Abstract
Description
Technical Field
[0001] This invention relates to the technical field of transportation scheme determination, and more particularly to a method for determining a transportation scheme based on the protective validity period of the iron core packaging. Background Technology
[0002] The iron core is an intermediate product in transformer manufacturing. After receiving an order from a transformer manufacturer, the iron core manufacturer produces the corresponding iron core and then transports it to the transformer manufacturer, where it is assembled with other parts to form the transformer. The iron core is made of ferromagnetic metal materials such as silicon steel sheets, and it is highly susceptible to oxidation in humid environments or environments containing salt or acidic gases. Therefore, the iron core needs to be rust-proofed before transportation, and the effectiveness of the protective packaging must be assessed to ensure that the packaging effectively protects the iron core during transportation.
[0003] Current assessments of the protective validity period of iron core packaging only rely on testing parameters of the internal environment of the packaging, ignoring other factors such as the external environment and customer needs. This results in a high probability that the obtained protective validity period will not meet actual needs, leading to the selection of a non-optimal transportation plan and further widening the gap between the plan and reality. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a method for determining a transportation plan based on the protective validity period of the iron core packaging, so as to solve one or more problems in the prior art.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A method for determining a transportation plan based on the protective shelf life of the iron core packaging includes the following steps: Obtain order information, including customer type, timeliness requirements, and customization requirements; Multiple different pre-selected transportation plans that meet timeliness and customization requirements are generated, and the pre-selected transportation plans include transportation mode and transportation timeliness; Obtain detection parameters; Based on the testing parameters, the corresponding transportation methods, and the transportation time, the packaging protection validity period corresponding to different pre-selected transportation schemes is determined; Estimate storage time based on customer type The theoretical protection time is determined based on storage and transportation time; Determine in turn whether the protective validity period of each package exceeds or equals the theoretical protection time. If the effective period of packaging protection exceeds or equals the theoretical protection time, calculate the execution cost of the corresponding pre-selected transportation plan; Select the pre-selected transportation plan with the lowest execution cost as the transportation plan to be implemented.
[0006] Furthermore, determining the packaging protection validity period corresponding to different pre-selected transportation schemes based on detection parameters, corresponding transportation methods, and transportation timeliness includes the following steps: Determine the transportation environment coefficient based on the mode of transportation; The transportation influencing factors are determined based on the transportation environment coefficient and transportation timeliness. The initial influencing factors were determined based on humidity parameters and rust-inhibiting particle concentration. The effective period of packaging protection is calculated based on the transportation impact factor and the initial impact factor.
[0007] Furthermore, it also includes the following steps: If the effective period of packaging protection is shorter than the theoretical protection time, a repackaging plan is determined and the repackaging cost is generated. The repackaging plan and the corresponding transportation plan are combined into a pre-selected transportation plan, and the execution cost is determined based on the repackaging cost and the corresponding transportation cost.
[0008] Furthermore, determining the repackaging scheme includes the following steps: Calculate the time difference based on the packaging protection validity period and the theoretical protection time; Determine whether the time difference exceeds the preset maximum threshold. If so, then no repackaging scheme will be generated; If not, the corresponding repackaging scheme is matched from a preset database based on the time difference. The preset database stores multiple different packaging schemes and a theoretical protection validity period corresponding to each packaging scheme.
[0009] Furthermore, estimating the storage time based on customer type includes the following steps: The customer types include new customers and existing customers; If the customer type is a new customer, the preset time will be used as the storage time; If the customer type is a returning customer, retrieve the historical purchase records corresponding to the returning customer and determine the storage time based on the historical purchase records.
[0010] Furthermore, determining the storage time based on historical procurement records includes the following steps: Extract purchase time points from historical purchase records that fall within a preset time period; Calculate the average interval period for all procurement time points; The average interval period is used as the storage time.
[0011] Compared with the prior art, the beneficial technical effects of the present invention are as follows: by measuring the internal atmosphere of the packaging, and considering the transportation conditions and storage time of various transportation schemes, a transportation scheme that balances cost and effectiveness is selected. Attached Figure Description
[0012] Figure 1 The diagram shows a flowchart of a method for determining a transportation plan based on the protective validity period of iron core packaging, according to an embodiment of the present invention. Detailed Implementation
[0013] A method for determining a transportation plan based on the protective shelf life of the iron core packaging, see [link to relevant documentation]. Figure 1 This includes the following steps: S100, Obtain order information.
[0014] Order information includes customer type, delivery time requirements, and customization requirements.
[0015] The customer types include new customers and returning customers. New and returning customers are manually categorized by staff. Generally, new customers are those making their first purchase of a product or service, or potential customers completing their first valid transaction; returning customers are those with at least one prior purchase or cooperation record, possessing historical transaction data.
[0016] The timeliness requirement refers to the required delivery time of the iron core for the corresponding order.
[0017] Customization requirements refer to other requirements from customers, such as specifying the shipping method, packaging method, etc.
[0018] Each order must include customer type and time requirements, but may not necessarily include customization requirements.
[0019] S200 generates multiple pre-selected transportation solutions that meet timeliness and customization requirements.
[0020] The pre-selected transportation plan includes the mode of transportation and the delivery time.
[0021] Transportation modes include land transport, inland river transport, sea transport, air transport, and mixed transport.
[0022] Transportation timeliness refers to the transportation time required using the corresponding mode of transportation.
[0023] S300, Obtain detection parameters.
[0024] The detection parameters include humidity and rust-preventing particle concentration.
[0025] Rust-inhibiting particle concentration refers to the content of effective corrosion-inhibiting components per unit volume or unit area. In this embodiment, it is the effective VCI molecular mass released per cubic meter of air, expressed in g / m³. The higher the rust-inhibiting particle concentration, the slower the core rusts; conversely, the higher the humidity, the faster the core rusts. For example, when the external environment is set at 25 degrees Celsius and the product is not stored outdoors, with a rust-inhibiting particle concentration between 5 mg / m³ and 10 mg / m³ and a humidity between 50% and 70%, the core's shelf life is generally 4 months.
[0026] The humidity parameters and rust-preventing particle concentration were obtained by testing the internal environment of the packaging.
[0027] The specific testing method involves drilling a detection hole in the iron core packaging, then inserting a sensor probe through the hole into the packaging. The sensor probe automatically measures the humidity and rust-preventing particle concentration inside the packaging. During the testing process, the sensor probe is sealed in the detection hole, and the hole is repaired after the testing is completed.
[0028] S400. Based on the testing parameters, the corresponding transportation method, and the transportation time, determine the packaging protection validity period corresponding to different pre-selected transportation schemes.
[0029] In addition to the testing parameters mentioned above determining the effective period of packaging protection, the mode of transportation and the delivery time also affect the effective period of packaging protection. For example, compared to land transportation, the external environment of sea transportation has higher humidity, which can more easily shorten the effective period of packaging protection; and for example, transportation schemes with long delivery times are more susceptible to external interference, resulting in a shorter effective period of packaging protection.
[0030] S500 estimates storage time based on customer type.
[0031] Storage time refers to the time that a customer may store the iron core after receiving it.
[0032] S600: The theoretical protection time is determined based on the storage time and transportation time.
[0033] S700: Sequentially determine whether the protection validity period of each package exceeds or equals the theoretical protection time.
[0034] Combining storage time and transportation time with the required packaging protection period is essential to ensure that the iron core is unlikely to rust during actual customer use.
[0035] S800 If the effective period of packaging protection exceeds or equals the theoretical protection time, calculate the execution cost of the corresponding pre-selected transportation plan.
[0036] S900: Select the pre-selected transportation plan with the lowest execution cost as the transportation plan to be executed.
[0037] Once the pre-selected transportation plan meets the requirement of a sufficiently long packaging protection period, the corresponding execution cost is then considered. The transportation plan with the lowest execution cost is prioritized for implementation, balancing cost and effectiveness.
[0038] It should be noted that steps S300 and S100 can be performed simultaneously, without any order. Steps S500 and S200 are performed simultaneously.
[0039] In addition, before inspecting the inside of the packaging, its airtightness must be checked first. There are two indicators for checking the airtightness: first, whether the pressure can reach 40 kPa within 60 seconds during inflation; and second, whether the pressure can be maintained at 40 kPa for 60 seconds without leakage. If the pressure cannot reach 40 kPa within 60 seconds during inflation, it indicates that the packaging is not properly sealed or has a gap, such as improperly applied sealing tape or packaging damage. In this case, the gap needs to be located, resealed, and tested again. If the pressure can reach 40 kPa within 60 seconds but cannot be maintained without leakage for 60 seconds, it also indicates that the packaging is not properly sealed. Small gaps or micropores will allow air to escape from the packaging, requiring the gap to be located, resealed, and tested again.
[0040] In one embodiment, estimating storage time based on customer type includes the following steps: S510. If the customer type is a new customer, the preset time will be used as the storage time.
[0041] S520. If the customer type is an existing customer, retrieve the historical purchase records corresponding to the existing customer and determine the storage time based on the historical purchase records.
[0042] The preset storage time is manually set. Furthermore, different new customers can be differentiated by VIP status, with VIP new customers receiving longer preset storage times. For example, VIP new customers have a storage time of 9 months, while regular new customers have a storage time of 6 months.
[0043] Existing customers have purchase records, and their purchase frequency can be used to infer the frequency of consumption after purchasing iron cores, thus providing some reference value for storage time. New customers, however, lack purchase records, so a manually estimated preset time is needed as the storage time.
[0044] In one embodiment, determining the storage time based on historical procurement records includes the following steps: S521. Extract the purchase time points in historical purchase records that fall within a preset time period.
[0045] S522. Calculate the average interval period for all procurement time points.
[0046] S523. Use the average interval period as the storage time.
[0047] The preset time period is the historical period of the past year.
[0048] The closer the purchase time of existing customers, the more accurate the estimated storage time will be. Therefore, a preset time period can be set to filter out purchase times that are relatively close to the purchase time.
[0049] In addition, if the number of extracted purchase time points is small, the estimated storage time will often be inaccurate. Therefore, before step S522, the number of extracted purchase time points can be judged. If the number of extracted purchase time points is lower than the minimum value preset by the human, the preset time will be used as the storage time, just like for new customers. If the number of extracted purchase time points is higher than or equal to the minimum value preset by the human, then step S522 will continue to be executed.
[0050] The average interval period is obtained by averaging the intervals between all adjacent procurement time points.
[0051] In one embodiment, determining the packaging protection validity period corresponding to different pre-selected transportation schemes based on detection parameters, corresponding transportation methods, and transportation timeliness includes the following steps: S410. Determine the transportation environment coefficient based on the mode of transportation.
[0052] S420. Determine the transportation impact factors based on the transportation environment coefficient and transportation timeliness.
[0053] S430. Determine the initial influencing factor based on humidity parameters and rust-preventing particle concentration.
[0054] S440. Calculate the effective period of packaging protection based on the transportation impact factor and the initial impact factor.
[0055] The transportation environment coefficient and the transportation mode have a one-to-one correspondence. The correspondence between transportation mode and transportation environment coefficient is set manually based on transportation experience and the formula is pre-entered into the system.
[0056] Transportation methods may be a combination of multiple modes, such as land transport + sea transport, or land transport + air transport. Even with the same combination of modes, different time proportions will result in different transportation environment coefficients; for example, the coefficients for one month of land transport + one week of sea transport are different from those for one week of land transport + one month of sea transport.
[0057] Furthermore, the transportation environment coefficient is also affected by weather conditions; for example, rain or snow can increase the coefficient. Therefore, determining the coefficient requires comprehensive consideration of the mode of transport, time, and weather.
[0058] The effective period of packaging protection can be calculated using the following formula: T1=(K1*α-K2*β*α-K3*β+L1)-T2*K4 Where T1 is the effective period of packaging protection, K1, K2, and K3 are all coefficients, K4 is the transportation environment coefficient, α is the concentration of rust-preventing particles, β is the humidity parameter, L1 is a constant, and T2 is the transportation time limit. K4 is obtained by matching the preset relationship between transportation mode and transportation environment coefficient according to the transportation mode.
[0059] It can be seen that T2*K4 calculates the transportation impact factor, while the rest calculates the initial impact factor.
[0060] To ensure that there are as many transportation options as possible in step S900, the following steps are included after step S700: S710. If the effective period of packaging protection is shorter than the theoretical protection time, a repackaging plan shall be determined and the repackaging cost shall be generated.
[0061] S720. Combine the repackaging plan and the corresponding transportation plan into a pre-selected transportation plan, and determine the execution cost based on the repackaging cost and the corresponding transportation cost.
[0062] The repackaging solution includes a complete replacement solution and a replacement atmosphere solution.
[0063] One approach is to completely replace the existing packaging with new packaging materials. Different new packaging materials will result in various replacement plans. For example, one plan might consist of desiccant, rust-preventive powder, rust-preventive paper, rust-preventive film, stretch film, and other auxiliary packaging materials, with a packaging cost of approximately 200 yuan / ton and a theoretical protective period of 9 months. Another plan might consist of desiccant, rust-preventive paper, agricultural film, stretch film, and other auxiliary packaging materials, with a packaging cost of approximately 120 yuan / ton and a theoretical protective period of 6 months.
[0064] The displacement atmosphere solution involves extracting the air from the packaging and filling it with dry nitrogen, thereby extending the packaging's protective shelf life by reducing humidity and oxygen content. Generally, the overall replacement solution is more effective than the displacement atmosphere solution in improving the packaging's protective shelf life; however, the overall replacement solution is more expensive, both in terms of labor and material costs.
[0065] In one embodiment, determining a repackaging scheme includes the following steps: S711. Calculate the time difference based on the packaging protection validity period and the theoretical protection time.
[0066] S712. Obtain a packaging scheme corresponding to the detection parameters, and determine the improved threshold based on the packaging scheme.
[0067] S713. Determine whether the time difference exceeds the improved threshold.
[0068] S714. If so, then no repackaging scheme will be generated.
[0069] S715. If not, then the corresponding repackaging scheme is matched from the preset database according to the time difference. The preset database stores multiple different packaging schemes and the theoretical protection validity period corresponding to each packaging scheme.
[0070] The time difference is obtained by subtracting the packaging protection period from the theoretical protection time.
[0071] The improved threshold is obtained by matching the theoretical protection validity period of the current packaging scheme from the database, and then subtracting the theoretical protection validity period from the maximum protection validity period in the database. In other words, the improved threshold represents the maximum extension of the validity period achievable based on all the recorded packaging schemes.
[0072] Only when the time difference is less than or equal to the improvement threshold can a packaging solution that meets the improvement requirements be found from the database.
[0073] Correspondingly, the corresponding repackaging scheme is matched from the preset database based on the time difference. The target protection validity period is obtained by adding the time difference to the theoretical protection validity period of the current packaging scheme. Then, the corresponding packaging scheme is matched based on the target protection validity period and the packaging scheme is used as the repackaging scheme.
[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0075] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
