(590a) ISA-95 Based Scheduler Using Flexible Heuristics


The main challenge in productizing scheduling solutions is often twofold: 1) Defining a landscape that can host the algorithmic environment, collect information necessary to formulate a realistic problem instances and communicate the results into production, 2) Providing an algorithm that works efficiently for various cases and provides - if not optimal - solutions that can be used in practice.
In this presentation we will address both challenges and present a scheduling solution that uses ISA-95 standard for importing the information based on which the problem is modeled. To ensure an efficient operation the solution uses a number of heuristic algorithms, which in many cases perform close-to-optimally. Different use cases are shown, along the discussion on how the algorithms performance can be affected both in terms of efficiency and quality.
