  • Using forward Monte-Carlo simulation for the valuation of American barrier
    • Authors: Daniel Wei-Chung Miao; Yung-Hsin Lee; Jr-Yan Wang
      Abstract: Abstract This paper extends the forward Monte-Carlo methods, which have been developed for the basic types of American options, to the valuation of American barrier options. The main advantage of these methods is that they do not require backward induction, the most time-consuming and memory-intensive step in the simulation approach to American options pricing. For these methods to work, we need to define the so-called pseudo critical prices which are used to determine whether early exercise should happen. In this study, we define a new and more flexible version of the pseudo critical prices which can be conveniently extended to all fourteen types of American barrier options. These pseudo critical prices are shown to satisfy the criteria of a sufficient indicator which guarantees the effectiveness of the proposed methods. A series of numerical experiments are provided to compare the performance between the forward and backward Monte-Carlo methods and demonstrate the computational advantages of the forward methods.

  • A multiproduct single machine economic production quantity (EPQ) inventory
           model with discrete delivery order, joint production policy and budget
    • Authors: Amir Hossein Nobil; Amir Hosein Afshar Sedigh; Leopoldo Eduardo Cárdenas-Barrón
      Abstract: Abstract This paper develops a multiproduct economic production quantity inventory model for a vendor–buyer system in which several products are manufactured on a single machine. The vendor delivers the products to customer in small batches. The number of orders must be a discrete value. Moreover, benefitting from a just-in-time policy, the buyer decides the size of the delivered batches. Due to the fact that several products are manufactured on one machine, this makes that the production capacity be considered as a constraint. The aim of this study is to determine the optimal cycle length and the number of delivered batches for each product so that the total inventory cost is minimized. The problem under study is modeled as a mixed integer nonlinear programing problem considering maximum number of orders, capacity and budget constraints. Three different methods are developed and employed to solve this problem: an exact method, a heuristic algorithm and a hybrid genetic algorithm. Based on the results, the three algorithms have near efficiency with different running times. The results shows that the heuristic algorithm obtains a good solution in a short time and the hybrid genetic algorithm finds solutions with higher quality in an acceptable time. Finally, a sensitivity analysis is done to evaluate the effect of changes in the parameters of problem.

  • Pricing derivatives on multiple assets: recombining multinomial trees
           based on Pascal’s simplex
    • Authors: Dirk Sierag; Bernard Hanzon
      Abstract: Abstract In this paper a direct generalisation of the recombining binomial tree model by Cox et al. (J Financ Econ 7:229–263, 1979) based on the Pascal’s simplex is constructed. This discrete model can be used to approximate the prices of derivatives on multiple assets in a Black–Scholes market environment. The generalisation keeps most aspects of the binomial model intact, of which the following are the most important: The direct link to the Pascal’s simplex (which specialises to Pascal’s triangle in the binomial case); the matching of moments of the (log-transformed) process; convergence to the correct option prices both for European and American options, when the time step length goes to zero and the completeness of the model, at least for sufficiently small time step. The goal of this paper is to present basic theoretical aspects of this approach. However, we also illustrate the approach by a number of example calculations. Further possible developments of this approach are discussed in a final section.

  • Semi-supervised generalized eigenvalues classification
    • Authors: Marco Viola; Mara Sangiovanni; Gerardo Toraldo; Mario R. Guarracino
      Abstract: Abstract Supervised classification is one of the most powerful techniques to analyze data, when a-priori information is available on the membership of data samples to classes. Since the labeling process can be both expensive and time-consuming, it is interesting to investigate semi-supervised algorithms that can produce classification models taking advantage of unlabeled samples. In this paper we propose LapReGEC, a novel technique that introduces a Laplacian regularization term in a generalized eigenvalue classifier. As a result, we produce models that are both accurate and parsimonious in terms of needed labeled data. We empirically prove that the obtained classifier well compares with other techniques, using as little as 5% of labeled points to compute the models.

  • Network DEA-based biobjective optimization of product flows in a supply
    • Authors: Sebastian Lozano; Belarmino Adenso-Diaz
      Abstract: Abstract This paper deals with planning the product flows along a supply chain (SC) in which there are product losses in the nodes and in the arcs. Given the demand by each retailer, appropriate quantities to be procured from the different suppliers must be decided and the routing of the product along the SC must be determined. Care must be taken because, due to losses, the amount of product that will be finally available at the retailers is lower than the amount of product procured. The objective is twofold: minimizing total costs and minimizing product losses. The proposed approach leverages the existence of data on the flows in previous periods. With those observed flows, a Network Data Envelopment Analysis technology is inferred which allows the computing of any feasible operating point. The resulting biobjective optimization problem can be solved using the weighted Tchebycheff method.

  • Carbon emission reduction and pricing policies of a supply chain
           considering reciprocal preferences in cap-and-trade system
    • Authors: Liangjie Xia; Tingting Guo; Juanjuan Qin; Xiaohang Yue; Ning Zhu
      Abstract: Abstract The traditional self-interest hypothesis is far from perfect. Social preference has a significant impact on every firm’s decision making. This paper incorporates reciprocal preferences and consumers’ low-carbon awareness (CLA) into the dyadic supply chain in which a single manufacturer plays a Stackelberg-like game with a single retailer. This research intends to investigate how reciprocity and CLA may affect the decisions and performances of the supply chain members and the system’s efficiency. In this study, the following two scenarios are discussed: (1) both the manufacturer and the retailer have no reciprocal preferences and (2) both of them have reciprocal preferences. We derive equilibriums under both scenarios and present a numerical analysis. We demonstrate that reciprocal preferences and CLA significantly affect the equilibrium and firms’ profits and utilities. First, the optimal retail price increases with CLA, while it decreases with the reciprocity of the retailer and the manufacturer; the optimal wholesale price increases with CLA and the retailer’s reciprocity, while it decreases with the manufacturer’s reciprocity. The optimal emission reduction level increases with CLA and the reciprocity of both the manufacturer and the retailer. Second, the optimal profits of the participants and the supply chain increase with CLA, the participants’ optimal profits are concave in their own reciprocity and increase with their co-operators’ reciprocity. Third, the participants’ optimal utilities increase with CLA and their reciprocity. Finally, the supply chain efficiency increases with the participants’ reciprocity, while the efficiency decreases with CLA.

  • Dispatching algorithm for production programming of flexible job-shop
           systems in the smart factory industry
    • Authors: Miguel A. Ortíz; Leidy E. Betancourt; Kevin Parra Negrete; Fabio De Felice; Antonella Petrillo
      Abstract: Abstract In today highly competitive and globalized markets, an efficient use of production resources is necessary for manufacturing enterprises. In this research, the problem of scheduling and sequencing of manufacturing system is presented. A flexible job shop problem sequencing problem is analyzed in detail. After formulating this problem mathematically, a new model is proposed. This problem is not only theoretically interesting, but also practically relevant. An illustrative example is also conducted to demonstrate the applicability of the proposed model.

  • Computational experiment of critical event tabu search for the general
           integer multidimensional knapsack problem
    • Authors: Bahram Alidaee; Vijay P. Ramalingam; Haibo Wang; Bryan Kethley
      Abstract: Abstract In this paper, we propose a critical event tabu search meta-heuristic for the general integer multidimensional knapsack problem (GMDKP). Variations of GMDKP have enormous applications, and often occur as a sub-problem of more general combinatorial problems. For the special case of binary multidimensional knapsack problems (BMDKP) there are variety of heuristics, mostly sophisticated meta-heuristics, which provides good solutions to the problem. However, to date there is no method that can provide reasonable solutions to realistic size GMDKP. To the best of our knowledge there are only three heuristics published in the literature for GMDKP, and all three are simple greedy heuristics. There is no meta-heuristic available that effectively provides good solutions for large-scale GMDKP. One successful meta-heuristic that has proven to be highly effective in solving combinatorial optimization is a variation of tabu search known as the critical event tabu search (CETS). CETS was originally proposed for the BMDKP with considerable success afterwards. In CETS, clever use of surrogate programming is embedded as choice rules to obtain high quality solutions. The main purpose of this paper is to design the meta-heuristic CETS for the GMDKP using variety of different surrogate choice rules. Extensive computational experiment for large-scale problems are presented. Our procedures open the door for further applications of meta-heuristics to general integer programs.

  • Complexity, bounds and dynamic programming algorithms for single track
           train scheduling
    • Authors: Jonas Harbering; Abhiram Ranade; Marie Schmidt; Oliver Sinnen
      Abstract: Abstract In this work we consider the single track train scheduling problem. The problem consists of scheduling a set of trains from opposite sides along a single track. The track has intermediate stations and the trains are only allowed to pass each other at those stations. Traversal times of the trains on the blocks between the stations only depend on the block lengths but not on the train. This problem is a special case of minimizing the makespan in job shop scheduling with two counter routes and no preemption. We develop a lower bound on the makespan of the train scheduling problem which provides us with an easy solution method in some special cases. Additionally, we prove that for a fixed number of blocks the problem can be solved in pseudo-polynomial time.

  • Optimal inventory policies for deteriorating items with trapezoidal-type
           demand patterns and maximum lifetimes under upstream and downstream trade
    • Authors: Jiang Wu; Jinn-Tsair Teng; Konstantina Skouri
      Abstract: Abstract In general, the demand rate moving through a product life cycle can be reasonably depicted by a trapezoidal-type pattern: it initially increases during the introduction and growth phases, then remains reasonably constant in the maturity phase, and finally decreases in the decline phase. It is evident that perishable products deteriorate continuously over time and can not be sold after its maximum lifetime. Thus, the deterioration rate of a product is increasing with time and closely related to its maximum lifetime. Furthermore, it has been hard to obtain loans from banks since the global financial meltdown in 2008. Hence, over 80% of firms in the United Kingdom and the United States sell their products on various short-term, interest-free loans (i.e., trade credit) to customers. To incorporate those important facts, we develop an inventory model by (1) assuming the demand pattern is trapezoidal, (2) extending the deterioration rate to 100% as its maximum lifetime is approaching, (3) using discounted cash-flow analysis to calculate all relevant costs considering the effects of upstream and downstream trade credits, and (4) including the costly purchase cost into the total cost, which is omitted in previous studies. Then, the order quantity that maximizes the present value of the profit is uniquely determined. Finally, through numerical examples, managerial insights are provided.

  • Efficient extensions of communication values
    • Authors: Sylvain Béal; André Casajus; Frank Huettner
      Abstract: Abstract We study values for transferable utility games enriched by a communication graph. The most well-known such values are component-efficient and characterized by some deletion link property. We study efficient extensions of such values: for a given component-efficient value, we look for a value that (i) satisfies efficiency, (ii) satisfies the link-deletion property underlying the original component-efficient value, and (iii) coincides with the original component-efficient value whenever the underlying graph is connected. Béal et al. (Soc Choice Welf 45:819–827, 2015) prove that the Myerson value (Myerson in Math Oper Res 2:225–229, 1977) admits a unique efficient extension, which has been introduced by van den Brink et al. (Econ Lett 117:786–789, 2012). We pursue this line of research by showing that the average tree solution (Herings et al. in Games Econ Behav 62:77–92, 2008) and the compensation solution (Béal et al. in Int J Game Theory 41:157–178, 2012b) admit similar unique efficient extensions, and that there exists no efficient extension of the position value (Meessen in Communication games, 1988; Borm et al. in SIAM J Discrete Math 5:305–320, 1992). As byproducts, we obtain new characterizations of the average tree solution and the compensation solution, and of their efficient extensions.

  • Perfect edge domination: hard and solvable cases
    • Authors: Min Chih Lin; Vadim Lozin; Veronica A. Moyano; Jayme L. Szwarcfiter
      Abstract: Abstract Let G be an undirected graph. An edge of G dominates itself and all edges adjacent to it. A subset \(E'\) of edges of G is an edge dominating set of G, if every edge of the graph is dominated by some edge of \(E'\) . We say that \(E'\) is a perfect edge dominating set of G, if every edge not in \(E'\) is dominated by exactly one edge of \(E'\) . The perfect edge dominating problem is to determine a least cardinality perfect edge dominating set of G. For this problem, we describe two NP-completeness proofs, for the classes of claw-free graphs of degree at most 3, and for bounded degree graphs, of maximum degree at most \(d \ge 3\) and large girth. In contrast, we prove that the problem admits an O(n) time solution, for cubic claw-free graphs. In addition, we prove a complexity dichotomy theorem for the perfect edge domination problem, based on the results described in the paper. Finally, we describe a linear time algorithm for finding a minimum weight perfect edge dominating set of a \(P_5\) -free graph. The algorithm is robust, in the sense that, given an arbitrary graph G, either it computes a minimum weight perfect edge dominating set of G, or it exhibits an induced subgraph of G, isomorphic to a \(P_5\) .

  • A novel DEA model based on uncertainty theory
    • Authors: Zahra Mohmmad Nejad; Alireza Ghaffari-Hadigheh
      Abstract: Abstract In deterministic DEA models, precise values are assigned to input and output data while they are intrinsically subjected to some degree of uncertainty. Most studies in this area are based on the assumption that inputs and outputs are equipped with some pre-known knowledge that enables one to use probability theory or fuzzy theory. In the lack of such data, one has to trust on the experts’ opinions, which can be considered as a sort of uncertainty. In this situation, the axiomatic approach of uncertainty theory initiated by Liu (Uncertainty theory. Berlin: Springer, 2007) could be an adequate powerful tool. Applying this theory, Wen et al. (J Appl Math, 2014; Soft Comput 1987–1996, 2015) suggested an uncertain DEA model while it has the disadvantage of pessimism. In this paper, we introduce another uncertain DEA model with the objective of acquiring the highest belief degree that the evaluated DMU is efficient. We also apply this model in ranking of the evaluated DMUs. Implementation of the model on different illustrative examples reveals that the ranks of DMUs are almost-stable in our model. This observation states that the rank of a DMU may roughly alternate with respect to the variation of minimum belief degrees. Our proposed model also compensates the rather optimistic point of view in the Wen et al. model that identifies all DMUs as efficient for higher belief degrees.

  • Swift trust and commitment: The missing links for humanitarian supply
           chain coordination'
    • Authors: Rameshwar Dubey; Nezih Altay; Constantin Blome
      Abstract: Abstract Coordination among actors in a humanitarian relief supply chain decides whether a relief operation can be or successful or not. In humanitarian supply chains, due to the urgency and importance of the situation combined with scarce resources, actors have to coordinate and trust each other in order to achieve joint goals. This paper investigated empirically the role of swift trust as mediating variable for achieving supply chain coordination. Based on commitment-trust theory we explore enablers of swift-trust and how swift trust translates into coordination through commitment. Based on a path analytic model we test data from the National Disaster Management Authority of India. Our study is the first testing commitment-trust theory in the humanitarian context, highlighting the importance of swift trust and commitment for much thought after coordination. Furthermore, the study shows that information sharing and behavioral uncertainty reduction act as enablers for swift trust. The study findings offer practical guidance and suggest that swift trust is a missing link for the success of humanitarian supply chains.

  • A column generation approach and new bounds for the car sequencing problem
    • Authors: Eivind Jahren; Roberto Asín Achá
      Abstract: Abstract The subject of the 2005 ROADEF challenge was a variation of the car scheduling problem based on the needs of the Renaultfactories. In this paper we revisit this problem to investigate how further contributions can be made in order to close the gap between exact and heuristic methods that exists for this problem. For the benchmark set used in the final round of the competition we report new lower bounds for 7 out of the 19 instances by using an improved ILP formulation of the problem. We also present a new column generation based exact method for solving the ILP problem which outperforms branch-and-bound in obtaining upper bounds for these problems.

  • DEA cross-efficiency evaluation and ranking method based on interval data
    • Authors: Yu Yu; Weiwei Zhu; Qian Zhang
      Abstract: Abstract Data envelopment analysis (DEA) is an important method of efficiency evaluation. Cross-efficiency evaluation is one of the main aspects of research in the field of DEA that has been applied in various fields. In the traditional cross-efficiency evaluation model, the variable data of decision-making units is exact. Dynamic information is frequently unable to reflect the whole characteristic when determining the exact data. In this study, we select interval data to represent the dynamic information of some variables in the evaluation process. We then build a solution method based on interval efficiency and DEA cross-efficiency. This method retains the reflection of interval data on uncertain variable properties. Finally, the stochastic multi-criteria acceptability analysis 2 (SMAA2) is introduced to solve the whole sequence problem of interval efficiency. We present a case study from a set of 19 reservoir dams suffered from Wenchuan earthquake in Luojiang County, Sichuan Province to demonstrate the applicability of the proposed model.

  • Continuity of equilibria for two-person zero-sum games with noncompact
           action sets and unbounded payoffs
    • Authors: Eugene A. Feinberg; Pavlo O. Kasyanov; Michael Z. Zgurovsky
      Abstract: Abstract This paper extends Berge’s maximum theorem for possibly noncompact action sets and unbounded cost functions to minimax problems and studies applications of these extensions to two-player zero-sum games with possibly noncompact action sets and unbounded payoffs. For games with perfect information, also known under the name of turn-based games, this paper establishes continuity properties of value functions and solution multifunctions. For games with simultaneous moves, it provides results on the existence of lopsided values (the values in the asymmetric form) and solutions. This paper also establishes continuity properties of the lopsided values and solution multifunctions.

  • The Shapley value in the Knaster gain game
    • Authors: Federica Briata; Andrea Dall’Aglio; Marco Dall’Aglio; Vito Fragnelli
      Abstract: Abstract In Briata et al. (AUCO Czech Econ Rev 6:199–208, 2012), the authors introduce a cooperative game with transferable utility for allocating the gain of a collusion among completely risk-averse agents involved in the fair division procedure introduced by Knaster (Ann Soc Pol Math 19:228–230, 1946). In this paper we analyze the Shapley value (Shapley, in: Kuhn, Tucker (eds) Contributions to the theory of games II (Annals of Mathematics Studies 28), Princeton University Press, Princeton, 1953) of the game and propose its use as a measure of the players’ attitude towards collusion. Furthermore, we relate the sign of the Shapley value with the ranking order of the players’ evaluation, and show that some players in a given ranking will always deter collusion. Finally, we characterize the coalitions that maximize the gain from collusion, and suggest an ad-hoc coalition formation mechanism.

  • Temporal clustering of time series via threshold autoregressive models:
           application to commodity prices
    • Authors: Sipan Aslan; Ceylan Yozgatligil; Cem Iyigun
      Abstract: Abstract The primary aim in this study is grouping time series according to the similarity between their data generating mechanisms (DGMs) rather than comparing pattern similarities in the time series trajectories. The approximation to the DGM of each series is accomplished by fitting the linear autoregressive and the non-linear threshold autoregressive models, and outputs of the estimates are used for feature extraction. Threshold autoregressive models are recognized for their ability to represent nonlinear features in time series, such as abrupt changes, time-irreversibility and regime-shifting behavior. The proposed clustering approach is mainly based on feature vectors derived from above-mentioned models estimates. Through the use of the proposed approach, one can determine and monitor the set of co-moving time series variables across the time. The efficiency of the proposed approach is demonstrated through a simulation study and the results are compared with other proposed time series clustering methods. An illustration of the proposed clustering approach is given by application to several commodity prices. It is expected that the process of determining the commodity groups that are time-dependent will advance the current knowledge about temporal behavior and the dynamics of co-moving and coherent prices, and can serve as a basis for multivariate time series analyses. Furthermore, generating a time varying commodity prices index and sub-indexes can become possible. Findings suggested that clusters of the prices series have been affected with the global financial crisis in 2008 and the data generating mechanisms of prices and so the clusters of prices might not be the same across the entire time-period of the analysis.

  • A joint chance-constrained programming approach for the single-item
           capacitated lot-sizing problem with stochastic demand
    • Authors: Céline Gicquel; Jianqiang Cheng
      Abstract: Abstract We study the single-item single-resource capacitated lot-sizing problem with stochastic demand. We propose to formulate this stochastic optimization problem as a joint chance-constrained program in which the probability that an inventory shortage occurs during the planning horizon is limited to a maximum acceptable risk level. We investigate the development of a new approximate solution method which can be seen as an extension of the previously published sample approximation approach. The proposed method relies on a Monte Carlo sampling of the random variables representing the demand in all planning periods except the first one. Provided there is no dependence between the demand in the first period and the demand in the later periods, this partial sampling results in the formulation of a chance-constrained program featuring a series of joint chance constraints. Each of these constraints involves a single random variable and defines a feasible set for which a conservative convex approximation can be quite easily built. Contrary to the sample approximation approach, the partial sample approximation leads to the formulation of a deterministic mixed-integer linear problem having the same number of binary variables as the original stochastic problem. Our computational results show that the proposed method is more efficient at finding feasible solutions of the original stochastic problem than the sample approximation method and that these solutions are less costly than the ones provided by the Bonferroni conservative approximation. Moreover, the computation time is significantly shorter than the one needed for the sample approximation method.
