Production Orders

The way enterprise capabilities are used decides about its competitiveness among other ones. In that context modeling aimed at production tasks allocation planning plays a crucial role especially at concurrently executed production orders. The introduced reference model employing constraint programming (CP) paradigm describes both an enterprise and a set of project-like production orders. Moreover, encompassing consumer orders requirements and available production capabilities, the model provides the formal framework allowing one to develop a class of decision support systems aimed at interactive production process planning subject to multiproject environment constraints. In that context our contribution is a knowledge-based and CP-driven approach to resource allocation assuming precise character of decision variables. The conditions sufficient for deadlock avoidance are the main goal. The conditions delivered provide formal framework for developing a task oriented Decision Support Tool for Project Portfolio Prototyping (DST4P, Banaszak 2006). The tool provides a prompt and interactive service to a set of routine queries formulated either in straight or reverse way.

Graphical Visualization

The objective of this article is to discuss the usability and suitability of having graphical visualization tools for decision support in Space monitoring systems. Operators dealing with specific Space missions are burdened with continuous real-time telemetry data about components’ behavior and they have to take quick actions when some malfunction occurs. To have a decision support tool for monitoring what is happening is essential for ensuring the mission success. In this work, for discussing interface usability concerns for decision support, we use a real case study, called MODI-Monitoring and Diagnosis for Mars Driller project (MODI, 2006), which was financed by the European Space Agency (ESA). The MODI objectives were the development of a fuzzy alarm fault detection system as well as a fuzzy terrain-hardness detection system, for the drill device included in the ExoMars rover (ExoMars, 2007). Although a number of positive results have been achieved using different knowledge-based technologies for monitoring, diagnosis and control, for instance inference systems, expert systems, data mining, fuzzy logic, and so forth (Isermann, 1998; Ross, 2004), only recently attention on the usability and suitability of graphical visualization interfaces, acting as a decision support tool, is starting to be considered a relevant issue in software applications (Nunes, in press).

Production Orders

Purpose This paper aims to provide a method and decision support tool to enhance swift reconfiguration of Plug&Produce (P&P) systems in the presence of continuously changing production orders. Design/methodology/approach The paper reviews different production scenarios and system design and configuration methods and more particularly specifies the need of decision support tools for P&P systems that integrate configuration and planning activities. This problem is then addressed by proposing a method that helps reduce the solution space of the reconfiguration problem and allows the timely selection of the most promising reconfiguration alternative. Findings The proposed method was found to be helpful in reducing the reconfiguration alternatives that need to be considered and in selecting the most promising one for different orders. The advantages and limitations of this method are identified, and an illustrative test case of the approach is presented, corroborating the method applicability in the absence of large queues in the system. Originality/value This paper addresses a less explored domain within the P&P systems research field, which is the system reconfiguration. It proposed a method to support system validation and reconfiguration jointly with an illustrative test case. This represents an original contribution to the P&P research field, and it can have impact in improving agility and decreasing the complexity of reconfiguration activities to cope with constantly changing production orders.
