Setting Up Resource Plans
To develop a resource plan, first identify key production resources. These are items required to manufacture finished goods that may limit production capacity and cannot be easily increased in the short term—for example, available funds, critical machines, and skilled labor.
You must also define resource bills, or load profiles, specifying the amount of each key resource required to produce one item unit or production plan unit.
Resource Codes
Define key resources in Resource Maintenance (21.1) with a unit of measure such as hours. The first reference for each resource should be the base or average resource capacity, in units, available per day for all workdays. Also define references for:
• Additional resources expected during the year, such as added shifts
• Temporary loss of resources, such as maintenance shutdowns
Include effective dates when these variances will occur.
Each resource can have multiple reference codes and capacities. The total capacity for a resource on a specific date is the cumulative capacity from all of the references in effect on that date.
The system calculates total capacity per month for each key resource using the workdays defined in the standard shop calendar for the site, multiplied by the cumulative resource capacity per day. Non-workdays and holidays are excluded from this calculation.
Resource Maintenance (21.1)
Resource Bills
There are two kinds of resource bills—product line resource bills and item resource bills.
Product Line Resource Bills
A product line resource bill indicates the amount of a resource required to produce one unit of the production plan.
Use PL Resource Bill Maintenance (21.5) to define each key resource.
Product Line Resource Bill Maintenance (21.5)
Quantity Per
The amount of this resource required to produce one unit of the production plan, or 1,000 currency units worth of product, stated in terms of the unit of measure defined in Resource Maintenance.
Lead Time (Months)
The number of months during which a resource is required to manufacture this product line at this site.
Offset
The number of months before the start of production that this resource is needed. This may be negative if the resource is not needed until after production is complete.
Item Resource Bills
To evaluate a manufacturing schedule, define item resource bills for each individual item to be evaluated. Indicate the amount of each key resource required to manufacture one unit of that item. Specify this amount as the Resource Quantity Per in Item Resource Bill Maintenance (21.17). Item resource bills are similar to product line resource bills, except that lead time and offset are expressed in days rather than months.
Operations planning functions use item resource bills to verify the feasibility of family and operations plans and calculate resource requirements for family item and end-item production due quantities.
