Sustainable and resilience planning for the supply chain of online hyperlocal grocery services
برنامه ریزی پایدار و انعطاف پذیر برای زنجیره تأمین خدمات مواد غذایی آنلاین بیش از حد محلی-2021 In an uncertain Supply Chain (SC) environment dealing with suppliers and transport-level
disruptions in addition to fulfilling customers’ requirements is a complex task. Such
challenges are more taxing in case of perishable products SCs. The concurrent effect of all
such events affects the economic stability of SC and impedes sustainability on a longer
planning horizon. The proposed study presents a case example of e-commerce based SC
addressing an operational and distribution planning problem. For this purpose, the study
simulates online grocery business operations by proposing a mixed-integer linear
programming problem to minimize SCs expected cost. It includes the costs of purchase,
transportation, supply-demand mismatch, and cost of economic loss due to the perishable
nature of the products. Computational analysis is performed to manifest the performance of
the proposed model considering the dataset of a hyperlocal distribution service. The study
evaluates the utility of resilience and sustainable strategies to minimize expected economic
costs and reduce environmental impacts by effectively managing waste. A backup strategy is
devised to promote a resilient SC planning to fight the risk of disruptions and operational
failures. Additionally, economic sustainability is achieved by implementing various
markdown policies and waste minimization strategies. A sensitivity analysis using MonteCarlo simulation is presented to recognize the impact of operational risk, demand uncertainty,
and perishability on the expected cost. Majorly, it contributes to the scant literature of
quantitative modeling for the production and distribution of food SC to promote resiliently
sustainable planning. Further, the resilient and sustainable strategies, procurement policies,
penalty assessment, and markdown due to perishability are some of the key contributions of
the study. The discussion provides plenty of opportunities to pursue future studies in
operational and distribution management of e-commerce SCs.
