The material demand information refers to the material to be purchased in the current project and includes the type, model and quantity of the material, and the historical order information is the material information purchased in the history and includes a supplier code, a historical supply time, a historical supply price and the like.
And S200, calculating and judging whether the project progress has delay or not according to the basic information of the project progress, and calculating the expiration time.
In this step, whether or not there is a delay in the project progress is calculated and determined based on the basic information of the project progress. The actual progress of the current project is recorded in the basic information of the project progress, and the daily progress amount is arranged in the total progress plan, so that the actual progress can be counted every day, the actual progress is compared with the plan progress, whether the current project progress has delay or not is determined, and the corresponding expiry time is calculated. The term "time out" refers to the time length that the original scheduled time will be exceeded according to the current project schedule. For example, if the project is planned to be completed in 10 days and the project is completed in 11 days according to the actual schedule, the expiration time is 1 day, and if there is no delay, the expiration time is 0 or a negative number.
S300, historical order information is inquired, the supply period and the material price of each provider are calculated, and the material cost corresponding to supply of each provider is calculated.
In this step, the historical order information is queried, and in the historical order, the time consumed by each supplier in the supply process is recorded, for example, in the supply process of the supplier A, the supply quantity is
Figure 873056DEST_PATH_IMAGE024
The supply time is
Figure 842149DEST_PATH_IMAGE025
In another supply process, the supply quantity is

In the step, the overdue penalties corresponding to the material supply of each provider are calculated, the time required for completing the current project is calculated according to the current project schedule, the influence of the material supply periods corresponding to different providers on the project completion time is determined, the overdue penalties to be generated are calculated according to the overdue time, the total costs corresponding to the different providers are obtained, the provider corresponding to the lowest total cost is selected, and the purchase order is generated.
As shown in fig. 2, as a preferred embodiment of the present invention, the step of calculating and judging whether there is a delay in the project progress according to the project progress basic information and calculating the expiration time specifically includes:
s201, obtaining a progress plan, and determining a plan progress value corresponding to the current time.
In this step, a schedule is obtained, the time for implementing the project is determined according to the project starting time and the date corresponding to the current time, and then the task schedule which should be completed by the project at the current time is obtained through query. For example, for a ten day project, the project schedule on the fifth day should be 50%, i.e., the projected schedule value is 50%.
And S202, judging whether a delay exists according to the project progress proportion and the planning progress value in the project progress basic information.
In this step, a project progress ratio in the project progress basic information is called, the project progress ratio is a progress of actually completing the project, for example, the completion progress on the fifth day is 48%, and then the project progress ratio is compared with a planning progress value to determine whether there is a delay in the current project, the completion progress on the fifth day is 48%, and the planning progress value is 50%, which indicates the project delay.
S203, calculating the current average progress value, and calculating the time-out according to the average progress value.
In this step, the current average progress value is calculated, and if 48% of tasks are completed on the fifth day, it indicates that the daily progress of the current project is 9.6%, the time required for the remaining tasks is calculated according to the remaining task amount, that is, the time required for completing the remaining 50% of task amount is calculated with the daily progress of 9.6%, and the expiration time is determined.
As shown in fig. 3, as a preferred embodiment of the present invention, the steps of querying the historical order information, calculating a supply period and a material price of each provider, and calculating a material cost corresponding to supply of each provider specifically include:
s301, historical order information is inquired, and the average supply time of the provider is calculated to obtain the supply period.
In this step, historical order information is queried, historical order information corresponding to one supplier is queried each time, and the relationship between the quantity corresponding to each material and the supply time is queried, so that the supply cycle of different quantities of goods corresponding to each material of each supplier is determined.
In this step, theiA supplier suppliesjThe calculation formula of the supply period corresponding to the seed material is expressed as follows:

as shown in fig. 4, as a preferred embodiment of the present invention, the steps of calculating overdue penalties corresponding to goods suppliers of various providers, calculating corresponding total costs, selecting a provider corresponding to the lowest total cost, and generating a purchase order specifically include:
s401, determining corresponding overdue time according to the supply period corresponding to each supplier.
In this embodiment, since the prices of materials of the suppliers are different, the demander comprehensively considers the price of the material of each supplier when purchasing the material, and comprehensively sets the waiting time corresponding to a certain material for each supplier. Specifically, the formula for determining the corresponding expiration time according to the supply period corresponding to each provider is as follows:
Figure 635661DEST_PATH_IMAGE013
wherein the content of the first and second substances,

Figure 569485DEST_PATH_IMAGE015
Is greater than that ofiA supplier suppliesjSupply period corresponding to the material
Figure 812248DEST_PATH_IMAGE002
If so, the overdue time is 0, otherwise, the overdue time is the absolute value of the difference between the two. And S402, determining the corresponding overdue penalty according to a preset overdue penalty calculation formula.
In the step, according to a preset overdue penalty calculation formula, when a project is agreed in a project contract and is delayed, the overdue penalty is calculated in a mode, so that the overdue penalty can be directly determined, and different suppliers can have different supply periods, and different overdue penalties can be caused.
It should be noted that, when purchasing, the demand side often considers two factors, namely price and supply period. If the supplier is considered to be less expensive by the demander and the demander allows for overdue offerings within acceptable limits, a combination of two factors is often considered. On the contrary, some suppliers with strong timeliness do not have overdue, but the unit price of the given materials is often higher, and the demand side is not necessarily favored.
In this embodiment, the demander purchasesiOf a supplierjThe formula of overdue penalty corresponding to the seed material is shown as follows:

It will be appreciated that in this embodiment, the total number of suppliers isMThe demanders can pass the comparisonMAnd finally determining a proper purchasing scheme according to the level of the total purchasing cost corresponding to any one of the suppliers, and further generating a purchasing order.
In the step, the total cost is calculated according to the overdue penalty and the material costs corresponding to each supplier, the overdue penalty and the material costs are superposed to obtain the total cost, then the total cost corresponding to the supply of goods by adopting different suppliers is compared, and one supplier with the lowest total cost is selected, because the supply periods of the different suppliers are different, the given prices of the different suppliers have corresponding differences, for example, the supply period of the supplier A is 10 days, the price is B, the supply period of the supplier A is 5 days, and the price is 1.5B, so that the supply period is long, the project is overdue, but the total cost is reduced, and the project cost can be ensured to be lower by comparison; the purchase order comprises the material quantity and the latest supply time; and if the total overdue time exceeds the preset value, determining the supplier with the lowest cost by taking the total overdue time as a limit.
