  • VE is one of the technologies that are essential to promote cost reduction and performance improvement in construction projects. In the VE process, there are very important steps in deciding whether to adopt VE ideas and alternatives or not. However, when examining the possibility of selecting and adopting alternatives, it is difficult to clarify the differences and characteristics of the existing and improved proposals due to lack of understanding of the owner and inadequate consideration of harmonization with the alternative surroundings. In order to overcome these problems, it is necessary to effectively exchange information related to alternatives among VE participants and to examine the applicability of VE alternatives more in-depth. Therefore, in this study, a process for reviewing the applicability of VE Alternatives using BIM based VR was proposed to review more appropriate VE alternatives.

  • The purpose of this study was to identify the general characteristics of test subjects in association with three planned housing alternatives in different focus level of work opportunities, leisure activities and services. Subjects used in the study were people in their 50's who were surveyed in 2002. A total of 464 subjects were selected from 556 samples. Statistical significance was found between the preferred housing alternatives and the subjects' background including education level of the subjects and their spouses, monthly income, assets, subjective economic capabilities, and housing size. However, there was no statistically significant differences in recognition of housing problems for later life among groups. Groups selecting different planned housing alternatives showed statistically significant differences for some features of the senior housing. From these results, it is proposed that various designs based on the levels of work opportunities, leisure activities, and services for the senior housing should be provided to satisfy the demands.

  • This study is concerned with the reduction of fraction defective for quality improvement model in manufacturing system. For the methodology, a heuristic method for the selection of alternatives of process improvement is introduced for quality improvement and cost problem subject to cost constraints. This study suggests a model for selecting fraction defective reduction alternatives in multi-stage manufacturing system and a numerical example is presented.

  • The Analytic Hierarchy Process(AHP) model developed by Saaty is a very useful decision-making model designed for selecting and evaluating project alternatives through $\ulcorner$pairwise comparison$\lrcorner$ in the context of hierarchical structure. In this paper, we construct a modified AHP model named Analytic Dicho-Hierarchy Process (ADHP) model necessary for evaluating technology alternatives.

  • This study is aimed to design a priority setting algorithm necessary for evaluating and selecting interdependent R&D planning system alternatives. In case that the relationship of technology alternatives is interdependent, a relative importance as occurrence or nonoccurrence of the technology alternatives viewed from the future time varies. So, we are subject to design the evaluation process considering a cross- impact of future technology alternatives. Thus, we apply the cross impact analysis (CIA) model to consider the cross-impact among interdependent system alternatives. Also, the analytic hierarchy process(AHP) model is applied to determine the priority of alternatives by taking the pair-wise comparison among factors.

  • The object of this research is to evaluate the priority of R&B project alternatives which were already screened by both feasibility and suitability of technological performance. This research is a selection model for R&D project alternatives after setting phase. And it is designed by CHP model which include individual and mutual weights. This model have 5 steps. (1) Setting Technology-Modules derived on the setting phase (2) Presenting the evaluation standards divided with 'M-Field' and 'T-Field' (3) Assessing the evaluation standard and technology modules (4) Obtaining and integrating the individually and mutually effective weights (5) Selecting the technology modules based on the priority of order by CHP. Through these steps, this model can suggest the evaluation way from specific technology levels to project level. And it can be guaranteed to perform the selected module set.

  • The purpose of this paper is to propose an interactive method using the concept of Signal­to­Noise (SN) ratios and cutting ranges for selecting the most preferred alternatives of Multiple­attribute Decision­Making(MADM) with the­smaller­the­better or the­larger­the­better characteristics. In this method the decision makers could make a grouping of attributes by their priorities. This research is based on the assumption of an equality between the attributes of MADM with the characteristics of Taguchi method. As a result, this interactive method could transform the characteristic value of Taguchi method into the size of SN ratios which are relatively easy to understand by decision makers.

  • The goal of this paper is to offer a quantitative decision model using Quality Function Deployment(QFD). We consider the factors outsourcing that affect the benefits of the organization and the fifth alternatives that were selected to be considered for outsourcing as customer requirements and technical attributes in QFD. For selecting the outsourcing system, we compute the priority considering interdependencies among alternatives. Thus this paper propose a decision model, which uses the quality function deployment to help practitioners set priority and users in structuring the outsourcing problems.
