Description

Technical Field

[0001] The present invention relates to the technical field of project management of construction enterprises, and in particular to a circulation evaluation system and method for circulating materials between project departments within an enterprise. Background Art

[0002] As a very important construction resource in construction enterprises, turnover materials are important internal fixed assets of enterprises. They can be reused many times during the construction process and are materials that can basically maintain their original physical form and gradually transfer their value. Scientifically and reasonably formulating turnover material circulation plans has an important impact on project construction progress and cost control.

[0003] An analysis of the circulation scheme of traditional circulating materials between project departments within construction enterprises revealed the following pain points: the information sharing of idle resources within construction enterprises is not smooth. Currently, the idle circulating materials and demand information of each branch, subsidiary and project department are generally collected manually, which has problems such as incomplete information and low timeliness. It is unable to effectively support internal resource allocation, resulting in a large amount of external procurement and leasing, resulting in a high idle rate of self-owned circulating materials; it is difficult to collect external resource information. Currently, when each branch, subsidiary and project conducts external sourcing, it is often necessary for material personnel to communicate with suppliers to obtain resource information, which requires a lot of effort. It is impossible to quickly and comprehensively obtain external resource information; the matching of supply and demand relies on personal experience. The turnover material requirements proposed by the demand department have specific names and specifications. However, during the sourcing process, if market resources are scarce, it is necessary to rely on the experience of material personnel to purchase other specifications to meet the requirements. At this time, the experience of material personnel plays a decisive role in procurement efficiency; manually formulating circulation plans is time-consuming and labor-intensive. When formulating procurement plans, material personnel need to fully consider internal resources, procurement methods, procurement costs, time period costs, capital costs and other factors. It is very easy to have repeated purchases, material backlogs, and waste, which will increase engineering costs and cause unnecessary losses to the benefits of the company and projects.

When the selling price difference is a negative value, the smaller the selling price difference is, the higher the selling price weight of the turnover material in the project department is; when the selling price difference is a positive value, the larger the selling price difference is, the higher the selling price weight of the turnover material in the project department is;

[0017] The rental price weight of a turnover material in a project department is preset according to the rental price difference obtained by subtracting the average rental price of the turnover material from the rental price of the turnover material in a project department.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 This is a system block diagram of the present invention. DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by 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.

[0038] Example 1

[0039] refer to Figure 1 , a circulation evaluation system for circulating materials between project departments within an enterprise, including:

[0040] Data collection module, used to collect the address of each project department and the type of each turnover material;

[0041] The turnover material circulation evaluation model construction module is used to preset a circulation distance weight table according to the address of each project department, preset a circulation price weight table according to the type of each turnover material, and then establish a turnover material circulation evaluation model according to the address of each project department, the circulation distance weight table, and the circulation price weight table;

[0042] The turnover material circulation assessment module is used to input the address of the project department with the turnover material demand, the address of the project department with the turnover material, and the type of the material to be circulated into the turnover material circulation assessment model, to obtain the circulation score of the material to be circulated from each project department with the turnover material to the project department with the turnover material demand, to sort the circulation score, and to recommend the project department with the turnover material demand to receive the source project department of the turnover material according to the sorting result of the circulation score.

[0043] (1) The address of the project department includes the longitude and latitude of the project department. The straight-line distance between two project departments obtained by longitude and latitude can generally represent the relative distance between different project departments, eliminating the need to calculate the actual road. By judging the relative distance between different project departments, the transportation cost of turnover materials can be reduced.

[0044] Preset a circulation price according to the type of circulating materials, the circulation price includes a selling price and a rental price, the circulation price weight table includes a selling price weight table and a rental price weight table, the selling price weight table is preset according to the selling price, and the rental price weight table is preset according to the rental price;

[0045] The selling price of the circulating materials includes the average selling price of the circulating materials and the selling price of the circulating materials of each project department. The rental price of the circulating materials includes the average rental price of the circulating materials and the rental price of the circulating materials of each project department. The average selling price of the circulating materials is the sum of the selling prices of the circulating materials in each project department divided by the total number of project departments. The average rental price of the circulating materials is the sum of the rental prices of the circulating materials in each project department divided by the total number of project departments.

[0046] The circulation price is preset with corresponding specific values ​​according to different time periods;

[0047] The average selling price of the circulating materials and the selling price of the circulating materials of each project department are preset in the same period, and the average rental price of the circulating materials and the rental price of the circulating materials of each project department are preset in the same period.

[0048] Generally speaking, the selling and leasing prices of circulating materials are preset once a month or a quarter. In the same period, the average selling or average leasing price of circulating materials is correlated with the selling or leasing price of the circulating materials in each project department. The obtained circulation price is more accurate. By selecting the project department with lower circulation prices in each period, the cost of circulation prices can be effectively reduced.

[0049] (2) The specific method of presetting the selling price weight table and the rental price weight table is:

[0050] The selling price weight of a turnover material in a project department is preset according to the selling price difference obtained by subtracting the average selling price of the turnover material from the selling price of the turnover material in the project department. When the selling price difference is a negative value, the smaller the selling price difference is, the higher the selling price weight of the turnover material in the project department is; when the selling price difference is a positive value, the larger the selling price difference is, the higher the selling price weight of the turnover material in the project department is;

[0051] The rental price weight of a turnover material in a project department is preset according to the rental price difference obtained by subtracting the average rental price of the turnover material from the rental price of the turnover material in a project department. When the rental price difference is a negative value, the smaller the rental price difference is, the higher the rental price weight of the turnover material in the project department is; when the rental price difference is a positive value, the larger the rental price difference is, the higher the rental price weight of the turnover material in the project department is;

[0052] Traverse all circulating materials and all project departments, preset a selling price weight table according to the selling price weight of each circulating material in each project department, and preset a rental price weight table according to the rental price weight of each circulating material in each project department.

[0053] The specific method of presetting the flow distance weight table according to the address of each project department is:

[0054] Presetting a distance weight between a certain project department and another project department according to the distance between the addresses of the project department and another project department, the closer the distance is, the higher the distance weight between the project department and another project department is;

[0055] Traverse all project departments and preset a distance weight table based on the distance weight between each project department and other project departments.

[0056] This technical solution actually assigns weights to the distance and price between project departments, assigns different weights according to different distances and prices, and dynamically affects the final score, which can widen the score gap and be more conducive to decision makers' judgment.

[0057] (3) The formula of the turnover material circulation evaluation model is:

[0058]

[0059] in,

[0060]

[0061] Among them, α is the preset distance coefficient, N i,j is the square of the straight-line distance between project department i with a demand for turnover material n and project department j with the turnover material n, T j,1 is the longitude of the project section j with the turnover material n, C i,1 is the longitude of project department i with turnover material n demand, T j,2 is the latitude of project unit j with the turnover material n, C i,2 is the latitude of project department i with turnover material n demand, K i,j is the distance weight between project department i with demand for turnover material n and project department j with the turnover material n, Pn,j M is the selling price of turnover material n in project department j that has the turnover material n, n is the average selling price of turnover material n, L n,j is the selling price weight of turnover material n in project department j that has turnover material n, S n,i,j P′ is the turnover fraction when project department j with the turnover material n sells it to project department i with the turnover material n demand. i,j M′ is the rental price of circulating material n in project department j that has the circulating material n. n is the average rental price of turnover material n, L′ n,j is the rental price weight of turnover material n in project department j that has turnover material n, S′ n,i,j The turnover score when project department i with a demand for circulating material n rents the circulating material n from project department j;

[0062] The distance weight K between project department i with turnover material demand and project department j with the turnover material i,j By querying the preset distance weight table, the selling price weight L of turnover material n in project department j with turnover material n is obtained. n,j By querying the preset selling price weight table, the rental price weight L' of the turnover material n in the project department j with the turnover material n is obtained. n,j Obtained by querying the preset rental price weight table.

[0063] Whether the rental price difference is negative or the selling price difference is negative, it means that the rental or selling price of the circulating material in the project department is lower than the average rental or selling price. At this time, the larger the weight, the higher the circulation score. If the rental price difference or the selling price difference is positive, it means that the rental or selling price of the circulating material in the project department is higher than the average rental or selling price. At this time, the larger the weight, the lower the circulation score.

[0064] The closer the address of a project department is to another project department, the greater the square value N of the straight-line distance between project department i with a demand for turnover material n and project department j with the turnover material n. i,j The smaller, the The larger the distance weight K is, the i,j Since the distance between the two project departments is relatively close, the distance weight K i,j The larger the preset value is, the higher the final circulation score is. From a practical point of view, it can be explained that the closer the distance, the lower the freight.

[0065] (4) The turnover scores at the time of sale or purchase are sorted respectively. The decision maker determines the project department with turnover material demand to receive the source project department of the turnover material based on the sorting results of the turnover scores. The higher the turnover score, the more worthy it is for the source project department of the turnover material to receive it. This system makes recommendations based on the sorting results, giving the decision maker a basis for decision-making, ultimately reducing the cost of manual management. The resulting turnover plan can also reduce the internal operation and maintenance costs of the enterprise, which is more objective and accurate than the judgment made by others.

[0066] Example 2

Then, a circulation material circulation evaluation model is established based on the address of each project department, the circulation distance weight table, and the circulation price weight table;

[0070] The addresses of project departments with demand for circulating materials, the addresses of project departments with the circulating materials, and the types of materials to be circulated are input into the circulating material circulation evaluation model to obtain the circulation scores of the materials to be circulated from the project departments with the circulating materials to the project departments with demand for circulating materials, and the circulation scores are sorted. According to the sorting results of the circulation scores, it is recommended that the project departments with demand for circulating materials receive the source project departments of the circulating materials.

[0071] (1) The address of the project department includes the longitude and latitude of the project department. The straight-line distance between two project departments obtained by longitude and latitude can generally represent the relative distance between different project departments, eliminating the need to calculate the actual road. By judging the relative distance between different project departments, the transportation cost of turnover materials can be reduced.

[0072] Preset a circulation price according to the type of circulating materials, the circulation price includes a selling price and a rental price, the circulation price weight table includes a selling price weight table and a rental price weight table, the selling price weight table is preset according to the selling price, and the rental price weight table is preset according to the rental price;

[0073] The selling price of the circulating materials includes the average selling price of the circulating materials and the selling price of the circulating materials of each project department. The rental price of the circulating materials includes the average rental price of the circulating materials and the rental price of the circulating materials of each project department. The average selling price of the circulating materials is the sum of the selling prices of the circulating materials in each project department divided by the total number of project departments. The average rental price of the circulating materials is the sum of the rental prices of the circulating materials in each project department divided by the total number of project departments.

[0074] The circulation price is preset with corresponding specific values ​​according to different time periods;

[0075] The average selling price of the circulating materials and the selling price of the circulating materials of each project department are preset in the same period, and the average rental price of the circulating materials and the rental price of the circulating materials of each project department are preset in the same period.

[0076] Generally speaking, the selling and leasing prices of circulating materials are preset once a month or a quarter. In the same period, the average selling or average leasing price of circulating materials is correlated with the selling or leasing price of the circulating materials in each project department. The obtained circulation price is more accurate. By selecting the project department with lower circulation prices in each period, the cost of circulation prices can be effectively reduced.

[0077] (2) The specific method of presetting the selling price weight table and the rental price weight table is:

[0078] The selling price weight of a turnover material in a project department is preset according to the selling price difference obtained by subtracting the average selling price of the turnover material from the selling price of the turnover material in the project department. When the selling price difference is a negative value, the smaller the selling price difference is, the higher the selling price weight of the turnover material in the project department is; when the selling price difference is a positive value, the larger the selling price difference is, the higher the selling price weight of the turnover material in the project department is;

[0079] The rental price weight of a turnover material in a project department is preset according to the rental price difference obtained by subtracting the average rental price of the turnover material from the rental price of the turnover material in a project department. When the rental price difference is a negative value, the smaller the rental price difference is, the higher the rental price weight of the turnover material in the project department is; when the rental price difference is a positive value, the larger the rental price difference is, the higher the rental price weight of the turnover material in the project department is;

[0080] Traverse all circulating materials and all project departments, preset a selling price weight table according to the selling price weight of each circulating material in each project department, and preset a rental price weight table according to the rental price weight of each circulating material in each project department.

[0081] The specific method of presetting the flow distance weight table according to the address of each project department is:

[0082] Presetting a distance weight between a certain project department and another project department according to the distance between the addresses of the project department and another project department, the closer the distance is, the higher the distance weight between the project department and another project department is;

[0083] Traverse all project departments and preset a distance weight table based on the distance weight between each project department and other project departments.

[0084] This technical solution actually assigns weights to the distance and price between project departments, assigns different weights according to different distances and prices, and dynamically affects the final score, which can widen the score gap and be more conducive to decision makers' judgment.

[0085] (3) The formula of the turnover material circulation evaluation model is:

[0086]

[0087] in,

[0088]

[0089] Among them, α is the preset distance coefficient, N i,j is the square of the straight-line distance between project department i with a demand for turnover material n and project department j with the turnover material n, T j,1 is the longitude of the project section j with the turnover material n, C i,1 is the longitude of project department i with turnover material n demand, T j,2 is the latitude of project unit j with the turnover material n, C i,2 is the latitude of project department i with turnover material n demand, K i,j is the distance weight between project department i with demand for turnover material n and project department j with the turnover material n, P n,j M is the selling price of turnover material n in project department j that has the turnover material n, n is the average selling price of turnover material n, L n,j is the selling price weight of turnover material n in project department j that has turnover material n, S n,i,j P′ is the turnover fraction when project department j with the turnover material n sells it to project department i with the turnover material n demand. i,j M′ is the rental price of circulating material n in project department j that has the circulating material n. n is the average rental price of turnover material n, L′ n,j is the rental price weight of turnover material n in project department j that has turnover material n, S′n,i,j The turnover score when project department i with a demand for circulating material n rents the circulating material n from project department j;

[0091] Whether the rental price difference is negative or the selling price difference is negative, it means that the rental or selling price of the circulating material in the project department is lower than the average rental or selling price. At this time, the larger the weight, the higher the circulation score. If the rental price difference or the selling price difference is positive, it means that the rental or selling price of the circulating material in the project department is higher than the average rental or selling price. At this time, the larger the weight, the lower the circulation score.

[0092] The closer the address of a project department is to another project department, the greater the square value N of the straight-line distance between project department i with a demand for turnover material n and project department j with the turnover material n. i,j The smaller, the The larger the distance weight K is, the i,j Since the distance between the two project departments is relatively close, the distance weight K i,j The larger the preset value is, the higher the final circulation score is. From a practical point of view, it can be explained that the closer the distance, the lower the freight.
