The permutation flowshop scheduling problem is a widely studied combinatorial optimization with several real-world applications. In this paper we address green variant of the controllable processing times and two objective functions: one related to service level factory (makespan) another total cost or energy/carbon consumption. For propose novel Critical-Path based Iterated Local Search. This ...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...
