In apartment building with column structure, reinforcing bar of the column is constructed mainly using gas pressure welding job. Therefore, gas pressure welding job in very critical process is construction apartment building with column structure. The purpose of this study is to analyze productivity of gas pressure welding work in column structure apartment using Web-CYCLONE. In this study, a CYCLONE model was developed for the productivity analysis of gas pressure welding work. Through this model, the optimal combination of the resources was obtained. This study will be utilized in the future as a useful tool of productivity analysis and the determination of an optimal combination of resources for gas pressure welding in apartment with column structure.

Construction processes are highly repetitive. A resource entity continuously cycles through work tasks that processes or uses resources. Web-CYCLONE (Halpin 1992) has been accepted as a useful tool for modeling and analyzing a specific operation. However the system has a lack of practicality as follows: (1) it does not efficiently record and keep track of operation models in a database; (2) it does not provide the functions which facilitate to retrieve corresponding model and to update local variables of the model using observed data; (3) it does not automate the complex process that executes simulation experiment, analyzes simulation outputs and generates a report on behalf of the practitioners. Therefore, practitioners have a difficulty in reusing, modifying and analyzing the existing operation models. This study introduces a Client/Server based CYCLONE that improves above-mentioned limitations in the existing Web-CYCLONE. The system was illustrated by revising CSPU in practice.

1970년대부터 고도의 산업발전을 이루기 시작한 국내 건설현장에서 저렴한 공사비용 및 간편한 시공성 등을 장점으로 샌드위치패널을 활용한 건축물이 급격하게 증가하는 실정이다. 하지만 샌드위치 패널의 시공을 담당하는 기업들은 대형 건설기업보다 중소건설업체에서 시공하기 때문에 생산성 향상을 위한 연구가 부족한 상황이다. 본 연구는 샌드위치패널공사현장을 실사하여 작업조별 작업싸이클을 분석하고 Web-Cyclone을 이용한 모델링을 구축하여, 각 작업조별 생산성 및 공사금액을 분석하였다. 이를 활용하여 샌드위치패널공사의 작업조 생산성 정보를 상대적으로 연구가 부족한 국내 중 소규모 전문건설업체들이 자신들의 현장 특성에 적합한 샌드위치패널공사의 생산성 및 공사금액을 예측 및 적용할 수 있을 것이다. 또한 본 연구에서 작성한 모델링을 기반으로 유사한 공정에 대하여 시뮬레이션을 모델링화하는데 적용될 수 있을 것으로 예상된다.

This study was conducted to present useful information on the utilization and productivity analysis of laminated modular multi-family housing. To this end, the process of site installation was investigated and analyzed through a prior study, and the monitoring survey was conducted through the site installation case of an stacked multi-family housing. Based on the above, the results of productivity analysis using the web-cyclone technique were also presented. However, the site installation process has limitations on generalisation because the process is not the same for each construction company, and also limits that require verification through application in the actual site of the web-cyclone model presented in this study.

The aim of this study is to evaluate the productivity of multilayered modular housing units during the prefabrication phase. Additionally, it shows the results of productivity analysis conducted using the Web Cyclone technique. Initially, an review of literature and prior studies helped outline the comprehensive manufacturing process of laminated modular apartments, examining the range of minimum, average, and maximum work durations along with workforce size. Subsequently, the productivity of the multilayered apartments' prefabrication was assessed using the Web Cyclone technique, focusing on the workflow, duration, and personnel involved. This analysis also included a comparison of productivity against the initial plan based on the outcomes of a sensitivity analysis.

Demands for digital transformation of the construction industry are increasing to improve the accuracy of the construction operation planning and the performance of the construction operation. Even though large number of studies are being conducted to this date, most of the studies are not likely to be available on the real sites. Therefore, this study provides construction managers with a methodology of drawing construction performance indicators based on productivity analysis using Artificial Neural Network (ANN) models and Web-CYCLONE. This methodology is expected to have high utilization and precision of construction operation planning and management.

This study introduces a method for computation of process and operation gap in the specific construction operation(i.e., RC frame construction applying a block-grouping scheme) using CYCLONE-based simulation modeling and analysis technique. Since uncertainty of construction environment exists, a thoughtful production planning is required to effectively deal with a risk resulting in schedule delay in advance. This study presents the concepts of a time delay occurred in a process level and operation level in a operation model, and a method of measuring gap-times in each level while the simulation progresses. It helps a site manager to decide how many segmentation in a construction block is suitable for eliminating unproductive time-delays under the constrained resources (e.g., laborer, equipment). A case study presents a network model representing a three segmented RC frame work, and result obtained from the simulation experiment.
