Robots vs. Conveyors: A Cage Match in the Factory! (Spoiler: It's Complicated)
This paper compares the use of autonomous mobile robots (AMRs) in production networks with traditional conveyor-based lines in process industries. The authors develop an analytical model and conduct a parametric analysis to identify conditions under which AMR networks offer higher throughput, flexibility, and cost advantages, concluding that AMR implementation can be beneficial for high product mix scenarios, particularly with decreasing AMR costs and increased shifts.
Possible Conflicts of Interest
The research is partially supported by a research project (Digi-Mat) and a grant (MAIA-H2020-MSCARISE). While these do not appear to present direct conflicts, the source of funding should be noted for transparency.
Identified Weaknesses
Simplified Setup Assumptions
The model assumes synchronous operation during setup, meaning that setup times are long enough to cause blocking or starving of machines. This simplifies reality and may not reflect the true dynamics of many production systems where smaller setups or buffer management strategies can mitigate these effects.
Overly Optimistic Micro-Breakdown Assumption
Micro-breakdowns are mentioned but assumed not to impact blocking or starving. This is a strong assumption, as micro-breakdowns, while individually short, can accumulate and significantly affect line throughput, particularly in balanced lines.
Inaccurate Cost Assessment
The cost of the inter-operational buffer is deemed negligible. While potentially true for short transfer lines, this can be a significant cost factor for larger systems, especially those requiring complex conveyor configurations.
Limited Scope of Comparison
The model primarily focuses on comparing traditional balanced lines with AMR networks. This omits other line balancing approaches or hybrid models that could offer cost-effective or performance advantages. A broader comparative analysis would strengthen the conclusions.
Oversimplification of AMR Routing
The paper acknowledges using predetermined AMR paths for simplification. This is a major limitation, as dynamic routing is one of the key advantages of AMRs. Fixed routes diminish the flexibility benefits being touted and can lead to suboptimal throughput.
Rating Explanation
The paper presents a relevant topic and develops a model to compare AMR networks with traditional production lines. However, several simplifying assumptions, particularly regarding AMR routing and setup dynamics, limit the model's realism and practical applicability. The limited scope of comparison and potential cost inaccuracies further reduce the strength of the conclusions. Overall, it is an average study with some interesting ideas but significant limitations.
