Web Viewer for Validation and Analysis of Solutions to the Sequence-Dependent Deterioration Scheduling Problem

This paper presents a web-based viewer for validating, analyzing, and visualizing solutions for the Sequence-Dependent Machine Deterioration Job Scheduling Problem on unrelated parallel machines. The problem is that each processed job reduces machine performance, affecting the actual processing times of subsequent jobs. The tool allows users to input benchmark instances in the format commonly adopted in the literature and provide one or more candidate solutions represented by the job sequences assigned to each machine. Based on these data, the system checks basic inconsistencies and computes progressive machine performance, starting and completion times, delays, makespan, and Total Delay Time. It also generates a detailed calculation table, a Gantt chart, a scatter plot for multiple solutions, and an approximate identification of the Pareto frontier. The viewer contributes to transparency, reproducibility, and solution understanding, supporting research, teaching activities, and the generation of scientific documentation.
