Trustworthiness Model Representation
There may be additional options to choose from depending on the situation . In this section , we show how the Trust Score and the Trust System influence the business decisions , and also the business outcomes .
Workstation Setup
Use Case 1 : Trustworthiness in a Smart , Connected Factory
REMOTE FACTORY MANAGEMENT
A senior team remotely manages the manufacturing of elevator parts in an overseas factory . The team is also responsible for managing several other geographically distributed factories . Cameras and sensors are used to collect data for the following purposes :
A . Identify workers at a specific workstation
B . Observe the manufacturing process at each workstation C . Measure the production efficiency D . Manage the safety and security of the factory floor
COLLECTION OF DATA
The goals A through D above are achieved by analyzing the camera video stream with the sensor data . The cameras capturing the workstation video feed have to be available at all times as do the sensors and the network that they are connected to . Unreliable data ( whether video or sensor ) impedes efficient remote monitoring . Inconsistent data makes it impossible for the management to monitor the product quality or to make continuous improvements to achieve their business goals .
Figure 7 : Trust computation involves each component of the workstation
Figure 7 shows an example of a workstation in this elevator parts factory . Cameras ( 5 or 6 ) mounted at each workstation capture a continuous video stream of the set of tasks related to that workstation . A worker badges in and out at the start and end of their shift at the workstation . Sensors attached to drill bits and cutting machines send data that is used to measure different aspects of the production process and the state of the instruments at each workstation .
TRUST COMPUTATION FOR THE MANUFACTURING PROCESS
In this use case , each camera , sensor , application , network connection and worker schedule , among others , possesses observed values ( attributes ) that can be used as input into the Trust System to calculate an overall Trust Score . If any one of those metrics changes at any instant , the Trust System
