Description

Technical Field

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

[0002] The whole process traceability of nutritional and health products plays a vital role, and traceability can ensure the safety of food. Through traceability, once a problem occurs, it can be quickly and accurately located and measures can be taken to avoid the expansion of the problem. For enterprises, full process traceability helps to improve management level and quality control capabilities, promote the sustainable development of enterprises; and is conducive to effective supervision by regulatory authorities and maintaining market order.

[0003] Nutritional health products usually require the extraction of nutrients from plants, medicinal materials, and biological components, and therefore are 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 the irrationality of the process based on the inventory backlog of finished products in the production process, thereby tracing the entire process of nutritional health products based on the irrationality of the process.

[0004] However, the existing technology directly measures the process irrationality based on the time interval from the production to the use of the finished product, without taking into account that different products have different timeliness, 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 the whole process traceability of nutritional health products based on process irrationality. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of a method and system for tracing the whole process of nutritional 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 used for descriptive purposes only and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0022] 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.

[0023] The specific scheme of the whole-process traceability method and system for nutritional and health products provided by the present invention is described in detail below with reference to the accompanying drawings.

[0024] 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 an embodiment of the present invention, the method comprising: Step S101: In the production process of nutritional health products, 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 of each production batch in each step are obtained.

[0025] 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, it is easy to be oxidized or polluted and affected by the environment, resulting in the produced nutritional health products 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.

[0026] 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 between the production of each finished product in the production batch and 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 products produced by each production batch in the production process.

[0027] 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 use time period of each production batch; the inventory risk of each production batch is determined based on the finished product timeliness and the use of finished products of other batches before the finished product use time period of each production batch.

[0028] Take 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 the inventory will be produced. For finished products with timeliness, they are more inclined to the feature of "first come, first served" to avoid the problem of finished product deterioration due to long-term inventory. For products without timeliness, the storage time does not affect their properties, so 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 products of all production batches in a link are used in a time sequence.

[0029] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the timeliness of the finished product includes: 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; 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.

[0030] In the target time period, the number of other production batches with both the corresponding production start time and the use start time is used as the use delay degree of the target batch; the use delay degrees of all production batches are counted, and the mean of the use delay degrees of all production batches in each step link is negatively correlated to determine the first use timeliness of each step link. In the target time period, if both the production start time and the use start time of a production batch exist, it means that the production start time of the production batch is after the target batch, but it starts to be used earlier than the target batch, which can show to a certain extent that the timeliness of the target batch is not strong, and the more other production batches with both the production start time and the use start time, the worse the timeliness of the target batch; therefore, the greater the first use timeliness, the stronger the timeliness of the finished product.

[0031] The time interval between the last moment of the finished product production time period and the first moment of the finished product use time period of each production batch is taken as the production use interval of each production batch; the means of the production use intervals of all production batches in each step link are negatively correlated to determine the second use timeliness of each step link; the shorter the production time and use time interval of the production batch, the faster it will be used; that is, the greater the second use timeliness, the stronger the timeliness of the finished product.

[0032] 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 according to 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 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 according to the number of production batches, the first timeliness of use, and the second timeliness of use in each step includes: 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.

[0033] 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 The timeliness of finished products in each step; The first step in the production process of nutritional health products The number of production batches in each step; For the Step 1 the extent to which the use of a production batch is delayed; is an exponential function with a natural constant as base; For the Timely use of the first step of each link; For the Step 1 The production and use interval of each production batch; is a linear normalization function; For the The second timeliness of use of a 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 second timeliness of use to make the embodiment more complete.

[0034] For time-sensitive links, the greater the timeliness, the less likely there should 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.

[0035] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the inventory risk includes: 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; the inventory risk of each production batch in each step link is determined 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.

[0036] 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 been accumulated or stockpiled. Therefore, the larger the cumulative value of the finished product production quantity 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 finished product production quantity 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 reference inventory rate usually calculated is below 2, and exceeding 2.5 usually means that the inventory accumulation is more serious.

[0037] 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 Step 1 The hazard of stocking production batches; For the Step 1 The cumulative value of the finished product production quantity of all inventory batches corresponding to the production batch; For the Step 1 The number of finished products produced for each production batch; For the Step 1 Reference inventory ratio corresponding to production batches; The first step in the production process of nutritional health products The timeliness of the finished products in each step.

[0038] Step S103: Determine the degree of abnormal inventory accumulation in each step based on the fluctuations in the inventory risk of each production batch in each step; determine the 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.

[0039] With regard to 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 one 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, it will cause the inventory rate to 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 the historical production batches to determine whether it is necessary to accumulate some finished products as reserves and then use them for subsequent production, so as to obtain the risk of the link.

[0040] 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 the inventory risk will decrease quickly and for a short time; and in abnormal circumstances, that is, when adjustments are required, the situation will be the opposite of the above.

[0041] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the abnormal degree of inventory accumulation includes: Arrange the inventory hazards of all production batches in each step in the order of the corresponding start time of use to determine the inventory hazard sequence; perform curve fitting on the inventory hazard sequence to determine the inventory hazard curve; 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 use start time of the production batch corresponding to each maximum value and the use start time 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 according to 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.

[0042] For the links that need to accumulate 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 starts after consumption. Therefore, for each accumulation process corresponding to the minimum to the 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 of inventory accumulation; finally, the inventory accumulation degree of all maximum values ​​is combined, and the abnormal degree of inventory accumulation of each step link is characterized as a whole by accumulation. In a specific implementation method 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 degree of abnormal inventory accumulation at 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 difference between the 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.

[0043] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the link risk includes: Normalize the product of the degree of abnormal inventory accumulation and the inventory risk of the production batch corresponding to the final finished product use time period of each step to determine the link risk of each step. For each step, the greater the inventory risk of the production batch corresponding to the final finished product use time period, the more serious the inventory accumulation of the step. On this basis, the degree of abnormal inventory accumulation that characterizes the cumulative effectiveness or degree of abnormal accumulation of the step is combined to perform a more accurate comprehensive characterization of the link risk, so that the subsequent process irrationality obtained based on the link risk is more accurate.

[0044] 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 degree of abnormal inventory accumulation at each step; For the The inventory risk of the production batch corresponding to the final finished product use period of each step.

[0045] 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.

[0046] After operating through steps S101 to S103, the hazards of all steps are obtained. When tracing the production process of nutritional health products, it is necessary to determine the hazards of the batches used in all links of a production. If the finished product used in this step is an inventory pile and the hazard of this step is greater, it means that the finished product used in this step is more likely to deteriorate, and the quality of the nutritional health products produced this time needs to be strictly sampled and reviewed.

[0047] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining process irrationality includes: In each production batch of each step, the time interval between the moment when each finished product is completed and the moment when it starts to be used is taken as the finished product use time of each finished product. Therefore, the relative use time of each step is further determined according to the overall standard deviation of the finished product use time of each finished product in each step; wherein, the acquisition process of the relative use time includes: taking the mean of the finished product use time of all finished products in all production batches of each step as the reference use time of each step; taking the mean of the reference use time of all steps as the standard use time; taking the ratio between the reference use time and the standard use time as the relative use time of each step. The longer the finished product use time of each finished product, that is, the greater the relative use time, the greater the possibility of belonging to inventory. If the link danger that represents the impact of inventory accumulation is greater at this time, it means that the step is more dangerous and the overall process irrationality is greater. Therefore, the product between the relative use time of each step and the corresponding link danger is further taken as the weighted danger of each step.

[0048] 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 the steps, which is also 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 use 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 is dangerous, then the irrationality of the production process should be greater. Considering that when the irrationality of the process is determined by the average of the weighted dangers of all steps, it is easy for some links to have higher dangers, but the danger is diluted by other links. However, in fact, as long as there are steps with lower weighted dangers, it can be said that the rationality of the process is poor. Therefore, among all the steps, the positive correlation mapping value of the largest weighted danger is used as the first judgment danger; the average of the weighted dangers of all steps is used as the second judgment danger; the maximum value between the first judgment danger and the second judgment danger is used as the process irrationality of the production process of nutritional health products; the maximum value is selected from the two methods of calculating and judging dangers as the final calculated process irrationality, so that the obtained process irrationality is more robust and accurate.

[0049] 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 function for maximum value; It is 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, which can be adjusted according to the specific implementation environment. By setting the preset positive correlation adjustment parameter less than 1, it can prevent the unreasonable and exaggerated process caused by excessive weighted risk of a single step. The number of steps in the production process of nutritional health products; The first step in the production process of nutritional health products The weighted risk of each step; First determine the danger; This is the second step to determine the risk.

[0050] Finally, the rationality of the production process is measured by the obtained process irrationality, so as to trace the whole process of the nutritional health product; preferably, in some possible implementation methods of the embodiment of the present invention, the process of tracing the whole process of the nutritional health product according to the process irrationality includes: When the process irrationality is less than the preset rationality threshold, the production process of the nutritional health product is judged to be reasonable, and no process adjustment instruction is issued; when the process irrationality is greater than or equal to the preset rationality threshold, the production process of the nutritional health product is judged to be unreasonable, and a process adjustment instruction is issued, thereby adjusting the inventory rate and production situation of the finished product in each link, so as to trace the whole process of the nutritional health product. In a specific embodiment of the present invention, the preset rationality threshold is set to 0.65, which can be adjusted by itself.

[0051] To summarize, firstly, the timeliness of the finished products is adaptively determined based on the continuity of the finished product production to the finished product use of each production batch in the step link and the number of production batches, so as to obtain a more accurate inventory risk by taking the timeliness of the finished products as the weight and combining it with the use of other batches of finished products before the finished product use period; then, a more accurate inventory risk analysis is performed in combination with the time series changes and fluctuations in the inventory risk of each production batch in the step link to determine the abnormal degree of inventory accumulation, and on this basis, a more accurate link risk measurement is performed in combination with the inventory risk; finally, on the basis of the link risk, a more accurate adaptive determination of the process irrationality is performed in combination with the production and use time interval that characterizes the inventory accumulation, so that the accuracy of the whole process traceability of nutritional and health products based on process irrationality is higher.
