JobTime® 5 - Level 2
In addition to the strong Level 1 features, at Level 2 you will move up to stronger scheduling capabilities with the following:
 | Explicit Work Stations |
| Preferred Work Stations w/ Efficiencies |
| Setup Matching with Exact Setup Matches |
| Overlapping Operations- Multiple Strategies |
| Secondary Resources / Infinite Demand |
| Multiple Resource Constraints (Labor, Tools) |
| Finite/Infinite Secondary Constraints |
Explicit Work Stations. Each work center contains one or more work stations. Most commonly, work stations correspond to machines, or work benches, and represent places where work is being done. When you define Work Centers, you can define the work stations as "Implicit" by simply entering a number, representing the number of work stations active within that work center, shift by shift. Explicit Work Stations, on the hand, are defined with explicit records, to show their names, and other information about them, including an relative efficiency factor and a calendar which might be specific to that work-station.
On the left screen below, you can see an example of defining 2 work implicit work stations for the PAINT work center. On the right, you see an example of 4 Explicit Work Stations defined for the PROD work center:

Preferred Work Stations. When we define a number of work stations, sometimes we want to route all tasks to the work center, and have the scheduling system assign tasks to work stations in the most efficient manner possible to maximize work center utilization. But other times, some work can only be done on a subset of the work stations. In the Plant Example above, only Station C and D can make large size pieces. Another example is that only Station-A has the ability to make parts with 0.0001 inch tolerance, and some work orders will require this precision.
To recognize your need for 'Preferred Station' constraints, JobTime® 5 lets you assign these constraints to individual operations of specific work orders, to be certain the Operations of these Work Orders will only be performed on one of the allowed Work Stations. In the following example on the left, we restrict the PROD operation to be performed only on Station C or D. On the right, we restrict the PROD operation to be performed only on Station A:
