Studies in software reengineering: Capturing navy legacy software

This report is a summary of the continuing efforts of several teams at the Naval Surface Warfare Center, Dahlgren Divsion (NSWCDD) to evaluate technologies and to define and refine a process to reengineer Navy legacy CMS-2 code into Ada. This effort involves tool and technology evaluation, methodology definition, and cost model definition.For systems developed in CMS-2, a Navy specific high order language, consideration must be given as to the most cost effective method of converting to the current high order language of choice, i.e., Ada, without losing the legacy lessons learned. NSWCDD engineers evaluated three translation tools, evaluated reverse engineering technologies, and defined both a process and a methodology to incrementally transition Navy CMS-2 code into Ada. The source code used for the evaluation is from the AEGIS Weapon System and the distributed, open environment is the High Performance Distributed Computing Program co-sponsored by the Advanced Research Projects Agency and the AEGIS Program Manager.Many of the issues identified throughout these studies are unresolved, but software engineers are continuing to evaluated the impacts of transitioning to commercial environments and Ada. Some of the issues that are being studied follow: testing of distributed systems; system level integration; lack of time-stamped instrumentation: and reliability in commercial-off-the shelf environments. The Navy is in the early stages of identifying impacts of transitioning to Ada, commercial environments, and distributed architectures. NSWCDD is gathering data to confirm that capturing legacy systems, whether it is code or design ideas, is essential to minimizing the cost and the risk of these transitions. It is also evident that technology is neither mature nor ideal yet to satisfy the identified needs for capturing the legacy of a proven system. Translation, while useful to a point, is not suitable alone as a solution to the transition equation.     

Enterprise networks: The re-engineering of complex software systems

Today technology design can no longer be understood as a design process on a green site. Design and implementation of new technology are always dependent on existing technology and the way it is used by people. In this respect Software-Engineering has also changed to the characteristics of normal technology design taking into account existing computer systems. Experiences show that the conditions and needs of such Software-Reengineering projects are highly complex and differ in their special characteristics ranging from aspects of quality of existing system documentation to organizational structures of the computer departments concerned. The Task-Artifact Cycle presented here gives a suitable reengineering approach emphasizing both analysis and design in Software-Reengineering.

企业管理的业务流程重组

随着计算机技术、网络信息化的发展与成熟，企业正在向信息化管理转变。企业在引进、实施管理信息化的过程中，面临了管理模式差异的挑战。本文通过实例来说明企业在构建管理信息化平台的同时，会出现管理模式及业务流程的差异，可通过业务流程重组技术来协调这些差异，井提出了该差异解决的方案。     

现代大学教育管理流程再造初探

企业业务流程再造被誉为工商管理的一次革命。基于管理的共性和环境的变化，我国的大学教育管理也到了流程再造的时候了。我国当前的大学教育管理流程具有许多不足，如何展开流程再造是一个崭新的课题。本就现代大学教育管理的流程再造的基本原则和策略进行了步探索，以达抛砖引玉之目的。     

企业过程再造：一个案例研究

企业过程再造是为了实现企业经营业绩的突破而对企业经营过程进行的根本性改造。实施过程再造常见的方法就是对企业现有经营过程进行分析和重新设计。但是这个出发点实际上极大地限制了对问题的解决,与过程再造的“根本性”的特点相矛盾。通过分析一个科技书店再造的案例,指出了实施过程再造时,既要从企业现有经营过程出发,又要超越这个范畴,从更广阔的视野寻找解决问题的方案。在案例分析的基础上,对企业过程再造理论进行了一     

基于目标分析的BPR模型在证券经纪业风险管理模式变革中的应用

基于目标分析的流程再造(BPR)技术为战略层面分析多行为人的目标意图提供了企业建模依据,这种新方法为我国证券经纪业务风险管理模式变革提供了可行思路.采用战略依赖模型和战略推理模型等面向目标的BPR技术分析了我国经纪业务资金管理模式,研究发现交易过程中多营业部的参与是总部难以有效控制各种风险的关键要因,提出分散模式的过渡变革策略"独立存管模式"以及彻底的BPR策略"第三方存管模式",为改善我国证券经纪业风险管理提供了有益建议.     

中国信息化趋势报告(三十四)信息资源整合技术报告(1)

信息资源整合（IRI）技术，是我们自1986年在国内率先引进国际先进的信息工程和数据管理等理论方法，经过十多年的研究实践和．营、结创新，为政府部门和企事业单位的信息资源开发利用提供的一整套理论方法、标准规范和支持工具等关键性的系列技术。通过长期的研究开发和多项试点示范工程的成功，获得了一批技术成果，证明了IRI技术对消除“信息孤岛”，避免信息化“黑洞”具有突出的效用。本报告阐明了信息资源整合的前提是进行统一的信息资源规划，信息资源整合的基础是建立信息资源管理基础标准，信息资源整合的实质是数据环境的重建。推广IRI技术对于加强信息资源开发利用工作，推进国家信息化建设，具有重大的现实意义和深远的历史意义。     

Setting checkpoints in legacy code to improve fault-tolerance

In this paper we describe the results of a study of the insertion of checkpoints within a legacy software system in the aerospace domain. The purpose of the checkpoints was to improve program fault-tolerance during program execution by rolling back system control to a saved state from which program execution can continue. The study used novice programmers for the determination of where the checkpoints were to be added. The focus was on the programmer’s understanding of the code, since this affected how the checkpoints were placed. The results should provide guidance to those interested in improving the fault-tolerance of legacy software systems, especially those written in older, nearly obsolescent programming languages.
