Relaxation techniques for strictly convex network problems

Annals of Operations Research 1986年第1-4期5卷 517-538页

作者： Zenios, S.A. Mulvey, J.M. Engineering-Management Systems Program Civil Engineering Department Princeton University Princeton 08544 New Jersey United States

Gauss-Seidel type relaxation techniques are applied in the context of strictly convex pure networks with separable cost functions. The algorithm is an extension of the Bertsekas-Tseng approach for solving the linear network problem and its dual as a pair of monotropic programming problems. The method is extended to cover the class of generalized network problems. Alternative internal tactics for the dual problem are examined. Computational experiments -aimed at the improved efficiency of the algorithm - are presented. © 1986 J.C. Baltzer A.G., Scientific Publishing Company.

INFORMATION systems 1988年第2期13卷 193-210页

ADISSA is a methodology for Architectural Design of Information systems and Software, based on Structured Analysis. The architectural design includes: 1. (a) design of a tree-structured menu system, which interfaces between the users and the system—viewed as the “external architecture” of the system; and 2. (b) design of the transactions of the system, composed of various functions which are activated in response to user needs and various events in the universe of discourse—viewed as the “internal architecture” of the system. The menu tree and the transactions are tied up with the other major components of the system architecture: the inputs and outputs, and the database. ADISSA methodology is fully compatible and consistent with Structured Analysis, and therefore the stages of system analysis and design are integrated into one complete process.

System users have been a demonstrated source of innovations and breakthrough ideas. While there is a wealth of literature dedicated to understanding this source of innovation for its ability to generate new markets;understanding how users design and change systems remains understudied. As an initial step, this research seeks to understand problem solving mechanisms employed by users. To observe this phenomenon, this initial research considers an extreme case of user design, the development of a complex system. Three categories of change mechanisms were employed by users: user, method and material. As a departure from traditional design methods it was found that users view themselves as a dynamic component of the system and change themselves or their behaviors to enable system capabilities. In the case considered, users were able to rapidly develop a complex system to meet new requirements;interestingly this was accomplished with either modular or minimally invasive equipment changes. While traditional flexible design tenets were present in the materiel components of the system (e.g. robustness and modularity), the skill and capacity of the system users provided a separate source of system flexibility. © American Society for engineering management, 2015.

The history of much of Industrial engineering has its roots in the Industrial Revolution where technologies helped mechanize what had been manual labor. However a lot has changed in the 100 plus years since the Industrial Revolution started, and Industrial engineering rightly changed along with it. over time Industrial engineering has taken different focuses and embodied different instruction by different educational institutions. Is it only just 'gears and wrenches'? Or is there more to it? Are there specific identifiable focuses? If so, how could Industrial and systems engineering (ISE) articulate those focuses? If a university was to start a brand new Industrial and systems engineering program, what would it look like and why? These topics will be explored in this article focusing on the rollout of a brand new program in Industrial and systems engineering at Stevens Institute of Technology. © American Society for engineering Education, 2018.

Group purchasing (GP) is a procurement strategy that can be deployed by businesses for purchasing raw materials for less by benefiting from economies of scale in purchasing through consolidation of their demands. In this study the effect of establishing longer term buying relations (as opposed to single term or period) between the GP agent and the buyers on the procurement cost is investigated. In a long-term relationship setting, the buyers share demand information over a planning horizon with the GP agent, and are willing to take part in GP during this planning horizon. In lack of a long-term relationship, customers will make GP decisions in each period while in the longer term relationship case they will have a GP decision for multiple periods over the planning horizon in the presence of inventory holding. Mixed integer linear programming (MILP) models are developed to handle single period and long-term cases, and to compare the cost performance. An experimental analysis is presented to test the models under different inventory cost scenarios.

AN INTEGRATED METHODOLOGY FOR FUNCTIONAL-ANALYSIS, PROCESS DESIGN AND DATABASE DESIGN

引用

INFORMATION systems 1991年第1期16卷 49-64页

作者： SHOVAL, P Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University P.O. Box 653 Beer-Sheva 84105 Israel

A methodology that combines and integrates the major stages of information systems development is presented. The methodology is based on hierarchical data-flow diagrams which are used to perform a functional analysis of the system. This enables the conducting of process design on the one hand, and information structure analysis and database schema design on the other. Specifically, we describe a method that connects the transactions of the system (the product of the process design stage) with the record-types (the product of database design stage). This connection closes the gap between the "procedural" and "structural" aspects of the system, and enables a smooth transition to the stage of system construction. It also facilitates the designing of sub-systems and their sub-schemas. Software tools that support all stages of the methodology are reviewed, emphasizing the tool DS2DS that connects the transactions with the record-types.

INFORMATION AND SOFTWARE TECHNOLOGY 1990年第5期32卷 357-369页

作者： SHOVAL, P MANOR, O Computer and Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University of the Negev P.O. Box 653 Beer Sheva 84105 Israel.

In software engineering, computer-aided software engineering tools are used to implement the methodologies of development in an automated or semiautomated environment. A number of tools are presented that were developed to support ADISSA (Architectural Design of Information systems Based on Structure Analysis), a comprehensive methodology that treats analysis, design, and data modeling aspects as stages of a continuous process. This methodology covers in a unified way the stages of functional analysis, transactions (process) design, interface design, database schema design, input-output design, and structured prototyping. The personal computer-based ADISSA-supporting tools provide an automated environment that enables the analysts or designers, who work according to the methodology, to draw hierarchical dataflow diagrams and check their correctness, to design the transactions of the systems, the interface - a menu-tree - and the database schema, and to maintain an integrated data dictionary.

This paper is emphases on the financial impact of RFID system on the healthcare. The main obstacle of RFID implementation is the high costs hence the area of application must be very selective. We decide on the Obstetrics and Gynecology Department (OGD), where the patient has many visits during three different periods: Pregnancy, Delivery and after Childbirth. This research conducted over two years to collect real data for two different scenarios, traditional versus RFID systems. The reductions in waiting times for each period are valued into money. The RFID technology can significantly improve the processing times associated with medical record retrieval, dispensing medication, personnel management and billing. This analysis is planned for a period of 5 years with discount rate of 4%. Finally, the net present value concept is applied in order to compare the financial benefit of two systems and to obtain the payback period. © 2012 IEEE.

Establishing an effective and secure operating and logistics base under austere conditions, either at home or abroad, regardless of whether the origin of the crisis is military or strictly humanitarian in nature, is a complex mission. Unfortunately, the doctrine supporting the life-cycle management of base camp facilities is poorly codified and usually unstructured due to the disparate nature of the governmental organizations tasked with accomplishing these missions. In order to overcome this problem, the Department of systems engineering at the United States Military Academy (USMA) at West Point has developed functional and non-functional requirements for, and has partially implemented a commercial-offthe- shelf (COTS) knowledge management (KM) system that facilitates the sharing of this type of specialized information for military and civilian members of the "Base Camp Community of Practice (CoP)".
