A single-consignor multi-consignee multi-item model with permissible payment delay, delayed shipment and variable lead time under consignment stock policy

This article proposes a two-level fuzzy supply chain inventory model, in which single consignor delivers multiple items to the consignees with consignment stock agreement. The lead time is incorporated into model and considered variable for obtaining optimal replenishment decisions. In addition, crashing cost employed reduce duration. investigates four different cases under controllable analyze best strategy, focusing on two delays such as delay-in-payments delay-in-shipment. all cases, associated costs are treated trapezoidal number, signed distance method defuzzify cost. An efficient optimization technique adopted find solution chain. Four numerical experiments conducted illustrate cases. Any one of these experimental results will provide ideal performance business policy. Finally, managerial insights, conclusion future direction this provided.
