Dear you，

this is the LearingYard Academy!

Today， the editors bring you the problem description and assumptions and decentralised decision-making model of the optimal decision-making and coordination of a tertiary cold chain for fresh produce considering preservation efforts and carbon reduction efforts.

Welcome to visit!

本期推文將本通過思維導圖，精讀內容，知識補充三個板塊，展示期刊論文《考慮產運環節碳排放的生鮮低碳供應鏈運營決策》問題描述與假設和分散決策模型，請讀者跟著小編一起來學習吧！

This issue of the tweet will be this through the mind map， intensive reading content， knowledge supplement three panels， show the journal paper "Considering the carbon emissions of production and transport links of fresh low-carbon supply chain operation decision-making" problem description and assumptions and decentralised decision-making model， readers are invited to follow the editor to learn it!

精讀內容

在問題描述章節，作者描述了自己所研究問題的情況并進行了假設：1.由供應商、第三個物流服務商、零售商組成的三級冷鏈。2.第三方物流服務商負責生鮮品的保鮮和配送，決策碳減排水平，保鮮努力，冷鏈服務價格。3.供應商決策批發價格。4.零售商預測市場需求并決定零售價格。5.碳排放只存在第三方物流服務商運送過程。6.第三方物流服務商引入碳減排技術減少碳排放。

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.

決策圖如下：

The decision diagram is shown below:

隨后對文中使用的符號進行了提前說明：

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

緊接著構建了需求函數：

The demand function is constructed immediately after:

其含義為需求等于市場規模加上減碳帶來的需求，加上保鮮帶來的需求，最后減去價格。

接下來借鑒其他人研究并對碳減排和保鮮成本進行定義，并構建了生產過程單位產品碳排放函數：

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:

在數學模型章節，首先構造了分散決策下的供應鏈利潤模型：

零售商利潤模型：

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

Retailer profit model:

其含義為銷售價格減去批發價格乘以需求量。

供應商利潤模型：

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

Supplier profit model:

其含義為批發價格減去物流服務價格減去單位產品生產成本，乘以需求量。

第三方物流服務商利潤函數：

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:

其含義為物流價格減去引入碳減排技術成本減去保鮮成本，乘以需求量，最后減去碳排放成本。

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.

知識補充

文中提到引入碳減排技術，那么碳減排技術有哪些呢？

碳減排技術是指通過減少或阻止二氧化碳（CO2）等溫室氣體的排放來降低人類活動對氣候變化的影響。以下是一些常見的碳減排技術：

能源效率提升：通過改進生產和使用能源的效率，減少能源消耗，從而降低碳排放。

可再生能源利用：推廣利用太陽能、風能、水能、地熱能等可再生能源，減少對化石燃料的依賴，從而減少碳排放。

碳捕捉與封存（CCS）：將二氧化碳捕捉并儲存起來，以防止其釋放到大氣中。

核能發電：利用核能發電解決能源需求，因為核能發電不會產生二氧化碳排放。

碳交易與碳市場：建立碳排放權交易制度，通過發放和交易碳排放權來鼓勵企業減少排放。

生態恢復與碳匯：通過植樹造林、濕地保護等手段增加植被覆蓋和保護自然生態系統，將大氣中的二氧化碳吸收并固定在土壤或植物中。

可深度處理的廢物管理：采用高效、環保的廢物處理技術，最大限度地減少廢物的產生和排放。

電動化和氫能：推廣電動汽車、氫燃料電池等低碳交通方式，減少車輛燃料的燃燒排放。

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.
