A methodology for solving single-model stochastic assembly line balancing problem

If the improvement in the solution stabilizes beyond a r value, it implies that the value of r is either larger than E of the scheduling procedure or very close to it. The stochastic model is based on the assumption that the task times will follow a predetermined probabilistic distribution function. We introduce an algorithm framework that uses multiple search operators in each generation. Some of the known issues such as learning curves can be addressed by means of incorporating the function for their learning curve[13].
