What is mpc

What is MPC?

  • MPC: Manufacturing Planning and Control

  • MPC system provides information to efficiently manage

    • the flow of materials

    • the utilization of people and equipment

    • the coordination of internal activities with those of suppliers

    • communication with customers about market requirements

  • MPC is costly to set up and operate

  • An effective MPC system creates competitive advantage by

    • decreasing costs

    • increasing responsiveness


Typical activities that mpc support

Typical Activities that MPC Support

  • Long term

    • overall capacity planning (internal and with suppliers)

  • Intermediate term

    • providing the exact material and production capacity to match supply and demand

      • maintaining inventories

      • determining the employment levels

    • communicating with customers and suppliers

  • Short term

    • detailed scheduling of resources and tracking their usage

    • responding to internal and external problems/changes

    • calculation and reporting of performance indicators

      • utilization rates, delivery performance etc.


The mpc framework

The MPC Framework

Sales and operations planning (Aggregate planning)

Resource planning

Demand management

Front End

Master production scheduling (MPS)

Detailed capacity planning

Detailed material planning (using MRP)

Engine

Material and capacity plans

Shop floor systems

Supplier systems

Back End


Mpc framework front end

MPC Framework: Front End

  • The Front End: The set of activities for overall direction setting for manufacturing planning and control

    • demand management

      • forecasting

    • sales and operations planning (also called “aggregate planning”)

      • to balance the marketing plans with available production resources

    • master production schedule (MPS): disaggregated version of the sales and operations plan (aggregate production plan)

    • resource planning


Mpc framework engine and back end

MPC Framework: Engine and Back End

  • The Engine: Includes activities on detailed material and capacity planning

    • material requirements planning (MRP)

      • determines the period-by-period plans for all components required

    • detailed capacity planning

  • The Back-End: Includes execution systems

    • shop floor systems

    • supplier systems


Mpc classification schema

Project

Number of subparts (complexity of product)

MRP

Just-in-time

Repetitive

Flow

Seconds

Minutes

Days

Weeks

Months

Time between successive units (repetitive nature of production)

MPC Classification Schema

Different MPC Approaches


Mpc needs to respond to changes in environment

MPC needs to Respond to Changes in Environment


Key developments to influence mpc

Key Developments to Influence MPC

  • Internationalization

  • The role of the customer

  • Increasing use of information technology

    • classical MPC: individual factory level

    • enterprise resource planning (ERP) systems allow coordinated decision making across different locations and functions

      • most MPC systems now are imbedded in an ERP system
