  • Functional law of the iterated logarithm for multi-server queues with
           batch arrivals and customer feedback
    • Authors: Yongjiang Guo; Yunan Liu; Renhu Pei
      Abstract: A functional law of the iterated logarithm (FLIL) and its corresponding law of the iterated logarithm (LIL) are established for a multi-server queue with batch arrivals and customer feedback. The FLIL and LIL, which quantify the magnitude of asymptotic fluctuations of the stochastic processes around their mean values, are developed in three cases: underloaded, critically loaded and overloaded, for five performance measures: queue length, workload, busy time, idle time and departure process. Both FLIL and LIL are proved using an approach based on strong approximations.

  • Interaction of fiscal and monetary policy in a monetary union under the
           zero lower bound constraint
    • Authors: Stefanie Flotho
      Abstract: This paper analyses the interaction of monetary and fiscal policies in a dynamic stochastic general equilibrium model of a monetary union where conventional monetary policy is restricted by the binding zero lower bound constraint. We use the OccBin toolkit to analyze the performance of optimally set monetary and fiscal policies and compare outcomes with simple rules for government spending or the interest rate. Government spending are set independently from each other. We make several findings. First, fiscal policy plays an active role in stabilizing the economy under the binding zero lower bound constraint. Second, properly designed fiscal policy can even shorten the duration of the binding constraint. Third, coordination of policies is not always preferable.

  • Event classification and location prediction from tweets during disasters
    • Authors: Jyoti Prakash Singh; Yogesh K. Dwivedi; Nripendra P. Rana; Abhinav Kumar; Kawaljeet Kaur Kapoor
      Abstract: Social media is a platform to express one’s view in real time. This real time nature of social media makes it an attractive tool for disaster management, as both victims and officials can put their problems and solutions at the same place in real time. We investigate the Twitter post in a flood related disaster and propose an algorithm to identify victims asking for help. The developed system takes tweets as inputs and categorizes them into high or low priority tweets. User location of high priority tweets with no location information is predicted based on historical locations of the users using the Markov model. The system is working well, with its classification accuracy of 81%, and location prediction accuracy of 87%. The present system can be extended for use in other natural disaster situations, such as earthquake, tsunami, etc., as well as man-made disasters such as riots, terrorist attacks etc. The present system is first of its kind, aimed at helping victims during disasters based on their tweets.

  • Typology and literature review for dial-a-ride problems
    • Authors: Yves Molenbruch; Kris Braekers; An Caris
      Abstract: Dial-a-ride problems consist of designing vehicle routes and time schedules in a system of demand-dependent, collective people transportation. In the standard problem, operational costs are minimized, subject to full demand satisfaction and service level requirements. However, to enhance the practical applicability of solution methods, authors increasingly focus on problem variants that adopt additional real-life characteristics. First, this work introduces an up-to-date classification that distinguishes multiple categories of real-life characteristics. Second, the wide range of solution methods proposed in the literature is reviewed in a structured manner. Although the existing literature is reviewed exhaustively, specific attention is devoted to recent developments. Third, an extensive overview table provides full details on all problem characteristics and solution methods applied in each paper discussed. Fourth, lacunae in research conducted to date and opportunities for future work are identified.

      Abstract: In the classical Travelling Salesman Problem (TSP), the objective function sums the costs for travelling from one city to the next city along the tour. In the q-stripe TSP with \(q\ge 1\) , the objective function sums the costs for travelling from one city to each of the next q cities in the tour. The resulting q-stripe TSP generalizes the TSP and forms a special case of the quadratic assignment problem. We analyze the computational complexity of the q-stripe TSP for various classes of specially structured distance matrices. We derive NP-hardness results as well as polynomially solvable cases. One of our main results generalizes a well-known theorem of Kalmanson from the classical TSP to the q-stripe TSP.

  • Managing facility disruption in hub-and-spoke networks: formulations and
           efficient solution methods
    • Authors: Nader Azizi
      Abstract: Hub disruption result in substantially higher transportation cost and customer dissatisfaction. In this study, first a mathematical model to design hub-and-spoke networks under hub failure is presented. For a fast and inexpensive recovery, the proposed model constructs networks in which every single demand point will have a backup hub to be served from in case of disruption. The problem is formulated as a mixed integer quadratic program in a way that could be linearized without significantly increasing the number of variables. To further ease the model’ computational burden, indicator constraints are employed in the linearized model. The resulting formulation produced optimal solutions for small and some medium size instances. To tackle large problems, three efficient particle swarm optimisation-based metaheuristics which incorporate efficient solution representation, short-term memory and special crossover operator are proposed. We present the results for two scenarios relating to high and low probabilities of hub failures and provide managerial insight. The computational results, using problem instances with various sizes taken from CAB and TR datasets, confirm the effectiveness and efficiency of the proposed problem formulation and our new solution techniques.

  • Optimization of two-stage location–routing–inventory problem with
           time-windows in food distribution network
    • Authors: Chen Chao; Tian Zhihui; Yao Baozhen
      Abstract: High transportation cost and low service quality are common weaknesses in different logistics networks, especially in food delivery. Due to its perishable features, the quality of the food will deteriorate during the while delivery process. In this paper, a two-stage location–routing–inventory problem with time windows (2S-LRITW) for food products is proposed. The first stage corresponds to a location–routing–inventory problem with time windows and the second stage is the transportation problem with vehicle capacity constraints. The problem is formulated as a mixed integer-programming model. Then a hybrid heuristic is proposed, in which distance-based clustering approach, mutation operation and the relocate exchange method are introduced to improve performance of algorithm. At last, the hybrid heuristic was tested using several cases, including some small instances and a real-life case. The results show that the distance-based clustering approach can efficiently improve the convergence speed. And the IACO and the relocate exchange method can enlarge the search space. As a result, the hybrid heuristic is suitable for solving practical larger scale problem. Furthermore, the results also indicate that customer sequence has great effect on the object due to the energy cost considered.

  • On the optimality of coupon books
    • Authors: John G. Wilson; Jing Chen
      Abstract: Our research was motivated by the challenge that a discount airline can set prices below traditional levels. One possible response for the traditional airline is to offer a book of coupons at a fixed price, in an attempt to retain or even increase market share. Offering coupon books is a way to induce changes in customer buying practices. Here we assume that each customer acts strategically in deciding whether or not to switch airlines and whether to buy the coupon book or the regular tickets. Other than price, the number of coupons in the book provides a way to segment the market. Airlines usually have data on circumstances where no coupon books were offered, but they generally do not have the luxury of experimenting by offering coupon books and gauging the response. The focus for this work is therefore: using only the data that is currently available (from the non-coupon case), are there key indicators that can help an airline decide whether or not to offer coupon books? We demonstrate that the crucial factor is the company’s current market share, and we show how to establish a threshold market share above which coupon books should not be offered. This becomes useful when advising a manager on a course of action, as the decision can be based on knowledge of current market share and beliefs about future market share. We show that there can be a broad region in which a manager can tolerate the give and take involved in behavioral and group decision making.

  • An ILP-based local search procedure for the VRP with pickups and
           deliveries
    • Authors: Agustín Montero; Juan José Miranda-Bront; Isabel Méndez-Díaz
      Abstract: In this paper we address the Vehicle Routing Problem with Pickups and Deliveries (VRPPD), an extension of the classical Vehicle Routing Problem (VRP) where we consider precedences among customers, and develop an Integer Linear Programming (ILP) based local search procedure. We consider the capacitated one-to-one variant, where a particular precedence must be satisfied between pairs of origin-destination customers. We extend the scheme proposed in De Franceschi et al. (Math Program 105(2–3):471–499, 2006) for the Distance-Constrained Capacitated VRP, which has been successfully applied to other variants of the VRP. Starting from an initial feasible solution, this scheme follows the destroy/repair paradigm where a set of vertices is removed from the routes and reinserted by solving heuristically an associated ILP formulation with an exponential number of variables, named Reallocation Model. In this research, we propose two formulations for the Reallocation Model when considering pickup and delivery constraints and compare their behavior within the framework in terms of the trade off between the quality of the solutions obtained and the computational effort required. Based on the computational experience, the proposed scheme shows good potential to be applied in practice to this kind of problems and is a good starting point to consider more complex versions of the VRPPD.

  • On component commonality for periodic review assemble-to-order systems
    • Authors: Antoine Deza; Kai Huang; Hongfeng Liang; Xiao Jiao Wang
      Abstract: Akçay and Xu (Manag Sci 50(1):99–116, 2004) studied a periodic review assemble-to-order (ATO) system with an independent base stock policy and a first-come-first-served allocation rule, where the base stock levels and the component allocation are optimized jointly. The formulation is non-convex and, thus theoretically and computationally challenging. In their computational experiments, Akçay and Xu (Manag Sci 50(1):99–116, 2004) modified the right hand side of the inventory availability constraints by substituting linear functions for piece-wise linear ones. This modification may have a significant impact for low budget levels. The optimal solutions obtained via the original formulation; that is, without the modification, include zero base stock levels for some components and indicate consequently a bias against component commonality. We study the impact of component commonality on ATO systems. We show that lowering component commonality may yield a higher type-II service level. The lower degree of component commonality is achieved via separating inventories of the same component for different products. We substantiate this property via computational and theoretical approaches. We show that for low budget levels the use of separate inventories of the same component for different products could achieve a higher reward than with shared inventories. Finally, considering a simple ATO system consisting of one component shared by two products, we characterize the budget ranges such that the use of separate inventories is beneficial, as well as the budget ranges such that component commonality is beneficial.

  • A flexible elicitation procedure for additive model scale constants
    • Authors: Adiel T. de Almeida-Filho; Adiel T. de Almeida; Ana Paula C. S. Costa
      Abstract: This paper contributes to the process of eliciting additive model scale constants in order to support choice problems, thereby reducing the effort a decision maker (DM) needs to make since partial information with regard to DM preferences can be used. Procedures related to eliciting weights without a tradeoff interpretation of weights are justified based on assumptions that DM is not able to specify fixed weight values or if DM is able to do so, this would not be reliable information. As long as partial information is provided, the flexible elicitation procedure performs dominance tests based on a linear programming problem to explore the DM’s preferences as a vector space which is built using the DM’s partial information. To provide evidence of the satisfactory performance of the flexible elicitation procedure, an empirical test is presented with results that indicate that this procedure requires less effort from DMs.

  • Two-agent-based single-machine scheduling with switchover time to minimize
           total weighted completion time and makespan objectives
    • Authors: Shesh Narayan Sahu; Yuvraj Gajpal; Swapan Debbarma
      Abstract: We consider a single-machine scheduling problem with two-agents, each with a set of non-pre-emptive jobs, where two agents compete for the use of a single processing resource. A switchover time arises whenever a job of one agent is processed after a job of another agent. Each agent wants to minimize a certain objective function, which depends upon the completion time and switchover time of their own jobs only. This paper considers the minimization of total weighted completion time of the first agent subject to an upper bound on the makespan of the second agent. We introduce some properties to the problem. The properties describe the structure of an optimal solution which is being used for developing an optimal algorithm. We propose an optimal algorithm, a simple heuristic algorithm, and a particle-swarm-based meta heuristic algorithm to solve the problem. The heuristic algorithm is based on the weighted shortest process time-first rule. The performances of the heuristic and particle swarm algorithms are evaluated on randomly generated problem instances. We perform the numerical analysis to reveal the properties of the proposed problem.

  • An EOQ model for decaying item with full advanced payment and conditional
           discount
    • Authors: Shayan Tavakoli; Ata Allah Taleizadeh
      Abstract: The classic economic order quantity model assumes that purchasing cost should be paid immediately after the delivery time. In practice, sometimes the vendors ask the buyers to prepay the entire or a percentage of the purchasing cost before delivery time. In this paper the buyer’s inventory control system for a decaying item under full prepayment scheme based on various conditions consisting of (1) no shortage, (2) full backordering shortage is allowed and (3) partial lost sale is permitted, are developed. Numerical analysis is provided to show the performance of the model and some managerial insights are presented based on the proposed solution technique and sensitivity analysis.

  • How the Great Recession affects performance: a case of Pennsylvania
           hospitals using DEA
    • Authors: Ya Chen; Justin Wang; Joe Zhu; H. David Sherman; Shin-Yi Chou
      Abstract: Health care spending usually contributes to a large part of a developed country’s economy. In 2011, the U.S. consumed about 17.7% of its GDP on health care. As one of the most significant components of the health care industry, the hospital sector plays a key role to provide healthcare services. Healthcare services industry can be affected by many factors, of which economic downturn is a crucial one. As a result, it is worth investigating the condition and state of hospital management when economic downturn occurs. This paper aims to analyze how the Great Recession affects hospital performance in Pennsylvania during the period 2005–2012 by using data envelopment analysis (DEA). Specifically, we measure efficiency for hospitals in Pennsylvania, and use several DEA models to calculate the global Malmquist index (GMI). We find that: (1) 15.4% hospitals are always efficient while 36.9% hospitals are always inefficient for all years in 2005–2012; (2) The relative distance for a group of hospitals to the frontier is almost unchanged post-recession and pre-recession; (3) The average efficiency/GMI decreases by 2.43%/3.07% from pre-recession to post-recession. The analysis indicates that hospital performance slightly decreased due to the economic downturn in Pennsylvania.

  • Pre-positioning of relief inventories for non-profit organizations: a
           newsvendor approach
    • Authors: Jingxian Chen; Liang Liang; Dong-Qing Yao
      Abstract: Developing an efficient policy to determine the inventory a non-profit organization (NPO) should stockpile to respond to potential disasters plays a vital role in humanitarian relief. Incorporating social donation and emergency spot purchasing, this paper develops a (generalized) two-stage delivery process model to characterize relief materials’ delivery after a disaster. We propose an analytical model that aims to minimize the total costs when all demands incurred by an unexpected disaster need to be fully satisfied. Moreover, we determine that the optimal solution uniquely exists and characterize the effects of key parameters. Last, this paper also develops a risk-sharing scheme, in which the NPO and the supplier jointly stockpile relief materials. Under some mild conditions, we show that implementing the scheme could increase the storage quantity and decrease the total costs simultaneously. Several numerical examples are employed to validate the model, as well as the value of the proposed risk-sharing scheme.

  • Optimal price-threshold control for battery operation with aging
           phenomenon: a quasiconvex optimization approach
    • Authors: Yuhai Hu; Boris Defourny
      Abstract: This paper is concerned with grid-level battery storage operations, taking battery aging into consideration. Battery operations under price uncertainty are modeled as a Markov Decision Process with expected cumulated discounted rewards. The structure of the optimal policy is studied. An algorithm that takes advantage of the problem structure and works directly on the continuous state space is developed to maximize the objective over the life of the battery. The algorithm determines an optimal policy by solving a sequence of quasiconvex problems indexed by a battery-life state. Computational results are presented to compare the proposed approach to a standard dynamic programming method, and to evaluate the impact of refinements in the battery model. Error bounds for the proposed algorithm are established to demonstrate its accuracy.

  • Novel formulations and VNS-based heuristics for single and multiple
           allocation p -hub maximal covering problems
    • Authors: Olivera Janković; Stefan Mišković; Zorica Stanimirović; Raca Todosijević
      Abstract: This paper deals with uncapacitated single and multiple allocation p-hub maximal covering problems (USApHMCP and UMApHMCP) with binary and partial covering criteria. We present new mixed-integer programming formulations of the considered problems, which are valid for both binary and partial coverage cases. The efficiency of the proposed formulations is evaluated through computational experiments on smaller-size instances, and compared with the state-of-the art models from the literature. The obtained results indicate that the new UMApHMCP formulation outperforms the existing one for both coverage criteria in the sense of solutions’ quality and running times. In order to solve instances of larger problem dimension, we develop two heuristic methods based on variable neighborhood search: general VNS (GVNS) for USApHMCP and basic VNS (BVNS) for UMApHMCP. The proposed GVNS and BVNS involve the same shaking procedure in order to hopefully escape local minima traps, while local search phases in GVNS and BVNS use different neighborhood structures in accordance with applied allocation schemes. Computational experiments conducted on smaller-size instances showed that both GVNS and BVNS almost instantly reach all known optimal solutions. In addition, the proposed GVNS and BVNS showed to be very efficient when solving large and large-scale hub instances with up to 1000 nodes, which were not previously considered as test instances for the considered problems. Both GVNS and BVNS provided best solutions on challenging USApHMCP and UMApHMCP instances for both coverage cases in short running times, which indicates their potential to be applied to similar problems.

  • A survey of the standard location-routing problem
    • Authors: Michael Schneider; Michael Drexl
      Abstract: In this paper, we define the standard LRP as a deterministic, static, discrete, single-echelon, single-objective location-routing problem in which each customer (vertex) must be visited exactly once for the delivery of a good from a facility, and in which no inventory decisions are relevant. We review the literature on the standard LRP published since the survey by Nagy and Salhi appeared in 2006. We provide concise paper excerpts that convey the central ideas of each work, discuss recent developments in the field, provide a numerical comparison of the most successful heuristic algorithms, and list promising topics for further research.

  • Partially concurrent open shop scheduling with integral preemptions
    • Authors: Hagai Ilani; Elad Shufan; Tal Grinshpoun
      Abstract: Partially-concurrent open shop scheduling (PCOSS) was recently introduced as a common generalization of the well-known open shop scheduling model and the concurrent open shop scheduling model. PCOSS was shown to be NP-hard even when there is only one machine and all operations have unit processing time. In the present paper we study PCOSS problems with integral processing times that allow preemptions at integral time points. A special and simple subclass of the problems at focus is that of unit processing times, which is considered separately. For these two cases a schedule is related to the colouring of a graph called the conflict graph, which represents the operations that cannot be performed concurrently. This enables us to extract insights and solutions from the well-studied field of graph colouring and apply them to the recently introduced PCOSS model. We then focus on two special cases of the problem—the case where the conflict graph is perfect, and the case of uniform PCOSS, in which all the jobs, including their conflicts, are identical. The development of the PCOSS model was motivated from a real-life timetabling project of assigning technicians to a fleet of airplanes. The latter case of uniform PCOSS correlates to instances in which the fleet of airplanes is homogeneous.
