This paper proposes an integrated SE process for the development of railway systems with safety assessment included. Although the safety assessment process must be performed with SE process properly with good coordination, the interfaces between the two processes have not been clear. Thus, in many of safety critical system developments in Korea, it is difficult to assess safety in proper development phase. The process model proposed in this paper is based on both the concept of system life cycle and the repetitive use of SE process. In each of development phases, appropriate safety assessment methods are described. Also the evaluation of the integrated system incorporating safety factors is described. The resultant process model is expressed by the Enhanced Functional Flow Block Diagram (EFFBD) using a CASE tool. The model also allows timeline analysis for identifying activity flow and data flow, resulting in the effective management of process. In conclusion, the integrated process enable both the SE process and safety assessment process to cooperate with each other from early development phase throughout the whole system life cycle.

Recently, the strategy of the age of limitless competition for existence of manufacturing company appears for the enhancement of productivity through the automatic system, the reduction for the cost for standardization and the decision making process for the information system. Especially the critical success factors in manufacturing company can be summarized for the establishment of production visibility through the production management, material & work-in-process management, the establish of the flexible manufacturing system for the changed order priority and the establish of the quality system for improvement of product and process quality. The existing production management systems supply only simple information about production results on real time, can delay quick decision making. And it can prevent acquiring the information about various customer needs and the communication problems with other systems. In this paper, it will show MES system, a solution for the problems of existing production management systems. And through a case study of D company, it will reveal improvement effect on shipment error using MES system and economic analysis for MES itself.

Construction accidents occur reiteratively in similar fashions. There have been several attempts to develop a safety program for preventing construction accidents on sites. It will be very effective to use previous accident cases for establishing proper safety plan and managing safety process. This research develops a case-based construction safety management system which enables construction managers or safety managers to prevent potential accidents during the construction process. The case-oriented approach is performed through the representation of previous accident cases in accordant with the similarity to the conditions of current site. It uses a case-based reasoning which is one of the reasoning methods of an expert system. A prototype system for the reasoning model was implemented using one of the case based system development tools. The system was applied to a real construction site to verify its capability and validity. It was founded that the causes of accidents were successfully removed, so the proposed model proved to be reasonable. Additional research is needed to resolve the technical problem how to adapt the countermeasures for accident prevention provided by the reasoning model.

Assignable causes producing temporary deviation from the underlying system can influence on process adjustment and process monitoring in dynamic feedback control system. In this paper, the influence of assignable causes on EWMA forecasts and compensatory variables are derived for a dynamic feedback control system. An example is presented to confirm the impact numerically through the analysis of a data.

This paper presents integrated control and safety management system for a LNG storage tank. This system is for collecting and analyzing the temperature, pressure, and vibration signals in which are used to control and guarantee the system safety and leakage control from the inner gas tank. Based on the investigations of LNG tank related failures and accidents, we strongly recommend the modification and new development of current safety related measuring and control systems because the LNG tank is constructed bigger and bigger in recent years for the efficiency and safety increments. Thus, this paper presents newly developed integrated control and safety management system for a large LNG storage tank. This system provides the enhanced measuring and control systems, and new displacement based safety system, which may detect and control the deformation properties of tank structures. In addition, we recommend that the new integrated control and safety management system should be coupled by process integrated innovation system (PIIS) for an increased safety, efficiency, and productivity of LNG tanks.

In the field of domestic construction demolition works, work process management system is left behind compared with that of several advanced countries such as US, Japan and UK. Especially, the problems regarding safety management are more serious in terms of the availability of safety manuals and law system. The analysis results fiom the questionnaire survey and interviews with demolition engineers indicated that current safety management practices in demolition works lack systematic approach and inappropriate in securing labors' safe working environment. In addition, field labors and managers strongly requested the improvement of safety educational system. Grounded upon the analyses results and investigations, suggestions were drawn for the establishment of advanced safety educational system.

In developed countries, the number of accidents has significantly decreased with the introduction of the process safety management system, but it has a regulatory nature and it is difficult to show the actual situation of workplace safety management. Many organizations recommend the use of process safety performance indicators to comprehensively monitor process safety status. In this study, for the application of process safety performance indicators, the related guidelines were compared and analyzed, and the method of using the process safety system of the workplace as an indicator was reviewed. In literature indicators, compliance with procedures is mainly checked, whereas in system-based indicators, procedures or inspections for a specific purpose of the safety system can be clearly identified, and the operation status can be measured and monitored. It can be seen that this characteristic is more advantageous in terms of the clarity of the supplements derived in operating safety management activities. Using this, it is possible to effectively show the level of safety management in the workplace.
