Globalization led to increase in demand for Fourth-Party Logistics (4PL) which
emphasizes on enhancing value proposition compared to cost reduction in Third-Party
Logistics (3PL). In particular, 4PL development has been dependent on transaction center
which integrates cross-segment (for example: suppliers and logistics service providers)
trading partners working towards common goal. As the strength of transaction center lies
in selecting and coordinating cross-segment trading partners (Kumar et al., 2013), prior
information of risk can help the coordinator to minimize supply disruptions. According
to Aberdeen research, 80% of the executives faced supply disruptions to manage their
distribution network efficiently (McCormack, 2007). Moreover, disruption risk acts as one
of the sources for bullwhip effect in a supply chain. Additionally, individual trading
partners synthesize their own metrics and procedures for assessing and predicting risk.Therefore, the transaction center coordinator needs to assess risk before performing crosssegment
integration in order to provide optimal 4PL solutions. Hence, assessment of risk
in a proactive manner ensures consistent supply. Taking a cue from this, proactive riskpredictive
model using Partial Least Square (PLS) regression and Neural Network (NN)
approach was proposed. The NN’s ability to model linear and nonlinear relationships,
irrespective of the dataset category, was considered as the rationale for application of this
methodology. In the process of building NN, datasets were normalized and optimized to
match actual and predictive Risk Probability Index (RPI). In particular, this index was
estimated by multiplying scaling factors of discrete risk event categories and probability
of occurrence. In principle, the model was developed in two phases. Firstly, risk assessment
was carried out using Cormack’s model with six different risk enablers. In the second
phase, predictive model was synthesized using NN methodology. Furthermore, the
network was trained till actual and predictive RPI match through feedforward and back
propagation techniques (Glenn, 2007). Lastly, viability of the recommended risk model
was verified considering casting suppliers of a leading tiller and tractor manufacturing
company in India. In summary, estimation of risk in a proactive manner for 4PL
transaction center was highlighted.
