Salient points of scheduling operations for low v/s high volume operations are to be highlighted. Concept Introduction: Conceptually, there are no differences in scheduling for high v/s low volumes. All schedules result in Queues, waiting times, idle times, etc. The type of schedule depends on the manufacturing line design; the number of resources to be shared /bottlenecks, the criticality of delivery commitments, space/handling requirements, etc.

Expert Solution & Answer

Explanation of Solution

Lowest volume (one) operation is a project and the scheduling is totally different from those used in manufacturing. This is through Gantt charts, networks etc.
High volume operations may be associated with longer production runs on flow lines. Scheduling may require smaller batch sizes to be used with more setups. This will require working on SMED (single minute exchange of dies).
Low volume operations can be exemplified by job shops where many resources are likely to be shared even if all of these may not be bottlenecks. This is likely to require the use of mathematical models/algorithms.
In very operations, simple priority rule may also work e.g. first come first served, earliest delivery commitment etc.

what is the arithmetic average annual return per year?

Describe a simple sales information system for an online store, including its products, branches, and its appraisal, so that it captures the attention of an average person without a university degree or a particular career, and develop a report about it.

Note: A waiting line model solver computer package is needed to answer these questions. The Kolkmeyer Manufacturing Company uses a group of six identical machines, each of which operates an average of 23 hours between breakdowns. With randomly occurring breakdowns, the Poisson probability distribution is used to describe the machine breakdown arrival process. One person from the maintenance department provides the single-server repair service for the six machines. Management is now considering adding two machines to its manufacturing operation. This addition will bring the number of machines to eight. The president of Kolkmeyer asked for a study of the need to add a second employee to the repair operation. The service rate for each individual assigned to the repair operation is 0.40 machines per hour. (a) Compute the operating characteristics if the company retains the single-employee repair operation.
