    This study focuses on the effect of listening to music before simple repetitive tasks. Research on the Mozart effect suggests that listening to Mozart contributes to an enhanced arousal level and a positive mood which influences performance on a variety of tasks. From that research, this study hypothesizes that if music is expected to make workers' motivation rise, listening to music before doing a task could lead to inducing a positive affect and improving the performance on a simple repetitive task. The effectiveness of listening to music before tasks was examined through experiments. In the experiments, 44 subjects were required to do two sessions. In one session, they were required to do the simple repetitive task after listening to the music through which they expected their motivation could rise. In the other session, they were required to do the task without the music. There were 12 subjects who did the copying task in German, another 16 subjects who did the copying task in French, and another 16 subjects who did the mental rotation task as the simple repetitive task. The results of the experiments revealed that the positive mood of the subjects in the case of listening to the music before the task was significantly higher than in the case of no music, irrespective of the task. The results also revealed that the performance in the case of listening to the music before the task was significantly better than in the case of no music, irrespective of the task. These results revealed the effectiveness of listening to music before simple repetitive tasks in terms of positive mood and task performance.

    A production and inventory system under a base stock policy is considered with advance demand information. Demand arrival is informed in advance with a fixed time, called demand lead time. An arrival process of demand is Poisson, and processing time is assumed to be deterministic. The arrival rate of demand is assumed to be nonincreasing in the demand lead time. In this system, the optimal number of base stocks and optimal demand lead time are analyzed. In addition, for large demand lead time, a release lead time is introduced, in which case the order for processing is postponed after each arrival of advance demand information. The relationship between release lead time and demand lead time is also discussed.

    In this paper, we focus on multiobjective stochastic linear programming problems, and propose an interactive fuzzy decision-making method to obtain a satisfactory solution. In the proposed method, it is assumed that the decision maker has fuzzy goals for not only permissible objective levels of a probability maximization model, but also permissible stochastic levels of a fractile criterion optimization model. After eliciting the corresponding membership functions, two membership functions for permissible objective levels and permissible stochastic levels are integrated through the fuzzy decision. An interactive algorithm is proposed to obtain a satisfactory solution in the integrated membership space, in which both permissible objective levels and permissible stochastic levels are simultaneously considered.

    This paper derives conditions of aggregation rules in the generalized nested logit (GNL) model to avoid the aggregation problem. In respect to control of increasing parameters, it is useful for researchers to reduce the number of nests or alternatives in the GNL model. Therefore, aggregation rules in the GNL model are important for researchers to reduce time to analyze models or estimate their parameters. First, we demonstrate two simple aggregation rules (the arithmetical mean and the geometric mean of definite utilities in nests) that cannot solve the aggregation problem using actual scan panel data. Second, we derive the three following aggregation rules of the GNL model to avoid the aggregation problem: 1) aggregation of nests which results in three conditions in the brand choice model, 2) aggregation of alternatives which results in two conditions in the same model, and 3) aggregation of nests which results in six conditions in the traffic mode choice model. Finally, we conduct comparison analysis of aggregation rules among the multinomial logit (MNL), nested logit (NL) and GNL models in two cases: 1) aggregation of nests, and 2) aggregation of alternatives in the brand choice model. As a result of this comparison, it is indicated that 1) the relationship among aggregation rules in the MNL, the NL and the GNL models is consistent with the relationship among choice probabilities in these models, and 2) in limited but many cases, each definite utility component has maximum and minimum values.

    The transactions of books and magazines in Japan have been made under the resale price maintenance and consignment sale systems. Nowadays, the return rate of books and magazines has reached approximately 40 percent of the quantity of publications. This is a serious problem from the viewpoints of both business and the environment. On one hand, a new sale system where the wholesale price is inexpensive while the buyback price is cheap has been programmed and practiced. In the new sale system, the wholesale price and buyback price are important contract parameters. In this article, we formulate a book and magazine distribution system with publisher and retail store as a mathematical model. Then, a new decision procedure for contract parameters such as the wholesale price and buyback price is discussed and suggested using the conventional coordination approach and game theory.

    In fixed order quantity systems, uncertainty of procurement lead time is expressed as a set of scenarios with occurrence probabilities, and a cumulative distribution function (c.d.f.) of shortage rate is evaluated under the set of scenarios for any value of reorder point. According to stochastic ordering, a "robust optimal reorder point based on an allowable shortage rate" is defined as the minimum value of the reorder point satisfying the condition that the c.d.f. of shortage rate is greater than or equal to the basic c.d.f of shortage rate predetermined by a decision maker. For the other case when the reorder point is determined to minimize the total additional cost consisting of safety stock holding cost and backordering cost, an optimal reorder point is found under each scenario and the closeness for any value of reorder point is evaluated under every scenario, resulting in the c.d.f. of closeness for the set of scenarios. The rank for any value of the reorder point is calculated according to stochastic ordering to express how close the reorder point is to the optimal reorder points under the set of scenarios. A "robust optimal reorder point" is defined as the value of the reorder point with the minimum rank. These robust optimal reorder points are obtained and their features are investigated for some numerical examples.

    This paper evaluates the performance of a supplier hub which supplies key components to neighboring manufacturers. The system is proposed by a third-party logistics provider that imports, stores and delivers glass panels on behalf of an international supplier. Under an information-sharing initiative, the hub can access inventory information of two major manufacturers and is responsible for making all replenishment decisions for the supplier. To evaluate the new proposal, we develop a multi-objective swarm optimization algorithm incorporating a simulation program and Kriging forecasts to identify non-dominated solutions that constitute the trade-off curve between fill rate and total inventory. Results suggest that the information-sharing initiative dominates existing operations if manufacturers prefer a very high fill rate or delivery times from the supplier to the hub are long.

    A patent map, a visual representation of related patent information, is an effective strategic tool for analysis of patent application trends. In particular, technology-effect patent maps are commonly used. One of most important reasons is that patent examinations are based on terms related to the technology and effect of the inventions. However, conventional patent mining tools are not able to make a technology-effect patent map. In order to generate technology-effect patent maps automatically, we propose a method for extracting information on the effect and the technological terms from patent documents. Our proposed method is summarized in the following three steps. (Step 1) Extract expressions containing the technology and effect terms using statistical information and initial clue expressions. (Step 2) Extract technology terms in the above expressions using character-string comparison between patent claims and the expressions. (Step 3) Extract effect terms using grammar patterns. Our method achieves high precision (85.0%) through use of frequent expressions, clue expressions and grammar patterns.

    Technological development and production processes require statistical process control in the use of alternative techniques to evaluate a productive process. This paper proposes an alternative procedure for monitoring a multivariate productive process using residuals obtained from the principal component scores modeled by the general class of autoregressive integrated moving average (ARIMA) and the generalized autoregressive conditional heteroskedasticity (GARCH) processes. We seek to obtain and investigate non-correlated and independent residuals by means of X-bar and exponentially weighted moving average (EWMA) charts as a way to capture large and small variations in the productive process. The principal component analysis deals with the correlation among the variables and reduces the dimensions. The ARIMA-GARCH model estimates the mean and volatility of the principal components selected, providing independent residuals that are analyzed using control charts. Thus, a multivariate process can be assessed using univariate techniques, taking into account both the mean and the volatility behavior of the process. Therefore, we present an alternative procedure to evaluate a process with multivariate features to determine the level of volatility persistence in the productive process when an external action occurs.
