Card Based Production
Planning &Control (PPC)
System
Presented by [Ibrahim Mohammed]
Problem Statement
Q: How can we quote realistic delivery times
for Customer Order?
Ans:
• A system to keep stock and estimate
current workload and shop through-put
• A system to sequence product
transformation
• A system to monitor and control product
transformation

How To Choose?
Workload Control (WLC) Concept
• “Based on creating predictable and short
through-put times for each critical work
station”
• “predictable throughput times are important
for a good timing of order releases, for
quoting realistic delivery times, and for good
timing of capacity adjustments.”
SYSTEM COMPONENTS
1. Loop of Cards between the Shop Floor and
the Planning Office
2. Card Display Boards
3. Order Guiding Form
4. Support Staff
How it Works (Phases)

Fundamentals (Axioms)
Pillar 1: WBS
• Customer orders (products) can be broken down into sub-components
that can be routed independently, and produced as a set of basic
operations
Pillar 2: Routing/Operations Sequence
• Each subcomponent can be designed as a sequence of simple,
repetitive operations
Pillar 3: Shop Design/Structure
• The shop floor is designed to integrate human labor and machine
• Shop is divided into work centers i.e. where and when an operation
must be performed
• Shop operations are categorized by work centers
• Job dispatching rules/Job processing rules are established
Pillar 4: Training
• Training in skills and teamwork

Sequence
Cutting Room → Carving → Modeling (Application of Clay) →
Modeling (Detailing of Clay) → Metal Fabrication (Steel Framework)
→ Mold Making → GRP (Casting) → GRP (Tooling/Stamping) →
Metal Fabrication (Base Plate) → Surface preparation → Renderring
JOB ROUTING
Each Job Route = 1 Job Card → 1 Job Stage
Each Job Card = Complete List of Operation at a Job Stage

model, then degrease the mold by washing with soap and
pressurised water

What the Card System Does
• Reduces uncertainty in the control decision
by using feedback loops that update the
current situation on the shop floor in real
time
• Coordinate the flow of products through the
system
• Coordinate the flow of products in
accordance with the availability of
transforming resources
• Reduce waiting waste i.e. free up capacity
What the card System Does Not
Do
• Does not ensure quality- ensuring quality is the job of Total Quality
Mgt. (TQM) or Six Sigma
• Does not improve efficiency of material transformation
process- this is the job of design and engineering
• Does not improve efficiency of an operation itself- this is the job
of motion studies, improved job design, or improved product design
• Does not make unreliable machines reliable- this is the job of
Total Productive Maintenance (TPM)
• Does not reduce transportation waste
• Does not solve the problem of multiple points of control
• Does not solve the problem of “Jaldi Jaldi”
• Does not solve the problem of cashflow/material approval
Scaling Up
• Integration of QC Function
• Integration of Sales/Marketing Function
• Integration of Materials Inventory/Store
• Automation
