精读内容

在问题描述章节，作者描述了自己所研究问题的情况并进行了假设：1.由供应商、第三个物流服务商、零售商组成的三级冷链。2.第三方物流服务商负责生鲜品的保鲜和配送，决策碳减排水平，保鲜努力，冷链服务价格。3.供应商决策批发价格。4.零售商预测市场需求并决定零售价格。5.碳排放只存在第三方物流服务商运送过程。6.第三方物流服务商引入碳减排技术减少碳排放。

In the problem description section， the authors describe their research problem and make the following assumptions: 1. A three-tier cold chain consisting of suppliers， a third logistics service provider， and retailers. 2. The third logistics service provider is responsible for the preservation and distribution of fresh produce， and decides on the level of carbon emission reduction， the preservation effort， and the price of the cold chain service. 3. The supplier decides on the wholesale price. 4. The retailer predicts the market demand and decides on the retail price. 5. Carbon emissions only exist in the delivery process of the 3PL service provider. 6. The 3PL service provider introduces carbon reduction technology to reduce carbon emissions. 7.

决策图如下：

The decision diagram is shown below:

随后对文中使用的符号进行了提前说明：

This is followed by an advance description of the symbols used in the text:

紧接着构建了需求函数：

The demand function is constructed immediately after:

其含义为需求等于市场规模加上减碳带来的需求，加上保鲜带来的需求，最后减去价格。

接下来借鉴其他人研究并对碳减排和保鲜成本进行定义，并构建了生产过程单位产品碳排放函数：

The implication is that demand is equal to market size plus demand due to carbon reduction， plus demand due to preservation， and finally minus price.

Next， drawing on the research of others and defining the costs of carbon reduction and preservation， a carbon emission function per unit of product for the production process is constructed:

在数学模型章节，首先构造了分散决策下的供应链利润模型：

零售商利润模型：

In the mathematical modelling section， the supply chain profit model under decentralised decision-making is first constructed:

Retailer profit model:

其含义为销售价格减去批发价格乘以需求量。

供应商利润模型：

It means selling price minus wholesale price multiplied by quantity demanded.

Supplier profit model:

其含义为批发价格减去物流服务价格减去单位产品生产成本，乘以需求量。

第三方物流服务商利润函数：

The meaning is the wholesale price minus the price of logistics services minus the production cost per unit of product， multiplied by the quantity demanded.

Third party logistics service provider profit function:

其含义为物流价格减去引入碳减排技术成本减去保鲜成本，乘以需求量，最后减去碳排放成本。

The implication is that the logistics price minus the cost of introducing carbon abatement technologies minus the cost of preservation， multiplied by the demand and finally minus the cost of carbon emissions.

知识补充

文中提到引入碳减排技术，那么碳减排技术有哪些呢？

碳减排技术是指通过减少或阻止二氧化碳（CO2）等温室气体的排放来降低人类活动对气候变化的影响。以下是一些常见的碳减排技术：

能源效率提升：通过改进生产和使用能源的效率，减少能源消耗，从而降低碳排放。

可再生能源利用：推广利用太阳能、风能、水能、地热能等可再生能源，减少对化石燃料的依赖，从而减少碳排放。

碳捕捉与封存（CCS）：将二氧化碳捕捉并储存起来，以防止其释放到大气中。

核能发电：利用核能发电解决能源需求，因为核能发电不会产生二氧化碳排放。

碳交易与碳市场：建立碳排放权交易制度，通过发放和交易碳排放权来鼓励企业减少排放。

生态恢复与碳汇：通过植树造林、湿地保护等手段增加植被覆盖和保护自然生态系统，将大气中的二氧化碳吸收并固定在土壤或植物中。

可深度处理的废物管理：采用高效、环保的废物处理技术，最大限度地减少废物的产生和排放。

电动化和氢能：推广电动汽车、氢燃料电池等低碳交通方式，减少车辆燃料的燃烧排放。

The article mentions the introduction of carbon reduction technologies.

Carbon reduction technology refers to reducing the impact of human activities on climate change by reducing or stopping the emission of greenhouse gases such as carbon dioxide (CO2). Here are some common carbon reduction technologies:

Energy Efficiency Enhancement: Reduce energy consumption by improving the efficiency of production and use of energy， thereby reducing carbon emissions.

Renewable Energy Utilisation: Promoting the use of renewable energy sources such as solar， wind， hydro and geothermal energy to reduce reliance on fossil fuels， thereby reducing carbon emissions.

Carbon Capture and Storage (CCS): Capturing and storing carbon dioxide to prevent its release into the atmosphere.

Nuclear Power Generation (NPG): Using nuclear power generation to solve energy needs as it does not produce carbon dioxide emissions.

Carbon Trading and Carbon Markets: Establishing a carbon trading system to encourage companies to reduce emissions by issuing and trading carbon credits.

Ecological Restoration and Carbon Sinks: Increase vegetation cover and protect natural ecosystems by means of afforestation and wetland protection to absorb and fix atmospheric carbon dioxide in the soil or plants.

Deeply treatable waste management: Adopt efficient and environmentally friendly waste treatment technologies to minimise waste generation and emissions.

Electrification and hydrogen energy: Promote low-carbon modes of transport such as electric vehicles and hydrogen fuel cells to reduce emissions from vehicle fuel combustion.
