Production System Design


Manufacturing - (Latin - produce by hand)
Production - Broader word - Something that
is produced by physical or intellectual labor



Products - Goods - Services - Poems
Two words are practically synonyms; making
something someone wants
We are dealing with organizations that
produce a good or service

Production System Design



System: Collection of components that
accomplish production
Design: Provide the detailed
specification for the components
The IE designs and operates the
system of production

Hierarchical issues make
integrated design difficult



A particular design problem falls within a
hierarchy of designs
The design activity must recognize
impacts on other levels
The design affects operations
5

What this course will do:





Provide an understanding of problems and
issues in production system design
Build models to describe the components of
production processes
Build models to describe the system of
production
Use operations research tools to analyze
models and make decisions
Identify, quantify and alleviate waste in the
manufacturing process
