Latest Patents

Shailendra E Jain holds a patent for "Set-up optimization for flexible manufacturing systems." This invention presents an iterative method of sequencing jobs in a flexible manufacturing environment, where jobs have sequence-dependent set-up times. The method approximates optimal sequencing while requiring only modest computational resources. The invention recasts the sequence of manufacturing jobs as a dynamic traveling salesman problem (TSP). It allows the system to reconfigure itself and execute each job similarly to how a salesman visits a sequence of cities, with distances between cities changing based on previously visited cities. The first step reduces the dynamic TSP to a static TSP, fixing distances between job pairs as a monotonic function of shared parts. The second step maximizes total distance by exploiting part commonality, providing a good initial solution. The invention iteratively improves this solution by perturbing the initial sequence and calculating changes in part swaps required for reconfiguration. The process continues until no further improvements are found. A modified algorithm optimizes the number of configuration changes for the final sequence, ensuring near-optimality through a lower bound calculation.
