[0002] The in-warehouse aging of tobacco raw materials is a crucial link in the tobacco logistics process, which is closely related to the quantity supply and aging quality of tobacco raw materials required for cigarette production and processing. Warehouse managers need to adjust the temperature settings of each warehouse area and regulate the aging rate of tobacco raw materials according to the aging progress of tobacco raw materials to meet the quantity of raw materials supplied for cigarette production. The in-warehouse adjustment of tobacco raw materials needs to consider indicators such as the completion rate of production tasks, the aging quality of tobacco leaves shipped out of the warehouse, and the energy consumption of the warehouse. According to future production plan requirements, the warehouse temperature is adjusted to regulate the aging progress of tobacco raw materials, which is of great significance to the supply of tobacco raw materials and the economic cost of the warehouse.

However, the existing public research results are usually based on traditional commercial logistics scenarios, and the characteristics and evaluation indicators of the incoming goods involved in these logistics scenarios are relatively similar, unlike the tobacco leaf raw material supply, which has such a variety of influencing factors. Therefore, for different storage layouts and tobacco-specific evaluation indicators, it is difficult for the classic model to cover all scenarios, and it cannot be effectively applied in the more characteristic aging adjustment and energy consumption optimization scenarios.

[0028] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example 1
[0029] In this example, the tobacco storage warehouse in Zhuantang, Hangzhou, Zhejiang Province is selected. The average monthly temperature of the warehouse location varies from 5.1℃ to 29.4℃. The warehouse has a usable area of 202,000 square meters, with 7 floors in total, each with 8 floors. Each warehouse has 24 stacks, and the available capacity of a single stack ranges from 252 to 510 pieces. The current warehouse involves a storage volume of 75,627 pieces.

[0030] This embodiment provides a method for optimizing energy consumption of a tobacco raw material warehouse based on alcoholization progress prediction, comprising the following steps: Step 1: Establish a sensory quality evaluation function for all grades of tobacco leaves based on the historical effective accumulated temperature data and sensory quality evaluation scores of tobacco leaves in stock; further establish a tobacco leaf raw material aging progress prediction model based on the sensory quality evaluation function of each grade of tobacco leaves to obtain the characteristics for evaluating the aging quality of tobacco leaf raw materials leaving the warehouse; specifically, the following steps are included: 1.1 During the whole aging process of the redried tobacco leaves from storage to delivery, the accumulated temperature collection device is used to measure the effective accumulated temperature data during the aging process of the tobacco leaves, and the measured data is transmitted to the host computer for storage and processing; 1.2 During the whole aging process, samples of tobacco leaves are taken at the same time for sensory quality evaluation; the evaluation results are combined with the effective accumulated temperature of tobacco leaves at the sampling time node to form the effective accumulated temperature-sensory quality score data point; 1.3 For multiple groups of effective accumulated temperature-sensory quality score data points of tobacco leaves of the same grade, with effective accumulated temperature as the independent variable and sensory quality score as the dependent variable, the least squares method was used to perform cubic polynomial fitting to obtain the sensory quality evaluation function of the tobacco leaves of this grade; 1.4 Repeat step 1.3 to establish a sensory quality evaluation function for all grades of tobacco leaves, and then establish a prediction model for the aging progress of tobacco leaf raw materials; based on this model, estimate the sensory quality score of tobacco leaves through their grade and effective accumulated temperature value, and predict the future aging progress of tobacco leaves in combination with their aging temperature, thereby reflecting the aging quality of tobacco leaves, which will be used for the subsequent evaluation of the overall aging quality difference index.
[0031] Step 2: According to the characteristics of production demand, aging quality and warehouse energy consumption, the optimization index for adjusting the tobacco raw material warehouse is proposed, and an energy consumption optimization model for the tobacco raw material warehouse is established based on the production demand shortage rate index function, the overall aging quality difference index function and the overall energy consumption level index function of the warehouse.
[0032] The energy consumption optimization model for tobacco raw material warehouse of the present invention includes a production demand shortage rate index function, an overall aging quality difference index function and an overall energy consumption level index function of the warehouse; the contents of each function are as follows: 2.1 According to the production demand shortage rate indicator function shown in the following formula, the degree of completion of the quantity of tobacco leaf raw materials shipped out of the warehouse to the production task demand is evaluated:
[0033] in, It is the production demand shortage rate indicator; An index of tobacco leaf raw material types; is the index of the time period; The maximum time for tobacco leaf storage; is the total number of types of tobacco leaf raw materials; For After time The estimated total outbound quantity of these tobacco leaf raw materials; For After time The total demand for tobacco leaf raw materials; 2.2 According to the overall aging quality difference index function shown in the following formula, the overall aging quality of the tobacco raw materials leaving the warehouse is evaluated:
[0034]
[0035]
[0036] in, It is the overall alcoholization quality difference indicator; For Stored in the warehouse within the time period The effective accumulated temperature increment of tobacco leaves; For Warehouse area within the time period The set temperature; The index of the warehouse area; is the index of the time period; is the non-alcoholization temperature of tobacco leaves; For the The effective accumulated temperature value of the tobacco leaf raw materials at the estimated time of shipment; For the The effective accumulated temperature value of the tobacco leaf raw material at the initial time; An index of tobacco leaf raw material types; The total number of available storage areas in the warehouse; For the The estimated time for the tobacco leaf raw materials to be shipped out of the warehouse; For the Tobacco leaf raw materials Stored in the warehouse within the time period If stored in the warehouse area If yes, it is 1, otherwise it is 0; is the total number of types of tobacco leaf raw materials; For the Sensory quality evaluation function of tobacco leaf raw materials; 2.3 According to the warehouse overall energy consumption level index function shown in the following formula, the overall energy consumption level of the warehouse during the alcoholization of tobacco raw materials is evaluated:
[0037] in, It is an indicator of the overall energy consumption level of the warehouse; The maximum time for tobacco leaf storage; is the index of the time period; The total number of available storage areas in the warehouse; The index of the warehouse area; For Warehouse area within the time period The set temperature; For The average natural temperature of the area during the time period; 2.4 The optimization direction of the three evaluation indicators is minimization. The three evaluation indicators are calculated using the priority diagram method. , , The weight value of the production demand shortage rate indicator; since the supply quantity of raw materials required for cigarette production is the basic task of the warehouse The importance of is higher than the other two indicators, and the overall alcoholization quality difference indicator The overall energy consumption level index of the warehouse are roughly equivalent in importance.
[0038] Step 3: Use genetic algorithm to solve the optimization model.
[0039] The present invention adopts a hybrid genetic taboo search algorithm to solve the energy consumption optimization model of tobacco raw material warehouse to improve the algorithm's optimization ability and search efficiency; 3.1 The decision variables are encoded using multiple sequences, which include a tobacco storage area selection sequence and a storage area temperature setting sequence, which encode the planned storage areas for various tobacco leaves and the planned set temperatures of each storage area in each time period; the initial population is randomly generated to ensure the diversity of the population; 3.2 The objective optimization function of the tobacco raw material warehouse energy consumption optimization model is used as the fitness function of the genetic algorithm:
[0040] In the formula, , , They are the production demand shortage rate index, the overall alcoholization quality difference index, and the overall energy consumption level index of the warehouse; , , are the weight values of the three indicators respectively; The weight values of the three indicators are calculated as follows: First, the priority diagram method is used to calculate the three indicators , , The score is then normalized using the sum of the indicator scores to obtain , , The weights are , , .
[0041] 3.3 The ternary tournament is used to implement the selection operation to ensure the retention and transmission of excellent individuals in each generation; during the crossover operation, single-point crossover and two-point crossover are used for the storage area selection sequence and the storage area temperature setting sequence respectively to avoid generating infeasible solutions; 3.4Use uniform mutation method with conflict detection to realize mutation operation and increase individual diversity and exploration; 3.5 Combined with the taboo search algorithm, the ability to expand the search range to the neighborhood can be improved to improve the local optimization ability; 3.6 Solve through the algorithm and finally obtain the decision variables corresponding to the optimal strategy; 3.1 to 3.5 specifically include the following steps: (1) Population initialization The population in the genetic algorithm is composed of many chromosomes, each of which is a coding sequence, representing a scheduling scheme for the warehouse energy consumption optimization adjustment problem. The initial population determines the genetic diversity of the offspring population to a certain extent. This paper considers the diversity of storage area selection and the search breadth of temperature setting in the warehouse energy consumption optimization adjustment problem, and randomly initializes the initial population. At the same time, in order to avoid conflicts in storage area selection, the storage area selection sequence is checked for outbound status. After the tobacco leaves are out of the warehouse, they will remain in the outbound status and will no longer return to the warehouse to participate in the storage area adjustment.
[0042] (2) Fitness function and selection operation Calculation using the priority diagram method , , The scores of the three indicators are 2.5, 1, and 1 respectively. The sum of the indicator scores is used for normalization to obtain , , The weights are 0.5556, 0.2222, and 0.2222 respectively.
[0043] The fitness function determines the evolutionary direction of the population, and the objective function of optimizing warehouse energy consumption is used as the fitness function of the genetic algorithm.
[0044]
[0045] After calculating the fitness value of each individual in the population, the individuals copied into the next generation population are selected through the selection operation, which can ensure that high-quality individuals survive in iterative evolution with a greater probability, thereby improving the convergence performance and search efficiency of the algorithm. By adopting the selection operation of the ternary tournament, three individuals are randomly sampled from the population, and the individuals with the best fitness are selected to enter the next generation population according to the fitness of each individual, and the rest are returned to the original population. The operation is repeated until the size of the next generation population reaches the size of the parent population. In the competition, a certain population diversity is retained, and the elite individuals in the population are allowed to enter the next generation population.
[0046] (3) Crossover operation Crossover operation is an important way for genetic algorithms to generate new individuals from parent individuals, and it also reflects the global search ability of genetic algorithms. In view of the particularity of tobacco storage area and storage area temperature setting problems in warehouse energy consumption optimization and adjustment, this paper uses single-point crossover operator and two-point crossover operator to perform sequence crossover operation.
[0047] The single-point crossover operator is used to select the sequence of tobacco leaf storage area in the encoding, and a non-zero crossover point is randomly selected in the sequence, such as Figure 1 As shown in the figure, the gene information after the crossover point in the parent individuals P1 and P2 is selected, and the positions of the two groups of genes are exchanged to obtain the offspring individuals C1 and C2. Since the selected crossover points are all non-zero, the outbound state in the offspring after the exchange is at the end of the chromosome, ensuring that the genes in each chromosome of the offspring still meet the outbound state verification.
[0048] A two-point crossover operator is used for the storage area temperature setting sequence in the coding, and two crossover points are randomly selected in the sequence, such as Figure 2 As shown, the genetic information between the two crossover points of the parent individuals P1 and P2 is selected and copied to the corresponding points of the offspring individuals C2 and C1 respectively, and then the genetic information at the remaining positions of the parent individuals P1 and P2 is copied to the corresponding points of the offspring individuals C1 and C2 respectively.
[0049] (4) Mutation operation Mutation operation is an important way to expand the search range and improve local search capabilities in genetic algorithms. By applying small disturbances to chromosomes, the diversity of the population is improved. This paper adopts uniform mutation with conflict detection. For the selection sequence of the tobacco storage area in the coding, a random number is taken from the storage area selection range with a certain mutation probability for each gene point in the sequence to replace it. After generating the random number, the tobacco storage area selection sequence needs to be constrained. If there is a conflict in the outbound state, the random number is regenerated until the constraint check is satisfied to ensure that the decision variable is a feasible solution. For the storage area temperature setting sequence in the coding, a random number is taken from the temperature setting value range with a certain mutation probability for each gene point in the sequence to replace it.
[0050] (5) Neighborhood structure In order to further improve the local optimization ability and search efficiency of the algorithm, the taboo search algorithm is combined to optimize the neighborhood range of the new population in a specific direction. For the reservoir temperature setting sequence, the neighborhood structure commonly used in sequence encoding is used to generate new solutions, such as Figure 3 As shown. Neighborhood structure 1, randomly selects two gene loci in the chromosome sequence and reverses the gene fragments between the loci. Neighborhood structure 2, randomly selects two gene loci in the chromosome sequence and exchanges the gene information at the two loci. Neighborhood structure 3, randomly selects two gene loci in the chromosome sequence and inserts the loci with the later index before the loci with the earlier index, or inserts the loci with the earlier index after the loci with the later index.
[0051] (6) Taboo table In the taboo search algorithm, the taboo table stores objects that are tabooed during the search process. Its purpose is to avoid repeated searches and guide the algorithm to search other better solution space areas. During the algorithm iteration, if the new solution generated by the neighborhood structure perturbing the current solution already exists in the taboo table, the new solution will not be used to update the current solution. The taboo table is a ring table of a specified length. When a new element is added, the oldest element in the table will be overwritten.
[0052] Step 4: Based on the solution of the optimization model, the storage stacks of the tobacco raw materials and the ambient temperature set in the warehouse are adjusted to achieve the regulation of the aging progress of the tobacco raw materials during the inventory process and the optimization of the warehouse energy consumption.
[0053] 4.1 According to the decision variables corresponding to the calculated optimal strategy, the tobacco leaf storage area selection sequence and the storage area temperature setting sequence are obtained; 4.2 According to the tobacco leaf storage area selection sequence, the corresponding stacked tobacco leaves are adjusted to the designated storage area within the specified time period; specifically, according to the storage area selection sequence, the storage area adjustment plan for the tobacco leaves in the warehouse is sorted out, and the tobacco leaf raw materials are adjusted to the designated storage area within the corresponding time period, such as shown in Table 1.
[0054] Table 1 Allocation results of tobacco storage area
[0055] 4.3 According to the warehouse area temperature setting sequence, the set temperature of the air conditioner in the warehouse area is adjusted to the specified temperature in the corresponding time period; specifically, according to the warehouse area temperature setting sequence, a warehouse area temperature setting plan for optimizing warehouse energy consumption is obtained, and the set temperature of the air conditioner in the warehouse area in the corresponding time period is adjusted to the specified temperature, as shown in Table 2.
