[0002] In project management, cash flow forecasting is an important basis for arranging capital investment. Existing cash flow forecasting methods are usually based on the total revenue in the bill of quantities, which is simply spread out to each month. Although this method is simple, it ignores the actual resource consumption of the project, resulting in large forecast deviations. Since the price and consumption of resources in the project will change according to different time nodes, the traditional spread method cannot accurately reflect the actual cash flow of the project, which in turn affects the project's capital management, risk control and ultimate profit.

[0003] In order to solve this problem, cash flow forecasting methods based on resource consumption have been gradually introduced into the existing technology. However, these methods often only consider the usage of resources. Therefore, the accuracy of cash flow forecasting is still insufficient and cannot provide a reliable basis for project management.

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1A flowchart of a method for predicting project cash inflows based on human, material and machine resources under a bill of quantities is provided for one embodiment of the present application. DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0033] In one embodiment, Figure 1 As shown, a method for predicting project cash inflow based on human resources and machine resources under the bill of quantities payment method is provided, including the following steps:

[0034] Setting target resources, identifying and setting target resources with the largest amount from the bill of quantities;

[0035] Calculate the monthly resource consumption cost ratio, and calculate the ratio of the monthly cost of each target resource to its total cost based on the consumption of each target resource;

[0036] Calculate the monthly capital inflow by multiplying the comprehensive price of each bill of quantities by the monthly cost ratio of the target resource of each bill of quantities to obtain the monthly capital inflow of the bill of quantities;

[0037] Sum up the monthly cash inflows of all bills of quantities to get the total cash inflow per month;

[0038] Calculate the monthly inflow ratio, compare the total monthly capital inflow with the total project quotation, and get the monthly inflow ratio.

[0039] In this embodiment, the target resources include human resources, material resources and mechanical resources, wherein the resources are selected based on the resource with the highest amount in the project budget.

[0040] In this embodiment, the resource consumption ratio is calculated based on the consumption of each resource in the project, so as to ensure the accuracy of the cash inflow forecast.

[0041] It should be noted that the various resources and monthly consumption under the bill of quantities of this solution are known; mid-term payments are made according to the bill of quantities, rather than node payments or other methods. The cost management software calculates the cash flow allocation based on the target main resource with the largest amount under the bill of quantities.

[0042] In this embodiment, the capital inflow forecast adjusts the resource ratio according to different project stages. Specifically, the initial stage of the project focuses on material costs, and the middle and late stages focus on manpower and machinery costs, so as to accurately reflect the capital needs at different stages.

[0043] By summarizing the cash inflow of each bill of quantities on a monthly basis, the method provides a mechanism for generating a monthly cash flow forecast report to help project managers adjust funding arrangements and risk management strategies in a timely manner;

[0044] The method generates various forms of visual reports at different stages of each project, including monthly cash flow curves, resource consumption pie charts, and comparative analysis charts of capital inflow and resource utilization.

[0045] This embodiment proposes a comprehensive and accurate cash flow forecasting method by setting the main resources and calculating the capital inflow based on resource consumption. This method significantly improves the accuracy of cash flow forecasting and avoids the deviation caused by ignoring resource consumption in the traditional amortization method.

[0046] This embodiment defines human, material and machine resources as the main resources, thereby ensuring that the key resources with the highest proportion of the project amount are included in the forecast range, thereby further improving the accuracy of the capital inflow forecast and ensuring that the forecast results match the actual consumption.

[0047] This embodiment improves the flexibility and accuracy of capital inflow prediction by dynamically adjusting resource prices based on historical price data and market trends.

[0048] This embodiment enables the method to adapt to the needs of different stages of the project. By dynamically adjusting the consumption ratio of major resources, it can more accurately reflect the funding needs of different stages of the project, optimize funding management, and avoid the risk of excessive concentration or shortage of funds.

[0049] This embodiment provides a clear analysis of funds inflows for project managers by providing a monthly cash flow summary function, which helps to formulate a more reasonable fund arrangement plan, reduce uncertainty in fund management, and optimize overall fund allocation.

[0050] This embodiment generates visual reports in various forms, so that project managers can more intuitively understand the relationship between capital inflow and resource consumption, improve the transparency of project management, and facilitate better decision-making and adjustments.

[0051] By integrating with existing project management software, claim 8 simplifies the operation process, enables cash flow forecasting to be automatically executed, reduces the workload of manual input, reduces human operation errors, and improves the efficiency of project management.

[0052] This embodiment provides custom resource parameter settings so that the method can adapt to different types of engineering projects. Regardless of the size or complexity of the project, the method can be flexibly applied, thereby enhancing the applicability and practicality of the method.

[0053] In one embodiment, in traditional project cash flow management, the total revenue based on the bill of quantities is usually spread out to each month to roughly estimate the monthly cash inflow. However, this method ignores the actual consumption of resources, resulting in a large deviation between the cash flow forecast and the actual situation, which in turn affects the effective management of project funds and risk control. Therefore, how to more accurately predict project cash inflows and make them closer to the actual situation in the future has become a technical problem that needs to be solved in the current field of project management.

[0054] This embodiment proposes a method for predicting project cash inflow based on the main resources of manpower, materials and machines under the bill of quantities, aiming to solve the above problem. The method includes the following steps:

[0055] Set up major resources: Identify and set up major resources with the largest amount from the bill of quantities. These resources are usually the human, material and machine resources required for the project.

[0056] Calculate cost ratio: For each bill of quantities, calculate the ratio of the monthly cost of its main resources to its total cost. This step takes into account the actual consumption of resources and can more accurately reflect the utilization of resources.

[0057] Calculate monthly cash inflow: Multiply the total price of each bill of quantities by the cost ratio calculated in step 2 to get the monthly cash inflow for that bill of quantities.

[0058] Summarize the monthly total inflow: Summarize the monthly cash inflow of all bills of quantities on a monthly basis to obtain the monthly total inflow. This step can fully reflect the overall cash inflow of the project.

[0059] Calculate the cash inflow ratio: Compare the total monthly inflow with the total project quotation to obtain the monthly inflow ratio. This step helps project managers better understand the relationship between cash inflow and the total project price, so as to conduct more scientific fund management.

[0060] Through the technical solution of the present invention, project managers can predict cash inflows based on the actual consumption of major resources, making the prediction results more accurate and closer to future actual conditions.

[0061] The beneficial effects of this embodiment are mainly reflected in the following aspects:

[0062] Improve forecast accuracy: Through the forecasting method based on major resources, the present invention can more accurately reflect the cash inflow of the project and avoid the forecasting deviation caused by the traditional method due to ignoring the actual consumption of resources.

[0063] Optimize fund management: More accurate cash inflow forecasts help project managers formulate more reasonable fund plans, optimize fund allocation, and reduce fund risks.

[0064] Improve project management efficiency: The prediction method provided by the present invention is simple and easy to implement, can quickly obtain results, and improves the efficiency of project management.

[0065] In summary, the present invention solves the problem of inaccurate prediction in traditional methods by predicting project cash inflows based on the main resources of manpower, materials and machinery under the bill of quantities, and provides a more accurate and efficient cash flow prediction method for engineering project management.

[0066] Based on the income from the bill of quantities, spread out over each month, only a rough estimate can be achieved.

[0067] The technical problem to be solved by this embodiment is to provide a more accurate and sophisticated method for calculating the capital inflow of the bill of quantities, so as to overcome the defect of the prior art that only relies on the bill of quantities income to be spread out to each month for rough estimation. The existing method fails to fully consider the actual consumption of resources, resulting in a large deviation between the predicted results of cash inflow and the actual situation. This not only affects the effective management of project funds, but may also have an adverse impact on the progress and risk control of the project.

[0068] Therefore, this embodiment aims to provide a more accurate cash inflow calculation method by using the main resources of manpower, materials and machines under the bill of quantities (the largest amount) as the prediction basis. This method can comprehensively consider the actual consumption of resources, so as to more accurately predict the cash inflow of the project, making it closer to the actual situation in the future. This can not only improve the efficiency and accuracy of project fund management, but also help project managers to formulate more scientific and reasonable fund plans and risk control strategies, and provide strong guarantees for the smooth implementation and successful completion of the project.

[0069] Compared with the prior art, this embodiment has significant advantages and better effects in the calculation method of the capital inflow of the bill of quantities.

[0070] First, this embodiment uses the main resources of manpower, materials and machines under the bill of quantities (the largest amount) as the basis for predicting the cash inflow of the project, which can more accurately predict the cash inflow. Compared with the traditional method of only amortizing the income of the bill of quantities to make a rough estimate every month, the present invention comprehensively considers the actual consumption of resources, making the prediction result closer to the actual situation in the future.

[0071] Secondly, the forecasting method of this embodiment improves the efficiency and accuracy of project fund management. By accurately calculating the monthly fund inflow, project managers can formulate more scientific and reasonable fund plans, optimize fund allocation, and reduce fund risks. This helps the project proceed smoothly and reduces project delays or losses caused by fund problems.

[0072] In addition, this embodiment also helps to improve the decision-making level of project management. By comparing the total monthly inflow with the total project quotation, the project manager can clearly understand the relationship between cash inflow and the total project price, so as to make more informed decisions. For example, in the case of tight funds, resource allocation or procurement plans can be adjusted according to the cash inflow to ensure the smooth progress of the project.

[0073] In terms of specific experimental data, through application verification of actual projects, the method for calculating the capital inflow of the bill of quantities created by the present invention is superior to the traditional method in terms of accuracy and reliability. In many actual projects, the forecasting method created by the present invention can control the forecast error of cash inflow at a low level, providing strong support for project management.

[0074] In summary, this embodiment has better effects than the existing technology, can more accurately predict the project cash inflow, improve the efficiency and accuracy of project fund management, enhance the decision-making level of project management, and provide strong guarantees for the smooth implementation and successful completion of engineering projects.

[0075] In this embodiment, the daily demand for each budgeted machine is obtained through the data returned by P6, and the budgeted machines on the critical path are calculated first; the replacement calculation is performed based on the efficiency coefficient of the construction machinery converted into the budgeted machine, and the one with an efficiency conversion coefficient close to 1 is used first; if the absolute values ​​of the efficiency conversions of multiple construction machines that can be replaced by one budgeted machine are equal, the variable costs of the above-mentioned construction machines are compared, and the one with the lower cost is used first; follow the above steps to convert the budgeted machine into the construction machine.

[0076] In one embodiment, the total budget of a construction project is 10 million yuan, and the project period is 12 months. In the project budget, human resources account for 30%, material resources account for 50%, and mechanical resources account for 20%. The project is divided into three stages: initial stage (January to April), mid-term (May to August), and late stage (September to December).

[0077] According to this plan and budget, material resources account for the highest proportion, so material resources are set as target resources.

[0078] Calculate the monthly resource consumption cost ratio. Initial stage: material consumption is large, assuming that monthly consumption accounts for 10% of total material cost. Mid-term: human and mechanical resource consumption increases, assuming that monthly labor cost accounts for 8% of total labor cost, and mechanical cost accounts for 6% of total mechanical cost. Late stage: mainly human and mechanical resource consumption, assuming that monthly labor cost accounts for 10% of total labor cost, and mechanical cost accounts for 8% of total mechanical cost.

[0079] Calculate monthly capital inflow, initial stage: comprehensive price is 4 million, monthly capital inflow = 4 million * 10% = 400,000. Mid-term: comprehensive price is 3 million, monthly capital inflow = 3 million * (8% + 6%) = 420,000. Late stage: comprehensive price is 3 million, monthly capital inflow = 3 million * (10% + 8%) = 460,000.

[0080] Summarize the monthly cash inflows of all bills of quantities, and the total monthly cash inflow = initial monthly cash inflow + mid-term monthly cash inflow + late monthly cash inflow.

[0081] Calculate the monthly inflow ratio, monthly inflow ratio = total monthly capital inflow / total project quotation.

[0082] In the early stages of the project (January to April), focus on monitoring the consumption of material resources and capital inflow to ensure timely material supply and cost control.

[0083] In the middle of the project (May-August), as the project progresses, the investment in human resources increases, and it is necessary to monitor labor costs and machine utilization efficiency.

[0084] In the late stage of the project (September-December), the project is nearing completion and the focus is on completing the project and quality control while ensuring the rational allocation of funds.

[0085] Monthly cash flow curve: shows the monthly cash inflow and helps managers understand cash liquidity.

[0086] Resource consumption pie chart: displays the proportion of different resources in the total cost, and intuitively reflects the resource consumption situation.

[0087] Comparative analysis chart of capital inflow and resource utilization rate: Analyze the relationship between capital inflow and resource utilization efficiency to provide a basis for resource optimization.

[0088] Through this embodiment, project managers can more accurately predict and monitor the cash inflow of the project, and adjust funding arrangements and risk management strategies in a timely manner to ensure the smooth progress of the project.

[0096] In this embodiment, the resource consumption ratio is calculated based on the consumption of each resource in the project, so as to ensure the accuracy of the cash inflow forecast.
