Description

Technical Field

[0001] The invention belongs to the technical field of production management, and in particular relates to a process-based production and marketing linkage management system for chemical industry production. Background Art

[0002] Chemical products cover many fields in today's society, from daily consumer goods to high-tech applications, from environmental protection to medical health, all of which demonstrate the important role of chemical products in promoting social development and improving the quality of life. However, with the rapid development of the chemical industry, competition and problems faced are becoming increasingly prominent. Among them, how to make chemical production more efficient through digitalization and intelligence is an issue that needs to be solved urgently.

[0003] Since the production of chemical products usually involves complex process production processes, the coordination and management of these production processes require a high degree of professional knowledge and system support, which leads to information asymmetry and difficulty in collaboration between production and sales. At the same time, the production department pays more attention to production capacity and resource utilization efficiency, while the marketing department pays attention to market demand and customer feedback. The different focuses between the two also aggravate the difficulty of collaboration between the two. In this case, it is easy to cause a split between production and sales, resulting in the inability of the production department to accurately predict market demand, which may lead to unreasonable production planning, and then there is a risk of product inventory backlog, increased storage costs and capital occupation, or production shortages due to supply and demand imbalances, and missed market opportunities.

[0004] In addition, even if production and sales have formed a certain degree of collaboration, in most cases the mode of collaboration still tends to be one-way collaboration in production, that is, production adjustments are made according to market demand, and insufficient attention is paid to production-oriented sales collaboration, which can easily cause the company to passively respond to market demand and lack opportunities for proactive adjustments. This will limit the company's market sensitivity and make it difficult to quickly adjust strategies and product portfolios in a highly competitive market, which is not conducive to the long-term operation of the company. Summary of the invention

[0005] In view of this, the present invention aims to propose a process-based chemical industry production and sales linkage management system, which extracts advantageous product information from the production records and sales records of chemical products, provides an information sharing platform for producers and sellers, and realizes periodic two-way linkage management of production and sales.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a process-based chemical industry production and marketing linkage management system, including the following modules: a product-related record retrieval module, which is used to count the number of product types produced by chemical companies and retrieve the sales records and production records of various products in the current management cycle.

[0007] The sales value evaluation module is used to parse the sales status indicators from the sales records of various products in the current management cycle, including market coverage, market demand and market share trends, so as to evaluate the sales value coefficients of various products in the current management cycle.

[0008] The production value evaluation module is used to parse the production status indicators from the production records of various products in the current management cycle, including resource consumption rate, production efficiency, and production line utilization rate, thereby evaluating the production value coefficients of various products in the current management cycle.

[0009] The product advantage grade classification module is used to classify the advantage grades of various products based on their sales value and production value in the current management cycle.

[0010] The production schedule adjustment module is used to adjust the currently generated production schedule based on the advantage levels corresponding to various products.

[0011] The sales object adjustment module is used to determine key products and non-key products based on the advantage levels corresponding to various products, and thus determine the sales direction based on the market coverage, market demand and market share trend of key products in the current management cycle. At the same time, it is used to identify whether non-key products have the conditions for sales market conversion. If so, sales market conversion of non-key products is carried out.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention evaluates the sales value and production value of various products by regularly retrieving the production and sales records of various chemical products in the enterprise, thereby refining the advantage levels of various products and providing timely feedback to the production and sales departments, providing an information sharing platform for the production and sales departments without the need for human participation, breaking the collaboration limitations caused by the asymmetry between the production and sales departments, and achieving efficient and close contact between the sales and production departments, which is conducive to enhancing the execution and responsiveness of the overall team.

[0013] 2. The present invention associates the advantage level of the product with the production schedule, so that the production department can adjust production more accurately according to market demand, give priority to the production of products with strong market demand and strong competitiveness, thereby avoiding overproduction or shortage and improving the accuracy and response speed of production plans.

[0014] 3. The present invention associates the superiority level of the product with the sales target, allowing the sales department to focus on the sales of superior products. This reflects the targeted adjustment of sales targets based on production, and further formulates sales strategies and market positioning more accurately and sensitively, thereby actively responding to market demand, improving product awareness and market share in the target market, and focusing on the sales of superior products. This helps companies optimize resource allocation and cost control, and by more effectively managing sales processes and resource inputs, can reduce sales operating costs and improve overall sales efficiency and profit margins.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 As shown, the present invention proposes a process-based chemical industry production and marketing linkage management system, including a product association record retrieval module, a sales value evaluation module, a production value evaluation module, a product advantage grade classification module, a production scheduling adjustment module and a sales object adjustment module, wherein the product association record retrieval module is respectively connected to the sales value evaluation module and the production status evaluation module, the sales value evaluation module and the production status evaluation module are both connected to the product advantage grade classification module, and the product advantage grade classification module is respectively connected to the production scheduling adjustment module and the sales object adjustment module.

[0021] The product association record retrieval module is used to count the number of product types produced by the chemical enterprise and retrieve the sales records and production records of various products in the current management cycle.

[0022] It should be understood that the management cycle is set up so that the retrieved sales records and production records are limited to the current time, which can ensure that the retrieved sales records and production records are concentrated in the most recent period of time. This can more truly and accurately reflect the current sales and production situation of chemical products, avoid outdated records affecting the analysis results, and enhance the reliability and predictability of the analysis. At the same time, focusing on analyzing the most recent sales records and production records can more efficiently extract key information, reduce unnecessary historical data processing and storage pressure, and more importantly, form a cyclical and dynamic production and sales linkage management.

[0023] In the example explained above, the management cycle may be set to be once every six months.

[0024] It should be added that modern enterprises usually use sales management systems to manage the sales process. When customers place orders to purchase products, these systems can automatically record and track sales orders to form sales orders. The sales orders contain detailed information about the orders, such as product type, sales volume, sales price, sales area, delivery time, etc., to form a complete sales record.

[0025] It should be further added that in modern production, automated production systems are often used to manage the production process. Based on sales orders, the production department will formulate a production plan and then generate a production order. The production order contains information such as a list of raw materials required for production and the production process. The production operator starts the production line according to the production order. The automated production system can track the operating status of the production line, the use of raw materials, and the production progress of the product in real time to form a complete production record.

[0026] The sales value evaluation module is used to parse sales status indicators from the sales records of various products in the current management cycle, specifically including market coverage, market demand and market share trends, thereby evaluating the sales value of various products in the current management cycle.

[0027] The implementation diagram of using sales records to evaluate product sales value is as follows: Figure 2 shown.

[0028] As a specific implementation of the above plan, the sales status indicators are specifically analyzed as follows: (1) Market coverage: Compare the sales regions corresponding to each sales record of various products in the current management cycle, remove duplicate sales regions, and count the number of sales regions after removal of duplicates.

[0029] It should be noted that the sales area mentioned in the present invention refers to a planned administrative area, such as a province.

[0030] Divide the number of sales regions for various products after deduplication by the number of sales records in the current management cycle to obtain the market coverage of various products in the current management cycle.

[0031] The more consistent the number of sales regions after deduplication is with the number of sales records, the more each sales record has a unique sales region, which means the sales regions are more widely covered.

[0032] (2) Market demand: Compare the timestamps of adjacent sales records of various products in the current management cycle to obtain the interval length of adjacent sales records of various products in the current management cycle.

[0033] The average of the intervals between adjacent sales records of the same product in the current management cycle is calculated, and an exponential function is constructed with the reciprocal of the set constant as the base and the ratio of the average interval to the current management cycle as the exponent to calculate the market demand for various products in the current management cycle. The shorter the interval between adjacent sales records, the faster the sales speed and the higher the sales activity, which in turn reflects the high demand for the product in the market.

[0034] (3) Market share trend: With sales time as the horizontal axis and sales volume as the vertical axis, the timestamps and sales volumes of each sales record of various products in the current management cycle are marked in the constructed coordinate system to obtain the sales volume change curve of various products in the current management cycle.

[0035] The sales volume change rate is obtained by obtaining the slope of each point on the sales volume change curve and performing differential calculation.

[0036] It should be added that the difference calculation of sales volume change rate mentioned above is to calculate the difference in sales volume at adjacent sales time, and then divide it by the time interval to obtain the average change rate of sales volume as the sales volume change rate. The sales volume change rate calculated by the difference method intuitively reflects the growth or decline rate of sales volume in different time periods, which is easier for managers to understand and compare. In addition, in the time series of sales volume, the difference method is a common means to test the stability of data. If there is a seasonal effect in the original sales volume data, the difference can make the data stable, thereby eliminating the seasonal effect and highlighting the long-term trend, thereby providing more accurate data support for the analysis results.

[0037] Import the sales volume change rate of various products in the current management cycle into the analytical formula The market share trend of various products in the current management cycle is obtained. λ represents the sales volume change rate. Since the sales volume change rate can be positive or negative, when the sales volume change rate is positive, it means that the sales volume is increasing, and when the sales volume change rate is negative, it means that the sales volume is decreasing. It can be seen that the greater the positive sales volume change rate, the greater the market share trend.

[0038] As a further implementation of the above plan, the sales value coefficient of various products in the current management cycle is evaluated as follows: the market coverage, market demand and market share trend of various products in the current management cycle are accumulated to obtain the sales value coefficient of various products in the current management cycle.

[0039] The present invention analyzes the sales value of products from three dimensions: market coverage, market demand and market share trend, so as to fully and deeply understand the performance and influencing factors of products in the market.

[0040] The production value evaluation module is used to parse production status indicators from the production records of various products in the current management cycle, specifically including resource consumption rate, production efficiency, and production line utilization rate, thereby evaluating the production value of various products in the current management cycle.

[0041] The implementation diagram of using production records to evaluate product production value is as follows: Figure 3 shown.

[0042] In the preferred implementation of the above scheme, the analysis process of the production status indicator is as follows: (a) Resource consumption rate: Arrange the production records of various products in the current management cycle in chronological order according to the timestamps.

[0043] The raw material consumption, energy consumption and production volume are extracted from each production record of various products in the current management cycle, and the resource consumption rate of each production record is calculated. The specific calculation is to divide the raw material consumption and energy consumption of each production record by the production volume, and the calculation results are accumulated to obtain the resource consumption rate of each production record.

[0044] It should be explained that the energy consumption mentioned above includes but is not limited to the consumption of electricity, water resources and gas resources.

[0045] The resource consumption rate of each production record of the same product in the current management cycle is calculated by variance, and the calculation result is compared with the boundary variance set by the system. If the variance of the resource consumption rate of each production record of a certain product in the current management cycle is greater than the boundary variance, it means that the resource consumption distribution of this product in the current management cycle is relatively scattered. At this time, the average value is easily affected by extreme values ​​and cannot represent the resource consumption status of this product in the current management cycle. By taking the resource consumption rate of the last production record of this product in the current management cycle as the resource consumption rate of this product in the current management cycle, it can reflect the change trend closest to the current in the overall time series, has better timeliness, and can capture the resource consumption status more sensitively. On the contrary, it means that the resource consumption distribution of this product in the current management cycle is relatively concentrated. At this time, the average value can effectively represent most of the data points in the data set and reflect the central trend of the data. Based on this, the average value of the resource consumption rate of each production record of this product in the current management cycle is taken as the resource consumption rate of this product in the current management cycle.

[0046] (b) Production efficiency: The production time and production volume of each product in the current management cycle are extracted from each production record, and the production efficiency of each production record is calculated, where

[0047]

[0048] The production time mentioned above refers to the time from the start to the end of the production line, that is, the running time of the production line.

[0049] The production efficiency of each production record of various products in the current management cycle is similarly referred to the resource consumption rate analysis method to obtain the production efficiency of various products in the current management cycle.

[0050] (c) Production line utilization: The operating time of the equipment is extracted from each production record of various products in the current management cycle, and then the operating time of each equipment is divided by the production time and the minimum value is taken to obtain the production line utilization corresponding to each production record.

[0051] The minimum value is taken from the above to obtain the production line utilization rate corresponding to each production record. This is because the efficiency of the production line is often limited by the least durable or slowest equipment, which may have a shorter operating time than other equipment. The minimum value of the operating time of each device divided by the production time is selected as the production line utilization rate, which can effectively reflect the impact of the least efficient equipment in the entire production process on the overall utilization rate of the production line.

[0052] It is important to know that during the operation of the production line, the equipment's downtime for maintenance and adjustment causes the equipment's operating time to be lower than the production line's operating time. If the equipment's operating time is close to or equal to the total operating time of the production line, the production line's downtime will be reduced to a minimum, which will help improve the utilization rate of the production line.

[0053] Similarly, the production line utilization rate of each production record of various products in the current management cycle is analyzed by referring to the resource consumption rate to obtain the production line utilization rate of various products in the current management cycle.

[0054] In a further preferred implementation of the above scheme, the production value coefficient of various products in the current management cycle is evaluated as follows: Substituting the resource consumption rate, production efficiency, and production line utilization rate of various products in the current management cycle into the evaluation formula The production value coefficients of various products in the current management cycle are obtained, where RC, PY, and PR represent the resource consumption rate, production efficiency, and production line utilization rate of the product in the current management cycle. From this formula, it can be seen that the smaller the resource consumption rate of the product in production, the higher the production efficiency and production line utilization rate, and the greater the production value.

[0055] The present invention evaluates the production value of products from three dimensions, namely resource consumption rate, production efficiency and production line utilization rate, based on the production records of the products. It can comprehensively understand and evaluate the efficiency and cost-effectiveness of production activities, provide multi-angle data evaluation support for production value, and help improve the accuracy and reliability of the evaluation results.

[0056] The product advantage grade classification module is used to classify the advantage grades of various products based on the sales value coefficients and production value coefficients of various products in the current management cycle. The specific classification is implemented as follows: the sales value coefficients and production value coefficients of various products in the current management cycle are weighted averaged and normalized to obtain the advantage degree of various products in the current management cycle.

[0057] In the above weighted average, the weight factors corresponding to the sales value coefficient and the production value coefficient can be set based on the company's strategic direction and market competition environment. Specifically, if the company emphasizes the production efficiency of its products, it may tend to give a higher weight to the production value; if the company focuses on market share and sales results, it may pay more attention to sales value. In a highly competitive market, sales value may be more critical, so the weight of sales value may need to be increased; in a relatively stable or specialized market, production efficiency and quality may bring more competitive advantages, so the weight of production value can be relatively high.

[0058] Further normalization calculation can substitute the weighted average calculation result into the normalization function for numerical limitation, which provides convenience for the subsequent advantage level classification.

[0059] Set the dominance level and determine the dominance range corresponding to each dominance level.

[0060] In the example implementation of the above scheme, since the superiority of various products in the current management cycle is obtained by normalization calculation, the value range of the superiority is between 0 and 1. Therefore, the superiority range corresponding to the superiority level can be determined according to the value range of the superiority. In a specific example, when three superiority levels are set, the superiority range corresponding to each superiority level can be (0.6, 1], (0.3, 0.6], [0, 0.3], in another example, when four superiority levels are set, the superiority range corresponding to each superiority level can be (0.75, 1], (0.5, 0.75], (0.25, 0.5], [0, 0.25]. It can be seen from this division that the more superiority levels are set, the more detailed the division between the superiority levels, and the more single the products falling into the same superiority level are. The number of superiority levels can be set according to the demand for detailed division of superiority levels.

[0061] The superiority of various products in the current management cycle is divided according to the superiority range corresponding to each superiority level to obtain the superiority level corresponding to various products.

[0062] The production schedule adjustment module is used to adjust the currently generated production schedule based on the advantage levels corresponding to various products. The specific adjustments are as follows: the order time corresponding to each production order is extracted from the currently generated production schedule for comparison, and production orders with similar order times are selected as concurrent production orders.

[0063] The ordering sequence of the production orders of the same period is extracted from the production order table, and the advantage sequence of the production orders of the same period is obtained from the advantage levels corresponding to various products based on the product types corresponding to the production orders of the same period.

[0064] The scheduling order of the production orders of the same period is compared with the advantage order. If the scheduling order is consistent with the advantage order, no scheduling adjustment is made. If they are inconsistent, the scheduling of the production orders of the same period is adjusted according to the advantage order.

[0065] It should be understood that when adjusting the production schedule according to the product's advantage level, the reason why orders of the same period are used as the adjustment object is that orders of the same period usually share the same production resources, including production equipment, human resources, etc. By adjusting the orders of the same period, these shared resources can be maximized to avoid waste of resources and inefficiency caused by frequent switching and adjustments. In addition, the adjustment of orders of the same period is easier to operate and manage than randomly selected orders. Production managers can handle related orders in the same time period more centrally to ensure that the implementation and effect monitoring of adjustments are more accurate and effective.

[0066] By comparing and adjusting the order of production orders of the same period with the order of product advantage, the present invention can more effectively utilize production resources, give priority to the production of products with a high advantage order, and achieve higher output and efficiency within a limited time, thereby maximizing the utilization rate and benefits of the production line.

[0067] The sales object adjustment module is used to determine key products and non-key products based on the advantage levels corresponding to various products, thereby determining the sales direction based on the market coverage, market demand and market share trend of the key products in the current management cycle, and at the same time identifying whether non-key products have the conditions for sales market conversion. If so, sales market conversion of non-key products is carried out.

[0068] In the optional implementation scheme of the above scheme, key products and non-key products can be determined specifically by defining critical advantage levels, and products falling within the level before the critical advantage level are regarded as key products, and other products are regarded as non-key products.

[0069] For example, when there are four advantage levels, the critical advantage level is defined as the second advantage level, then the products falling into the first and second advantage levels are classified as key products, and the products falling into the third and fourth advantage levels are classified as non-key products.

[0070] The present invention can highlight key sales targets by determining key products and non-key products, which is conducive to concentrating key sales resources on key products, optimizing sales strategies, and improving sales efficiency and effectiveness. For non-key products, it is possible to consider reducing resource investment or finding other sales strategies.

[0071] The above-mentioned sales strategy for key products is to determine the sales direction based on the market coverage, market demand and market share trend of key products in the current management cycle. The specific operations are as follows: Identify whether the market share trend of key products in the current management cycle shows a downward trend. This can be identified based on the positive and negative values ​​of the market share trend. If there is a trend that indicates that the key product's market share advantage has declined, it is judged that the sales direction of the key product needs to be adjusted.

[0072] The specific sales direction is determined as follows: compare the market demand and market coverage of key products in the current management cycle with those in the previous management cycle. If the market coverage of key products in the current management cycle is less than that in the previous management cycle, it indicates that the product sales network may be reduced or fail to effectively cover the potential market area. At this time, it is reasonable to choose to expand the sales area. The market coverage of products can be expanded by opening up new markets and increasing sales channels, thereby increasing sales opportunities and market share. If the market demand of key products in the current management cycle is less than that in the previous management cycle, it means that the attractiveness or demand of the product in the market has decreased. By determining to increase market demand as an adjustment to the sales direction, it means that it is necessary to re-stimulate consumers' willingness to buy through marketing, product innovation or pricing strategies to increase the market demand of products.

[0073] The present invention compares the market demand and market coverage of key products in the current management cycle with those in the previous management cycle, and determines the sales direction adjustment based on the comparison results. It can help enterprises accurately grasp market changes, realize targeted sales adjustments, avoid ineffective adjustments caused by blind adjustments, and help improve adjustment efficiency and effects, thereby optimizing resource allocation, enhancing market competitiveness, and improving sales performance and market share.

[0074] Furthermore, the sales strategy for non-key products is to identify whether non-key products have the conditions for sales market conversion. For details, please refer to the following process: non-key products and key products are analyzed for product similarity and sales target similarity, where product similarity specifically includes product raw material similarity and product production process similarity, and sales target similarity includes sales area similarity, sales group similarity, etc.

[0075] The product similarity and sales target similarity analysis results between non-key products and key products are compared with the similarity threshold set by the system. If the product similarity and sales target similarity analysis results both reach the similarity threshold, the non-key product is identified as having the conditions for sales market conversion.

[0076] The present invention converts the sales market of non-key products into the sales market of key products by converting the analysis results of non-key products and key products based on product similarity and sales target similarity, so that the sales resources and marketing forces of the enterprise can be effectively and quickly concentrated on the core products, greatly improving the sales efficiency and resource utilization. In addition, the sales market of non-key products is often scattered and fragmented, and different sales strategies and resource allocations may be required. Converting these markets into sales markets for key products can reduce market fragmentation, simplify sales management and execution, and improve the overall market coverage efficiency.

[0077] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.

A process-based production and marketing linkage management system for chemical industry as claimed in claim 1, characterized in that: The process of adjusting the currently generated production schedule is as follows: Extract the order time corresponding to each production order from the currently generated production schedule table for comparison, and select the production orders with similar order time as the production orders of the same period; Extract the order sequence of the production orders of the same period from the production order table, and obtain the advantage sequence of the production orders of the same period from the advantage levels corresponding to various products based on the product types corresponding to the production orders of the same period; The scheduling order of the production orders of the same period is compared with the advantage order. If the scheduling order is consistent with the advantage order, no scheduling adjustment is made. If they are inconsistent, the scheduling of the production orders of the same period is adjusted according to the advantage order.

9. A process-based production and marketing linkage management system for chemical industry as claimed in claim 1, characterized in that: The sales direction determined based on the market coverage, market demand and market share trend of key products in the current management cycle is implemented as follows: Identify whether the market share of key products in the current management cycle is showing a downward trend. If so, it is necessary to adjust the sales direction of key products; Compare the market demand and market coverage of key products in the current management cycle with those in the previous management cycle. If the market coverage of key products in the current management cycle is less than that of the previous management cycle, the sales direction is to expand the sales area; if the market demand of key products in the current management cycle is less than that of the previous management cycle, the sales direction is to increase market demand.

10. A process-based production and marketing linkage management system for chemical industry as claimed in claim 1, characterized in that: The identification of whether a non-key product has the conditions for sales market conversion is as follows: Conduct product similarity and sales target similarity analysis on non-key products and key products respectively; The product similarity and sales target similarity analysis results between non-key products and key products are compared with the similarity threshold set by the system. If the product similarity and sales target similarity analysis results both reach the similarity threshold, the non-key product is identified as having the conditions for sales market conversion.
