Q

MRP has 2 major functions:

A

1-Based on the MPS quantities and due dates for end items, create a time phased plan that determines what components are needed to make a product and when. This is called a priority plan.

2-Maintain and adjust the priority plan to account for changes in customer orders,forecasts,material shortages and production problems.

A

an inversion of a BOM information.

29
Q

A where-used report lists …

A

all of the items, or parents, in which a component is used whether or not there is a demand for the parent.

30
Q

In a where-used report the data may be …

A

Single level or full level.

31
Q

Where-used informatio has the following uses:

A

1-identifying the parent items affected by an engineering change and assessing the impact of the change

2-assessing the aggregate impact of costing changes for a component

3-assessing the effects of component scarcity

4-assessing the benefits and costs of standardizing similar components, preventing stockkeeping unit proliferation

32
Q

A pegging report is …

A

similar to a where-used report except that it shows only those parents for which there is an existing requirement.

33
Q

The pegging report shows the following:

A

1-the parents creating demand for components

2-the quantities required

3-when those quantities are required

4-where-used logic to identify current sources of demand

5-may be single-level or multi-level

34
Q

The uses of BOM are :

A 
1-Product definition
2-Engineering change control
3-Planning
4-Customer service

37
Q

MRP creates the priority plan through:

A

1-Exploding and offsetting requirements

2-Calculating gross and net requirements

38
Q

Exploding and offsetting requirements and calculating gross and net requirements will bring us to the point in the planning process where a developed priority shows …

A

the time-phased dates and quantities for planned order releases and receipts for both purchased components and manufactured components.

39
Q

The MRP process uses key inputs to determine …

A

an end item’s required components(what), the quantities of those components(how much) and a time-phased plan(when) for the operations that will convert the end item into a finished product.

40
Q

The time-phased plan or priority plan expresses the necessary actions in the form of …

A

planned order releases and receipts.

41
Q

To create a priority plan MRP uses a process called …

A

lead-time offsetting and exploding.

42
Q

Manufacturing lead-time data are found in the …

A

item master record.

43
Q

Offsetting is the processof determining …

A

when a planned order release is needed in advance of the planned order receipt date of the item.

44
Q

Exploding is the process of …

A

determining the total of each component needed for a parent based on the BOM.

45
Q

Net requirements =

A

46
Q

The planning horizon should be as long as the …

A

cumulative lead-time.

47
Q

The quantity shown in the projected available row is the projected available balance at the …

A

end of the period, all other quantities are for the beginning of the period.

48
Q

MRP softwares perform,two major functions :

A

1-Perform gross to net, lead-time offset, and explosion calculations.

2-Create action and exceptions messages.

49
Q

On the basis of action and exception messages, the planner will …

A

release planned orders, expedite or de-expedite component schedules, or change order quantities.

50
Q

In managing the priority plan, the material planner works with three main types of orders:

A

1-planned orders

2-firm planned orders

3-released orders

51
Q

Planned orders are …

A

created by planning software when it encounters net requirements. The net requirement generates planned order receipts in the system.

52
Q

A firm planned order is …

A

a tool that enables the planner to overridenthe MRP logic.

53
Q

Planners are responsible for releasing planned orders, aided by action messages from the MRP system. Once released, a planned order becomes …

A

an open order to the factory or to the supplier. It appears as a scheduled receipt.

54
Q

A released order is under the control of the planner and is subject to …

A

expediting, de-expediting,change order quantities and even cancellation.

55
Q

The release of the order involves :

A

1-Releasing a planned order

2-Scheduling a receipt

3-Creating an open order

4-Allocating components to the order

56
Q

An open order is …

A

an authorization to purchasing to buy the necessary materials or to manufacturing to make the components.

57
Q

The planner has the general responsability of managing the current priority plan such as …

A

planned orders,open orders,and end-item due dates.

58
Q

External events that might affect order priorities are:

A

1-Changes to customer orders
2-Supplier shortages
3-Late deliveries and lower than required quantities from suppliers

59
Q

Internal events that might affect order priorities are:

A

1-Lower yields or higher scrap factors than planned

2-Late or early open order completions

3-Capacity or resource constraints

4-Material shortages caused by inventory record inaccuracies that hide shortages or surpluses of components or end items and lead to the need to expedite or de-expedite.

60
Q

There basically are two sets of actions available to the planner:

A

1-Maintain the priority plan by taking actions to maintain the scheduled due dates for the production of components or the end item.These would include expediting or de-expediting

2-Replan the due date if an event does not enable the maintaining of a due date.
