Optimizing Work Scheduling In Shop Floor Using Ant-Colony Algorithm
Abstract: A job shop manufacturing system is specifically designed to simultaneously produce different types of products in a shop floor. Job shop scheduling problems (JSSPs) have been studied extensively and most instances of JSSP are NP-hard, which implies that there is no polynomial time algorithm to solve them. As a result, many approximation methods have been explored to find near-optimal solutions within reasonable computational efforts. Furthermore, in a real world, JSSP …
