Multi-level routings

The routing code describes the process involved in manufacturing (producing) or processing a product. It provides the sequence of operations and tools that are involved in producing or processing a particular product.

The routing code matches the product code. The product code can be a manufactured product, which is defined as a bill of material, or a generic reference to a parent routing, which is linked to several products.

The major version of the routing. Major versions might be used where there have been increased or significant changes in functionality. The "form, fit, or function" has changed.

The numeric code associated with a production BOM.

Multiple bills of material (BOM) can be defined for a single product. Each BOM code can be assigned specific management features. For manufactured or subcontracted products, this includes restriction of the BOM to a specific site and to specific areas of functionality such as for costing or for capacity planning.

The major version of the production BOM. Major versions might be used where there have been increased or significant changes in functionality. The "form, fit, or function" has changed.

Lot size.

The lot size is used in the MRP (Material Requirements Planning) calculation. According to the reorder policy, you can perform the following actions:

• Split a global suggestion into several lots, respecting manufacturing constraints such as vat size.
• Round up the requirement to the minimum quantity when the lot size is fixed, respecting purchase constraints such as box capacity.

The status on the shop floor of the preparation of the operations and tools in the routing.

In development: The routing is not yet complete.

Available to use: The routing is complete and the coherence of the routing operations was validated.

The production operations and operation resources at each level in the routing. Icons symbolize the various elements of the routing operations. They provide a quick visual reference to the element.

Routing operations are supported using a color indicator so that you can easily spot if the operation time that's applied to the production time is fixed or proportional. Icons distinguish the machines, labor, and tools in the routing.

Identifies the production resource to use for the operation. This work center is the main or principal work center for the operation.

The resource can be a machine, a labor, or a subcontract work center. Operation scheduling considers the availability of the work center. You can specify the number of operators to allocate to it however you cannot allocate more resources than that defined on the work center record.

Identifies the type of operation that's performed on the work center. This might be a machine, a labor, or a subcontracted operation.

Subcontracting type work centers are managed externally by subcontract suppliers.

Specifies a fixed amount of time needed to prepare a work center.

It’s part of the work center load. It’s expressed in either the time unit specified in the routing header or in the standard operation, if a standard operation was applied for the operation. The time can be zero.

The time needed to manufacture the product described in the routing.

The operating time:

• Is defined in hours or minutes (routing Time unit field)
• Is expressed for 1, 100, 1,000, or a lot of units of the operation based on the management unit

• Can be proportional or fixed based on the operating time type

  Example

  Time unit = Hours
  Time type = proportional
  Management unit = Time for 100
  Operating time = 2
  Operating unit = kg
  Finished product unit = un
  REL-OPE conversion coefficient = 0.5
  The operation time is equal to 2 hours for 100 kg. If a work order is created for 1,000 units of the finished product, the time needed for the operation is 10 hours to obtain 500 kg.

Post operation, or post run time is a "deadline" that occurs after waiting time. It's non-productive time.

Post run time is not applied to the work center load. It's typically "transfer time", or a transition period from one work center to the next work center that occurs after a process was completed on a machine and until the machine can next be used.

If operator time is needed for an operation during the post run time, you should add a new operation to the routing. An operator might be needed, for example, for the transportation or carriage, or the transition between 2 work centers. The additional operation needs to be for the appropriate resource type, such as "carrier".

When scheduling time for these resources if, for example, a machine or labor work center runs from 08:00 to 12:00 and from 13:00 to 17:00 with a 1 hour break from 12:00 to 13:00:

• When scheduling post run time, a neutral 24 hour calendar for the defined resource is applied. Post run time is not, therefore, interrupted by the 1 hour break.
• When scheduling time for the additional resource, the calendar for the defined resource is applied. Time will be interrupted by the 1 hour break.

If the operation requires an "emergency release", a reduction coefficient can be assigned that makes it possible to completely remove any post run time.

Waiting time is "delay time" that occurs after an operation. It’s non-productive time.

Waiting time is not applied to the work center load. It's for periods such as drying time or cooling time that occurs after a process was completed on a machine and until the machine can next be used.

If machine time is needed for an operation during the waiting time, you should add a new operation to the routing. A machine might be needed, for example, for drying or cooling components at a work center. The additional operation needs to be for the appropriate resource type, such as "cooler".

When scheduling time for these resources if, for example, a machine or labor work center runs from 08:00 to 12:00 and from 13:00 to 17:00 with a 1 hour break from 12:00 to 13:00:

• When scheduling waiting time: If the resource needs to be available, the calendar for the resource also applies to the waiting time. For this example, time will be interrupted by the 1 hour break.
• When scheduling time for the additional resource: The calendar for the defined resource also applies to the waiting time. The additional resource time will be interrupted by the 1 hour break.

Preparation time is "waiting time" set at the start of an operation.

Preparation time is not applied to the work center load.

Although preparation time is waiting time, it can be used for the time it takes to prepare for an operation on a work center. This might be time for settling liquids or cleaning a machine. When preparation time is used for setting time at the start of an operation, the resource needs to be available.

When scheduling preparation time, the calendar for the defined resource is applied. This means that if, for example, a machine or labor work center runs from 08:00 to 12:00 and from 13:00 to 17:00 with a 1 hour break from 12:00 to 13:00, preparation time will be interrupted by the 1 hour break.

If the operation requires an "emergency release", a reduction coefficient can be assigned that makes it possible to completely remove any preparation time.

Defines how time for the operations in the routing is expressed. The time unit can be hours or minutes.

The time applies to the setup time, run time, and the rate of all operations in the routing.

Work order operation quantities are expressed in the operation unit. Use the operation unit to express the operating time in a different unit to that of the product being produced by the routing.

The operation time type applied to the production time entry.

Proportional: The production time is proportional to the released quantity. It’s expressed in hours and minutes, as based on the time unit for a given number of units, which is based on the management unit and base quantity.
With a proportional time type, the production time is entered in the operation time section. The rate section cannot be assigned.

Rate: The production time is proportional to the released quantity. The rate is used to express the time in number of units per hour or minute, depending on the time unit.
With a rate time type, the production time is entered in the rate section. The operating times, management unit, and basic quantity cannot be entered.

Fixed: The production time is independent of the released quantity. This time is expressed in hours or in minutes depending on the management unit.
With a fixed time type, the production time is entered in the operating time section. The management unit, basic quantity, and rate cannot be entered.

Depending on the resource being used, the number of decimals for the operation time can be insufficient to express the production time.

The management unit makes it possible to express the operation time for 1, 100, 1,000, or a lot of units of parts to be produced.

Indicates if the component is stored in stock.

Physical: This is a physical component. Quantities are stored in stock.

Active: This is an active component such as nails or staples. Quantities are not stored in stock.

Identifies the level that you select in the routing hierarchy:

• The finished product or the subassembly product
• The operation sequence number
• The production resource to use for the operation. The resource can be a machine, a labor, or a subcontract work center.

Specifies a fixed amount of time needed to prepare a work center.

It’s part of the work center load. It’s expressed in either the time unit specified in the routing header or in the standard operation, if a standard operation was applied for the operation. The time can be zero.

The time needed to manufacture the product described in the routing.

The operating time:

• Is defined in hours or minutes (routing Time unit field)
• Is expressed for 1, 100, 1,000, or a lot of units of the operation based on the management unit

• Can be proportional or fixed based on the operating time type

• When scheduling time for the additional resource: The calendar for the defined resource also applies to the waiting time. The additional resource time will be interrupted by the 1 hour break.

The base quantity depends on the management unit.

In effect, if the time is expressed for 1 unit, for 100 units or for 1,000 units, the base quantity is forced, respectively to 1, 100 or 1,000 units.

However, if the time is expressed for a lot, the base quantity can be entered. If the processed routing code is assigned to a site, it's initialized for the lot size of the product-routing for the site.

The base quantity entry format depends on the operation unit.

Post operation, or post run time is a "deadline" that occurs after waiting time. It's non-productive time.

Post run time is not applied to the work center load. It's typically "transfer time", or a transition period from one work center to the next work center that occurs after a process was completed on a machine and until the machine can next be used.

The management unit makes it possible to express the operation time for 1, 100, 1,000, or a lot of units of parts to be produced.

Identifies the type of operation that's performed on the work center. This might be a machine, a labor, or a subcontracted operation.

Subcontracting type work centers are managed externally by subcontract suppliers.

Indicates if the operation is subcontracted to an outside company. Subcontract is the term used to describe the purchase of a service for carrying out an operation for a work order.

No: The operation is never subcontracted.

Normal: The operation is always subcontracted. The factory does not have the required skills or toolings. The main (principal) subcontract work center is assigned as the subcontract work center.

By exception: The operation is carried out internally. It can be subcontracted in exceptional circumstances such as when instances of overload or temporary issues occur.
