This report describes the statistical nature about the changing state of assembly systems in Japanese machine industries.Analizing the results of a questionnaire survey on assembly plants conducted in 1978,several remarkable trends about automatic assembly, work structuring and assembly lines are presented. The practices in three areas covering the computerized assembly line balancing, mixed-model sequencing and scheduling are also described.

MRP systems have been developing in the U.S.and their applications for many kinds of industries and production organizations. In this paper, 1)I will report an introduction to MRP systems, 2)backgrounds underlying MRP systems which from the main stream in the production control systems in the U.S., 3)a historical phase dealing with progress and features of MRP systems, 4)the current trends of MRP systems in the Unites States and Japan.

In this paper, sufficient conditions are presented to decide the precedence relation between neighboring two jobs by means of adjacent pairwise interchange methods for minimizing mean flow-time in n/m flow-shop scheduling. On the basis of the sufficient conditions, a computational algorithm is proposed for an optimal or near optimal solution. The mean flow-time obtained by this algorithm indicates an average approximation ratio of 86% over 160 examples. This algorithm can be executed within the time proportional to n×m^2,where n and m are the number of jobs and machines in turn.

This paper is intended to desctibe a method for the efficient representation of the probability density function of a population by the variation diminishing spline function. The variation diminishing spline functions have two advantages : 1)They have the"shape-preserving" properties. 2)They are represented by a few knots and nodes. From these advantages, they are suitable to represent the probability density functions, and the mean and the variace are easily calculated by a few knots and nodes.

This paper deals with a field of job-shop scheduling problems. The mean and the standard deviation of flow-times are derived from the various conditions such as the number of machines and the machine utilization which specify the characteristics of a job-shop. A method for due-dates assignment is proposed, on the basis of the mean and the standard deviation of flow-times together with a due-dates adjustment factor. The numerical experiments show that this method is capable to assign the more rational due-dates than previous TWK due-dates.

This paper analyzes production costs under a production planning to meet demands. These costs are divided into two categories : "additional cost" and "basic cost". The latter depends on technical levels and intensity of labour etc. The former, which involves overtime-undertime cost and inventory holding cost etc., represents the effectiveness of production planning.It is shown that the criterion to minimize total costs is equivelent to minimize additional costs on condition that the basic costs are deterministic. The additional cost function of overtime-undertime is newly formalized, excluding a contradiction of the usual formulation of overtime-undertime costs.

This paper concerned with the relationship between manufacturing industrial location and the various factors affecting it.First, the factors inherent in the region are analyzed by using entropy model.Then, the impact on industrial location of political factors controlled by the authorities concerned is investigated. This is carried out by means of our behavioral simulation model including the entropy model.
