A machine learning model with linear and quadratic regression for designing pharmaceutical supply chains with soft time windows and perishable products

Rekabi, Shabnam; Sazvar, Zeinab; Goodarzian, Fariba - In: Decision analytics journal 9 (2023), pp. 1-11

Product perishability is an important problem in Pharmaceutical Supply Chains (PSC). Demand perishability and unpredictability add enormous complexity to successfully implementing efficient Pharmaceutical Supply Chain Network Design (PSCND). This study develops a mathematical model for the...

The trade-off between fixed vehicle costs and time-dependent arrival penalties in a routing problem

Bhusiri, Narath; Qureshi, Ali Gul; Taniguchi, Eiichi - In: Transportation Research Part E: Logistics and … 62 (2014) C, pp. 1-22

This paper introduces the vehicle routing problem with soft time windows (VRPSTW) in which problem definition differs from ones previously defined in literature. Branch-and-price approach is employed, resulting in a set partitioning master problem and its new subproblem. Novel techniques are...
