  • In the past, several construction projects have exceeded their schedule resulting in financial losses to the owners; at present there are very few methods available to accurately forecast the completion date of a project. These nay be because of unforeseen outcomes that cannot be accounted for earlier and because of deficiency of proper tools to forecast completion date of said project. To overcome these difficulties, project managers may need a tool to predict the completion date at the early stage of project development. Bayesian Inference introduced in this paper is one such tool that can be employed to forecast project progress at all construction stages. Using this inference, project managers can combine an initially planned project progress (growth curve) with reported information from ongoing projects during the development, and in addition, dynamically revise this initial plan and quantify the uncertainty of completion date. This study introduces a theoretical model and proposes a mathematically information-based framework to forecast a project completion date that corresponds with the actual progress data and to monitor the modified uncertainties using Bayesian Inference.

  • This study estimated direct factors that have effect to completion degree of game, and we constructs structural equation model that can evaluate completion degree of game using empirical analysis. For it, we obtained weight of components of game development by eigenvector method for analytic hierarchy process. Using calculated weight, we also let that components of game development is observating variable of X, and genre of game is observating variable of Y. And we constructs structural equation model with LISREL program

  • In the process of complex shopping mall development, all the steps (business planning step, pre-sale & completion step, management & operations step) head towards a consistent ultimate goal in an overall business perspective. In this study, we analyze using a structural equation model if an appropriate relations between each of the steps are formed to achieve the ultimate goal. In this study, we find a positive relationship between business planning step and pre-sale & completion step, and also find that for success pre-sale & completion, a faithful business plan is necessary. But we find no statistically significant relationship under significant level 0.05 among business planning step and management & operations step and the level of success, pre-sale & completion step and management & operations step and the level of success, management & operations step and the level of success. This suggests that each of the steps does not form a close relationship to achieve the consistent goal in the complex shopping mall development and each one is doing a short-sighted work for its own profit.

  • In real software development fields, software is unified by several modules that are developed before the software testing period. For the evaluation of software task processing performance, this paper considers the software imperfect debugging model that is proposed by Lee and Park (2003) and presents the measures of a unified software, such as the completion probability of a task which is completed in a time interval and the expected number of the completed tasks. In addition, we suggest a software release policy that satisfies the required level of the expected perfect debugging, completion probability, and availability.

  • Despite a recent increased nation's attention given to improving end-life care, we professionals need to be more critical and reflective on our realities surrounding hospice palliative care. The aim of this paper is to suggest that palliative care models can be used for patients/families in the last phase of life and examine whether they are appropriate for caring them in congruence with philosophy of hospice. The hospice experience model (HEM) of Eagan & Labyak and the developmental model of Byock are introduced and examined for their congruence with philosophy of hospice in applying to clinical practice. The HEM as a patient/family value-directed end of life care model emphasizes three principles; unique experience of patient/family, interactions/relationships among multiple dimensions of personhood and between family, and personal growth and development in the face of suffering through a life-completion. The developmental model stipulates dying as the last stage of living, a stage of life cycle in which patients/family may have growth through life-completion in multidimensional relationships of personhood. The model includes the developmental landmarks and tasks for life-completion as the framework to guide a means of professionals' to recognize their opportunity to grow. The landmarks and tasks include worldly and social affair, individual relationships, intrapersonal, and transcendent dimension. The models could work as appropriate palliative care models for patients/families in the last stage of living. The professionals need to be encouraged to apply the models to end of life care setting.

  • Modules that consist of software are respectively coded in the early development phase and the modules are unified as a software. After unification, the software is repeatedly tested with a given taskset (the set of module tasks that are tested simultaneously) until a required performance level is satisfied. In this paper, we expand the one-module software debugging model of Jang and Lee (2011) to a multi-module debugging model and derive the taskset completion probability and the mean of the completed tasksets under the assumption that the processing times of module tasks given in a taskset are mutually dependent.

  • As the software complexity increases, the development success rate decreases and failure rate increases exponentially. The failure rate related to the software size can be described by a growth function. Based on this phenomenon, this paper estimates the development success and completion rate using the Gompertz growth function. At first, we transformed a software size of numerically suggested $10^n$ into a logarithm and kept the data interval constantly. We tried to derive a functional relationship between the development success rate and the completion rate according to the change of logarithmic software size. However, we could not find a function which can represent this relationship. Therefore, we introduced the failure rate and the cancel rate which are inverse to the development success rate and completion rate, respectively. Then, we indicated the relation between development failure rate and cancel rate based on the change of software size, as a type of growth function. Finally, as we made the Gompertz growth function with the function which describes the cancel rate and the failure rate properly. We could express the actual data suitably. When you apply the growth function model that I suggested, you will be able to get the success rate and completion rate of particular site of software very accurately.

  • This paper describes a project - based quality management model that identifies development technologies and codes while at the same time verifying the ability to implement processes that are essential in R & D projects. In order to verify the process implemented in the R & D project implementation, there are review, checking points, and evaluating methods the process performance levels for five processes such as defining requirements which is the beginning stage of system development, testing process which is the completion stage of system development, and project management and peer review process for project management and support in the proposed project-based quality management model. For development technology and code validation, the model included the documented test cases for each requirement by the developer in the requirements definition stage, debugging and testing in the design and implementation stages, static analysis and open source licence verification procedure, and system environment. After applying the model in SW development R&D project for evaluating the process performance, and verifying the development technology and the code, the developers responded that the improvement in the development technique and the code, and upgrade of process performance level for project are more than 10%.
