Dynamic weighted idle time heuristic for flowshop scheduling [PDF]

open access: yes, 2015
The constructive heuristic of Nawaz, Enscore and Ham (NEH) has been introduced in 1983 to solve flowshop scheduling. Many researchers have continued to improve the NEH by adding new steps and procedures to the existing algorithm.

Study of the dynamics of the movement mechanism of an overhead crane as a complex electromechanical system

open access: yesВісник Східноукраїнського національного університету імені Володимира Даля, 2022
The article studies the dynamics of the crane movement mechanism to take measures for their reliable operation and reduce the wear of movement mechanisms. For this, the following assumptions are accepted: transverse motion is not considered, the dynamics of engines and electric drive is not considered; the crane is presented in the form of a seven–mass

REDUCTION OF DYNAMIC LOADS DURING BRAKING OF THE OVERHEAD CRANE MOVEMENT MECHANISM

open access: yesBulletin of the National Technical University «KhPI». Series: Automobile and Tractor Construction
This study investigates the movement of a bridge crane during the braking of the travel mechanism. Complex dynamic phenomena accompany this process. The presented dynamic model of the crane allows for a deeper analysis of the influence of various factors on the operation of the travel mechanism, particularly the interaction of massive moving elements ...
