  • Task based modeling is essential in a construction operation simulation modeling. It allows dealing with local variables or delay factors that affect productivity and improves the reusability of existing operation models. An operation model can secure reality only if it reflects the real construction processes by effectively dealing with zoning issue. However, system users have some difficulties in modeling a construction operation that is consisted of several processes having different production units. Zoning is a major modeling issue when the task based modeling method is implemented using the existing discrete event simulation systems. This paper highlights the difficulty and presents a new method that complements the zoning issues attributed to different production units. The method is described in detail by presenting the flow of entities. It is confirmed that the zoning method effectively deals with the unbalance of production units between processes and facilitates to model an operation model having processes with different production units. The "Zoning module" contributes to increasing accuracy of simulation result.

  • An inappropriate space zoning plan causes the unnecessary transportation of construction material and equipment among work areas and increases the disorder of work space. Space zoning is an essential operation management technique which contributes to reduce the process and/or operation idle-time. This paper introduces a method that computes the idle-times between construction operations (or processes) by using Web-CYCLONE. It allows computing with idle-times that affect the construction productivity. Using the idle time between operations and between processes, it computes the optimal number of zones and finds the optimal combination of zones that minimize the idle times. The method contributes to minimize the idle times relative to the operation schedule using complete enumeration. This paper presents the system prototype in detail. A case study is presented to demonstrate the system and verifies the validity of the model. It allows a project manager to establish space zoning plan that effectively segregates a project into optimal number of construction zones and to assign the constrained resources (e.g., laborer, equipment).

  • The aim of this study is to understand the plan characteristics used in unit floor planning mainly with examples of mixed-use residential tall buildings. The study will extract plan characteristics mainly using the graph expressive technique with essential information of the zoning function of residential space, rather than merely analyzing the various construction floor plans by type. The research method involves studying a group of 50-story buildings (over 200 meters) which were built between 2002 and 2008. Among 6 high-rise residential buildings case, we extract the most preferred type from 34 types, And then we simply classify rooms in 3 zoning, the master, living and children's zones. Finally we analyze the correlation among 3 simple zone and then extract some model type. The results of this study revealed three main findings. First, using the 3 functional zones, the shape of the main building and the unit floor plan can be analyzed simply even when they appear to be complicated. Second, we can extract common features when we analyze the unit floor plan from the viewpoint of the penetrability among 3 zoning. Third, we can extract 2 types when we analyze the unit floor plan from the viewpoint of 3 connected functional zoning concepts.

  • Particle contamination in a cleanroom is very complex with a complicated process and several pieces of spreading equipment. Detailed information on the locations of the contamination sources and the path of the contamination is needed for economical and efficient control of the contaminant particles in such a cleanroom. An allocation method was developed to quantitatively predict the contamination generated from the pollution sources. In this paper, we propose a zoning method to accelerate the computation time for estimating the contributions. Our results showed that we can quantitatively estimate the amount of contamination generated from pollution sources.

  • The current Development Impact Fee (DIF) Zoning Law allows Korean localities to designate the DIF Zone for the areas where there have been up-zoning in land-uses due to any minute additions and/or amendments in the existing clauses or provisions in the National Territory Planning Law as well as all other laws related to urban and regional planning. In reality, however, it is almost impossible to trace the sporadic and infinitesimal changes that might occur in every corner of the statutory clauses of a great number of planning related laws. This study, in an effort to overcome such practical difficulties, tries to chase the time-series zoning alterations in especially the consecutive land-use information layers of the Korea Land Information System (KLIS) as comparable analogues of the outcomes of the amendments in various planning laws. A study locality is chosen among the entire localities in the Capital Region based on the selection criteria dictated by the DIF Zoning Law such as the population- and building permit increase rate. It has been verified that the methodology suggested herein is practically applicable and successfully capable of extracting a number of DIF zones with considerable areal sizes, which could not have otherwise been possible. The consequences of this study, in this context, are expected to contribute to prevent the uncontrolled developments as the DIF Zoning Law itself was originally intended to achieve.

  • This study developed a GIS-based suitability assessment model of coastal zoning system that is needed in the substantial classification of coastal zoning system according to the establishment of law about coastal zoning system. First, this study investigated several kinds of regulations, GIS database and application system related coastal area. Also, grid data model was selected as the GIS analytical model for calculating items of suitability assessment of coastal zoning system. And Grid-based analytical method was suggested for calculating items composing of sea and spatial location characteristics including physical one. Critical values of items were presented using standards that were suggested in coastal regulations and land suitability assessment. Especially, this study presented a calculation method of continuous pattern as fuzzy set function for reflecting the characteristics of GIS data. And this study classified the suitability grade using Z-score and developed model designating coastal zone as conservation management priority, utilization management priority, and planning management priority. This study is judged that very efficient business performance is possible if we consider the spatial coverage of study area and GIS database when the suitability assessment model of coastal zoning system that is suggested in this study, is applied to business works.

  • The development impact fee (DIF) zoning is used to adequately provide the pre-planned urban infrastructures in those urban and regional sectors where significant urban sprawl has already taken place followed by the rapid population growth. The infrastructure installation fees are levied to those landowners whose properties belong to the DIF zone in which they enjoy the direct benefits that accrue from the installed infrastructures. While the law is deemed to be equitable in that the actual beneficiaries pay for their benefits, it is required to designate the zone boundaries accurately and consistently since they are the very dividers that differentiate the legitimate fee-payers and the free-riders. This study, especially, tries to test a seemingly advanced alternative, so-called the cost-weighted distance measure, as a potential candidate to replace the current air-distance measures to designate the zone boundaries. The statistics indicate that the coefficient of variation for major indices spread from 11.75 to 35.6 in the case of the latter method, it only ranges from 0.21 to 0.76 in the case of the former. The zonal outcomes also show much higher consistency in their shapes. It is hoped, in this context, that the study findings could possibly be adopted in the future research efforts expected soon to amend and improve the current DIF zoning law.
