Description

Technical Field

[0001] This invention relates to the field of fiberglass production scheduling technology, and in particular to a fiberglass production control method and system based on intelligent scheduling. Background Technology

[0002] Glass fiber (hereinafter referred to as "glass fiber"), as a high-performance inorganic non-metallic material, is widely used in many fields such as construction, transportation, electronics, and chemical industry due to its high strength, high temperature resistance, and corrosion resistance. Its production process typically involves multiple complex steps such as drawing, twisting, weaving, and post-processing, placing strict requirements on production equipment, process parameters, and personnel operation to ensure that the produced glass fiber products meet the diverse needs of different industries and customers in terms of quality and performance. However, in the actual production and operation of glass fiber companies, production scheduling is often flexibly arranged based on order volume. When the capacity of glass fiber production lines is excessive, in order to make full use of idle capacity and reduce production costs, companies often arbitrarily select production lines to put into production based on the current capacity status of the existing lines.

[0003] However, the traditional arbitrary arrangement method has significant drawbacks: due to differences in equipment aging, maintenance, and operating time among different production lines, those randomly selected for production are prone to potential equipment problems. These problems, if not detected and repaired in time, will significantly increase the probability of malfunctions during production. Once a production line malfunctions during production, it will not only directly lead to production interruption and affect the timely delivery of current orders, but also seriously impact the continuity and stability of the entire production process, thereby affecting the company's production efficiency and economic benefits.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the problem that, due to differences in equipment aging, maintenance, and operating time among different production lines, those randomly selected for production are prone to potential equipment problems. These undetected and unrepaired problems significantly increase the probability of malfunctions during production. Once a production line malfunctions, it not only directly leads to production interruption and affects the timely delivery of current orders, but also seriously impacts the continuity and stability of the entire production process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass fiber production control method based on intelligent scheduling, comprising the following steps: Step 1: Divide all fiberglass production lines within the production plant area and assign a unique number to each production line; Step 2: Obtain the preset capacity data for each production line, and at the same time obtain the current order volume. Analyze the operation of the production line based on the order volume and the production line capacity, and divide the capacity status of the fiberglass production lines in the factory into capacity saturation and capacity surplus states. Then generate an operation scheduling plan for the production line that meets the order volume. Step 3: Collect and analyze the operating data of production lines that are not scheduled for production in the operation scheduling plan to obtain the production line scheduling index for fiberglass production. The production line scheduling index is used to reflect the risk of failure in the operation scheduling plan. Step 4: Analyze the operation scheduling scheme based on the production line scheduling index, select the optimal operation scheduling scheme, and carry out inspection and maintenance on the fiberglass production lines that are not scheduled for production in the optimal operation scheduling scheme.

[0007] Furthermore, the process of analyzing the production line's operation based on order volume and production line capacity is as follows: S11. Obtain the preset capacity data for each production line, and simultaneously obtain and analyze the current order quantity; S12. Calculate the total capacity of all production lines according to the following formula. : ,in, This refers to the total number of all fiberglass production lines within the production plant area. For the first The pre-set capacity of the fiberglass production line; S13, Total capacity of all production lines With order volume Comparative analysis, when If this occurs, it means that the total capacity of all production lines cannot meet the order demand. The operation and scheduling plan is to increase capacity by adding production lines or installing high-efficiency production equipment to meet the order demand. S14, when When the total capacity of all production lines is just enough to meet the order demand, the capacity status of the fiberglass production lines in the factory is divided into the capacity saturation state, and all fiberglass production lines in the factory are running to produce fiberglass. The operation scheduling plan is that all production lines are put into production. S15, when If the total capacity of all production lines can meet the order demand and there is a surplus capacity, the capacity status of the fiberglass production lines in the factory area is classified as an overcapacity state. It is necessary to select some production lines from all production lines for fiberglass production, and at the same time, further analysis of the operation scheduling plan is required.

[0008] Furthermore, the process of generating an operation scheduling plan for the production line that meets the order volume is as follows: S21. Select the set of fiberglass production lines to operate in the factory area where there is overcapacity. ,gather The number of production lines in the middle is ,satisfy ,in, For the first The pre-set capacity of the fiberglass production line For order volume, and ,in, This represents the total number of all fiberglass production lines within the production plant area. S22, from Selected from the production lines within the production plant area Number of combinations of production lines : By traversing different The value generates all possible operation scheduling schemes that meet the order volume.

[0009] Furthermore, the calculation process for the production line scheduling index of fiberglass production is as follows: S31. Obtain and analyze the operation data of the production lines that are not scheduled for production in the operation scheduling plan. The operation data includes the failure rate, service life, and difference between the last maintenance date and the current date of the production line of the fiberglass production line that is not scheduled for production. S32. Calculate the production line scheduling index for glass fiber production according to the following formula. : in, This refers to the number of production equipment on fiberglass production lines that are not scheduled for production in factories with overcapacity. For the first The service life of the production equipment on the fiberglass production line that has not been assigned to production. For the preset first The standard service life of production equipment on a fiberglass production line that is not scheduled for production. For the first Failure rate of production equipment on fiberglass production lines that are not scheduled for production. For the preset first The standard failure rate of production equipment on a fiberglass production line that is not scheduled for production. This refers to the number of fiberglass production lines in a factory with overcapacity that are not currently scheduled for production. , For the fiberglass production line that was not scheduled for production, the first The difference between the most recent maintenance date and the current date for each production line. This is the preset standard maintenance frequency for the production line. The weighting coefficient is the preset service life. The higher the value of the production line scheduling index for fiberglass production, the lower the risk of failure in the corresponding operation scheduling scheme, and the more stable the entire fiberglass production process.

[0010] Furthermore, the process of determining the optimal operation scheduling scheme is as follows: through analysis and calculation, the production line scheduling index corresponding to all operation scheduling schemes is obtained. The production line scheduling indexes of each operation scheduling scheme are sorted according to their values. The operation scheduling scheme with the largest production line scheduling index is selected as the optimal operation scheduling scheme, and the fiberglass production work is carried out according to the optimal operation scheduling scheme.

[0011] The present invention also provides a glass fiber production control system based on intelligent scheduling, which is applied to a glass fiber production control method based on intelligent scheduling, including a production line division unit, a status analysis unit, a scheme generation unit, a scheduling analysis unit, and a scheme determination unit; The production line division unit is used to divide all fiberglass production lines in the production plant according to the complete production process and assign a unique number to each production line; The status analysis unit is used to obtain the preset capacity data of each production line, as well as the current order volume. Based on the order volume and production line capacity, it analyzes the operation of the production line and divides the capacity status of the fiberglass production line in the factory into capacity saturation and overcapacity. The scheme generation unit is used to generate an operation scheduling scheme for the production line that meets the order volume based on a comparative analysis of the total capacity of all production lines and the order volume. The scheduling analysis unit is used to collect the operating data of production lines that are not scheduled for production in the operation scheduling plan, and to analyze and calculate the production line scheduling index for fiberglass production. The production line scheduling index is used to reflect the risk of failure in the operation scheduling plan. The scheme determination unit is used to analyze the operation scheduling scheme based on the production line scheduling index, select the optimal operation scheduling scheme, and carry out inspection and maintenance on the fiberglass production lines that are not scheduled for production in the optimal operation scheduling scheme.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This intelligent scheduling-based fiberglass production control method and system divides all fiberglass production lines within the production plant area and assigns them unique numbers, achieving systematic identification and management of the production lines. This lays the foundation for precise scheduling, thus avoiding the uncertainty caused by arbitrary manual scheduling. Furthermore, by acquiring the preset capacity data and current order volume of each production line in real time, the system scientifically analyzes the production line's operating status and classifies the capacity status into saturated and overcapacity states. Based on this, multiple operation scheduling schemes that meet order demands are generated, ensuring efficient matching of capacity and orders and reducing resource waste and production delay risks. In addition, by collecting data... The system collects operational data from production lines not scheduled for production and calculates a production line scheduling index using a pre-defined formula. This quantitatively assesses the failure risk of each scheduling scheme, allowing the system to intuitively compare the stability of different schemes. Based on this, by selecting the scheme with the highest scheduling index as the optimal operation scheduling scheme, the probability of failures caused by factors such as equipment aging and insufficient maintenance is significantly reduced, thereby improving the continuity and stability of the production process and ensuring on-time order delivery. At the same time, timely inspection and maintenance are carried out on production lines not scheduled for production in the optimal scheme, realizing preventive maintenance, eliminating potential equipment problems in advance, extending equipment life, and reducing operation and maintenance costs.

Then, the preset capacity data of each production line is obtained, along with the current order volume. The operation of the production line is analyzed based on the order volume and the production line capacity. The capacity status of the fiberglass production lines in the factory is divided into capacity saturation and capacity surplus. Then, an operation scheduling plan for the production line that meets the order volume is generated. The process of analyzing the production line's operation based on order volume and production line capacity is as follows: S11. Obtain the preset capacity data for each production line, and simultaneously obtain and analyze the current order quantity; S12. Calculate the total capacity of all production lines according to the following formula. : ,in, This refers to the total number of all fiberglass production lines within the production plant area. For the first The pre-set capacity of the fiberglass production line; S13, Total capacity of all production lines With order volume Comparative analysis, when If this occurs, it means that the total capacity of all production lines cannot meet the order demand. The operation and scheduling plan is to increase capacity by adding production lines or installing high-efficiency production equipment to meet the order demand. S14, when When the total capacity of all production lines is just enough to meet the order demand, the capacity status of the fiberglass production lines in the factory is divided into the capacity saturation state, and all fiberglass production lines in the factory are running to produce fiberglass. The operation scheduling plan is that all production lines are put into production. S15, when If the total capacity of all production lines can meet the order demand and there is a surplus capacity, the capacity status of the fiberglass production lines in the factory area is classified as an overcapacity state. It is necessary to select some production lines from all production lines for fiberglass production, and at the same time, further analysis of the operation scheduling plan is required.

[0016] The process of generating an operation scheduling plan for the production line that meets the order volume is as follows: S21.

[0017] Next, the operation data of the production lines that were not scheduled for production in the operation scheduling plan were collected, analyzed and calculated to obtain the production line scheduling index for fiberglass production. The production line scheduling index is used to reflect the risk of failure in the operation scheduling plan. The calculation process for the production line scheduling index of fiberglass production is as follows: S31. Obtain and analyze the operation data of the production lines that are not scheduled for production in the operation scheduling plan. The operation data includes the failure rate, service life, and difference between the last maintenance date and the current date of the production line of the fiberglass production line that is not scheduled for production. S32. Calculate the production line scheduling index for glass fiber production according to the following formula. : in, This refers to the number of production equipment on fiberglass production lines that are not scheduled for production in factories with overcapacity.

This is the preset standard maintenance frequency for the production line. The weighting coefficient is the preset service life. The higher the value of the production line scheduling index for fiberglass production, the lower the risk of failure in the corresponding operation scheduling scheme, and the more stable the entire fiberglass production process.

[0018] Finally, the operation scheduling schemes are analyzed based on the production line scheduling index, the optimal operation scheduling scheme is selected, and the fiberglass production lines that are not scheduled for production in the optimal operation scheduling scheme are inspected and maintained. The process of determining the optimal operation scheduling scheme is as follows: through analysis and calculation, the production line scheduling index of glass fiber production corresponding to all operation scheduling schemes is obtained. The production line scheduling index of each operation scheduling scheme is sorted according to its value. The operation scheduling scheme with the largest production line scheduling index is selected as the optimal operation scheduling scheme, and glass fiber production is carried out according to the optimal operation scheduling scheme. Example

Furthermore, by acquiring the preset capacity data and current order volume of each production line in real time, the invention scientifically analyzes the production line's operating status, classifying capacity status into saturation and overcapacity states. Based on this, multiple operation scheduling schemes are generated to meet order demands, ensuring efficient matching of capacity and orders and reducing resource waste and production delay risks. In addition, by collecting operating data from production lines not scheduled for production and using preset formulas to calculate the production line scheduling index, the system quantitatively assesses the failure risk of each scheduling scheme, allowing for a direct comparison of the stability of different schemes. Based on this, by selecting the scheme with the highest scheduling index as the optimal operation scheduling scheme, the probability of failures caused by factors such as equipment aging and insufficient maintenance is significantly reduced, thereby improving the continuity and stability of the production process and ensuring timely order delivery.
