The purpose of this study is to suggest Process Reference Model(PRM) for BIM/GIS-based Energy Information Modeling(BG-EIM) efficiently. Through the study, the detail process and consideration were derived to design EIM for the purpose of energy analysis depending on specific use-cases. To do this, we survey related studies and analyze the detailed EIM process. By using the results, BIM/GIS-based energy analysis consideration is defined and BG-EIM PRM is proposed.

The processes for verification of performance records in construction have many problems according to construction firm's participating in some of the processes. This study analyzed about current processes and provided improved processes with IDEF method. As the result of this study, it was found that 'As-Is' model has many repetition of activities and 'To-Be' model has three times more effective than 'As-Is' model has. The data modeling which is available for 'To-Be' model was also suggested.

To reduce uncertainties and make rational plans, the presumption of contingency against a failure of projects and an occurrence of unpredictable risks is important with accurate estimations as the work progressing. Therefore, if the presumption of contingency reflecting uncertainties carries out at a decision making point of time, be able to prepare for risks. The purpose of this paper is to present a management process of contingency through the performance analysis of project. In the cost planning phase, this study offers a process which is predictable contingency and predicts the range of fluctuation of the cost, laking an advantage of EVM in construction phase. With reflecting the results from this procedure, this study presents a process, rationally manageable contingency.

Over the last two decades, national R&D projects have been increased rapidly. The government has tried to improve the success of national R&D projects. But the weakness of the evaluation process for national R&D projects, there remains some problems. In order to solve those problems this study proposed an advanced evaluation process of national R&D projects on the basis of ISO/IEC15288, ISO/IEC12207 and ISO/IEC14598. The evaluation process consists of preparing evaluation, establishing evaluation requirements, specifying evaluation, designing evaluation, executing evaluation and reporting evaluation. The evaluation process is an artifact-oriented process. The results of this study can be used for reforming the evaluation process of national R&D projects.

The purpose of this paper is to propose a method for business process system (BPS) based on the Internet of Things (IoT). As the results of this research the IoT architecture and the business process design are derived. The main findings include the proposed IoT-enabled BPS method, illustrated by the description of the application and its assessment. In addition, the key business processes namely; remote machine monitoring; maintenance of machine; material procurement; product pricing; and information reporting system, are affected by IoT technology. The proposed method of this research could be the reference for the companies which want to have better management performance based on IoT technologies.

This research focuses on the process improvement of port logistics by using Lean methodology. On the one hand, we firstly analyze the current situation and weakness of the processes in port logistics, and then re-design the current processes by the principles of Lean discipline. Based on the appropriately changed processes, the improvement scheme of port logistics will be figured out. On the other hand, we construct the port logistics system by implementing the improved processes. The port logistics' processes accomplished in steel company will be further assorted and identified. The relationship of wharves process, operational process, shipping process, construction process, quality process, and purchasing process are also defined. Every process has been improved by Lean Tools in order to analyze the value added or non-value added processes, to improve the service level, and to reduce the cycle time, inventory, changing time, re-working and waste. Based on above, the appropriate environment that is suitable to Lean process of port logistics will be established and the modeling that can help to implement the improvement scheme will be figured out.

The construction industry concentrates their efforts on construction information technology (IT) including construction CALS. However, the actual circumstances for construction IT focuses on building hardware and it neglects importance of business process reengineering (BPR) for construction tasks. A systematic process modeling method and a computerized model by process concept need for building construction BPR. This study develops a generalized BPR procedure for construction projects, and then suggests a new process modeling method for construction BPR that consists of object-related process model (ORPM). Finally, this study develops a web-based ORPM Builder (ORPMB) based on the ORPM methodology, and the applicability of the developed system is verified by a case study with practical construction processes.

For parallel implementations of functional programs without concurrent primitives, the λ-calculus encodings have been introduced. A functional program may be trans for med into a process network using process calculiby the λ-calculus encoding and there sult of a program can be obtained by a deal of communication actions in it's process network. But the λ-calculus encodings cause too many communication actions even in constant expressions. This paper shows the encoding for a combinator program without concurrency primitives which can combine the graph reduction and the process-net reduction using computable processes,'chores'. A 'chore' may have graph reduction functions for primitive operations of constants for which local graph reduction may be possible, and be encoded from a 'G-reducible' subexpression which is obtained by an annotation and trans for mati-on for a combinator program, assuring that it does not include any combinator application. Also, we show that a process network with chores raises less commu-nication actions than one without chores.

The Indian Buffet Process is a stochastic process on equivalence classes of binary matrices having finite rows and infinite columns. The Indian Buffet Process can be imposed as the prior distribution on the binary matrix in an infinite feature model. We describe the derivation of the Indian buffet process from a finite feature model, and briefly explain the relation between the Indian buffet process and the beta process. Using a Gaussian linear model, we describe three algorithms: Gibbs sampling algorithm, Stick-breaking algorithm and variational method, with application for finding features in image data. We also illustrate the use of the Indian Buffet Process in various type of analysis such as dyadic data analysis, network data analysis and independent component analysis.

We propose the design of the warfighting experiment process for software intensive systems using the intelligent maturity model and suggest the application results of the target searching capability in smart UAV. For this, we design the intelligent maturity model to evaluate the intelligent degree of the software intensive systems considering the domain and intelligent level. Then we classify the IS0/1EC-12207 process and CMMI process as LITO domain for designing the warfighting experiment process, map the classifed process to the five factors of the warfighting experiment and derive the process as warfighting experiment element and phase. Based on the derived process, we design the warfighting experiment process using the IDEF0. Finally we apply the proposed process to the target search capability and suggest the results which are required to develop and acquire the smart UAV.
