    It is important for health care to settle a shortage of nurse these day, since an aging society is just coming in. They are necessary for nurses to reduce nurses' burden of irregular work schedule and to optimize a nurse schedule with each nurse's preference, because nurses' work is too burdensome for nurses to work now. However it is impossible to optimize a surse scheduling problem (NSP) by permutation as NSP is decided under many complex constraint conditions. In this paper, NSP is solved by Genetic Algorithm (GA) that is efficient to such a combined optimization problem. A proposed procedure to NSP takes account of each nurse's preference which has never been studied. Furthermore, the affect to result is investigated with various, parameters which are important in GA to solve such a problem like NSP.

    This study is revealed optimum efficient division of human work from the factors of the bewilderment and the changing of working distance. As a result, 1) From the viewpoint of the working times, bewilderment is revealed if the number of the kind of parts becomes more than five, and reveal increasingly if the number of the kind of parts becomes more than twenty. 2) By considering bewilderment, it is possible to calculate the working times from the number of the kind of parts and movement distance. 3) It is possible to decrease bewilderment by 50%. From these results and the estimated formula, it is revealed the range of optimum efficient division of human work.

    This paper discusses the factors affected by utilization rate for flow type machining system. The relations between utilization rate and production rate are showed in the one machine problem at first. And, the utilization rate which is calculated by five kinds of idle time is defined and analyzed for the multi-stage flow type machining system. These idle times are tool changing time, no-chip-flow time, balance loss, failure time and processing time for defective works. A new design method of transfer line is proposed to decide the number of machines. The utilization rate of constructed line by the method is calculated in a numerical example.

    In this paper, we propose a Case-Based Reasoning (CBR) approach for nonpreemptive scheduling of independent jobs n to unrelated parallel machines m where the time required for the processing of a job on a machine is a function of both the job and the machine, and the objective is to minimize the makespan. The CBR approach makes direct use of previous cases (problems and their solutions) and finds near-optimal solutions based on similarities between problems and cases. Our discussion is focused on investigating the efficiency of the CBR approach corresponding to the degree of similarity between problems and cases. Computational experiments show that this approach can find very promising solutions in very short running times even if problems are not very similar to cases and so it is an efficient and effective approach.

    This paper discusses system concepts for Work Design from the viewpoint of a general system theory. There are 2 main aspects in perceiving a system, when using Work Design as a system designing method. One is to consider a system to be an arbitrary product of thought that has no entity. The other is that it also is a definite entity made up of matter and people. In this paper, it has been tried to organize and describe a system as an entity and the system and as an idea as formally as possible, and to clarify the system concept used in Work Design. The features of the system designing method with Work Design have also been organized.

    We first extend the fuzzy regression analysis formulated with symmetric triangular fuzzy number coefficients to the case of non-symmetric triangular and trapezoidal fuzzy numbers. We show that some difficulties in the fuzzy regression analysis can be remedied by this extension. Next we propose an approach to non-linear fuzzy regression using fuzzy neural networks with fuzzy number connection weights. Leaning methods are proposed for the following three kinds of training data : real number data, real number data with membership values, and fuzzy data with fuzzy number outputs. Last we apply the proposed approach to the determination problem of type 2 membership functions. A membership value is given as a fuzzy number such as "small" and "large" in a type 2 membership function.

    We deal with normal sequence data, for example, from real-time process control, which has been analyzed by the Cumulative Sum Test. The purpose of the paper is to give a new procedure for the change detection problem, which detects a change of the mean or the variance, and gives these estimators after the change. First, using Minimum Description Length (MDL) criterion, we propose a procedure which deals with the detection and the estimation consistently. Second, we give a method to adjust an error detection probability and a delay length of detection, which are in trade-off relation. Finally, the new procedure compares favorably with the Cumulative Sum Test.

    In this paper, a rule generation method based on a classifier system is proposed to automatically generate linguistic classification rules for multidimensional pattern classification problems. Each linguistic classification rule is handled as an individual in the proposed method. Genetic operations such as crossover and mutation are applied to the linguistic classification rules. A fitness value of each rule is defined by the number of correctly and wrongly classified training patterns. Because a small number of linguistic classification rules are automatically generated from training patterns by the proposed method, it can be viewed as an acquisition tool of linguistic knowledge. The effectiveness of the proposed method is demonstrated by computer simulations on two-dimensional classification problems and a classification problem of wine data with thirteen attributes.

    This paper studies the two types optimal configuration problems of Flexible Manufacturing Systems with large scale in the case of fixed vs. dynamic routing. First, a simplified calculation of throughput and practical algorithms are presented to short on the computation time. Next, it is ascertained that the proposed algorithms are more effective than implicit algorithms in the respective routings. Finally the performance of fixed routing model with optimized routing probabilities is compared to dynamic routing model, and an example of the optimal configurations for these models is given.
