Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional monolithic MES systems are used, then centralized control and management is achieved, but the system cannot handle distributed production environments and decentralized decision-making requirements
Solution Approach 1:
The patent divides the monolithic MES system into multiple independent functional modules distributed across different locations. Each module can autonomously make decisions within its scope while contributing to global objectives, enabling the system to handle distributed production environments effectively.
Solution Approach 2:
The patent introduces a hierarchical dimension to the system architecture, with local decision-making modules at the lower level and global coordination at the upper level. This multi-level structure allows decentralized operations while maintaining overall system coherence and adaptability to distributed environments.
2Productivity
If decentralized autonomous functionalities are implemented, then local decision-making efficiency is improved, but coordination and communication overhead increases
Solution Approach 1:
The patent establishes predefined negotiation protocols and communication frameworks in advance, allowing autonomous modules to interact efficiently without ad-hoc coordination overhead. The standardized interfaces and procedures enable rapid local decision-making while minimizing communication time.
3Adaptability or versatility
If distributed order management is implemented, then resource optimization across multiple locations is achieved, but system complexity and coordination difficulty increase
Solution Approach 1:
The patent creates universal negotiation protocols and standardized interfaces that enable different distributed modules to interact through common rules. This multi-functional framework handles various coordination scenarios (order management, resource allocation, scheduling) through a unified approach, reducing overall system complexity despite distributed operations.

AI summary
A negotiation-based method and system for managing manufacturing execution system (MES) orders within a structure of distributed systems that include at least one ordering system and one or several executing systems ES. The method includes the steps of: a) creating an order for a service, the order having at least one negotiable requirement; b) distributing the order to one or several ES; c) evaluating the order by each ES and automatically determining whether the order is acceptable without negotiating or generating an offer for the service to launch a negotiation process wherein said OS and ES exchange offers and counteroffers until an agreement is reached or the offer refused; d) if a least one of the ES accepts the order, the OS sends a refusal to offers received from another ES; if no ES accepts the order, the OS starts a negotiation process for the negotiable requirement with each ES.
