  • The purpose of this study is to develop spatial configuration and area calculation method of warehoue. This paper deals with warehouses with palletized cargo since recently pallets are widely used in many warehouses to enhance efficiency. We identify spatial configuration and characteristics of each area. To represent realistic situations, we analyze characteristics of logistics equipment as well as interview results with expert warehouse architects. Through these analysis we suggest guidelines on area calculation of warehouse.

  • A fire risk assessment in rack-type warehouse is typically determined based on the following factors: 1. flammability and fire loads for storage of goods, packing materials, and pallet, 2. a ceiling height of warehouse indoor spaces, and 3. height, arrangement, and spacing for storage racks. For appropriately extinguishing and protecting the fire in warehouses, therefore, it is necessary to classify combustibles considering the previously mentioned factors and to develop design Standards for sprinkler system. As the first step to apply automatic sprinkler system to domestic warehouses, this study investigated characteristics for commodity distribution and warehouse configuration using 28 warehouses in five distribution complexes located in Gyeonggi-do, South Korea. In addition, this study analyzed Standards for commodity distribution adopted in USA, Europe, and Japan. Using the field survey analysis, this study was aimed to provide baseline data to prepare for Commodity Classification Standard for warehouses in South Korea.

  • To build a most efficient and competitive warehouse, need to reflect tenants various opinions in advance such as location, rentable size, leasing terms, rental, configuration of the building, building structure, traffic flow and amenities. Thus a survey for major tenants which are logistics, retailers and manufactures should be done to figure out potential demand and marketing strategy to lead to be a competitive warehouse. However above survey is time consuming work and requires high cost involvement thus to avoid such an inefficient process and to facilitate investors prompt and right decision making, there should be a tool which helps to make a decision process easier with simple key factors. In other word, we have used above mentioned 'Demand Approach' so far but here I am introducing 'Factors Comparison' which reflects location factors and facility factors. I derived Kwang-myung logistics park's proper rental rate through 'Demand Approach' which analyzed Seoul Metropolitan area's rental warehouse status and rents, and also defined a size of potential demand area and rental. And this report compared the result with an outcome of 'Factors Comparison' then compared each methods and drew a conclusion of 'Factors Comparion's better convenience and efficiency.

  • The warehousing of inventories is an enormous expense to industries worldwide, and yet there are few available that can be used to design rack storage systems while considering overall system costs. The primary objective of this paper is the development of an overall ware hous storage system costs model to aid a warehous planner in the design of automated warehouse systems. A simulation model and statistical estimation procedures are used to determine the maximum inventory levels accumulated in the receiving, storage, and shipping areas. The overall cost model is developed to determine the required total land, the initial investment fund, the number of pieces of handling equipment, and the storage rack configuration for the main storage area. A numerical example is then presented to demonstrate the application of the overall system cost model developed in this paper.

  • A data warehouse stores information that is collected from multiple, heterogeneous information sources for the purpose of complex querying and analysis. Information in the warehouse is typically stored In the form of materialized views, which represent pre-computed portions of frequently asked queries. One of the most important tasks of designing a warehouse is the selection of materialized views to be maintained in the warehouse. The goal is to select a set of views so that the total query response time over all queries can be minimized while a limited amount of time for maintaining the views is given(maintenance-cost view selection problem). In this paper, we propose an efficient solution to the maintenance-cost view selection problem using a genetic algorithm for computing a near-optimal set of views. Specifically, we explore the maintenance-cost view selection problem in the context of OR view graphs. We show that our approach represents a dramatic improvement in terms of time complexity over existing search-based approaches that use heuristics. Our analysis shows that the algorithm consistently yields a solution that only has an additional 10% of query cost of over the optimal query cost while at the same time exhibits an impressive performance of only a linear increase in execution time. We have implemented a prototype version of our algorithm that is used to evaluate our approach.

  • This paper proposes an integrated management system for products of game software development. Those products generated over software life-cycle are generally huge in numbers, various in kinds and interconnected in relationships among them. Especially they are highly complex and tightly coupled each other because they are used to build another world which is composed of multi-modal data such as graphics, sound, logics and so on. Therefore it is critical to manage development products in an integrated manner to guarantee the quality of software. The proposed system is designed to provide project/requirement/configuration/traceability management capabilities and interfacing to CASE standards. To achieve the objective, it is based on data warehouse technologies which provide central repositories of heterogeneous data, multi-aspect reporting&analysis capabilities, traceability, verification, etc.

  • Nakseonjae in Changdeokgung Palace was established at The King Hunjong's 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king's concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king's shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women's quarters) and Sarangchae (men's quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king's dwelling place, and spaces for house's collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants' quarters for assisting the Royal family. In detailed structural styles, column's size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king's shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang's upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.
