Introduction <br> <br> many companies process design system is built on the basis of fixed manufacturing resources, difficult to adapt to changes in the dynamic characteristics of manufacturing resources at any time, while in the traditional manufacturing model, enterprise manufacturing resource model is based on the individual Phases, departments, and computer application subsystems are developed to meet the needs of manufacturing resource information, and establish independent manufacturing resource models and databases, resulting in inconsistent manufacturing resources, large amount of data redundancy, and inability to effectively support process design and other Synergies between production activities. To this end, this paper studies the manufacturing resource management that supports collaborative process design, proposes to build a manufacturing resource unified management platform (MRIMP), realizes the unified management of manufacturing resources, and realizes the unification and sharing of manufacturing resources in various information systems. Effectively improve the guidance of process design. 1.2 MRIMP Architecture Supporting Collaborative Process Design In the enterprise, there are many departments that use manufacturing resource information. From the company management planning department to the design department to the workshop manufacturing department, manufacturing resources are inseparable. As a unified management platform for manufacturing resources, it will inevitably transmit and coordinate information with many information systems. To this end, this paper proposes an architecture to solve the problem of manufacturing resource information shared between MRIMP and other application systems, as shown in Figure 2. Show. Next page
1 MRIMP system design supporting collaborative process design 1.1 Manufacturing resource modeling supporting collaborative process design Enterprise manufacturing resources are the basis of process design and are closely related to process design. As a unified platform for manufacturing resources, MRIMP not only supports the requirements of collaborative process design for real-time process information and status information of manufacturing resources, but also supports the requirements of other design and production activities for manufacturing resources, and provides corresponding manufacturing resource views to personnel of various departments. Relevant personnel collaborate on manufacturing resources and coordinate scheduling, which has the following requirements for modeling MRIMP manufacturing resources that support collaborative process design:
a. Support multi-view features of manufacturing resources. As a unified management platform for manufacturing resources, different requirements of manufacturing resources for each application system must be met, that is, different resource views are formed according to different system requirements.
b. Ensure consistency of manufacturing resource information. Manufacturing resources are throughout the lifecycle of a product, and it is important to ensure that manufacturing resources are consistent and unique across applications.
c. Support the dynamics of manufacturing resource information. Application systems such as CAPP have high requirements for real-time dynamic information of manufacturing resources, and need to know dynamic information such as manufacturing resource usage load and usage status.
Aiming at the modeling requirements of manufacturing resources, this paper designs a manufacturing resource model that supports collaborative process design, which provides powerful support for collaborative process design. The model is constructed with object-oriented ideas, and analyzes and summarizes various manufacturing resource objects. We divide the manufacturing resource object attributes into static attributes and dynamic attributes, and consider the manufacturing resource parameters into the following four aspects from the perspective of multi-view in the manufacturing resource model to support the product life cycle:
a. Management information of resources. It mainly includes the number, name, affiliation, manufacturing unit, etc. of the resource.
b. Technical parameters for the use of resources. Describe the various supporting technical parameters when using the resource, such as machining time, feed rate, cutting parameters, etc.
c. Resource capability information. Mainly refers to the scope of use of resources. Such as the machining accuracy of the lathe.
d. Status information of resources, including resource completion rate, usage load rate, current status, maintenance history record, etc.
Taking a lathe as an example, the model is shown in Figure 1. 
Figure 1 Description of the machine information model
Support system layer: From the aspects of system data source, data management and security, this layer includes tooling design system, MES system, process control system (ProcessoCntrolsystem, PCS), ERP system and database management system. The tooling design system, MES system and PSC system provide specific manufacturing resource information for MRIMP, and the database management system provides a safe and reliable management mechanism for MRIMP.
Database layer: mainly includes various manufacturing resource data used in the whole life cycle of the product, such as equipment, tooling and other resource data. Since some manufacturing resources are only used in process design, there is no need to manage MRIMP. For example, the terminology library can be directly managed by the CAPP system.
Resource management: It is mainly to comprehensively manage manufacturing resources, including resource model management, resource integration management and platform system management (ie, various usage rights and security management of the system).
Resource Application System Layer: Informatization systems that include manufacturing resources throughout the lifecycle, such as CAPP systems, ERP systems, CAM systems, and CAQ systems.
User interface layer: mainly involves the user's interactive query and modification of process resources, and feedback of information, etc., providing a friendly human-computer interaction interface for different needs.
The entire application system should be based on computer networks and distributed databases. All data is centrally organized and managed on the system server. It is completely network-based and fully supports collaborative process design. Firstly, MIRMP adopts object-oriented dynamic unified resource modeling to meet the requirements of collaborative process design for multi-view of manufacturing resources. Secondly, MIRMP implements unified management of manufacturing resources, which solves the inconsistency and ambiguity of manufacturing resources in various information systems. The problem is to improve the efficiency of collaborative process design. At the same time, MRIMP provides real-time manufacturing resource information through MES and CPS systems to meet the real-time information of collaborative process design and manufacturing resources. MRIMP provides coordinated process resource scheduling and configuration functions that support collaborative process design. Collaborative process design is optimized.
