A decision support system is introduced for the efficient operation of port container terminals. It consists of ship planning subsystem, yard planning subsystem, resource management subsystem, real-time control subsystem, and simulation subsystem. The system is intended to support the planning process of the planners and the operation process of the administrators in the container terminals. It is assumed that the transfer cranes and the yard tractor/trailers are used to handle containers in the marshaling yard. The system is explained in terms of the functions of each subsystem and the data flows among various subsystems.

The rolling schedule procedure has been an important part of the Enterprise Resource Planning (ERP) systems. The performance of production planning in an ERP system depends on the selection of the three parameters in rolling schedule procedure: frozen interval, replanning interval, and planning horizon (forecast window). This research investigated, in a theoretical approach, the combined impact of selections of those three parameters. The proven mathematical theorems provided guidance to re-duction of instability (nervousness) and to seek the optimal balance between stability and responsiveness of ERP systems. Further the theorems are extended to incorporate the cost structure.

The primary role of MRP(Material Requirement Planning) is to make a production plan so that we have an exact quantity of right materials on needed time at right place. But the ignorance on capacity constraints makes some problems whenever production schedule is established. To increase the performance of MRP system, a novel approach which is based on new input data structure is suggested. The new input data structure includes all the information about Material BOM, Routing and resource data so that we can easily examine the usage of resources and generate higher performance production plans.

Construction project consists of several stages such as planning, design, construction, operation/maintain, etc. Decisions made in the planning and design stage have a significant impact on the construction and operation/maintain stages. Identifying key resources contributing to duration and cost of design alternatives is an important measure to achieve effective coordination between design and construction. This study proposes a method which finds an optimal design alternative by taking into account of resource planning, expected duration, and cost in construction stage. Base on literature review relative to the assessment of design alternatives, a method which predicts required resources, duration, and cost of the design alternative is established. Then, a method that identifies an optimal design alternative based on the preference of a certain project criteria is developed. Finally, a case study is presented.

Proper resource allocation is also a very important topic in power system problems, especially in operation and planning. One such is optimal maintenance problem in operation and planning. Least cost and highest reliability should be the subjects to be pursued. A probabilistic operation simulation model developed recently by authors is applied to the proboem of optimal maintenance scheduling. Three different methods are compared, marginal maintenance cost, levelized risk and maintenance space. The method by the marginal maintenance costs shows the least cost, the highest reliability and the highest maintenance outage rates. This latter characteristics may considerably influence the results of genetation planning, because the usual maintenance outages obtained from the other methods have shown to be lower.

The purpose of this research is to examine resource characteristics affecting the overall recreation suitability of natural recreation forest. On the basis of resource-based approach, we had constructed a conceptual framework for this research and found one dependent variable of the overall recreation suitability and eight independent variables, representing characteristics of recreation resource. After questionnaire surveying of 690 visitors from 10 among 72 natural recreation forests in Korea. We have analyzed the data using descriptive statistics, correlation analysis, and multiple linear regression method. We have found that 1) physical factor of recreation resources turned out to be statistically insignificant and the direction of relationship between independent variable and dependent variable is the same as that of dependent variable, 2) noise, sound and smell turned out to be the most important variable in terms of magnitude of independent variable and wild life turned out to be the next important variable, and 3) noise, sound and smell turned out to have aboutn 3.3 times greater thant that of landscape, judging from the absolute value of standardized regression coefficient. The research findings can be used for planning and designing of natural recreation forests based on recreation suitability of forest resources, and will provide pertinent guidelines for management of recreation resources of natural recreation forests. The approach and method of evaluating recreation suitability employed in this research provide us valid and reliable results and will be highly useful in other resource-based recreation development. We suggest that the differences in recreation suitability between private and public recreation forests and the relationship between user-satisfaction and recreation suitability of natural recreation forests must be examined in the future research.

This study not only suggests a methodology of science planning different from technology planning, but also applies the methodology to the case of astronomy and space science project. Throughout the analysis on this practice, we have provided logical tools for science project planning, and have identified a decision making process in science which has been regarded to be in a 'black box'. Therefore, this science planning technique can contribute to a more rationalized allocation of scientific resource at a project level as well as at a national level. In particular, catch-up countries in a transition to post catch-up stage such as Korea can establish a more efficient national R&D system by application of science planning concept to an emerging technology area.

The need for total enterprise management that covers from accepting orders, design, cost, procurement, manufacture, and delivery has been recently raised in order for efficient project management of small and medium size plant construction enterprises. This trend is reflected in the introduction of EPM(Enterprise Project Management) solutions by some shipbuilding enterprises and large construction corporations. In step with the trend, small and medium size plant construction enterprises are enabled to provide knowledge base in terms of reducing cost and production period and managing portfolio for accepting orders and attaining contract by inducing customized EPM This study presents a design of customized EPM based on a case study of a company. It exhibits a collaborative/collaboration resource-supply model which can be universally applied to small and medium size job-order production enterprises. The research discusses that under the assumption that information is shared internally between departments on planning, supply, manufacture, and quality control in order to create collaborative environment and close participation is created externally between suppliers and orderers, productivity can be improved in cost reduction through planning efficient collaborative supply model.

Organizations in some industries are still hesitant to adopt the Enterprise Resource Planning (ERP) system due to its high risk of failures. This study examined how industry classification affects the successful implementation of the ERP system. To achieve this goal, we reinvestigated the existing ERP Success Model that was developed by Chung with the data from various industry sectors, since Chung validated the model only in the engineering and construction industries. In order to test to see if the Chung model can be applicable outside the engineering and construction industries, the relationships between the ERP success indicators and the critical success factors in the Chung model and those in the sample data collected from ten different industry sectors were compared and investigated. The ten industry sectors were selected based on the Global Industry Classification Standard (GICS). We found that the impact of success factors on the success of implementing an ERP system varied across industry sectors. This means that the success of ERP system implementation can be industry-specific. Thus, industry classification should be considered as another factor to help IT decision makers or top-management avoid ERP system failures when they plan to implement a new ERP system.
