State transportation agencies depend on advancements in information technology to help manage the billions of dollars spent on thousands of construction projects every year. As transportation planning and programming become increasingly complex, communication among different divisions of the agencies is becoming even more important. This paper describes an effort to apply business process modeling to aid the integration of planning and programming of construction projects for a state transportation agency, metropolitan planning organizations, and related agencies. Business process models are developed according to the IDEF modeling standard that is used in Computer Associates AllFusion Process Modeler. IDEF modeling provides structured documentation about the processes of the agency while improving the transparency and validity of agency activities. Furthermore, IDEF modeling helps to determine bottlenecks in the current processes and supports the prioritization of investments in reengineering and associated information technologies. IDEF modeling enables employees at different levels of the agency to understand the business processes of their professional colleagues. Several lessons of the effort are as follows, (i) IDEF modeling can be translated efficiently to simulation models that provided increased detail of critical activities. (ii) The use of information technology is recommended to provide for real-time monitoring of selected planning and programming activities, (iii) Sources of risk to various agency activities need to be modeled explicitly by theoretical extension of the current IDEF methodology. Numerous examples and case studies are provided in the paper.
国家交通机构依靠信息技术的进步来帮助管理每年花费在数千个建设项目上的数十亿美元。随着交通规划和规划变得越来越复杂，各机构不同部门之间的沟通变得更加重要。本文描述了一项应用业务流程建模的工作，以帮助州交通机构、都市规划组织和相关机构整合建设项目的规划和规划。业务流程模型是根据Computer Associates AllFusion process Modeler中使用的IDEF建模标准开发的。IDEF建模提供了关于机构流程的结构化文档，同时提高了机构活动的透明度和有效性。此外，IDEF建模有助于确定当前流程中的瓶颈，并支持对再工程和相关信息技术进行投资的优先级排序。IDEF建模使机构不同级别的员工能够理解其专业同事的业务流程。这项工作的几个教训如下:(i) IDEF建模可以有效地转化为模拟模型，提供更多关键活动的细节。建议利用信息技术对选定的规划和方案拟订活动进行实时监测;各机构活动的风险来源需要从理论上扩展目前的非洲发展基金方法，明确地加以模拟。文中提供了大量的实例和案例研究。

Army research initiatives include research and development of unattended ground sensors (UGS). UGS will improve the ability of tactical units to collect information and are expected to play an increasingly important role. Sensors are of several types, including acoustic, seismic, magnetic, electric field, and imaging. It is expected that deployed sensors will be self-organizing to form a sensor field. Because of power and communication limitations, it is anticipated that the sensor field will be required to process data locally, and report only the results of this analysis. Given detection, the report will include the classification or identification of an object transiting the field, as well as the field's self-assessed level of confidence in the estimate. This study examined the level of confidence required before a decision maker would reallocate resources based on the report. Combat arms officers were provided a tactical situation and the sensor field level of confidence required before commitment of forces was elicited. A computer model was then used to investigate what sensor mixtures and densities were required to meet this threshold. The impact of correct and incorrect decisions for a tactical situation was examined using high-resolution combat model. Additionally, the responsible unit level and doctrinal employment were examined.

The purpose of our research is to define a battle unit and to create a systems evaluation process to evaluate the military impact and value of using Scramjet technology in weapons systems as envisioned in military scenarios defined for the battle unit to engage threats. The initial stakeholder is the United States Army. The stakeholder needs are defined as follows: evaluate the possible contribution of Scramjet technology to army transformation and development of future combat systems. Evaluations will then be measured against the objectives of flexibility, adaptability, lethality, response time, and the resultant impact on mission success. We model the system of attacker and defender by a network of queues with special queuing and service rules. Our battle unit will consist of a sensor system, a command and control system, and a defender system with n units. The units will have attributes assumed to be given. We approximate the system evaluation by a network of queues with balking and general service and general arrival distributions.

The paper summarizes the methods and results of a research and development effort performed by undergraduate students of the Department of Industrial and Systems Engineering (ISE) at Virginia Tech. The United Parcel Service (UPS) operates approximately an 1100 package car delivery fleet spread among 24 package (distribution) centers within their Virginia shipping district. The objective of this effort is to more optimally spread the UPS delivery fleet across the district to minimize fueling costs. UPS incurs a daily operating cost resulting primarily from the fueling of package cars. The reduction in fuel costs of the UPS fleet is ensured by matching the fuel efficiencies of different package cars to their delivery route lengths. A software tool was developed consisting of a linear program and a user interface that more optimally allocated the UPS fleet, resulting in met delivery requirements and a potential $180,000 annual savings in fleet fueling costs.
