Manufacturing philosophies like Just-In-Time are largely held responsible for the rapidly worsening traffic situation. In some European countries, laws which restrict truck traffic to day-time hours have been issued in order to cope with nuisances like noise and air pollution. With 'Hybrid Manufacturing', where an anticipatory production is implemented in a JIT system, products can even be assembled during times when part replenishment is banned. Not only does this method boost the system's productivity, as idle capacity is used for anticipatory production, but it also results in a highly leveled work load for all upstream production processes that precede the affected part-production lines. Thus, this method makes it possible to deal with restrictions on transportation while having a positive effect on the workload of preceding production lines. A numerical example demonstrates the effectiveness of this method.

We often experience network design problems with multi-commodities and capacitated links, such as communication networks, road networks, transportation networks and so on. They are translated so-called capacitated multi-commodity network design problems, We present a new solution method for finding a lower bound of the capacitated multi-commodity network design problem. A lower bound is used for branch and bound solution methods and for the guarantee of heuristic solution precision. Our new lower bound solution method consists of 1) finding cutset constraints from cutsets on the network ; 2) finding cutting plains derived from cutset constraints ; 3) approximately finding dual solutions of the problem with cutting plains. Numerical examples are given to illustrate efficiency of our solution method.

Conventionally, the diagnostic expert system have been developed using maintenance engineers. But such a system has many problems. Firstly, these systems need failure data, but there are no data for advanced production equipment. Secondly, a generic system is needed for the advanced production equipment. This paper reveals the necessity of a diagnostic system built by a designer of production equipment. Also a method of knowledge representation is presented. In addition, it is shown that the extention of a constructed system to another version is possible by using the concept of standardization applied successfully at the design stage.

A single-machine scheduling method is proposed for minimizing the total cost consisting of flowtime cost and asymmetric penalty cost of earliness-tardiness, when all jobs have a relatively small common due date and an identical cost function. In this case, it is necessary to schedule jobs so that the starting time of the first job is nonnegative. Dominance conditions necessary for an optimal schedule are derived to this constrained scheduling problem. An algorithm based on these conditions is proposed to find an optimal schedule. Numerical examples are demonstrated to show the effectiveness of the proposed method.

Organizational research in terms of a self-organizational model has preceded in the conceptual field, In this paper, we propose the argument of a garbage can model which represents an orgainzational selective process, and propose a mathematical self-organizational model of the organization. The effectiveness of this model is confirmed by applying it to the organizational change due to the introduction of TQC as a real self-organization.

Self-help devices help workers who have physical disorders, including visual and auditory disorders, to perform their work efficiently. Many kinds of self-help devices have been developed, and they are improved upon in accordance with the disabilities of users. However, self-help devices are not evaluated in terms of both functionality and effectiveness. In this paper, a new method is proposed to evaluate the functionality and effectiveness of self-help devices for operations by taking into account tasks and physical functions. The method is applied to 273 self-help devices. It is made clear through the survey that an evaluation method is applicable and useful in selecting and also developing self-help devices.

Chain sampling plans allow significant reductions in sample size under conditions of a continuing succession of lots from a stable process. One condition under which such plans can be applied is that for which lots are expected to be essentially of the same quality. Under this condition, the chain sampling plans are weak in detecting a change in the process state. In this paper, a modified chain sampling plan is presented. The weak point of this plan has been improved upon by attaching importance to the latest information of lot quality by means of a double sampling plan to a submitted lot. In order to compare the proposed sampling plan with the conventional chain sampling plans, simulation results for rapidity of detecting a change in the process state and the operating cost are also presented.

This paper suggests a method for designing robotic mixed product lines. The validity of the method was proved through comparison among the solutions which were solved by this method and a branch-and-bound method for designing the lines. The suggested method was constructed as an expert system. The roles of this method are to select a kind of robot for each work station and to assign work to each robot from the viewpoint of the efficiency maximization of performing desired production plans. Values of several parameters for designing must be determined rationally. A searching procedure of the values is prepared.

The existing software complexity measures are numerous and diverse. The program complexity is one of the useful main measures for objective nd quantative evaluation of software. However, the known methods to measure program complexity are insufficient in that each method measures only one factor (e. g. program size, control flow, data flow etc.). Program complexity is, however, caused by many different factors, so measuring only one of them can not give reliable results. In this paper, we propose a new measure called HMCM (Hybrid Module Complexity Metrics), which combines the dependence among modules, and illustrate the effectiveness of the proposed measure.

According to the diversification of customer demand, the type of production system is changed from a single production line to a mixed production line. From this point of view, the rule and significance of flow-shop scheduling is greater than before. For a company like this, the development and utilization of effective scheduling are desired. In this paper, the new priority rule for the flow-shop problem of three machines with no in-process waiting, is proposed. Moreover, this method is compared with other methods for maximum flow time, utilization, idling time and blocking time. The effectiveness of this research is examined by the simulation.
