Question 1

To minimize the size of queues in intermittent processes,schedulers need to address ______ major issues

Accepted Answer

Schedulers need to address three major issues to minimize the size of queues in intermittent processes: 1) the arrival rate of processes, 2) the service rate of processes, and 3) the variability of the arrival and service rates.

Question 2

Scheduling decisions have ______ time horizons.

Accepted Answer

C

Question 3

______ is concerned with regulating inputs to a work center in relation to output and available capacity so that the queues and waiting times of jobs can be managed and kept under control.

Accepted Answer

Input-output control is focused on managing and regulating the inputs to a work center based on its output and available capacity, aiming to control queues and waiting times for jobs.

Question 4

______ is the assignment of jobs to work or processing centers.

Accepted Answer

Loading is the process of assigning jobs to work or processing centers, focusing on the distribution of work among machines or workstations to optimize production efficiency.

Question 5

Which of the following is NOT an objective of scheduling?

Accepted Answer

Maximizing work-in-process inventories is not an objective of scheduling, as larger inventories often lead to longer lead times and increased carrying costs. The other objectives listed, such as effective resource usage, cost reduction, and productivity improvement, are common goals of scheduling.

Question 6

Detailed production schedule is the ______ set of decisions in the hierarchy of operations decision for ______ organizations.

Accepted Answer

The detailed production schedule is the last set of decisions in the hierarchy of operations decisions for manufacturing organizations, as it specifies the exact tasks to be performed at specific times by specific resources, following more strategic and tactical decisions.

Question 7

Products are made to order,and each order has its own unique material and processing requirements,processing sequence,and processing times in ______ processes.

Accepted Answer

Intermittent processes are designed to produce a variety of products with different processing requirements and are suited for customized or made-to-order production. Machine processes are more suited for mass production of standardized products, line processes are designed to produce a narrow range of products in high volumes, and continuous processes are used for the production of large volumes of standardized products with consistent materials and processing requirements.

Question 8

______ is the process of making specific resources such as labor,equipment,and facilities to produce a product or deliver a service available.

Accepted Answer

Scheduling is the process of arranging, controlling, and optimizing work and workloads in a production process or manufacturing process. It helps in making specific resources like labor, equipment, and facilities available at the right time for the production or delivery of services.

Question 9

______ type(s)of Gantt charts is/are used for scheduling decisions.

Accepted Answer

Two types of Gantt charts are commonly used for scheduling decisions: the "task-oriented" Gantt chart and the "resource-oriented" Gantt chart. Task-oriented Gantt charts focus on the sequence and duration of tasks, while resource-oriented Gantt charts emphasize the allocation and usage of resources over time.

Question 10

Which of the following is NOT one of the major issues to be addressed by schedulers in order to reduce the size of the queues in intermittent processes?

Accepted Answer

Worker assignment is not directly related to reducing the size of queues in intermittent processes. The major issues to be addressed by schedulers include input-output control, loading, and sequencing, which are all directly related to managing the flow and processing of work items to reduce queue sizes. Worker assignment, while important for overall efficiency and productivity, does not directly impact the size of queues in the same way these other factors do.

Question 11

______ calculations are used to determine a schedule that allocates the capacity of the line among the several products.

Accepted Answer

Runout time calculations are used to determine a schedule that allocates the capacity of the line among the several products by estimating when the inventory of each product will run out.

Question 12

The use of dams in rivers to control water flow is a simple example of ______.

Accepted Answer

Input-output control is the process of controlling the flow of water into and out of a system. Dams are used to control the flow of water in rivers, so they are an example of input-output control.

Question 13

Monthly or weekly service schedule is the ______ set of decisions in the hierarchy of operations decision for ______ organizations.

Accepted Answer

In service organizations, the monthly or weekly service schedule is the last set of decisions in the hierarchy of operations decisions, as it involves detailed planning and scheduling of resources to meet customer demand.

Question 14

Scheduling for line processes is often referred to as ______.

Accepted Answer

Line processes involve a sequence of operations and the scheduling of these operations is typically referred to as flow-shop scheduling. Cluster scheduling refers to scheduling tasks on a cluster computing environment, batch scheduling involves scheduling a group of jobs to be processed together, and job-shop scheduling involves scheduling a variety of jobs with different requirements on the same production line.

Question 15

______ is a form of line process scheduling in which many of the scheduling decisions are predetermined when the production systems are designed.

Accepted Answer

Flow-shop scheduling is a form of line process scheduling in which the sequence of operations and the machines on which they are to be performed are predetermined. This scheduling method is commonly used in industries where the production process follows a fixed sequence, such as assembly lines in manufacturing plants.

Question 16

Scheduling decisions are typically ______ in scope.

Accepted Answer

Scheduling decisions are specific to a particular task or operation, which means they are typically narrow in scope.

Question 17

______ are high-volume product processes that typically produce standardized products and require identical or similar operations.

Accepted Answer

Line processes are high-volume product processes that produce standardized products and require identical or similar operations. Intermittent processes are flexible processes that produce customized products in low volumes. Machine processes refer to the use of machinery to perform specific tasks, and outlier processes are processes that fall outside the norm and are not typically used in production.

Question 18

Which of the following statements is true about process scheduling?

Accepted Answer

Job-shop scheduling is generally considered to be more complex than line process scheduling due to the varied tasks and operations involved in a job-shop environment. Line process scheduling involves a more standardized production process and is generally easier to schedule.

Question 19

In the hierarchy of decisions made in the field of operations,detailed scheduling is the ______ step before the actual manufacture of the product or delivery of service.

Accepted Answer

Detailed scheduling is the final step in the hierarchy of decisions made in operations before the actual manufacture of the product or delivery of service begins. It involves allocating specific resources to specific tasks according to a detailed plan.

Question 20

Which of the following is NOT one of the objectives of loading decisions?

Accepted Answer

The objective of loading decisions is to allocate work to work centers or machines in the most efficient way possible. This includes minimizing idle time, minimizing setup time and costs, and maximizing processing time. However, maximizing processing time is not one of the objectives of loading decisions, as this could lead to overloading a machine or work center, which would ultimately decrease efficiency.
