Setup time matrix
Products and product-site records used in your manufacturing processes are classified using a list of common identifiable characteristics defined as attributes. When a product being used in your manufacturing process is changed for a different product a time factor can be involved in setting up a work center for the new product. Whilst you can define setup time for a work order operation, if a single work center is used for different products with matching attributes you can use a setup time matrix to define setup time between individual characteristics, or attribute values in the assigned attribute classifications. For example, you want to define the time it takes to set up a work center to spray paint white colored products after cleaning the spray system which had been used to paint blue colored products. You use this function to create a matrix that can be used by your web scheduling solution that defines the time that it takes for work centers to be set up ready for use where the products used at a work center have associated subsets of attributes. This setup time matrix is fed into your web scheduling solution to optimize setup time between operations by organizing the sequence of production to minimize the setup time between products and operations. For the previous example, your web scheduling solution can use a setup time matrix to organize the sequence of operations carried out in your paint booth to minimize the setup time between switching from one paint color, and cleaning the work center to set it up for a different paint color.
Attributes, and the setup time matrix are only used with your web scheduling solution. They are not used with work orders or Production Scheduler
Prerequisites
Refer to documentation Implementation
Screen management
The Setup time matrix function contains a home section in which you define an attribute classification, and a table in which you define exceptions between individual entities associated with the defined attribute classification.
Header
You use this section to create a setup time matrix for a specific attribute classification with the default times for setting up both different, and the same attribute value characteristics defined for the classification.
For example, your company manufactures bicycles. A common attribute is color. You can define the time it takes to set up work centers to paint the bicycle frames when the paint color is changed, or a work center is cleaned and the same color used.
Block number 1
| Matrix code (field MATCOD) |
|
Use this field to identify this attribute classification setup time matrix. |
| Matrix description (field MATDESAXX) |
|
Use this field to identify this setup time matrix. |
| Attribute (field ATTCOD) |
|
Use this field to identify a standard classification, or characteristic of a product that can be referenced by your web scheduling processes. For example, if a product is painted during your manufacturing process, an attribute classification might be "PAINT" or "COLOR". |
| Attribute description (field ATTDESAXX) |
|
This field identifies the standard characteristic that you have classified as a product attribute. |
Default setup times
| Different attributes (field DEFSETTIM) |
|
Use this field to define the default setup time between individual characteristics, or attribute values of the defined attribute classification. The value can be zero. For example, a work center is used for multiple products with the same attribute classification such as paint. Cleaning the work center to change from one paint color to a different color takes the same length of time for every change of color. You use this field to define the setup time for every color change, or different attribute value. |
| Same attributes (field SAMVAL) |
|
Use this field to define the default setup time between matching characteristics, or attribute values of the defined attribute classification. The value can be zero. For example, a work center is used for multiple products with the same attribute classification such as paint. Cleaning the work center before replacing the same color into the spray system takes the same length of time for every color match. You use this field to define the setup time for every matching color, or matching attribute value. |
| Time unit (field TIMUOMCOD) |
|
This field displays the value Hours. This is the unit of time used in work order operations, and in which these default setup times are measured. |
Tab Exceptions
Use this section to create a table of exceptions for the defined attribute classification. You only use this section if the from/to attribute values are different from the default setup times defined in the home section.
Grid
| From attribute value (field FROATTVAL) |
|
Use this field to identify an individual characteristic of this attribute classification. For example, if your company manufactures bicycles and the attribute classification is COLOR, this field value is a color that might be sprayed on a bicycle frame. |
| Description from (field FAVDESAXX) |
|
This field identifies the individual characteristic that you have defined in this attribute classification. |
| To attribute value (field TOATTVAL) |
|
Use this field to identify an individual characteristic of this attribute classification. For example, if your company manufactures bicycles and the attribute classification is COLOR, this field value is a color that might be sprayed on a bicycle frame. |
| Description to (field TAVDESAXX) |
|
This field identifies the individual characteristic that you have defined in this attribute classification. |
| Setup time (field SETTIM) |
|
Use this field to specify the actual time it takes to prepare a work center when changing from a product with the attribute characteristic assigned in the From attribute value field (FROATTVAL) to a product with the attribute characteristic assigned in the To attribute value field (TOATTVAL). This time forms part of the work center load. It is expressed in the time unit specified in the Time unit field (TIMUOMCOD). |
| Time unit (field TIMUOMCOD) |
|
This field displays the value Hours. This is the unit of time used in work order operations, and in which these setup time exceptions are measured. |
