JALLIB processing: Scheduling

SCDRMNTIM: Take into account the remaining time

This entry point is used to intervene in the remaining time taken into account in the scheduling (setup and operation).

Context and operating mode

On reading each operation in the scheduling.

Available screen and file classes

The MFO, SCH, MFG and ITF classes are on-line.

Use

This entry point has been designed to make it possible to intervene in the remaining time of each operation.

The code is the following:

#---------

# EP to modify the remaining time

# PE if GPE = 1

GPE = 0

GPOINT = "SCDRMNTIM"

Gosub ENTREE From EXEFNC

#---------

If !GPE

WSETTIM( I) = [F:MFO]EXTSETTIM - [F:MFO]CPLSETTIM

WOPETIM( I) = [F:MFO]EXTOPETIM - [F:MFO]CPLOPETIM

WOPTTIM( I) = WSETTIM(I) + WOPETIM(I)

Endif

The WSETTIM( I), WOPETIM(I) and WOPTTIM(I) variables can be loaded by the entry point in substitution for the standard loading (GPE=1).

Open tables

In the table below, the significant content flag indicates that the content is in phase with the context (…).

Table	Significant content	Table Title
MFGHEAD	Yes	OF
MFGOPE	Yes	WO operations
SCHEDULING	Yes	WO scheduling data
ITMFACILIT	Yes	Product-site
FACILITY	Yes	Sites

MATUPDDIS: De-activation of the material updates

This entry point is used to de-activate the update of the material requirement dates during the scheduling.

Context and operating mode

Before the update of the WO according to the results of the scheduling.

Available screen and file classes

The MFG class is on line.

Use

This entry point has been designed to make it possible to de-activate the update of the materials (requirement dates) within the scheduling process.

To proceed with this de-activation, set the global variable GPE to 1.

Since V6.5: three variables allow to omit the update of dates as a result of the scheduling.

• WNO_UPDMAT is assigned with the GPE result in order to indicate "no update of dates on components/sub-products"
• WNO_UPDOPE can be set to 1 in order to indicate "no update of dates on operations"
• WNO_UPDWOF can be set to 1 in order to indicate "no update of dates on WO/released products"

WARNING: Make sure to test from what function this EP will be triggered to ensure it does not disinhibit all the scheduling cases. To identify the context (calling function), test the global variable GFONCTION.

 

Open tables

In the table below, the significant content flag indicates that the content matches the context (…).

Table	Significant content	Table Title
MFGHEAD	Yes	OF
MFGOPE	No	WO operations
MFGMAT	No	WO materials
SCHEDULING	No	WO scheduling data
ITMFACILIT	No	Product-site
FACILITY	Yes	Sites

 

INITSCD: Scheduling initialization

This entry point is used to initialize certain scheduling variables, especially the size of the calculation table that limits the maximum duration of a production.

Context and operating mode

This entry point is called as soon as the scheduling sub-program is open.

Available screen and file classes

The JALK class is on line.

First use

This entry point has been designed to allow the modification of the scheduling calculation horizon's size.

This horizon is expressed using the OFFSETCAL integer variable (set by default to 200). This margin limits the maximum duration of a production. Beyond this threshold, the operations are no longer scheduled.

The margin can be extended using this entry point in order to process specific cases of production that are particularly long.

Second use

The preparation and post-operation time does not take into account the capacities of the work centers.
Addition of 3 variables in order to activate a function calculation of the work center's capacities.
WPRPCODCAP,WPSPCODCAP,WWAICODCAP set to 0 by default. They should be set to 1 in the INITSCD EP in order to use the capacities.

ENDSCD: End scheduling

This entry point is used at the end of the scheduling of planned and firm WOs just after the update of the tables.

Context and operating mode

This entry point is called after the table update in the scheduling sub-program.  

Available screen and file classes

The JALK class is on line.

 Use

This entry point is used at the end of the scheduling.

It is located just after the update of the tables and just before the Commit instruction. 

INIT_JAL: Scheduling initialization

This entry point is used to intervene in all the operations loaded in memory, before the calculation of the scheduling, in order to intervene on specific values.

Context and operating mode

This entry point is used to intervene in the list of operations loaded in memory.

$ACTION

Case ACTION

When "INIT_JAL":Gosub INIT_JAL

Endcase

Return
