    　View Summary

    Pneumatic rubber artificial muscles are nearly ideal for power assistance, medical care, and rehabilitation due to their lightweight drive unit made of rubber, which is soft and safe for human use. However, they have complex nonlinearities, including input saturation, hysteresis, and changes in static characteristics due to shrinkage. Additionally, when used with a human subject, the artificial muscle control system’s characteristics may vary based on the person’s physique, fitness, temperature, and the rubber’s deterioration. Therefore, it is desirable to be able to auto-tune the PID and other controllers in a short time before use. Data-driven controls such as FRIT and VRFT are suitable for auto-tuning in a short time. Among them, V-Tiger presented a procedure for predicting the actual closed-loop response and its Confidence interval. However, V-Tiger is not applicable to nonlinear systems with input saturation. This paper describes a procedure for (1) tuning PID gains by predicting the closed-loop response with V-Tiger in the presence of input saturation, (2) obtaining Confidence intervals for the predicted response affected by input saturation, and (3) how to use the Confidence intervals to apply this method to nonlinear systems.

    　View Summary

    Probability inequalities are known as an effective means to evaluate the upper bound of upper probability for an average of some random variables based on only limited stochastic properties, e.g., expectation, variance, and codomain for each random variable. Among them, Hoeffding probability inequality has been known as one of the best theoretical ways for evaluating the upper bound of upper probability about an average of several random variables based on limited stochastic properties such as expectation, variance and codomain in each random variable. In this study, the authors address a study for essentially improving the performance of Hoeffding probability inequality. In consequence, a new probability inequality with more superior performance than Hoeffding probability inequality is derived.

    　View Summary

    There are many studies about negotiation procedures for contract problems in supply chains. Several recent papers have considered a new negotiation procedure for a repurchase contract problem in a supply chain consisting of a manufacturer and a retailer. There, usually, are some wholesalers between a manufacturer and a retailer. Therefore, a supply chain including some wholesalers in addition to a manufacturer and a retailer should be considered. In this study, we call the supply chain in which three or more members are arranged in series the tandem supply chain. We, firstly, address a negotiation problem for a contract about wholesale and repurchase prices in the tandem supply chain in which three members, that is, a manufacturer, a wholesaler and a retailer are arranged in series. The whole contract in the tandem supply chain is composed of two contracts dependent mutually, i.e., the contract between the manufacturer and wholesaler and the contract between the wholesaler and retailer. The collaborative bargaining solution in the tandem supply chain consisting of three members is discussed. This paper, finally, formulates the tandem supply chain including several wholesalers.

  • The Process State Tracking Method in Poisson Process

    Shuto TANABASHI, Yasuhiko TAKEMOTO, Ikuo ARIZONO

    Journal of Japan Industrial Management Association   72 ( 3 ) 159 - 168  2021.10  [Refereed]  [Domestic journal]

    　View Summary

    Understanding the state transition of a process from the time series data obtained from the process is important from the viewpoint of both analyzing and controlling the process. In particular, it is important to clarify a turning point of the state transition, that is, the point of change in the process and to find the cause of the state transition by observing and analyzing the data from the process. This paper considers the method of detecting several change points in a process based on the likelihood theory and information criterion when a series of data from the process follows the Poisson process. Then, the method of finding any process state fluctuation and points of change is called “the process state track- ing method”. The validity and applicability of the process state tracking method introduced in this paper is confirmed through some numerical applications.

  • An analysis of steady-state distribution in M/M/1 queueing system with balking based on concept of statistical mechanics

    　View Summary

    The phenomenon of balking has been considered frequently in the steady-state analysis of the <italic>M/M/</italic>1 queueing system. Balking means the phenomenon that a customer who arrives at a queueing system leaves without joining a queue, since he/she is disgusted with the waiting queue length at the moment of his/her arrival. In the traditional studies for the steady-state analysis of the <italic>M/M/</italic>1 queueing system with balking, it has been typically assumed that the arrival rates obey an inverse proportional function for the waiting queue length. In this study, based on the concept of the statistical mechanics, we have a challenge to extend the traditional steady-state analysis model for the <italic>M/M/</italic>1 queueing system with balking. As the result, we have defined an extended analysis model for the <italic>M/M/</italic>1 queueing system under the consideration of the change in the directivity strength of balking. In addition, the procedure for estimating the strength of balking in this analysis model using the observed data in the <italic>M/M/</italic>1 queueing system has been also constructed.

    　View Summary

    <p lang="fr">&lt;p style='text-indent:20px;'&gt;Behavior that a customer who has just arrived at a crowded queueing system leaves without joining the queue is known as the phenomenon of balking. Queueing systems with balking have been studied continually as one of significant subjects. In this paper, the theoretical approach for the steady-state analysis of the Markovian queueing systems with balking is considered based on the concept of the statistical mechanics. Here, it can be easily seen that the strength of balking is not constant but various in each queueing systems. Note that the strength of balking means how degree a customer who has just arrived at a crowded queueing system leaves without joining the queue. In our approach, under considering the difference of the strength of balking for each queueing systems, we have proposed a statistical mechanics model for analyzing the M/M/&lt;inline-formula&gt;&lt;tex-math id="M1"&gt;\begin{document}$ s $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; queueing system with balking by introducing a parameter influencing the strength of balking. Further, we define a procedure for estimating the model parameter influencing the strength of balking. In addition, we consider a method of improving the performance of the M/M/&lt;inline-formula&gt;&lt;tex-math id="M2"&gt;\begin{document}$ s $\end{document}&lt;/tex-math&gt;&lt;/inline-formula&gt; queueing system with balking by utilizing the statistical mechanics approach.&lt;/p&gt;</p>

    　View Summary

    Random numbers obeying beta distribution are utilized for simulation analyses of various stochastic models. However, the procedure for generating beta random numbers is limited depending on the values of the parameters. Therefore, in this paper, a unified procedure for generating beta random numbers independent of the values of the parameters is investigated using Wilson-Hilferty approximation and Stuarts proposition.

    　View Summary

    Probability inequalities are used as a means to evaluate the upper bounds of upper probability for an average of some random variables based on finite stochastic properties, excluding the probability distribution functions of respective random variables. Note that in the case of applying the probability inequality, it is not necessary for the population of each random variable to be identical. Of the existing probability inequalities, Hoeffding probability inequality is highly regarded as an excellent probability inequality from the viewpoint of performance. Hoeffding probability inequality evaluates the upper bounds of upper probability for an average of some random variables based on limited stochastic properties such as expectation, variance and codomain in each random variable. However, we consider that there is a room to improve the performance of Hoeffding probability inequality. In this study, we demonstrate a technique for improving the performance of Hoeffding probability inequality in the case that the population of each random variable is not always identical.

    　View Summary

    In Japan, books and magazines have been distributed under the resale price maintenance and consignment sale systems. At present, the return rate of books and magazines has reached approximately 40 percent of the quantity of publications under the systems mentioned above. This is a severe problem from the viewpoints of both business and environment. For the purpose to solve this problem, a new sale system where wholesale price is reasonable while buyback price is inexpensive has been programmed and practiced. The wholesale and buyback prices are important contract parameters in the transaction program between publisher and bookstore. In this paper, the publishing supply chain consisting of a publisher and a bookstore is formulated as a mathematical model. Then, we have developed a new approach to solve the collaborative sale contract problem with wholesale and buyback prices as contract parameters.

    　View Summary

    The publications of books, magazines, music compact discs and newspapers in Japan are traded under the resale price maintenance and consignment sale systems. By these systems, the retail price is set uniformly nationwide, and dead stock is repurchased with the same price as the wholesale price. Therefore, it has not been required that bookstores in Japan actively develop an aggressive sale policy. On the other hand, a main policy of publishing companies is to deliver a large number of books in order to secure sales space in bookstores. As a consequence, in recent years, the returned goods rate of books has reached approximately 40 percent of the quantity of publications. This fact is getting a serious problem on management and environment. Under such a situation, a new sales system is considered where the wholesale price is lowered while cutting the buyback price is considered. In this case, both the wholesale price and buyback price are important contract parameters, and should be agreed on appropriately between the publishing company and bookstore. In this article, the supply chain contract problem between bookstore and publishing company is formulated. In particular, we assume that an accurate demand distribution of books is unknown from the reason why book has long product lifecycle and uniqueness. Accordingly, we apply the distribution free approach to solve this problem by using the limited information on mean and variance of demand. Then, a new decision procedure for contract parameters such as wholesale price and buyback price is discussed and suggested using the conventional coordination approach and game theory.

    　View Summary

    Japan has to urgently build a new system for securing electric power supply including renewable energy and for saving electric power. The electricity demand and the electricity supply based on renewable energy are influenced by the weather. Thermal power generation may also be affected by equipment failure. Therefore, plotting of a plan is required to avoid electric power shortage under inaccurate prediction for supply and demand of electricity. In this article, we propose a probability evaluation system to avoid electricity shortage. We also propose a method for setting the electricity saving rate to avoid electricity shortage while maintaining the present level of electricity shortage occurrence risk.

    　View Summary

    The quality of lots has sometimes been evaluated based on attribute properties such as the proportion or number of non-conforming items in the lot. There are two kinds of attribute sampling inspection plans with screening, called lot tolerance percent defective (LTPD) inspection and average outgoing quality limit (AOQL) inspection. These sampling inspection schemes have been designed in order to minimize the average total inspection (ATI), which means the expectation of number of samples to be inspected in the case of acceptance and number of samples inspected in the case that the lot is rejected. Taguchi proposed a concept of quality loss as a measure to evaluate the quality of items based on variable properties instead of attribute qualities such as the proportion of non-conforming items. This variable quality evaluation measure is known as "Taguchi's quality loss." Arizono et al. proposed acceptance sampling plans based on operating characteristics from the viewpoint of ensuring Taguchi's quality loss. Furthermore, Takemoto and Arizono proposed variable sampling inspection plans with screening for the purpose of ensuring the upper limit of maximum expected surplus loss after inspection indexed by Taguchi's quality loss. However, in the variable sampling inspection plans with screening considered in the above articles, minimizing the ATI in the screening sampling scheme has not been considered. In this article, we present design procedures for new variable sampling inspection plans with screening indexed by Taguchi's quality loss for the purpose of minimizing the ATI in conformity with conventional LTPD and AOQL attribute sampling inspection plans with screening.

    　View Summary

    The conventional reorder point system has been studied by many researchers, and is still an important issue in inventory management. In the continuous review system, the reorder point is set as an inventory level so that the shortage rate during the procurement lead time becomes less than or equal to the specified allowable level. The conventional design of the reorder point is based on the assumption that demand follows a normal distribution. However, this assumption is not always appropriate. In this study, the design of the reorder point using the limited demand information is proposed.

Especially, the process capability index C_&lt;pm&gt;, which is defined by the tolerance and deviation from the target, is called the Taguchi index. Boyles investigated the statistical characteristics of the C_&lt;pm&gt;, estimator, and also proposed a methodology for the C_&lt;pm&gt; control chart. Needless to say, since the process capability index C_&lt;pm&gt; is based on the concept of the quality loss introduced by Taguchi, it basically relates to the concept of cost performance. In this article, we consider the economical operation of the C_&lt;pm&gt; control chart in conformity with the expected total operation cost function based on the sampling cost, the sample cost and the surplus loss by means of ignoring the out-of-control state. Then, the economical operation of the C_&lt;pm&gt; control chart minimizing the total operation cost is investigated.

    In today&#039;s business environment, we are faced with some problems from the viewpoint of ecology; one important problem being the reuse of used products. Used products are generally collected and stored as reusable resources. The remanufacturing production system meets the demand by remanufacturing products utilizing reusable resources in addition to the production of new products. In this case, the flow of reusable resources is called reverse-logistics in contrast to the flow of demand. Naturally, the optimal production policy of the remanufacturing production system with reverse-logistics s...

    　View Summary

    The quality of a lot has sometimes been evaluated based on attribute properties such as the percentage of nonconforming items or the number of nonconforming items in the lot. On the other hand, Taguchi has proposed the concept of &quot;quality loss&quot; as the evaluation measure of quality of items based on variable properties. Concretely, Taguchi&#039;s loss function has been defined as a quadratic function based on the departure from the target value of an item. Recently, from the viewpoint of assuring the quality loss based on Taguchi&#039;s loss function, a single sampling inspection plan based on operating characteristics has been proposed. This sampling procedure has been designed for the purpose of assuring both the specified producer&#039;s risk for the lot with an acceptable quality loss limit and the consumer&#039;s risk for the lot with a rejectable quality loss limit. However, the disposition of the rejected lot isn&#039;t specifically declared in the sampling inspection plan mentioned above. While, there is a sampling inspection plan with screening by attribute in which the rejected lot in the sampling inspection is thoroughly inspected and nonconforming items are exchanged for conforming items or repaired. In this sampling procedure, the sampling plans have been designed for the purpose of assuring the percentage of nonconforming items in every lot and the upper limit of the average outgoing quality level as the average outgoing percentage of nonconforming items. In this article, the quality evaluation based on Taguchi&#039;s loss function is adopted instead of the quality evaluation based on the percentage of nonconforming items as lot quality. Then, we propose a single sampling inspection plan with screening by variable indexed by Taguchi&#039;s loss function for the purpose of assuring the upper limit of the maximum expected surplus loss.

    In general, a process starts in an in-control state and then some assignable causes change the process state to be out-of-control. It is worthwhile to utilize serial data in addition to the current data in order to monitor the process state, for which the CUSUM and EWMA control charts are useful. Performance of the CUSUM and EWMA control charts has been investigated under the condition that the process starts in an out-of-control state. However, as mentioned above, a process usually starts in an in-control state. In this paper, we present CUSUM and EWMA control charts based on the Kullback-Leibler information. Then, and investigate their performance under the condition that some assignable causes change the process from the in-control state to an out-of-control state. Because it is also important to discriminate the switchover time of the process state, we propose a discrimination procedure for the process state switchover time based on the information criterion.

    We have contrived these control charts in order to detect the out-of-control state of the process.

In quality management, it is important to detect the out-of-control state and to remove the factor by which it is caused. Although conventional control charts, in which the state of the process is judged only on output data of products from the present process, are useful statistical tools for detecting the out-of-co...

    Manufacturing systems are classified into make-to-stock (MTS) systems and make-to-order (MTO) systems. In particular, the MTO manufacturing systems have been applied to many enterprises in order to react to consumer's uncertain demands and various requirements. Until now, in the studies for the order splitting policy to some original equipment manufacturers (OEMs) under the MTO manufacturing systems, the expectation of the lead time has been mainly considered. In general, the lead-time has the variability because of the fluctuations of the processing time and the demand. Therefore, when the optimal operation of the MTO manufacturing systems is investigated, we should consider the possibility of the delay for the appointed date of delivery of products. In this study, taking the penalty of the delay of delivery into consideration, we investigate the order splitting policy to two OEMs having the difference in the processing cost and the capacity.

    　View Summary

    Recently, the rapid growth of data-acquisition technology and the use of online computers for process monitoring have led to an increased interest in the simultaneous surveillance of several related quality characteristics or process variables. In general, related quality characteristics are assumed to be distributed as multivariate normal random variables. As a result, the multivariate control chart for the mean vector has been studied extensively in many works. Popularly, in the case that the quality characteristics are distributed as univariate normal random variables, the mean and variance are simultaneously treated as the objectives of surveillance. From this point, in the case that the quality characteristics are distributed as multivariate normal random variables, the mean vector and variance-covariance matrix should be simultaneously treated as the objectives of surveillance. Kanagawa et al. have proposed a (x^^-, s) simultaneous control chart that enables the user to monitor both changes in the mean and variance in a process simultaneously based on Kullback-Leibler information when the quality characteristics are distributed as univariate normal random variables. In this study, as an extension of the (x^^-, s) simultaneous control chart, we propose a multivariate (X^^-, S) simultaneous control chart that enables the user to monitor both changes in the mean vector and variance-covariance matrix simultaneously. Further, the evaluation of the power for the proposed multivariate (X^^-, S) simultaneous control chart is also considered.

    　View Summary

    This article deals with the hypothesis test for the homogeneity of two normal populations. The likelihood ratio test is a usual method for such testing. In general theory, the asymptotic distribution of log-likelihood ratio statistics as testing statistics is well known under the null hypothesis, so we may design the test based on the asymptotic distribution. On one hand, the asymptotic distribution of log-likelihood ratio statistics is also considered under the alternative hypothesis. However, in the case that sample sizes are not so large, the asymptotic distributions are not so accurate under the arbitrary hypotheses. Recently, Arizono et al. have derived the cumulant generating function for the log-likelihood ratio statistics under the null hypothesis when the sample size is finite, and enabled to design accurately the null hypothesis test for homogeneity of two normal populations. However, the stochastic properties of log-likelihood ratio statistics under the alternative hypothesis and the power of testing have not been investigated in theory. Therefore, we consider the stochastic properties of log-likelihood ratio statistics under arbitrary hypotheses in this article. Concretely, the cumulant generating function for the log-likelihood ratio statistics and the cumulant of arbitrary order are derived under the arbitrary hypotheses when the sample size is finite. Further, by using the cumulants of log-likelihood ratio statistics derived in this article, we develop the approximation for the distribution of log-likelihood ratio statistics, and propose the theoretical evaluation of the power for the homogeneity hypothesis test.

    情報系学科は文理融合的性格を持つ。発表者が所属する学科名の「経営情報」または「経営情報学」という用語は高校生には十分定着した状況ではなく、入学した学生が、文系、理系出身を問わず、学科の特徴・学習内容に明確なイメージを持っていない例が見られた。そこで本研究では、公開講座などの高大連携活動を通し、Web教材と公開講座などの対面型講座を併用した、経営情報分野の紹介と浸透を効果的に行なう教材開発を企図した。これまでにWeb教材については一定数の教材公開を実施し、今年度からは、公開講座などをWeb教材と同じテーマで提供することを開始した。これらの活動も含めた現時点までの進行状況を報告する。

    JIS Q9000:2006において,検査は,「必要に応じて測定,試験またはゲージ合せを伴う,観察及び判定による適合性評価」として規定されている.従来の検査での適合・不適合による品質評価は,適合性を判定するための基準である要求事項が目標値と許容差であり,許容差内に品質特性値があるかどうかによるものであった.一方,適合・不適合の概念とは別に,Taguchi Methodとよばれる方法論によって提案された品質損失という概念が存在する.これを評価する一つの方法として損失関数が開発された.損失関数は製品および工程の開発・設計などの様々な場面での意思決定に応用されている.本稿では,品質損失を与える損失関数の検査への応用に関して論じる.まず,損失関数の検査への応用の方法について整理し,さらに筆者が研究を進める,品質損失を検査における保証の対象として想定した抜取検査に関する一連の研究について概説する.最後に,今後の展開について論じ,本稿を総括する.
