Optimal ordering policy and preservation technology for deteriorating items with maximum lifetime under a resilient hybrid payment decision

This study demonstrates an inventory system with items changing value over time under various realistic environments. It is assumed that the time-varying deterioration rate depending on maximum lifetime of and exceeding are regarded as scarp no longer serviceable. As a result, retailer will invest in preservation technology to reduce reckless deterioration. On other hand, receives upstream advance-cash-credit payment plan from supplier while offering downstream cash-credit customers stimulate sales. above description, we incorporate relevant phenomena into proposed model, then primary objective determine replenishment cycle which maximizes retailer's total profit. Consequently, contributions this have three parts follows: (1) Addressing economic (total profit) (preservation technology) impacts simultaneously; (2) The propositions theorems derived along solution procedure; (3) proved optimal not only exists but also unique some conditions. Next, algorithm developed simplifies search for sustainable ordering strategies. Numerical examples sensitivity analysis elaborated validate mathematical formulation. Findings summarized managerial implications discussed.
