This paper discuss the operational efficiency of Perishable Product Supply Chain (PPSC) in context of Petri Net (PN) modeling technique. The operational efficiency is classified into: inventory management, logistics, information sharing and supply chain risk among different stages of supply chain with coordination and monitoring through traceability and PPSC risk management. This classification of operational efficiency will allow the industrial practitioners and academicians to decide on the suitable petri net technique for the problem identified. This paper discuss the research directions of application of Petri Net in PPSC (operational efficiency). In addition, paper provides future directions for operational efficiency in PPSC and are as follows: 1) modelling PPSC with uncertainty, 2) reducing complexity in PPSC, 3) integration of PN modelling with emerging technology, 4) PN involvement in information flow and traceability and 5) application of PN modelling in decision making.
