Introduction to SiCluster Multiline

2.1

2.1 What is SiCluster Multiline?

What is SiCluster Multiline?

SiCluster Multiline is a key component for program-controlled production planning.

SiCluster Multiline is used to determine the most efficient distribution of specified recipes/jobs across an

available quantity of lines. Based on an optimized product/recipe line allocation, you can then cluster

within the lines with the help of SiCluster Professional and optimize the result setups (cluster).

SiCluster Multiline therefore enables you to distribute numerous recipes/jobs across multiple lines, there-

by making it easier for the downstream optimization steps with SiCluster Professional and the result job

optimization to find good solutions.

SiCluster Multiline is designed to achieve the following goals:

▪ Even utilization of lines

▪ Lowest possible overall production time across all lines

▪ Lowest possible number of setups required to produce the recipes/jobs

2.2

2.2 Who is SiCluster Multiline Designed For?

Who is SiCluster Multiline Designed For?

SiCluster Multiline is particularly suitable for the three following areas of application:

1. Medium to long term capacity planning for fixed family setups

2. Evaluation of "what if" planning scenarios

3. Short term distribution and clustering of upcoming production jobs

Medium to long term capacity planning for fixed family setups

In this case, the customer has medium to long term advance planning for the expected production jobs.

This could, for example, include advance planning for the next three to six months.

SiCluster Multiline is used to optimize the allocation of production jobs to the production lines. This allo-

cation is then fixed for a longer period. The aim is to produce as many production jobs as possible in

fixed setups. The software takes into account the prescribed restrictions and creates an even distribution

of the production volume across the lines.

You can also check whether the line capacity currently available is sufficient to cover the expected ad-

vance planning volumes for a certain period.

Evaluation of "what if" planning scenarios

SiCluster Multiline is suitable for so-called "what if" planning scenarios.

These planning scenarios are needed in case changes must be made to the production capacity or line

configuration.

Examples of "what if" planning scenarios:

▪ Can the expected production volume be produced with the current shift plans or are additional shifts

required?

▪ Could we shut down line X for the next two months?

▪ What would be the advantage of replacing an old line with a new SIPLACE line?

▪ Is is advisable to remove machines from line X, in order to extend line Y, Z?

Short term distribution and clustering of upcoming production jobs

The two above mentioned application cases focus on using medium to long term advance planning.

However, SiCluster Multiline is also suitable for short term planning if you already know the upcoming

production jobs for a certain planning horizon e.g. for several days or a week.

The aim is to produce all production jobs with as few setups as possible in the shortest possible time.

In these cases, flexible family setups are used, which are then only used for producing the current pro-

duction jobs. The allocation to these production lines is flexible. The next time, SiCluster Multiline could

allocate the production job for the same product to a different line.

2.3 Benefits of SiCluster Multiline

Benefits of SiCluster Multiline

SiCluster Multiline offers the following benefits:

▪ Even utilization of lines.

▪ Minimum overall production time across all lines.

▪ Lower number of different components across all lines.

▪ An improved initial situation for calculating constant tables (with SiCluster Professional).

▪ A reduced number of required setups and hence a reduced number of required feeders and tables.

▪ More boards in the family setup / fixed setup and thus fewer changeovers.

▪ Less manual planning required by the production planner.

▪ The quality of the planning results depends less on the experience of the production planner.

2.4

2.4 What Does SiCluster Multiline Do?

What Does SiCluster Multiline Do?

▪ SiCluster Multiline calculates an allocation of recipes to lines with high component overlap across

the boards on the line.

▪ SiCluster Multiline distributes the recipes on the condition that the prescribed line production time is

not exceeded.

▪ SiCluster Multiline enables you to plan up to 1000 boards or 2000 board sides (top+bottom), for up

to 10 lines.

▪ SiCluster Multiline supports various different setup concepts for the lines at a factory at the same

time e.g. changeover tables.

▪ SiCluster Multiline uses existing constant tables in a line.

▪ SiCluster Multiline takes into account user-defined rules:

– Inclusive groups for recipes

– Exclusive groups for recipes

– Production of recipes on the same line

– Line exclusions and binding (defined by prohibited production of specific recipes on certain lines)

▪ SiCluster Multiline takes into account the process requirements for the products and the process ca-

pabilities of the lines.

▪ In an integrated process, SiCluster Multiline supports in-line cluster formation with SiCluster Profes-

sional and the optimization of result setups (cluster) with the SIPLACE Optimizer.

2.5

2.5 What Does SiCluster Multiline Not Do?

What Does SiCluster Multiline Not Do?

▪ SiCluster Multiline does not perform optimization or specify the order in which products are to be pro-

duced.

▪ It does not take into account the production dates or production sequence priorities.

▪ It does not include urgent production jobs in the plans for existing setups which were created with

previous plans.

2.6

2.6 The SiCluster Multiline Optimization Process

The SiCluster Multiline Optimization Process

The SiCluster Multiline optimization process consists of three steps:

1. SiCluster Multiline creates an optimized list of allocated production jobs for each production line.

2. The results of this line allocation are used by SiCluster Professional on each line, for the clustering

of family setups.

3. In the last step, the grouped setups and recipes are optimized with the SIPLACE optimizer.

NOTICE

SiCluster Multiline is an important, high-performance extension to the existing setup planning

and optimization tools. However, SiCluster Multiline does not replace either of these tools.
