Operation resources

Operation resources are used to model the capacity consumption of an operation.

Field

Type

Description

operation

operation
Operation loading the resource.
This is a required field.

resource

resource
Resource being loaded.
This is a required field.

skill

skill
Skill required of the resource.
This field is optional.

quantity

double
Required quantity of the resource.
The default value is 1.0.
The use of the value is different per resource type:
  • Type ‘default’:
    The resource is used during the complete duration of the manufacturing order.
    If the resource has a size of 1 and the operationresource record has a quantity of 1, then only 1 operation can be planned in parallel.
  • Type ‘time buckets’ and ‘quantity buckets’:
    The total capacity consumed by a manufacturing order is equal to the (quantity_fixed + quantity * manufacturing order quantity) / efficiency.
    This quantity is consumed from the capacity bucket where the manufacturing order starts.

quantity_fixed

double
For a resource of type ‘time buckets’ or ‘quantity buckets’ the total capacity consumed by a manufacturing order is equal to the (quantity_fixed + quantity * manufacturing order quantity) / efficiency.
The default value is 0.0.

effective_start

dateTime
Date after which the resource load is valid.
Before this date the planned quantity is always 0.

effective_end

dateTime
Date at which the resource load becomes invalid.
After this date (and also at the exact date) the planned quantity is always 0.

priority

integer
Priority of the load, used in case of alternate load.
The default is 1. Lower numbers indicate more preferred loads.

name

non-empty string
Optional name of the load.
All loads with the same name are considered to be alternates of each other.

setup

non-empty string

Name of the required setup on the resource.

search

string
Defines the order of preference among the alternate loads.
The valid choices are:
  • PRIORITY
    Select the alternate with the lowest priority number.
  • MINCOST
    Select the cheapest resource.
  • MINPENALTY
    Select the alternate which gives the lowest penalty.
    Building before the requirement date incurs a penalty, so this mode favors resources that are readily available.
    This is the default.
  • MINCOSTPENALTY
    Select the alternate which gives the lowest sum of the cost and penalty.

On default resources the resource is used during the complete duration of the operation.

On bucketized resources the capacity is consumed from the capacity bucket at a single moment of time. Different loading policies can be specified:

  • default:
    By default capacity is consumed at the start of the operation.
  • load_bucketized_end:
    A load of this type that loads a bucketized resource at a specified offset from the end date of the operation.
    An offset of 0 means loading the resource at the end of the operation.
    An offset of 1 day means loading the resource 1 day before the operation end date. If the operation takes less than 1 day we load the resource at the start date.
    The offset is computed based on the available periods of the operation, and skips unavailable periods.
    THIS FUNCTIONALITY IS NOT AVAILABLE IN THE USER INTERFACE, AND IT IS ONLY IN BETA STATE IN THE PLANNING ENGINE.
  • load_bucketized_start:
    A load of this type loads a bucketized resource at a specified offset from the start date of the operation.
    An offset of 0 means loading the resource at the start of the operation.
    An offset of 1 day means loading the resource 1 day after the operation start date. If the operation takes less than 1 day we load the resource at the end date.
    The offset is computed using the available periods of the operation, and skips unavailable periods.
    THIS FUNCTIONALITY IS NOT AVAILABLE IN THE USER INTERFACE, AND IT IS ONLY IN BETA STATE IN THE PLANNING ENGINE.
  • load_bucketized_percentage:
    A load of this type loads a bucketized resource at a percentage of the operation duration.
    An offset of 0 means loading the resource at the start of the operation.
    An offset of 100 means loading the resource at the end of the operation.
    The calculations consider the available periods of the operations, and skip unavailable periods.
