What does it take to make?
What do we have?

QUESTİONS OF A PLANNİNG SYSTEM
Priority:
What is needed?When?How much?
(Market)
Capacity:
Capability to produce what is needed
and when? 4
CAPACİTY
Capacity is the capability of
manufacturing in a period of time.
Capacity is up to resources of company as
machinery, labor, financial resources and
availability of materials form suppliers.

CAPACİTY MANAGEMENT
At each level of the planning and control
system, reconcilation with resources must be
made.
Inadeqaute resources=missed production
schedules
Resources significantly exceed planned
production=idle resources and extra cost.12

SALES AND OPERATİONS PLANNİNG
It can be used to update the strategic plan.
It provides a tool to manage change.
It enforces functional plans to be realistic and
coordinated.
It represents a plan to achieve company objectives
It provides management visibility of production,
inventory and backlogs. 14
BASİC PRODUCTİON PLAN STRATEGİES
Chase:Vary production rates to meet changes in
demand Often used when inventory cannot be used or when resources
are flexible and inexpensive to change
Level:Establish average demand level and set production
rate to that level
Often used when resources difficult or very expensive to
change
Hybrid: A combination of two strategies.

When to order
When to schedule delivery
Keep priorities current

BOM
40
BOM The BOM shows all parts to make one of the
item
Each part has one, and only one, part number
A part is defined by form, fit, and function – any
change requires a new part number
41
BOM
Defines the product
Provides method for design change control
Planning: What is needed and when?
Order Entry,order configuration and pricing
Production:Parts needed to assemble
Costing: Material cost of goods sold
