In this paper, we present a theoretical investigation and an extensive computational study of exterior point simplex algorithm (EPSA) initialization methods for the assignment problem (AP). We describe the exterior point algorithm using three different initialization methods. Effective implementations are explored for each initialization method. Then we perform an experimental evaluation on a large set of benchmark problems from the TSPLib 95 and OR Library collections. The results obtained demonstrate the advantages of the three initialization methods. Finally, we give a theoretical justification of the initialization methods efficiency. We explain theoretically the computational ranking for these methods.

متن کاملModified Convex Data Clustering Algorithm Based on Alternating Direction Method of Multipliers
Knowing the fact that the main weakness of the most standard methods including k-means and hierarchical data clustering is their sensitivity to initialization and trapping to local minima, this paper proposes a modification of convex data clustering in which there is no need to be peculiar about how to select initial values. Due to properly converting the task of optimization to an equivalent...

In this paper, an analytical approach is used for assembly line rebalancing and worker assignment for single and mixed-model assembly lines based on a heuristic-simulation algorithm. This approach helps to managers to select a better marketing strategy when different combinations of demands are suitable.Furthermore, they can use it as a guideline to know which worker assignment is better for ea...
متن کاملHybrid Meta-heuristic Algorithm for Task Assignment Problem
Task assignment problem (TAP) involves assigning a number of tasks to a number of processors in distributed computing systems and its objective is to minimize the sum of the total execution and communication costs, subject to all of the resource constraints. TAP is a combinatorial optimization problem and NP-complete. This paper proposes a hybrid meta-heuristic algorithm for solving TAP in a ...
متن کاملAn algorithm for integrated worker assignment, mixed-model two-sided assembly line balancing and bottleneck analysis
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...
