Post sale service is an integral part of the supply chain system. The main aim of this article is to reduce the warranty failure service cost and increase customer satisfaction. This research first aims to determine the root cause of the warranty failure and thereafter sends feedback to manufacturers to avoid future product failures. This task is accomplished by the proposed multi-agent framework which inherits number of specific task oriented autonomous agents such as service agent, fault diagnosis agent, manufacturing agent and corporate memory agent. The suggested decision by the multi-agent framework is guided by the hybrid CFGTSA algorithm. This will help manufacturing firms to execute the manufacturing processes smoothly and reduce the service supply chain cost.
