Description

Technical Field

[0001] The present invention relates to the technical field of intelligent optimization of production scheduling, and in particular to an intelligent optimization method for production scheduling of a production process of a process industrial enterprise. Background Art

[0002] With the improvement of people's living standards, the demand for handicrafts is increasing. Process industry refers to the production industry that carries out processes through physical changes and chemical changes. The production process is complex, the division of labor among employees is complex, the production continuity is strong, and the risk is high. If problems occur locally, it will often affect the production process of the entire industrial enterprise. Scheduling can increase production capacity, reduce costs, increase production efficiency, and reduce production risks. Therefore, intelligent optimization of production scheduling is becoming increasingly important.

[0003] Currently, most employee scheduling is done through manual analysis, and the allocation method of staff is obtained through experience. The analysis of the actual work efficiency of each staff member is one-sided, and it is impossible to accurately allocate each staff member to each work section, which affects the collaborative relationship between each work section, reduces production efficiency, and causes one-sided employee scheduling results. At the same time, when employee production problems arise, scheduling cannot be carried out quickly, affecting production capacity and causing a lag in employee scheduling results.

[0004] Currently, most raw material scheduling is done through manual analysis, and the supply of raw materials is obtained through experience. It is unable to balance the relationship between the raw material demand of some processing sections and the excessive raw material supply of some processing sections, resulting in a waste of staff production efficiency, increased transportation and storage costs of raw materials, and increased production risks. Summary of the invention

According to the current production rate of each section and the preset production rate, obtain each production transfer section. According to the current production rate of each employee in each production transfer section, obtain each employee who can be transferred. Step 4: Employee production scheduling: Obtain the historical production data of each production transfer section of each employee who has been transferred out of production from the database and schedule the employees; Step 5: Usage data collection: collect raw material usage data; Step 6: Usage data analysis: Analyze the raw material usage data to obtain the current usage rate of each section, and then obtain the raw material usage rate of each section. According to the current usage rate of each section and the preset usage rate of the raw materials, each section is divided into a section where each raw material is transferred out, a section where each raw material is not dispatched, and a section where each raw material is transferred in; Step 7.

If the loss rate of the preset number of employees f in the transfer section c is less than the overflow rate of the production transfer section c, the number of employees that can be transferred from the transfer section c is f. If there are multiple numbers of employees that can be transferred from the transfer section c, the largest number is selected as the number of employees that can be transferred from the production transfer section c. According to the order of employees in each production transfer section, the employees before f in each production transfer section are recorded as transferable employees, and the production transfer employees are obtained by summarizing them.

If a preset acquisition rate of the first production transfer section is greater than or equal to the required rate, the number of employees to be transferred corresponding to the preset acquisition rate is recorded as the number of employees to be transferred into the first production transfer section. If the first production transfer section has multiple numbers of employees to be transferred, the number of employees to be transferred with the smallest preset acquisition rate is selected as the number of employees to be transferred into the first production transfer section.

[0013] All the employees transferred out of production except the employees who need to be transferred into the first production transfer section are recorded as the remaining employees after the first transfer, and the historical production rate of the second production transfer section of the remaining employees after the first transfer is substituted into the preset acquisition rate calculation formula The preset acquisition rate of each preset number of transferred employees in the second production transfer section is obtained. If a preset acquisition rate of the second production transfer section is greater than or equal to the required rate, the preset number of transferred employees corresponding to the preset acquisition rate is recorded as the required number of transferred employees in the second production transfer section. If the second production transfer section has multiple required numbers of transferred employees, the preset number of transferred employees with the smallest preset acquisition rate is selected as the required number of transferred employees in the second production transfer section, so as to obtain the preset number of transferred employees in each production transfer section.

[0014] The employees transferred from production are sorted in the order of the historical production rate of the first production transfer section, and the employees with the preset number of transferred employees are selected to be transferred from each production transfer section to the first production transfer section; the remaining production transferred employees from the first transfer are sorted in the order of the historical production rate of the second production transfer section, and the employees with the preset number of transferred employees are selected to be transferred from each production transfer section to the second production transfer section, so as to transfer the production transferred employees to each production transfer section.

[0028] Step 2: Production data collection: Collect employee production data.

[0029] In a specific embodiment, employee production data is collected. The specific collection process is as follows: according to the industrial product production process in the database, the assembly line is divided into various sections, and sensors are arranged at each employee's workstation in each section. After the employee produces the product, it will be sensed and recorded by the sensor. A preset time is set for collection, and the employee production data is collected from the sensor information, including the production quantity of employee B in the current section of section a for the preset time. , a is the number of each section, , , b is the employee number, , , the current production quantity of each employee in each section of the preset time is summarized to obtain the production quantity of each section of the preset time .

[0030] Step 3. Production data analysis: Analyze the production data of employees to obtain the current production rate of each section and the current production rate of each employee. According to the current production rate of each section and the preset production rate, obtain each production transfer section. According to the current production rate of each employee in each production transfer section, obtain each transferable employee.

[0031] In a specific embodiment, the production data of employees is analyzed, and the specific analysis process is as follows: the production quantity of the preset time section a is Substitute into the rate calculation formula The current production rate of section a is obtained , The preset duration.

[0032] If the current production rate of a section is greater than the preset production rate, it indicates that the section is a production transfer section. The production transfer sections are numbered in descending order of production rate to obtain the number c of each production transfer section. , , substitute the current production rate of each production transfer section into the calculation formula required for production In the above equation, the overflow rate of each production transfer section is obtained. If the current production rate of a section is equal to the preset production rate, it indicates that the section is a production section that does not need to be dispatched.

The production transfer sections are numbered in ascending order according to the current production rate to obtain the number d of each production transfer section. , , substitute the current production rate of each production section into the calculation formula required for production In the process, the required rate of each production transfer section is obtained.

[0033] The employees in each production section are numbered in descending order according to their current production rate, numbered as e. , , substitute the current production rate of each employee in each production transfer section into the loss rate calculation formula In the above equation, the loss rate of the preset number of employees f in the transfer section c is obtained. If the loss rate of the preset number of employees f in the transfer section c is less than the overflow rate of the production transfer section c, the number of employees that can be transferred from the transfer section c is f. If there are multiple numbers of employees that can be transferred from the transfer section c, the largest number is selected as the number of employees that can be transferred from the production transfer section c. According to the order of employees in each production transfer section, the employees before f in each production transfer section are recorded as transferable employees, and the production transfer employees are obtained by summarizing them.

[0034] It should be supplemented that, by calculating the loss rate, we can obtain the impact of each employee's transfer on each production transfer section. By setting the upper limit of the loss rate as the overflow rate of each section, more employees can be selected for transfer while meeting the basic production needs of each production transfer section.

[0035] Step 4: Employee production scheduling: obtain the historical production data of each production transfer section of each employee who is transferred out of production from the database and schedule the employees.

[0036] In a specific embodiment, the employees are scheduled, and the specific scheduling process is as follows: the historical production rate of each production section of each transferred employee is obtained from the database, and each transferred employee is numbered in order of historical production rate from small to large, and the number is g. , , according to the current production rate of each production transfer section from small to large, substitute the historical production rate of each transferred employee in the first production transfer section into the preset acquisition rate calculation formula The preset acquisition rate of the number of employees to be transferred into the first production transfer section is obtained. If a preset acquisition rate of the first production transfer section is greater than or equal to the required rate, the number of employees to be transferred corresponding to the preset acquisition rate is recorded as the number of employees to be transferred into the first production transfer section. If the first production transfer section has multiple numbers of employees to be transferred, the number of employees to be transferred with the smallest preset acquisition rate is selected as the number of employees to be transferred into the first production transfer section.

[0037] All transferred employees except those who need to be transferred into the first production transfer section are recorded as the remaining employees after the first transfer, and the historical production rate of the second production transfer section of the remaining employees after the first transfer is substituted into the preset acquisition rate calculation formula The preset acquisition rate of each preset number of transferred employees in the second production transfer section is obtained. If a preset acquisition rate of the second production transfer section is greater than or equal to the required rate, the preset number of transferred employees corresponding to the preset acquisition rate is recorded as the required number of transferred employees in the second production transfer section. If the second production transfer section has multiple required numbers of transferred employees, the preset number of transferred employees with the smallest preset acquisition rate is selected as the required number of transferred employees in the second production transfer section, so as to obtain the preset number of transferred employees in each production transfer section.

[0038] Sort the transferred employees in the order of the historical production rate of the first production transfer-in section, select the employees with the preset number of transferred-in employees and transfer them from each production transfer-out section to the first production transfer-in section, sort the remaining transferred employees from the first transfer in the order of the historical production rate of the second production transfer-in section, select the employees with the preset number of transferred-in employees and transfer them from each production transfer-out section to the second production transfer-in section, so as to transfer the transferred employees to each production transfer-in section.

[0039] Step 5: Usage data collection: Collect raw material usage data.

[0040] In a specific embodiment, the raw material usage data is collected, and the specific collection process is as follows: a sensor is arranged at the feed port of each section to collect the raw material usage quantity of each section in each preset purchase cycle in the past, and the average value is calculated to obtain the average raw material usage quantity of each section in the preset purchase cycle. , a is the number of each section, , .

[0041] Step 6. Usage data analysis: Analyze the raw material usage data to obtain the current usage rate of each section, and then obtain the raw material usage rate of each section. According to the current usage rate of each section and the preset raw material usage rate, each section is divided into a raw material transfer section, a raw material non-dispatching section, and a raw material transfer section.

[0042] In a specific embodiment, the raw material usage data is analyzed, and the specific analysis process is as follows: Substitute the usage quantity of each stage of the preset purchase cycle into the rate calculation formula The current usage rate of each raw material section is obtained , The preset purchase cycle duration is used to substitute the raw material usage quantity of each raw material section and the preset raw material usage rate into the raw material usage rate calculation formula. The raw material utilization rate of each process section is obtained , Preset usage rates for ingredients.

[0043] It should be added that , M is the quantity of raw materials that the warehouse can hold.

[0044] If the current usage rate of a section is less than the preset raw material usage rate, the section is recorded as a raw material transfer section, and each raw material transfer section is numbered in order of raw material usage rate from small to large to obtain the number i of each raw material transfer section. , , substitute the current usage rate of each raw material transfer section into the material calculation formula The available share of raw material transfer section w in the purchase cycle is obtained , and the total share of the raw materials that can be adjusted is obtained by summarizing If the current usage rate of a section is equal to the preset usage rate of the raw material, the section is recorded as a section without raw material scheduling. If the current usage rate of a section is greater than the preset usage rate of the raw material, the section is recorded as a section for raw material transfer. The sections for raw material transfer are numbered in descending order according to the raw material usage rate to obtain the number j of each section for raw material transfer. , , substitute the current usage rate of each raw material transfer section into the material calculation formula The required transfer share of raw material transfer section w in the purchase cycle is obtained , summarize the total amount of raw materials that need to be transferred in .

[0045] Step 7. Raw material usage scheduling: Schedule the raw materials according to the raw material usage rate of each work section.

[0046] In a specific embodiment, the raw materials are scheduled, and the specific scheduling process is as follows: if the total share of raw materials that can be transferred out is less than the total share of raw materials that need to be transferred in, the raw material share of each raw material transfer section is reduced, and the amount is the share of raw materials that can be transferred out of each raw material transfer section. According to the production rate of each raw material transfer section from large to small, the total share of raw materials that can be transferred out is allocated to the first raw material transfer section, and the amount is the share that needs to be transferred in the first raw material transfer section. The remaining share of the first allocation is allocated to the second raw material transfer section, and the amount is the share that needs to be transferred in the second raw material transfer section. When the remaining share of a certain allocation is less than the share that needs to be transferred in the raw material transfer section, the remaining share of this allocation is allocated to the corresponding raw material transfer section, so as to allocate the raw material shares, and substitute the raw material transfer quantity and the raw material transfer quantity into the purchase cycle calculation formula , get the future purchase cycle , The quantity of raw materials required for the order.

[0047] If the total share of raw materials that can be transferred out is equal to the total share of raw materials that need to be transferred in, reduce the raw material share of each raw material transfer section by the amount of raw materials that can be transferred out of each raw material transfer section, and increase the raw material share of each raw material transfer section by the amount of raw materials that need to be transferred in of each raw material transfer section.

[0048] If the total share of raw materials that can be transferred out is equal to the total share of raw materials that need to be transferred in, reduce the raw material share of each raw material transfer section by the amount of raw materials that can be transferred out of each raw material transfer section, increase the raw material share of each raw material transfer section by the amount of raw materials that need to be transferred in of each raw material transfer section, and allocate the remaining share of raw materials after allocation to the section with the highest current production rate.

[0049] It should be added that if raw material problems occur in some sections, for example, the raw materials in some sections are damaged and cannot be used, the raw material shares of other sections can be quickly dispatched to the problem sections without affecting the normal production of other sections.
