  • A multi-heuristic approach for solving the pre-marshalling problem
    • Authors: Raka Jovanovic; Milan Tuba; Stefan Voß
      Pages: 1 - 28
      Abstract: Minimizing the number of reshuffling operations at maritime container terminals incorporates the pre-marshalling problem (PMP) as an important problem. Based on an analysis of existing solution approaches we develop new heuristics utilizing specific properties of problem instances of the PMP. We show that the heuristic performance is highly dependent on these properties. We introduce a new method that exploits a greedy heuristic of four stages, where for each of these stages several different heuristics may be applied. Instead of using randomization to improve the performance of the heuristic, we repetitively generate a number of solutions by using a combination of different heuristics for each stage. In doing so, only a small number of solutions is generated for which we intend that they do not have undesirable properties, contrary to the case when simple randomization is used. Our experiments show that such a deterministic algorithm significantly outperforms the original nondeterministic method. The improvement is twofold, both in the quality of found solutions, and in the computational effort.

  • A Benders’ decomposition algorithm for optimizing distribution of
           perishable products considering postharvest biological behavior in
           agri-food supply chain: a case study of tomato
    • Authors: V. R. Ghezavati; S. Hooshyar; R. Tavakkoli-Moghaddam
      Pages: 29 - 54
      Abstract: This paper presents a periodical planning mathematical model for distribution of fresh agri-food (a case study of tomato) after qualitative segregating. The main objective of the model is to maximize the profit of a distributor that has relative control on logistics decisions associated with distribution of fresh products in a agri-food supply chain. In a real world, there are some differences between suitable qualities of each customer and thus, fair pricing is determined by their level of satisfaction. Simultaneously, this model takes into account freshness and ripeness as for the food grade. For estimation of the ripeness, a formulation is used that is related to postharvest biological behavior of the fresh crops. In turn, quality loss functions for quantification of degrading are designed to accommodate fair pricing. In addition, potential warehouses are considered in this model to achieve suitable maturity and service level. This paper presents a mixed integer programming model according to the problem descriptions. Since the model is hard to be solved for large scale problems, a primal decomposition solution procedure is proposed based on Benders’ decomposition method. Meanwhile, performance of the proposed solution method will be evaluated through some test problems. Finally, the model is validated through decision making for a domestic distributor of fresh tomato in Iran.

  • A heuristic framework on a common generalization of the Vehicle Routing
           Problem and the Linear Ordering Problem
    • Authors: Zoltán Blázsik; Zoltán Imre Fajfrik
      Pages: 55 - 70
      Abstract: A framework for bounding and approximating the solution of a newly formulated problem, the Vehicle Routing Problem with Internal Transports (VRPIT) Blázsik et al. (Pure Math Appl 17: 229–239, 2006), is presented. VRPIT is a common generalization of two well-known NP-hard problems, the Vehicle Routing Problem (VRP) Laporte (Eur J Op Res 59(3):345–358, 1992) and the Linear Ordering Problem (LOP) Schiavinotto and Stützle (J Math Model Algorithms 3(4):367–402, 2004). This generalization was motivated by the following situation: Consider VRP with the additional opportunity that each vehicle may make internal transports via short tours during its overall tour. In order to obtain the optimal income, we want to reduce the cost of small tours in relation to the profit that can be achieved by the corresponding internal transports with unit capacities. The structure of feasible solutions can be viewed as cycles of a permutation. The objective function is the difference between the profit from internal transports and the cost of the short tours. Although VRPIT is coming from the generalization of VRT and LOP, other equally hard problems can be reduced to it, as well.

  • Operational effects of service level variations for the dial-a-ride
           problem
    • Authors: Yves Molenbruch; Kris Braekers; An Caris
      Pages: 71 - 90
      Abstract: The dial-a-ride problem consists of designing a number of minimum-cost vehicle routes in a system of demand-dependent, collective people transportation. Quality is ensured by taking into account service level requirements. However, little research has been conducted into the effect of service level variations on operational costs incurred by service providers. This study investigates the evolution of operational costs for 78 combinations of two service level parameters, being the maximum deviation from a user’s preference time and the relative maximum exceedance of a user’s direct ride time. A distinction is made between various operating circumstances, including the size of the service provider, the traffic conditions in the service area and the heterogeneity of the customers. The resulting tradeoffs between quality and costs should encourage service providers to make informed decisions regarding potential changes in the service level they offer. The sensitivity analysis in this paper is performed on well-known benchmark data from literature and applies a state-of-the-art deterministic annealing metaheuristic to compute operational costs.

  • Efficiency analysis of European Freight Villages: three peers for
           benchmarking
    • Authors: Congcong Yang; Alfred Taudes; Guozhi Dong
      Pages: 91 - 122
      Abstract: Measuring the efficiency of Freight Villages (FVs) has important implications for logistics companies and other related companies as well as governments. In this paper we apply data envelopment analysis (DEA) to measure the efficiency of European FVs in a purely data-driven way, incorporating the nature of FVs as complex operations that use multiple inputs and produce several outputs. We employ several DEA models and perform a complete sensitivity analysis of the appropriateness of the chosen input and output variables, and an assessment of the robustness of the efficiency score. It turns out that about half of the 20 FVs analyzed are inefficient, with utilization of the intermodal area, warehouse capacity and level of goods handling being the most important areas of improvement. While we find no significant differences in efficiency between FVs of different sizes and in different countries, it turns out that the FVs Eurocentre Toulouse, Interporto Quadrante Europa and GVZ Nürnberg constitute more than 90 % of the benchmark share.

  • Master disassembly scheduling in a remanufacturing system with stochastic
           routings
    • Authors: Muris Lage Junior; Moacir Godinho Filho
      Pages: 123 - 138
      Abstract: Remanufacturing is an important source of sustainable development. Remanufactured products have proven to be high quality and low cost. Due to their unique characteristics, remanufacturing processes have many differences compared to manufacturing processes. These characteristics, which make remanufacturing complex, require good performance from Production Planning and Control (PPC) activities. The goal of the paper is to propose a mathematical model for disassembly master production scheduling considering stochastic routings in the remanufacturing environment. The proposed model is based on stochastic dynamic programming and it is applied to a real case of automotive clutch remanufacturing. The results contribute to the development of theory and practice by filling a gap in knowledge of the use of PPC systems, developing a mathematical method that can be easily implemented in a spreadsheet. The findings also show some decisions that are counterintuitive. For example, in some situations disassemble more products than necessary to meet the demand can result in a lower expected total cost.

  • A note on minimizing the sum of squares of machine completion times on two

    • Authors: Rico Walter
      Pages: 139 - 144
      Abstract: In this short note, we address the coherence between minimizing the sum of squares of machine completion times and minimizing makespan on two identical parallel machines. We show equivalence of the two objectives and identify interesting and useful relations which allow us to transfer worst-case ratios of approximation algorithms from one problem to the other.

  • On the criterion vectors of lines of portfolio selection with multiple
           quadratic and multiple linear objectives
    • Authors: Yue Qi
      Pages: 145 - 158
      Abstract: As the research for portfolio selection evolves, traditional models and models with one quadratic objective and multiple linear objectives are being solved. In this paper, I propose models with multiple quadratic and multiple linear objectives. Due to the difficulty involved, I study the new models by lines in decision space, analyze the criterion vectors of the lines by projection, and approximate the nondominated sets by the criterion vectors. As an illustration, I extend Merton’s portfolio selection model, propose algorithms to approximate the nondominated sets by the criterion vectors of portfolios with cardinality 3 and then K, and demonstrate the number of the criterion vectors.

  • Product innovation with lumpy investment
    • Authors: M. Chahim; D. Grass; R. F. Hartl; P. M. Kort
      Pages: 159 - 182
      Abstract: The paper provides a framework that enables us to analyze the important topic of capital accumulation under technological progress. We describe an algorithm to solve Impulse Control problems, based on a (multipoint) boundary value problem approach. Investment takes place in lumps and we determine the optimal timing of technology adoptions as well as the size of the corresponding investments. Our numerical approach led to some guidelines for new technology investments. First, we find that investments are larger and occur in a later stadium when more of the old capital stock needs to be scrapped. Moreover, we obtain that the size of the firm’s investments increase when the technology produces more profitable products. We see that the firm in the beginning of the planning period adopts new technologies faster as time proceeds, but later on the opposite happens. Furthermore, we find that the firm does not invest such that marginal profit is zero, but instead marginal profit is negative.

  • A dynamic programming model for effect of worker’s type on wage
           arrears
    • Authors: Wenjing Liu; Ke Liu; Lulu Yang
      Pages: 183 - 201
      Abstract: We analyze how wage arrears are affected by the worker’s type (in this paper, the worker’s type means the worker’s attitude to wage arrears). Wage arrears cause workers’ negative emotion which may lead to serious social problem and the government may intervene. In this paper, we model the process of wage arrears as a Markov decision process in which the firm is the decision maker. We develop an optimal solution approach under the assumption that the worker’s negative emotion threshold (The worker’s negative emotion increases monotonically with increasing back pay. Once the cumulative back pay exceeds a particular value, the worker will take legal actions and the government will intervene. We define the particular value as the worker’s negative emotion threshold.) is normally distributed and provide insights into how wage arrears vary with the worker’s type and the government intervention. We propose the optimal government intervention which stops wage arrears and does not disturb the normal order of the market economy. We show that the intervention depends on the worker’s type and the results imply that the government intervention should be adjusted dynamically according to different regions, industrial sectors and time periods.

  • Management science in the era of smart consumer products: challenges and
           research perspectives
    • Authors: Herbert Dawid; Reinhold Decker; Thomas Hermann; Hermann Jahnke; Wilhelm Klat; Rolf König; Christian Stummer
      Pages: 203 - 230
      Abstract: Smart products not only provide novel functionalities, but also may establish new business models, markets, or distribution channels, strengthen relationships with consumers, and/or add smart remote services. While many technical obstacles of such products have already been overcome, the broad market dissemination of smart products still poses some vital managerial challenges for decision makers. In this paper, we outline the technical potential and future trends of smart consumer products, discuss economic challenges in four scopes, namely, preference-based new product development, market analysis, supply chain design, and industry development, and, in particular, we highlight research perspectives for management science in this promising field.

  • Generating subtour elimination constraints for the TSP from pure integer
           solutions
    • Authors: Ulrich Pferschy; Rostislav Staněk
      Pages: 231 - 260
      Abstract: The traveling salesman problem (TSP) is one of the most prominent combinatorial optimization problems. Given a complete graph \(G = (V, E)\) and non-negative distances d for every edge, the TSP asks for a shortest tour through all vertices with respect to the distances d. The method of choice for solving the TSP to optimality is a branch and cut approach. Usually the integrality constraints are relaxed first and all separation processes to identify violated inequalities are done on fractional solutions. In our approach we try to exploit the impressive performance of current ILP-solvers and work only with integer solutions without ever interfering with fractional solutions. We stick to a very simple ILP-model and relax the subtour elimination constraints only. The resulting problem is solved to integer optimality, violated constraints (which are trivial to find) are added and the process is repeated until a feasible solution is found. In order to speed up the algorithm we pursue several attempts to find as many relevant subtours as possible. These attempts are based on the clustering of vertices with additional insights gained from empirical observations and random graph theory. Computational results are performed on test instances taken from the TSPLIB95 and on random Euclidean graphs.

  • Order Batching and Picker Routing in manual order picking systems: the
           benefits of integrated routing
    • Authors: A. Scholz; G. Wäscher
      Abstract: Order Batching and Picker Routing Problems arise in warehouses when items specified by customer orders have to be retrieved from their storage locations. The Order Batching Problem includes the grouping of a given set of customer orders into feasible picking orders such that the total length of all picker tours is minimized. In order to calculate the length of a picker tour, the sequence has to be determined according to which the items contained in the picking order will be picked. This problem is known as the Picker Routing Problem. Although quite sophisticated heuristics and even efficient exact solution approaches exist to the Picker Routing Problem in warehouse with up to two blocks, the routing problem does not get much attention when dealing with the Order Batching Problem. Instead, the order pickers are assumed to follow a certain, simple routing strategy when making their ways through the warehouse. The advantage of this approach can be seen in the fact that—in particular for single-block warehouse layouts—the corresponding picker tours are very straightforward and can be memorized easily by the order pickers. This advantage diminishes, however, when more complex, multi-block layouts have to be dealt with. Furthermore, in such case, the approach may result in picker tours which are far from optimal. For multi-block layouts, we integrate different routing algorithms into an iterated local search approach for the batching in order to demonstrate what the benefits are from solving the Order Batching and the Picker Routing Problem in a more integrated way. By means of numerical experiments it is shown that paying more attention to the Picker Routing Problem results in a substantial improvement of the solution quality without increasing computing times.

  • Treating measurement uncertainty in industrial conformity control
    • Authors: Zsolt T. Kosztyán; Csaba Hegedűs; Attila Katona
      Abstract: Every conformity control method based on measurements is subject to uncertainty, which distorts the decision. In the traditional conformity control approaches, this uncertainty is an inherent part of the deviation of the observed characteristic; however, the distribution of the real product characteristic may differ from the distribution of measurement uncertainty, which obscures the real conformity or nonconformity. The specification and consideration of this uncertainty are particularly necessary if it is high and/or the consequences associated with the decision errors are severe. This paper studies the effects of the cost structure associated with the decision outcomes and the skewness and kurtosis of the measurement uncertainty distribution. The proposed method can specify when and how the measurement uncertainty should be taken into account to increase the expected profit associated with the decision.

  • Extending the multi-criteria decision making method DEX with numeric
           attributes, value distributions and relational models
    • Authors: Nejc Trdin; Marko Bohanec
      Abstract: DEX is a qualitative multi-criteria decision analysis method. The method supports decision makers in making complex decisions based on multiple, possibly conflicting, attributes. The attributes in DEX have qualitative value scales and are structured hierarchically. The hierarchical topology allows for decomposition of the decision problem into simpler sub-problems. In DEX, alternatives are described with qualitative values, taken from the scales of corresponding input attributes in the hierarchy. The evaluation of alternatives is performed in a bottom-up way, utilizing aggregation functions, which are defined for every aggregated attribute in the form of decision rules. DEX has been used in numerous practical applications—from everyday decision problems to solving decision problems in the financial and ecological domains. Based on experience, we identified the need for three major methodological extensions to DEX: introducing numeric attributes, the probabilistic and fuzzy aggregation of values and relational models. These extensions were proposed by users of the existing method and by the new demands of complex decision problems, which require advanced decision making approaches. In this paper, we introduce these three extensions by describing the extensions formally, justifying their contributions to the decision making process and illustrating them on a didactic example, which is followed throughout the paper.

  • One-dimensional stock cutting: optimization of usable leftovers in
           consecutive orders
    • Authors: Luka Tomat; Mirko Gradišar
      Abstract: This paper deals with usable leftovers (UL) in one-dimensional stock cutting in consecutive orders. UL are leftovers longer than a certain threshold and are returned to stock in order to be used in future orders. Shorter leftovers are treated as trim-loss. If UL are being used at a slower pace, than they are being generated for a longer period of time, excessive growth of UL in stock can appear. This is not acceptable due to higher costs of manipulations and warehousing. However, a certain amount of UL in stock is desirable because it contributes to greater variety of stock lengths, which in general results in lower trim-loss. The method solves the problem of how to calculate the near optimal amount of UL in stock and how to control the stock. The proposed method is tested by using a computer simulation in which UL from previous orders are used in the next ones instead of being randomly generated. The computational results indicate that trim-loss in consecutive orders is reduced, and excessive growth of UL in stock is prevented.

  • Stochastic sensitivity analysis of concentration measures
    • Authors: Martin Bod’a
      Abstract: The paper extends the traditional approach to measuring market concentration by embracing an element of stochasticity that should reflect the analyst’s uncertainty associated with the future development regarding concentration on the market. Whereas conventional practice relies on deterministic assessments of a market concentration measure with the use of current market shares, this says nothing about possible changes that may happen even in a near future. The paper proposes to model the analyst’s beliefs by dint of a suitable joint probability distribution for future market shares and demonstrates how this analytic framework may be employed for regulatory purposes. A total of four candidates for the joint probability distribution of market shares are considered—the Dirichlet distribution, the conditional normal distribution, the Gaussian copula with conditional beta marginals and the predictive distribution arising from the market share attraction model—and it is shown how their hyperparameters can be elicited so that a minimum burden is placed on the analyst. The proposed procedure for stochastic sensitivity analysis of concentration measures is demonstrated in a case study oriented on the Slovak banking sector.

  • Multi-objective two-stage grey transportation problem using utility
           function with goals
    • Authors: Sankar Kumar Roy; Gurupada Maity; Gerhard-Wilhelm Weber
      Abstract: Multi-Objective Goal Programming is applied to solve problems in many application areas of real-life decision making problems. We formulate the mathematical model of Two-Stage Multi-Objective Transportation Problem (MOTP) where we design the feasibility space based on the selection of goal values. Considering the uncertainty in real-life situations, we incorporate grey parameters for supply and demands into the Two-Stage MOTP, and a procedure is applied to reduce the grey numbers into real numbers. Thereafter, we present a solution procedure to the proposed problem by introducing an algorithm and using the approach of Revised Multi-Choice Goal Programming. In the proposed algorithm, we introduce a utility function for selecting the goals of the objective functions. A numerical example is encountered to justify the reality and feasibility of our proposed study. Finally, the paper ends with a conclusion and an outlook to future investigations of the study.

  • Frequency assignment problem in networks with limited spectrum
    • Authors: Zehui Shao; Aleksander Vesel; Jin Xu
      Abstract: The frequency assignment problem (FAP) asks for assigning frequencies (channels) in a wireless network from the available radio spectrum to the transceivers of the network. One of the graph theoretical models of FAP is the L(3, 2, 1)-labeling of a graph, which is an abstraction of assigning integer frequencies to radio transceivers such that (i) transceivers that are one unit of distance apart receive frequencies that differ by at least three, (ii) transceivers that are two units of distance apart receive frequencies that differ by at least two, and (iii) transceivers that are three units of distance apart receive frequencies that differ by at least one. The relaxation of the L(3, 2, 1)-labeling called the (s, t, r)-relaxed k-L(3, 2, 1)-labeling is proposed in this paper. This concept is a generalization of the (s, t)-relaxed k-L(2, 1)-labeling (Lin in J Comb Optim 2016, doi:10.1007/s10878-014-9746-9). Basic properties of (s, t, r)-relaxed k-L(3, 2, 1)-labeling are discussed and optimal (s, t, r)-relaxed k-L(3, 2, 1)-labelings for paths and some cycles as well as for the hexagonal lattice and the square lattice are determined.
