Definition
A resource that is part of the Advanced Resource Management (ARM) system.
A specified condition of a resource or group property that gets saved. A filtering condition becomes a component of a quantity expression. It is thus the smallest (atomic) component of a resource requirement. When applied during the simulation run, the filtering condition limits the collec- tion of resources to those that meet the condition.
A means for organizing resources. Groups can be used to control which types of resources are allocated to and released from items. Although a resource can only belong to one pool, it can be a member of many differ- ent groups.
A method for distinguishing one resource, group, pool, or item from the others.
A component of a resource requirement that specifies the desired number of resources to be selected from a list of those that meet the filtering con- ditions. A resource requirement has a quantity expression that consists of a specified quantity of one or more filtering condition results.
The means by which process activities and operations are performed. Typical resources include equipment, personnel, space, energy, time, and money.
A request by an item to satisfy a resource requirement. This causes the Resource Manager to assign the item a unique Resource Order ID.
The location (record index) of a resource order in the Orders database table.
A means for organizing resources. Pools can be used to control which types of resources are allocated to and released from items, as well as to capture statistics. A resource can only belong to one pool but it can be a member of many groups.
A named rule that specifies how many of what types of resources to allo- cate to an item. The rule could be simple (1 washer/waxer is required per car) or it could be a complex expression involving several resources, groups, and so forth. A resource requirement can be composed using one or more quantity expressions.
