Description

Technical Field

[0001] The present invention relates to the technical field of product traceability, and in particular to a full-process traceability method and system for nutritional and health products. Background Art

[0002] Full-process traceability of nutritional and health products plays a crucial role in ensuring food safety. Once a problem arises, it can be quickly and accurately located and action taken to prevent it from escalating. For businesses, full-process traceability helps improve management and quality control capabilities, promoting sustainable development. It also facilitates effective oversight by regulatory authorities and maintains market order.

[0003] Nutritional health products usually require the extraction of nutrients from plants, medicinal materials, and biological components, and are therefore produced through multiple processes and links. Each link and process contains a large number of bioactive ingredients or organic ingredients. However, during the production process, these organic ingredients are easily deteriorated due to long-term storage. If they are not promptly removed from the production process, they will easily fail to meet production requirements and standards due to oxidation or environmental pollution. Therefore, existing technologies usually only measure process irrationality based on the inventory backlog of finished products in the production process, and thus trace the entire process of nutritional health products based on process irrationality.

[0004] However, the existing technology directly measures process irrationality based on the time interval between the production and use of the finished product, without taking into account the different timeliness of different products. That is, some products can be stored for a long time without affecting their properties, while some products cannot be stored for a long time, resulting in the calculated process irrationality being inaccurate; thereby reducing the accuracy of full-process traceability of nutritional and health products based on process irrationality. Summary of the Invention

[0005] In order to solve the problem that the existing technology directly measures process irrationality based on the time interval between the production and use of the finished product, without considering that the timeliness of different products is different, resulting in the calculated process irrationality being inaccurate, the purpose of this application is to provide a whole-process traceability method and system for nutritional and health products.

[0018] The timeliness of the finished product in each step is determined based on the normalized value of the number of production batches in each step, the product of the first timeliness of use and the second timeliness of use.

[0019] Furthermore, the process of obtaining the inventory risk includes:

[0049] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the following is a detailed description of a method and system for tracing the whole process of nutritional and health products proposed in accordance with the present invention, its specific implementation method, structure, characteristics and effects, in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment, and the specific features, structures or characteristics in one or more embodiments may be combined in any suitable form. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0050] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0051] The following describes in detail a method and system for tracing the source of nutritional and health products throughout the entire process provided by the present invention with reference to the accompanying drawings.

[0052] This application embodiment provides a whole-process traceability method for nutritional and health products. Figure 1 , which shows a flow chart of a whole-process traceability method for nutritional and health products provided by one embodiment of the present invention, the method comprising:

[0053] Step S101: In the production process of nutritional health products, obtain the finished product production quantity, finished product production time period, finished product use time period and the production and use time interval of each finished product for each production batch in each step.

[0054] For nutritional health products, some organic extracts and bioactive ingredients, or some medicinal ingredients, etc. will be added. If these ingredients are not used up in time in the process, they may easily be oxidized or polluted and affected by the environment, resulting in the nutritional health products produced not meeting the target requirements or standards. That is, the production process is dangerous. Therefore, this application conducts a risk assessment of each link by analyzing the use of the finished products generated in each link of the traceability process.

[0055] In a specific implementation of an embodiment of the present invention, the production records and usage records of nutritional health products are called through the database of the production process to obtain the finished product production quantity, finished product production time period, finished product usage time period and production and usage time interval of each finished product for each production batch in each step; the production and usage time interval is the time interval from the production of each finished product in the production batch to its use in the production process; the finished product production time period is the time period from the start of production to the completion of production of each production batch; the finished product usage time period is the time period from the start of use to the completion of use of the finished product produced by each production batch in the production process.

[0056] Step S102: In each step, the timeliness of the finished products in each step is determined based on the number of production batches and the relative continuity of the finished product production time period and the finished product usage time period of each production batch; the inventory risk of each production batch is determined based on the timeliness of the finished products and the usage of the finished products of other batches before the finished product usage time period of each production batch.

[0057] Taking the production process of calcium nutritional health products as an example, since calcium itself is a mineral with a long shelf life and will not expire or deteriorate, calcium supplements may have some other ingredients added to them. For example, probiotics are added to calcium supplements to promote intestinal health. Since the shelf life of active microorganisms is usually short, they are easily affected by environmental factors such as temperature and humidity; some calcium supplements may include extracts from natural plants, such as vitamin K2, which helps calcium deposition in bones. The shelf life of some natural extracts may be relatively short; if certain sensitive vitamins such as vitamin C or enzymes are added to calcium supplements, these ingredients may also have a short shelf life and need to be consumed as soon as possible during production. Then for the same link, in order to ensure long-term production stability and spare redundancy, a part of inventory will be produced. For finished products with timeliness, it is more inclined to the feature of "first produce, first use", and try to avoid the problem of finished product deterioration caused by long-term inventory. For products without timeliness, since the storage time does not affect their properties, the spare and redundant quantities can be stored all the time and will only be used when needed. Therefore, this application obtains the timeliness of the finished products of this link by judging whether the use of products of all production batches in a link shows a time sequence feature.

[0058] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the timeliness of the finished product includes:

[0059] Obtain the production start time representing the first moment of the finished product production time period and the usage start time representing the first moment of the finished product usage time period for each production batch in each step link; in each step link, take each production batch as the target batch in turn; and take the time period between the production start time and the usage start time of the target batch as the target time period of the target batch.

[0060] During the target time period, the number of other production batches with both corresponding production start times and usage start times is used as the target batch's usage delay degree. The usage delay degrees of all production batches are counted, and the mean of the usage delay degrees of all production batches in each step is negatively correlated to determine the first usage timeliness of each step. During the target time period, if a production batch has both a production start time and a usage start time, it means that the production start time of the production batch is after the target batch, but it is used before the target batch. To a certain extent, this indicates that the timeliness of the target batch is not strong. Moreover, the more other production batches with both production start times and usage start times, the worse the timeliness of the target batch. Therefore, the greater the first usage timeliness, the stronger the timeliness of the finished product.

[0061] The time interval between the last moment of the finished product production time period and the first moment of the finished product usage time period of each production batch is taken as the production usage interval of each production batch; the mean of the production usage intervals of all production batches in each step link is negatively correlated to determine the second usage timeliness of each step link; the shorter the production time and usage time interval of the production batch, the faster it will be used; that is, the greater the second usage timeliness, the stronger the timeliness of the finished product.

[0062] For each step, the more production batches it corresponds to, the more times the step is produced and the higher its importance. Therefore, the production batch data is further used as a weight to determine the timeliness of the finished product of each step based on the number of production batches, the first timeliness of use, and the second timeliness of use in each step; wherein the number of production batches, the first timeliness of use, and the second timeliness of use in each step are all positively correlated with the timeliness of the finished product. Preferably, in some possible implementations of the embodiments of the present invention, the process of determining the timeliness of the finished product of each step based on the number of production batches, the first timeliness of use, and the second timeliness of use in each step includes:

[0063] The timeliness of the finished product in each step is determined based on the normalized value of the number of production batches in each step, the product of the first timeliness of use and the second timeliness of use.

[0064] In a specific implementation of the embodiment of the present invention, the process of obtaining the timeliness of the finished product is expressed by the formula: ;in, The first step in the production process of nutritional health products Timeliness of finished products in each step; The first step in the production process of nutritional health products The number of production batches for each step; For the In the first step the extent to which the use of a production batch is delayed; is an exponential function with a natural constant as its base; For the Timeliness of first use in each step; For the In the first step The production and use interval of each production batch; is a linear normalization function; For the The second timeliness of use in each step link; it should be noted that when the finished product production time period or the finished product use time period of a production batch in a certain step link does not exist, 0 is used as the corresponding first timeliness of use and the second timeliness of use, so that the embodiment is more complete.

[0065] For time-sensitive links, the greater the timeliness, the less likely it is that there will be inventory backlogs in this link. If there is inventory backlogs, it will easily lead to the deterioration of the finished product. Therefore, the timeliness of the finished product is used as a weight combined with the usage of other batches of finished products before the finished product usage period to obtain a more accurate inventory risk.

[0066] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining inventory risk includes:

[0067] Before the start time of use of the target batch, the production batch that exists at the corresponding production start time but does not exist at the use start time is used as the inventory batch corresponding to the target batch; the ratio between the cumulative value of the finished product production quantity of all inventory batches corresponding to the target batch and the finished product production quantity of the target batch is used as the reference inventory rate of the target batch; the reference inventory rate of each production batch in each step link is calculated; based on the product of the timeliness of the finished product and the reference inventory rate of each production batch in the corresponding step link, the inventory risk of each production batch in each step link is determined.

[0068] According to the definition of inventory batches, inventory batches are finished products that have been produced before the target batch but have not been used, that is, finished products that have accumulated or been stockpiled. Therefore, the larger the cumulative value of the production quantity of finished products of all inventory batches corresponding to the target batch, the more inventory accumulation, and the higher the possibility of inventory phenomenon in the target batch; and on this basis, the greater the timeliness of the finished products corresponding to the steps of the target batch, the greater the impact of the inventory phenomenon will be, and the corresponding inventory risk will naturally be higher; among them, in the calculation process of the reference inventory rate, using the production quantity of finished products of the target batch as the denominator can determine the inventory accumulation impact in the dimension of relative size, so that the obtained reference inventory rate is more robust; the value of the reference inventory rate usually calculated is below 2, and exceeding 2.5 usually means that the inventory accumulation is more serious.

[0069] In a specific implementation of the embodiment of the present invention, the process of obtaining the inventory risk is expressed by the formula: ;in, For the In the first step The hazard of stocking a production batch; For the In the first step The cumulative value of the finished product production quantity of all inventory batches corresponding to the production batch; For the In the first step The number of finished products produced per production batch; For the In the first step Reference inventory rate corresponding to each production batch; The first step in the production process of nutritional health products The timeliness of the finished products in each step.

[0070] Step S103: Determine the degree of abnormal inventory accumulation in each step based on the temporal fluctuations in the inventory risk of each production batch in each step; determine the link risk of each step based on the inventory risk of the production batch corresponding to the final finished product usage time period and the degree of abnormal inventory accumulation.

[0071] For the production process of nutritional health products, the use of many added ingredients has certain limitations. For example, the raw materials of some products are difficult to obtain or the extraction efficiency of the raw materials is very low (for example, extracting organic matter from plants and herbs requires a large amount of raw materials to extract part of it, and the increase in the amount of raw materials in the reactor will also reduce the extraction efficiency. In order to control costs and avoid waste, it is necessary to reserve them in batches). This will result in a production batch in the link being unable to produce all the finished products, and it will result in the finished products of multiple production batches needing to be accumulated first, and then consumed once or in batches when the next link is produced. When the above situation occurs, the inventory rate will be extremely high at some time, but it is actually a normal consumption situation. Therefore, this application analyzes the changes in the inventory rate of each link in historical production batches to determine whether it is necessary to accumulate some finished products as reserves and then use them for subsequent production to obtain the risk of the link.

[0072] First, based on the above steps, the inventory risk of each link is obtained. If accumulation is required, that is, if normal inventory accumulation is required, the size of the inventory risk will show a cumulative increase, and after accumulating to a certain amount, it will be used in large quantities, that is, the inventory risk will increase slowly and for a long time, and decrease quickly and for a short time; in abnormal cases, that is, when adjustments are required, the situation will be the opposite of the above.

[0073] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the abnormal degree of inventory accumulation includes:

[0074] Arrange the inventory risk of all production batches in each step in the order of the corresponding start time of use to determine the inventory risk sequence; perform curve fitting on the inventory risk sequence to determine the inventory risk curve;

[0075] In the inventory risk curve, the difference between each maximum value and the previous minimum value is taken as the local range of each maximum value; the time interval between the start time of use of the production batch corresponding to each maximum value and the start time of use of the production batch corresponding to the previous minimum value is taken as the local interval of each maximum value; the inventory accumulation degree of each maximum value is determined based on the ratio between the local range and the local interval; the cumulative value of the inventory accumulation degree of all maximum values ​​in the inventory risk curve of each step link is normalized to determine the abnormal degree of inventory accumulation in each step link.

[0076] For links that require accumulation of raw materials, the maximum point is the time point corresponding to sufficient accumulation, and the minimum point is the time point when a new round of accumulation begins after consumption. Therefore, for each accumulation process corresponding to the minimum to maximum point, the more accumulated inventory and the shorter the accumulation time, the greater the degree to which the inventory rate of this link needs to be adjusted. That is, for each maximum value, the smaller the corresponding local interval and the greater the local range, the greater the corresponding maximum value's inventory accumulation degree; finally, the inventory accumulation degree of all maximum values ​​is combined, and the degree of abnormal inventory accumulation of each step link is characterized as a whole by accumulation. In a specific implementation of an embodiment of the present invention, the process of obtaining the abnormal degree of inventory accumulation is expressed by the formula: ; For the The abnormal degree of inventory accumulation in each step; For the The number of maximum values ​​that exist before the minimum value in the inventory risk curve of each step; For the The previous minimum value in the inventory risk curve of the step link exists The local range of the maximum value, that is, the The difference between a maximum value and the previous minimum value; For the The previous minimum value in the inventory risk curve of the step link exists local intervals of maxima; is a linear normalized function. The greater the abnormality of the corresponding inventory accumulation, the more likely it is that it is not a normal inventory accumulation, and the greater the risk of the corresponding link.

[0077] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the link risk includes:

[0078] The riskiness of each step is determined by normalizing the product of the degree of abnormal inventory accumulation and the inventory riskiness of the production batch corresponding to the final finished product usage period of each step. For each step, the greater the inventory riskiness of the production batch corresponding to the final finished product usage period, the more serious the inventory accumulation at that step. This, combined with the degree of abnormal inventory accumulation, which represents the cumulative effectiveness or cumulative abnormality of that step, provides a more accurate comprehensive representation of the riskiness of the step, further enhancing the accuracy of subsequent process irrationality analysis based on the riskiness of the step.

[0079] In a specific implementation of the embodiment of the present invention, the process of obtaining the link risk is expressed by the formula: ;in, For the The risk of each step; For the The abnormal degree of inventory accumulation in each step; For the The inventory risk of the production batch corresponding to the final finished product usage period of each step.

[0080] Step S104: Determine the irrationality of the production process of the nutritional health product based on the risk of each step and the overall size of the corresponding production and use time interval; and trace the entire process of the nutritional health product based on the irrationality of the process.

[0081] After the operations from step S101 to step S103, the link hazards of all steps are obtained. When tracing the production process of nutritional health products, it is necessary to judge the hazards of the batches used in all links of a production. If the finished product used in this step is accumulated in inventory and the hazard of this step is greater, it means that the finished product used in this step is more likely to have deteriorated, and the quality of the nutritional health products produced this time needs to be strictly inspected and reviewed.

[0082] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining process irrationality includes:

[0083] In each production batch of each step, the time interval between the completion of production and the start of use of each finished product is used as the finished product lifespan of each finished product. Therefore, the relative lifespan of each step is further determined based on the overall standard deviation of the finished product lifespans of each finished product used in each step. The relative lifespan is obtained by taking the mean of the finished product lifespans of all finished products used in all production batches of each step as the reference lifespan of each step; taking the mean of the reference lifespans of all steps as the standard lifespan; and taking the ratio between the reference lifespan and the standard lifespan as the relative lifespan of each step. The longer the finished product lifespan of each finished product, or the greater its relative lifespan, the more likely it is to be inventory. If the risk factor for this step, indicating the impact of inventory accumulation, is higher, then the risk factor for that step is higher, and the overall process irrationality is greater. Therefore, the product of the relative lifespan of each step and the risk factor of the corresponding step is used as the weighted risk factor of each step.

[0084] In a specific implementation of the embodiment of the present invention, the process of obtaining the weighted risk is expressed by the formula: ;in, For the The weighted risk of each step; For the The risk of each step; For the The average of the service life of all finished products used in each step, also known as the reference service life; It is the average of the reference usage time in all steps, that is, the standard usage time, and its value is greater than 0; For the The relative usage time of each step link, if the value is greater than 1, it means that the finished product used this time is likely to be in stock. If the step link is easily affected by the inventory, that is, the link risk is greater, then the irrationality of the production process should be greater. Considering that when determining the irrationality of the process by the average of the weighted risks of all steps and links, it is easy for some links to have higher risks, but the risks are diluted by other links. However, in fact, as long as there are steps and links with lower weighted risks, it can be said that the rationality of the process is poor. Therefore, among all the steps and links, the positive correlation mapping value of the largest weighted risk is used as the first judgment risk; the average of the weighted risks of all steps and links is used as the second judgment risk; the maximum value between the first judgment risk and the second judgment risk is used as the process irrationality of the production process of nutritional health products; the maximum value is selected as the final calculated process irrationality by the two methods of calculating the risk, so that the robustness and accuracy of the obtained process irrationality are higher.

[0085] In a specific implementation of the embodiment of the present invention, the process of obtaining process irrationality is expressed by the formula: ;in, The irrationality of the production process of nutritional health products; Select the function for the maximum value; The maximum value of the weighted risk of all steps in the production process of nutritional health products; The preset positive correlation adjustment parameter is set to 0.7 and can be adjusted according to the specific implementation environment. Setting the preset positive correlation adjustment parameter to less than 1 can prevent the unreasonable and exaggerated process caused by excessive weighted risk of a single step.
