  • An iterative solution technique for capacitated two-stage time
           minimization transportation problem

    • Free pre-print version: Loading...

      Abstract: Capacitated two-stage time minimization transportation problem is an important optimization problem arising in industries. In literature, there is only one approach to solving this problem, but it has a deficiency of resulting in memory overflow in implementation on computer for large scale instances. In this paper, this problem is reduced to a series of finding the feasible flow in a network with lower and upper arc capacities, and two iterative algorithms are proposed as more robust solution method for this problem as compared to the existing approach. It is proved that both iterative algorithms find the optimal solution to this problem in a polynomial time. Due to fully utilizing the network structure characteristics inherent to this problem, both iterative algorithms have the advantage of easy implementation on computer and high computational efficiency, and successfully overcome the deficiency of existing approach. Computational experiments validate that as compared to the existing approach, both iterative algorithms are efficient and more robust method to solve this problem, where one iterative algorithm significantly outperforms the other in terms of computational time, especially for large scale instances.

      Abstract: Invented some 65 years ago in a seminal paper by Marguerite Straus-Frank and Philip Wolfe, the Frank–Wolfe method recently enjoys a remarkable revival, fuelled by the need of fast and reliable first-order optimization methods in Data Science and other relevant application areas. This review tries to explain the success of this approach by illustrating versatility and applicability in a wide range of contexts, combined with an account on recent progress in variants, improving on both the speed and efficiency of this surprisingly simple principle of first-order optimization.

  • A periodic review policy for a coordinated single vendor-multiple buyers
           supply chain with controllable lead time and distribution-free approach

    • Free pre-print version: Loading...

      Abstract: In this paper, we study a single vendor-multiple buyer integrated inventory model with controllable lead time and backorders-lost sales mixture. Each buyer adopts a periodic review policy in which the review period is an integer fraction of the production cycle time of the vendor. To reflect the practical circumstance characterized by the lack of complete information about the demand distribution, we assume that only the first two moments of the demand during the protection interval are known. The long-run expected total cost per time unit is derived, which includes stockout costs. The problem is to determine the length of the inventory cycle of the vendor, the produce-up-to level for the vendor, the replenishment policy of each buyer, and the length of lead times that minimize the cost function under the minimax distribution-free approach. Two alternative heuristics are proposed. Numerical experiments have been carried out to investigate the performance of the heuristics and to study the sensitivity of the model.

  • Improving ADMMs for solving doubly nonnegative programs through dual
           factorization

    • Free pre-print version: Loading...

      Abstract: Alternating direction methods of multipliers (ADMMs) are popular approaches to handle large scale semidefinite programs that gained attention during the past decade. In this paper, we focus on solving doubly nonnegative programs (DNN), which are semidefinite programs where the elements of the matrix variable are constrained to be nonnegative. Starting from two algorithms already proposed in the literature on conic programming, we introduce two new ADMMs by employing a factorization of the dual variable. It is well known that first order methods are not suitable to compute high precision optimal solutions, however an optimal solution of moderate precision often suffices to get high quality lower bounds on the primal optimal objective function value. We present methods to obtain such bounds by either perturbing the dual objective function value or by constructing a dual feasible solution from a dual approximate optimal solution. Both procedures can be used as a post-processing phase in our ADMMs. Numerical results for DNNs that are relaxations of the stable set problem are presented. They show the impact of using the factorization of the dual variable in order to improve the progress towards the optimal solution within an iteration of the ADMM. This decreases the number of iterations as well as the CPU time to solve the DNN to a given precision. The experiments also demonstrate that within a computationally cheap post-processing, we can compute bounds that are close to the optimal value even if the DNN was solved to moderate precision only. This makes ADMMs applicable also within a branch-and-bound algorithm.

      Abstract: When all objectives have a common minimum the existence of this ideal solution directly yields all efficient solutions of the corresponding multi-objective problem, as well as all minimising solutions of any positively weighted sum of these objectives. Some of the classical results in location theory are easy consequences of this simple property, while the same methodology also leads to some lesser known or new results.

  • Coordination of VMI supply chain with replenishment tactic under risk
           aversion and sales effort

    • Free pre-print version: Loading...

      Abstract: This paper considers a vendor-managed inventory (VMI) supply chain consisting of a risk-averse supplier and a risk-neutral retailer engaging in sales promoting efforts. Under the conditional risk at value, we examine three different types of contracts with the replenishment option for coordinating the VMI supply chain, namely, a risk diversification and cost sharing (RDCS) contract, an option and cost sharing contract, and a subsidy and cost sharing contract. Firstly, we derive the optimal production strategy and analyze the capability of each of the proposed contracts in coordinating the VMI supply chain. We find that all of those contracts can achieve coordination of the supply chain with Pareto improvement. Secondly, we also show that both the supplier and the retailer prefer the RDCS contract over the other two contracts. Finally, we use numerical experiments to analyze the impact of risk aversion on contracts’ parameters.

  • The grid based approach, a fast local evaluation technique for line
           planning

    • Free pre-print version: Loading...

      Abstract: Line planning is one of the important steps in the public transit planning process. It is a difficult combinatorial problem with an enormous search space. For networks from practice, which are typically large and have more complex constraints, it takes an unreasonable amount of time to find good solutions with the current methods. When the objective is to minimize passenger travel time, most of the calculation time is spent on solving the passenger routing sub-problem. This paper proposes a local evaluation technique to significantly speed up this most critical component. A change is assumed to have its biggest impact on passengers already travelling close to the change. This idea is implemented by putting a grid over the network and only re-evaluating the part of the network around the change, while still taking into account all passengers. This results in a smaller computation time for each passenger routing, with only a limited loss of quality, and it allows more iterations. On a number of benchmark instances, the results obtained by the grid approach are compared to the same algorithm without any local evaluation. The grid approach is significantly faster and allows to perform 5–20 times more evaluations per second, while having a minimal loss of quality per evaluation. When the available calculation time is limited, the grid based approach obtains the best solutions. On the larger benchmark instances, the grid based approach can use more complex neighborhoods resulting in even better solutions. The method is very flexible and can be integrated in many line planning algorithms and probably even in algorithms for other network problems.

  • Simple ranking method using reference profiles: incremental elicitation of
           the preference parameters

    • Free pre-print version: Loading...

      Abstract: The Simple Ranking Method using Reference Profiles (or SRMP) is a Multi-Criteria Decision Aiding technique based on the outranking paradigm, which allows to rank decision alternatives according to the preferences of a decision maker (DM). Inferring the preference parameters of such a model can lead to a cognitive fatigue of the DM, who is often asked to express several preferential statements about pairs of alternatives during the elicitation process. To limit the DM’s effort, we propose in this work an incremental elicitation process to select informative pairs of alternatives to be presented to the DM sequentially with the aim of refining the SRMP model until a robust recommendation can be made. We study several different heuristics for selecting the pair of alternatives to be submitted to the DM at each step. Following extensive numerical experiments we identify one of the proposed heuristics as performing significantly better than the others and we provide several guidelines for its use in practice.

  • Cross Malmquist Productivity Index in Data Envelopment Analysis

    • Free pre-print version: Loading...

      Abstract: In Data Envelopment Analysis (DEA), the Malmquist Productivity Index (MPI) is an important instrument used to assess dynamic performance. In this paper, to deal with overestimation, to increase rationality, and to reduce dependence on self-assessment results, we equip MPI with the cross-evaluation strategy. The MPI values measured from self and peer points of view are not the same necessarily, even significantly different or strongly inconsistent, and none of them can be ignored. Therefore, to match the results for the two common up-down and bottom-up strategies in building MPI indices, and to retain the multiplicative structure at the aggregate level, we use the geometric mean to aggregate the self and peer MPIs. Because the MPI indices of all units are calculated with several common bundle weights, the resulting values are consistent and therefore comparable. We will show the usability of the proposed method using a real example of 20 branches of an Iranian bank in 2017–2018.

      Abstract: Learning how to model a problem described in natural language as a linear program requires students to practice using various and numerous exercises. Moreover, immediate feedback on the validity of their solutions helps a better and faster understanding. In this paper, we present an idea on how students and teachers can automatically evaluate linear programming models. We also describe how this idea was implemented on the learning platform caseine.org and is now used by hundreds of students from various universities.

      Abstract: The concept of balance plays an important role in many combinatorial optimization problems. Yet there exist various ways of expressing balance, and it is not always obvious how best to achieve it. In this methodology-focused paper, we study three cases where its integration is deficient and analyze the causes of these inadequacies. We examine the characteristics and performance of the measures of balance used in these cases, and provide general guidelines regarding the choice of a measure.

  • A note on ELECTRE TRI-nB with few limiting profiles

    • Free pre-print version: Loading...

      Abstract: ELECTRE TRI-nB is a method designed to sort alternatives evaluated on several attributes into ordered categories. It is an extension of ELECTRE TRI-B that uses several limiting profiles, instead of one, to delimit each category. In a previous paper we have characterized the ordered partitions that can be obtained with ELECTRE TRI-nB, using a simple axiom called linearity. The simplicity of this characterization crucially rests on the possibility to use as many limiting profiles as we like to delimit a category. This is not completely realistic and there is a need to study models in which the number of limiting profiles delimiting each category is restricted. This note starts the investigation of such models. We specifically study the case of models using one or two profiles together with an outranking relation based on unanimity.

      Abstract: In this paper we wish to tackle stochastic programs affected by ambiguity about the probability law that governs their uncertain parameters. Using optimal transport theory, we construct an ambiguity set that exploits the knowledge about the distribution of the uncertain parameters, which is provided by: (1) sample data and (2) a-priori information on the order among the probabilities that the true data-generating distribution assigns to some regions of its support set. This type of order is enforced by means of order cone constraints and can encode a wide range of information on the shape of the probability distribution of the uncertain parameters such as information related to monotonicity or multi-modality. We seek decisions that are distributionally robust. In a number of practical cases, the resulting distributionally robust optimization (DRO) problem can be reformulated as a finite convex problem where the a-priori information translates into linear constraints. In addition, our method inherits the finite-sample performance guarantees of the Wasserstein-metric-based DRO approach proposed by Mohajerin Esfahani and Kuhn (Math Program 171(1–2):115–166. https://doi.org/10.1007/s10107-017-1172-1, 2018), while generalizing this and other popular DRO approaches. Finally, we have designed numerical experiments to analyze the performance of our approach with the newsvendor problem and the problem of a strategic firm competing à la Cournot in a market.
