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;un...

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.

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.

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.

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 systemsengineering 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)".
Purpose: This viewpoint aims to present reflections on the coronavirus disease 2019 (COVID-19) pandemic scenario and the entrepreneurial potential of Brazilian students. Guidelines are proposed to support debates in t...
