[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] See also Figure 1 The present invention provides a technical solution: a method for controlling the construction costs of a tobacco station project, comprising the following steps: S1. Using a cost analysis method to conduct a detailed analysis of the various costs of the tobacco station project, and determine the cost structure and its influencing factors; S2. Using a deviation analysis method to compare the actual cost with the budgeted cost, identify the cost deviation and analyze its cause; S3. Formulate a target cost method, set a reasonable cost control target, and control the cost by decomposing the target cost into each construction link; S4. Implement a responsibility cost method, clarify the person responsible for each construction link, and establish a cost control responsibility system.

[0052] The cost analysis method in step S1 includes the following steps:

Classify and organize the collected cost data to form a cost structure table; S13. Analyze the influencing factors of each cost structure and determine the main cost driving factors; S14. Develop a cost control strategy based on the analysis results; S15. Use historical cost data to establish a cost forecasting model to predict future cost change trends; S16. Based on the forecast results, develop a cost control plan in advance to prevent the risk of cost overruns.

[0054] It should be noted that the various cost data of the tobacco station project should be collected, including: material costs (such as steel bars, cement, wood, etc.); labor costs (such as workers' wages, management staff salaries, etc.); machinery costs (such as equipment rental fees, maintenance fees, etc.); management costs (such as office expenses, travel expenses, etc.), to ensure that the data source is accurate and comprehensive, and provide a basis for subsequent analysis; in the classification and collation of cost data, the cost structure table usually includes: cost items (such as materials, labor, machinery, management, etc.); cost amount; cost proportion (the proportion of each cost item in the total cost); analysis of the influencing factors of each cost structure, for example: material cost: affected by market price fluctuations, procurement volume, transportation costs, etc.; labor cost: affected by the number of workers, wage level, work efficiency, etc.; machinery cost: affected by equipment rental price, frequency of use, maintenance costs, etc.; management cost: affected by the number of management personnel, office expenses, travel frequency, etc.; formulate targeted cost control strategies based on the analysis results of cost structure and its influencing factors. For example: Material cost control: Optimize the procurement process and select suppliers with high cost-effectiveness; Labor cost control: Improve worker efficiency and arrange working hours reasonably; Machinery cost control: Optimize equipment usage plan and reduce idle time; Management cost control: Streamline management personnel and reduce office expenses;

[0055] When calculating the cost ratio, according to the formula:

[0056]

[0057] R 成本占比 : the proportion of a certain cost to the total cost; C 单向成本 : The amount of a certain cost; C 总成本 : total cost amount;

[0058] When analyzing cost drivers, correlation analysis or regression analysis is used to determine the degree of impact of each factor on cost. The formula is:

[0059] C 材料 =a×P 材料 +b×Q 材料 +c×T 运输 ,

[0060] Among them, C 材料 represents the material cost; P 材料 Indicates the unit price of materials; Q 材料 Indicates the quantity of material; T 运输 represents transportation cost; a, b, c represent regression coefficients;

[0061] In the cost prediction model (taking linear regression as an example):

[0062] C 预测 =a0+a1×X1+a2×X2+...+a n ×X n ,

[0063] Among them, C 预测 represents the prediction cost; X1, X2, ..., X n Indicates factors that affect cost (such as material price, labor quantity, etc.); a0, a1, ..., a n represents the regression coefficient;

[0064] Cost deviation prediction:

[0065] ΔC 预测 =C 预测 -C 预算 ,

[0066] Where, ΔC 预测 represents the forecast cost deviation; C 预测 represents the prediction cost; C 预算 represents the budgeted cost;

[0067] Cost control target setting:

[0068] C 目标 =C 预算 ×(1-R 控制比例 ),

[0069] Among them, C 目标 Represents the cost control target; R 控制比例 Indicates the cost control ratio (e.g. 5% means a 5% cost reduction).

[0070] The deviation analysis method in step S2 includes the following steps:

[0071] S21. Regularly collect actual cost data and compare it with the budgeted cost; S22. Calculate cost deviations and identify cost items with large deviations; S23. Analyze the causes of deviations, including material price fluctuations, construction schedule delays, and design changes; S24. Based on the deviation analysis results, take appropriate corrective measures and adjust cost control strategies; S25. Utilize information technology to monitor cost data in real time and promptly identify cost deviations; S26. Establish a cost deviation early warning mechanism to automatically trigger an early warning signal when the deviation exceeds the preset threshold.

[0072] It should be noted that the actual cost data of materials, including material cost, labor cost, machinery cost, management cost, etc., is collected to ensure that the data source is accurate and comprehensive, providing a reliable basis for subsequent analysis. The actual cost data is compared with the budgeted cost to identify whether there is a deviation. The comparison content includes the actual value and budget value of each cost item, calculates the deviation value of the cost item, and identifies the cost item with large deviation. The deviation calculation formula is:

[0073] ΔC=C 实际 -C 预算 ,

[0074] Among them, ΔC represents the cost deviation; C 实际 Indicates actual cost; C 预算 represents the budgeted cost;

[0075] Conduct in-depth analysis of cost items with large deviations to determine the causes of the deviations, which may include: material price fluctuations, construction schedule delays, design changes, and other uncontrollable factors (such as weather and policy changes). Based on the deviation analysis results, formulate and implement corresponding corrective measures. Collect and monitor cost data in real time through information systems (such as ERP, project management software, etc.); set a preset threshold for cost deviation (such as ±5%). When the deviation exceeds the threshold, an early warning signal is automatically triggered. The early warning mechanism formula is:

[0076]

[0077] Among them, R 阈值 Indicates the preset deviation threshold;

[0078] When calculating the deviation rate:

[0079]

[0080] Among them, R 偏差 represents the cost deviation rate; ΔC represents the cost deviation; C 预算 represents the budgeted cost;

[0081] When calculating the cumulative deviation:

[0082]

[0083] Where, ΔC 累计 represents the cumulative cost deviation; C 实际，i represents the actual cost of period u; C 预算，i represents the budget cost for period i.

[0084] The target cost method in step S3 includes the following steps:

[0085] S31. Set target costs for each construction phase based on the overall budget of the tobacco station project. S32. Decompose the target costs into each construction link and clarify the cost control targets for each link. S33. Develop a detailed cost control plan, including material procurement plan, construction schedule plan, and quality control plan. S34. Regularly check the implementation of target costs and adjust control measures in a timely manner. S35. Utilize the principles of value engineering to optimize design solutions and reduce target costs. S36. Select cost-effective materials and equipment through bidding and procurement to further control target costs.

[0086] It should be noted that when setting the target cost for each construction stage, the target cost is usually set based on the overall budget and the division of construction stages. The formula is:

[0087] C 目标 =C 总预算 ×R 阶段比例 ,

[0088] Among them, C 目标 Indicates the target cost of a construction phase; C 总预算 represents the total budget of the tobacco station project; R 阶段比例 Indicates the proportion of this construction phase in the total budget (determined based on the project volume and construction difficulty);

[0089] When the target cost is broken down into each construction link, the formula is used:

[0090] C 环节 =C 目标 ×R 环节比例 ,

[0091] Among them, C 环节 Indicates the target cost of a construction link; R 环节比例 Indicates the cost proportion of this link in the construction phase (determined based on the project volume, material usage, labor requirements, etc.);

[0092] When formulating material procurement plans, construction schedules, and quality control plans, material procurement cost control:

[0093]

[0094] Among them, C 材料Indicates the total cost of material procurement; Q i represents the purchase quantity of the i-th material; P i represents the unit price of the i-th material;

[0095] Construction progress cost control:

[0096]

[0097] Among them, C 进度 Indicates the cost adjusted according to the actual progress; T 实际 Indicates the actual construction time; T 计划 Indicates the planned construction time;

[0098] C 质量 =C 目标 ×(1-R 返工率 ),

[0099] Among them, C 质量 represents the cost after quality control is considered; R 返工率 Represents the rework rate (the proportion of rework cost to total cost);

[0100] When checking the target cost implementation, the cost deviation can be calculated using the following formula:

[0101] ΔC=C 实际 -C 目标 ,

[0102] Among them, ΔC represents the cost deviation; C 实际 Indicates the actual cost incurred; C 目标 It represents the target cost. If the deviation exceeds a preset threshold (e.g. ±5%), the control measures need to be adjusted.

[0103] The core of value engineering is to improve the ratio of function to cost. The formula is:

[0104]

[0105] Among them, V represents value; F represents function (such as construction quality, performance, etc.); C represents cost. By optimizing the design scheme, the V value can be improved, that is, the cost can be reduced while ensuring the function.

[0106] In tendering and procurement, when evaluating the cost-effectiveness:

[0107]

[0108] Among them, R 性价比 Indicates price / performance ratio; Q 质量 Indicates the quality rating of materials or equipment (such as durability, performance, etc.); P 价格Indicates the purchase price of materials or equipment, selects the most cost-effective materials and equipment, and further controls the target cost.

[0109] The responsibility cost method in step S4 includes the following steps:

[0110] S41. Identify the responsible persons for each construction link, including project managers, construction team leaders, and material purchasers; S42. Establish a cost control responsibility system, and link cost control targets with the performance appraisals of responsible persons; S43. Hold cost control meetings regularly to report on the cost control status of each responsible person; S44. Provide rewards and punishments based on the cost control performance of the responsible person; S45. Establish a cost control information system to record the cost control data of each responsible person in real time; S46. Use big data analysis technology to evaluate the cost control effectiveness of the responsible person and optimize the distribution of responsibilities.

[0111] It should be noted that the project manager is responsible for overall project cost control; the construction team leader is responsible for cost control of specific construction links; and the material purchaser is responsible for cost control of the material procurement link. Ensure that each link has a clear person in charge to avoid unclear responsibilities. Cost control targets are broken down to each person in charge and linked to their performance appraisal. Clear appraisal indicators are established, such as cost deviation rate, cost savings amount, and implementation of cost control measures.

[0112] Cost deviation rate calculation:

[0113]

[0114] Among them, R 偏差 represents the cost deviation rate; C 实际 Indicates actual cost; C 目标 represents the target cost;

[0115] Calculation of cost savings:

[0116] ΔC 节约 =C 预算 -C 实际 ,

[0117] Where, ΔC 节约 Indicates the amount of cost savings; C 预算 represents the budget cost; C 实际 Indicates actual cost;

[0118] Responsible person's performance appraisal score:

[0119] S 绩效 =ω1×R 偏差 +ω2×ΔC 节约 +ω3×Q 措施 ,

[0120] Among them, S绩效 Represents the performance evaluation score of the responsible person; R 偏差 Indicates the cost deviation rate; ΔC 节约 Indicates the amount of cost savings; Q 措施 represents the execution quality score of cost control measures; ω1, ω2, ω3 represent weight coefficients (set according to actual conditions);

[0121] Calculation of reward and punishment amount:

[0122] B 奖惩 =S 绩效 ×K 奖惩系数 ,

[0123] Among them, B 奖惩 Indicates the amount of reward or punishment; S 绩效 Indicates the performance evaluation score of the responsible person; K 奖惩系数 Indicates the reward and punishment coefficient (set according to company policy);

[0124] Using big data analysis technology, we can establish a responsibility allocation optimization model, such as:

[0125]

[0126] Among them, C 实际，i represents the actual cost of the i-th responsible person; C 目标，i Represents the target cost of the i-th responsible person.

[0127] In summary, the present invention, through the comprehensive application of cost analysis, deviation analysis, target costing and responsibility costing, can significantly improve the accuracy and efficiency of cost control, reduce construction costs, enhance project economic benefits and management level, while preventing the risk of cost overruns, optimizing resource allocation, and promoting project quality and sustainable development.
