The AHP-entropy weight method was used to calculate demand priorities, and modular combination parameters were generated through a CGAN-dynamic rule hybrid model, which was then dynamically updated using IoT sensors.
It achieves a furniture space utilization rate of over 85%, significantly improves design efficiency, deeply satisfies personalized needs, balances economy and sustainability, adapts to different apartment types and budgets, and reduces construction rework rate.

TECHNICAL FIELD
[0001] The present application relates to the technical field of modular furniture design, and particularly relates to an AI-driven affordable housing furniture modular combination parameter generation method. BACKGROUND
[0002] At present, the house type of affordable housing is mainly small and medium-sized (main area 40-60m 2 ), the space layout is compact (such as the average face width of the living room is only 2.5-3m, and the net depth of the bedroom is less than 3m), and the user group structure is diverse (including newly married families, elderly people living alone, disabled families, etc.), the space adaptability, function complexity and cost controllability of furniture are significantly higher than those of ordinary commercial housing. At the same time, the existing furniture is mostly standardized mass production products (such as fixed size wardrobe, non-expandable dining table), or is designed only for ordinary families, which is difficult to meet the special needs of high utilization of small space, low budget and high quality, and multi-scene adaptation of affordable housing, resulting in additional self-reform of users (reform rate more than 60%), or space waste and function redundancy (such as large size sofa occupying 30% of the living room space) due to the mismatch between furniture and space / demands, which seriously affects the living experience.
[0003] From the user demand dimension, there are three core pain points of affordable housing users: first, space anxiety, the furniture size does not match the space in small house type (such as traditional 600mm deep bookcase leads to narrow movement line in bedroom), the furniture needs to have the ability of expansion, folding and modular combination; second, cost sensitivity, the user's per capita furniture expenditure is generally less than 2000 yuan (only 1 / 3 of that of commercial housing users), the cost of materials and manufacturing needs to be controlled, while the durability (expected service life ≥8 years) is also considered; third, diverse needs, the elderly family needs barrier-free handrails and lightweight operation, the family of three needs child safety protection and more storage space, and traditional standardized furniture cannot meet such individualized needs.
[0004] The existing demand modeling method mainly relies on questionnaire survey + expert judgment, which has the following shortcomings in the affordable housing scene: 1. Insufficient ability to capture implicit needs: traditional research (such as paper questionnaire, offline interview) can only obtain explicit needs such as "need storage" and "need dining table", and cannot identify the implicit demands of affordable housing users - for example, the "expandable size demand" behind the user feedback "the space is too small" and the "barrier-free handrail demand" behind the "difficulty in getting up" of the elderly. Although existing research has introduced Kano model, user portrait and other methods, it has not combined with emotional tendency analysis in the affordable housing scene, resulting in less than 50% accuracy rate of implicit demand capture.
[0005] 2. Large subjective bias in demand priority calculation: existing demand weight determination mostly uses a single method: either relying on expert subjective scoring of AHP (analytic hierarchy process), or relying on objective data dispersion calculation of entropy weight method. Among them, the single AHP method is easily affected by the experience of experts (such as setting the "aesthetics" weight to 0.2, far exceeding the actual concern of 0.05 of low-income housing users), and the weight error can reach 15%; the single entropy weight method is only based on data dispersion, and cannot reflect the special appeal of "space adaptation priority over aesthetics" of low-income housing. SUMMARY
[0006] The purpose of the present application is to provide an artificial intelligence driven low-income housing furniture modular combination parameter generation method to solve the above technical problems.
[0007] To achieve the above purpose, the present application provides an artificial intelligence driven low-income housing furniture modular combination parameter generation method, comprising the following steps: S1, combine the low-income housing house type database, user portrait, online questionnaire and network text to construct the original demand data set, calculate the demand priority weight based on AHP-entropy weight method, and obtain the function demand list and function demand weight by using QFD function demand mapping; S2, based on the function demand list and function demand weight output by S1, combined with the low-income housing space characteristic division, through the mortise and tenon parameter optimization, sustainable material selection, finite element strength verification and general interface design, the modular unit parameter library of structure-material-interface is constructed; S3, based on the modular unit parameter library constructed in S2, combined with the low-income housing target space parameters, construct the labeled data set and train the CGAN-dynamic rule hybrid model, generate the preliminary combination parameter scheme, and then screen the multi-level adaptive scheme through expert semantic differentiation evaluation; S4, based on the multi-level adaptive scheme output by S3, combined with the function demand weight of S1 to construct the space-strength-economy-sustainability optimization model, and determine the optimal combination parameter scheme through NSGA-II algorithm optimization and AD axiom design verification; S5, based on the optimal combination parameter scheme output by S4 to generate a standardized executable parameter file, deploy IoT sensors to collect furniture usage state data, train parameter adjustment model and dynamically update the modular unit parameter library described in step S2.
[0008] Therefore, the present application adopts the above-mentioned artificial intelligence driven low-income housing furniture modular combination parameter generation method, which has the beneficial effects of: 1. Precise improvement of space adaptability: based on the dynamic condition vector integrating low-income housing space size, layout constraints and other parameters, combined with multi-objective optimization algorithm, the furniture combination space utilization rate is improved to more than 85%, avoiding problems such as size overrun and layout conflict.
[0009] 2. Significantly improved generation efficiency: Automatically generate combination parameters with CGAN-dynamic rule hybrid model, replace traditional manual repeated adjustment process, compress single-family furniture parameter design period from several days to hours, greatly reduce design cost; 3. Deeply meet personalized needs: Quantify user space adaptation, economic cost, and needs weight of elderly and young children through AHP-entropy weight method, generate scheme to accurately match different family structure and special demands, and improve living experience; 4. Balance between economy and sustainability: Multi-objective optimization considers material cost, recyclability and environmental protection requirements, uses standardized modules to reduce production and maintenance cost, and increase recyclable material ratio, which meets the low-carbon economic demand of indemnificatory housing; 5. Dynamic iteration of parameter system: Continuously update modular parameter library through parameter adjustment formula based on IoT collected usage data, adapt to actual usage scenarios such as furniture wear and deformation, and prolong product life cycle; 6. Consideration of universality and compliance: Compatible with different house types, budgets and policy specifications, the generated scheme automatically meets the requirements of structural safety, environmental protection standards, etc., reduces construction rework rate, and adapts to the scenarios of indemnificatory housing projects in multiple regions.
