The importance of project performance management as an alternative for solving problems is rising, which are followed by the hardships of managing construction project in the construction industry. This research classifies and applies the improvements made by the operator's work, in order to apply factors of success on the construction project, as performance management factors. In addition, in order to predict the results reflecting the project characteristic of performance management factor un-improvable by the operator in the initial stage of construction, the effect of project characteristic to the performance was drawn by performance difficulty. Also, in order to improve the predicted performance, researches on setting valid best practices according to the performance territory through a correlation analysis between the best practices improvable through the operator's work, and the performance was made.

Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

The purpose of this thesis is to analyze and evaluate issues and performance of development projects of Gurye Banggwang villages' key projects, especially directly or indirectly related to resident income augmentation. The agricultural products processing factory, the valley resting, the urban and rural exchange center, and the village festival have been closely selected as directly or indirectly related to the resident income. Analysis of survey of resident and two agriculture unions' members led the performance and problem of Banggwang villages' development projects. The income project has the difficulties of recruiting members, lack of professionalism of people in production and marketing of processed products, and conflict between members etc. For this reason, income projects being adopted as the comprehensive rural village development project is often negative. Compare to the other cases, Banggwang village has more reflection of the income project, and has lot of interest by policy makers whether it be pursued successfully. It is too early to evaluate a performance properly because it is the beginning of income projects and the experience are not yet being sufficient. However, the performance is appearing gradually from various sides. For example, dividend of business profits, employment opportunities and sales of agricultural products are developing increasingly. Income projects have strengthens the residents' participation and interest in comprehensive rural village development project and with securing stable funding it will help to maintain the facilities.

Project Management Information System (PMIS) is a special purpose information system that is created to provide useful information for project managers and participants to make effective and efficient decision making during projects. The use of PMIS is increasing in project based industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project management performance. However, it is unclear what are the difference of PMIS impacts between industries, and still need to be studied further. The purpose of this study is to compare the impact of PMIS on project management performance between industries. We assume that the effects of PMIS will be different depending on the industry types. Five hypotheses are established and tested by using statistical methods. Data were collected by using a survey questionnaire from those people who had experience of using PMIS in various project related industries such as construction, defense, manufacturing, software development and telecommunication. The survey questionnaire consists of 5 point scale items and were distributed through e-mails and google drive network. A total of 181 responses were collected, and 137 were used for analysis after excluding those responses with missing items. Statistical techniques such as factor analysis and multiple regression are used to analyze the data. Summarizing the results, it is found that the impacts of PMIS quality on the PM performance are different depending on the industry types where PMIS is used. System quality seems to be more important for improving the PM performance in construction industry while information quality seems more important for manufacturing industry. As for the ICT and R&D industries, PMIS seems to have relatively lesser impact compared to construction and manufacturing industries.

The purpose of this study is to estimate the perception of elderly residents on the residential environment improving projects and suggest the political implications. The survey include questionnaires about the importance and the satisfaction level on the project maintenance factors. The results were statistically analyzed by Importance-Performance Analysis (IPA). As the result of the study, firstly, it shows that 'the possible overkill area' on the IPA action grid includes none of factors except 'landscape' which is very similar to mean of performance score. the result of analysis means that the project is very efficient. Secondly, the policy is necessary to improve 'pedestrian passage', 'public open space' and 'transportation environment'. Considering elderly residents especially 'pedestrian passage' and 'public open space' are in need of improvement immediately. In detail 'traffic facility', building 'urban park' and 'pedestrian passage', 'paving of pedestrian passage', 'children's playground' are in need of improvement as well. The results of analysis on elderly and non-elderly residents of Yonnam project may be important foundation for future strategies for improvement.

This study is intended to look into the structural relationships between project manager's creative thinking, entrepreneurship, and project performance. To achieve this, research model and hypothesis were established to carry out statistical analysis based on the results of an empirical sample survey. The findings showed that project manager's creative thinking didn't improve project satisfaction directly, but it improved project satisfaction through the mediating effects of project manager's entrepreneurship. While it had a direct effect on perceived project performance, project manager's entrepreneurship was not mediated in this process. This suggests that even if project managers have a high expertise, thinking skill and motivation as creative thinking in working on the project, they have the limitation in leading to customer satisfaction from a personal perspective.

Overseas construction projects tend to be more complex than domestic projects, being exposed to more external risks, such as politics, economy, society, and culture, as well as more internal risks from the project itself. It is crucial to have an early understanding of the project condition, in order to be well prepared in various phases of the project. This study compares a structural equation model and multiple regression analysis, in their capacity to predict cost performance of international construction projects. The structural equation model shows a more accurate prediction of cost performance than does regression analysis, due to its intrinsic capability of considering various cost factors in a systematic way.

The slowdown of the global economic market due to the pandemic is causing the global construction market to stagnate, and the use of smart construction technology is drawing attention as one of the main alternatives to overcome this problem. In fact, a number of previous studies have been published that smart construction technologies such as building information modeling and drones can contribute to project performance improvement, such as productivity improvement and cost reduction. However, previous studies focus on the application direction and technical effectiveness of smart construction technology, so the analysis in terms of the contribution that the application of the technology has to the project performance is insufficient. Therefore, the purpose of this study is to focus on the effectiveness aspect of the application of smart construction technology on the project performance. The results of this study are expected to be able to be used as basic data for establishing policies related to the activation of smart construction technology promoted by the government and setting the direction for the use of smart construction technology by stakeholders.

This paper presents a new method for forecasting construction project cost and time at completion or at any intermediate time horizon of the project duration. The method is designed to overcome identified limitations of current applications of earned value method in forecasting project cost and time. The proposed method usesfuzzy set theory to model uncertainties associated with project performance and it integrates the earned value technique and the contractors' judgement. The fuzzy set theory is applied as an alternative approach to deterministic and probabilistic methods. Using fuzzy set theory allows contractors to: (1) perform risk analysis for different scenarios of project performance indices, and (2) perform different scenarios expressing vagueness and imprecision of forecasted project cost and time using a set of measures and indices. Unlike the current applications of Earned Value Method(EVM), The proposed method has a numberof interesting features: (1) integrating contractors' judgement in forecasting project performance; (2) enabling contractors to evaluate the risk associated with cost overrun in much simpler method comparing with that of simulation, and (3) accounting for uncertainties involved in the forecasting project cost.
