With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Mixed model two-sided assembly lines (MM2SAL) are applied to assemble large product models, which is produced in high-volume. So, the sequence planning of products to reduce cost and increase productivity in this kind of lines is imperative. The presented problem is tackled in two steps. In step 1, a framework is developed to select and prioritize customer orders under the finite capacity of th...

We discuss the development, integration, simulation, and flight test of a manned vehicle UAV mission system in a partially-known environment. The full control system allows a manned aircraft to issue mission level commands to an autonomous aircraft in realtime. This system includes a Natural Language (NL) Interface to allow the manned and unmanned vehicle to communicate in languages understood ...

Assembly lines are often indispensable in factories, and order to attain a certain level of assembly line productivity, multiple goals must be considered at the same time. However, these may conflict with each other, this is multi-objective balancing problem. This study considers four objectives, namely minimizing cycle time, number workstations, workload variance, workstation idle Since object...

A new hybrid assembly line design, called Parallel U-shaped Assembly Line system, is introduced and characterised along with numerical examples for the first time. Different from existing studies on U-shaped lines, we combine the advantages of two individual line configurations (namely parallel lines and U-shaped lines) and create an opportunity for assigning tasks to multi-line workstations lo...
