Group Technology (GT) is the exploitation of the similarities among processes and component designs in such a way that it increases the utilization of resources, and eliminates/reduces non value added activities, i.e., material handling, scraps, downtime, etc [3].
The considered cell scheduling problem can further be extended to include issues relating to material handling time, buffer size constraints, etc.

Indeed, nowadays the environmental impact issue of the manufacturing sector is extremely topical, particularly given that the energy consumptions of industry, including the materials production, represents the 35% of total amount, and the sector CO2 emissions, derived both from direct and indirect emissions, represent more than thirty percent of global emissions [5].
It is also possible to evaluate the advantages of scheduling in terms of energy savings, using a Key Performance Indicator (KIP).

It has no internal movement artifacts but simple structure, excellent heat and mass transfer characteristics, low operating costs, and it is easy to control the temperature of the material and handle solid particles.
It is a key parameter in reactor project designing.
Mass transfer coefficient Mass transfer is the key phenomenon in the chemical reactions taking place in the slurry bubble column reactor.
So the mass transfer in gas-liquid phase is explored frequently in practical problems, and the mass transfer coefficient can be described with volumetric mass transfer coefficient, i.e. kLa, it is a key parameter in the use of designing and scale-up.
