It provides a simple, scientific and technological solution for many fields. The high development of information bring digitized concept to every sections. So, Software development, operation, testing and other steps will be affect by those fields. Therefore, the development of the software industry needs to improve the management efficiency, and improve the efficiency of product development in the whole process.展开更多

Their per-unit cost does not decrease but increase with the growth of such projects product size. Thus this is diseconomies of scale that occur in them. The significance of this phenomenon results from the fact that it is commonly considered to be one of the fundamental objective causes of their low effectiveness. This is of particular significance with regard to Business Software Systems （BSS） D＆EP characterized by exceptionally low effectiveness comparing to other software D＆EP. Thus the paper aims at answering the following two questions： （1） Do economies of scale really not occur in BSS D＆EP？ （2） If economies of scale may occur in BSS D＆EP, what factors are then promoting them？ These issues classify into economics problems of software engineering research and practice.展开更多

This new system puts the previously constructed the Amalab-project planning navigation system （A-PPNS） to work throughout the entire organization. The A-IOMS has several key elements. Specifically, the authors have constructed： （1） a Hi-reliability estimation system diagnostic tool that pinpoints problems with software development estimates and offers a prescription for resolving them; （2） a QA table map that allows for an immediate, thorough, and consistent quality assurance process; （3） a system for sharing software development schedules throughout the organization; and （4） a technological asset completion reporting system for passing down and cultivating software development technologies and strategically expanding them. The authors verified the effectiveness of the A-IOMS at company A, a systems integration company, and the given outcomes were obtained.展开更多

The optimized operating parameters were obtained through the energy utilization analysis,process simulation,heat exchanger calculations and comparisons of utility consumption. The operation of commercialized unit has revealed that the design parameters of each rectification column were consistent with the operation results,and the utility consumption was about 47% lower than the traditional heat integrated process.展开更多
