Scheduling is an important tool for manufacturing and engineering, where it can have a major impact on the productivity of a process. In this paper, we use flow shop scheduling in KCCL (Kohinoor Chemical Company Limited) & find out the optimum policy in scheduling operating several machines to produce soap & to reduce idle time of machines. Considering different type of machine that also absorbs different production time. The industry tries to identify their idle time & best presidential relationship between the machines. We use Johnson’s scheduling algorithm & a numerical output is achieved.
