High-Performance Discrete Particle Swarm Optimization (PSO) Algorithm and Software Development of Application on JSSP
Abstract
- Conducted research to study industrial Job-shop Scheduling Problem(JSSP), and designed a coding and decoding scheme.
- Prototyped and implemented the Cooperative PSO algorithm for optimizing JSSP problem in MATLAB.
- Discovered optimal combination of parameters for CPSO algorithm using Response Surface Methodology(RSM).
- Designed 8 JSSP testing cases for CPSO algorithm with optimal parameters, and mapped correlated algorithm convergence curve and scheduling Gantt Graphs.
- Conducted performance analysis from two aspects.
- Algorithm Improvement: CPSO algorithm reduced at most 17.68% error to theoretical optimal solution compared to that of standard PSO algorithm;
- Parameter Optimization: approximately 87.5% of 8 test cases results made better performances with aforementioned optimal parameters than original parameters did.
- Developed a user-friendly desktop client: PSO-related JSSP software system in C# and SQL Server, providing the capability for users to obtain fast results by inputting key parameters.
