Which scheduling technique should be employed

So, using a backward scheduling method you can know: The start date depending on the availability of resources. The key variables that need to be known are start date and due date or shipping date for forward and backward scheduling respectively.

Other variables that affect both the scheduling processes include the type of jobs, the nature and availability of resources, processing time, changeover time, process routings, parallel and dependent tasks, number of work shifts and planned maintenances. Scheduling of tasks is multi-faceted—taking into account various production variables and estimation occurs across each stage the project lifecycle.

In practice, just-in-time schedule in modern production processes is accomplished with a mix of forward and backward scheduling methods. Some orders need to be filled as soon as a slot is available while other orders are planned for just-in-time delivery. MRP systems by leading vendors allow for both forward and backward scheduling features.

These methods should complement each other for any production and manufacturing system to be efficient. About Terms Privacy Support. What is Forward and Backward Scheduling? Sujata Upadhyay. FCFS: first come, first served b. SPT: shortest processing time c. EDD: earliest due date d. LPT: longest processing time Average completion time for a schedule sequence at a work center is total a.

CR: critical ratio The priority rule which processes jobs according to the smallest ratio of due date to processing time is : a. FCFS seems fair to customers b. FCFS minimizes the average number of jobs in the system c.

FCFS minimizes the average lateness of all jobs d. FCFS maximizes the number of jobs completed on time The most appropriate sequencing rule to use if the goal is to dynamically track the progress of jobs and establ is h relative priority on a common bas is is a.

Johnson's rule Use of the sequencing rule Shortest Processing Time generally results in a. Johnson's Rule b. A recent advance in short-term scheduling that makes use of expert systems and simulation in solving dynamic scheduling problems is a.

The operations manager would like to significantly reduce the batch size. What would you suggest? What should be the setup cost? If the ir first target were to cut the current lot size in half, by what proportion must setup cost change? Setup cost must be cut to one-fourth its current value. Setup cost must also be cut in half from its current value. Setup cost must double from its current value.

Cannot be determined. The emphas is is on staffing levels, not materials. Labor use can be intensive, and labor demand is usually stable.

While it seems to be a great technique for tracking a project, it does have certain limitations you cannot assign tasks to certain people and you cannot see task dependencies.

Resource scheduling tools can help a project manager in the allocation of resources and finish up a project within the prescribed time span. They also help in preparing schedules for all the projects that are to be taken up in the future.

Studying the past performance of your team, the hindrances faced while pursuing a project and how were those obstacles overcome come very handy. Scheduling must be an integral part of project management. It just does not help save time but gets the project to be organized. This is a guide to Project Scheduling Techniques. Here we discuss the various Techniques and an outline of Project Scheduling.

Lastly, add milestones and deliverables to your project. A critical path helps to visualize the project flow and calculate its duration when all dependencies and deliverables are known.

This technique may not be so handy if there are many uncertainties in the project. This technique also illustrates dependencies between tasks. Using a network framework similar to CPM, consisting of these tasks, you can estimate different timelines for a project depending on the level of confidence:. A disadvantage of this approach is also a need to know the tasks and dependencies between them in order to fully benefit from this technique.

Duration compression is a way to shorten a schedule. It may be of use if the project is going late and you have to find a way to adjust a schedule without changing the scope of the project. There are two techniques that you may apply: fast tracking and crashing.

For that, take a look at the critical path to decide which activities could be fast-tracked. At this point you could start with the design phase, and only start with software development if design is ready. But if you need to fast track both processes, you can start software development after first, the most important designs are ready. Although fast tracking may seem appealing, remember about the risks, too.

Another compression technique is crashing, which is about adding extra resources to finish the project on time.
