    The present paper proposes a task description method for print advertisement styling processes adopting actions and protocol data that can be obtained by video recording. The proposed description illustrates the styling processes in time-line style, and it enables us to easily grasp the transitions of styling forms, actions, and cognitive steps estimated from protocol data. In addition, we show basic ideas that allow us to diagnose actions/cognitive processes relating to creativity (i.e., generating novel styling forms and novel goal settings during the styling processes). We carried out a series of experiments in which a conventional print advertisement production task was reproduced with a well-skilled designer. We conducted a preliminary application with the proposed method to data obtained in the experiment. From this application, we could obtain implications that the description makes it possible to clarify the states of the styling processes (i.e., efficiently progressing or fixating). Additionally, we showed that the designer's behaviour in terms of the above-mentioned creativity can be quantitatively evaluated using the proposed indices.

    There exist many studies regarding sequencing problems in mixed-model assembly lines. The goal of many of these studies is to level the workload at each workstation on the assembly line in order to reduce the line stoppage time as much as possible. In the real mixed-model assembly lines of vehicles, the total workload of each vehicle is used to level the workload at each workstation. This is the same as the assembly lines having only one workstation. This is the reason why it is very difficult to maintain data on all the processing times of each workstation as listed in the following. (1) There exist many workstations in vehicle assembly lines. Moreover, the number of specifications for a vehicle is very large. (2) Continuous improvements for operations at workstations and assembly line balancing are always performed. As a result, we approach a sequencing problem for mixed-model assembly lines with only one workstation. There have been very few studies regarding this problem. Therefore, we have investigated it and obtained related characteristics. We propose an approximation algorithm using these properties. It is shown by numerical examples that the proposed algorithm can find a good sub-optimal solution.

    In this paper, we propose a critical temperature search method which is one of the approximation methods for solving job shop problems. The job shop problem is a combinatorial problem, and the objective for job shop problems is to search the best makespan of jobs and find a solution that specifies the sequence of job operations that minimize the makespan for all machine tools. The given conditions of a job shop problem are the number of jobs, the operation time of each job, the machine tools which process the operations of the jobs and are previously identifed, and the sequence of the machine tools for the job. The critical temperature search method is constructed by two algorithms: phase 1 and phase 2. The phase 1 algorithm is the simulated annealing (SA) algorithm itself. However, an adaptation of phase 1 is different from the ordinary SA algorithm. In the SA algorithm, an important parameter is temperature, and the temperature is gradually decreased from high to low by a cooling function. In phase 1, the temperature is gradually increased from a low temperature, higher than zero. Then, if the temperature rises over a critical temperature, which is defined in this paper, phase 1 may be terminated. The phase 2 algorithm is a fixed-temperature SA algorithm, and for the fixed-temperature SA algorithm, the critical temperature is applied as the fixed temperature. Using the critical temperature searched in phase 1, the phase 2 algorithm will try to find the best makespan of the job shop problem. The search process for the critical temperature using the phase 1 algorithm may require much time. Oppositely, if a moderate critical temperature is searched during phase 1, the acceptable makespan of the job may be quickly found in phase 2. The job shop problem considerd was a model requiring a daily job operation problem to be solved. The daily job operation problem was an order set of small job operation changes and/or small changes in job number. If there is a similar job operation environment, the prior critical temperature may be able to be adapted to solve similar job operation problems. Therefore, the adaptive job operation schedule may be quickly obtained using the critical temperature search method. To prove efficiency, benchmark problems of mt 10, abz 5, abz 6, yn 1, yn 2, yn 3, yn 4, and 10 hard problems were tested using the critical temperature search method. The error against the optimum results or the best known solutions was a small percent, and the search time was only a few minutes when using a 3.014GHz Intel CPU.

    The vehicle routing problem is one of the basic problems in physical distribution systems, and this problem has wide applications such as the delivery of commodities to retail stores and so on. Therefore, numerous studies on this problem have been submitted. In most of these studies, it is implicitly supposed that each vehicle must travel just one route in a working day. However, actually, one vehicle often travels two or more routes in one day. Moreover, in most of the previous studies, the objective is to minimize the total distance traveled by vehicles. However, it is often important to minimize the maximum operating time of any vehicle, and the travel time between customers is usually asymmetric. We propose a near-optimal solution for the asymmetric vehicle routing problem with multiple use of vehicles on the basis of Lagrangian heuristics. First, we formulate the problem as a mixed 0-1 integer programming problem. Next, we present a method to determine the lower bound of the problem by solving the assignment problem and the semi-assignment problem, and we propose a method to reduce the problem. Moreover, we present a method to determine a near-optimal solution of the problem by successively decreasing the difference between upper and lower bounds. Finally, we verify the effectiveness of the proposed method through computational experiments.

    In corporate activities, the reduction of environmental burden has become an important issue. Accordingly, there is tremendous effort made to disclose corporate emission data in environmental reports. According to a questionnaire survey conducted by the Japanese Ministry of Environment in fiscal year 2003, 38.7% of the companies listed published environmental reports. In the investigation in 2005, 47.0% of the companies listed made reports, so it can be pointed out that the ratio of enterprises making environmental reports is increasing. Based on the above, this study proposes an evaluation technique of environmental performance which realizes inter-company comparisons. This technique uses an integrative technique of environmental burden which translates the emission amounts of two or more environmental burden substances, to a single measurement. When existing integrative technique is considered in terms of external evaluation, these techniques assume that all of the necessary data for calculations are disclosed. However, today's disclosure level is not sufficient for the evaluation to work properly. This method imposes estimated emissions including penalties for those companies with undisclosed emission data. The penalty is calculated for each substance using a nondisclosure emission penalty factor. This enables external evaluation with the current disclosure level, and provides disclosure incentives to the enterprises that disclose emission data. In addition, this technique defines the organization boundaries and business scope of emission data, and compensates each company's size in its industry. Therefore, it can compare enterprises of different types and among different industries as well.

    This paper proposes a weight sum evaluation method that uses a range of weight ratios under a hierarchical structure of criteria and includes an added Data Envelopment Analysis (DEA) viewpoint. In a multi-criteria selection problem, one of the most popular methods to deal with this selection problem is called weighted sum evaluation. This evaluation means that a decision maker decides the criteria's weight and then calculates the weighted sum. The famous Analytic Hierarchy Process (AHP) method is used to solve this problem, which provides many theorems and cases. However, it is difficult to judge to what extent the result of this weighted sum is valid due to several reasons. One reason is that a decision maker must understand the problem to understand the correct weight. But in many cases, because time and cost are limited, such correct understanding is difficult. In addition, even if the decision maker can decide the weight under the circumstances, the alternative which was chosen by weight sum is not perfect because a little difference of the weight affects the evaluation result. Therefore, a sensitivity analysis is recommended in many cases. However, conducting this sensitivity analysis is still difficult because of the existence of many criteria and their hierarchical structure. This paper proposes a new method and applies an example of plant evaluation using the criteria of the Malcom Baldridge National Quality Award (MBNQA), and shows the advantage of proposing such a method.

    In recent years, companies are facing severe business competition. To survive and maintain continuous growth in this business environment, companies must establish sustainable business capabilities which can develop not only demand by developing markets, but also the supply capability to meet the demand. For Demand-to-Supply development, the business plan, which defines the direction of a company, has a critical role. The business plan, however, is a long-term plan, and is difficult to increase its accuracy because of the uncertainty during the term of the plan. This paper proposes a demand-to-supply development system for directing a sustainable business strategy, and presents a case study based on a beverage company. Namely, this paper proposes a management and evaluation system for a Demand-to-Supply strategy using dynamic capability management with a progressive curve. It makes a demand growth rate (β) plan and a supply growth rate (γ) plan based on a business scenario, which was made based on a long-term demand forecast. A Demand-to-Supply table is used to make a collaborative decision between the plans for βand γ. A Demand-to-Supply analysis is applied to analyze the gap between the current situation and the ideal situation evaluated by the optimal rate of capacity load (ρ^*) identified in the Demand-to-Supply table. The dynamically changing gap is evaluated and managed using a progressing curve.

    For the purpose of regional revitalization, new business creation and entrepreneurial business creation can be a viable approach due to the fact that entrepreneurship serves as a critical bridge between invention, innovation, and introduction of new products and services in the market. Recently, the recognition of social sciences as a factoring influence on regional revitalization in Japan is attracting the attention of many. It is said that the basis of the social revolution is brought by the knowledge derived from social sciences. Even though the importance of social sciences has been given attention, there has been limited research concerning the relationship between social sciences and innovation and management of technology among the businesses, especially research targeting university-based entrepreneurs. In this paper, we introduce a university-based students' business venture which does not utilize highly technical biological or engineering technologies, but applies a social science (knowledge creation) concept that enables them to combine both tacit and explicit knowledge to create necessary innovation and products, and to manage their technological needs.

    The Japanese Somushou (i.e., Ministry of Internal Affairs and Communications) announced, on Respect-for-the-Aged Day in September 2005, that the population of people over 65 is 25,560,000, or 20.0% of the nation's total population, which is the highest ever recorded in Japan. The Ministry also announced on June 1,2006 that the "special total birthrate" for 2005, indicating the average number of babies delivered by Japanese women, marked the lowest-ever level of 1.25. If the declining birthrate continues at a pace faster than estimated, the increasing ratio of the elderly in the nation's population will be far greater than expected. As new housing and large-scale supermarkets are being planned and built in the outer suburbs due to over-reliance on automobiles, the aged and needy who cannot drive for shopping are being forced into old inactive housing areas and shopping streets. People want to talk with each other as they get older, and advanced technology can help this. The following examples show two different shopping streets in Kyushu where shop owners and active elderly people still communicate with each other. In this paper, we recommend a cozy compact city where security and safety are assured, and the elderly can enjoy life and outside activities while being cared for in their homes.
