We provide a complete analysis of the complexity of flow-shops, open-shops and job-shop problems. We introduce a polynomial-time algorithm for the two-machine flow-shop, and prove NP-hardness when an arbitrary
that each job has a certain condition that you can start a job only if the start time of the current job is greater than the finish time of the previous job. You are required to develop some algorithm such that the job start time and the finish time does not coincide with other jobs....
The job scheduling problem in a partitionable mesh-connected system in which jobs require square meshes and the system is a square mesh whose size is a power of two is discussed. A heuristic algorithm of time complexity O(n(log n+log p)), in which n is the number of jobs to be sche...
Malleable job scheduling problem with constant overhead (c) on m machines F “Final” state that algorithm OCS is trying to reach I Same as I(n+1), the completion-time difference between the most loaded machine and the least loaded machine at the end of the online algorithm’s schedul...
However, due to the complexity of the algorithms, task assignment takes a lengthy time. Social Spider Optimization (SSO) technique is a recently introduced swarm intelligence algorithm that mimics the social conduct of a spider. The technique deliberates the working principle of spiders concerning the...
The flexible job shop scheduling problem with parallel batch processing operation (FJSP_PBPO) in this study is motivated by real-world scenarios observed in electronic product testing workshops. This research aims to tackle the deficiency of effective me

the author presents an algorithm based on ACO paradigm to solve thejointproduction and maintenance scheduling problem. This approach is focused to deal with the parallel machine case, to improve the quality of solutions; an algorithm based on Multi-Objective Ant Colony Optimization (MOACO) approach...
