gnn_scheduler's Issues

Phase 1: Literature Review

First, we need to define what we will do in this project. This is why a good literature review would be very beneficial before writing code. This literature review should be documented in the thesis and should answer the following questions:

  • [Introduction?]: Why would anyone use ML to solve the JSP instead of other traditional methods such as MIP?
  • [State of the art?]: What are the advantages of representing the problem as a graph instead of other modalities?
  • [State of the art]: What is the best graph representation for the problem?
  • [???]: What are the characteristics of the best GNN architectures in terms of representation and generalization?
  • [???]: What are the pros and cons of using SL versus RL in this context?

Other things that should be explained in this phase (base knowledge):

  • [Introduction?]: What are GNNs?
  • What the Job Shop Scheduling Problem is about.
  • What the role of dispatching rules is.
  • Decide which experiments to conduct and when.

Deliverables

The following sections of the main body of the thesis should be written at the end of this phase:

  • Introduction: Introduction to the problem (brief historical context), including the motivation and objectives of the Final Degree Project (TFG), as well as the structure of the report. This would be a first draft, it probably will be changed later on.
  • State of the art: scope of the problem, its history, definitions, and related properties (the scientific and technological substrate).
  • Technologies and tools to be used. Explanation of how PyG or other RL frameworks work (if we finally decide to use RL).
  • Planning and cost of the work.
