1. Research and Applications of Shop Scheduling Based on Genetic Algorithms
ABSTRACT Shop Scheduling is an important factor affecting the efficiency of production, efficient scheduling method and a research and application for optimization technology play an important role for manufacturing enterprises to improve production efficiency, reduce production costs and many other aspects. Existing studies have shown that improved genetic

2. Escalonamento de aplicações paralelas: de clusters para grids
Different algorithms provide efficient scheduling of parallel applications on distributed and heterogeneous computational platforms, such as computational grids. Most scheduling algorithms for such environments require an application model represented by a directed acyclic graph (DAG), selecting tasks for execution according to their processing and communica

3. Modelagem e programação de sistemas a eventos discretos periodicos / Modelling and programming of periodic discrete events systems
A methodology to obtain a cyclic scheduling in Discrete Events Systems is proposed in this work. This methodology initializes with a Petri netmodeling a discrete events system functioning with periodic processing. The method identifieswhich are the nets that can be treaties by him. The tractable Petri nets will be decomposed in subnets identified by process,

4. A general framework for simultaneous cyclic scheduling and operational optimization of multiproduct continuous plants
This paper addresses the problem of integrating in a single model operational optimization and cyclic scheduling of continuous plants. Considered are multiproduct, multistage plants with finite intermediate storage capacity (FIS). A combined optimization approach introduces synergic effects for more effective scheduling and plant operation (Alle and Pinto, 2

5. SIMULTANEOUS SCHEDULING AND OPERATIONAL OPTIMIZATION OF MULTIPRODUCT, CYCLIC CONTINUOUS PLANTS
The problems of scheduling and optimization of operational conditions in multistage, multiproduct continuous plants with intermediate storage are simultaneously addressed. An MINLP model, called TSPFLOW, which is based on the TSP formulation for product sequencing, is proposed to schedule the operation of such plants. TSPFLOW yields a one-order-of-magnitude

6. Sintese de controladores para transitorios em escalonamento de job shop ciclico
A cyclic scheduling is a sequence of tasks, infinitely repeated by a set of machines. Cyclic scheduling arises in job-shop problems whenever several products are regularly produced at the same rate, with setup cost and time negletable. A steady-state solution for this problem is assumed to be known. We also assume that the system is subject to disturbances (
