It is a very interesting problem to find that how many successive processes should be connected by using a transfer machine, an over-head conveyer or any other device as the loss due to stopping the united process for tool changing or maintenance increases roughly proportionate to the number of processes being connected. System design to solve the problem that how many successive processes should be connected may be defined as the method to obtain the connection which minimize the following total lose L : L = Increased cost due to stopping united processes + cost needed for storaging and keeping a space between each two united processes. One of the solution for the above problem is studied in this paper.

Some characteristics of sequences generated by the multiplicative congruential method are studied for modulo M = 10^e.The generated sequences may be classified into 8 groups. Initial values and revised methods of random number generation are given from this classification.

An estimation of the smoothing parameters is formulated in which the data of demand shows the periodicity. The minimization of squared forecasting errors is adopted as a criterion of the estimation. Three algorithms for the minimization are attained through the use of i) Gradient method, ii) Gauss-Newton method, and iii) CRST method. In the latter case, several constraints on the smoothing parameters can be taken into account. Each algorithm is able to become an element of a forecasting system with the pre-estimation procedure and the test of forecasting errors.

In a flow line system designed by the mixed lot of operation times to each of the different parts, interference time exists because of the variations of the operation times. In this paper, we consider a theoretical solution of this interference time and its elimination. We suggest the delay of production time that seems to arise in actual application of this elmination, and the actual advantageous application of this system by applying the theoretical formula for little more delay than seems to arise when the interference time is not eliminated.

This paper on working time in the learning process contains some suggestions for a method of estimating its distribution, and also some results obtained by empirical distributions. A study of the empirical distributions was conducted with a view to obtaining information concerned with the distribution of working time and its parameters in the learning process. This paper hypothesizes that working time has been expressed by a log-linear model.

In general, the decision problems are often formulated as the integer programming problems with 0-1 variables. The decision makers dealing with such problems in the firm are often based on the viewpoint of "satisfying multiple goals, "which means aiming at each aspiration level, instead of "maximizing a single goal." This paper presents the practical formulation and solution for the Multi-Goal Programming Problems with 0-1 variables which often appear in capital investment decision problems.

An analogy of the design of flow line in job shop reveals an important problem from the view point of total production efficiency. In this paper we suggest an advantageous judgment formula from the comparison of total production time in this system to the previously used lot production system and job shop production system. The application of the system from the above mentioned formula is mode feasible through the grouping of different operations and through the degree of analogy that must be solved by the group technology, etc.

In the study of measuring methods for clerical personnel numbers in an office, fast and easy applications are required. The methods use the input and output time distance relations of clerical unit to and from the office, i.e. forms and reports, rather than a time study of each clerical work operation. The author's new theory is also utilized in which the mean of output time distance depends on the larger variable between the mean of input time distance and that of service time in the office per clerical unit.
