# Risk Assessment in Supplier Selection for Intelligent Manufacturing Systems Based on PLS-SEM
## 3 Constructing IMSS Suppliers Risk Evaluation Model Based on PLS-SEM  
### Index Identification  
The specification conditions for intelligent manufacturing system solution suppliers (hereinafter referred to as the \"Specification Conditions\") clearly point out the need to strengthen IMSS suppliers management [26; 27], standardize supplier service processes and ensure service quality, and meet the needs of transformation and the upgrading of manufacturing enterprises. According to this specification, the basic information of IMSS suppliers and the information system can be divided into six risk dimensions, mainly including supplier qualification, system, core technology, service capability, project and information system solutions. The details are as follows:  
1. Supplier qualification (SQ). SQ requires the supplier to have good credit and public image, operate legally and in good faith, meet the safety production conditions specified in the relevant laws and regulations, national standards or industrial standards, and establish a perfect quality management system, environmental management system and information security management system, and the supplier shall operate effectively and pass the third-party certification. SQ is the most basic requirement for IMSS suppliers. 2. Supplier system (SS). The \"Specification Conditions\" emphasize that IMSS suppliers should establish a perfect project document management system, which should cover demand documents, project plans, design documents, implementation schemes, etc. ; at the same time, the document management system should have a perfect after-sales service system and strict system equipment management information system, equipped with special maintenance departments and professionals, provide users with corresponding technical consultation, technical training and maintenance services. 3. Supplier core technology (SCT). In the process of use, the value of core technology can be increased, with the characteristics of continuous growth and increasing returns. IMSS suppliers shall have core technology in key technical equipment, software, intelligent manufacturing complete equipment, the process and integration optimization of key parts. The core technology requires authorized patents related to intelligent manufacturing system integration technology or software copyright related to intelligent manufacturing. 4. Supplier service capability (SSC). The \"Specification Conditions\" points out that IMSS suppliers should have a professional consulting and planning team, be familiar with users' industry knowledge and technology, have project consulting and planning experience and personalized customization ability. The professional consulting and planning team needs to confirm the function, cycle and cost of user needs, carry out system integration and secondary development and implementation, have certain platform construction ability, and be able to provide corresponding services in collaborative design, big data analysis and other aspects, according to user needs. 5. Supplier project (SP). The project is the carrier to realize the enterprise development strategy. The mission, vision and strategic objectives of the enterprise need to be realized through successful projects. SP includes the number of docking projects, project investment amount, project satisfaction and project success rate. 6. Supplier information system solutions (SISS). The \"Specification Conditions\" point out that IMSS suppliers should have modular and standardized solutions so that the system solutions have the ability of replication and promotion. At the same time, according to the characteristics of the project, IMSS suppliers should have the ability of system customization for intelligent manufacturing equipment, such as intelligent sensing and control equipment and intelligent process equipment, and provide system safety emergency plans to ensure system safety.
