Operation Serialization in Parallel CAx Workflows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-user computer-aided technologies (CAx) environments, the intermixing of operation execution orders can lead to errors or failures due to simultaneous execution of operations by multiple users, causing chaos and reducing productivity.
Innovation Solution
A method that monitors the operational state of a CAx client processor, queues remote operations when the processor is busy with local operations, and executes them when the processor becomes idle, ensuring serialized operation execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple CAx clients execute operations simultaneously in a multi-user environment, then collaboration efficiency is improved, but operation execution order becomes intermixed causing errors or failures
Solution Approach 1:
The patent introduces a server as an intermediary between multiple CAx clients. The server receives operations from clients, serializes them in a queue, and distributes them sequentially to target clients for execution. This mediator architecture enables multiple clients to collaborate simultaneously while ensuring operations are executed in a controlled, non-intermixed manner, thus maintaining both productivity and reliability.
2Reliability
If remote operations are queued when processor is busy, then data integrity is maintained, but operation execution time increases
Solution Approach 1:
The patent implements preliminary action by queuing remote operations in advance when the processor is busy, rather than waiting until the processor is free. The queue stores operations in the order they are received, and the processor executes them sequentially as they become available. This preliminary queuing mechanism maintains data integrity by preventing simultaneous execution conflicts while minimizing delays through immediate acceptance and ordered processing of operations.

AI summary
A method for multi-user CAx editing includes monitoring an operational state of a processor of a first CAx client, receiving, at a communication filter of the first CAx client, a first remote operation to be executed by the first CAx client in a CAx environment, populating the first remote operation to a queue formed in a memory structure in response to a determination that the operational state of the processor of the first CAx client is executing a local operation when the first remote operation is received, and executing the first remote operation in the CAx environment on the first CAx client in response to a determination that the operational state of the processor of the first CAx client is idle. A computer program product such as a computer readable medium and a computer system corresponding to the above method are also disclosed herein.
