“Qin Xueku Lian (67): Intensive reading of the master's thesis "Research on closed-loop supply chain decision-making considering the two-way fairness concerns of the original manufacturer" model assumptions and parameter descriptions”
Welcome to your visit.

一、思维导图（Mind mapping）

本期推文带来该论文的模型假设及参数说明部分的精读分享，该部分是第3章“公平中性下的供应链决策研究”的核心基础，通过假设简化现实与参数量化变量，为后续模型构建与求解提供清晰逻辑前提。

This issue of tweets brings a detailed reading and sharing of the model assumptions and parameter descriptions of the paper. This part is the core foundation of Chapter 3, "Research on Supply Chain Decision-making under Fairness and Neutrality". By simplifying reality and quantifying variables through assumptions it provides a clear logical premise for subsequent model construction and solution.

二、精读内容（Intensive reading content）

（一）模型相关假设说明（Description of model-related assumptions）

以下6项假设均围绕“剔除干扰、明确边界与确保可解”展开，既贴合闭环供应链实践，又为研究聚焦核心变量提供保障：

The following six hypotheses are all centered around "eliminating interference, defining boundaries, and ensuring solvability." They are consistent with closed-loop supply chain practices and ensure that the research focuses on core variables:

1.回收成本整合假设（Recovery cost integration assumptions）

现实中废旧产品回收存在数量波动、质量差异、费用不固定等不确定性，为避免模型复杂化，将这些回收相关的不确定性与费用统一纳入再制造生产成本。

In reality, there are uncertainties in the recycling of waste products, such as quantity fluctuations, quality differences, and non-fixed costs. To avoid complicating the model, these recycling-related uncertainties and costs are uniformly incorporated into the remanufacturing production costs.

此假设通过“降维”规避非核心变量干扰，使研究无需纠结回收环节细节，更聚焦“供应链决策”核心，同时简化后续利润函数与需求函数推导。

This hypothesis avoids interference from non-core variables through "dimensionality reduction", so that the research does not need to worry about the details of the recycling process, but focuses more on the core of "supply chain decision-making", while simplifying the subsequent derivation of profit function and demand function.

2.再制造成本与盈利约束假设（Remanufacturing cost and profit constraint assumptions）

结合企业实践，再制造产品成本低于新产品，且第三方再制造商因专注再制造，成本比原制造商更低；同时明确了第三方需在缴纳专利许可费后仍有盈利空间。

Based on corporate practices, the cost of remanufactured products is lower than that of new products, and third-party remanufacturers have lower costs than original manufacturers because they focus on remanufacturing; at the same time, it is clarified that third parties must still have profit margins after paying patent licensing fees.

该假设确立了“新产品、原制造商再制造产品与第三方再制造产品”的成本层级，为后续定价差异、需求分配提供逻辑基础，也确保了“多主体共存”的混合再制造场景合理成立。

This assumption establishes the cost hierarchy of "new products, products remanufactured by original manufacturers, and products remanufactured by third parties", provides a logical basis for subsequent pricing differences and demand allocation, and ensures the reasonable establishment of the "multi-subject coexistence" hybrid remanufacturing scenario.

3.渠道定价与盈利边界假设（Channel pricing and profit margin hypothesis）

明确各渠道定价机制：新产品经原制造商批发给零售商再零售，再制造产品由原制造商与第三方进行线上直销；同时设定定价需高于成本，保证各主体盈利动机。

Clarify the pricing mechanism for each channel: new products are wholesaled by the original manufacturer to retailers for retail sale, and remanufactured products are sold directly online by the original manufacturer and third parties; at the same time, prices must be set higher than costs to ensure the profit motivation of each entity.

此假设贴合了双渠道运营现实，既界定了各产品定价下限避免负利润，又清晰区分传统零售与线上直销的定价逻辑，为后续对比不同渠道决策效果提供依据。

This assumption fits the reality of dual-channel operations. It not only defines the lower limit of product pricing to avoid negative profits, but also clearly distinguishes the pricing logic of traditional retail and online direct sales, providing a basis for subsequent comparison of the decision-making effects of different channels.

4.产品替代与消费者偏好假设（Product substitution and consumer preference hypothesis）

假设再制造产品与新产品功能质量相近可以替代，但消费者对三者支付意愿不同（新产品最高，原制造商再制造产品次之，第三方再制造产品最低），并基于效用选择购买产品。

It is assumed that remanufactured products and new products have similar functions and quality and can be used as substitutes, but consumers have different willingness to pay for the three (new products are the highest, remanufactured products by the original manufacturer are the second, and remanufactured products by third parties are the lowest), and they choose to purchase products based on utility.

该假设是需求分析的核心，将消费者偏好差异转化为可推导的需求逻辑，为后续计算不同产品销量、分析定价对需求的影响提供关键支撑。

This hypothesis is the core of demand analysis, which transforms differences in consumer preferences into derivable demand logic, providing key support for subsequent calculations of sales of different products and analysis of the impact of pricing on demand.

5.单时期决策假设（Single-period decision assumption）

仅考虑某一固定周期内的决策，不涉及多个时期库存、跨期需求波动等问题。此假设简化时间维度干扰，使模型聚焦“静态决策下的均衡解对比”，降低求解难度，也为后续与“双向公平关切决策”对比奠定简洁基准。

This assumption considers only decisions within a fixed period, ignoring issues such as multi-period inventory and inter-period demand fluctuations. This reduces interference from the time dimension, allowing the model to focus on comparing equilibrium solutions under static decision-making, reducing the difficulty of solving the problem and establishing a concise benchmark for subsequent comparisons with "two-way fairness concern decisions."

6.主体公平中性假设（Subjective fairness neutrality assumption）

假设零售商与第三方再制造商仅追求利润最大化，无公平关切行为。该假设确立“公平中性”基准场景，排除其他主体行为偏好干扰，使集中决策与分散决策的对比更纯粹，清晰凸显“决策模式”对结果的影响，为后续引入原制造商公平关切提供参照。

Assuming retailers and third-party remanufacturers pursue profit maximization solely and lack fairness concerns, this assumption establishes a "fair and neutral" baseline scenario, eliminating interference from other actors' behavioral preferences. This allows for a more holistic comparison between centralized and decentralized decision-making, clearly highlighting the impact of the "decision-making model" on outcomes and providing a reference for the subsequent introduction of fairness concerns from original manufacturers.

（二）模型相关参数说明（Description of model-related parameters）

参数通过分类定义，将供应链的核心要素转化为可计算指标，涵盖6类关键变量，为模型求解与结果评估提供工具：

Parameters are defined by categories, transforming the core elements of the supply chain into computable indicators. They cover six key variables and provide tools for model solving and result evaluation:

1.成本类参数（Cost parameters）

界定新产品、原制造商与第三方再制造产品的生产与再制造成本，是定价决策的基础，成本差异直接决定各产品定价下限与利润空间，影响企业定价策略。

Defining the production and remanufacturing costs of new products, original manufacturers, and third-party remanufactured products is the basis for pricing decisions. Cost differences directly determine the lower limit of pricing and profit margins for each product, and affect the company's pricing strategy.

2.消费者偏好类参数（Consumer preference parameters）

量化消费者对三种产品的支付意愿，包括消费者对新产品、原制造商再制造产品、第三方再制造产品的支付意愿系数，是需求分配的关键，偏好差异决定消费者购买选择，进而影响各产品销量与企业利润。

Quantifying consumers' willingness to pay for three types of products, including the willingness to pay coefficients for new products, products remanufactured by original manufacturers, and products remanufactured by third parties, is the key to demand allocation. Differences in preferences determine consumers' purchasing choices, which in turn affect product sales and corporate profits.

3.消费者偏好类参数（Consumer preference parameters）

包括消费者购买新产品、原制造商再制造产品、第三方再制造产品的效用。效用函数是推导需求函数的关键桥梁，通过比较不同产品的效用，可确定消费者的购买选择，进而得到价格与需求量的对应关系，为后续求解均衡定价提供依据。

This includes the utility of consumers purchasing new products, products remanufactured by the original manufacturer, and products remanufactured by third parties. The utility function is a key bridge in deriving the demand function. By comparing the utility of different products, consumers' purchasing choices can be determined, and the corresponding relationship between price and demand can be obtained, providing a basis for subsequent equilibrium pricing solutions.

4.价格类参数（Price parameters）

包括新产品的批发价与零售价，原制造商再制造产品的直销价，第三方再制造产品的直销价，以及第三方再制造商缴纳的专利许可费。这些参数是供应链决策的核心输出，参数的取值直接决定各主体的利润与供应链效率。

These parameters include the wholesale and retail prices of new products, the direct sales price of remanufactured products by the original manufacturer, the direct sales price of remanufactured products by third parties, and the patent licensing fees paid by third-party remanufacturers. These parameters are the core outputs of supply chain decision-making, and their values directly determine the profits of each entity and the efficiency of the supply chain.

5.销量类参数（Sales volume parameters）

包括新产品、原制造商再制造产品、第三方再制造产品的销售量，销售量由需求函数推导得出，是利润计算的关键变量，利润等于价格与成本差乘以销售量，因此销售量的分配直接影响原制造商、零售商、第三方再制造商的盈利水平，也是对比集中决策与分散决策需求优化效果的核心指标。

Including the sales volume of new products, products remanufactured by original manufacturers, and products remanufactured by third parties. Sales volume is derived from the demand function and is the key variable in profit calculation. Profit equals the difference between the price and the cost, multiplied by the sales volume. Therefore, the distribution of sales volume directly affects the profitability of original manufacturers, retailers, and third-party remanufacturers. It is also the core indicator for comparing the demand optimization effects of centralized decision-making and decentralized decision-making.

6.绩效类参数（Performance parameters）

包括原制造商利润、零售商利润与第三方再制造商利润，以及供应链系统消费者剩余与社会福利。这类参数是研究结论的核心评价标准，通过对比不同决策模式下的利润、消费者剩余与社会福利，可判断哪种决策更优，也是后续设计协调契约的依据。

These parameters include the profit of the original manufacturer, the profit of the retailer, and the profit of the third-party remanufacturer, as well as the consumer surplus and social welfare of the supply chain system. These parameters are the core evaluation criteria for the research conclusions. By comparing the profit, consumer surplus, and social welfare under different decision-making models, we can determine which decision is more optimal and also form the basis for the subsequent design of coordination contracts.

该部分通过假设定边界，参数搭工具，将复杂的闭环供应链实践转化为可量化的理论模型，既确保研究不脱离现实逻辑，又为后续集中决策、分散决策的模型构建、求解与对比提供严谨前提。

This section transforms complex closed-loop supply chain practices into quantifiable theoretical models by setting boundaries through assumptions and building tools with parameters. This ensures that the research adheres to realistic logic and provides a rigorous premise for the subsequent construction, solution, and comparison of centralized and decentralized decision-making models.
