  • Which uncertainty is important in multistage stochastic programmes? A case
           from maritime transportation †
    • Authors: Pantuso G; Fagerholt K, Wallace SW.
      First page: 5
      Abstract: Given that the scope of stochastic programming is to suggest good decisions and not to estimate probability distributions, we demonstrate in this paper how to numerically evaluate which properties of random variables are more important to capture in a stochastic programming model. Such analysis, performed before data collection, can indicate which information should be primarily sought, and which is not critical for the final decision. We apply the analysis to a real-life instance of the maritime fleet renewal. Results show that some properties of the stochastic phenomena, such as the correlation between random variables, have very little influence on the final decision.

  • A two-stage stochastic integer programming model for air traffic flow
           management
    • Authors: Corolli L; Lulli G, Ntaimo L, et al.
      First page: 19
      Abstract: The high cost of flight delays for airlines has motivated scientific research in air traffic flow management (ATFM). The majority of ATFM models in the literature are deterministic and do not take into account stochastic factors such as weather. In this paper, new stochastic programming models for ATFM are proposed. The models include as tactical control options: ground holding, airborne holding and rerouting. To solve the models, a new heuristic method that takes advantage of the problem structure is derived and illustrated. Computational results show that the heuristic method provides practical computation times. Furthermore, the value of the stochastic solution is up to 14% for cases where adverse weather affects a significant part of the network. This implies that using the proposed approach to make air traffic flow decisions can lead to tangible monetary benefits for airlines.

  • A stochastic programming approach for the traveling purchaser problem
    • Authors: Beraldi P; Bruni M, Manerba D, et al.
      First page: 41
      Abstract: The deterministic traveling purchaser problem (TPP) aims to select a subset of suppliers, offering products at different prices and quantities, to satisfy demand while minimizing travelling and purchasing costs. In this paper, we study a variant of the TPP in which both the available quantities and the purchasing prices are uncertain. This more challenging version of the problem, TPP under uncertainty, allows a purchaser to protect himself against risks of insufficient demand fulfilment and to exploit the benefits of procurement at lower prices. We introduce a two-stage stochastic programming formulation of the problem and we present a tailored solution approach based on a Branch-and-Cut method and on a heuristic approach to find good initial solutions. Extensive computational experiments show the efficiency of the proposed approach in finding the optimal solution of the deterministic equivalent problem for instances with up to 75 suppliers, 50 products and 200 scenarios in less than 2 h.

  • A progressive hedging method for the multi-path travelling salesman

    • Authors: Perboli G; Gobbato L, Maggioni F.

      Abstract: In this paper, we consider a recently introduced problem specifically designed for Smart Cities and City Logistics applications: the multi-path travelling salesman problem with stochastic travel costs $({\rm mpTSP}_s)$. The ${\rm mpTSP}_s$ is a variant of the TSP problem where a set of paths exists between any two nodes and each path is characterized by a random travel time. We propose a two-stage stochastic programming formulation where tour design makes up the first stage, while recourse decisions related to the choice of the path to follow are made in the second stage. To solve this formulation, we propose a heuristic method inspired by the Progressive Hedging (PH) algorithm of Rockafellar & Wets (1991, Scenarios and policy aggregation in optimization under uncertainty. Math. Oper. Res., 16, 119–147.) We then benchmark the solution method by solving model instances derived from the traffic speed sensor network of the city of Turin. Furthermore, the impact of the stochastic travel time costs on the problem solution is examined, showing the benefits of the proposed methodology in both solution quality and computational effort when compared to solving the deterministic equivalent formulation using a commercial solver.

  • A class of efficiently solvable multistage optimization problems under
           uncertainty and applications
    • Authors: Minoux M.
      First page: 87
      Abstract: We investigate a class of specially structured multistage robust optimization problems under uncertainty for which efficient computation of exact optimal robust strategies is possible. As an essential feature of this class of problems, we introduce the concept of a state-space representable uncertainty set, based on an underlying graph-theoretic structure. This concept is shown to extend several previously proposed types of uncertainty sets, and naturally lends itself to compact representations of scenario sets of huge cardinality. It is also convenient to represent uncertainty sets featuring dependence among the realizations of the uncertain parameters in successive time periods. Computational results are reported on a series of test problems featuring up to 50 time periods, in connection with an application to a multiperiod energy production planning problem. These results are shown to provide an experimental basis for comparing optimal robust strategies against optimal solutions derived from a related robust 2-stage model.

  • Integrating multi-stage stochastic programming and machine learning for
           the evaluation of policies in the electricity portfolio problem
    • Authors: Murgia G; Sbrilli S.
      First page: 109
      Abstract: Multi-stage stochastic programming can support large consumers in developing electricity portfolios that balance the expected total cost and the risk level. Nevertheless, the adoption of multi-stage stochastic programming in real-world problems is often made difficult by the high computational burden required. In this paper, we present an innovative approach, called General Policy Function Approximation, that provides good solutions to the electricity portfolio problem in a limited computational time, owing to the integration of multi-stage stochastic programming and machine learning. Our approach improves the Policy Function Approximation (PFA) approach proposed by Defourny et al. [(2012). Multi-stage stochastic programming: A scenario tree-based approach to planning under uncertainty. Decision Theory Models for Applications in Artificial Intelligence (L. E. Sucar, E. Morales, F. Eduardo & J. Hoey eds). vol. 6. Hershey: IGI Global, pp. 97–144], by developing a single policy function generated from a larger amount of data. Owing to a realistic computational campaign, we show that our approach outperforms PFA both in terms of quality of the policy obtained, and in terms of time required.

  • Stochastic programming bilevel models for service provision with a
           balancing coordinator
    • Authors: Pisciella P; Gaivoronski AA.
      First page: 131
      Abstract: This paper introduces a framework for the quantitative analysis of collaborative service platforms. Services built around platforms require the coordinated collaboration of several independent agents, each from a different field or area of expertise and each providing one or more components to the overall service. One of these agents takes the further role of platform coordinator, whose role consists in assembling the services from components provided by other agents and sharing the revenue between the participants. The agents decide which services to make a contribution to by selecting service portfolios that maximize their expected profit under constraints on risk and capacity. The coordinator selects the revenue-sharing scheme that balances the offers from other agents and ensures the functioning of the platform. We develop two stochastic optimization models with bilevel structure for the analysis of the collaborative service platform provision, analyse the properties of the solutions and provide numerical experiments that show the qualitative difference of the profit$/$risk trade-off in the multiagent case compared with the classical single agent case.
