A stochastic model for developing speculation-postponement strategies and modularization concepts in the global supply chain with demand uncertainty

Integrated operations planning model for the automotive wiring industry

“…Some works have focused on single-stage production with a single product and single material, as exemplified by the research conducted by Kumar et al [ 13 ], Masudin et al [ 14 ], and Fauza et al [ 15 ], El-Baz and Taha [ 16 ] and Duan and Ventura [ 17 ]. Other studies have considered more complex scenarios involving multi-stage, multi-product, and/or multi-material settings, as demonstrated by the works of Fauza et al [ 18 ], Utama et al [ 19 ], Kaur et al [ 20 ], Budiman and Rau [ 21 ], Nagar et al [ 22 ] and Susarla and Karimi [ 23 ].…”

“…In the other hand, some papers investigated the case of multi-stage production with single product [ 18 , 19 ] or multi-products [ [20] , [21] , [22] , [23] ].…”

“…Kaur et al [ 20 ], and Budiman and Rau [ 21 ] presented stochastic models with dynamic time. While Nagar et al [ 22 ] investigated multi-objective issues to optimize profit, service, and downside risk.…”

“…Different variants of this problem have been investigated: some works involve a single-stage production with multiple products [ [7] , [8] , [9] , [10] , [11] , [12] ], while others consider a specific product [ [13] , [14] , [15] , [16] , [17] ]. Some other papers study the case of multi-stage production with single product [ 18 , 19 ] or multi-products [ [20] , [21] , [22] , [23] ].…”

Implementation of engineering techniques for reducing waste in Warehousing: A case study in a Peruvian Food Company

“…In the national context, excess food product waste has negative impacts, both economically for the organization and on a general scale in Peru. This impact is measured through the wastage ratio, which represents the proportion of food waste respect to the total product sales [4]. It was found that the magnitude of this indicator amounted to 0.60%, in relation to the food sector, in 2021, increasing by 0.42% in the last four years [5].…”
