The importance of this era's architecture is because large changes in conceptual and physical context occurred slowly in Iranian architecture during this time. These changes, especially from the Nasserian period (the second Qajar era), h...

This research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. This objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. Moreover, this type of problem is NP-hard and solving this probl...
