Requirements for this Tutorial

What you should successfully master

The basics of SAP and be.as Good knowledge of general manufacturing processes


Learning Targets

After working through the lesson, you will be able to:

Create and manage parallel resources


Agenda

Parallel resources

1: Introduction

2: Tool with same start/end date

3: Parallel resource with the same start/end date

4: Alternative parallel resources

4: Overlapping operations


Parallel resourceaIntroduction

What are parallel resources?

Resources, that must be used at the same time.


Parallel resource Types of parallel resource

be.as offers the following types of parallel resources:

Tools with the same start and end date.

Parallel resources with the same start and end date, with any degree of utilization.

Alternative parallel resources.

Overlapping work sequences.


Parallel resource Tools

Tools are always available 24 hours, there is no shift calendar

To restrain availability use the switch „blocked until“ in the tools master sheet

Tools are only taken into consideration, if capacity planning is activated


Parallel resource Tools : setup

Insert tools in the routing in tab „tool“.

Now the routing can be scheduled only at times when the tools are available.


Parallel resource Tools : setup a parallel alternative tool

Insert a parallel alternative tool by enabling the switch : defines cycle time“.The expected time is deposited in the tool and transferred to the work sequence when activated.

In the structure view as well as in the APS view you can switch between tools. Automated optimization or tool selection is not possible.


Agenda

Parallel resources

1: Introduction






Parallel resourcesgeneral

Setup the parallel resource in routing: tab “parallel”

With a parallel resources, a work sequence can be processed on multiple resources in parallel. Example: machine and employee or a several machines. Parallel resources as well as the operation itself can be logged on and logged off. All parallel resources always have the same start and end date. Therefore no separate job time or setup time is possible.

The degree of utilization is adjustable, if you set to 50%, with a lead time of 1 hour, the resource will be loaded with 30 minutes.


Parallel resourcescapacity check

If the degree of utilization is set to 100% and the resource limits are checked according to resource master sheet, then the operation can only be dispatched at the time, when both the main resource and the parallel resource are available.

If you set a degree of utilization different from 100% or there are more than 1 employe/machine available for this resource, then only the daily capacity is checked. (Check to prevent utilization of more than 100%)


Parallel resourcesAPS view

In the APS parallele resources are displayed in the lower domain. To activate: tab „Resource“ - switch „resource“


Parallel resourcesdifferent shift schedule

If for the main and the parallel resource different shift schedules are existing, the schedule with the later start date is used.

Example: Main resource (machine) 0:00Operator (employee): 8:00Time is reserved from: 8:00


Agenda

Parallel resources

1: Introduction






Parallel resourcesAlternative parallel resources

Parallel resourcen can also have alternative resources.

Example:

To the machine „1202“ employee group „INJ_INT“ as well as „INJ_EXT“ can be assigned.

To do so, enable the switch „alternative“ at all concerning resources.


Parallel resourcesAlternative parallel resources

In the work order, you can select the parallel resource.

Restrictions: you can have an unlimited number of parallel resources and ONE alternative-parallel resource


Parallel resourcesAlternative parallel resources: optimization

be.as scheduling function allows to optimize parallel-alternative resources. Enable „optimization“ in the work sequence. Under consideration of existing time reservations, the parallel resource with the shortest lead time is used. For further information see training unit „resource optimization“


Agenda

Parallel resources

1: Introduction






Parallel resourcesOverlapping operations

Usually the following operation starts when the previous one is finished.The overlap limit determines how long after the start of the first operation, the second one can be started in parallel. In the given example, the second operation starts one hour after the first ended.


Parallel resourcesOverlapping operations: APS view

In the APS view overlapping is displayed: one hour in this example. Overlapping operations may have different lead time. The following operation can start at the earliest: start date + overlap limit of the previous operation.

If there is no time available for the overlapping operation, the overlapping limit is ignored and the next empty time frame is used.


Parallel resourcesOverlapping operations: restrictions

Restrictions:

-Calculation of overlapping operations works only with forward scheduling

-If the lead time (overlapping operation + overlap limit) is shorter than the lead time of the main operation, a correct computation is not possible.

-If capacity limits are taken into account and there are not enough resources available, the overlap limit is ignored.


Summary

You can now: Create and manage parallel resources
