Perimattic

Production Planning and Scheduling Software That Gives Your Factory Achievable, Visible Production Plans

Most production planning processes produce schedules that look achievable on paper but fail on the shop floor — because they do not account for actual machine capacity, material availability, tooling constraints, or operator availability at the time of scheduling. Perimattic builds custom production planning and scheduling platforms that take real capacity constraints into account, generate finite schedules that the shop floor can execute, and synchronise material requirements, resource allocation, and production commitments with ERP and MES systems throughout.

Overview

What Is Production Planning and Scheduling Software, and Why Does Manufacturing Throughput Depend on It?

Production planning and scheduling software generates finite production schedules by taking actual manufacturing constraints into account — machine capacity, tooling availability, operator skills, material stock levels, and maintenance windows — rather than assuming unlimited resources as ERP production order modules typically do. A production planning platform receives demand from sales orders or a master production schedule, checks available capacity and material, and generates an ordered sequence of production operations that the factory can physically execute. It connects material requirements, resource allocation, and customer delivery commitments into a single, visible, and achievable production plan.

The challenge for most manufacturing operations is that ERP production orders are generated without reference to actual shop floor capacity. When a production order is released into a factory where the required machine is already loaded, the required tooling is committed to another job, or the required material has not arrived, the plan fails. Planners spend their time manually adjusting schedules to account for constraints the planning system has ignored. Shop floor supervisors manage an order list rather than an executable sequence. Customer delivery commitments are based on system-generated dates that bear no relation to what the factory can realistically produce. The result is missed commitments, elevated work-in-progress, and a planning function that operates on instinct rather than a visible, trusted production plan.

Perimattic builds custom production planning and scheduling platforms that start from the actual constraints of the manufacturing operation — the machines, tooling, operators, and material lead times that determine what the factory can produce, and when. Every engagement begins with a thorough mapping of the constraint landscape before any scheduling engine decisions are made. We design integration architectures that connect the planning platform to ERP for order management and material data, and to MES for real-time execution feedback. We build in phases, validating the scheduling model against real production scenarios before full deployment, so that the platform planners receive is one they trust and use rather than one that generates output they must manually correct.

Unconstrained ERP Scheduling vs. Custom Planning Platform

Unconstrained ERP Scheduling
Custom Planning Platform (Perimattic)

Schedule achievability

Infinite capacity schedules that ignore machine and material constraints — plans that look correct on screen but require manual planner correction before the shop floor can use them

Schedule achievability

Finite schedules built from actual capacity and material availability — production sequences the factory can execute without manual planner correction

Material alignment

Production orders released without confirming material availability — shortages discovered at the point of production rather than during planning

Material alignment

Material requirements checked against stock and purchase orders before release — shortages flagged during scheduling so procurement can act before production is affected

Capacity visibility

No view of machine loading across work centres — planners manage capacity manually using spreadsheets and experience

Capacity visibility

Real-time capacity utilisation across all work centres — machine loading visible to planners and updated as the schedule changes

Schedule changes

Re-scheduling requires manual planner intervention for each affected order — a machine breakdown or urgent order can take hours to resolve across the plan

Schedule changes

Automated re-sequencing when constraints change — the platform recalculates the impact of a disruption and presents a revised schedule for planner approval

Shop floor integration

Schedules printed or exported to the shop floor — no feedback from production on actual progress, so the plan drifts from reality throughout the day

Shop floor integration

Live schedule visible to the shop floor via MES with real-time progress feedback — the planning platform knows what has been completed and recalculates remaining work accordingly

The operational cost of unconstrained ERP scheduling becomes visible as the gap between the plan release date and the actual factory output — in missed delivery commitments, elevated work-in-progress, and the proportion of planner time spent correcting schedules rather than managing production.

Core Services

Production Planning Software We Build

Seven production planning and scheduling capability areas covering the complete planning stack — from custom platform development and finite scheduling through material requirements, demand management, resource planning, optimisation, and MES and ERP integration.

Custom Production Planning Platform Development

Bespoke production planning and scheduling platforms built around the specific production model, constraints, and planning horizon of the manufacturing operation. Engineered to the actual constraint landscape of the factory rather than the feature set of a packaged product — so planners trust the output and the shop floor can execute the schedule.

Finite Capacity Scheduling

Constraint-aware scheduling that takes machine availability, tooling, operator skills, and maintenance windows into account when generating production sequences. The scheduling engine models the real capacity of each work centre and produces schedules that the factory can physically execute — not infinite-capacity plans that planners must manually correct before releasing to the shop floor.

Material Requirements Planning Integration

MRP calculation, material availability checking, and purchase requisition triggering connected to production schedule generation. The platform checks material stock and open purchase orders against production order requirements before confirming schedule dates — ensuring that material shortages are identified and flagged before they cause production stops rather than after.

Demand Management and Order Promising

Sales order to production order translation, available-to-promise calculation, and customer delivery commitment management. The platform calculates whether capacity and material are available to meet requested delivery dates, provides accurate promise dates when requested dates cannot be met, and tracks commitment risk as the schedule evolves.

Resource and Workforce Planning

Operator skill-based assignment, shift planning, and resource capacity management integrated with production scheduling. The platform allocates operators to production operations based on skill requirements and shift availability, models the impact of operator absence on schedule capacity, and generates resource plans that planners and shift managers can use to staff the factory appropriately.

Production Schedule Optimisation

Optimisation algorithms minimising changeovers, maximising throughput, and meeting delivery commitments under real constraints. We select and configure the optimisation approach — constraint satisfaction, genetic algorithms, OR-Tools — based on the specific constraint landscape and planning horizon of the operation, producing sequences that reduce non-productive changeover time while maintaining customer delivery priorities.

MES and ERP Integration

Bidirectional integration with MES for real-time schedule execution feedback and ERP for order management, material movements, and financial reporting. The planning platform sends production schedules to the MES and receives completion events, scrap records, and downtime notifications in return — keeping the plan aligned with shop floor reality throughout the production day.

How We Engage

Our Production Planning Platform Development Process

A structured six-stage process from free production planning discovery through deployment and ongoing schedule model optimisation.

01

Production Planning and Scheduling Discovery (Free)

We map your existing production planning processes, constraint landscape, current scheduling gaps, ERP and MES integration requirements, and pain points. This free session establishes a clear picture of current-state planning workflows and system dependencies before any platform architecture decisions are made.

02

Capacity and Constraint Mapping

We document work centres, machine capacities, tooling constraints, operator skills, shift patterns, maintenance windows, and planning horizon requirements in detail — producing the constraint model that the scheduling engine will be built around.

03

Planning Platform Architecture and Proof of Concept

We design the scheduling engine architecture and build a proof of concept against the most constrained production scenario to validate the finite scheduling approach and surface any modelling risks before full development investment begins.

04

Platform Development and MES/ERP Integration

We develop the production planning platform incrementally, building the scheduling engine, constraint model, and optimisation layer alongside MES and ERP integrations — delivering working scheduling capability at each phase.

05

Testing, Validation, and Planner Acceptance

We test the platform against real production planning scenarios including constraint conflicts, demand fluctuations, urgent order insertion, and machine downtime events. We run user acceptance testing with planning and production teams before any production go-live.

06

Deployment, Monitoring, and Ongoing Optimisation

We deploy with monitoring and alerting, support schedule model evolution as production constraints change, and retrain optimisation parameters as the production mix and capacity landscape evolve over time.

Why Perimattic

Why Manufacturing Leaders Choose Perimattic to Build Their Planning Platform

Four structural advantages that separate production planning software built for real manufacturing constraints from scheduling tools that produce plans planners cannot trust or the shop floor cannot execute.

01

Constraint Discovery Before Scheduling Engine Design

Every production planning engagement begins with a thorough mapping of the actual production constraints — machine capacities, tooling, operator skills, shift patterns, and material lead times — before designing the scheduling model. A finite scheduler is only as good as the constraints it models; a scheduling engine built on an incomplete constraint model produces plans that planners will override rather than use.

02

MES Integration That Feeds Back Real Execution Data

Schedule accuracy depends on real-time progress feedback from the shop floor. We build the MES integration that closes the loop between the production plan and shop floor reality — sending scheduled operations to the MES and receiving completion events, scrap, and downtime notifications in return. Without this feedback loop, the planning platform operates on stale data and produces schedules that diverge from the factory's actual state.

03

Material Availability Integrated Into Schedule Generation From Day One

Production schedules that do not check material availability produce theoretical plans, not executable ones. We integrate material availability checking and MRP logic into the schedule generation process from the start — so that the platform only confirms schedule dates for orders where material will be available, and flags shortages proactively rather than allowing them to surface as production stops.

04

Strategy and Planning Platform Build in One Engagement

The team that maps your production constraints and designs the scheduling architecture also builds, tests, and deploys it. There is no handoff between a consulting team and a delivery team, no loss of constraint modelling context between discovery and implementation. You work with the same engineering team from the initial constraint mapping through production deployment and ongoing schedule model optimisation.

“A production schedule that does not account for actual machine capacity, tooling availability, and material stock is a wish list. The value of production planning software is the gap it closes between what is demanded and what the factory can realistically produce — and that gap is only visible when constraints are modelled accurately.”

FAQ

Production Planning Software Development: Frequently Asked Questions

What is custom production planning and scheduling software?

Custom production planning and scheduling software is a purpose-built platform that generates finite production schedules by taking actual manufacturing constraints into account — machine capacity, tooling availability, operator skills, material stock, and maintenance windows — rather than assuming unlimited resources. Unlike ERP production order modules that produce infinite-capacity schedules, a custom planning platform is engineered to the specific production model, constraint landscape, and planning horizon of the manufacturing operation. It connects material requirements, resource allocation, and customer delivery commitments into a single, executable production plan that the shop floor can actually follow.

What is the difference between finite and infinite capacity scheduling?

Infinite capacity scheduling — the approach used by most ERP systems — generates production orders based purely on demand and lead times, without checking whether the required machine capacity, tooling, or operator availability actually exists at the time the work is scheduled. The result is plans that look achievable on paper but create overload at constrained work centres and missed deliveries on the shop floor. Finite capacity scheduling takes actual capacity constraints into account when generating the production sequence: it models machine availability, tooling, shift patterns, and maintenance windows, and only schedules work that the factory can physically execute in the available time. The difference between the two approaches shows up as the gap between what the plan says and what the factory can actually deliver.

Why build custom production planning software rather than using ERP scheduling modules?

ERP scheduling modules are designed for broad applicability across many industries and typically operate on simplified capacity models — infinite capacity or very coarse finite capacity with limited constraint modelling. For manufacturing operations with complex constraint landscapes — high-mix production, sequence-dependent changeovers, shared tooling, operator skill requirements, or campaign planning — ERP scheduling modules consistently produce plans that planners override manually. A custom production planning platform is built around the specific constraints that govern your factory, models those constraints accurately, and produces schedules that planners trust and the shop floor can execute. The investment in a custom platform pays back through reduced schedule failures, lower work-in-progress, and improved delivery performance.

How does production planning software integrate with MES and shop floor systems?

Production planning software integrates with MES through bidirectional interfaces that send scheduled production orders to the shop floor and receive real-time execution feedback in return. The planning platform sends the schedule — job sequences, operation start times, machine and operator assignments — to the MES, which translates those instructions into shop floor work orders and operator instructions. As production progresses, the MES sends actual completion events, scrap records, and downtime notifications back to the planning platform, which uses this feedback to update the current schedule and recalculate remaining work. We build both sides of this integration: the schedule publication interface from planning to MES, and the execution feedback interface from MES back to planning.

How does production planning software handle material availability and MRP?

Production planning software integrates material availability checking into the schedule generation process so that only production orders with confirmed material availability — or a clear material arrival date — are released to the shop floor. The platform checks current stock levels, open purchase orders, and in-transit material against each production order's material requirements before confirming a schedule date. Where material will not be available by the planned start date, the system flags the shortage, calculates the earliest possible start based on expected material arrival, and adjusts the schedule accordingly. For operations where material procurement lead times are a primary planning constraint, the platform can trigger purchase requisitions automatically when production orders are generated.

Can production planning software manage multiple product types and mixed-model production?

Yes. Mixed-model production planning is one of the core use cases for custom scheduling platforms. The scheduling engine models the specific constraints for each product family — changeover sequences, tooling requirements, batch sizes, operator skills — and applies these constraints when generating the production sequence. For high-mix low-volume operations, the platform optimises job sequencing to minimise changeover time while meeting delivery commitments. For mixed-model assembly lines, it applies takt time and line balancing logic to distribute work across stations. The platform is configured to the specific production model of the operation rather than applying a generic scheduling approach across all product types.

How does a production scheduling engine optimise sequence and changeovers?

Production scheduling engines optimise sequence by applying constraint satisfaction and mathematical optimisation algorithms — including OR-Tools, genetic algorithms, and simulated annealing — to find production sequences that minimise changeover time, maximise throughput, and meet delivery commitments simultaneously. The engine uses a changeover matrix that defines the setup time required when switching from one product family to another at each work centre, and factors this matrix into sequence decisions. The result is a production sequence that reduces non-productive changeover time while maintaining the delivery priority order required by customer commitments. We select and configure the optimisation approach based on the specific constraint landscape and planning horizon of the operation.

Can a production planning platform integrate with customer orders and delivery commitments?

Yes. Customer order integration is a core component of production planning platforms. The platform receives sales orders from ERP or order management systems, translates them into production orders with required completion dates, and calculates available-to-promise dates based on current capacity loading and material availability. When a new customer order is entered, the platform checks whether capacity and material are available to meet the requested delivery date, and provides an accurate promise date if the requested date cannot be met. As production progresses and the schedule changes, the platform recalculates delivery commitments and flags orders at risk of missing their promised dates before the miss occurs.

How does production planning software handle urgent orders and schedule disruptions?

Production planning software handles urgent orders and disruptions through automated re-sequencing that recalculates the impact of a change on the full schedule and presents planners with the revised plan and its consequences before any changes are applied. When an urgent order is inserted or a machine breaks down, the platform models the impact — which orders are displaced, which commitments are now at risk — and generates a revised schedule that accommodates the disruption. Planners can review and approve the revised schedule or manually override the system's recommendation. For routine disruptions, the platform can apply predefined rules automatically — for example, always protecting the highest-priority customer orders — without requiring planner intervention for each affected order.

How does the production planning software development process work?

We follow a structured six-stage process: a free discovery session to map production planning processes, constraint landscape, current scheduling gaps, and ERP and MES integration requirements; a capacity and constraint mapping phase that documents work centres, machine capacities, tooling, operator skills, and planning horizon requirements in detail; a planning platform architecture and proof-of-concept phase that designs the scheduling engine and validates the finite scheduling approach against the most constrained production scenario; platform development and MES/ERP integration; testing, validation, and planner acceptance against real production planning scenarios including constraint conflicts and demand fluctuations; and deployment with monitoring, ongoing optimisation support, and schedule model evolution as production constraints change.
