Chapter 3 Collecting Performance Data


Let us assume that the machines and the activity areas of the Sample

Enterprise that you created in "Configuring the Plant Model (page
21)" can be in one of the following machine states at any particular
time:

State

Description

Running

The machine is producing output. This state represents the ideal
state for this machine because the machine is available and

running.

Setup

The machine is being changed over for a new production run. This
state represents a minor problem. In this state, the machine is
available, but not running.

Test

The machine is in the test mode. This state represents a minor
problem. In this state, the machine is neither available nor running.

Blocked

The machine is blocked because of a problem at a downstream
machine. This state represents a major problem, but not a severe

problem. In this state, the machine is available, but not running.

Starved

The machine is starved for parts from an upstream machine. This
state represents a major problem, but not a severe problem. In this

state, the machine is available, but not running.

Linefault

The machine is simultaneously blocked because of a problem at a
downstream machine and starved for parts from an upstream

machine. This state represents a severe problem. In this state, the
machine is available, but not running.

Down

The machine is unavailable for production for some reason other

than the linefault, blocked, or starved state. This state represents a
major problem, but not a severe problem. In this state, the machine

is available, but not running.

For the sample workcell, the states are determined by collecting
values from the following data points:
