Question 1

A BOM file is often called a product structure file or product tree because it enumerates all of the component parts of the end item product.

Accepted Answer

A BOM file is commonly referred to as a product structure file or product tree because it lists all of the various component parts that are included in the final product.

Question 2

One of the biggest complaints by users of MRP systems is that MRP is too flexible in making changes in schedules when the need arises.

Accepted Answer

One of the biggest complaints by users of MRP systems is that MRP is inflexible in making changes in schedules when the need arises, as the system is based on a predetermined set of inputs and calculations.

Question 3

In today's modern world of rapid computing and just-in-time replenishment of supplies,freezing the master production schedule is unnecessary.

Accepted Answer

Freezing the master production schedule is still necessary to provide stability and predictability in production planning, even with advanced computing and supply chain methods.

Question 4

A modular bill of materials includes items with fractional options.

Accepted Answer

A modular bill-of-materials typically includes predefined modules or components that can be combined in various configurations to create a final product, rather than items with fractional options.

Question 5

To implement a MRP system successfully,a high degree of inventory and bill-of-material accuracy is required.This may involve significant change in how a firm operates.

Accepted Answer

MRP (Material Requirements Planning) is a computerized system for inventory and production planning. For MRP to work efficiently, inventory and bill-of-material accuracy is essential. This may require significant changes in the way a company operates, including improving inventory accuracy through inventory control systems, cycle counting, and improving accuracy in bills of material by reviewing and updating them regularly. Hence, the statement is true, and option A is correct.

Question 6

Computing the quantity of each component that goes into a finished product requires expanding (or exploding)each item in a product structure file and summing at all Levels.

Accepted Answer

This is true. To calculate the quantity of each component needed for a finished product, you must expand each item in a product structure file and sum them up at all levels.

Question 7

In a net change MRP system requirements and schedules are considered rigid and never updated.

Accepted Answer

In a net change MRP system, requirements and schedules are updated as changes occur in the demand or inventory levels.

Question 8

In a net change MRP system requirements and schedules are updated whenever a transaction is processed that has an impact on the item.

Accepted Answer

In a net change MRP system, requirements and schedules are updated dynamically whenever a transaction is processed that affects the item, resulting in a more accurate and timely view of inventory and production needs.

Question 9

Low Level coding in MRP indicates the exact status of each item managed by the system in "real time".

Accepted Answer

Low Level coding in MRP (Material Requirements Planning) is used to determine the lowest level in the bill of materials where a part resides, not to indicate real-time status.

Question 10

Net change MRP systems are "activity" driven.

Accepted Answer

Net change MRP systems focus on tracking changes in activity levels, such as sales orders or production rates, in order to dynamically adjust production and inventory levels. This is in contrast to traditional MRP systems which operate on fixed schedules and require manual adjustments.

Question 11

An MRP program with a capacity requirements planning module allows rescheduling to try to Level capacity.

Accepted Answer

An MRP program with a capacity requirements planning module can reschedule to try to level capacity, ensuring that there is enough capacity to meet the production requirements. This is done by analyzing the production schedule and identifying any periods where capacity is overloaded or idle, and then rescheduling to balance the workload.

Question 12

One of the outputs of an MRP system is a bill of materials (BOM)file.

Accepted Answer

A bill of materials (BOM) is an input to an MRP system, not an output. It is used to determine the materials and components needed for production.

Question 13

A modular bill of materials is the term for an item that can be produced and stocked as a subassembly.

Accepted Answer

A modular bill of materials is designed to be produced and stocked as a complete subassembly. This can improve efficiency and reduce assembly time for the final product.

Question 14

The MRP program performs its analysis from the bottom of the product structure trees up,imploding requirements Level by Level.

Accepted Answer

The MRP (Material Requirements Planning) program performs its analysis from the top of the product structure tree down, exploding requirements level by level.

Question 15

Computing the quantities of each component that goes into a finished product requires expanding (or exploding)each item in a product structure file and summing at all Levels.

Accepted Answer

This is true. To calculate the quantities of each component, we need to break down the entire product structure file by expanding each item and adding up the components at all levels.

Question 16

If you cannot provide a master production schedule (MPS)as an input file,you cannot run a material requirements planning (MRP)system.

Accepted Answer

The MPS is a key input to MRP as it outlines the production plan for a time horizon and serves as the basis for determining the material requirements needed to support production. Without an MPS, MRP cannot generate accurate material requirements and schedules.

Question 17

The philosophy of material requirements planning is that materials should be expedited when their lack would delay the overall production schedule and de-expedited when the schedule falls behind and postpones their need.

Accepted Answer

Material requirements planning is a system that helps to ensure that the necessary materials are available at the right time during the production process. The philosophy of material requirements planning is to expedite the materials when their lack would delay the production schedule and de-expedite them when the schedule falls behind and postpones their need. This approach helps to keep the production process on track and ensures that the necessary materials are available when needed.

Question 18

The "theme" of MRP is getting the right materials to the right place before they are needed.

Accepted Answer

The answer of The "theme" of MRP is getting the...

Question 19

Net change MRP reflects the exact status of each item managed by the system in "real time".
Goal: 3

Accepted Answer

The net change MRP system immediately updates the status of each item as changes occur, so it reflects the true, real-time status of each managed item.

Question 20

In a net change MRP program,a change in one item will result in a completely new inventory plan and schedule for every item in the master production schedule.

Accepted Answer

In a net change MRP program, changes are made only for those items directly affected by the change, not for every item in the master production schedule.
