Specifically, the early warning rules for the low signing rate of material purchase orders in the risk management and control indicators of the material procurement stage are as follows: when the actual start time of the distribution network infrastructure project exceeds 3 months, and the proportion of material purchase orders is less than 10%, it will be regarded as a material purchase order. The purchase order signing rate is too low, and an early warning is issued.

Specifically, the early warning rules for whether the material requisition amount in the risk management and control indicators of the material requisition stage exceeds the demand reporting indicator are: if the demand has not been reported and the material requisition has occurred, the requisition procedure is not in compliance and an early warning will be issued; If the demand has been reported and the amount of materials received is greater than the amount reported for the demand, it is not in compliance and an early warning will be issued. The early warning rules for whether the material requisition time matches the construction progress are as follows: the first material requisition time is 3 months after the start of the project, and if the material requisition time does not match the construction progress, an early warning will be issued. The early warning rules for whether the proportion of material requisition to the total investment in the feasibility study is too high are: if the proportion of material requisition is >70%, the proportion of material requisition is too high, and an early warning will be issued. The early warning rule for the rationality index of the last material requisition time is as follows: if the last material requisition date is before the distribution network infrastructure project commissioning date, it is normal; otherwise, the material requisition is abnormal, and an early warning is given. The early warning rules for the abnormal indicators of the main material consumption scale of the project put into operation are as follows: after the project is put into production, if the construction scale is within the scale approved by the feasibility study, it is considered normal; otherwise, it is abnormal and an early warning is issued.

Specifically, the early warning rules for the high ratio of material withdrawals in the risk management and control indicators of the material withdrawal stage are as follows: when the rate of material withdrawals is ≤ 5%, the withdrawals are normal; otherwise, an early warning is issued.

The following is a specific example of a 10kV line renovation project in eastern Mongolia, China, in detail for the risk warning method for the entire process of material management of distribution network infrastructure projects according to the present invention:

The basic situation of the distribution network infrastructure project is as follows: the start date of the distribution network infrastructure project is March 30, 2020, the total investment in the feasibility study is 1.3214 million yuan, the length of the feasibility study approved line is 7.31 kilometers, and the amount of demand submitted is 222,600 yuan. The total amount of materials received was 1.8368 million yuan, the total amount of materials returned was 809,200 yuan, and the net amount of materials received was 1.0276 million yuan.

According to the method of the present invention, each stage of material management of the distribution network infrastructure project is processed, and the early warning situation of each stage of material management of the distribution network infrastructure project is shown in FIG. 1 .

Whether the amount of material picking exceeds the demand report indicator warning:

As of the end of June, the net amount of material requisition exceeded the demand and reported an amount of 805,000 yuan, so whether the material requisition amount exceeds the demand indicator is an early warning. Reason analysis: In accordance with the principle of "beneficiary first, then purchase", combined with the work of inventory materials, when the project was just started, some existing inventory materials were out of the warehouse, resulting in the amount of materials used exceeding the demand and reported.

Whether the proportion of material picking amount to the total investment in the feasibility study is too high indicator warning:

The net amount of material requisition accounts for 78% of the total investment in the feasibility study, which exceeds the early warning standard of 70%. Therefore, the matching indicator between the material requisition time and the construction progress is an early warning. Reason analysis: The distribution network infrastructure project failed to fully consider the actual situation of the distribution network infrastructure project when the materials were extracted, and the matching operation was wrong, and the materials from other projects were matched to the distribution network infrastructure project. As of the end of June, 809,200 yuan of materials had been withdrawn from the warehouse, and another 688,400 yuan had been withdrawn from the warehouse in July, leaving 339,200 yuan of materials used in the project.

Early warning of high ratio of materials returned from storage:

The proportion of project materials returned is 44%, and the proportion of returned materials is too high, so the indicator for the high proportion of materials returned to warehouse is an early warning. Reason analysis: The distribution network infrastructure project failed to fully consider the actual situation of the distribution network infrastructure project when the materials were extracted, and the matching operation was wrong, and the materials from other projects were matched to the distribution network infrastructure project, so the proportion of withdrawals was too high.
