Port Call Optimization at a Ferry Terminal with Stochastic Servicing Time and Additional Visits

open access: yesJournal of Marine Science and Engineering, 2023
Ferry shipping is an indispensable method of public transportation, especially in areas with well-developed river systems or coastal areas. The increasing demand for transport requires additional visits and introduces the problem of ship visit schedule ...

A multi-stage stochastic integer programming approach for a multi-echelon lot-sizing problem with returns and lost sales

open access: yesComputers & Operations Research, 2020
We consider an uncapacitated multi-item multi-echelon lot-sizing problem within a remanufacturing system involving three production echelons: disassembly, refurbishing and reassembly.

Integer set reduction for stochastic mixed-integer programming

open access: yesComputational Optimization and Applications, 2023
Two-stage stochastic mixed-integer programming (SMIP) problems with general integer variables in the second-stage are generally difficult to solve. This paper develops the theory of integer set reduction for characterizing the subset of the convex hull of feasible integer points of the second-stage subproblem which can be used for solving the SMIP. The

A stochastic dual dynamic integer programming based approach for remanufacturing planning under uncertainty

open access: yesInternational Journal of Production Research, 2022
We seek to optimize the production planning of a three-echelon remanufacturing system under uncertain input data. We consider a multi-stage stochastic integer programming approach and use scenario trees to represent the uncertain information structure ...
