Products Life Cycle

• Introduction
  • Critical design and development phases
  • Frequent changes in product and process design
  • Short production runs
  • High production costs
  • Attention to quality
• Growth
  • Forecasting needed
  • Competitive product improvements
  • Increase of capacity
  • Enhanced distribution
• Maturity
  • Standardization of products (no changes)
  • High capacity, long production runs
  • Cost cutting
  • Increasing stability of processes
• Decline
  • Overcapacity ➔ Retool
  • Try to eliminate items not returning good margins

Production

It is the sum of the processes and methods used to transform tangible inputs (raw materials, subassemblies,...) and intangible inputs (information, knowledge,...) into goods or services/ output that are suitable for use or have exchange value.

Production System

A production system is the combination of the production processes and all the management subsystems contributing to make the transformation (production process).

PRODUCTION PROCESS

Production process is the transformation of starting resources (input) into finished products or goods (output) taking place in a production system.

Technologically speaking, it is the application of physical and chemical processes to alter geometry, properties or appearance of a given starting material to create products.

Economically speaking, it is the transformation of materials into items of greater values by means of one or more operations.

It can be:

• DISCRETE PART PRODUCTION SYSTEM (each part is distinct)
• CONTINUOUS GOOD PRODUCTION (never stops for fluids, powders)

• DESIGN
• INDUSTRIALIZATION
• PRODUCTION

• Engineering Drawings
• Bill of materials BOM
• Route Sheet (Technological cycle)
• Processing and assembly drawings

BOM

Hierarchical and structural depiction of all the objects (sub-assemblies, components, raw materials) composing a product (parents items / children items).

ASSEMBLY DRAWING

They show exploded views of products and how to assemble them.

ROUTE SHEET

It contains the list of operations, with resources and time required.

WORK ORDER

It contains instructions to produce a given quantity (where, when, how much).

Production processes are multi-stage processes. It means that a sequence of operations are required to realize the process that allows to obtain a product from a raw material. The set of data that describes the sequence of su
