Application of learning pallets for real-time scheduling by use of artificial neural network
2011
Author's version of a chapter in the book: 5th International Conference on Software, Knowledge Information, Industrial Management and Applications (SKIMA). Also available from the publisher at: http://dx.doi.org/10.1109/SKIMA.2011.6089986 Generally, this paper deals with the problem of autonomy in logistics. Specifically here, a complex problem in inbound logistics is considered as real-time scheduling in a stochastic shop floor problem. Recently, in order to comply with real-time decisions, autonomous logistic objects have been suggested as an alternative. Since pallets are common used objects in carrying materials (finished or semi-finished), so they have the possibility to undertake the …

Latest advancements in manufacturing systems at NAMRC 45
2017
Latest manufacturing technologies are more prevalent thanbefore due to recent industrial revolution (or Industry 4.0), continu-ous business decentralization and needs for better overall resourceefficiency and effectiveness. Manufacturers are competing in aglobal, dynamic marketplace that demands excellence in qual-ity and service, throughput, innovativeness, agility in production,short response time to changing markets, and tight profitable mar-gins. In the 21 st century, manufacturing will be gradually pushedtowards a distributed environment with increasing dynamism oruncertainty. It is envisioned that Cyber-Physical Systems (CPS),Cloud Manufacturing, Internet of Things, and Big Data Analy…
Integrated Approach to Part Scheduling and Inspection Policies for a Job Shop Manufacturing System
2007
The quality of a product greatly depends on the quality of its components. This requires that manufacturing specifications have to be met in the manufacturing environment and as a consequence inspection stations are present in many manufacturing systems and inspection policies must be adopted. One problem, which has been widely investigated, concerns the detection of the inspection points in the hypothesis that the action to be taken is known when a defective part is detected. If different jobs are to be produced, then operation scheduling becomes yet another complex problem needing to be solved. And while the problem of scheduling has received a great amount of attention from researchers, …
A Reference Scenario for IMS Strategic Design
1999
Today is fully acknowledged that manufacturing is a formidable competitive weapon. The strength of such a weapon is essentially defined during the first step of the design phase called strategic design. During this phase, in fact, the principal characteristics of the manufacturing systems are to be defined taking into account the competitive environment and the competition strategy. Classical analytical models for IMS design often neglect this aspect and, perhaps, this is one of the causes of IMS failure. The paper proposes a set of analytical models for strategic IMS design; they have been classified into four classes, each one pursuing a determined set of objectives, providing, in this wa…

ROBUST CONTROL STRATEGIES FOR MULTI—INVENTORY SYSTEMS WITH AVERAGE FLOW CONSTRAINTS
2006
Abstract In this paper we consider multi—inventory systems in presence of uncertain demand. We assume that i) demand is unknown but bounded in an assigned compact set and ii) the control inputs (controlled flows) are subject to assigned constraints. Given a long—term average demand, we select a nominal flow that feeds such a demand. In this context, we are interested in a control strategy that meets at each time all possible current demands and achieves the nominal flow in the average. We provide necessary and sufficient conditions for such a strategy to exist and we characterize the set of achievable flows. Such conditions are based on linear programming and thus they are constructive. In …
Automated vehicles' work planning in flexible manufacturing systems
2006
The problem of rules setting in coordination of automated vehicles access to shared system resources (sections of their transportation paths) which assure a deadlock free and starvation free flow of the executed processes belongs to NP-hard problems. Assuming that there are local (controlling access to shared resources) rules of priority dispatching, the problem deals with setting conditions sufficient for a pair (initial state, set of priority dispatching rules). The assumed knowledge base way of specifying a transportation subsystem leads to solving a logic-algebraic method decision problem. In this regard, the working knowledge representation synthesis method constitutes a significant co…
