Schedlyzer
(Scheduling Software for High-Variety Custom Production)
Please visit our updated page,
http://optisol.biz/Schedlyzer/
Schedlyzer is a versatile, powerful and affordable
software tool for scheduling order-driven, high-mix, low- volume
production. Based on rigorous, finite capacity scheduling logic, Schedlyzer
generates an optimal production schedule without resource overloading
almost instantaneously. As shown on
our web page, Lean Production,
optimal job release times determined by
Schedlyzer ensure minimal WIP and short job lead times. The software helps extract
the best shop performance from the existing limited resources first and
helps find and implement the most cost-effective changes to the system one
by one for improving plant production performance.
Schedlyzer
supports the objectives of maximizing on-time delivery, throughput and
overall productivity of resources and minimizing WIP, production lead
times and firefighting by optimally scheduling operations with the help
of rigorous logic.
It also identifies bottlenecks in the system and provides
intelligent decision support for managing production efficiently
and for negotiating with customers in quoting lead times for
new orders. Development of Schedlyzer is based on the premise
that control and management of job shop production will be more efficient
with the help of:
- Operations
scheduling
- Prediction of workflow, bottleneck occurrences and order completion times
- What-if analysis of workflow
- Proactive capacity planning
- Intelligent decision support.
Some Functions and Features of Schedlyzer:
1. Display of
Current Status of Jobs:
Schedlyzer shows all
operations which are either ongoing or ready for processing at
the time of scheduling. All such operations may not be scheduled
at that time due to limited resources. Schedlyzer shows
scheduled ones among those operations in a different color. This
information can also be seen for each work center separately.
2. Generation of Job Schedules and Dispatch Lists for Resources:
For day-to-day production control, supervisors and workers need
a display of current status and projected progress of jobs and a
dispatch list (operation sequence) for each resource. Schedlyzer
generates both of them as part of the scheduling exercise. It
can revise them instantaneously whenever required if fresh job
status information is available to it. Such revision may be
necessary for dealing with unexpected changes like machine
breakdown, worker absenteeism and rework.
3. Fixing
Rational Lead Times for New Orders:
For many job shops, the
problem of managing order-driven, high-variety production starts
with determination of lead times for new orders. Those shops may
have stringent due dates imposed by some powerful customers and
a need for fixing rational due dates for new orders based on the
existing workload and resource capacities.
In many job
shops where bottlenecks keep moving over time due to changing
product mix, it is truly a challenge to fix an appropriate due
date (or lead time) for each new order. Shorter lead time
quotation can cause anxiety and firefighting while longer
quotation can disappoint customers. Balancing both risks,
Schedlyzer will find a right lead time for each new order based
on the existing workload and resource capabilities and
capacities (avoiding guesswork and standard, time-invariant
quotation of lead times).
4. Determining Optimal Start Times
for Jobs:
One of the most difficult decisions to be made in
high-variety, order-driven production is to find a right start
time for each job based on the existing workload and resource
capacities. Early job start times can result in higher WIP and
longer lead times whereas late start may result in the reduction
of shop productivity, resource utilization and on-time delivery.
Schedlyzer finds right job start times (as shown on the page,
Lean Production) balancing both risks by taking into account
process and resource requirements of jobs, due dates and
resource capacities.
5. Handling Vendor Operations and
Material Available Times:
Many people face
some difficulty to include vendor operations in the schedule
because progress of those operations cannot be monitored like
that of internal operations. Schedlyzer efficiently incorporates
vendor operations and material available times into
production schedule.
6. Handling Multi-Resource Requirements of Operations and General Precedence
Relations among Operations:
In some cases, an operation may
simultaneously require two or more resources like machine plus
worker and wait until all the required resources are available
at the same time. Schedlyzer can easily schedule such operations
with a feasible assignment of the required resources. Many scheduling tools are unable to handle
multi-resource requirements of operations. Schedlyzer accepts
general precedence relations among operations of any job and
therefore, it can easily schedule project-oriented production
where each order can be viewed a project of several tasks.
7. Optimal
Utilization of Multi-Functional Machines and Multi-Skilled
Workers:
Small and mid-sized job shops which
need to perform a vareity of operations as required by customer
orders usually employ multi-skilled workers for achieving
the maximum productivity of workers. Similarly, they also use
multi-functional machines for achieving the maximum productivity of
machines. Resources may have different working hours (shifts /
calendars) and calendar exceptions like machine breakdowns and
worker absenteeism.
Schedlyzer generates a high quality schedule by optimally
assigning multi-skilled workers and multi-functional machines to
operations. This is possible when resource requirement of
operations is specified in terms of skill and machine function
rather than specific resource names. Such schedules improve shop
throughput, on-time delivery, WIP and order lead times.
8. Prediction of Workflow, Bottlenecks and Job Completion Times:
A reliable prediction of workflow, bottleneck
formations and job completion times can give great confidence to
people who manage high-variety production. Control and
management by reliable workflow prediction is efficient for
high-variety production. Schedlyzer offers such prediction in
the form of schedule by taking into account both resource
availability and natural variation in the system.
9. Enabling What-If Analysis of Schedules:
Production people
develop a schedule mainly for production control on shop floor.
However, if a simple and powerful solution is available for
quickly generating a meaningful schedule with minimal effort,
then it can be used for fast and extensive what-if analysis of
schedules. Proper what-if analysis greatly helps in evaluating
and comparing various alternative decisions for efficient
management of high-variety production. Quick and reliable
what-if analysis will be very useful in production meetings. As indicated in its name,
Schedlyzer is developed with special emphasis on what-if
analysis for high-variety production.
10. Facilitating
Proactive Capacity Planning:
This is very
relevant to a high-variety production system which does not have
steady demand for many types of products. The varying product
mix keeps changing the amount of workload for some resources and
consequently bottlenecks may keep changing over time. This
necessitates dynamic capacity adjustments at work stations.
Schedlyzer enables planners to foresee the need for such
adjustments and make optimal decisions.
11. Enabling
Study and Analysis of Dynamic Nature of High-Variety Production:
Schedlyzer can also be used for studying and
analyzing the dynamic nature of high-variety, order-driven
production systems to form mid-term and long-term company
strategies.
Schedule Output:
Schedule output consists of job schedule summary, resource utilization percentages (for any selected time
period), projected daily resource utilization levels, detailed job schedules and detailed resource schedules.
Schedlyzer
provides powerful graphic features and drag-and-drop options.
Gantt charts graphically display, with zooming
option, summarized job schedules and detailed schedules of jobs and resources. Drag-and-drop operation is available on Gantt chart to
manually change a schedule generated by Schedlyzer without violating any constraints. Schedlyzer however reduces the need for drag-and-drop
operations by scheduling all the workload efficiently and automatically with the help of advanced algorithms. Users can save schedule
output in many formats including Excel.
