We solve a periodic supply vessel planning problem under demand and weather uncertainty, arising in offshore of oil gas production. Our study is motivated by the case Norwegian energy operator Equinor which supplied us with data. The aim to determine an optimal fleet composition least-cost schedule uncertain at installations conditions. present methodology incorporating metaheuristic within dis...

The price-setting newsvendor problem, which models the economic trade-offs associated with uncertain demand of a perishable product, is fundamental to supply chain analysis. However, in settings such as agriculture, there is significant economic risk associated with supply uncertainty. We analyze how risk aversion and the source of uncertainty—demand and/or supply—affect tractability and optima...

This paper studies the issue of uncertainty in the ambulance location problem to cover the maximum number of demand points in a city. The work is based on the double standard model (DSM), a popular coverage model where two radii are considered to cover a percentage of the demand points twice. Uncertainty is introduced in the expected travel time between an ambulance and a demand point, before c...

15. Supplementary Notes Supported by general revenues from the State of Texas. 16. Abstract Since transportation infrastructure projects have a lifetime of many decades, project developers must consider not only the current demand for the project but also the future demand. Future demand is of course uncertain and should be treated as such during project design. Previous research for Southwest ...

In network investments, much of the real options value may reside “in” identifying the proper configuration to develop, in terms of the timing and sizing of its deployment. A longer-term perspective, with a treatment of uncertainty that moves beyond simply increasing deterministic specifications, has the potential to improve the design of networked infrastructures, such as power transmission ne...

Addressing demand uncertainty is a research focus in supply chain management in recent years. In this paper, a new postponement strategy is applied. Postponement has been appreciated recently, especially in the manufacturing period of realizing mass customization. It has also been much used to respond to the demand uncertainty and usually considered in the planning period. However, the decision...
