Information processing culture is presented as an integrative concept for representing the cultural aspects of organizational information processing, and its effects on organizational information processing effectiveness are investigated. Based upon a review of literature on organizational culture, the dimensions of information processing culture are drawn and validated empirically. It is found that information processing culture consists of two dimensions, information value perception and information processing rituals, the latter being further consisting of the volume of formal information processing, the structural support for information processing, and the degree of formalization for information recording and transmission. It is also found that information value perception has a strong effect on organizational information processing effectiveness. The implications of the findings are discussed.

Recently, GPU cloud computing technology applying GPU(Graphics Processing Unit) devices to virtual machines is widely used in the cloud environment. In a cloud environment, GPU devices assigned to virtual machines can perform operations faster than CPUs through massively parallel processing, which can provide many benefits when operating high-performance computing services in a variety of fields in a cloud environment. In a cloud environment, a GPU device can help improve the performance of a virtual machine, but the virtual machine scheduler, which is based on the CPU usage time of a virtual machine, does not take into account GPU device usage time, affecting the performance of other virtual machines. In this paper, we test and analyze the performance degradation of other virtual machines due to the virtual machine that performs GPGPU(General-Purpose computing on Graphics Processing Units) task in the direct path based GPU virtualization environment, which is often used when assigning GPUs to virtual machines in cloud environments. Then to solve this problem, we propose a GPGPU task management method for a virtual machine.

In this paper, in order to improve production processing for small and medium-sized precision processing companies, we apply a manufacturing execution system to existing process methods and integrate precision processing data to strengthen process management within the company, increase facility operation efficiency, and realize a reduction in defect rates. The differences in productivity improvement and cost reduction rates were compared and analyzed. As a result, production productivity improved by 7.0% and product defect rate improved by 0.1% point due to the introduction of the manufacturing execution system. It was confirmed that manufacturing cost reduction improved by 10.0% and delivery compliance rate improved by 1.1%. If additional smart factory technology is applied based on the manufacturing execution system proposed in this study in the future, sales and profits in the processing industry are expected to increase due to an increase in the PQCD index.

GMS(Globalization Management System)는 기업의 문서, 데이터베이스, 기업용 프로그램, 웹 사이트, 매뉴얼 등에 있는 다국어 정보를 관리하는 기업용 프로그램이다. GMS는 기업 정보의 다국어, 다지역, 다문화별 관리를 가능하게 한다. 따라서 기본적으로 전세계에서 동시에 발생하는 수백개의 지역화(localization. LION) 프로젝트를 관리할 수 있어야 하며, 더 나아가 세계화(Globalization, G11N) 관리 기능을 제공해야 한다. 세계화 프로세스라는 면에서 볼 때. 소프트웨어 프로그램의 세계화 프로세스와 웹사이트의 세계화 프로세스는 성격이 달라서 접근 방법이나 요구되는 기술이 다르기에 본 논문에서는 웹사이트 세계화(이하, WG)중심의 GMS 이해를 목표로 내용을 전개하고자 한다.(중략)

This paper considers a parallel-machine scheduling problem with dedicated and common processing machines. Non-identical setup and processing times are assumed for each machine. A genetic algorithm is proposed to minimize the makespan objective measure. In this paper, a lowerbound and some heuristic algorithms are derived and tested through computational experiments.

We address the problem of determining the optimal processing times and pallet/fixture allocation in Flexible Manufacturing systems in order to minimize tool cost while meeting throughput targets of multiple part types. The problem is formulated as a nonlinear program superimposed on a closed queueing network of the FMSs under consideration. A numerical example reveals the potential of our approach for significant cost saving. We argue that our model can be Integrated Into the process planning system of an FMS to generate efficient process plans quickly.

A single machine stochastic scheduling problem is considered. Associated with each job is its random processing time and random deferral cost. The criterion is to order the jobs so as to minimize the sum of the deferral costs. The expected sum of the deferral costs is theroretically derived under the stochastic situation for each of several scheduling decision rules which are well known for the deterministic environment. It is also shown that certain stochastic problems can be reduced to equivalent deterministic problems. Two examples are illustrated to show the expected total deferral costs.

The objective of this study is to determine a near-optimal time schedule for processing necessary jobs in order to minimize total elapsed time. The fundamental assumptions are that jobs to be processed are classified into several groups and jobs within the same group are processed in succession in the flow-type GT line. A heuristic method by V. A. Petrov is applied to determine the job sequencing. In consideration of production quantity, group sequences and job sequences for each group are determined and the start time of processing for each job is calculated by computer.

This thesis defines an end-to-end billing process model. The processes in the model can be mapped to the TMN(Telecommunications Management Network) model which is based on an international telecommunications management standard. We have identified two interfaces in this billing process model. Part 1 of this thesis provides a protocol-independent design of the UAI(Usage Accounting interface) between the service provider and the network provider. Part 2 of this thesis provides information modeling of the UMI(Usage Metering Interface) between the network provider and the equipment provider. This interface is applied to the B-ICI(Broadband ISDN Inter-Carrier Interface) environment.
