Motivated by an application in rail car maintenance, we study a variant of makespan-minimizing flexible job shop scheduling with work centers (FJc). In standard FJc a work center contains parallel machines, i.e. any machine in the work center is accessible whenever idle. In our variant, a ...
Device to remove blockages in drains consists of flexible tube and water tank with electrical heater to produce hot high pressure steamThe device has a housing (1) and a longitudinally rigid elastic tube (2) with thermally insulating lining (9) and mouth piece (3). The blockage in a drain...
With multiple timing constraints applied, our CTS method first introduces node clustering and buffering to construct an initial clock tree in a bottom-up fashion, pursuing the minimum clock skew with macro blockages eluded. Then tree node pulling up and buffer insertion may be used to further ...

The flexible job shop scheduling problem is a typical and complex combinatorial optimization problem. In recent years, the assembly problem in job shop scheduling problems has been widely studied. However, most of the studies ignore the learning effect of workers, which may lead to higher costs th...
The article presents the problems connected with the performance evaluation of a flexible production system in the context of designing and integrating production and logistics subsystems. The goal of the performed analysis was to determine the parameters that have the most significant influence on the...
