Critical Machine Based Scheduling -A Review

t. This article aims to identify the natural occurrence of the critical machines in
scheduling. The exciting scheduling in the real time manufacturing environment is focused on
considering equal weight-age of all the machines, but very few researchers were considered the
real time constraint(s) like processor/ machine/ workstation availability, etc.,. This article
explores the gap between the theory and practices by identifying the critical machine in
scheduling and helps the researcher to find the suitable problem in their case study
environment. Through the literature survey, it is evident that, in scheduling the occurrence of
the critical machine is in nature. The critical machine is found in various names and gives a
various range of weight-age based on the particular manufacturing environment and it plays a vital role in scheduling which includes one or more circumstances of occurrence in the production environment. Very few researchers were reported that in manufacturing environment, the critical machine occurrence is in nature, but most of the researchers were focused to optimize the manufacturing environment by only reducing the cycle time. In realtime manufacturing environment, the scheduling of critical machine(s) was keenly monitored and some weight-age was considered
