Abstract

fetched live from OpenAlex

This paper presents a methodology which uses Genetic Algorithms (GA) for task scheduling and management in an environment where multiple jobs compete for a limited number of resources. The primary objective of the developed system of task scheduling and management is to minimise the cost of resources using available resources while ensuring that the jobs are completed within stipulated timeframes while meeting the task specifications and performance criteria. Once the resources are allocated by the GA-based scheduling algorithm to complete a given set of jobs, it is necessary to continuously monitor the progress of jobs and changes in the environment and in the event of such situations as performance degradation and machine breakdowns, to plan, allocate and rearrange the resources to achieve the system objective. In this paper, a technique is developed to accommodate machine breakdowns and unavailability of machines due to prior assignment or maintenance. Another feature of the developed algorithm is the use of domain knowledge about the process to expedite the evolution process. In the present paper, methodology is also developed to accommodate high priority jobs that may be introduced after the initial scheduling. The developed methodology is applied to plan the activation and post activation processes in an activated carbon manufacturing plant and to schedule and manage the resources such as kilns, crushers, blenders, washers and dryers in the plant. The results demonstrate the effectiveness of the developed approach.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
