| | Capacity Use by Planned Order (cprrp2100m000)Use this session to list the capacity use by resource or by planned order. For every operation, LN displays the capacity
use in a separate line. Therefore, if a plan item requires one resource for two
separate operations, two lines appear for the order. In the details
session, you can find the lead time and the general settings for each order
line. You can list the capacity data in three ways: - By resource, in order of date (default).
- By resource/order
number combination, sorted on operation.
- By order number,
sorted on operation.
If you list the capacity data by resource, LN displays all the
planned orders that require resource capacity. You can double-click a specific
order to view the details about the capacity it demands of the resource. For a
more general overview about capacity requirements for a specific resource,
select the Resource option from the appropriate menu, and next
the View Resource Order Plan option. Subsequently, LN starts the Resource Order Plan (cprrp0530m000) session in which LN can display all the
orders that require resource capacity for a definable time bucket. If you started this
session by zooming, you can only find and select a record. Note The data in the
current session is updated if you run the Generate Order Planning (cprrp1210m000) session or the Confirm Order Planning (cprrp1200m000) session. For each planned order, the capacity
use is only generated in the order item's fixed lead-time horizon and the resource storage horizon. Note The Capacity Use by Planned Order (cprrp2100m000) session does not contain data about the critical capacity requirements, but only the capacity use for planned orders. LN stores the data about
the critical capacity requirements in the Critical Capacity Requirements (cprmp3560m000) session from where it serves as input for
the resource master plan. Scenario The identification of an overall planning solution. Each scenario represents one overall planning solution, and
involves particular settings for the planning of items and resources. You can
use scenarios to analyze and compare various planning options and to find the
best planning solution. For example, you can vary demand forecasts or sourcing
strategies. One of the scenarios is the actual scenario, which
corresponds with the actual planning situation. You can only transfer planned
orders and production plans from the actual scenario to the execution level of LN. Plan Level The level within a hierarchical planning structure. When you plan on a higher plan level, plans are general and
less detailed. Example Plan level 1 is the highest plan level; the higher the
number, the lower the plan level. Order Type The order type for which you want to display the resource
capacity use. Operation The operation that requires
resource capacity. Plan Item The ordered plan item for which resource capacity is
required. Total Order Quantity The order quantity that you
defined in the Planned Orders (cprrp1100m000) session. Quantity Planned Input The quantity for which LN actually plans the production. The Quantity Planned Input of an operation can be greater than the
operation's Quantity Planned Output, in order to account for
material losses because of scrap and yield. The scrap quantity and the yield percentage are
defined in the Routing Operations (tirou1102m000) session. Quantity Planned Output The quantity of the main item that you expect to be output by
the operation. General Details General Resource The resource for which LN displays the capacity
use. Machine The machine at the resource of which capacity
is required. Transfer Lot Size The number of items for which an operation must be finished
before you can start with the next operation. Even though an operation is not
yet finished for all items in a production order, you can start the next
operation for the items that are already finished. The transfer-lot
quantity concept replaces the previously used concept of overlap percentage on
operation. Scrap Quantity A fixed quantity of unusable material, for example, faulty
components, or material lost in cutting or sawing operations. The gross
material requirements must be increased to account for anticipated scrap. Yield Type Determines if and how lost products come out of production if
the yield percentage is below 100%. Two yield types are available: Discrete Lost products come out of production as rejected
products. Continuous Lost products disappear completely, for example, through
evaporation.
Yield Percentage The usable output from a process expressed as a percentage
of its input. Example 1 A certain
production process for light bulbs has a yield of 98%. So, out of every 100
light bulbs produced, 98 are good on average. The remaining light bulbs are
faulty, and will therefore be rejected. Example 2 Steel wires are
twisted together to produce a steel cable. Due to the twisting, the cable is
10% shorter than the wires from which it is produced. So, the yield is set to
90%. Capacity Use Capacity Use (hrs) The sum of the average setup time and the total cycle time for the
ordered item quantity in hours. Man Capacity Setup The man capacity in hours required to set up for a
production order. LN calculates the value of this field by multiplying the value of the Man Occupation for Production of the Routing Operations (tirou1102m000) session by the value of the Production Cycle Time field. Man Capacity Production The man capacity in hours required to produce the quantity
planned input. LN calculates the value of this field by multiplying the value of the Man Occupation for Production of the Routing Operations (tirou1102m000) session by the value of the Production Cycle Time field. Machine Capacity Production The machine capacity in hours required to produce the
quantity planned input. LN calculates the value of this field by multiplying the value of the Machine Occupation of the Routing Operations (tirou1102m000) session by the value of the Production Cycle Time field. Machine Capacity Setup The machine capacity in hours required to set up for a
production order. LN calculates the value of this field by multiplying the value of the Machine Occupation of the Routing Operations (tirou1102m000) session by the value of the Production Cycle Time field. Miscellaneous Data Subcontracting Subassembly Type The type of subassembly being planned for. Subassembly An intermediary product in a production process that is not
stored or sold as an end product, but that is passed on to the next operation. For subcontracting purposes, a manufacturer can send a
subassembly to a subcontractor to carry out work on the subassembly. This
subassembly has its own item code defined in the Item Base Data. After work is finished, the subcontractor sends the
subassembly back to the manufacturer. Also this reworked subassembly has its
own item code defined in the Item Base Data. Subassembly Warehouse The warehouse from which the subassembly is sent or in which
the subassembly is received. Production Cycle Time The resource capacity required to produce the quantity planned
input. LN calculates the production cycle time by
multiplying the value of the Quantity Planned Input field by the value of the Cycle field. Lead Times Average Setup The average setup time for the operation as defined in the Routing Operations (tirou1102m000) session. Fixed Setup The time that is needed to adjust a machine before an
operation can start. This time is independent of the operation sequence. Cycle The cycle time for the
production of a single item. Wait The time that an order remains at a work center after an
operation is completed until it is moved to the next operation. LN does not plan wait times according to a specific calendar. Planning of the wait
time is based on a 7 * 24 hours week schedule. A typical example is the time required for drying after the
application of paint. Move The move time at the end of the operation. Time Unit Queue Time The time unit that LN uses to express the
queue time. Queue The date and time on which the material is needed to be able to
start the production on time. Production / Planned Start The start time of the operation. If you simulate an
order plan, LN determines
the start times and finish times of the operations by backward planning. LN plans backward based
on the extra lead-time, the safety time, and the routing of the plan item. LN starts planning backward from the
requirement date of the planned order. LN first calculates the sum of the safety time and the extra lead-time. This
results in a number of days. After the above
calculation, LN takes the
date, that is the calculated number of days before the requirement date, as the
finish date of the order. From the finish date, LN plans the start times
and finish times of the operations backward according to the routing. The last
planned operation must be ready on the finish date of the order. The length of the
period between start time and finish time equals the sum of the setup time and
the production time. LN retrieves the extra lead-time of the plan
item from the Items - Planning (cprpd1100m000) session and the safety time of the plan item
from the Item - Ordering (tcibd2100s000) session. Note You can manually
change the way an order is planned in the Planning Method field of the Planned Orders (cprrp1100m000) session. Planned Finish Date The finish time of the operation. If you simulate an
order plan, LN determines
the start times and finish times of the operations by backward planning. LN plans backward based
on the extra lead-time, the safety time, and the routing of the plan item. LN starts planning backward from the
requirement date of the planned order. LN first calculates the sum of the safety time and the extra lead-time. This
results in a number of days. After the above
calculation, LN takes the
date, that is the calculated number of days before the requirement date, as the
finish date of the order. From the finish date LN plans the start times
and finish times of the operations backward according to the routing. The last
planned operation must be ready on the finish date of the order. The length of the
period between start time and finish time equals the sum of the setup time and
the production time. LN retrieves the extra lead-time of the plan
item from the Items - Planning (cprpd1100m000) session and the safety time of the plan item
from the Item - Ordering (tcibd2100s000) session. Note You can manually
change the way an order is planned in the Planning Method field of the Planned Orders (cprrp1100m000) session. See To replan planned orders. Queue Start (Next Operation) The exact time and date of the earliest start date of the next
operation. LN calculates the queue start by adding up the value of the Wait field and the Move field to the value of the Wait Start Date field. Material Warehouse This field is only used if the order is planned by a planner,
in which case LN displays
the warehouse that the planner uses to pick up materials. | |
