Schedule Subset of Shop Orders

Explanation

This activity is used to finite schedule shop order operations manually that belong to the specified subsets.

To perform this activity on the Finite Schedule Shop Order(s) page, select the site. After selecting the site, specify the subsets as per the scheduling requirement.

What are Subsets?

A subset refers to a group of resources within a manufacturing site that can operate independently from other resource groups. For example, in a high-tech manufacturing organization, one subset of resources might be dedicated to handling electrical or electronic shop order operations, while another subset focuses on mechanical operations. These subsets typically function without interdependencies and often operate at different physical locations or sites. However, they usually share a common inventory supply source or warehouse.

How Subsets are selected?

On the Finite Schedule Shop Order(s) page, after selecting the site, Users can specify the subsets as per the scheduling requirement. Users can select based on Shop Order Attributes as well as the Order Structures based attributes.

Ex.1 Random Finite Work Center as Subset

Subset Defined by User Selected Orders Secondary Additions to Selection
Work Center A Shop Order 1 Shop Order 2 <==Selected Since it is scheduling on Work Center B & C Finite capacity work centers which is used in subset selection given by User
Based on subset, MSO identified Resources to re-schedule Work Centers A,B,C,D,E,F
Labor Classes 2

Note: Shop Order 3 is not considered for rescheduling because it pertains only to the user-selected subset, due to its association with Work Center D. Since Work Center D is defined as an infinite resource, its load does not affect scheduling constraints. Therefore, in this situation operations assigned to infinite work centers like Work Center D can be excluded from the scheduling process.

Ex.2 Random Infinite Work Center as Subset

Subset Defined by User Selected Orders Secondary Additions to Selection
Work Center D Shop Order 1 None
Shop Order 2
Shop Order 3
MSO identified Subset of Resources to re-schedule Work Centers A,B,C,D,E,F,G,H
Labor Classes 1,2

Note: Shop Order 4 is not considered for rescheduling because it pertains only to the user-selected subset, due to its association with Work Center H. Since Work Center H is defined as an infinite resource, its load does not affect scheduling constraints. Therefore, in this situation operations assigned to infinite work centers like Work Center H can be excluded from the scheduling process.

Ex.3 Need date within next week as Subset

Subset Defined by User Selected Orders Secondary Additions to Selection
Need Date within Next Week Shop Order 2 Shop Order 1
Shop Order 4
MSO identified Subset of Resources to re-schedule Work Centers A,B,C,D,E,F,H
Labor Classes 2

Note: Work Center A and F are included in the rescheduling request because they are required to reschedule Shop Order 1. However if Work center F had more operations they can be exempted from the scheduling request since it is Infinite Capacity work center

Ex.4 Order structure DOP ID:1 as Subset

Subset Defined by User Selected Orders Secondary Additions to Selection
Need Date within Next Week Shop Order 2 Shop Order 1
Shop Order 4
MSO identified Subset of Resources to re-schedule Work Centers A,B,C,D,E,F,H
Labor Classes 2

Note: Work Center A and F are included in the rescheduling request because they are required to reschedule Shop Order 1. However if Work center F had more operations they can be exempted from the scheduling request since it is Infinite Capacity work center.

 Important:

This functionality is specifically designed to schedule pure resource subsets efficiently, minimizing the load on the MSO scheduling service by avoiding unnecessary site-wide data.

 If order structures (such as DOPs, Projects, etc.) span across multiple resource subsets, they cannot be considered as true subsets. Scheduling such structures may lead to inaccurate results and potential resource overloads.

Likewise, scheduling order structures individually can also cause overload situations. To ensure accurate and conflict-free scheduling, always select all order structures that share the same resource subsets and perform finite scheduling with MSO accordingly.
