How To Draw The Following Scheduling In A Gantt Diagram For Fifo

Yes, It is correct.

In FIFO algorithm (also known as FCFS (first come first serve)), CPU executes the process which came earliest until it is complete. So,Process P1 starts execution at time 0 and it takes 4 CPU (0-1, 1-2, 2-3, 3-4) burst to be executed. and while this process is in execution all other process will have to wait.As soon as P1 finishes execution, CPU starts executing P2. So, P2 starts execution at time 4 and it takes 1 CPU (4-5) burst to be executed.Similarly, other processes are executedNow coming to wait time:P1 arrived at time 0 and CPU started its execution at time 0 , so wait-time for P1 = 0 - 0 = 0P2 arrived at time 1 and CPU started its execution at time 4 , sowait-time for P2 = 4 - 1 = 3P3 arrived at time 2 and CPU started its execution at time 5 , sowait-time for P3 = 5 - 2 = 3........ SO ONsee the image

Yes, it’s correct.Shortest-Job-First (SJF) scheduling can be preemptive or non-preemtive. SJF is preemptive in this case, but can also be non-preemptive. In this preemptive scenario, the algorithm choses the process with the least burst time in the order they arrive. If a process that has less burst time than the process that is running, the arriving process will take the CPU because its burst time is smaller; it is the preemptive scheduling in a nutshell.

I’m not sure what “small scale” means to you.Many bigger companies find great success in deploying Lean Thinking, or said another way, the Toyota Production System. I can attest that I’ve used this for over 30 years and is has NEVER let me down. I’ve used the practices in turnaround situations, growth situations, supply chain practices, and even office and other business processes.To make this work, the leader (NOT the second in command) has to be the chief champion as many of the changes will seem counter-intuitive to parts of the organization. The BOSS has to make things stick.The second necessary ingredient is to have someone who knows what they are doing regarding deployment of the various elements of lean; a guru. The boss does not have to play this role-they just have to provide air cover for the guru.If your organization is too small for this (you said small scale), then here are a few suggestions.Look in your factory for processes which require “setup”. Then work on reducing or eliminating set ups. This is a foundation for subsequent improvements. You will have slow throughput, scrap, and working capital wasted if you have big batch processes. I’ve personally worked in factories where my team eliminated ALL setups.Understand the principles of 5S. Google this if you want a detailed explanation. Then do Gemba Walks in your factory; you look for anomalies in your processes and practices and start to ask questions. As part of this learn the concept of “Five Why’s” which is the way you get to root-cause issues. Fix the root causes, not the symptoms.Hire people who are willing and can do multiple jobs. You want an organization which can handle change, not an army of specialists. If you reach 50 employees, hire the guru. Trust me, this will not cost you anything.Ensure the organization devotes a part of its time to improvement. Otherwise you are just talking the talk.These are just a few starting suggestions. When you are small scale, it can be very difficult for leadership of the organization to find the mental bandwidth to create a persistent and effective program. Be aware and be disciplined.
