Which is a listing of all the subassemblies parts and raw materials that go into a parent assembly showing the quantity of each that is required to make an assembly?

Q: What is netting in manufacturing?

Netting. The next step is netting, in which any stock on hand is subtracted from the gross requirement determined through explosion, giving the quantity of each item needed to manufacture the required finished products.

1) A listing of all the subassemblies, intermediates, parts, and raw materials that go into a parent assembly, showing the quantity of each required to make an assembly. It is used in conjunction with the master production schedule to determine the items for which purchase requisitions and production orders must be released. A variety of display formats exists for bills of material, including the single-level, indented, modular (planning), transient, matrix, and costed. 2) A list of all the materials needed by a contract manufacturer to make one production run of a product's piece parts/components for its customers. It may also be called the formula, recipe, or ingredients list in certain process industries.

bill-of-material explosion

The process of determining component identities, quantities per assembly, and other parent-component relationship data for a parent item. Explosion may be single level, indented, or summarized.

To perform a bill-of-material explosion.

A planned order that can be frozen in quantity and time. The computer is not allowed to change it automatically; this is the responsibility of the planner in charge of the item that is being planned. This technique can aid planners working with MRP systems to respond to material and capacity problems by firming up selected planned orders. In addition, firm planned orders are the normal method of stating the master production schedule.

The total of independent and dependent demand for a component before the netting of on-hand inventory and scheduled receipts.

indented bill of material

A form of multilevel bill of material. It exhibits the highest-level parents closest to the left margin, and all the components going into these parents are shown indented toward the right. All subsequent levels of components are indented farther to the right. If a component is used in more than one parent within a given product structure, it will appear more than once, under every subassembly in which it is used.

A technique used in MRP where a planned order receipt in one time period requires the release of that order in an earlier time period based on the lead time for the item.

material requirements planning (MRP)

A set of techniques that uses bill of material data, inventory data, and the master production schedule to calculate requirements for materials. It makes recommendations to release replenishment orders for material. Further, because it is time-phased, it makes recommendations to reschedule open orders when due dates and need dates are not in phase. Time-phased MRP begins with the items listed on the MPS and determines (1) the quantity of all components and materials required to fabricate those items and (2) the date that the components and material are required. Time-phased MRP is accomplished by exploding the bill of material, adjusting for inventory quantities on hand or on order, and offsetting the net requirements by the appropriate lead times.

multilevel bill of material

A display of all the components directly or indirectly used in a parent, together with the quantity required of each component. If a component is a subassembly, blend, intermediate, etc., all its components and all their components also will be exhibited, down to purchased parts and raw materials.

In MRP, the net requirements for a part or an assembly are derived as a result of applying gross requirements and allocations against inventory on hand, scheduled receipts, and safety stock. After being lot-sized and offset for lead time, net requirements become planned orders.

1) A released manufacturing order or purchase order. 2) An unfilled customer order.

The item produced from one or more components.

In MRP and MPS, the ability to identify for a given item the sources of its gross requirements and/or allocations. Pegging can be thought of as active where-used information.

A suggested order quantity, release date, and due date created by the planning system’s logic when it encounters net requirements in processing MRP. In some cases, it can also be created by a master scheduling module. Planned orders are created by the computer, exist only within the computer, and may be changed or deleted by the computer during subsequent processing if conditions change. Planned orders at one level will be exploded into gross requirements for components at the next level. Planned orders, along with released orders, serve as input to capacity requirements planning to show the total capacity requirements by work center in future time periods

The quantity planned to be received at a future date as a result of a planned order release. Planned order receipts differ from scheduled receipts in that they have not been released.

A row on an MRP table that is derived from planned order receipts by taking the planned receipt quantity and offsetting to the left by the appropriate lead time.

planning bill of material

An artificial grouping of items or events in bill-of-material format used to facilitate master scheduling and material planning. It may include the historical average of demand expressed as a percentage of total demand for all options within a feature or for a specific end item within a product family. Used as the quantity per in the planning bill of material.

The process of calculating the demand for the components of a parent item by multiplying the parent item requirements by the component usage quantity specified in the bill of material.

An open order that has an assigned due date.

single-level bill of material

A display of components that are directly used in a parent item. It shows only the relationships one level down

summarized bill of material

A form of multilevel bill of material that lists all the parts and their quantities required in a given product structure. Unlike the indented bill of material, it does not list the levels of manufacture and lists a component only once for the total quantity used.

The unit in which the quantity of an item is managed (e.g., pounds, each, box of 12, package of 20, case of 144).

A listing of every parent item that calls for a given component, and the respective quantity required, from a bill-of-material file.

What is a listing of all the subassemblies intermediates parts and raw materials that go into a parent assembly showing the quantity of each required to make an assembly?

Bill of material (BOM) – A listing of all the subassemblies, intermediates, parts, and raw materials that go into a parent assembly showing the quantity of each required to make an assembly.

What is the process of placing the exploded requirements in their proper periods based on lead time?

Offsetting is the process of placing the exploded requirements in their proper periods based on lead time.

Which of the following are sources of demand for products in a material requirements planning system?

The sources of demand in a Material Requirements Planning (MRP) system are the customers, suppliers, and other stakeholders.

What is netting in manufacturing?

Netting. The next step is 'netting', in which any stock on hand is subtracted from the gross requirement determined through explosion, giving the quantity of each item needed to manufacture the required finished products.
