scheduling of production in flexible manufacturing systems (fmss) has been extensively investigated over the past years and it continues to attract the interest of both academic researchers and practitioners. the generation of new and modified production schedules is becoming a necessity in today’s complex manufacturing environment. genetic algorithms are used in this paper to obtain an initial...

We present an approach to distributed planning and coordination architecture for dynamic non-deterministic multiactor mixed-initiative environment. The system provides flexible planning, replanning, and task allocation. The key idea of the presented approach is in integration of (i) I-X hierarchical planner with (ii) agent-based architecture and (iii) commitment-based plan representation. The i...

Dynamic linking lets programs use the most recent versions of classes without re-compilation. In Java and .NET, bytecode specifies which classes should be dynamically linked. This information represents the compiler’s knowledge of the compilation environment, but the execution environment might be different. For example, the execution environment on a mobile phone might provide fewer, simpler c...

Abstract One of the basic assumptions in hub covering problems is considering the covering radius as an exogenous parameter which cannot be controlled by the decision maker. Practically and in many real world cases with a negligible increase in costs, to increase the covering radii, it is possible to save the costs of establishing additional hub nodes. Change in problem parameters during the pl...

Force control is very important for many practical manipulation tasks of robot manipulators, such as, assembly, grinding, deburring that associate with interaction between the end-effector of the robot and the environment. Force control of the robot manipulator can be break down into two categories: Position/Force Hybrid Control and Impedance Control. The former is focused on regulation of both...

a nonlocal beam model based on the bernoulli–euler beam theory is presented to investigate the dynamic stability of embedded single-walled carbon nanotubes (swcnts) in thermal environment under combined static and periodic axial loads. the dynamic stability analysis is carried out by including the effects of small-scale parameter, temperature change and elastic medium. the equation of motion is...

the aim of this study was to investigate the effect of competencies and environmental factors on the success of rural entrepreneurs in kermanshah township. the statistical population consisted of 110 rural entrepreneurs that with using kerjci and morgan table, a sample size of 86 people were selected by random sampling technique. to collect the data, questionnaire was used. the analysis of find...

To inspect the 110kV power transmission line, inspection robot should be able to cross jumper lines of live lines. In this paper, a novel is designed, equipped with centroid adjustment mechanism make it capable crossing line smoothly. The various obstacle modes and proper planning are designed. Also, rigid-flexible coupling dynamic modeling method in flexible cable environment studied, which he...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

this paper presented a mixed integer programming for integrated scheduling and process planning. the presented process plan included some orders with precedence relations similar to multiple traveling salesman problem (mtsp), which was categorized as an np-hard problem. these types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...
