What to measure at each station of a line, and how.

Research proposal

  • Petri nets
  • Machine data
lights up: measure

The case

Each station has its own control.

The case study: five stations on a conveyorDistribution, inspection, transport, assembly and output on a conveyor belt, each station with its own control and light. A good part gets a pin, a spring and a cap and reaches the output. A part out of specification goes to the reject bin.distributioninspectiontransportassemblyoutput The case study: five stations on a conveyorDistribution, inspection, transport, assembly and output on a conveyor belt, each station with its own control and light.

The indicators

39 indicators in four groups.

The 39 indicators, in four groupsA ring in four sectors: environmental (10), economic (10), social (9) and technological (10). The technological sector stands out and leads to three indicators: inspection for maintenance, cycles and wear, safety against stoppages.39inspection for maintenancecycles and wearsafety against stoppages The 39 indicators, in four groupsA ring in four sectors: environmental (10), economic (10), social (9) and technological (10).

  • inspection for maintenance
  • cycles and wear
  • safety against stoppages
  • environmental 10
  • economic 10
  • social 9
  • technological 10

The technological group already includes machine data.

Still open

  • It is the project proposal: it defines what to measure and how to calculate it.
  • It contains no measurements.
  • The idea came back in Sustainability.data.

Tools

  • sustainability indicators
  • Petri nets · model of the studied system
  • ANSI/ISA-95
  • theory, tools and applications cycle
