Vehicle Scheduling Problem (VSP) is a generic name given to a whole class of problems involving the visiting of "stations" by "vehicles," where a time is associated with each activity. The studies performed to date have the common feature of a single objective while satisfying a set of restrictions and known customer supplies or demands. However, VSPs may involve relevant multiple objectives and probabilistic supplies or demands at stations, creating multicriteria stochastic VSPs. This paper proposes a heuristic algorithm based on goal programming approach to schedule the most satisfactory vehicle routes of a bicriteria VSP with probabilistic supplies at stations. The two relevant objectives are the minimization of the expected travel distance of vehicles and the minimization of the due time violation for collection service at stations by vehicles. The algorithm developed consists of three major stages. In the first stage, an artificial capacity of vehicle is determined, on the basis of decision maker's subjective estimates. The second one clusters a set of stations into subsets by applying an efficient cluster method developed. In the third one, the stations in each subset are scheduled by applying an iterative goal programming heuristic procedure to each cluster.

Vietnams urban middle class is strongly value oriented in its shopping behavior. They want fairly good quality and service, but they also factor price into their considerations. In terms of retail patronage, they demand convenience, good service, attractive display, and especially want extensive choice. Brands must be present in multiple types of outlet, or fragile brand loyalties can be broken. Mini supermarkets have become an important part of the retail scene in the past decade, and have successfully introduced the supermarket concept to Vietnam. Many consumers are integrating mini supermarkets into their regular shopping, and are willing to pay the higher prices to gain the benefits of such shopping. However, the mini supermarkets do not adequately meet some of the things they expect from supermarkets. Large supermarkets are just entering the market, and are likely to capture much of the current mini supermarket customer base.

This paper presents a numerical approach to optimizing vehicle fuel economy in a higway bus. The method described is based on using a commercial software vehicle simulation to identify the relative efficiency of each of the vehicle systems, such as the engine hardware, engine software calibration, transmission, cooling system and ancillary drives. The simulation-based approach offers a detailed understanding of which vehicle systems are underperforming and by how much the vehicle fuel economy can be improved if those systems are brought up to best-in-class performance. In this way, the optimum vehicle fuel economy can be provided to the vehicle customer. A further benefit is that the simulation requires only a minimum number of vehicle testing for initial validation, with all subsequent field test cycles performed in software, thereby reducing development time and cost for the manufacturer.

This study is to apply of AHP to the performance management of university organization. Especially, in the present study, the authors modeled performance evaluations for S university administration hierarchically and analyzed the weights of those. The domains of performance evaluations were divided in five domains: strategy, resource management, process, finance management, and customer management, referred to the viewpoints of BSC. The results of analysis revealed that strategy was the most important element of evaluation in the first stage and except for strategy and finance management which consist of the single element of evaluation respectively in the second stage, the efficiency of administration supporting service was the important element of evaluation. The weights of performance evaluations, however, revealed in different as the class of position. Finally this study showed that the weights of performance evaluations computed in the present study can be used as those of evaluation indices for S university administration.

We developed a similar product recommendation system for implementing a collaborative commerce model between the cooperating companies. The system is based on a similar product finding algorithm. The main idea of the proposed algorithm is using a multi-attribute decision making(MADM) to find the utility values of products in same product class of the companies. Based on the values we determine what products are similar. The system helps the companies to recommend products in accordance with the customer's preferences regarding product specifications.

From the definition of the cruise ship mission based on the investigation of the customer needs and statistical estimates and to design of the residence area of the cruise ship, in this study a conceptual design of the traditional ship parts (the lower hull) was carried out. for the light weight estimation of the cruise ship, several methods that have been used for commercial ships were evaluated to adapt for the cruise ship, the main particulars of the ship were determined with the light weight estimation and the assumed dead weight. From these main particulars of the ship, the hull form was developed with CFD verification and the general arrangement for the lower hull was achieved. For several loading conditions the intact stability of ship was checked.

The objective in this paper is to develope the e-Supply Chain Management System and applied for the Manufacturing. A Manufacturing that is consider to be world class recognize that its ability to complete in the marketplace depends on developing e-SCM System that is properly align with its mission of serving the customer. This paper investigated the relationship between e-SCM and performance in manufacturing. A stratified random sample was collected from the Federation of Korea Industries. Conclusively, e-SCM is important factor between source factors (environmental dynamic, Leadership) and manufacturing performance. e-SCM is significantly related to Quality, Flexibility, Delivery, and Cost.

Models of single-server queues with vacations have been widely used to study the performance of many computer communi-cation and production systems. In this paper we analyze an M/G/1 queue with generalized vacations and exhaustive service. This sys-tem has been shown to possess a stochastic decomposition property. That is the customer waiting time in this system is distributed as the sum of the waiting time in a regular M/G/1 queue with no va-cations and the additional delay due to vacations. Herein a general formula for the additional delay is derived for a wide class of vacation policies. The formula is also extended to cases with multiple types of vacations. Using these new formulas existing results for certain vacation models are easily re-derived and unified.

This study intend to make easy modification, even if there is a new job or structure change, by modularizing program and computerize and automation of production control management used in CIM. Under the condition where manager control production on the job-site, for increasing connection with other operation and management on the computer by monitoring center computer, Recognizing information by computer is needed, it is possible by converting transaction. So production increase and quality improvement are possible by diminishing manager's and producer's work with the result of the study combining POP and CIM, after that, in e-business and m-business period that every enterprise must pass, customer satisfaction and sales promotion are possible with employee's computerizing minds. These study result also can knowledge process condition with theoretical class and have a power in finding a solution with foundation of theoretical knowledge.
