Advanced Modeling and Constraint

To precisely meet the various demands of the manufacturing industry, it is required to be highly expressive and to provide efficient modeling of enormous data. FLEXSCHE has the big advantage of flexibly combining multiple functions to meet these requirements. In this page, we introduce a few parts of functions which are provided to express advanced modeling and constraints.

Note: Even more advanced and specific functions are provided as Advanced Options.

Line Constraints / Resource Connection Constraints

This can restrict the combinations of assignable resources between upstream and downstream processes. "Line Constraints" simply defines the belonging line for the resource. "Resource Connection Constraints" can provide complicated constraints such as restricting only specific processes or putting constraints on subsidiary resources.

Parametric Process Definition

Parametric Process DefinitionParametric Process Definition

If the process graph for manufacturing a certain product is similar to the graph for another product, this can share common parts so that only differences need to be separately defined. This reduces the volume of data and simplifies maintenance. Furthermore, the method of calculating qty. can be customized in various ways when you generate operations from orders.

This can easily specify the combinations of resources which one operation uses at the same time. For example, it is convenient for the case where operators are fixed to each equipment.

Operation time can be defined by using an expression. This can express such cases as the manufacture time complexly changes by the qty. to be manufactured.

Concurrent conditions / Simultaneous loading constraint

Concurrent conditions is a constraint in which the operations under the identical conditions can be executed in the same time zone. In simultaneous loading constraint, additionally, the operations must start and end at the same time.

Dymanic Item Selection

Dymanic Item Selection

Items to be used by operations or items to be generated as by-products can be determined by expressions when the operations are assigned. For example, you can switch the material items depending on the resources to assign.

Process Template and Item Recipe

If the process definition can be patterned, this simplifies data maintenance by sharing templates from multiple process definitions and by only describing the differences. (Process Template)

Expressions which can be described in various places in FLEXSCHE would be a useful weapon to achieve flexible operation, modeling and scheduling.

  • All sorts of evaluation values and conditions in a scheduling rule
  • All sorts of constraint conditions and capacity and such in master data
  • Designations of display colors and display strings of a chart
  • Chart rows configuration rules
  • Designations of a file path
  • Display content and filter/sort conditions on FLEXSCHE Editor
  • Data mapping on FLEXSCHE EDIF, etc.

FLEXSCHE is rich in user interface to input expressions.
