Analyzing sensor data in supply chain automation❑ IBM’s supply chain teams proposed four stages of supply chain analytics
1) Descriptive analytics => Visualization
2) Predictive analytics => Predict events or future outcomes
3) Prescriptive analytics => what should we do
4) Cognitive analytics => deal with a human nature problem responding to the case that never happens in the past; for example, an organization answer complex questions in natural language — in the way a person or team of people might respond to a question.

How to combine sensor data for useful cases?❑ A single sensor may not be enough to derive a desired level of target estimation or hypothesis identification in supply chain applications.
❑ Therefore, multiple sensors are required to achieve a complete and accurate description of an environment or process of interest.
❑ The simple question is how to combine sensor data gathered for useful cases.

Some promising research issues❑Most fusion systems are optimistic in that they assume that all sensors are reliableand pay more attention to uncertainty modeling and fusion methods.
❑ The performance of the fusion system is, however, highly dependent on sensor performance and adaptability to the operating environment as well as ability to estimate the reliability of each sensor readings (pieces of evidence).
❑ Two issues that need to be considered❑ The data derived from multiple sources (signals or humans) is usually imperfect (imprecise,
uncertain, and even conflicting). ❑ The imperfection and unreliability of sensor data are often attributed to technical and noise
(environmental noise, presence of unknown targets, meteorological conditions, etc.) factors.
❑ It needs an index for quantifying sensor performance and weighing readings.

Some promising research issues❑We can then treat such issues in Multiple Criteria Decision-Making Problem (MCDM).

Problem formulation
❑ Linguistic assessments represent uncertain and vagueness of information due to human’s ability.
❑ Linguistic values are totally different from numeric ones.
❑ A computing with word (CW) methodology is necessary!

Future Directions ❑ It is not effective to define a unique linguistic term set to be used by alldecision-makers (Herrera et al, 2016; Jiang et al., 2017).
30
Future Directions ❑ To extend a further study to application feedback stage in order for continuous improvement (Wu et al., 2012).
❑ So we aim to gather more experts’ opinions in order to build a software-based decision support system (DSS)
