Shopfloor planning and inventory accounting Flashcards
Order release control, aspects to consider?
Available capacity and material requirements
Order release control, which different methods are there?
Order release from planned start times
Regulated order release
input/output control
Order release from planned start times characteristics?
Simple to apply, requires little resources
Start and due time epresent actual demand points =>basis for prioritising in the workshop
Capacity not considered=uneven workload=varying throughput times
Order release from planned start times environments to be used in?
Smooth workload
stable demand
large capacity compared to production volumes or high volume flexibility
Short throughput times and small order quantities
Regulated order release characteristics?
More complex and timeconsuming, requires advanced system support
Results i smoother workload, stable throughput times and fewer queuing problems
important to keep capacity requirements updated
Regulated order release environments to be used in?
Uneven capacity requirements
long throughput times
simple bill of materials and few operations
Input/output control characteristics?§
Simpler than regulated order release
still provides a smoothening of the workload and throughput times.
Start and due times represents actual demand points=>work as a basis for prioritizing in the workshop
IO control environments?
Manufacturing cells and lineprocesses or workshops with short throughput times
supervisor managed control characteristics?
Simple to use and has a positive effecct on the motivation of the workshops personnel
often focus on factors like setup time & throughput
less focus on material requirements
Supervisor managed control environments?
Small workshops which are easy to overview
Priority rules?
Fifo Shortest operation time Highest number of operations remaining first Largest order value first shceduling based priority rules
Priority control by priority rules characteristics?
easy to use
Priority control by priority rules environments?
Manufacturing cells and line processes
Short throughput times and few operations
Job shops
explain Priotity control by dispatch list?
CArried out centrally and communicated out
Could be based on prioority rules or more advanced methods.
Purpose of labour reporting and final reporting?
Follow up on released orders, handling potential deviations from plan.
Updating resource avaliability
Supplying information on real resource consumption, to match what was planned
