  system, because it is also used extensively in 
  job-shops, engineer-to-order and assemble to
  order shops.
• - JobTime Website
• Can be incorporated into work into a high mix-low
  volume company.

11
Constraint Handling

• Deals with multiple constraints
• Equipment
• Tools
• Labor
• Supplies
• Floor Space
• Accounts for Setup times
• Fixed
• Variable

12
Accurate Shop Conditions

• Allows alternate routes
• Allows for what-ifs to elevate bottlenecks.
• Recognizes the use of multiple resoures
• Will seize and hold if resource not available
• Recognizes fixed as well as quantity dependent
  variable process times

13
Scheduling Capabilities

• Customize up to 4 shifts
• Programmed shift patterns
• Every workstation has its own calendar, setup,
  and efficiency

14
Product Routing and Sequencing

• Routings
• Defined by operations
• Single or multiple routings for each part can be
  generated
• Work orders can be generated from routings
• Scheduling
• JobTime can consider
• Preferred workstations
• Resource constraints Seize and release
• Designed to minimize setup

15
Forecasting

• Recognizes trends and seasonality for
  manufacturers with standard products

19
Explicit Assembly Constraints

• Offers a finite Scheduling feature that schedules
  the work orders in correct sequence
• Schedule should not show an assembly to start
  prior until all subassembly work orders are
  completed
• Saves hundreds of hours of manual checking and
  rescheduling effort.

20
Production Costing

• Reflects costs down to individual operations
• Each work order can reflect a unique production
  cost that can expresses special handling or
  processing in any operation step.
• Supports cost engineering by providing values
  down to the operation level for
• Budget
• Actual
• Earned value

21
Score Cards Reports

• Measures of performance are calculated after each
  schedule and retained in a special score card
  file.
• Measures
• Make Span
• of Jobs Late
