be one or more claim cause chains in a reference case to be claimed.

[0058] Finally, all the claim cause chains in all pending claim reference cases are combined, and a claim cause network represented as an adjacency matrix is ​​constructed with the claim causes as nodes.

[0059] The following is a specific example to introduce the process of constructing a claim cause network;

[0060] First, we introduce the causes of claims in the reference cases to be claimed, as shown in Table 1 (only the parts that need to be exemplified are shown). In addition to Table 1, it also includes the causes of claims under multiple main factors such as design procurement, external risks, contract project definition, etc.

[0061] Table 1

[0062]

[0063]

[0064] For example, the claim in the input pending claim case is caused by engineering change (N1). In the pending claim reference case, the engineering change (N1) will directly lead to an increase in engineering volume (P1) and an increase in cost (P2), that is, (N1, P1) and (N1, P2) are equal to 1.

[0065] like Figure 8As shown, by integrating all claim cause chains, a complete adjacency matrix is ​​generated. The first row and first column of the adjacency matrix are claim causes, representing the nodes of the claim cause network. The non-diagonal cells of the adjacency matrix represent the relationship between two claim causes. If a claim cause causes or affects another claim cause, the value of the corresponding cell is equal to 1, otherwise, the value is 0. All diagonal cells are equal to 0 because the claim cause has no relationship with itself. The adjacency matrix is ​​input into the UCINET 6 for Windows version software, and the claim cause network can be drawn using NetDraw (network analysis and visualization tool). The software can also analyze the characteristic parameters of the claim cause network (node ​​degree, clustering coefficient, network density, etc.).

[0066] The following describes step S105, specifically the process of mathematically analyzing each claim cause chain and claim cause in the claim cause network. Step S105 includes:

[0067] Count the categories and occurrence times of each claim cause chain in the claim cause network, and use a weighted algorithm to calculate the next potential claim cause of the pending claim case;

[0068] Among them, such as Figure 3 As shown in Figure 2, the calculation process of the weighted algorithm is as follows:

[0069] S301. Confirm the claim cause of the pending claim case is the next claim cause in each claim cause chain, and use the next claim cause in each claim cause chain as the claim cause to be calculated in the claim cause chain;

[0070] S302: Multiply the number of occurrences of each claim cause chain by the number of categories of the claim cause chain with its own claim cause to be calculated, and obtain the calculation result of the corresponding claim cause to be calculated;

[0071] S303: The to-be-calculated claim cause with the largest calculated result is used as the next potential claim cause of the to-be-calculated claim case.

[0072] In this embodiment, the purpose of using the above-mentioned weighted algorithm is to predict the next potential claim cause of the claim cause of the pending claim case, so as to know the most likely development of the pending claim case and make preparations in advance, such as dealing with risks and preparing claim supporting materials.

[0073] In one embodiment, if Figure 4 As shown, step S105 further includes:

[0074] S401. The first claim cause in each claim cause chain is regarded as the originating factor;

[0075] S402. The claim cause with the most correlations and the claim cause with the highest betweenness centrality in each claim cause chain is selected as the key claim cause;

[0076] S403. The collection direction of claim materials for pending claim cases shall be based on origin factors and key claim causes.

[0077] This embodiment mainly analyzes the relationship between each claim cause in each claim cause chain, such as Figure 8 In the figure, it can be seen that the engineering change (N1) with only output but no input is the origin factor, that is, the node with only out-degree but no in-degree is the origin factor that causes the claim. The contractor can analyze whether it has fallen behind this factor and supplement the relevant supporting materials as soon as possible. The cost increase (P2) has four edges, indicating that it is a key transportation hub and other information. The node with the highest total degree (total number of edges) and the node with the highest betweenness centrality are regarded as the key claim causes; therefore, the origin factors and key claim causes are nodes with great influence and must be focused on. Therefore, the direction of claim material collection for pending claim cases can also be based on the origin factors and key claim causes.

[0078] In one embodiment, if Figure 5 As shown, step S105 further includes:

[0079] S501. Calculate the clustering coefficient of the claim cause of the pending claim case in the claim cause network, where the clustering coefficient of the claim cause of the pending claim case refers to: the probability that two neighboring nodes of the claim cause of the pending claim case in the claim cause network are connected to each other;

[0080] S502: Select the neighbor node corresponding to the maximum probability as the claim response direction of the pending claim case.

[0081] In this embodiment, the largest or top-ranked neighbor nodes are selected based on the clustering coefficient. These neighbor nodes have high connectivity with the claim causes of pending claims and are easily influenced by each other. In claims management, emergency and prevention plans for these nodes should be prioritized to better control and manage claims.

[0082] In one embodiment, if Figure 6 As shown, step S106 includes:

[0083] S601: Outputting a preset number of successful cases containing the claim cause chain of the pending claim case from the pending claim reference cases;

[0084] S602: Extract the calculation formula of the claim amount, claim evidence and claim negotiation process in the successful case and use them as a reference for the claim case to be claimed.

[0085] In this embodiment, the main purpose is to further output the successful case that best meets the reference of the case to be claimed. The case to be claimed can have one or more claim cause chains. The specific claim cause chain can be output from the claim cause network based on the results of the aforementioned mathematical analysis, or it can be selected by the user from the claim cause network.

[0086] Based on the claim process of successful cases, you can refer to the calculation formula for the claim amount, claim evidence materials, how to communicate and negotiate with the owner, and other strategies, and apply them to the cases to be claimed; of course, you can also output cases with the same claim cause chain as the cases to be claimed and failed claims, and output the reasons for the failure, lessons and experience summary. The output content can all be presented in the form of a report.

[0087] In addition, the present invention can also output the claim success rate, such as Figure 7 As shown, specifically including:

[0088] S701. Confirm one or more claim cause chains of pending claim cases;

[0089] S702. Calculate the proportion of all successful cases corresponding to each claim cause chain in all pending claim reference cases to obtain the claim success rate of the corresponding claim cause chain;

[0090] S703. Filter claim cause chains exceeding a preset ratio as claim cause chains for pending claim cases to be executed.

[0091] In this embodiment, there are one or more claim cause chains in the pending claim case, and usually the claim success rate of each claim cause chain is different. After calculating the corresponding claim success rate of each claim cause chain in the pending claim reference case, the claim cause chains that exceed the preset ratio are selected. The preset ratio here can be set according to specific needs. The claim cause chains that exceed the preset ratio are used as the claim cause chains when executing the claim for the pending claim case. That is to say, the success rate of using the claim cause chains that exceed the preset ratio to claim is relatively higher, thereby maximizing the claim success rate.

[0092] The embodiment of the present invention further provides a construction claim device, which is used to execute any embodiment of the above-mentioned construction claim method.
