A multi-period multi-modal stochastic supply chain model under COVID pandemic: A poultry industry case study in Mississippi

Abstract

The poultry industry is one of the most important agricultural sectors, which constitutes a significant part of the per capita consumption of protein and meat. Integrating operations of poultry industry sections including production, distribution and consumption becomes vital. Although the proper poultry supply chain has been established and made plenty of benefits for a long time, the global outbreak of COVID-19 shows that operations under pandemic are still challenge for the poultry industry. In this paper, the impacts of pandemic on poultry industry is investigated by developing a multi-period multi-modal stochastic poultry supply chain. Two models are developed aiming to mitigate the negative effects of pandemic occurrence through product stocking policy. In the first model, distribution system is in accordance with a multi-component structure, while the second model allows direct connections between suppliers (farmers) and demanders (customers). In both models, poultry productions are negatively affected by COVID 19. Due to the complexity of the model, a hybrid solution approach based on Branch and Cut and Dynamic Programming is developed. To validate the performance of the proposed model and solution procedure, a case study on the broiler industry in the state of Mississippi is performed. The results show that storing poultry products in the pre-pandemic along with direct logistics during pandemic period can save the broiler supply chain cost up to 30%.

The Impact of the COVID-19 Pandemic on Consumers’ Preferences for Wood Furniture: An Accounting Perspective

“…Since the outbreak of the COVID-19 pandemic, researchers and policymakers have been interested in research on the impact of the COVID-19 pandemic on industries, and many studies have analyzed industry data. These include studies of the tourist industry [23][24][25][26][27][28][29], hotel industry [24,28,[30][31][32], energy industry [33][34][35], cruise industry [27,36,37], aviation industry [38][39][40], restaurant industry [32,41], food industry [42][43][44][45], poultry industry [46][47][48], IT services industry [49], electricity industry [50,51], tobacco industry [52], insurance industry [53,54], construction industry [55,56], and forestry and wood industry [57,58]. The above-mentioned research mainly focuses on the negative impact of the pandemic on public consumption behavior, society, or related industries.…”

A reliable emergency logistics network for COVID-19 considering the uncertain time-varying demands

“…Considering the time-varying nature of demands, Yarmand et al (2014) use a simulation model to capture the epidemic dynamics in each region and then propose a two-stage stochastic linear program to determine the vaccine allocation plans. Assuming the demand at each period is stochastic and follows a normal distribution, Yazdekhasti et al (2021) propose a multi-period multi-modal stochastic location-transportation model. Fadaki et al (2022) propose a multi-period vaccine allocation model incorporating transshipment between facilities.…”

Fluctuations and disparity in broiler and carcass price before during and after covid-19 pandemic in Indonesia

“…Furthermore, its adverse effects have extended into the poultry industry, creating significant challenges across various segments of the supply chain. From the perspective of producers, the decrease in consumption demand has led to a corresponding decline in poultry production [ 4 ].…”

“…In the USA, the impact of COVID-19 was also felt by workers in the meat and poultry processing industry [ 22 ]. DOC production in the US decreased significantly in April and May 2020 compared to the previous year [ 4 ]. Consequently, the global COVID-19 pandemic had a significant impact on broiler farms, especially the commodity price.…”

“…These include studies conducted by Ref. [ 4 ] in Mississippi [ 19 ], in Myanmar [ 37 ], in the European region, and [ 38 ] in Indonesia. Research results in Indonesia show that there is negative price transmission at the farmer and consumer levels as a result of market power by the poultry industry [ 39 ].…”
