# Research on Flexible Traceability System of _Agaricus bisporus_ Supply Chain
## 4 Design of the System  
### Analysis of the Needs of Each Tracing Subject  
Addressing the issues of low query efficiency and the inability to accommodate the diverse information needs of different traceability stakeholders in the supply chain, we propose a multi-chain traceability model for _Agaricus bisporus_ tailored to these stakeholders' requirements. 1. Consumers assume a pivotal role as ultimate end-users within the _Agaricus bisporus_ supply chain. Their levels of awareness, attitudes, and willingness to invest in traceable _Agaricus bisporus_ serve as the primary impetus driving the advancement of the traceability system. Consequently, this exerts a substantial influence on the operational conduct of \begin{table}
\begin{tabular}{c c c c c c} \hline \hline
**Traceability of the** & **Cultivation** & **Storage** & **Process** & **Logistics** & **Sales** \\ \hline Consumers (public chain) & Product grade, cultivation environment, control information, harvesting time & Storage environment, storage time & Processing time, processing environment, quality quality information & Logistics environment, logistics information & Selling unit, shelf life, sales chain, license information \\ \hline Corporations (enterprise chain) & Variety information, harvest lot, harvest quantity & Inbound time, outbound time, stock level & Processing quantities, process information & Product grade, number of products & Batch information, sales quantity \\ \hline Regulator (regulatory chain) & Enterprise qualification, quality inspection report & Storage environment, investment testing report & Qualification information, quality inspection report & Logistics qualification & Sales environment information, qualification information \\ \hline \hline \end{tabular}

Table 1: Supply chain traceability data classification for traceability subjects. Enterprises  
Enterprises play a pivotal role in the _Agaricus bisporus_ supply chain, serving as the principal providers of goods, disseminators of information, financial resources, and credit, as well as connectors with consumer groups. They assume a central position in the supply chain, facilitating comprehensive information sharing within the traceability system. This capability empowers them to aggregate and distribute data across various stages, affording a more profound comprehension of the complete _Agaricus bisporus_ production process. Consequently, enterprises can refine their production processes and bolster the efficacy of supply chain management. Moreover, transparent information sharing enables enterprises to bolster their brand image. The traceability system functions as a catalyst for attaining meticulous management and quality control. By vigilantly overseeing the entire lifecycle of _Agaricus bisporus_, enterprises can expeditiously pinpoint and rectify production-related issues and effectively manage risks, thereby improving product quality and safety. This, in turn, elevates consumer satisfaction levels and fortifies the reputation of the enterprise. Enterprises are poised to institute a value delivery framework within the traceability system, accomplishing a spectrum of value delivery objectives, including information dissemination, brand fortification, quality assurance, and risk mitigation. Ultimately, this fosters the enhancement in core competitiveness and market powers for enterprises [22]. Regulatory authorities hold a pivotal role within the _Agaricus bisporus_ traceability system. Their primary responsibility is to oversee a range of crucial data and information, particularly those pertaining to potential food safety concerns within the _Agaricus bisporus_ supply chain. This encompasses scrutinizing the production qualifications of enterprises, examining quality inspection reports, and evaluating environmental data at various stages of production. As an authoritative third party, regulatory authorities conduct comprehensive oversight and audits across the various stages of the _Agaricus bisporus_ supply chain.
