What Is Concurrent Planning and Scheduling?
Concurrent planning and scheduling means planning demand, parts, capacity, labor, and job sequence together. It helps teams build schedules that reflect real constraints. As a result, planners can set better dates, react faster, and reduce chaos.

Why Accurate Production Schedules Break Down
Production schedules often fail when the plan and schedule sit in separate steps. The plan may show demand and due dates. However, the schedule may miss parts, labor, run rates, changeovers, or machine load.
Therefore, planners may promise dates the plant cannot meet. When demand shifts, a machine stops, or parts arrive late, teams may see the risk too late.
This method fixes the gap by linking the plan to the schedule. It shows what can run, when it can run, and how each change affects customer dates.
What Concurrent Planning and Scheduling Helps Manufacturers Do
This approach gives planners a clearer view of plant work. It also helps teams make faster choices because demand, supply, capacity, and rules stay connected.
Commit Quickly
Planners can commit faster when they know if capacity, labor, and parts can support the order. Instead of waiting for many team checks, they can review limits in one model.
Promise Delivery Dates Realistically
Accurate promise dates depend on more than demand. They also depend on parts, run rates, changeovers, labor, and bottleneck resources. Therefore, planners should test these limits before they confirm a date.
React to Disruptions Faster
Plant disruptions happen often. For example, parts may arrive late, a machine may stop, or a rush order may appear. With a linked plan and schedule, planners can see the impact sooner.
Deliver On Time More Reliably
On-time delivery improves when schedules reflect real plant limits. As a result, planners can cut expediting, avoid extra schedule changes, and give service teams better dates.
How APS Supports Concurrent Planning and Scheduling
PlanetTogether APS connects plans with finite-capacity schedules. It checks limits, sequence rules, priorities, parts, and capacity before teams release work.
Factory Digital Twin
A factory digital twin is a model of the plant. It shows resources, rates, yields, product mix, changeovers, queues, and limits.
The model reflects how the plant runs. Because of that, planners can trust future work times. Then they can see whether the schedule can support customer dates.
Agile Re-Scheduling
Agile re-scheduling helps planners respond when conditions change. If a disruption hits the plant, APS can help planners make a new schedule in minutes.
As a result, teams can compare options before delays grow. They can also see which orders, resources, and dates will change.
Longer Planning Horizon
A longer planning horizon helps teams look weeks or months ahead. This helps with buying, capacity load, staffing, and customer dates.
When planners see future load earlier, they can act before a bottleneck creates late orders. They can also align buying and work before shortages appear.
Better Communication and Visibility
This shared schedule helps teams work from the same plan. Production, buying, sales, and customer service can see changes sooner.
Therefore, teams can give customers clearer answers. They can also plan around current capacity, ship dates, and shop-floor updates.
Decision Framework: When Do You Need Concurrent Planning and Scheduling?
Use this method when dates depend on demand, parts, capacity, labor, and rules that change often.
Step 1: Check Whether Plans and Schedules Are Disconnected
First, look for gaps between the plan and the shop-floor schedule. If the plan misses current parts, capacity, or labor, dates may not be reliable.
Step 2: Identify the Constraint Behind Late Orders
Next, find the limit that causes the most trouble. It may be a bottleneck, missing part, long changeover, labor gap, or loaded work center.
Step 3: Test the Schedule Before Releasing It
Then test the plan against real capacity and sequence rules. This step helps planners see if the schedule can run before work reaches the floor.
Step 4: Share the Updated Schedule Across Teams
Finally, share the updated schedule with planning, production, procurement, sales, and customer service. Shared visibility helps teams respond faster and reduce conflict.
Advanced Planning and Scheduling Software for Concurrent Planning
APS helps plants build feasible schedules when demand, product mix, due dates, and inventory targets keep changing.
APS can connect with ERP/MRP systems to improve speed and schedule accuracy. ERP and MRP systems manage orders, stock, and transactions. However, APS adds finite capacity, sequence rules, constraint views, and what-if planning.
With APS, planners can:
- Build schedules that balance output and delivery.
- Increase flow on bottleneck resources.
- Match supply with demand to reduce inventory risk.
- Show teams where capacity is tight.
- Support what-if planning choices.
Video: Compare What-If Scenarios for Capacity Planning in APS
This method helps teams respond faster when demand, parts, labor, or capacity changes. However, planners still need a way to compare options before they commit to a new schedule.
In this video, see how PlanetTogether APS supports what-if scenario planning, capacity checks, and schedule comparison. The video shows how planners can find bottlenecks, test changes, and see risk before it reaches customers or the shop floor.
Build Production Schedules That Can Adjust Fast
This method helps teams connect demand, capacity, parts, and sequence rules. However, ERP and MRP tools often lack the flexibility to compare options when priorities shift.
The white paper WHY ERP ALONE IS Not the Answer explains how APS closes that gap. As a result, planners can test options, protect bottleneck resources, and improve customer dates.
In this white paper, you will learn how to:
- First, identify where ERP limits capacity and schedule optimization.
- Next, compare what-if scenarios before changing the live schedule.
- Then, connect ERP data to finite capacity, materials, and priorities.
- Also, improve visibility across planning, production, and procurement teams.
- Finally, reduce late orders, schedule disruption, and reactive expediting.
Concurrent Planning and Scheduling FAQs
What is concurrent planning and scheduling?
Concurrent planning and scheduling means planning demand, parts, capacity, labor, and sequence rules at the same time. It helps teams build schedules that reflect real plant limits.
Why do production schedules become inaccurate?
Schedules become wrong when plans miss parts, resource capacity, run rates, labor, sequence rules, or shop-floor changes.
How does APS support concurrent planning and scheduling?
APS supports this work by linking demand, parts, capacity, constraints, and priorities in one schedule model.
What is a factory digital twin in APS?
A factory digital twin is a planning model of the plant. It shows resources, rates, yields, changeovers, queues, and limits so planners can predict schedule results.
When should manufacturers use what-if scenarios?
Plants should use what-if scenarios when demand, parts, labor, machines, or priorities change. This lets planners compare schedule options before they commit.
