Finite Capacity Scheduling (FCS) is defined as recognizing the true
capacity limits of your shop when you schedule the capacity of your
factory's shop floor.
Advanced Planning and Scheduling (APS) extends the power of FCS
by recognizing material constraints based on both on-hand inventory as well
as your planned future deliveries from your open Purchase Orders.
JobTime's Production Scheduling products make Just-in-Time scheduling
possible for job-shops, assembly shops, and engineer-to-order. Previously
Advanced Planning and Scheduling software was limited to repetitive,
standard, high-volume and make-to-stock production. JobTime extends
the Just in Time manufacturing principles into additional environments.
For Finite Capacity Scheduling, resource capacity limits include the
following:
 | Recognition of constraints on which alternate equipment work stations
(or labor operators) can perform certain jobs |
 | Recognition of both a fixed setup time as well as a quantity dependent
variable process time on each operation step. |
 | Recognition of multiple resource constraints demanded by the same
operation such as equipment, tools, labor. |
 | Recognition of a variable crew size, fractional or multiple resources
required, per operation. |
 | Recognition of a split factor (number of splits allowed) per operation
across multiple work stations of the work center. |
 | Re-sequence jobs to group setup matches
between orders for optimal efficiency |
 | Earliest time-of-day to allow an operation to start, which can vary by
part & routing (reflects constraints such as heat, humidity, light, or to
limit work to specific shifts within the calendar) |
 | Latest time-of-day to allow an operation to start, which can vary by
part & routing (reflects process cut-off timed, or shift preferences
by part, within the work-center calendar) |
 | Resource seized and held during a series of consecutive operations (same
operator throughout a series of tasks, avoid inter-stage obsolescence, or to
guarantee downstream capacity). |
JobTime Systems, Inc. (JSI), announced the world's first simulation-based
Finite Capacity Scheduling system in August, 1984. Since that
time, JSI has specialized in scheduling software to improve
manufacturing on-time performance, and supports all current popular
philosophies of scheduling.
JobTime has been applied successfully in discrete, repetitive, process,
engineer to order and assemble to order manufacturing.
JobTime also gives you the modeling power you will need for Advanced
Planning and Scheduling without forcing
you to learn computer programming. We can show the typical shop
scheduler, with 3 days of basic training,
how to to accurately model your shop constraints for any
environment, including make to order, assemble to order, engineer to order,
and process manufacturing operations.
JobTime also supports longer range
Advanced Planning and Scheduling (APS) . APS
supports the supply chain, because it can see customer forecasts, vendor
deliveries, and assured scheduling that will synchronize both material and
capacity constraints over a long-term planning horizon. Forecast
demand and/or planned orders can be input from either ERP or JobTime's own
JobPlan
module to generate future work loads of 12 to 18 months into the
future.
All JobTime scheduling products are Y2K compatible
and give detailed scheduling on each
operation step of every work order, even down to the minute, while
recognizing multiple resource constraints, and sequencing to optimize and
group like setups in bottleneck work centers.
JobTime's Advanced Planning and Scheduling can recognize
BOM make-item assembly constraints, ERP
material supply pegging allocations, all with
supporting activity drill-down, accurately planned even down to
the minute.
JobTimeŽ 5 is also fast, scheduling a
true 30,000 detailed operations per minute
on today's 2.0 Gigahertz PC's.
Computer speeds will vary with the complexity of modeling, and the total
number of events required to fully process all the aspects of each
operation.
JobTime helps you rapidly model the most detailed and challenging
scheduling problems, without the need for complex computer programming,
because JobTime modeling is based on standard data entry screens to select
and enable features. Please see our
