In this paper, we propose a novel implementation of the branch-andbound algorithm on a system with GPUs (Graphics Processing Units) using the Compute Unified Device Architecture (CUDA) approach. The developed implementation is used for solving a real-world problem – the optimal selection of the chemical equipment for multi-product batch plants. We propose two implementations for the searching a...

vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. the problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. this paper propose...

We here introduce a Multi-Agent System (MAS) approach for solving the crew resources assignment problem whenever a ship, under attack, suffers several damages and, thus, priorities must be assigned in order for it to survive. In the designed system, the ship is the MAS environment and the attacker, equipment, crew and officers (these last ones seen as decision makers) are represented through ag...

The design of facility layouts involves a decision process which, in general, due to its complexity, has to be decomposed into several sub-problems, namely: the selection of the most adequate manufacturing processes, the planning of equipment and labour requirements, the allocation of manufacturing operations to machines, the grouping of machines into sections (cells or departments), the select...

Here, we propose a fuzzy analytic hierarchy process (FAHP) method to evaluate the alternatives of enterprise resource planning (ERP) system. The fuzzy AHP approach allows the users get values more accurately to model the vagueness which changes according subjective ideas in the decision-making environment for ERP system selection problem. Therefore, fuzzy AHP method is used to obtain firm decis...

Intelligent manufacturing equipment constitutes important prerequisite and foundation for processing manufacturing. In its conceptual design process, functional determination based on customer needs (CAs), intelligence demands (IDs) manufacture constraints (MCs) is the basis subsequent work. As these various requirement information becomes more complex mixed, a practical method will improve eff...

Selection of the proper dilatation hardware in performing coronary angioplasty will facilitate the procedure, minimize its cost, and enhance its safety. Over the past 3 years, there has been an acceleration of growth in PTCA catheter and wire technology. We evaluated all currently approved dilatation systems as well as some investigational equipment and herein discuss their relative merits and ...
