In this paper, a quaternion firefly algorithm is utilized to solve a multi-row facility layout design problem with the objective of minimizing the total cost of transportation. A quaternion firefly algorithm takes the motion of the firefly as a quaternion one. Consequently, the solution space is explored more accurately and the answers are of higher quality. That is, the answers are considerabl...

This paper presents a facility for definition and management of federated clusters of interrelated information. In a co-working environment, team members need to exchange information in order to coordinate their tasks execution, where typically the information is distributed over several cooperating autonomous systems. The co-working facility described in this paper supports the sharing and exc...

facility layout problems (FLPs) are common problem in several manufacturing industries because FLPs have a great impact on production operations. Efficient manufacturing facility layout design could lead to lower manufacturing costs. Therefore, many sub problems should be addressed and considered from design stage. This research proposes a new framework for mix-model assembly line (MAL) manufac...

Increasing global competition has enforced all members of supply chains to optimize their activities to achieve high performance and customer satisfaction. A company can improve its supply chain performance in terms of responsiveness and efficiency by means of good facility layout design. Facilities are the places in the supply chain network where product is stored, manufactured, assembled or f...

The dynamic facility layout problem (DFLP) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. In this paper a new optimization algorithm inspired from colonizing weeds, Invasi...

Genetic algorithms have proven to be a wellsuited technique for solving selected combinatorial optimization problems. When solving real-world problems, often the main task is to find a proper representation for the candidate solutions. Strings of elementary data types with standard genetic operators may tend to create infeasible individuals during the search because of the discrete and often co...

The single-row facility layout problem (SRFLP) is an NP-hard combinatorial optimization problem that is concerned with the arrangement of n departments of given lengths on a line so as to minimize the weighted sum of the distances between department pairs. (SRFLP) is the one-dimensional version of the facility layout problem that seeks to arrange rectangular facilities so as to minimize the ove...
