  • Slow-moving items whose cost is so high and/or whose demand is so low the optimal policy is to place a reorder immediately whenever a demand occurs. This is a continuous review (S-1,S) inventory policy which means that whenever a demand for an arbitrary number of units is accepted, a reorder is placed immediately for that number of units. This paper show optimal inventory level ($S^*$) when arrivals tend to get discouraged and recommend practical difficulties of deciding stockholding policy of slow-moving items. Also, a simple numerical example is provided.

  • This thesis compares life test acceptance sampling plans under lifetime has an exponential distribution. Various practical considerations may lead a user adopt a two-stage, or double sampling, test procedure. Hewett and Spurrier(1983) provided a survey of two-stage methods, as well as examples of experiments for which a two-stage procedure would be appropriate. The plans are compared in terms of the expected number of failures, and the expected time required to reach a dicision. Computational experiments are conducted and the results are tabulated to provide guidelines for selecting an appropriate plan for a given situation.

  • This article describes a prototype expert system for yarn spinning process planning in textile industry. This expert system is intended as a consultant to give the technicians interactive assistance for the appropriate process planning in accordance with used materials, required count, and other factors affected yarn spinning by means of many types of machine. Also, this system has the other function that can be compared the standard values with the measured ones for quality characteristics control. VP-EXPERT-a rule-based microcomputer expert system development tool-provides the expert system components for this development. The details of knowledge organization, rule representation, inference reasoning process, and performance of this expert system are demonstrated with the practical yarn spinning operations.

  • Service Oriented Architecture(SOA) is an enterprise-scale IT architecture for linking software resources available on the network. SOA is believed to become the future enterprise solution that promises the agility and flexibility by integrating business processes through composition of the software services across enterprises. The first step for SOA construction is to identify the services. In this paper, we present a process-based service identification methodology for SOA through a case study of an IT company. Our methodology is composed of three steps: Processes (business & technical processes) analysis and systems analysis, Service candidates selection, and Service evaluation and construction planning. This framework would be practical and could be accepted to other organizations as it has been developed through the real case.

  • From fast service enlargement of the latest economy and industry, importance of service industry is embossed gradually. Service enterprise is pushing on in service quality elevation for strengthening competitiveness to survive on globalization society as manufacturing industry. Service quality elevation adapts as core competitive strategy in enterprise with business environment as continuous competitive advantage. Because Public organization also is developed in service fast, Public organization is trying to offer various service such as service level of enterprise. Each Public organization are trying to satisfy request of citizens as Customer. In this study, presented Kano-Servqual Method which is mixed by Kano's and Servqual model's advantage, each Method had used much in service quality measurement separately. Kano-Servqual Method is applied to the A information library as a public organization and is proved as practical useful method.

  • Physiotherapy has recently become an essential part of enhanced recovery protocols after thoracic surgery. The evidence-based practice of physiotherapy is essential for the effective management of postoperative patients. Unfortunately, only a small body of literature has discussed the rationale of the physiotherapy interventions that are routinely implemented following thoracic surgery. Nonetheless, we can integrate the available knowledge into our practice until new evidence emerges. Therefore, in this review, the principles of physiotherapy after thoracic surgery are presented, along with a detailed description of physiotherapy interventions, with the goals of enhancing the knowledge and practical skills of physiotherapists in postoperative care units and helping them to re-evaluate and justify their traditional practices.

  • The Industrial development and the Increase in population have brought out a rapid increase of wastewater discharge. To deal with this matter, much estimate has been spend on construction and management of a large scale sewage treatment plant. Although every effort has been carried out, river water quality has no significantly improved. Especially. the aggravation of the water quality in dry season is brought out a serious social problem. The purpose of this study Is the development of an optimal water quality management technique considering the efficient control of the multiple pollutant load associated with the total pollutant load control. A GUI(Graphical User Interface) system named 'QL2-XP' model is developed by object-oriencted language for the user convenience and practical usage. Suggested GUI system consist of hydraulic analysis. water quality analysis, optimized model calibration processes, and postprocessing the simulation results.

  • Brebbia's model has been analyzed to develop the appropriate waterworks management system in Korea, and compared with the conventional models such as EPANET, WaterCad, and InfoWorks. The hydraulic theory of the models was analyzed. Each model's numerical techniques, required parameters, input data and operational methodologies, restrictions, practical applicability and other aspects were investigated. In order to check the validity of Brebbia model, the comparative analysis with EPANET, WaterCAD, and InfoWorks models was performed for linear and nonlinear cases. To find out advantages and disadvantages of each model, the modeling was performed for a simple network and for more complicated A city waterworks system, and the three models applicability was examined. Finally, optimal modeling technique and a model suitable for the use in Korea was suggested, and the problems related to present projects of waterworks management system in Korea were analyzed.
