This study deals with problems of estimating the availability of the multi-module software systems. The result presented in this paper is an extension of our previous paper (2) entitled "A modified Markov model for the estimation of computer software performance". The extension is made by assuming that (1) the software system consists of R statistically independent software modules; (2) no failure occurrence while the process is in transition between software modules.

Effective management of a project is a crucial issue to software companies. There are various international standards, such as CMM, ISO9000, and SPICE, applied to project management. But, small scale companies have some difficulties in accepting those standards because of its complexity and enormous manpower requirements. This study proposes a project management approach streamlining the CMM by which a small scale software company can perform the tasks with ease. A prototype system has also been developed to show the capability of the proposed model.

This paper developed an operating software for the manufacturing cell of a model plant. The model plant, which was manufactured by Fishertechnik, consists of an assembly cell, a machining cell, and supplementary material handling equipments. Each I/O module of the model plant communicates with the INTERBUS controller devices via High-level Language Interface(HLI). The machining center has two machining cells, which consists of 4 machines respectively, two 3-axis portal transporters, and a rail guided vehicle(RGV). The Petri-Net was used to investigate the dynamics of each machining cell, e.g., the relation of material handling equipments and machines. The operating software was analyzed and designed by Object Oriented Technique. The software was implemented using Delphi 3.0 under Windows 95/NT operating system.

In this paper a software program is given for food product life (shelf life) estimation. There are many modules of related operations, considering the characteristic of food industry so that users can easily use and understand the software, and we make the related data referenced In data base. In food industry acceleration tests depend on food deterioration differential equations. Based on such equations, etc, this paper suggests a shelf life estimation software program.

Recently, IoT, artificial intelligence, cloud, big data, and mobile fields have converged, leading to a new industrial era called the 4th industrial revolution. This 4th industrial revolution has been expanded to all industry area and Software has been taken as important role in this revolution. Thus Software Safety is the huge factor because Software is highly relevant to human safety in accordance with Software expansion. However this Software Safety has been focused on not organization improvement activities but current design/development, In this paper, to solve this issue, Software Safety Maturity level and relevant Process Area is defined. This study is expected to contribute to systematic software safety activities.

Industrial ventilation is a crucial engineering measure to protect workers from hazardous airborne contaminants. Designing a ventilation system is not an easy task. To solve this problem, many U. S. computer programs and softwares have been developed. In Korea, asoftware, called as VPMC, was developed by Korea Industrial Safety Corporation. But VPMC could not stand alone since it can be used to design not a hood, but a ventilation system. In this research, therefore, a preprocessing software was developed. It can be used to design general ventilation system, canopy hood, open surface tank hood. The program was written in Microsoft Visual Basic. In near future, this software will be incorporated into a total package software which can be used to design a whole ventilation system.

Quality Assurance Principles must be effectively implemented in developments and in use of safety critical software in nuclear industry. Brief definitions related to computer software and quality assurance were defined and several methods for evaluating software quality were proposed herewith. Independent verification and validation was suggested to assure the quality of safety critical software.

This article investigates the software acquisition problems as two dimensional : custom/pacakage and insource /outsource. The analysis adopts the cost-benefit frame work in explaining software acquisition problems and takes two leveled approach. The first level examines the cost-benefit relationship of the determinants affecting both dimensions, and these determinants are derived from theories of transaction cost, incomplete contracting, and agency. The second level focuses on the impact of general cost-benefit frivers of the software acquisition decisions. The results facilitate a broader and more detailed understanding on the software acquisition problems.

Research on information systems and software engineering has often neglected behavioral effects, which may play a role in decision making on software development. The current study addresses this issue by empirically investigating the behavioral roots of over-requirement in the context of a software development project via an experiment. The negative phenomenon of over-requirement refers to specifying a software system beyond the actual needs of the customer or the market, which overload the system with unneeded features. The research question addressed here is whether over-requirement is due in part to the emotional involvement of developers with the software features they developed because of behavioral effects. Previous studies have demonstrated that under the endowment, I-designed-it-myself, and IKEA effects, people become emotionally involved and overvalue physical items that they respectively possess, self-design, or self-create. The findings of our experiment show that participants over-valued features they were assigned to be responsible for, to specify, or to construct, thereby confirming that the three behavioral effects play a role in software development decisions and affect over-requirement. Thus, the study contributes to software development research and practice from the behavioral economics perspective, highlighting the roots of over-requirement.
