  • 장치공간 소요량은 컨테이너터미널의 장치능력을 결정짓는 매우 중요한 의사결정 변수이다. 일반적으로 장치공간 소요량은 모선의 배선간격, 장치허용기간, 본선작업시간 등 여러 요인들에 좌우된다. 그러나 지금까지는 이들 요인이 확정적이라는 가정 하에 다양한 방법들을 장치공간 소요량 산정에 적용해왔다. 본 연구는 본선작업 물량이 확률적인 것으로 가정하고 요구된 서비스수준을 만족시키는 장치공간 소요량의 산정 방법을 제시했다. 시뮬레이션을 이용한 수치실험은 제시된 방법이 다른 방법들에 비해 확률적 상황에서 더욱 정확한 장치공간 소요량을 산정할 수 있음을 보여주었다.

  • As a rapid supply of a culture facility the change of living style bring on needs about storage space in the residence space. This study choose Hong Je Dong-Byuk San 4 type apartment house which was built in 1990 as research target and we selected 4type of a total 12house and we choose LDK as a research target that is high in a requirement and utilization other space is excluded in this study. We can expect that the apartment house will be differed with area of living space of apartment house in the requirement of storage space. Small apartment house is requried various storage planning because of confined living space But big apartment houses required storage planning of simple type because it have already storage space. So we have to do efficiency storage planning because of limited space in the apartment house. Base on this results we will show storage space according to the type of pyeong. So this study show proper storage type according to the scale of apartment house,.

  • This paper considers a trade-off effect between in-house storage space and leased storage space in generic warehouses operated under a randomized storage assignment policy. The amount of in-house storage space is determined based on the law of large numbers satisfying a given service level of protection against space shortages. Excess space requirement is assumed to be met via leased storage space. A new analytic model is formulated for determining the excess space such that the total cost of storage space is minimized. Finally, computational results are provided for the systems where the standard economic-order-quantity inventory model is used for all items.

  • High performance and reliability of the storage system to handle a very large amount of data has been become very important. Many techniques have been applied on the various application systems to establish very large capacity storage that satisfy the requirement of high I/O speed and physical or logical failure protection. We applied RAID and LVM to construct a storage system for the global data center which needs a very reliable large capacity storage system. The storage system is successfully established and equipped on the latest Linux application server.

  • I recognized necessity of the space planning to three-generation dwelling because of preservation of wholesome society sense of values of the younger generation indicated often to the point at issue by the change to nuclear family of present and by way to hand down thought of respect for the aged which is our traditional public morals. I wish to present basic data for storage space planning that resident's request and consciousness are reflected in such background. I investigated records in general concept, which is utilization pattern of storage space to achieve the function of these culture intermediation. The object of research is three-generation dwelling, such as 3L-K and 3L-DK as national residences that appear most generally in chongju city. The method of research was question investigation method to write utilization actual conditions and requirement of storage space directly. So I proposed suitable planning to resident's life style analyzing frequency, percentage and average distribution. When supply apartment house hereafter, it should be reflected wide selection by resident's characteristic and needed systematic storage space planning in consideration of user mainly. Also continuous and diversified researches that can improve quality of residence are required.

  • This study aims to analyze the cases of storage space outside housing unit and propose the activation plan. The issue of storage in residential complex has continued to be reported. This is more salient due to the recent preference trend for small houses, the constant increase of living goods and the limitation of the available space inside housing unit. Although more apartment houses are trying to have individual storage in the exterior space to address these issues, there is still a paucity of the related studies and more studies are required. In this study, we conducted on-site investigation and user interview of each case to propose active usage of the storage space outside housing unit. Result of this study shows that the most crucial factor to improve is 'accessibility' in order to activate the storage space. Storage room should be located close to each household or the individual parking space. The second factor is the size and the structure of the storage room. The sufficient space for keeping and taking large objects out are required. The front of the storage room should have a clogged structure to insure privacy. The third is the provision of suitable support programs such as the system that occupants can check remotely what items are in their storage rooms, garage sale, laundry service, auto cleaning system and rental program. Those programs are required for efficient management and activation of space. Another requirement is to improve environmental factors which include maintenance of optimal temperature and humidity, automatic ventilation system, control of individual lights, and security enhancement. Based on the results of the survey, we provide basic data which can be used for practical space planning to activate exterior storage space of the housing unit. Further surveys are required to develop this study by obtaining more data for generalization.

  • In this paper, we provide some fundamental properties and basic theoretical results of K-class-based dedicated storage policy in a unit load system assuming the constant-space assumption that the number of storage locations for a class is not the maximum aggregate inventory position for a class but the sum of space requirement for products assigned to the class. The main theorem is that there exists a (K+1) -class-based storage layout whose expexted single command (SC) travel time is not greater than that of a K-class-based storage layout, i.e, $E(SC^*_{K+1}){\leq}E(SC^*_K)\;for\;K=1,{\cdots}$, (n-1).

  • This paper concerns the design and implementation of a Bandwidth Variable Digital Chirp Generator (DCG) for the radar altimeter. A double SRAM parallel structure is used to breakthrough the upper DCG bandwidth limited by the highest clock frequency of the digital chips. An experimental system working in the waveform storage method has been implemented. We show that the bandwidth changed according to the radar altimeter's requirement and the design released the stringent speed requirement of the chips fur making a variable wide bandwidth DCG.

  • Block stacking, which involves the storage of unit loads in stacks within storage rows, is typically used in traditional warehouses to achieve a high space utilization at a low investment cost. In this paper, assuming that the demand size from a customer is an i.i.d. random variable, we develop a probabilistic block stacking storage model and its algorithm for a singles product, which minimizes the time-overage floor space requirement under an (s, S) inventory policy and the violation of the FIFO lot rotation rule only in a single partially-occupied row.

  • In this paper, we address a layout design problem for determining an optimal 4-class-based dedicated linear storage layout in a class of unit load storage systems. Assuming that space requirement for a class is the sum of the maximum inventory levels of products assigned to the class, and that one-way travel time is a linear function of storage index, we formulate a 4-class-based dedicated linear storage problem PTL[4] and provide an exact splitting algorithm with $O(n{\lceil}logn{\rceil})$. Our algorithms could be applied to more than a 4-class-based dedicated storage layout problem with slight modification in order to reduce computational execution time.
