In logistics industry, long-distance transportation at night is currently employed. But,to deal with the increase in the number of buggages, they need to introduce the operation aroundthe clock in order to shorten the delivery time. This paper quantitatively investigates what arethe possible issues and the solutions for them by simulation approach. The main ndings are asfollows: First, the delivery around the clock is much more costly than that at night. Second, byintroducing "gateway" among several bases, which can consolidate the baggages in local at rstand then transport them to the other regions, shorter delivery time and lower delivery cost havebeen observed.

The database "Nikkei supermarket POS data" contains the daily sales data which are collectedfrom about 300 supermarkets in Japan. Using this database, wefind a power-law correlationbetween the number of products and sales of supermarkets. This means that sales of supermarketsbecome larger not linearly but in power law as the number of products increase. Furthermore,we observe that the power-law exponent does not change largely over the last 10 years. Thiscorrelation is, therefore, thought to be an universal law.

In a factory of the supply chain, it must be improved benefits while responding to a demanding request from customer. Therefore, planning and warehouse department has developed a reduction method of the stock and ordering cost, and the manufacturing department has developed a scheduling method to minimize the delay in delivery and cost. However, since these methods are implemented in each department, the entire factory may not satisfy the customer's request.This study builds operational simulation model of the entire factory by consolidating each department. Using the model, we reveal the threshold of the stock and manufacturing cost that meet the customer's request.

After the 1991 land price bubble collapse, many statutory redevelopment projects had been forced not to complete by mainly the shrink of the floor demands or the difficulty of the floor demand forecasts. Then, the 'appropriate size' redevelopment style was advocated that prefers the matching the areal floor demands to intensive landuse and that emphasizes the delay costs by the project period. This style can be interpreted as reduction of the business profitability risk. The purpose of this article is first to report Nayabashi East project as thistypical case, to explain the effects on the risk management of the 'appropriate size' and to illustrate the effects through Monte Carlo risk simulations of a simplified model.As the results, we conclude that this project had succeeded to get out of the red by the change of urban planning decision. We also refer on an artificial society approach as its further work.

How different urban properties (such as number of hospitals, shops, patents, andcrimes) depend on city size? It has been demonstrated that most urban propertiesYfollow theallometric scaling lawY/N, whereNandare population size of a city and the scalingexponent. Urban infrastructure has been shown to scale sub-linearly ( <1) re ecting large citiesdon't need large infrastructure, whereas output and income have been shown to scale super-linearly( >1) re ecting high per capita in large cities. We empirically analyze urban scaling observed inJapanese telephone directory data. This data are renewed every 4 months, offering comprehensivelatest address info on nearly all shops, rms, hospitals, schools, parks, etc on a nationwide scale.These urban properties are divided into 332 categories depending on the urban role. This allows usto study and discuss systematically the scaling exponent that are associated with various aspects ofurban properties. We show that obtained scaling exponents help to characterize urban properties.

The purpose of this study is to (1)make clear the situation and structure of performance among Start-Up Firms in Japan,(2)investigate the relationships between performance and external support to them. We analyzed the questionnaire research on the basis of the answers which were obtained from 2,897(1stresearch)people of Start-Up's. As a result of factor analysis ,4 main factors :"business quality/management posture","external support","quantitative performance","qualitative performance"were extracted. Among the 4 factors,we admit some significant relations ,but "qualitative performance"did not show significant relations positively to any of the three remaining factors.

In this paper, weapply gamification to senior for fitness habits. But, whenthe senior play the game some problem is encountered. We concentrate on the issue thatthe senior don't understand how to deal with the game system. The senior recognizethe method for rearing pet.We propose a gamification expressed the method for rearingdog, therefore the senior utilize this light to playing game. Weconducted experiment. Proposedgamification is effective for workingmotivation, understanding of how to playthe game and aggressiveness against playing the game.

Manga case method based on a narrative approach is effective way to learn practical knowledge. We propose a method for development of Manga text with a conjoint method and analysis of present state tree. Especially, we develop two type stories based on the result of conjoint method. They enable us to face with a dilemma in Manga text. We evaluated them based on Kirkpatrick evaluation model. As a result, developed Manga text bringlearners' actions for disaster defense.

Understanding behavioral characteristic in the evacuation drill is important to develop an effective way. In the first experiment, we confirm the position of sensor to measure accurately. In the second experiment, we take a maze experiment and confirm validity. In the third experiment, we analyze the evacuation activities by comparing sensor data with video data.As a result, we can identify a part of characteristic behavior.
