A traditional assembly system-fixed worker line (FW) designed by assigning one operator to each workstation performing an assembly task at that workstation on the line, has some deficiencies, such as low flexibility, constant demand and difficult balancing. A walking-worker line (WW), with an assembly worker travelling with the work along the line, has several advantages over a traditional line...

The availability of automated production lines and data has opened a new opportunity for improving the geometrical quality assemblies by using digital twin in concept smart assembly line. In this concept, is generated from scanned incoming parts each assembly. process then simulated variation simulation tools. Subsequently, optimal parameters are found utilizing optimization algorithms along wi...

Assembly line balancing problems consist in partitioning the work necessary to assemble a number of products among di erent stations of an assembly line. We present a hybrid approach for solving such problems, which combines constraint programming and integer programming.

This paper addresses a multi-objective mixed-model two-sided assembly line balancing and worker assignment with bottleneck analysis when the task times are dependent on the worker’s skill. This problem is known as NP-hard class, thus, a hybrid cyclic-hierarchical algorithm is presented for solving it. The algorithm is based on Particle Swarm Optimization (PSO) and Theory of Constraints (TOC) an...
