Factory Data Collection System

Factory Data Collection System;

FDC system is used to collect data for monitoring order progress in SFC. The following are important data collected by the FDC system.

·        Number of products (piece counts) completed at a certain machine.

·        Number of parts scrapped (or) Number of parts reworked.

·        Direct labor time spent

·        Equipment breakdown.

Purpose of data collection system;

The purpose of the data collection system in shop floor control is to provide basic data for monitoring order progress.

In computerized SFC system the data are submitted to the order progress module for analysis and generation of work order status reports and exception reports.

Types of data collection systems;

·        On-line data collection systems

·        Off-line data collection systems

Types of data collected from the shop floor;

·        Machine data,

·        Operator data,

·        Tooling data,

·        Data relating to jobs to be done,

·        Materials data,

·        Materials handling data,

·        Scheduling data,

·        Process planning data, and

·        Inspection data.

·        Data collection techniques in shop floor control?

·        Job traveler

·        Employee time sheet

·        Operation tear strips or punched cards included with shop packet

·        Centralized shop floor terminals

·        Individual work centre terminals

Computer process monitoring (Computer assisted data collection systems);

Computer process monitoring is a data collection system in which the computer is directly connected to the workstation and associated equipment for the purpose of observing the operation.

Components used to build a computer process monitoring system

·        Transducers and sensors,

·        Analog to digital converters (ADC),

·        Multiplexers,

·        Real time clocks, and

·        Other electronic devices

·        Configurations of computer assisted data collection systems

·        Or (Automated data collection system)?

·        Data logging systems

·        Data acquisition systems

·        Multilevel scanning

Types of data collection systems;

·        On-line data collection systems

·        Off-line data collection systems

Factory Data Collection System

·        On-line versus batch systems

·        Data input techniques
